Research on the Techniques for Infrared Drying of Shiitake Mushroom

Abstract:

In order to obtain high-quality dried mushroom efficiently,this paper investigated the impact of infrared drying on the drying characteristics of shiitake mushrooms,and compared with hot air drying methods,analysis of the impact of two different drying methods on the products quality of dried shiitake mushroom.The results showed that Pre-drying,Gill-up position have higher dryi ng rate than cap-up position;As the temperature increases,the irradiation distance decreases,the loading coefficient decreases,the wind velocity increases,the time required for drying is gradually reduced.The products sensory and chemical quality dried by infrared is superior to hot air.
