协同加热除湿烘干机设计及对香菇烘干性能的测试
Design of drying machine with co-heating and dehumidification and testing of its drying performance on shiitake mushrooms
摘要
Abstract
Objective:In order to improve the mushroom drying efficiency and reduce the power consumption,a new type of co-heating and dehumidification drying machine was designed and built.Methods:The drying machine was a closed system,which took the semiconductor refrigeration piece as the main component,with its hot end as heat source for air pre-heating and its cold end as the cold source for water vapor condensation.On the device,the mushroom drying rate at different drying temperatures(55 and 65 ℃)and sample mass(200 and 400 g)were tested.Results:Nine thin layer mathematical drying models were used to simulate the drying rate,which revealed that the Midilli model had a better predict effect than the others.In addition,it was found that the higher drying temperature resulted in a greater color change and a higher shrinkage rate.The comprehensive energy efficiency ratio of the drying machine was 1.96,and the power consumption of drying mushroom was 81.21 MJ/kg.Conclusion:In the experiment,the indexes such as moisture content and color change of dried mushroom met the national standards,and the energy-saving effect was remarkable compared with the traditional electric heating drying machine.关键词
