一个办法就是在春季储粮时采取勤翻动粮面和加强仓门窗管理,在春季储粮要关闭好仓门、窗,不要随意打开,这样可以防止仓内粮食的上层结露。另一个办法就是对过冬储藏的粮堆进行通风,调节和均匀仓内粮温,消除温差,破坏仓内微气流循环。春季通风应选择在气温和气湿都较低的夜间进行。那么怎样利用有利条件进行适时通风呢?1.允许通风的温度条件。通风开始时的气温与粮温温差不小于8℃,通风进行时的温差不小于4℃。2.允许通风的湿度条件。由于所进行的通风不但要调节温差,同时经过通风也要降低仓内大水分区域的
One solution is to ground the grains and strengthen the management of the doors and windows in spring when they are stored in spring. In the spring, grain storage should be shut down to keep the doors and windows open. Do not open them at will. This will prevent the upper layer of grain from dew condensation. Another approach is to ventilate the grain piles stored during the winter to regulate and even grain temperature inside the warehouse to eliminate the temperature difference and damage the micro-circulation inside the warehouse. Spring ventilation should be selected in the temperature and humidity are lower at night. So how to use the favorable conditions for timely ventilation? 1. Permissible ventilation temperature conditions. Ventilation at the beginning of the temperature and food temperature difference of not less than 8 ℃, ventilation temperature difference of not less than 4 ℃. 2. Ventilation allowed humidity conditions. As the ventilation carried out not only to adjust the temperature, while also reducing the ventilation of the warehouse water area
