Beer yeast is more widely used as a feed additive and is widely used in the breeding industry. Feed yeast contains a variety of nutritional elements, which can promote the growth of livestock and poultry and enhance the ability to resist diseases. It is a pollution-free green trace element additive; the use of yeast dryers to recover and develop yeast has objective economic, environmental and social benefits benefit.
The working principle of the yeast dryer: The yeast dryer is a dryer that heats materials and vaporizes water by indirect conduction heating, and uses steam to heat. The drying cylinder (roller) is a metal hollow cylinder with a processed outer surface and extremely smooth surface. Driven by a transmission device (large and small gear transmission), the drying cylinder rotates in the axial direction and the speed can be adjusted. The slurry is preheated in the preheating tank, preheated to about 50℃, and fed into the dipping tank at the lower part of the drying cylinder by a feed pump. The drying cylinder is immersed for about 60-80mm, and the outer surface of the rotating drying cylinder is coated with a The uniform layer of slurry (ie film thickness), the steam pressure in the dryer is 0.15-0.3Mpa, the slurry is heated on the outer wall of the dryer, and the moisture is vaporized and discharged by the axial fan. The drying cylinder rotates one week, the materials are dried, and the flake materials are discharged by the scraper on the outer wall of the drying cylinder, and fall to the discharge port for collection.
