Turbo-Dryer has only two moving parts: tray/shelf assembly and fan assembly, both rotating independently in a fixed sealed housing.
Wet feed enters the Turbo-Dryer through a feed chute in the roof of the housing and flows onto the first shelf. Shelves are circular with cut-out center and radial slots and are rigidly mounted on an inner supporting frame, forming a vertical stack, which rotates slowly as a unit. Material flows onto each shelf from the one above, forming a pile. The rotation of the tray/shelf assembly carries the pile past a stationary blade set to level the pile to fill the tray at a uniform height. At the end of a revolution, the tray segment meets a second stationary blade set to wipe the tray clean of material. Material is held stationary by the wiper blade, while the tray continues its rotation. It flows through the radial slot onto the shelf below where the cycle is repeated and then progresses downward from shelf to shelf through the dryer and is discharged through a chute in the housing bottom.
Air or other drying medium is fed to the Turbo-Dryer through a side-mounted vertical manifold with control dampers. Air moves inside the dryer by centrifugal fans mounted on a single vertical shaft. Fan assembly fits into the shelf assembly, rotating independently of the shelves. Drying medium leaves the dryer through a roof exhaust.
Turbo-Dryer housing, totally sealed, encloses and supports both tray/shelf and fan assemblies; supports stationary parts of the dryer, wipers and levelers; and consists of a metal frame and insulated side panels, roof, and bottom.
