Let’s discuss the issue of solid drying
Hot air drying, cold air cooling, vibrating fluidized bed drying unit.
Drying is a process in which moisture or other solvents are vaporized using heat, and the resulting vapor is removed, thereby eliminating the moisture from the solid material. Classification of drying processes: Based on operating pressure, it can be divided into atmospheric drying and vacuum drying ； Based on the mode of operation, they can be divided into continuous and batch types ； Based on the heat transfer mechanism, it can be divided into conduction drying, convection drying, radiation drying, dielectric heating drying, and combinations of two or more of these methods.
There are two forms of moisture in solids: one is attached to their surface and can be removed using ordinary mechanical methods； ； Another option is to dissolve into the interior of a solid! This is relatively difficult to remove
