A heat pump system for Lentinula edodes drying and its drying property

Abstract

The traditional drying of Lentinula edodes is by hot gases obtained by burning coal or wood. This process wastes a lot of energy, increases carbon emissions, and rises the burden of the environment. This article presents a heat pump system for Lentinula edodes drying. Optimal conditions for drying process is obtained by using orthogonal test. Experiment results show that the heat pump system is reasonable, reliable, and practicable. Optimal drying process, compared to the traditional one, significantly improvs the drying quality
