1、由于气温和粮温相差较大,第一次通风时间要选在白天,以减小粮温和气温的差距,减轻结露的发生。以后的通风尽量选在晚上进行,因为本次通风是以降温为主,晚上大气湿度相对偏高、温度较低,这样即减少了水份损耗,又充分利用了晚上的低温,提高了降温效果。
1, because of the large difference between temperature and grain temperature, the first ventilation time should be selected during the day to reduce the difference between grain and temperate air and reduce condensation. After the ventilation is chosen in the evening as far as possible, because the ventilation is mainly cooling, the air humidity is relatively high and low at night, which reduces the loss of water, and makes full use of the low temperature at night and improves the cooling effect.
2、用离心风机通风初期有可能会出现门窗、墙壁结露,甚至表层粮面轻微结露,只要停止风机,打开窗户,开启轴流风机,必要时翻动粮面,将仓内的湿热空气排除仓外就可以。而用轴流风机进行缓速通风就不会出现结露现象,只会出现中上层粮温缓慢上升,随着通风的继续进行粮温会平稳下降。
2, in the early stage of ventilation with centrifugal fans, there may be doors and windows, wall dew, even surface grain surface slight dew, as long as stop the fan, open the window, open the axial fan, when necessary to flip the grain surface, the hot and hot air inside the warehouse can be excluded out of the warehouse. When the axial fan is used for slow speed ventilation, the condensation phenomenon will not appear, only the grain temperature in the middle and upper layers will rise slowly. As the ventilation continues, the grain temperature will decline steadily.
3、用轴流风机进行缓速通风时,由于轴流风机的风量小,另外粮食是热的不良导体,通风初期容易出现个别部位通风缓慢,随着通风的继续进行全仓粮温会逐渐平衡。
3. When the axial fan is used for slow speed ventilation, because the air volume of the axial fan is small and the grain is a bad conductor of heat, the ventilation is easy to appear in the early stage of the ventilation. As the ventilation continues, the whole grain temperature will be gradually balanced.

4、进行缓速通风的粮食必须经过震动筛的清理,并且入到仓内的粮食必须及时清扫自动分级造成的杂质区,否则易造成局部通风不均。 5、能耗计算:14号仓用轴流风机累计通风50天,平均每天15小时,共用750小时,水份平均降了0.4%,粮温平均降了23.1度,单位能耗为:0.027kw.h/t.℃。28号仓累计通风6天,共用126小时,水份平均降了1.0%,温度平均降了20.3度,单位能耗0.038kw.h/t.℃。
4, the grain that carries on the slow speed ventilation must be cleaned by the vibrating screen, and the grain into the warehouse must be cleaned in time by the automatic classification of the impurity area, otherwise the local ventilation is easily unevenly. 5, energy consumption calculation: 14 warehouse with axial fan accumulative ventilation for 50 days, average 15 hours a day, sharing 750 hours, the average drop of water 0.4%, the average grain temperature dropped 23.1 degrees, unit energy consumption is 0.027kw.h/t. C. Warehouse No. 28 accumulated ventilation for 6 days, shared 126 hours, the average water decreased by 1%, the temperature decreased by 20.3 degrees, and the unit energy consumption was 0.038kw.h/t. degrees.
6、以轴流风机进行缓速通风的优点:降温效果良好;单位能耗低,在倡导节能的今天尤为重要;通风时机易掌握,不易出现结露;不用单独配备风机,方便灵活。缺点:由于风量小,通风时间长;降水效果不明显,高水份粮不宜用轴流风机进行通风。
6. The advantages of slow speed ventilation with axial fan: good cooling effect, low unit energy consumption, especially important in advocating energy saving today; ventilation time is easy to master, not easy to appear, and it is convenient and flexible. Disadvantages: because of small air volume and long ventilation time, the effect of precipitation is not obvious.
7、离心风机的优点:降温、降水效果明显,通风时间短; 缺点:单位能耗高;通风时机掌握不好易出现结露。
7, the advantages of centrifugal fan: cooling, precipitation effect is obvious, short ventilation time; shortcoming: high unit energy consumption; ventilation timing is not good, easy to appear condensation.
8、结论:在以降温为目的的通风中,应用轴流风机进行安全、高效、节能的缓速通风;在以降水为目的的通风中应用离心风机。
8. Conclusion: in the ventilation with the purpose of cooling, the axial fan is used for the safe, efficient and energy saving ventilation, and the centrifugal fan is applied to the ventilation for the purpose of precipitation.
