【Abstract】 In this paper, we carried out the experimental study on the heat transfer, preventing and cleaning fouls characteristics of the three-phase circulating fiuidized bed evaporator during condensing rhubarb liquid extract of Chinese traditional medicine, put forward the relationship of heat transfer coefficient. At the same time, we also studied flow characteristics of the three-phase. The results of study show that the vapor-liquid-solid three-phase circulating fiuidized bed evaporator will be used broadly during condensing liquid extract of Chinese traditional medicine in the future.更多还原
