| Abstract: | In this paper, we studied the heat transfer characteristics of three-phase circulating fluidized bed evaporator and the prevention and cleaning of fouling during the process of condensing pumpkin juice. We analyzed heat transfer properties of this type of equipment in some main operational conditions, established the correlation equation, and evaluated the quality of pumpkin juice during concentrating process. Experimental results showed that three-phase circulating fluidized bed evaporator had good heat transfer coefficient, resisted fouling, and allowed easy cleaning. This type of evaporator fits concentration of pumpkin juice and will be a encouraging alternative for food industry in the future. |
