摘要
对高大平房仓储存的小麦分别采用BT35—11NO.5.6普通型轴流式风机、CZLB—2.2S型可逆转式强力轴流式风机、4-7.2—11NO.6C型离心式风机进行通风降温,并对整仓平均粮温、分层平均粮温、分层粮食水分以及能量消耗等进行效果评价。结果表明在中央储备粮郑州直属库所处地区进行冬季通风降温,普通型0.55kW的轴流风机380～413小时可将高度6m的粮堆平均温度降到5℃左右,且能量消耗(0.025kW·h/℃·t)和粮食水分变化(小于0.2%)很小,离心风机(结合0.55kW的轴流风机)可在147小时将平均粮温降到3.5℃,降温速率较快,但能量消耗(0.081kW·h/℃·t)和粮食水分变化(0.7%)却比较大。
Three kinds of fans, including axial - flow machine of lower power（0.55kW）, axial - flow machine of higher power（2.2kW） and centrifugal fan of higher power（5.5kW） were compared in lowering temperature and moisture of wheat stored in four horizontal warehouses. The evaluation was done in average temperature and moisture content in shole bulk, top and bottom, and power consumption. The results showed that the axial fan（0. 55kW） can lower the temperature from 10℃ to 5℃ in 380- 413h for 6m - high grain bulk in winter in Zhengzhou area. Power consumption was 0. 025kW· h/℃, the moisture content chaged little（ 〈 0.2% ）. Centrifugal fan combined with axial fan（0.55kW） can lower grain temperature to 3.5℃ in 147h, it can lower temperature rapidly, but power consumption（0. 081kW· h/℃· t） and change of moisture content（0.7 % ） was bigger.
