Abstract:

Drying equipment is also called dryer and dryer. The purpose of drying is for material use or further processing. For example, the drying of wood before making wooden molds and woodware can prevent product deformation, and the drying of ceramic blanks before calcining the two drying equipment can prevent the finished product from cracking. In addition, the dried materials are also easy to transport and store, such as drying the harvested grain to a certain moisture content to prevent mildew. Since natural drying is far from meeting the needs of production development, various mechanized dryers are more and more widely used.

Drying process needs to consume a lot of heat energy. In order to save energy, some materials with high moisture content, suspensions or solutions containing solid substances are generally dehydrated mechanically or heated to evaporate, and then dried in a dryer to obtain dry solids.

In the drying process, the heat and quality (moisture) transfer must be completed at the same time to ensure that the partial pressure (concentration) of the moisture vapor on the surface of the material is higher than the moisture vapor partial pressure in the external space, and ensure that the temperature of the heat source is higher than the temperature of the material.

The heat is transferred from the high temperature heat source to the wet material in various ways, so that the moisture on the surface of the material vaporizes and escapes to the outside space, so that the difference in moisture content appears on the surface and inside of the material. The internal moisture diffuses and vaporizes to the surface, so that the moisture content of the material is continuously reduced, and the overall drying of the material is gradually completed.
