Changzhou Tai'an drying equipment Co., Ltd. chooses hot air circulation oven. The hot air circulation oven adopts fan circulation air supply mode, because no matter what the structure of the oven, whether the wind direction is horizontal or vertical, in the final analysis, hot air circulates inside, and the wind circulation is uniform. The air source is driven by the circulating air supply motor and the air wheel passes through the heater to ensure the indoor temperature uniformity, and then the hot air is sent out through the air duct to the inner chamber of the oven. When the temperature value swings due to the action of opening and closing the door, the air supply circulation system quickly recovers, and then the used air is sucked into the air duct to become the air source for circulation and heating again. So we should choose hot air circulation oven professionally. The use and maintenance of the hot air circulation oven is also very important. When the oven is powered on, do not touch the part of the electric appliance on the left side of the oven by hand or wipe it with wet cloth or wash it with water. Do not place the articles in the oven too crowded. It is necessary to leave a space for natural convection of the atmosphere, so that the moist atmosphere can slow down and escape on the top of the air.
