Get PriceRotary dryers work by tumbling material in a rotating drum in the presence of a drying air. They can also be indirectly heated to avoid direct contact between the material and processing medium. The drum is positioned at a slight horizontal slope to allow gravity to assist in moving material through the drum.
Get PriceThe dryers may either facilitate continuous or batch processing with the modes of gas-solid contact including: fixed/moving beds (conveyors), fluidized beds, and rotary dryers (tumbling dryers/kilns). • Conductive dryers: Conduction-based drying can use high temperature jacketing, externally wall firing, or the use of heated cartridges/inserts.
Get PriceThe thin sheet containing heat-sensitive materials, such as vitamins, can also be dried at a lower tem-. perature in a vacuum. The irreversible thermochemical transformations. during the slurry’s first contact with the hot drum can. also be used to simultaneously impart certain re-. quired quality of the dried product.6 Starch slurries.
Get PriceDrum dryers are devices which are rational in most to perform evaporation and drying at the same time. Because the drum dryer is a heat-transfer drying system, its thermal efficiency is better than that of the other type of dryers and it is very economical. Because no liquid is left inside at shutdown, processing is possible to the last one drop.
