In precision manufacturing fields such as electronics, semiconductors, and aerospace, industrial vacuum ovens are by no means simple "heating equipment". Instead, they have become core equipment for ensuring product quality by virtue of their ultimate control over the environment. Their performance advantages always revolve around "precision temperature control and efficient drying in a vacuum environment", which directly determine the reliability and qualification rate of downstream products.
I. Vacuum Performance: From Environmental Control to Quality Assurance
Vacuum degree is the core indicator of industrial vacuum ovens, which is directly related to drying efficiency and material safety. High-quality equipment can usually achieve a high vacuum degree below 10Pa, and some semiconductor-specific models can even reach the level of 1Pa. This performance brings dual values:
Oxidation Prevention in Low-Oxygen Environment: The oxygen content is greatly reduced in a vacuum state, which effectively prevents heat-sensitive and oxidizable materials (such as positive and negative electrode materials of lithium batteries, precision metal components) from oxidative discoloration and performance degradation during the heating process. It is particularly suitable for the processing of high-strength alloy components in the aerospace field.
Boiling Point Reduction to Accelerate Drying: The vacuum environment significantly lowers the boiling point of solvents. For example, the boiling point of water is only about 55℃ under a vacuum of -0.098MPa, which can quickly remove moisture or organic solvents inside the material at low temperatures. This solves the problem of "surface crusting and internal dampness" in traditional hot air drying, and is especially suitable for moisture removal of electronic components before packaging.
It is worth noting that the stability of the vacuum system is also crucial. Ovens equipped with high-quality vacuum pumps and pressure sensing devices can realize real-time monitoring and automatic compensation of vacuum degree, avoiding process failure caused by vacuum leakage.
II. Temperature Control Performance: Dual Perfection of Precision and Uniformity
The strict temperature requirements in industrial production have promoted the upgrading of vacuum ovens from "rough heating" to "precision temperature control". Their core performance is reflected in two aspects: temperature control precision and temperature uniformity:
1. High-Precision Temperature Control: Equipment adopting a PID closed-loop temperature control system can achieve a temperature control precision of ±1℃, and some high-end models even realize a fluctuation control of ±0.5℃. This precision ensures that the processing conditions of each batch of materials are completely consistent in mass production. For example, in the semiconductor chip packaging process, it can accurately control the melting and solidification temperature of the solder to avoid cold soldering problems.
2. Whole-Domain Temperature Uniformity: Through the distributed layout of multiple heating tubes and the optimized design of hot air circulation, the temperature dead zones in the oven are effectively eliminated. The temperature difference between various points in the working chamber is usually ≤±3℃. For special-shaped materials such as large-area PCB boards and photovoltaic modules, a uniform temperature field can avoid deformation caused by local stress concentration.
III. Efficiency and Adaptability: Meeting Industrial Production Needs
The high productivity requirements in industrial scenarios require vacuum ovens to balance efficiency and flexibility while ensuring performance:
• Rapid Temperature Rise and Fall: Equipment equipped with stainless steel heating tubes and high-efficiency thermal insulation layers can achieve a heating rate of 5-10℃/min. During the cooling stage, the combination of vacuum bubble breaking and forced air cooling greatly shortens the processing time of a single batch, adapting to the fast-paced production in the electronics industry.
• Multi-Specification Adaptability: From small laboratory-level chambers (below 50L) to large tunnel-type vacuum ovens for production lines (with a volume of over 1000L), selections can be made flexibly according to material sizes. Some equipment also supports customized layered shelves and explosion-proof designs to meet the needs of special industries such as chemical engineering and military industry.
IV. Stability and Intelligence: Invisible Guarantee for Industrial Production
In continuous production, the stability of equipment directly affects productivity. Modern industrial vacuum ovens are generally equipped with:
• Multiple Safety Protections: Devices such as over-temperature alarms, abnormal vacuum shutdown, and door lock interlock avoid safety accidents caused by operational errors.
• Intelligent Control: The touch screen operation interface supports process parameter storage (10-20 groups of formulas can be preset). Some models can be connected to the MES system to realize real-time upload and remote monitoring of production data, reducing the cost of manual intervention.
