浙江省地处东南沿海,属于亚热带温湿气候,每年有大批高水分粮要就地收购或从外省调运入库。为确保储粮安全,要花费大量财力和人力进行烘干整晒。但是,由于烘干设备、整晒场地和人力的不足,常使高水分粮处理工作处于被动局面。为改变这种状况,我们从七十年代中期就开展了大型房式仓储粮地槽机械通风降水试验,经过十多年 Zhejiang Province is located in the southeast coast of the subtropical climate is warm and humid, a large number of high-moisture food each year to be acquired on-site or transferred from other provinces warehousing. In order to ensure the safety of grain storage, we must spend a lot of money and manpower to dry the whole drying. However, due to lack of drying equipment, sun drying space and manpower, the processing of high-moisture food grains is often in a passive situation. In order to change this situation, we conducted a large-scale warehouse storage grain-trough mechanical ventilation and precipitation test since the mid-1970s. After more than a decade
