CONTINUOUS LOOSE MATERIAL DRYING DEVICE Russian patent published in 2012 - IPC F26B9/06 F26B11/04 

FIELD: machine building.

SUBSTANCE: in continuous loose material drying device, trays of drying cabinet are made in the form of screw drums which have convex shape and concave shape, which are installed in turn one under the other. Screw drums of convex shape are made along the perimetre of three and more strips rolled in vertical plane and in-series connected to each other, having variable width of convex curved shape, rolled in vertical plane in longitudinal direction, bent along screw lines in transverse direction and bent along cuts, with chamfered walls in transverse and longitudinal direction, located in pairs at an angle to each other on both sides of strips so that there formed along the perimetre of drum are broken screw lines facing each other and broken screw surfaces with equal variable pitch throughout the drum length, and screw drums of concave shape are made of strips of variable width of concave shape, rolled in vertical plane in longitudinal direction, bent along screw lines in transverse direction and bent as to cuts, with chamfered walls in transverse-longitudinal direction, which are located at an angle to each other on both sides of strips so that broken screw lines and broken screw surfaces with variable pitch are formed along the perimetre of screw drum of concave shape and face each other.

EFFECT: improving the device design.