In conclusion, the core performance of industrial vacuum ovens lies in "achieving a precise balance between temperature and efficiency based on a vacuum environment". In today's era where precision manufacturing is increasingly dependent on process stability, selecting a vacuum oven that adapts to one's own productivity and material characteristics is not only the key to improving product quality, but also an important part for enterprises to build core competitiveness.
The industrial multi-layer oven is a high-efficiency heating equipment designed for industrial mass production. Its core structural innovation lies in the vertical stacking of multiple independent chambers, which effectively breaks the space limitation of traditional single-layer ovens. It is widely suitable for mass drying and curing needs in electronics, automotive, new materials and other fields. Compared with ordinary heating equipment, it has significant advantages in space utilization, temperature control accuracy and production efficiency. Its core features and application fields are as follows:
I. Core Features
1. High Space Utilization: Adopts vertical stacking of multiple independent chambers, abandoning the "horizontal space occupation" limitation of traditional single-layer ovens. The effective heating space can be increased by 3-5 times under the same workshop floor area. This design is particularly suitable for the compact layout needs of modern industrial workshops, enabling larger batch workpiece processing in limited space and directly reducing the site rental and planning costs per unit capacity.
2. Precise and Uniform Temperature Control: Each chamber is independently equipped with a high-precision temperature control module and a closed-loop circulating air system, with temperature fluctuation strictly controlled within ≤±1℃. It also supports differentiated temperature and time parameter settings among different chambers for simultaneous processing of workpieces with multiple process requirements. The internal hot air forms 360o three-dimensional circulation through the deflector, completely eliminating temperature dead zones in the chamber and ensuring a temperature uniformity of ≥95%, which fundamentally guarantees the consistency of processing quality for batch workpieces and avoids product performance differences caused by temperature variations.
3. Energy Efficiency: The multi-layer shell is filled with high-density thermal insulation cotton and equipped with high-temperature resistant sealing strips to form a tight thermal insulation structure, reducing heat loss by 20%-30% compared with traditional single-layer ovens. Some mid-to-high-end models are also equipped with waste heat recovery devices, which can reuse the heat of hot air discharged from the chamber for air intake preheating, further improving energy conversion efficiency and meeting the energy-saving and consumption-reducing needs of industrial production.
4. Easy and Controllable Operation: Equipped with an industrial-grade PLC touch control system, supporting storage and batch calling of hundreds of sets of process parameters. With IoT modules, remote real-time monitoring and operation are achievable, significantly reducing manual intervention costs. The independent start-stop design of multi-layer chambers can flexibly adapt to order volume changes, facilitating small-batch and multi-batch flexible production. It also comes standard with over-temperature sound and light alarm, circuit overcurrent protection, door safety interlock and other devices, fully complying with industrial safety standards such as GB 50016 to eliminate potential production safety hazards.
II. Main Application Fields
1. Electronic Manufacturing: One of the core equipment for electronic component processing, widely used in PCB solder mask curing, moisture-proof drying of capacitors, resistors and other electronic components, and high-temperature heat treatment after chip packaging. Its precise temperature control capability can strictly match the heat resistance threshold of electronic components, effectively avoiding component performance degradation or damage caused by temperature fluctuations, and ensuring the stability and service life of electronic finished products.
2. Hardware and Auto Parts: Suitable for degreasing and drying of fasteners and stamping parts, removing residual oil on the workpiece surface through stable temperature. It is also used for shaping and drying of automotive interior parts (such as plastic panels, fabric cushions) and curing of surface coatings (such as electrophoretic paint, powder coating) on metal parts. Under high temperature, it can enhance the adhesion between the coating and the substrate, improving the wear resistance and corrosion resistance of the part surface.
3. New Materials and Composites: Meets the shaping and drying needs of carbon fiber products and glass fiber cloth during the molding process, ensuring uniform release of internal stress of materials through gradient temperature rise and improving the mechanical strength of finished products. It is also suitable for low-temperature drying of lithium battery electrodes, removing moisture from electrodes in a precise temperature-controlled environment of 40-60℃, avoiding the impact of moisture on battery electrochemical performance and safety performance, and ensuring the quality of new energy products.
