Yeast is an important substance in the beer brewing process. After the beer production is completed, a large amount of yeast cannot be used and is discarded or landfilled, which seriously wastes resources, pollutes the environment, and brings huge challenges to the rational treatment of waste. Studies have found that beer yeast contains a large amount of nutrients, protein, etc. It is a high-quality feed, but in order to rationally utilize beer yeast, a beer yeast dryer is needed.

  Yeast dryer is a kind of equipment made according to the characteristics and state of yeast. Different from the traditional drum dryer, this equipment adopts a single cylinder structure and uses indirect heat conduction for drying. The drying cylinder can complete the drying of the material after one rotation. It is an indispensable equipment for processing yeast materials.

  The yeast dryer is composed of ① drying cylinder, ② frame, ③ transmission system, ④ dipping device, ⑤ material limiter, ⑥ scraping device, ⑦ dipping device, ⑧ steam exhaust hood of steam system, etc.

  During the drying process: first, the slurry is preheated in the preheating tank to about 50℃, and then the feed pump is input into the dipping tank at the bottom of the drying cylinder. The drying cylinder is immersed in about 60-80mm, and the outer surface of the rotating drying cylinder is coated with a uniform layer of slurry. 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. After the drying cylinder rotates for one circle, the material is dried, and the flake material is unloaded by the scraper on the outer wall of the drying cylinder and falls to the discharge port for collection. At this point, the drying of the yeast dryer is completed, and the nutrients of the dried yeast are preserved, with good dryness, suitable for long-term storage, good palatability for livestock such as cattle and sheep, and further improved economic value.

  The beer yeast dryer is suitable for drying a variety of slurries, energy-saving and small footprint. If you are interested in yeast dryer, please contact us.
