The drum scraper dryer is a drying equipment commonly used in chemical, food, pharmaceutical and other industries. Its working principle is to contact the material with the heating medium through the rotating drum, and use the heat transfer of the medium to evaporate the moisture in the material to achieve the drying effect.

  The drum scraper dryer is mainly composed of a drum, scraper, transmission device, heating device, exhaust device, feeding device, etc. The drum is a component of the entire equipment. It is composed of inner and outer shells. There is an interlayer between the inner shell and the outer shell. The heating medium is passed into the interlayer to heat the inner wall of the drum. The scraper is located on the inner wall of the drum and consists of a scraper bracket and a scraper. The scraper bracket drives the scraper to rotate through a transmission device to scrape the material from the inner wall of the drum, so that the material is in full contact with the inner wall of the drum.

  When working, the material enters the inside of the drum from the feeding device, and the drum drives the scraper to rotate through the transmission device, scraping the material from the inner wall of the drum to form a film, and then contacts the heating medium to gradually evaporate the moisture in the material. The exhaust device discharges the steam out of the equipment to achieve drying effect. During the whole process, the rotation speed of the drum and scraper can be adjusted according to the properties of the material and drying requirements.

  The drum scraper dryer is suitable for drying various materials, especially sticky, heat-sensitive and easily oxidized materials. Welcome to contact us if you are interested in our drum scraper dryer.
