【摘要】 为研究异形竖板降膜蒸发器浓缩蔬菜汁时蒸发温度对品质的影响,对蒸发浓缩过程中营养损失动力学进行分析研究,结合Arrhenius模型、Z值模型、H-E模型,建立蒸发浓缩果蔬汁时营养损失的新的动力学模型;同时给出反应级数的精确计算方法。更多还原

【Abstract】 In effort to investigate influence of evaporation temperature on the quality during the concentration process of vegetable juice with dimpled vertical plate falling film evaporator, we have studied nutrition degradation kinetics for evaporating concentration process in this paper, and established the kinetics model of nutrition loss during the process of evaporating vegetable juice with Arrhenius model, z model and H-E model. And proposed precise calculating method of reaction series.更多还原
