| Abstract: | Vapor-liquid-solid three-phase circulating fluidized bed evaporator was employed condense pumpkin juice according to the structure and characteristics of it.Effect of inertia particle motion on heat transfer of condensing pumpkin juice in circulation fluidized bed was discussed, heat transfer model was put forward as well. Experimental results indicated that the experimental value was in good agreement with the theoretical value. |
