The ginger garlic heat pump dryer machine is essentially a heat lifting device. The high-temperature heat pump drying unit uses the reverse Carnot principle to absorb heat from the surrounding environment and transfer it to the raw ginger or garlic to be heated.
Advantages of ginger garlic heat pump dryer equipment:
♥ It can realize low-temperature air closed circulation drying, and the material drying quality is good. By controlling the working conditions of the device, the temperature of the hot dry air in the drying chamber is between 20 and 80°C, which can meet the high-quality drying requirements of most heat-sensitive materials; the closed circulation of the drying medium can avoid the exchange with the outside air. Possibly contaminated materials by impurities, which is especially important for food, medicine or biological products. In addition, when the material is sensitive to oxygen in the air (easy to oxidize or burn and explode), an inert medium can be used instead of air as the drying medium to achieve oxygen-free drying.
♥ High efficiency and energy saving. The heat of the heated air in the heat pump dryer mainly comes from the sensible heat and latent heat contained in the warm and humid air discharged from the recovery drying chamber. The energy that needs to be input is only the power consumption of the heat pump compressor, and the heat pump consumes a small amount of power to produce The advantage of taking a lot of heat, so the heat pump drying device SMER (the water content in the wet material removed by the unit of energy consumption) is usually 1.0 ~ 4.0 kg/kWh, while the SMER value of the traditional convection dryer is about 0.2 ~ 0.6 kg/kWh.
♥ Convenient temperature and humidity control. When the material has high requirements for the temperature and humidity of the air entering the drying room (such as wood, etc.), the evaporation temperature and condensation temperature of the working fluid in the evaporator and condenser can be adjusted to meet the material's texture and appearance. Require.
♥Useful and volatile components in recyclable materials. Some materials contain volatile components (such as fragrance and other volatile components). When the heat pump is used for drying, the volatile components and water vaporize into the air together in the drying room, and the air containing volatile components passes through the evaporator. When it is cooled, the volatile components are also liquefied and discharged together with the condensed water. Collect the condensed water containing the volatile components and separate the useful volatile components by appropriate methods. Video:
Application of heat pump ginger drying machine:
The heat pump ginger garlic dryer is suitable for a wide range of materials. The materials suitable for drying are mainly a large class of materials that can withstand temperatures between 20 and 80 ℃ during the drying process, or materials that can withstand higher temperatures but are more energy-saving or safer by heat pump drying.
Materials that have been studied and applied more such as fruit or vegetables like apple, peach, berries, leaves, onion, grains, seeds, mushrooms, fungus, medicinal materials (such as ginseng, etc.), seafood (such as fresh oysters, scallops, etc.)
→ Low energy consumption: Heat pump drying technology has the advantages of low energy consumption, low environmental pollution, high drying quality, and wide application range. Its excellent energy-saving effect has been proved by various experimental research institutes at home and abroad. →Environmentally friendly: The drying medium in the heat pump drying device circulates in a closed loop, and there is no pollution caused by material dust, volatile substances and peculiar smells discharged into the environment with the drying exhaust gas; the waste heat in the exhaust gas of the drying chamber is directly recovered by the heat pump to heat the cold and dry air. Thermal pollution of the unit to the environment.