4. Food and Pharmaceutical: Special models with 304 stainless steel inner tank and food-grade seals can be used for drying and preservation of food auxiliaries (such as dehydrated vegetables, baking raw materials) and sterilization and drying of pharmaceutical packaging materials (such as aluminum-plastic composite films, pharmaceutical glass bottles).
In summary, the core advantage of the industrial multi-layer oven lies in the precise balance between production capacity, space occupation and processing quality. Its high-efficiency, energy-saving and flexible characteristics perfectly meet the core needs of modern industrial mass production, and it has become an indispensable heating equipment for various industries to improve production efficiency and ensure product quality.
In modern industrial manufacturing, industrial precision ovens are key "temperature artisans". They are widely used in electronics, aerospace, automotive, medical and other fields, providing stable performance and reliable quality for products. Gaining an in-depth understanding of their principles not only clarifies the scientific logic of industrial production, but also helps practitioners use equipment efficiently to improve benefits.
(I) Heating System: The Source of Heat
The heating system is the "heat source core" of the oven. The thermostat controls the thyristor through signals to adjust the heater power and regulate heat output: full power is supplied when the temperature is much lower than the set value, power gradually decreases when approaching the set value, and output stops when the set value is reached. This is energy-efficient and achieves high temperature control precision.
(II) Air Circulation System: The Messenger of Heat Transfer
Composed of a blower motor, extended shaft and multi-wing fan blades, the air circulation system is critical for heat transfer. The motor drives the wind wheel to rotate and form air flow, which is evenly delivered to all areas of the oven through optimized air ducts, avoiding dead corners and temperature differences. Hot air fully contacts materials during circulation to achieve rapid and uniform heating, which is essential for high-precision processes such as electronic chips and optical lenses.
(III) Electrical Control System: The Core of Precise Operation
The electrical control system is the core control unit of the oven. The Q8 series electrical control system adopts full-touch operation with a control precision of 0.01 level and supports multiple sensor adaptations. It has 100 built-in processes (50 steps per group), including EVT, cold output and transmission output functions. The DO channel features safe isolation and arc suppression design, enabling convenient, accurate and reliable operation that adapts to diverse control scenarios.
Future Outlook: Technological Innovation Leads Development
In the future, industrial precision ovens will focus on three major innovation directions: intelligence, energy conservation and environmental protection, and special process adaptation, continuously innovating to shape a new industrial future.
As core industrial equipment for precise temperature control, drying and curing, precision ovens’ operational stability directly impacts product quality and production efficiency. Scientific maintenance extends service life and ensures process parameter accuracy. Below are key methods divided into daily basic maintenance and regular in-depth maintenance.
I. Daily Basic Maintenance: Safeguard Fundamental Operation
Daily maintenance, the first line of stable operation defense, is performed before startup, during operation and after shutdown—simple yet critical.
1. Comprehensive Cleaning: Eliminate Impurities
Wipe the oven cavity, shelves and door seal daily to remove debris, dust, cured stains or oil. Use neutral detergent and a clean cloth to avoid cavity corrosion. Regularly clean the exterior and heat dissipation holes for unobstructed heat dissipation.
2. Parameter & Safety Checks: Ensure Accuracy and Safety
Verify that temperature controller, timer and other parameters match process requirements before startup, and check for stable display without drift. Inspect door interlock sensitivity, power cords, heating tube terminals and cooling fan for abnormalities. Confirm emergency stop buttons and over-temperature protection devices function properly to eliminate hidden dangers.
3. Standardized Operation: Reduce Human-induced Wear
Avoid overloading workpieces and ensure proper spacing for hot air circulation to prevent local overheating. Follow the manual for temperature rise/drop—no sudden startup/shutdown or drastic adjustments to avoid furnace cracking. Turn off main power only when temperature drops below 50℃ to extend heating element life.
II. Regular In-depth Maintenance: Enhance Core Performance
Recommended monthly or quarterly, regular maintenance focuses on core components and requires professional technicians.
