Design of hot air drying for better foods - ScienceDirect
网页2006年4月1日 · Heat pump drying uses a refrigeration unit to heat and dehumidify the air, which circulates in the system. Control of air temperature and humidity results in a well-controlled drying system assuring required product quality. Heat pump drying can yield food with good quality at reduced energy consumption (Rossi, Neues, & Kicokbusch, 1992).
