1. Principles and Regulations of Hot Air Oven

1. First, use the operating principle of the heat transfer properties of the mesh belt dryer to efficiently transfer heat between the boxes in the hot air oven.

2. The main oven has remaining heat during the heating process. When the remaining heat reaches a certain value, it will break through the main oven and transfer it to other subordinate ovens, so that other motor ovens can also be heated and run.

3. When the main oven gradually drops to a stable value from the high temperature at the beginning, the heat of the main oven will be absorbed by other ovens, and then the temperature of all ovens can reach a stable value. Then the effect of hot air circulation is reached, which is also the value performance of a fine high-temperature oven.

4. Hot air ovens generally have heating pipes, and ovens with circulating fans can be called hot air circulating ovens. Because no matter what the structure of the oven, the wind direction is horizontal or vertical. In the final analysis, hot air circulates inside, so it can be called hot air circulating oven. , Such as electric heating blast oven, side-by-side high-temperature sterilization oven, etc.

2. Air duct planning of hot air oven

1. Hot air oven, presumably we all have some understanding. The hot air oven adopts the air circulation system we planned for air circulation operation, and the air circulation is uniform and efficient.

2. Circulating air is generated by an axial flow fan and passed through a heater to form hot air, which is then sent out, and then to the oven boudoir through the air duct. The hot air that has been circulated for one cycle is circulated again through the air duct, which saves heat and also ensures the uniformity of the indoor temperature.

3. Regarding the structure of the hot air oven, we have also introduced it before, and today we will briefly introduce it in the form of a hot air oven drawing. The hot air circulation oven is mainly composed of angle steel, stainless steel plate and cold rolled steel plate.

4. Plan a reasonable air duct on the outer layer of the inner box, so that the hot air can circulate through the material and transfer heat to the material. The insulation layer is filled with high-density aluminum silicate wool, high-density aluminum silicate cotton ensures the heat preservation of the oven and the safety of the user. The heater is installed at the bottom, top, or sides.

​There are many things we need to pay attention to in the use of hot air oven. Only by mastering the correct method can we ensure that there will be no mistakes when using it, and it can also extend the service life of the hot air circulation oven.