1. Heating & Circulation System Overhaul: Ensure Efficiency
Inspect heating tubes for oxide layers, scale or abnormal resistance (replace if needed), and clean/fasten junction box terminals with insulating grease. Disassemble fan impellers to remove dust and oil, lubricate bearings, replace damaged seals and adjust air duct baffles for uniform hot air circulation.
2. Temperature Control Calibration: Improve Accuracy
Calibrate temperature sensors with a standard thermometer—adjust parameters or replace sensors if deviation is excessive. Inspect signal transmission lines for interference or poor contact. Verify multi-stage heating curve accuracy for programmable ovens.
3. Furnace Structure Maintenance: Extend Service Life
Check insulation layers for damage and refill insulation material if heat dissipation is abnormal. Replace aged or deformed door seals. Repair the cavity’s high-temperature resistant coating to prevent rusting.

An industrial high-temperature aging oven is a device that conducts accelerated aging tests on industrial products (such as electronics, electrical appliances, components, chemical materials, etc.) by simulating high-temperature environments. By applying high-temperature stress, potential defects and faults of the products can be exposed in advance, thereby screening out early-failed products and enhancing the reliability and stability of the products leaving the factory. Its core components mainly include the heating system, circulation system, control system and safety protection system.
Main features: Firstly, it has a wide operating temperature range, typically from room temperature +10°C to +200°C or 300 °C. Temperature uniformity is a key indicator for evaluating the performance of an oven. The temperature difference at each point inside the oven is ±2°C, and the temperature control accuracy usually reaches ±0.1°C to ±1°C, ensuring the precision and repeatability of the test conditions. In addition, the heating rate can be set according to the test requirements, ranging from linear heating to rapid heating. The internal structure of the test chamber is usually made of stainless steel (such as SUS304), which is heat-resistant and corrosion-resistant. The shell is generally made of high-quality cold-rolled steel plate and the surface is treated with plastic spraying. Finally, the insulation layer is usually made of high-density aluminosilicate cotton or rock wool, with sufficient thickness to ensure that the surface temperature of the box is low and energy-saving. The air duct is designed for horizontal or vertical air supply to ensure that the hot air can flow evenly through each product under test.
Aging ovens are widely used in all industries that have high requirements for product reliability:
Electronics industry: IC chips, PCB circuit boards, power supplies, chargers, LED displays/lamps, automotive electronics, etc.
Electric appliances: transformers, relays, capacitors, circuit breakers, motors, etc.
Communication products: mobile phones, routers, base station equipment, optical modules, etc.
Chemical materials: Conduct high-temperature aging resistance tests on coatings, plastics, rubbers, adhesives, etc.
Automotive parts: various sensors, controllers (ECUs), wiring harnesses, etc.
How to choose the right industrial high-temperature aging oven? When making a choice, the following factors need to be comprehensively considered:
1. Temperature range: According to the product testing standards, select the model that can meet the highest and lowest temperature requirements, and leave a certain margin.
2. Inner box size: Select an appropriate volume based on the size and quantity of the products to be tested. Remember to reserve space to ensure air circulation.
3. Temperature uniformity and accuracy: The higher the requirements, the higher the equipment cost and manufacturing difficulty. Choose according to the strictness of the test.
4. Load condition: If the product will generate heat by itself during the testing process (i.e., "load testing"), it is necessary to inform the equipment manufacturer so that they can calculate and configure sufficient heating and heat dissipation capacity.
5. Control System and Functions:
Is program control (multi-stage temperature rise and heat preservation) required?
Is it necessary to record and export the temperature curve data?
Whether remote monitoring and other factors are needed
Industrial high-temperature aging ovens are an indispensable part of modern quality engineering. Through sample aging tests, it intercepts potential faulty products before they leave the factory, significantly reducing the market return rate and after-sales maintenance costs, and earning credibility and long-term benefits for the enterprise. When making a purchase, you can communicate fully with us based on the characteristics of your own products and testing requirements, and choose the most suitable solution.
