为了解决目前黑木耳机械化干制中采用恒温恒湿热风干燥工艺存在的木耳干燥速率高,但存在收缩不充分、叶片不平整或破碎、表面色泽灰暗或无光泽等外形较差的问题,本文通过对黑木耳恒温恒湿热风干燥特性和品质变化的分析,提出了黑木耳四阶段变温调湿干燥制度,并进行了实验和烘房生产实验验证,得到的黑木耳外形、多糖含量和干湿比接近自然晾晒品质.变温调湿热风干制黑木耳的方法为产地烘房烘干黑木耳提供了参考工艺.
為瞭解決目前黑木耳機械化榦製中採用恆溫恆濕熱風榦燥工藝存在的木耳榦燥速率高,但存在收縮不充分、葉片不平整或破碎、錶麵色澤灰暗或無光澤等外形較差的問題,本文通過對黑木耳恆溫恆濕熱風榦燥特性和品質變化的分析,提齣瞭黑木耳四階段變溫調濕榦燥製度,併進行瞭實驗和烘房生產實驗驗證,得到的黑木耳外形、多糖含量和榦濕比接近自然晾曬品質.變溫調濕熱風榦製黑木耳的方法為產地烘房烘榦黑木耳提供瞭參攷工藝.

In this paper,the hot air drying characteristics of Auricularia auricula and its product quality were analyzed un-der constant drying air temperature and humidity. Although this way of drying is fast,there are problems of poor appearance, such as not sufficient shrinkage,uneven or broken blades,color gray or matte surface. To further improve the drying quality, a four-stage varying temperature and humidity drying schedule was proposed and two drying system were applied tothe hot air drying of Auricularia auricula using laboratory-scale and pilot intelligent drying rooms. In both tests,the appearance,the polysaccharide content and the wet/dry weight ratio of the dry products were close to the sun-dried ones,but the drying time was shorter. The research results provide some guidelines on drying room drying of Auricularia auricula in the production place.
