金耳烘干箱烘干效率测定

Determination of Drying Efficiency of tremella Aurantialba Drying Box

金耳是一种稀有的胶体食用菌,被誉为“真菌皇后”。由于天气和储存条件的问题,金耳在运输和储存过程中常常会发生霉变,因此常常会对新鲜金耳进行烘干。本文利用福建古田金耳、双耳菌菇合作社的AXR-101型热泵烘干箱进行实验,对左侧烘干室内15层物料托盘进行了实验,烘干时长为20 h,每隔2 h对质量进行测量。结果表明烘干箱上下层烘干效率存在明显差异,烘干室上层的烘干效率范围在6.1%~22.6%,下层的烘干效率范围在0~39.6%,上层的烘干效率在0~8 h内烘干效率逐渐降低,在8~12 h内有小幅度上升,之后随之减小,下层的烘干效率呈现下降趋势,仅在6~14 h中呈现了烘干效率保持的趋势。

Golden fungus is a rare colloidal edible fungus known as the"queen of fungi".Due to weather and storage conditions,it is common for the fungus to become mildew during transportation and storage,so fresh fungus is often dried.In this paper,the AXR-101 heat pump drying box of Fujian Gutian Golden Fungus and Amphora Mushroom Cooperative was used to conduct experiments on the 15-layer material tray in the left drying room,and the drying time was 20 hours,and the quality was measured every 2 hours.The results showed that there was a significant difference in the drying efficiency of the upper and lower layers of the drying chamber,the drying efficiency of the upper layer of the drying chamber ranged from 6.1%~22.6%,the drying efficiency of the lower layer ranged from 0~39.6%,the drying efficiency of the upper layer gradually decreased within 0~8 hours,increased slightly within 8~12 hours,and then decreased,and the drying efficiency of the lower layer showed a downward trend,and only had a trend of drying efficiency maintenance in 6~14 hours.