1.Core customization requirement analysis
1.1 The standard box size or load-bearing capacity (such as automotive parts, large unmanned aerial vehicles, and entire cabinet servers) cannot meet the requirements. Special sample racks, trays or suspension devices are required. The test samples need to be powered on and run inside the box, and connected to cables or pipes (such as battery pack charge and discharge tests, engine component tests). Oil stains, particulate matter or corrosive gases may be released during the sample testing process.
1.2 It needs to be connected with mechanical arms and AGV carts to achieve automatic loading and unloading. The heating and cooling rates required far exceed the standard specifications (such as >15°C/min).
1.3 The equipment needs to adapt to specific room sizes, door opening sizes or floor heights. There are special requirements for the power supply (if it cannot meet 380V) and the cooling water source (if a cooling tower cannot be provided).
2. Key customized technical specifications
2.1 Customized Dimensions
The internal effective space is determined entirely based on the size and quantity of the customer's samples. The minimum distance between the sample and the box wall needs to be considered to ensure uniform airflow. It is necessary to clearly define the size of the door, the material of the sealing strip, the door lock mechanism (mechanical lock, pneumatic auxiliary lock), and the size and quantity of the observation window. The inner box is usually made of SUS304 stainless steel. The outer box body can be made of high-quality steel plate with plastic spraying or SUS304. For corrosive tests, more durable materials should be specified. Test holes are used for leads. The size, quantity and position of the hole diameters (such as left or right) need to be customized, and sealing plugs or flanges should be provided.
2.2 Confirm the test interval
The technical index standards for temperature are usually from -70°C to +150°C. The standard heating and cooling rate is 1 to 3°C/min. Linear rapid temperature change: 5 to 10°C/min. Nonlinear rapid temperature change: Customizable to 15°C/min or even higher. This is directly related to the power configuration of the refrigeration and heating systems and is a key factor influencing the cost. Customize stricter control accuracy, such as uniformity ≤±1.0°C and fluctuation ≤±0.5°C.
2.3 Refrigeration System
Air cooling: Suitable for sites where the ambient temperature is not high and the ventilation around the equipment is good.
Water cooling: It is suitable for large cooling capacity, high heat generation samples, or situations with high ambient temperatures. It is more efficient but requires a cooling tower.
Cascade refrigeration: It is used for low-temperature requirements below -40°C and usually adopts two-stage cascade.
2.4 Installation Method
The refrigeration system of the integrated machine is located at the top or bottom of the box, with a compact structure and convenient installation. The split-type refrigeration unit is separated from the box body and is suitable for high-power equipment. It can discharge noise and heat to the outside, but the installation is complex.
2.5 Control System and Software
The controller customizes the size and brand of the color touch screen, supports multi-segment programming, program group loops, step jumps, etc. Customized LAN interface for connecting to the upper computer (computer) for data monitoring and recording. Whether it is necessary to support remote network monitoring and operation, as well as customize record intervals and storage capacity.
2.6 Independent sample over-temperature protector.
Compressor overheat, overcurrent and overpressure protection; Fan overcurrent protection Cooling water cut-off protection and automatic stop test function when the door is opened; Leakage or short-circuit protection; Sound and light alarm prompt.
Customizing double-door temperature test equipment is a systematic project. The key to success lies in the clarification and refinement of the initial requirements. A detailed and unambiguous "Technical Requirements Document" serves as the cornerstone for communication between equipment suppliers and customers. It ensures that the final delivered equipment fully complies with testing, process, and site requirements, avoiding subsequent disputes and cost overruns.
The core function of adding nitrogen input in industrial ovens is to create an inert atmosphere environment with low oxygen or no oxygen. This is usually referred to as "nitrogen protection" or "nitrogen-filled baking".
Preventing oxidation is the most common and primary purpose. When heated in the air (with an oxygen content of approximately 21%), many materials will undergo oxidation reactions, thereby affecting product quality. Adding nitrogen input to industrial ovens can prevent the formation of oxide scale (such as rust) on the surface of metal products during heating, keep the metal bright and clean, and improve the quality of subsequent processes such as electroplating and spraying. Or to prevent the oxidation of component pins, pads and precision films at high temperatures, ensuring the quality of soldering and the long-term reliability of the product. At the same time, it can also prevent chemical and powder materials from undergoing chemical reactions with oxygen at high temperatures, thereby altering their chemical properties.
