Generally hot air circulation oven heating pipe, a circulation fan oven can be called hot air circulation oven, the oven because no matter what the structure, wind horizontal or vertical, in the final analysis are the hot air inside the loop, it can be known as a hot air circulation oven, such as electric blast oven, high-temperature sterilization oven door. But generally referred to in the industry circulating hot air oven or oven most especially as shown in figure, the other oven is evolved from the oven on the map, such as with high-temperature sterilization requirements, air-cooled centrifugal fan into circulation fan , front and rear door, duct also made a change, it becomes a high-temperature sterilization oven door. Shown hot air cycle is divided into five standard models. They are single door cycling, two two cars, two four-car, three six vehicles, four eight vehicles.
Hot air circulating oven air circulation system uses fans circulating air supply, uniform and efficient air circulation. Wind source is circulating air motor (using non-contact switch) driven by the wind wheel heater, but the hot air sent, and then through the air duct to the oven chamber, and then use air intake duct after becoming once again circulating air source, heating use. Make sure the room temperature uniformity. When the door switch operation caused due to temperature swings occur, the air circulation system quickly restore the operating state, until it reaches the set temperature value
