How the air dryer works
working principle
For example, the drying of the wood before the production of the wood mold and the wood can prevent the deformation of the product, and the drying of the ceramic material before the calcination can prevent the product from cracking. In addition, the dried material is also convenient for transportation and storage, such as drying the harvested food to a certain moisture content to prevent mildew. Since natural drying is far from meeting the needs of production development, various mechanized dryers are becoming more and more widely used.
The amount of water vapor in the compressed air is determined by the temperature of the compressed air: reducing the temperature of the compressed air reduces the amount of water vapor in the compressed air while maintaining the constant pressure of the compressed air, and the excess water vapor condenses. Into a liquid. The freeze dryer uses this principle to use refrigeration technology to dry compressed air. Therefore, the dryer has a refrigeration system.
