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. According to research It is found that beer yeast contains a lot of nutrients, protein, etc. and is a high-quality feed. However, if you want to rationally utilize beer yeast, you need to use our yeast dryer.

Yeast dryer is a piece of equipment made according to the characteristics and status of yeast. It is different from the original drum dryer. This equipment adopts a single-cylinder structure and uses indirect heat conduction for drying. The drying cylinder only needs to rotate once. It is an indispensable equipment for processing yeast materials to complete the drying of materials. So some friends may be curious, what is the principle of yeast dryer drying yeast? Let’s find out together.

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

During the drying process: first, the slurry is preheated in the preheating tank to about 50°C, and then the feed pump is input into the immersion tank at the bottom of the drying cylinder. The drying cylinder is immersed about 60-80mm, and the rotating dryer The outer surface of the cylinder is coated with a uniform layer of slurry. The steam pressure introduced into the drying cylinder is 0.15-0.3Mpa. The slurry is heated on the outer wall of the drying cylinder, and the moisture is vaporized and discharged by the axial flow fan. The drying cylinder rotates once and the material is dried. The flaked material is discharged 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. The dried yeast nutrients are preserved, have good drying properties, are suitable for long-term storage, have good palatability for livestock such as cattle and sheep, and the economic value has been further improved.

The main advantages of the equipment are that the equipment dryer has a large drying capacity and is suitable for large wineries and breweries to dry yeast materials. The heat source used by the equipment is relatively clean and has less pollution to yeast. The equipment uses high-temperature drying. Drying, it has a good killing effect on impurities in yeast during the drying process, and can effectively control the damage of microorganisms to cattle and sheep in the subsequent feed use process.
