【摘要】 为了研究喷水率对真空冷却蔬菜的影响,本文选取叶菜类有代表性的茼蒿在自行设计的装置中进行了真空冷却实验,考察了不同喷水率对相对能耗、降温速率和失水率的影响。结果表明,采用高喷水率时,真空冷却过程中的相对能耗较少,降温速率较快,失水率较低。更多还原

【Abstract】 ln order to study the effect of water suppliment in vegetable vacuum cooling, crown daisy -a representative leaf -vegetable were chosen as experimental object to study the effect of water suppliment on relative energy, cooling rate and water decreasing rate in the vacuum cooling equipment. Low relative energy cost, high cooling rate and low water losing rate were found with high water suppliment ratio.更多还原
