The JHD series drum yeast dryer is a single-cylinder dryer, which can be used for drying a variety of pulps, and is especially suitable for the recovery of waste yeast in breweries. The dryers of different specifications can meet the annual output of 30,000 to 100,000. Tons of brewery needs.
The drying cylinder of the yeast dryer and the material contact parts is made of high-grade cast iron, which has the characteristics of anti-corrosion and non-polluting. This machine uses conduction heating, and there is no heat loss taken away by the drying medium, so the heat utilization rate is high and the energy consumption is low, generally above 70%. This machine also has the characteristics of compact structure, small area, simple operation and maintenance, etc. This machine is designed and manufactured according to my country's national conditions on the basis of digesting and absorbing German prototypes, and has advanced performance.
The factors that affect the performance of this machine are as follows:
(1) Steam pressure (0.1-0.4Mpa) or heating medium temperature.
(2) Rotation speed (4～10r/min).
(3) Film thickness (that is, the thickness of the material attached to the surface of the dryer).
(4) Material characteristics (such as solid content, fluidity and temperature, etc.).
The main body of the yeast liquid dryer is composed of a drying cylinder, a frame, a transmission system, a scraper device, a material limiter, a scraper device, a soaking device, and a steam path system. In addition, it is equipped with an electric control cabinet and exhaust hood.
This machine is a dryer that heats materials and vaporizes moisture by indirect conduction heating. It is heated by steam. The drying cylinder (roller) is a metal hollow cylinder with a processed outer surface and extremely smooth surface. Driven by a transmission device (large and small gear transmission), the drying cylinder rotates in the axial direction and the speed can be adjusted. The slurry is preheated in the preheating tank, preheated to about 50℃, and fed into the dipping tank at the lower part of the drying cylinder by a feed pump. The drying cylinder is immersed for about 60-80mm, and the outer surface of the rotating drying cylinder is coated with a Layer uniform slurry (ie film thickness), the steam pressure in the dryer is 0.15-0.3Mpa, the slurry is heated on the outer wall of the dryer, and the moisture is vaporized and discharged by the induced draft fan. The drying cylinder rotates one week, the material is dried, and the flake material is discharged by the scraper on the outer wall of the drying cylinder, and then falls to the discharge port for collection.