2. Some materials pose a risk of fire or explosion in high-temperature and oxygen-rich environments. Increasing nitrogen input can suppress combustion and explosion.
In industries such as printing and coating, a large amount of flammable organic solvents (such as alcohol, acetone, and toluene) are volatilized during the baking process. Introducing nitrogen to reduce the oxygen concentration below the limit oxygen concentration can completely eliminate the risk of fire and explosion, which is an important safety measure. For metal and plastic powders, when they reach a certain concentration in the air, they are highly prone to explosion when exposed to open flames or high temperatures. Nitrogen protection can create a safe processing environment.
3. Improve process control and product quality. Heating in an oxygen-free or low-oxygen environment can avoid many side reactions caused by oxygen. In processes such as chip manufacturing and solar cell production, extremely high cleanliness and an oxygen-free environment are essential to prevent the oxidation of silicon wafers, metal electrodes, etc., ensuring extremely high product yield and performance.
4. While filling the oven with nitrogen, the air that originally contained moisture and oxygen inside the oven will also be "driven out". This not only prevents oxidation but also plays an auxiliary drying role, making it particularly suitable for products that are extremely sensitive to moisture.
In conclusion, adding nitrogen input to industrial ovens is to actively control the heating environment rather than passively heating in the air. This is an important technical means used in high-end manufacturing and precision processing.
Internal environmental conditions
Benchmark cleanliness: At the beginning of the test, the chamber must reach the highest cleanliness level it claims (such as ISO Class 5 / Class 100). This is the premise of all tests. Before the test, the oven needs to run a long period of "self-cleaning" until the particle count shows that the concentration is stable below the standard for multiple consecutive times.
Temperature and Humidity: Although the oven is a heating device, its initial state needs to be clearly defined. The initial environment for testing is usually normal temperature and humidity, for example, a temperature of 20±5°C and a relative humidity of 30-60% RH. This is crucial for testing the heating time and temperature uniformity. If the process has requirements for the dew point of the environment, it may be necessary to record the initial absolute humidity.
Airflow state: The test should be conducted under the specified airflow pattern, typically in a vertical or horizontal laminar flow state. The fan must operate at the rated speed, with stable air pressure and air volume.
Test load: The test is divided into two conditions: no-load and full-load. No-load is the benchmark test for equipment performance. Fill the effective working space with a fully loaded simulated load (such as metal, pallets, etc.) to simulate the harshest working conditions. Full-load testing can truly reflect the impact of products on air flow and temperature fields in actual production.
External environmental conditions
1. The cleanliness level of the external environment must be lower than or equal to the cleanliness level designed by the oven itself. For instance, when testing an oven of Class 100, it is best to do it in a room of Class 1000 or cleaner. If the external environment is too dirty, it will seriously interfere with the measurement results of the internal cleanliness of the oven when opening and closing the door or when water seeps through gaps.
2. The laboratory requires a stable temperature and humidity environment. It is generally recommended to conduct the test under standard laboratory conditions, such as 23±2°C and 50±10% RH. Avoid testing in extreme or highly volatile environments.
3. The test area should be free of strong convective winds and it is best to maintain a slight positive pressure to prevent external contaminants from entering the test area.
4. The power supply voltage and frequency should be stable within the range required by the equipment.
5. The equipment should be placed on a ground or base with less vibration. There are no large stamping equipment, fans or other strong vibration sources around.
When testing a dust-free oven, controlling the external environment is as important as measuring the internal environment. An unstable, dirty or strongly interfering external environment can lead to distorted test data and fail to truly reflect the performance of the equipment. All test conditions should be clearly recorded in the final verification report to ensure the traceability and repeatability of the tests.

