The principle of electric blast drying oven

The electric thermostat blast drying oven is also called the hot air circulation oven, which is the name based on its working principle. However, in actual industrial production, there are different names according to different industries and different dry materials. For example, in the chemical industry, it is called high-temperature curing oven, and the outer layer treatment such as wire is called heat treatment oven. It is called high temperature aging box for rubber aging test, and it is called secondary vulcanization oven in secondary vulcanization process. Their working principle is actually the same.

If you want to understand the working principle of the electric thermostat blast drying oven, you must first have a clear understanding of the basic structure of the oven. The electric heating constant temperature blast drying box is mainly composed of a heat source, a fan, a duct and a temperature control system. Below I will tell you in detail about the various components of the electric thermostatic blast drying oven.

There are many heat sources, such as thermal oil, steam heating and electric heating. Of course, the most common one is electric heating. Electric heating generally uses electric heating wire or electric heating tube as the main heating element. The principle can refer to the hair dryer, the fan blows the air to the electric heating wire, and the air is heated and then blown out from the front air cylinder.

Air duct: A special structure designed according to fluid mechanics to orient the circulating airflow so that the air convects in the flow we need.

The temperature control system consists of a temperature sensor and a temperature controller. There are usually multiple temperature sensors in the oven, and multiple temperature parameters are collected and transmitted to the temperature controller. The controller adopts PID self-tuning adjustment, and adjusts the fan circulation mode according to multiple temperature parameters to regulate the temperature.

When the hot air in the drying chamber heats the material, the water becomes water vapor mixed into the hot air. The air in the tank is convected by a fan, and the hot air with water vapor is discharged through the exhaust hole. At the same time, the air in the intake hole is sucked into the heat circulation of the box. Through the constant exchange of indoor and outdoor air, moisture is also taken out of the box to achieve the purpose of drying. The amount of air exchange inside and outside the tank can be adjusted by changing the size of the pores.

The above is the principle of electric heating constant temperature blast drying oven. The heating element of the dry box with poor quality is usually exposed to the air, which is easy to oxidize for a long time and affects the service life. The drying oven produced by our company uses an electric heating tube, that is, the heating wire is located inside the heating tube, which not only can effectively reduce the oxidation rate and increase the service life. At the same time, the heating tube itself increases the heat transfer area and has higher thermal efficiency.
