The working principle of the dryer
Freeze dryer is the use of this principle using refrigeration technology to dry compressed air.
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 to reduce the water vapor content in the compressed air while maintaining the compressed air pressure substantially constant, and the excess water vapor will condense
As the natural drying can not meet the needs of the development of production, a variety of mechanized dryer more and more widely applied.
Another dry material is also easy to transport and storage, such as the harvest of food to a certain moisture content below, to prevent mildew.
Such as wood in the production of wood mold, wood drying can prevent the deformation of the product, ceramic billet in the calcination before drying can prevent the finished product cracking.
