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 production capacity is composed of some factors, such as the size of the electric heating power and the production material Features, maximum production space. Generally, just look at the number of ovens (the shelf where the baking trays are placed, and there are also those that do not use baking trays, such as chicken and duck drying). There are single-door bicycles, two-door two-cars, two-doors-four-cars, and four-doors-eight-cars. , Each vehicle can hold 10 baking pans, each of which is a standard 640*460*50 (millimeter unit) size. Based on this, 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. For example, if the material is in powder form, hot air circulation oven cannot be used, but a vacuum drying oven series can be used (the wind may discharge the material from the oven with the wind). Another example is materials that are not resistant to high temperatures. These are all things that need attention.

3. Oven structure type: 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 material.

4. Selection of materials: In all drying equipment, the selection of production materials is the main factor that directly reflects the purchase price. Different materials often have very different prices. The prices of stainless steel, iron plate, and metal-plated plate vary greatly. Including different types of stainless steel, the price is also different.
