建 立了远红外辐射 并配以排湿气流干 燥切片蘑 菇时有关 质热参数 模型，分析了 干燥中辐 射强化系数 Ｋ１ ，对流传质汽化系数 Ｋｔ ，总换热系数 α０ 和辐射换热系 数 α Ｅ 等 的变化规律⒚结果表 明，干燥温度和蘑菇含水率的不同，导致 Ｋ １ ， Ｋ１ Ｋ ｔ，α０ ，α Ｅ 等值也不同⒚ The model of heat and mass was established when the far-infrared radiation was set up and combined with the moisture-removing airflow to dry sliced ​​mushrooms. The radiation enhancement coefficient K1, convective mass transfer coefficient Kt, total heat transfer coefficient α0 and radiation heat transfer coefficient α E were analyzed. The results showed that the difference of K 1, K 1 K t, α 0, α E and so on due to the different drying temperature and mushroom moisture
