GRAIN DRIER Russian patent published in 2002 - IPC

FIELD: agricultural engineering. SUBSTANCE: grain drier has cylindrical-conical housing 11, working chamber with netted walls 3, transverse partition wall 4 which may be mounted in upper as well as in lower part of working chamber, perforated tube 5 for supplying first gas flow, perforated tube 6 for supplying second gas flow, pipe union 8 for exit of waste heat-carrier, sectioned feeder 9, pipe union 10 for feeding wet material, cyclone 11, pipe union 13 for supplying first gas flow, pipe union 12 for supplying second gas flow. Feeding and receiving parts of grain drier are equipped with charging and discharge coaxial cones 27 arranged at distance of (25-30)x10 ^-3 m, with cones being installed at an angle of generatrix of 45-50 deg. Netted walls 3 of working chamber are deflected from vertical plane by angle of 6-8 deg. Perforated tube 5 for supplying first gas flow is adapted for supplying ozonized heat-carrier. Transverse partition wall 4 may be positioned in upper as well as in lower part of working chamber. Drier of such construction may be used for drying grain, combined feed, as well as for dehumidifying other bulk products and granulated materials. Improved quality of materials subjected to drying procedure is provided by properly regulated mode of transportation of materials in drier working chamber. EFFECT: simplified construction and increased efficiency in grain drying by ozonizing heat-carrier. 2 cl, 5 dwg
