Hot air circulating electric oven

The air circulation system of the hot air circulation oven adopts a fan circulation air supply method, with uniform air circulation and high efficiency. The air source is driven by a circulating air supply motor (using a contactless switch) to drive the wind turbine through a heater, and then the hot air is sent out through an air duct to the interior of the oven. The used air is then sucked into the air duct to become the air source for further circulation and heating. Ensure indoor temperature uniformity. When the temperature value swings due to the action of opening and closing the door, the air supply circulation system quickly resumes operation until it reaches the set temperature value

Structure of hot air circulation oven

The hot air circulation oven is composed of angle steel, stainless steel plate, and cold steel plate.

The insulation layer is filled with high-density aluminum silicate cotton, which ensures the insulation performance of the oven.

The installation position of the heater can be at the bottom, top, or both sides.

Use a digital intelligent instrument (see figure on the right) to control the temperature. There are two types of air duct designs for hot air circulation ovens: horizontal air supply and vertical air supply!

Application of oven

Hot air circulating oven is used for heating, solidifying, drying and dehydrating materials in industries such as pharmaceuticals, chemicals, food, agricultural and sideline products, aquatic products, and light industry. Such as raw materials, traditional Chinese medicine decoction pieces, extracts, powders, granules, dehydrated vegetables, etc.

Scope of application of oven

Hot air ovens are suitable for baking items with chemical gases and food processing, curing inks, drying paint films, etc. They are widely used in precision baking, drying, tempering, preheating, shaping, processing, etc. for electronics, motors, communications, electroplating, plastics, hardware chemicals, instruments, printing, pharmaceuticals, PC boards, powders, impregnation, spraying, glass, wood building materials, etc; Internal heat cycle ensures even heating of baked objects.
