华南生态储粮区楼房仓常规储藏仓温粮温变化规律研究

Grain Temperature Change Law of Multi-storied Warehouse in South China

对华南地区楼房仓在常规储藏稻谷期间的仓温、粮温变化规律进行研究,分析对比了不同楼房仓、不同栋仓、不同季节粮温、仓温变化的差别。结果表明:每年的9月到次年的3月,楼房仓的粮温高于仓温,最高值高于仓温4.7℃;而每年4月到9月,楼房仓的仓温高于粮温,最高值高于粮温3.2℃;同一栋楼房仓不同楼层的仓房,在春夏季节中的粮温表现为:上层仓房>中层仓房>下层仓房,在秋冬季节中的粮温表现为:中层仓房>下层仓房>上层仓房;不同栋楼房仓相同楼层的仓房温度变化趋势相同。

In south China,we conduct an experiment on the variation of grain storage-temperature in the conventional storage of Multi-storied warehouse,which analyzed and compared the difference of the grain temperature and tank temperature in different warehouse, on different floors and in different seasons. The results showed that： During September and March in the following year, the grain temperature is higher than the tank temperature;During April and September,the tank temperature is higher than the grain temperature. The different floor in a Multi-storied warehouse has a different grain temperature in different seasons,in the spring and summer,the temperature of the Multi-storied warehouse from high to low followed by upper barn, middle barn, lower barn.In fall and winter, the temperature from high to low followed by middle barn, lower barn, upper barn. The multi-storied warehouse on the same floor has a similar trend.With the conventional technique of grain.
