Beer yeast dryer is a professional drying equipment for waste yeast. According to the needs of different customers, there are double cylinder yeast dryer and single cylinder yeast dryer. Today I will share with you the technical process of double cylinder yeast dryer.
The working principle of beer yeast dryer drying: The yeast dryer is a dryer that heats materials and vaporizes water by indirect conduction heating, and uses steam to heat. The drying cylinder (drum) is a metal hollow cylinder with a processed outer surface and a very high surface finish. Driven by a transmission device (large and small gear drive), the drying cylinder rotates around the axis and the speed can be adjusted. The slurry is preheated in a preheating tank, and preheated to about 50 ° C. It is fed into the lower immersion tank of the dryer with a feed pump. The dryer is immersed in about 60-80mm. The outer surface of the rotating dryer is coated with a coating. The layer of uniform slurry (ie film thickness), the steam pressure in the drying cylinder is 0.15-0.3Mpa, the slurry is heated on the outer wall of the drying cylinder, and the water is discharged by the axial flow fan after vaporization. The drying cylinder rotates once, and the materials are dried. The scraped materials are discharged by the scraper on the outer wall of the drying cylinder, and then collected at the discharge port.
At present, Zhengzhou Dingli yeast dryer can be used for drying a variety of slurries, especially suitable for the recovery of waste yeast in breweries. Different specifications of dryers can meet the needs of 50,000 to 300,000 tons of breweries per year. If you want to know more about yeast dryer, please feel free to contact us.
