一、谷物干燥技术的现代化过程国外谷物干燥技术的现代化过程大体上分三个阶段:机械化阶段、自动化阶段、高质量低成本阶段。本世纪以来,随着世界各国农业机械化的进程,谷物干燥也随之先后机械化。这个阶段的时间较长,从简易的烧固体燃料的热风谷物干燥机的应用,到初步完善的有一定程度自动控制的谷物干燥机的出现(1949年),约经历近半个世纪的时间,大体以五十年代末为界。以英美为例,在此期间内的主要谷物干燥机的情况是:
First, the modernization of grain drying technology Foreign grain drying technology in the process of modernization generally divided into three phases: the mechanization phase, the automation phase, high-quality low-cost stage. Since the beginning of this century, with the progress of agricultural mechanization in various countries in the world, the drying of cereals has also been followed by mechanization. This phase takes longer, ranging from the simple application of hot air grain dryers for burning solid fuels to the initial perfection of a somewhat automated grain dryer (1949), about half a century old, Basically in the late fifties for the community. In the case of Anglo-American, the main grain dryer during this period is:
