哈尔滨香坊粮库的10个大型钢板仓,过去由于缺少机械通风降温系统,发生过多起霉变坏粮事故,造成了严重的经济损失。为了确保安全储粮,我们于1996年设计安装了小麦钢板仓机械通风降温系统,应用后效果显著。 一、目的 粮食在储存过程中对水分、温度和空气非常敏感,低温时处于休眠状态,高温时发生霉变;小麦在安全水分(≤13.5)条件下保持活力的最高温度为20～28℃。设计小麦钢板仓机械通风系统的主要目的是通风调温,延缓粮食陈化;通风降温,抑制害虫繁殖,灭菌杀虫;通风调温调湿,防止结露结顶。
Ten large steel silos in the Xiangfang Grain Store of Harbin have caused serious economic losses due to the excessive number of moldy and bad food accidents due to the lack of a mechanical ventilation cooling system. In order to ensure safe grain storage, we designed and installed a mechanical ventilation and cooling system for wheat silos in 1996, which has a significant effect after application. I. Purpose Grains are very sensitive to moisture, temperature and air during storage. They are dormant at low temperatures and mildew at high temperatures. The maximum temperature for wheat to maintain vigor under safe moisture (≤ 13.5) is 20 to 28°C. The main purpose of the design of wheat silo mechanical ventilation system is ventilation and temperature control, delay grain aging; ventilation and cooling, inhibition of pest breeding, sterilization and insecticide; ventilation and conditioning temperature and humidity, prevent condensation and top.
