在储藏小麦的高大平房仓中,根据计算机测温系统测出的一年中粮温、仓温以及同时间温度计检测的仓外气温为基本参考数据,分析了气温、仓温、全仓平均粮温、各层平均粮温、4个方向平均粮温和各区域平均粮温的年变化规律。分析结果表明:正常情况下,气温影响仓温,仓温影响粮温。年变振幅:气温>仓温,仓温>粮温;仓温滞后气温,粮温滞后仓温。上层平均粮温受气温影响最大,中下层最小;各层平均粮温受气温影响大小为上层>中上层>下层>中下层。四周平均粮温随季节变化明显。东侧平均粮温一年中波动幅度最小。外围平均粮温受外界条件如日照、气温等影响很大,其次为中央区域,中环区域波动最小。区域测温点温度在方向分布上有很大差异,分析时所用数据为区域平均值,因此粮温曲线不能正确的完全反映区域变化。所以有待进一步对区域的划分进行科学的改进。
In the storage of high-quality wheat warehouse, based on the computer temperature measurement system measured in the year grain temperature, temperature and warehouse temperature during the same time as the basic reference temperature data for the analysis of the temperature, warehouse temperature, the whole grain average temperature , The average grain temperature in each layer, the average grain temperature in four directions and the average grain temperature in each region. Analysis results show that: under normal circumstances, the temperature impact warehouse temperature, temperature warehouse temperature. Annual variable amplitude: temperature> warehouse temperature, warehouse temperature> food temperature; warehouse temperature lag temperature, grain temperature lag warehouse temperature. The average grain temperature of the upper layer was the most affected by the temperature, while the middle and lower layers were the least. The average grain temperature of each layer was affected by the temperature of upper layer> middle layer> lower layer> middle layer and lower layer. The average grain temperature around the obvious changes with the seasons. The average grain temperature on the east fluctuates the least in one year. The average grain temperature of the periphery is greatly affected by external conditions such as sunshine and temperature, followed by the central region and the smallest fluctuation in the Central region. The distribution of temperature in the region has a great difference in the direction of the distribution. The data used in the analysis is the regional average, therefore, the grain temperature curve can not accurately reflect the regional changes completely. Therefore, the division of the region needs to be further improved scientifically.
