the design of the drum dryer, the product is applied continuously as a thin film at the bottom or top of the main drum. As the drum rotates and is heated on the inside, the product dries on the outside of the drum surface. The brief exposure to a high temperature reduces the risk of damage to the product. The water

Rotary dryers are comprised of a rotating drum, into which the material is fed, in combination with the drying air. Flights, or lifters, pick up the material from the bed, carrying it over, and dropping it through the air stream to …

Rotary dryers are comprised of a rotating drum, into which the material is fed, in combination with the drying air. Flights, or lifters, pick up the material from the bed, carrying it over, and dropping it through the air stream to maximize heat transfer between the material and drying air.

Rotary drum dryers operating in co-current mode are commonly used for drying food and feed in leaf form, reducing the damage caused by the high air temperatures typical of these dryers, as well as ...

A double-drum dryer (Fig. 3.4) is made of two cylinders with equal lengths and diameters, rotating horizontally in opposite directions (Tang, 2003, p. 211).The space between the two drums can be controlled based on the film thickness. This type of drum dryer is mostly used for fewer viscous products, in which the liquid product is fed into …

Most often, rotary dryers are of the direct-ired type, meaning that the drying air is in direct contact with the material. Some dryers, however, are of the indirect type, whereby the dryer is heated externally, to avoid direct contact between the material and the drying air. Rotary dryers are comprised of a rotating drum, into which the ...
