INTRODUCTION

 The drum scraper dryer is an internal heating conduction rotating continuous drying equipment. The rotating drum adheres to a certain thickness of material film through its lower material trough. The heat is transported to the inner wall of the drum through the pipe, transmitted to the outer wall of the drum, and then transmitted to the material film so that the humidity in the material film is evaporated and dehumidified so that the content Wet materials are dried. The dried materials are shoveled away from the drum by the scraper installed on the surface of the drum and then go to the screw conveyor placed under the scraper. The dry materials are concentrated and packaged through the screw conveyor.

 The liquid or slurry material forms a film on the surface of the drum heated by water vapor or other heat carriers. The drum will be dried during one revolution. Use a scraper to scrape off the dried product, and the exposed drum surface will come into contact with the raw materials again, and form film, and then dry and be scraped off.

 The drum scraper dryer is suitable for drying liquid and viscous materials in chemical, dye, pharmaceutical, food, metallurgy, yeast and other industries, as well as drying rice flour, oatmeal, A starch, potato whole flour and other food products into flakes and powders, shape and granular.

 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.
