What are the common drying methods?
In the actual production process, for high-humidity materials are generally as much as possible first with mechanical dehydration method to remove a large number of free water, and then take other drying methods for drying.
Is the use of moisture to remove gas, liquid, solid material in a small amount of water, due to moisture dehumidifier dehumidification capacity is limited, only used to remove trace moisture in the material, so the production of very little.
heating and drying method
Mechanical dehydration method is through the way of the material pressure, will be part of the water extrusion. Commonly used in pressing, sedimentation, filtration, centrifugal separation and other methods. Mechanical dehydration method can only remove part of the material free water, combined with water remains Material, so the material after the mechanical dehydration of the material moisture content is still high, generally 40 to 60%, but the mechanical dehydration method is one of the most economical method.
Drying method Drying is the process of removing moisture from various materials. Various materials can be solid, liquid or gas, solid and can be divided into large pieces of material, fiber material, pellets, fine powder and so on, Is the moisture in the material, it can be other solvents. In this water for the object. Drying equipment, there are three ways to dry: (1) mechanical dehydration
