The blade membrane dryer performance characteristics

The scraper film dryer is a round, jacketed, straight container with a high-speed rotating shaft in the middle , segmented on the shaft , and flexible blade scrapers on the segmented shaft. Using the film principle, it can be operated continuously under vacuum conditions or in inert gas mist, in which the rotating flexible scraper distributes the wet material in the form of a film on the heated contact surface, and the cylinder on the contact surface has a heating medium interlayer. The film layer of the material immediately gets heat from the heating surface, and the moisture evaporates and diffuses and concentrates. The dry material film layer is scraped off by the rotating scraper. The clean cylinder heating surface is scraped on the wet material again, and the cycle repeats until the material reaches the point. Until the required end point moisture content.
