Spent yeast is a by-product of the brewery. Fresh waste yeast is not easy to preserve and needs to be dried by a steam dryer to be processed into high-quality feed.

Working principle of spent yeast dryer

Drum scraper beer yeast dryer is a single-drum drying equipment that uses steam heating. The steam consumption has a great relationship) put it into the preheating tank, preheat to about 50°C, use the feeding pump to input the immersion tank at the lower part of the drying cylinder, immerse the drying cylinder about 60-80mm, and the outer surface of the rotating drying cylinder will be stained Apply a uniform layer of slurry, and the steam pressure is 0.15-0.3Mpa into the drying cylinder. The dry material (if it is yeast milk, the water content is less than 9%) is scraped off by the scraper, and then falls to the discharge port for collection. The dryness of the material is controlled by adjusting the steam pressure and the rotating speed of the drum. The condensed water in the drying cylinder is sucked out by the siphon, and the secondary steam is recycled through the coil at the bottom of the preheating tank.
