Brewer's yeast is fresh yeast produced in the beer production process. Fresh yeast is a good feed for pigs, but because it will deteriorate within a few hours, it can only be discharged with sewage, which seriously pollutes the environment. In order to overcome the above shortcomings, make full use of Fresh yeast, turning waste into treasure, has successfully developed "brewer's yeast drying equipment. After drying, it can be made into high-quality protein feed brewer's yeast dry powder, which can be used as feed additive. It not only protects the environment but also improves the economic value.

The working principle of yeast dryer:

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 transmission), the drying cylinder rotates around the axial direction and the speed can be adjusted. The slurry is preheated in the preheating tank, preheated to about 50°C, and fed into the dipping tank at the lower part of the drying cylinder with the feeding pump, the drying cylinder is immersed for about 60-80mm, and the outer surface of the rotating drying cylinder is coated with the upper layer Uniform slurry (that is, 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 water is vaporized and discharged by the axial flow fan. When the drying cylinder rotates for one week, the material is dried, and the flake material is discharged by the scraper on the outer wall of the drying cylinder, and then falls to the discharge port for collection.
