GT Roller Drum Dryer / Roller Dryer Machines (Energy Saving, Customized Design) is a kind of indirect heating / cooling dryer in continuous production. Raw material fed from top or bottom of drum and stick on the drum. Filling heating / cooling medium inside the drum, the heat / cooling then transferred to raw material, thus raw material could get dried / flaked. Flake form dried product will be scraped off, and preliminarily crushed as well as transported by screw conveyor.
The drum body of the drum dryer is heated on the inside by steam. A special composition of cast iron gives the drier a combination of favourable properties: accurate shape retention even at high steam pressure and temperature, and excellent "scraping properties" for the scraping knife.
Steam heating gives a uniform temperature distribution over the drum surface and this results in a consistent product quality. The steam condenses on the inside of the drying drum. The condensate is continuously removed from the drum, so that the largest possible surface area remains available on the inside of the drum for condensation of the steam. The steam system is a closed system, which means that the product cannot come into contact with the steam or condensate.
