摘　　要：2017年4月13日-6月16日,在山东省军粮储备库13号房式仓(粳稻谷2 489t,水分13.5%)采用2台0.85kW轴流风机上行吸出自然空气进行智能化调质通风,平均粮堆水分增加了0.5%,风机运转333h,用电566.1k W·h,单位能耗0.455k W·h(1%·t)^(-1)。通风后整仓粮堆整精米率为71.7%,比调质前提高3%,籽粒破损率为7.7%,上下4层水分分布均匀,无水分迁移现象发生。An intellectualized grain bulk detection, aeration window controlling, and CAE equilibrium moisture equation of paddy were used to instruct aeration. Combined the intelligent detection technology with ventilation window control model, the ventilation window region for increasing grain moisture was constructed according to the principle of controlling aeration by paddy CAE equation,the equilibrium adsorption absolute humidity curve of paddy and air saturated humidity curve. The ventilator turned on when the air status point within the window region, turned off when outside. During April 13th, 2017 to June 16th, 2017, the system was used for a paddy depot of 2 489 t in Shandong Grain Reserve Depot for Army Provision in Qihe, China and increased grain moisture of 0.5 percent within the accumulated 566.1 kW of power consumption with two 0.85 kW-power axial flow fans. The unit energy consumption was 0.455 kW·h(1%·t)-1. The percent of average head rice yield and cracked/broken grains in the whole depot after aeration was 71.7% and 7.7%, respectively, with even moisture distribution in the whole paddy bulk.
