The dryer is indirect heating type composed of the casing with jacket and shaft with disc which contain steam or other heating media. Hollow inclined discs are adopted for obtaining high heat transfer coefficient and raising oscillation effect. As the discs rotate, the dryer has self-cleaning effect to scrape adhered material on shafts, discs and casing off automatically. In this way, the drying performance is enhanced by the prevention of adhesion of material and the renewal of the heat transfer area.
Sticky material such as sewage-sludge, Starch, Aluminum hydroxide, Magnesium hydroxide, ABS-resin, Polycarbonate, Polyacetal.
