How do materials in drying equipment combine with moisture?

The purpose of drying equipment is to separate the material from the moisture in the material and get a product with low moisture content. If you don't know how the material in the drying equipment combines with the moisture, you will not understand the essence of the drying process of the drying equipment. There are many ways to combine materials and moisture in drying equipment.

Materials in drying equipment are generally in three ways: solid, liquid and gas. Liquid and gas I don't have much to explain here, you can see it with naked eyes, and it's relatively simple to dry. The following will focus on how the solid materials in the drying equipment combine with water.

In drying equipment, there are many ways to combine solid materials with moisture. The easier way to dry is to adsorb on the surface of materials. When this kind of material is dried, it only needs to use suitable temperature, and ordinary drying equipment can be used for drying.

It is a little difficult to dry than the surface adsorption of water. In this way, ordinary drying equipment can not dry quickly and effectively, so some drying equipment with complex structure design is needed, such as vacuum drying equipment and freeze-drying equipment.
