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. It was found that brewer's yeast contains a lot of nutrients, protein and so on, which is a kind of high-quality feed. After being processed by a yeast dryer, it can be used as a feed additive.

Yeast dryer is a kind of equipment made according to the characteristics and state of yeast. It is different from the original tumble dryer. This equipment adopts a single-cylinder structure and adopts indirect heat conduction for drying. The drying cylinder can be rotated for one week. Completing the drying of materials is an essential equipment for processing yeast materials.

Brewer's yeast dryer is a drying equipment that heats materials and vaporizes and dries moisture by indirect conduction heating. It uses steam as a heating heat source. Scraping device, feeding device, air system, accessories and equipment mainly include electric control cabinet, exhaust hood, pulverizer, automatic baler, etc. The machine is conductive heating, no drying medium takes away heat loss, high heat utilization rate, low energy consumption, compact structure, small footprint, simple operation and maintenance, anti-corrosion, no pollution and other technical characteristics.
