| Abstract: | Low-temperature heat pump dryers are widely needed in drying of chemical products,foods,medicines and agricultural products.Three kinds of low-temperature heat pump dryers known as basic type,vacuum type and adsorbent type are introduced,and their structures,working principles and characteristics are briefly analyzed.It shows that the basic type low-temperature heat pump dryers has the least initial cost while the vacuum type has the most,and the vacuum type low-temperature heat pump dryers has the highest energy efficiency while the basic type has the lowest,the adsorbent type low-temperature heat pump dryers are moderate both in initial cost and energy efficiency.The above results could provide good reference for the design of low-temperature heat pump dryers. |
