1. The size of the oven: refers to the production capacity. In terms of appearance, the larger the volume, the stronger the production capacity and the higher the purchase cost. The size of the production capacity is composed of some factors, such as the electric heating power and the production materials. Features, production of the largest space. Generally, you only need to look at the number of ovens (the racks for baking trays, but also the drying trays, such as chickens, ducks, etc.), single-door bicycles, two-door two-cars, two-door four-cars, four-door eight-cars. Each car can hold 10 baking trays, each of which is 640*460*50 (millimeters) in size, so that the required production size can be calculated and the appropriate oven can be selected.

2, the type of material: the type of material determines the structure and characteristics of the oven, such as: the material is powdery, can not use the hot air circulation oven, vacuum drying box series can be used (the wind may discharge the material with the wind out of the oven). Also, if you are not resistant to high temperature materials, these are all things to be aware of.

3. Type of oven structure: The air supply mode of the oven is divided into two types: horizontal air supply and vertical air supply. The appropriate structure can be selected according to the characteristics of the own materials.

4. Material selection: In all drying equipment, the choice of production materials is the main factor that directly reflects the purchase price. Different materials often have large prices, and the prices of stainless steel, iron plate and metal plate are very different. Including different types of stainless steel, the price is also different.
