一、概述我国的粮食仓库,散堆粮食的安全检查、检验样品的取样,一直都是用五十年代初期中粮部发下的“套筒九孔扦样器”取样。这种扦样器,头部尖咀有160毫米长度。对粮堆最底层的160毫米厚度的粮食,长期以来无法查清有无霉变事故,只有待出仓完了时才能发现。是粮食保管工作上二十多年来没有解决的问题。 First, an overview of China’s grain storage, bulk food security inspection, sample inspection samples, has been used in the early 1950s issued by the COFCO “Sleeve nine hole sampler” sampling. This shaver, the tip of the head has a length of 160 mm. It has long been impossible to detect the occurrence of mildew on the lowest 160 mm of foodstuffs, and it can not be detected until the warehouse is over. It is an issue that has not been solved for more than two decades in food preservation work.
