Ⅰ,Introduction to heat pump drying unit
1. working principle of heat pump drying unit:
Heat pump drying units, mainly finned evaporator, compressor, fin condenser and throttle valve of four parts, by making the working medium is complete evaporation absorbs the outdoor environment (water vapor inside the dryer or heat) to compression, condensation (gives off heat drying room) indoors to throttle, thermodynamic cycle process of evaporation, again to the external environment at low temperature (or steam) inside the dryer or heat transfer to the drying room, under the action of refrigerant in the compressor circulating in the system. It made within the compressor gas booster heating process (temperature up to 100 ℃), it enters the release of the high-temperature heat drying room air, while being cooled and translated into flow liquid when it runs to the outside machine, rapid heat evaporating liquid into a gas again, at the same time, the temperature can fall to - 20 ℃ ~ 30 ℃, then the air surrounding the heat absorber will continue to transfer heat to the refrigerant.
Heat pump drying units at work, with the ordinary air conditioning, QA: medium in the evaporator absorbs the energy itself is part of the energy consumption, the compressor power consumption QB: through working medium circulation system in the condenser heat QC and QA + QC = QB, therefore the efficiency of the heat pump drying units for (QB + QC)/QB, so the heat pump drying units heat efficiency than other heating equipment efficiency, it can be seen that the heat pump drying units as drying device can save energy, no emissions of CO2 and other pollutants, at the same time, achieve the effect of energy conservation and emissions reduction.
2, Use place of heat pump dryer:
Heat pump drying units is applicable products, dehydrated vegetables, black and white fungus, melon seeds, peanuts, fruits and vegetables, meat products, casing, tobacco, leather, mushrooms, Chinese wolfberry, dried fruit, mosquito-repellent incense, GongXiang, fabrics, clothing, food grains, noodles, bean curd stick, fertilizer, medicine, traditional Chinese medicinal materials, paper, wood, seeds, sludge, gypsum, hardware products, metallurgical products, mining products, chemical products, flue gas desulfurization gypsum, clay, grass, flue-cured tobacco, pulverized coal, the coal and lignite drying.
3,Three: heat pump drying equipment features:
a, Dehumidification, drying, refrigeration, dehumidification, ventilation and ventilation are integrated intelligent drying and dehumidification equipment.
b, Easy to use, closed dehumidification and heat pump drying method are adopted to save energy and reduce emission. Compared with the traditional belt type hot air dryer, the energy saving is more than 40% and that of the microwave belt type dryer is more than 60%.
c, Suitable for all kinds of drying under 70 ℃ temperature desiccant dehydration mode, dry and stable, good quality, health.
d, The unit automatically adjusts the drying time and temperature according to the requirements of multi-temperature drying process, and intelligently controls the temperature and humidity curve program.
e, Meet the requirements of large temperature difference and gradient temperature pipeline drying process.
