Hopper Dryer

The dryer is a kind of mechanical equipment that uses heat energy to reduce the moisture content of materials. It is used to stop the drying operation of objects and vaporize the moisture (usually moisture or other volatile liquid components) in the materials after heating to obtain solid materials with regular moisture content. The purpose of drying is to meet the requirements of material application or further processing.

The future development of dryers will develop and improve dryers under the conditions of deepening the study of drying mechanism and material drying characteristics, and controlling the operation conditions of different materials; In addition, large-scale, high strength, high economy, and improved compliance with raw materials and quality are the fundamental trends of dryer development. Now let's introduce the function, working principle, classification, operating procedures, selection instructions and cleaning methods of the dryer.

The dryer acts as a refrigeration compressor to suck the low pressure (low temperature) refrigerant in the evaporator into the compressor cylinder. The refrigerant steam is compressed, and the pressure and temperature rise at the same time; The refrigerant steam with high pressure and high temperature is pressed to the condenser. In the condenser, the refrigerant steam with higher temperature and cooling water or air with lower temperature stop heat exchange.

The heat of the refrigerant is taken away by water or air and condensed, and the refrigerant vapor becomes liquid. This local liquid is then sent to the contraction valve, which is throttled into a low temperature and low pressure liquid and enters the evaporator; The low temperature and low pressure refrigerant liquid in the evaporator absorbs the heat of the compressed air and vaporizes (commonly known as "evaporation"), while the compressed air condenses a large amount of liquid water after cooling; The refrigerant steam in the evaporator is sucked away by the compressor.
