For the drying of goods, the main way is the three kinds of direct heating, vacuum suction, or hot air circulation heating.

The first kind of drying, oven, the most traditional heating method is electric drying. This is a common oven, and it is also a principle that everyone knows. This aspect of the oven can be better understood by everyone. It is also similar to fire drying, which is mainly used for metals. Food items that do not require much drying speed are most suitable for drying with this kind of oven.

The second kind of drying, air drying oven, the main principle of this kind of drying oven is hot air circulation drying. It has high requirements for drying speed, mainly aiming at the short drying time. The hot air circulation oven is in place for this convenience. It can quickly take away the humidity on the articles under the hot air circulation, making full use of the principle of evaporation. It can dry things in a short time. The disadvantage is easy to oxidize the surface of the object, or damage the surface structure of the object.

The third kind of vacuum drying oven, this drying method is a ghost axe magic way. It can dry the articles without any change in the surrounding environment. It is mainly designed for drying heat sensitive, easily decomposed and easily oxidized substances. The design is seamless. Completely avoid changes in the drying process. This kind of drying oven is also the mainstream of the development of science and technology, but the price is a little expensive.
