【中文摘要】 远红外定温干燥蘑菇的脱水过程分恒速和降速两阶段,物料温度分升温、稳定和再升温三阶段;干燥过程中恒速和降速两阶段的速率模型可分别为dM/dt=K_1(T-Tw)和dM/dt=K_2(M-M_e)表示。本文同时分析了平均脱水率与干后品质间的关系。

【英文摘要】 The dehydrating process of Agaricus bisporus drying at set temperature by far - infrared radiation can be divided into 2 stages of constant speed and reducing speed, while the mushroom temperature can be divided into 3 stages of rising temperature, stabilizing temperature and re- rising temperature. It was showed in our study that the speed models during dehydrating process could be expressed with the equations of dM/dt=K1(T-Tw) and dM/dt=K2 (M-Me). And the relationship between the average dehydrating rate and dried mushroom quality was also analyzed in this paper.
