Refrigeration dryer is a machine composed of refrigeration system, vacuum system, heating system and electrical instrument control system. The main components are drying oven, condenser, refrigeration device, etc. The refrigeration process is to freeze the water containing material into a solid state first, and then sublimate the water from the solid state. Enter the gaseous state to remove moisture and preserve the material. Now let's get to know it with Xiao Bian.
In the refrigeration system of the refrigeration dryer, the evaporator is a device used to transport cold energy, in which the refrigerant absorbs the heat of the compressed air to achieve the purpose of dehydration and drying. The compressor is the heart, which plays the role of inhaling, compressing and transmitting refrigerant vapor. The condenser is a heat generating device, which transfers the heat absorbed in the evaporator and the heat converted from the input power of the compressor to the cooling medium for removal. The expansion valve/throttle valve plays the role of throttling and depressurizing the refrigerant, controls and regulates the amount of refrigerant liquid flowing into the evaporator, and divides the system into two parts: the high-pressure side and the high-pressure side.
In the process of compressed air drying, freeze-drying is to reduce the temperature of the compressed air so that the water in the compressed air can precipitate. After the compressed air passes through the frozen compressed air pipe, the temperature of the compressed air drops to the required temperature and meets the drying requirements.
