The hot air circulation oven, also known as the electric blast drying oven, is based on the principle of using a fan to circulate and supply air uniformly and efficiently. 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. The hot air circulation oven is widely used for sterilization and drying of various materials, rubber stoppers, aluminum caps, and antibiotic bottles. It uses stainless steel electric heating rods for heating (or steam heating) and a direct cooling fan for hot air circulation, which heats up quickly and has high sterilization efficiency. It can automatically display and control the temperature, record the temperature, and alarm in a timely manner if it exceeds the temperature limit.
Structural characteristics of hot air circulation oven:
The drying box body of the hot air circulation oven is made of angle steel and thin steel plate. Fill the space between the shell and the studio with fiberglass insulation. The heating system is installed at the top of the studio. This type of drying oven equipped with air blower can effectively avoid the gradient temperature difference and temperature overshoot phenomenon in the working room, and can improve the temperature uniformity in the working room.
