Tunnel drying oven is a device used for drying products.

1、 Working principle

Tunnel drying ovens usually use hot air circulation for drying. The air is heated by a heating device, and the hot air circulates in the tunnel under the action of a fan, exchanging heat with the dried product, thereby evaporating the moisture in the product and achieving the purpose of drying.

2、 Structural characteristics

1. Tunnel structure: generally composed of a feed inlet, a drying tunnel, and a discharge outlet. The product is driven by the conveying device and enters the tunnel from the feeding port. After the drying process, it is output from the discharging port.

2. Heating system: Electric heating, gas heating, steam heating and other methods can be used to select the appropriate heating method according to different drying needs.

3. Ventilation system: including fans, air ducts, etc., to ensure uniform distribution of hot air in the tunnel and improve drying efficiency.

4. Control system: It can accurately control parameters such as temperature, wind speed, and conveying speed to meet the drying requirements of different products.

3、 Application Fields

Widely used in industries such as food, medicine, chemical, electronics, etc. For example, in the food industry, it can be used to dry fruits, vegetables, meat products, etc; In the electronics industry, it can be used for drying circuit boards, electronic components, etc.

4、 Advantages

1. Continuous operation: capable of achieving large-scale and continuous production, improving production efficiency.

2. Good drying effect: By precisely controlling parameters such as temperature and wind speed, the drying quality of the product can be ensured.

3. Space saving: Tunnel style structural design, occupying a relatively small area.

4. Easy to operate: With a high degree of automation and simple operation, it reduces the intensity of manual labor.
