Working principle of roller scraper dryer
In drum dryer rotates on its longitudinal axis which is heated hallow metal drum , this metal drum is used to dipped in the solution to be dried .
As the dipping process completed the solution on the drum forms as a film on the surface of the dryer and made to dry, to form a layer on the surface of the metal drum. While the drum is rotating the suitable knife which is present just down to the metal drum scraps or peel offs the dried materials from the drum.
The drying of the paste-like material is to adjust the thickness of the material and to compact the material layer. On the side close to the feeding device, a material compression shaft is installed to make the material evenly spread on the drum. In order to make the material easier to fall off when the scraper discharges the material, before the scraping, the cold air pipe can also be used to blow a certain amount of cold air to cool the material.
