	FLUIDIZED BED DRYER

Click to enlarge image

Mechstar Fluidized bed dryer is the ideal process equipment for Granule drying, Tempering and cooling of extremely problematic products, i.e.granule, crystalline, powdery and fibrous substance

Mechstar Fluidized bed dryer is the only excellent dryer unit with a fluid dynamically produced more ideal fluidzed bed, which means significantly improved energy efficiency and increased product quality.
The final dry product discharges by overflow and underflow way automatically through outlet chute, and it can produce high efficiency product due to optimum heating and cooling capabilities.

Ultra High Efficiency Granule Dryer

Mechstar Fluidized bed dryer is the ideal process equipment for Granule drying, Tempering and cooling of extremely problematic products, i.e.granule, crystalline, powdery and fibrous substance

DRYING / COOLING

These are the most frequent applications of fluid beds.
Different process systems are applied depending upon product, volatiles, operational safety and environmental requirements.
Featuring atmospheric air in a once through system where water is to be removed. Normally a push-pull system is used to balance the fluid bed. Depending upon the product and available heat source, direct or indirect heating may be applied. The exhaust air is cleaned by e.g. bag filter, cyclone with or without wet scrubber.
Incases where products pase a dust explosion risk, open cycle systems feature pressure shock resistant components or alternatively semiclosed cycle, selfinertizing layouts can be considered.

fluid bed by spraying a liquid into the fluidized layer particles.
Particulate solids ideal for fluid bed processing may be formed in an independent process step such as granulation crystallization, coagulation, or polymerization, followed by machanical dewatering. Particles and Granules may also be formed by spray drying and granulator
In other cases dry or wet solid particles may have to undergo a degree of agglomeration or granulation prior to entering the fluid bed.

Rewet agglomeration and granulation system
In the rewet agglomeration, granulation system, a fine power is conveyed to an agglomeration chamber where the power is dispersed in air and contacted with a spray of liquid. Most, porous agglomerates are formed and subsequently dried under lenient fluidization conaitions in a Vibro-Fluidizer. After colling, the power is discharged, classified, and fines recycled for further agglomeration together with fines from the exhaust air dust collector. Rewet agglomeration systems are typically used for food products like coffee, cocoa-sugar, where instant properties and coarse particles are required.
