Watch>>>The TurboDryer   in action.

The continuous tray dryer handles a wide variety of feed consistencies from pasty slurries to fine powders and pellets. It has two moving parts, the shelf assembly and the fan assembly, each turning independently in a sealed housing.

Wet feed enters through a feed chute in the roof of the housing and flows onto the first shelf. The shelves are circular with cut out center and radial slots. The shelves are rigidly mounted on an inner supporting frame forming a vertical stack which rotate slowly as a unit. Material flows onto each shelf from the one above.

At the end of a revolution, the tray segment meets a stationary blade set to wipe the tray clean of material. The material flows through the radial slot onto the shelf below where the cycle is repeated and is discharged through a chute in the bottom..

Air or other drying medium is fed to the TURBO-DRYER through a side mounted vertical manifold with control dampers. Air movement inside the dryer is provided by centrifugal fans mounted on a single vertical shaft. The fan assembly rotates independently of the shelves.

The housing is totally sealed.

Advantages of this dryer include:

1. Close temperature control due to the internal mixing and recirculation of the drying medium.

2. Good product uniformity because of the positive retention time, frequent turnover of material, and contact with the drying medium.

3. Its gentle handling does not create fines resulting in a less dusty operation.

4. Compared to other air flow dryers, power requirements are low.

Many products wet with flammable solvents are dried with an inert gas virtually 100% solvent recovery.


The Wyssmont TURBO-DRYER® thermal processor has proven to be the best dryerreactor to successfully torrefy wood chips. Torrefaction of biomass is one of the most promising bioenergy technologies because it transforms a bulky biomass into a high quality product that can be readily co-fired with coal, without the need to change anything within an existing coal fired power plant.
