The U.S. Department of Energy's Office of Scientific and Technical Information. Heat pump is special suitable to dry sensitive materials like fruits and vegetable in accordance with settled different drying curve. Heat pump drying is a low temperature drying process, the heat pump dryer can control the drying chamber temperature between ℃.

China new technology industrial air source Heat Pump Food dehydrator/Dryer/drying machine. Brief introduction. ORHGC series hot air circulation oven adopts noise elimination and thermal stable axial flow fan and automatic temperature control system. The successful designmakes the heat efficiency increases from 3~7% of the traditional drying oven to 35~45% of the present one.   Explore the Social, Technological, and Economic Impact of Heat Pump DryingHeat pump drying is a green technology that aligns with current energy, quality, and environmental concerns, and when compared to conventional drying, delivers similar quality at a lower cost. Heat Pump Dryers: Theory, Design and Industrial Applications details the progressioCited by: 2.

  For the better result, Cartwright described the modelling of the heat pump assisted dryer and Baines and Carrington conducted a simulation analysis where they were studied different configurations and the effects of modifications of basic the heat pump assisted drying process two component viz., the heat pump and the actual drying material, treated separately (Alves-Felho et Cited by: realized in the heat pump. Temperature lift is the difference between the evaporator and condenser temperatures. Figure illustrates how the cost of heat delivered by an electric-motor-driven mechanical heat pump depends on the cost of electric power and on the temperature lift that the heat pump achieves.
