During beer fermentation, a large amount of waste yeast sludge is produced, previously, breweries discharged large amounts of yeast waste directly from the production process, the single cell yeast with strong activity caused great pollution to the environment after it was discharged. Microbial yeast puree is a kind of muddy mixture with rich nutrition, which can be used as the necessary additive for making various feeds or biological fertilizers, so it has high economic value. However, due to the high moisture content of microbial yeast mud, and the requirement that the biological activity of recovered microbial yeast powder should not be less than 98%, during the drying process, the material temperature of yeast mud should not exceed 80℃, the drying time should not exceed 1 minute, and other harsh technologies, common processes and equipment are hard to guarantee.
By considering the situation of global market, our company has made unremitting efforts, eventually designing and manufacturing beer yeast dryer. The new product could fulfill continues and stable production and has the characterization of low cost, easy installation and maintain, and less need for labor. Currently, we could provide different series of drying equipment to meet the demand of different beer suppliers.
Our brewers' yeast dryer product take advantage of heat conduction between hot steam and wet materials, realizing the indirect drying process. The drum is a hollow metal cylinder whose surface is deeply processed to be clean and polished. The drum rotates to the axial under drive devices (gear drive) in an adjustable rate. Slurry is preheated to 50℃ in preheating tank and then delivered to feeding chute through pump. Drum is immersed about 60-80mm. The external surface of rotating drum is coated with a layer of uniform slurry and pumped in the hot steam under 0.15-0.3Mpa. The slurry is heated on the external surface, where moisture is taken away by draught fan. With a single circle, the wet materials can be dried completely. Knot material in the external surface is swept off by scraper and fall on outlet for collection.
With its excellent quality and reputation, Dingli beer yeast dryers win the favor of the large brewery manufacturers, establish and maintain a good cooperative relationship with the world's many breweries. More than 200 sets of BSG and beer yeast dryers running now in more than 60 countries in Europe, America, Asia, Africa and Oceania.
