Abstract


The principle of heat pump air control drying, tests of vegetable drying and their propotion were introduced on this paper. The systerm of heat pump with double condenser and double evaporater was used to complete the circulation of air in a drying machine and then a air control test machine was maded. Because of changing the conditional model of hot air drying machine in which of the fresh air was contineuly inhaled and wast gas was contineuly drianed away, the energy was saved.It is proved by air control drying tests that guality of dried vegetable was improved because of decresing O2 content in the aircontral drying. A box drying machine and a continued drying equipment were used to production with smal and large batch during the propition respectly. It is proved that the heat pump air contronled techniqul was suited for application. Instead of double condencer and double evaporate systerm A heat pump systerm with circulation water was used to continued air control equipmend and won good result.It is proved by aplication that 2 mesond of temperature and humidity have their characteristic which could be applicated aconding to production condition.
