摘　　要：粮食烘干机械采用的热源不同,其作业成本差异较大。选用生物质、柴油及蒸汽3种热源的低温循环式粮食烘干机,将初始含水率不同的稻谷烘干至安全储存含水率(15%),核算烘干作业能源成本。结果表明:每千克稻谷含水率下降1%,生物质热源烘干机作业平均能源成本为0.0042元/kg,柴油热源烘干机为0.0068元/kg,蒸汽热源烘干机为0.0021元/kg。The heat sources used in rice drying machinery is different,and the cost of operation varies greatly.In this experiment,select the low temperature circulating grain dryer of three heat sources,biomass,diesel fuel and steam,and dry the rice with different initial moisture content to the safe storage water content(15%),and account for the energy cost of the drying operation.The results showed that:The average moisture content per kilogram of rice decreased by 1%,the average energy cost of biomass heat source dryer was 0.0042 CNY/kg,the average energy cost of diesel heat source dryer was 0.0068 CNY/kg,and the average energy cost of steam heat source dryer was 0.0021 CNY/kg.
