Zhengzhou Langke Machinery Equipment Manufacturing Co., Ltd.--the 2013 advanced unit Zhengzhou Langke multifunctional pure countercurrent grain dryer is launched

Pure counterflow grain dryers are relatively rare in terms of production and use. Most of these grain dryers are used in combination with mixed flow grain dryers, so that they can play a greater role. Generally, counter-flow, mixed-counter-flow, forward-counter-flow and forward-mixed flow grain dryers are used together. Could you please introduce the relevant knowledge? The characteristics of pure countercurrent dryer are high thermal efficiency, higher grain temperature, and the temperature and moisture content of the dried grain are relatively uniform, but the production efficiency is not very good. The counter-flow grain dryer is one of the most advanced grain drying equipment at present. The counter-flow grain dryer adopts the combined drying process of "counter-flow and counter-flow" and implements "staged variable temperature drying" according to the heating temperature of the grain. In the drying tower, there is a slow-soaking section designed between each drying section, and "drying and slow-soaking" are performed alternately. In the top drying section, a higher hot air temperature is used to quickly heat up the grain and take away part of the surface moisture. In the middle drying section, a medium hot air temperature is used to remove a large amount of moisture. After passing through the above drying section, the grain temperature has increased, so the bottom drying section Using a lower temperature can achieve the purpose of removing the moisture with strong adsorption force inside the grain grains and preventing the grain temperature from rising too high. Finally, after sufficient cooling in the cooling section, the out-of-machine grains that have reached safe moisture and temperature can be directly put into storage. store. This drying tower optimizes and combines the "downstream" and "countercurrent" drying processes to achieve the best results. It is our company's high-quality grain drying tower model.
