Grain Dryer details grain dryer airflow direction according to the Food and relative motion can be divided into horizontal flow, Francis, downstream, upstream and along the countercurrent mixing countercurrent, along Francis and other types. First, my company now produces ZQHGT series along countercurrent mixing countercurrent cis Francis (octagonal, square) grain dryer, dry in the digestion and absorption of foreign technology, based on the use of grain drying mathematical modeling computer design and advanced technology derived Best drying models technical parameters are set downstream, upstream, Francis dryer respective advantages, to achieve high temperature rapid drying, increase drying capacity, without increasing the heat consumption to ensure uniform moisture content and grain quality . Mainly suitable for grain, farm, seed and feed, ethanol and other enterprises, high-moisture grain drying. It has a variety of grains and oilseeds (corn, rice, wheat, soybeans, rapeseed, etc.) produce continuous drying operation. It consists of unloading food, lifting, cleaning, transportation, bake the former warehouse, dryers, drying after the warehouse, heat, electrical and control units can be installed outdoor use, can also be installed in the plant. Second, characteristics: 1, good drying grain quality and low cost. In countercurrent along grain dryers, drying medium first contact with cool, damp grain, and flows in the same direction, which not only makes full use of high-temperature hot air, and so that each grain drying process can get the same temperature, the valley grain itself maximum heating temperature is lower than 55 ℃, after each drying section, using a tempering process, so that before entering the next drying cereals, grain moisture content and temperature of the center to the surface, tends to be more balanced in favor of the next a stage of drying, and ensure the quality of baked bread. 2, precipitation amplitude, thanks to the multi-stage drying process a precipitation rate can be as high as 15-18%. 3, saving significant, proven drying compared to other models, energy savings of 20-25%. 4, adapt to a wide range of convenient combination, according to different grain precipitation, set different precipitation and drying section meet production requirements. 5, the high degree of automation with stepless adjustment row of grain, with the monitoring system, automatic adjustment of hot air, easy and reliable operation.
