Drying Lectures and Solved Problems
The allowable mass velocity of the gas in a direct dryer depends on the dusting characteristics of the solid being dried and ranges from 2,000 to 25,000 kg/m 2 ·h for coarse particles; inlet gas temperatures are typically 120 – 175°C for steam heated air and 550 - 800°C for flue gas from a furnace. Dryer diameters range from 1 – 3 m; the ...

DRYERS
78451. A dryer (or drier) is a machine or apparatus used to remove moisture. It may be a small laboratory oven taking a few grams of moist material or a large industrial unit handling tonnes of wet feed per hour. An industrial dryer is never a stand-alone unit; it is part of a drying system which includes the feeder, the heaters and product ...

Dryer Design: Choosing the Right Drying Technology for Your
Rotary Dryers are Direct Dryers designed with rotating, "tumbling" drums and internal lifters to "rain" the moist solid through the passing heated drying air. The challenge of this dryer is maximizing the time the wet feed is exposed to the heated drying air. The better the contact, the shorter the rotary dryer's length and cost.
