This baking method has high thermal efficiency and ideal energy-saving effect, and is widely used for heating, curing, drying and dehydration of materials in food, agricultural and sideline products, aquatic products, medicine, chemical industry, electronic circuit boards, hardware, plastics, glass and other industries.
Typical examples are pcb circuit board ink resin, solder resist pre-baking, text screen pre-baking and curing; Food baking processing, dehydration of ingredients, pharmaceuticals and powder; Anti-fog, anti-rust, surface treatment coating curing, product material drying, internal and external moisture baking, etc.
The difficulties of hot air circulating oven are: the temperature is not easy to control, and the requirements for exhaust filtration system and energy saving level are high; Therefore, there may be great differences in the performance and energy efficiency of hot air circulation ovens between different manufacturers.
When choosing the manufacturer of hot air circulating oven, you should pay attention to the following points:
1. heating element: power efficiency, heating speed, energy saving level and service life.
2. Control system: control range of temperature zone and temperature difference, especially those requiring precise baking.
3. Exhaust filtration system: ensure the cleanliness level in the box and ensure the baking quality of products.
4. Air delivery system: the design of air pressure is reasonable, the hot air in the oven is evenly distributed and baked at constant temperature.
5. Safety protection: over-temperature power failure, fault alarm, leakage overload protection, etc.
