高大平房仓智能膜下环流及开放环流控温试验

Antibacterial activity of intelligent membrane under the circulation and open the test of temperature control

经过在高大平房仓两个试验仓一个储粮周期的膜下环流控温试验,效果非常理想,最高粮温控制在20℃以下,表层30 cm粮温在22℃以下,底层粮温没有超过10℃。由于试验仓可同时进行自动排积热和自动环流通风,具备了不用粮面覆膜和预埋回流管而采用开放环流控温的基本条件并进行试验,效果同样好,同时具有施工方便,劳动量小,改造成本低,易于推广的特点。

After the antibacterial activity of two experiments of grain storage ware- house a cycle under the membrane of circulation temperature control experiment, the ef- fect is very ideal, the highest grain temperature control at 20 ~C below, the surface temper- ature under 22 %, 30 cm food underlying grain temperature does not exceed 10 %. Be- cause of its warehouse at the same time of automatic exhaust heat and automatic circula- tion ventilation, have not USES surface coated and buries the return line and using open circulation temperature control, the experiments of basic conditions and effect also good, at the same time has the construction is convenient, small amount of labor, the cost is low, the characteristics of easy to promote.
