The Design Of Flights In Cascading Rotary Dryers Drying

The Design Of Flights In Cascading Rotary Dryers Drying

14 The rate of drying in rotary drying mainly depends on nature of motion of solids and gassolid contact In rotary dryer heat transfer rate enhanced by introducing flights in drum placed parallel along the length of the drum The flights lift the solids and suspend them across the section of the dryer from different position of drum

2007427it is reasoned that the ehd flights which have an equal distribution of particles across the horizontal diameter of the rotary drum dryer give the optimum distribution in the context of the heat and mass transfer operations of the rotary drying processn industrial design which approximates the optimum flight design is suggested.

31 rotary dryers as the dryer rotates solids are picked up by the flights lifted for a certain distance around the drum and showered through the air in a cascading curtain most of the drying occurs at this time as the solids are in close contact with the gas flight action is also partly responsible for.

Abstract the effectiveness of the rotary drum drying process depends primarily on the contact between the cascading particles and the drying gases within the drum this paper considers first the factors which contribute to the cascade pattern and which influence the design of the lifting flights which distribute the particles in the top half of the drum.

An 18 dryer drum is not the only option rotary dryer drums as small as 4 diameter can evaporate anywhere from 200 500lbshr rotary drums much smaller than this have efficiency losses so an alternate drying system may be more beneficial using the same example above with a product at 50 mcwb a small rotary drum dryer can take.

The Design Of Flights In Cascading Rotary Dryers

In designing cascading rotary dryers it is important to size the flights correctly in order to ensure that they can adequately accommodate the contents of the drum a set of equations has been derived to calculate the solids holdup on angular and extendedcircular flights in such dryers.