A entrada de ar do forno de secagem é dividida em dois níveis de filtragem, a nova entrada de ar para o filtro intermediário, tornando o novo ar até 300.000, após o aquecimento de cada ciclo de ar quente com filtragem de filtro de alta eficiência e alta temperatura, de modo que o ar quente no forno de secagem tenha mais de 10.000 níveis de limpeza, para garantir que o processo de secagem seja limpo;4, O sistema é equipado com exaustor de umidade todo em aço inoxidável, e o módulo de programa PLC do sistema coleta a umidade no sistema para controle inteligente: De acordo com o sinal fornecido pelo instrumento de controle de umidade, o atuador do amortecedor da porta de umidificação é controlado pelo amortecedor. Ao mesmo tempo, o amortecedor é controlado pelo conversor de frequência para emitir a frequência correspondente de acordo com o tamanho do sinal de umidade, e o volume de ar razoável é descarregado para atingir o melhor efeito de umidificação e atingir uma umidificação razoável. A saída de umidade é equipada com um filtro de efeito médio para garantir a limpeza do ar de retorno da saída de umidade.5, Forma de aquecimento do forno: aquecimento a vapor ou elétrico. O material é aço inoxidável. Tem bom efeito de dissipação de calor e condições sanitárias. A faixa de flutuação é de cerca de ±1℃;6, O curso do sistema circulatório de ambos os lados da máquina principal ao mesmo tempo, concentrado no ar de exaustão do meio, em comparação com o design convencional para reduzir a diferença de temperatura entre os lados esquerdo e direito do forno; De acordo com as regras de orientação do volume de ar e pressão de ar da entrada e saída de ar, vários grupos de placas de perfuração com diferentes proporções são projetados como o dispositivo de distribuição do ar quente para dentro para obter uma diferença de temperatura menor. Além disso, o método de fixação da placa de rede de equalização de ar e do motor principal adota o método de fixação rápida, que pode limpar rapidamente o duto de ar de entrada e saída para garantir a limpeza da câmara;7, O equipamento é projetado com 5 saídas de esgoto na entrada de ar, skip e saída de ar, o que pode garantir que todo o esgoto seja descarregado rapidamente após a limpeza. As cinco saídas de esgoto são reunidas em um tubo principal para descarga centralizada, reduzindo a saída total de esgoto, para que a planta possa abrir menos ralos de piso;8. O equipamento no projeto do duto de entrada e saída pode cobrir todo o sistema de 7 portas de limpeza on-line, em circunstâncias normais para obter uma função de limpeza on-line rápida e simples, também pode ser configurado diretamente no dispositivo de limpeza on-line, a fim de obter o verdadeiro significado do CIP;9, A trilha do forno é talas convexas, e a placa inferior é conectada por soldagem de pé redondo, e o carro de secagem é equipado com pedal inclinado, o que torna o carro de secagem fácil de entrar e sair; Ao mesmo tempo, reduza o ângulo morto sem afetar o desempenho de purga; Tubo quadrado de aço inoxidável é usado para a coluna e aço angular de aço inoxidável é usado para a viga do forno, e a soldagem a arco de argônio é adotada. Rodas com rodas de nylon resistentes a altas temperaturas, cada secador com 2 rodas direcionais, 2 volantes. Todo o secador tem estrutura razoável, alta resistência, bonito e prático;10, O sistema de aquecimento do equipamento (aquecedor, filtro de alta temperatura e alta eficiência) é concentrado na câmara fechada de aço inoxidável, bom efeito de isolamento, alta limpeza e filtro de alta temperatura e alta eficiência para a estrutura de carregamento rápido do tipo gaveta, pode ser limpo e substituído rapidamente; As peças de conexão e o sistema são conectados com o design de instalação rápida de parafuso ajustável, o que é conveniente para manutenção e revisão;11, A trava da porta do forno adota trava de porta elástica ajustável avançada, bom desempenho de travamento, fácil de operar. Anel de vedação de borracha de silicone de alta temperatura e não tóxico é usado entre a porta e a caixa, que tem excelente desempenho de vedação. A camada de isolamento do forno adota lã de vidro ultrafina, que tem bom desempenho de isolamento térmico.12. Todos os flanges redondos do sistema são conectados por grampo de abertura rápida, e o método é projetado por parafusos borboleta de montagem rápida, o que facilita a desmontagem e limpeza da tubulação;13. Existem duas portas de verificação rápida no host do equipamento, o que é conveniente para verificar a temperatura e a umidade durante o processo de trabalho.
