现在美国、日本、苏联等发达的农业国家的粮食生产从种、管、收、干燥、清理、贮藏到计量等生产环节都实现了一条龙的机械化生产过程。粮食干燥一般分为人工干燥和自然干燥。人工干燥是指用一种热源产生热气流(热风)通过烘干机,与机内粮食接触进行热交换而降水的一种工艺方法。它按通风温度不同又可分高温和低温干燥。高温干燥指风温达80～160℃左右。垦区内目前使用的
Nowadays, the grain production in advanced agricultural countries such as the United States, Japan and the Soviet Union has realized a one-stop mechanized production process from production, management, collection, drying, cleaning and storage to measurement and other production links. Dry food is generally divided into artificial dry and natural dry. Artificial drying refers to a heat source to generate hot air (hot air) through the dryer, and food contact with the machine for heat exchange and precipitation of a process. It is different by ventilation temperature can be divided into high temperature and low temperature drying. High temperature drying refers to the wind temperature of 80 ~ 160 ℃ or so.
