Rotary Dryers GEA Solid Feed Drying

Principles of Rotary Drying. The directly heated rotary dryer operates on the principle of lifting and showering the product through a hot gas stream moving either in parallel or counter-flow whereas with the indirect dryer, which is more suited to fine and dusty materials, there is little or no contact between the product and the drying gases since they are heated from the outside, via a

Rotary Dryer: Operating principle, Classifications, Uses

Indirect rotary dryer. 4. Special type. A rotary dryer is said to be of the direct type if, by virtue of its design, heat is added to or removed from the solids by direct exchange between the gas and solids. The direct heat dryers are the simplest and the most economical class. They are used when direct contact with the hot gas or air is not
