Pepper drying room is good to pay more attention to these aspects. (1) Temperature requirements. First, the temperature range of the drying chamber: Drying chamber is 40-130 ℃ temperature range, different heating mode and different types of dry material at different levels to the influence of the temperature of drying chamber, such as using electric heating drying room temperature can reach 130 ℃, the air can heat pump heating drying room temperature can reach 80 ℃, using coal heat drying room temperature can reach 200 ℃, when the choice must pay attention to the above points, In addition, the temperature accuracy of the drying chamber should be plus or minus 5℃. The temperature in the baking room should be uniform, and the temperature should be constant throughout the room. The hot pepper drying room heats up fast, the requirement reaches the set temperature range within 1 hour. The drying chamber should be cooled quickly and should reach room temperature within 1 hour. The hot pepper drying room has good heat preservation performance. The heat preservation performance of the hot pepper drying room mainly depends on the design of the insulation layer of the drying room and the room body material […]
Chrysanthemum drying room, active temperature control, save time and labor. The principle is as follows: 1. The heating principle of the drying room: The heating mechanism of the drying house is hot. And the heat in the air is sent into the drying room by the fan. In the process of drying, the inlet is equipped with a temperature detector, and the operation of the heat pump host can be actively controlled according to the inlet temperature. When the temperature of hot air in the air inlet is lower than the set temperature (e.g., 60 degrees), the heat pump host starts to operate and add hot air supply to satisfy the dry demand of materials. Usually, the early stage is the heating time, and the late stage is the heat preservation time. When the temperature of the hot air in the air inlet reaches the set temperature (such as 70 degrees), the heat pump main engine stops operation, the lower the temperature requirement of the drying room, the longer the heat preservation time, so as to achieve the role of energy saving. 2, drying room humidity principle: Drying room humidity system, by the heat pump drying system active control. When […]
Chrysanthemum drying room is mainly used for drying machines. Also called air dryer is through heat pump, will be placed in the relatively closed insulation board room, through closed dry air circulation to condense water vapor on the cold sheet and discharge the board room, to achieve the intention of dehumidification and boring. Drying room working principle: (1) Compression process: Low temperature and low pressure refrigerant gas is compressed into high temperature and high pressure gas by the compressor. At this moment, the work done by the compressor is converted into the internal energy of the refrigerant gas, which increases the temperature and pressure, and is called an adiabatic process in thermodynamics. (2) Condensation process: The high temperature and high pressure refrigerant gas from the compressor flows through the condenser. It uses the wind or water to continuously release heat to the outside world. Condenses into medium temperature and high pressure refrigerant liquid. When the refrigerant is liquefied, the temperature drops but the pressure remains the same, which is called isobaric process in thermodynamics. (3) Saving process: The medium temperature and high pressure refrigerant liquid from the condenser becomes low temperature and low pressure refrigerant liquid by saving the equipment. […]
