Hot air circulation oven

The hot air circulation oven generally has a heating pipe, and the oven with a circulating fan can be called the hot air circulation oven, because no matter what structure of the oven, whether the wind direction is horizontal or vertical, in the final analysis, the hot air circulates in it, so it can be commonly called the hot air circulation oven, such as electric heating blast oven, opposite door high-temperature sterilization oven, etc. However, most of the hot air circulation ovens in the general industry refer specifically to the ovens shown in the above figure. Other ovens are evolved from the ovens shown in the above figure. For example, with the requirements of high-temperature sterilization, the fan is changed into an air-cooled standardized ring fan, the front and rear doors are opened, and the air duct is also changed, which becomes a double door high-temperature sterilization oven.
