3.1 Rotary Dryers Rotary dryers potentially represent the oldest continuous and undoubtedly the most common high volume dryer used in industry, and it has evolved more adaptations of the technology than any other dryer classification. All rotary dryers have the feed materials passing through a rotating cylinder termed a drum. It is

 — Cone or drum . Role of cone or drum is taking the solid feed in it .and dry the material. Cyclone Separator . During the drying there in RCVD, vapour which are separated from solid material will carry some amount of fine powder with him .If loser is very fine or light in weight then definitely some amount of powder will come with vapour.

 — In rotary cylinder type grain dryers, the diameter must be between 0,3 and 3m, depending on the volume of product to be processed. Rotary Cylinder Length. For the calculation of the total length of the rotary dryer, it should only be taken into account that the diameter is 10 to 25% of its length. Retention Time

variables of drying on the drying-time curve should be determined in order that an optimal design can be developed. 2.
