Twesix grain drying machine, equipped with heat pump dehydrator, is a new generationof environmental protection and energy saving equipment. The grain dryer is driven by electricity, using high temperature refrigerant to circulate continuouslyto release the heat, and the heat exchanger will absorb the heat from the air and deliver the heated air in high temperature to drying tower. Input one portion of electricity energy, and you will get 3-5times of heat to dry grain.So compared with traditional grain dryer powered by electricity or gas, the heat pump paddy dryer can save 60 to 70% energy. For large grain coporations, we design grain tower dryer with heat pump dehydrator,which can dry hundred tons per day.For small or medium farms, we designed cabinet grain dryer powered by heat pump dryer,which can process 500kg to 10000kgs per day.
