Abstract: We have studied nutritions degradation kinetics for evaporating concentration process in this paper, and set up thekinetics model of carotene loss during the process of evaporating pumpkin juice with circulating fluidized bed evaporator withthree-phase flow. Our experimental conclusion showed: The predicted values from the model agree very well with the measuredvalues, and this model has definite application values for industrial production.
