平行送风食用菌干燥装置效益分析

Benefits Analysis of a Parallel Air Supply Drying Device for Mushroom

提出了一种平行送风食用菌干燥装置,并与传统干燥方式对比,进行效益计算.本装置采用梯级加热模式,通过平行送风、太阳能预热和同步热泵的引用降低装置能耗,提高效益.以香菇干燥为例,本装置与普通热泵干燥及传统燃煤干燥相比,能耗之比为0.42∶0.67∶1,CO2、NOx、SOx排放之比为0.42∶0.67∶1,运行维护费之比为0.93∶1.35∶1.

In this paper,one kind of parallel air supply drying mushroom-type device is presented and benefits calculation is put forward by comparing with the traditional drying methods. The method of step-by-step heating technology is adopted,using solar to preheat,synchronous pump to heat and auxiliary electricity to finish heating so that the energy consumption can be reduced,which effectively increases benefits. The paper takes shiitake fungus for example,compares with the conventional heat pump and coal-fired drying,the ratios of this kind of device and the former one is presented,of which energy consumption is 0. 42∶0. 67∶1,emissions of CO2、NOx、SOx is 0. 42∶0. 67∶1 and operation and maintenance costs is 0. 93∶1. 35∶1.
