立筒仓谷冷通风及机械通风综合应用

Comprehensive Application of Cold Ventilation and Mechanical Ventilation in Vertical Silo

针对华南地区立筒仓夏季高温季节玉米下层及中上层发热情况,结合离心风机负压通风及谷冷通风综合应用,可有效解决立筒仓夏季玉米发热问题,并将玉米最高粮温控制在32℃以下,平均粮温控制在25℃以下,对延缓玉米品质劣变、保证玉米储存安全具有重要意义。

Aiming at the heat generation of the lower and middle and upper layers of corn in the vertical silo in summer in South China,combined with the comprehensive application of centrifugal fan negative pressure ventilation and valley cooling ventilation,it can effectively solve the problem of corn heating in the vertical silo in summer.Controlling the maximum corn grain temperature below 32℃and the average grain temperature below 25℃is of great significance to delaying the deterioration of corn quality and ensuring the safety of corn storage.
