摘　　要：热泵干燥技术已广泛应用于各个行业,但在食品工业中的应用还是十分有限的。和传统的热风对流干燥相比,热泵除湿应用于食品的干燥有明显的优点,主要表现为:节约能源、产品质量高、不受天气条件的影响等;另外,热泵干燥技术对环境有益,无废气排放。Heat pump-assisted drying has been used extensively in industries, but using for drying of foods has been limited. This paper describes the potential of heat pump dryers in food drying. Heat pump dryers offer several advantages over conventional hot-air dryers for the drying of food products, including higher energy efficiency, better product quality and the ability to operate independently of outside ambient weather condition. In addition, this technology is environmentally friendly in that gases and fumes are not given off into the atmosphere.
