一、前言粮食在储藏期间,由于粮食和有机杂质(植物的根、茎、叶等等),以及粮堆内的害虫和微生物的新陈代谢作用,会产生热量.粮食和有机杂质及虫、霉由于受到储藏条件(例如环境温度、湿度,粮食本身的含水量等因素)的影响,会加速它们的新陈代谢作用,放出更多的热量.由于粮食是热的不良导体,粮堆内的温度就会发生变化.粮堆内 I. INTRODUCTION During the storage of food, food will generate heat due to the metabolism of food and organic impurities (roots, stems and leaves of plants, etc.) and the pests and microorganisms in the food piles. Food and organic impurities and insects, molds due to Affected by storage conditions (such as ambient temperature, humidity, water content of the grain itself), their metabolism can be accelerated and more heat can be released. As food is a poor conductor of heat, the temperature inside the grain piles Change. Inside the grain pallets
