The moisture content of the yeast waste liquid in the brewery reaches about 90%, the solid content is relatively low, and the material is in the form of mud. So what is the technical principle of the yeast waste liquid dryer compared with the conventional dryer? Yeast dryer is a drying cylinder scraper structure, the equipment is composed of drying cylinder, frame, transmission system, dipping device, material limiting, scraping device, dipping device, steam exhaust hood and other devices.
The specific principle is as follows: the waste yeast liquid enters the storage silo through the feeding port of the drying system, and the height of the material liquid is 40-60mm higher than the bottom surface of the cylindrical dryer. The overflow port overflows to ensure the height of the material liquid level. Open the intake valve to let the steam enter into the cylindrical drying cylinder, so that the surface temperature of the drying cylinder rises rapidly. When the surface temperature rises to 80-90 degrees, start the transmission device and adjust the rotation speed of the drying cylinder according to the condition of the material to make the cylindrical drying cylinder The drying cylinder rotates at a constant speed. During the rotation of the drying cylinder, the material in the storage silo will adhere, and the material will rotate together with the drying cylinder. When turning to the limiter, the thickness of the adhered material layer will be uniform through the material limiter shaft to ensure that the final drying state of the material is uniform. The drying cylinder continues to rotate. During the rotation, the moisture in the material on the surface of the drying cylinder is gradually evaporated. When it rotates to the position of the scraper device, it is scraped up by the scraper and falls into the dispersing conveying system.
