长期以来,我国以房式仓储粮为主,缺乏筒仓储粮经验,建成的筒仓缺乏必备的储粮设施,一旦粮食发热、结露、生虫,只有依靠筒仓倒仓系统进行倒仓,给筒仓安全储粮带来一定的困难,同时也增加了储粮费用。为解决上述问题,有必要对筒仓储粮技术进行研究,以完善筒仓储粮的配套设施。本文仅讨论筒仓的通风降温系统。 1 筒仓增设通风降温设施的必要性 筒仓直径小且筒壁薄,筒内粮食易受环境温、湿度影响,筒壁及表层处的粮温变化幅度较大,加之粮食是热的不良导体,积 For a long time, our country has mainly warehouse-type grain storage, lack of silo grain storage experience, the lack of the necessary silos built grain storage facilities, once the food fever, condensation, parasites, , To the silo safe storage of grain to bring some difficulties, but also increased the cost of grain storage. In order to solve the above problems, it is necessary to study the silo grain storage technology to improve the silo grain storage facilities. This article discusses only the silo ventilation cooling system. 1 silos additional ventilation cooling facilities necessity Silo small diameter and thin wall, the barrel of food susceptible to environmental temperature and humidity, the wall and the surface of the grain temperature range, coupled with the food is poor heat conductor ,product
