COMBINED SUPER-HIGH FREQUENCY DIRECT-HEATED DRIER Russian patent published in 2013 - IPC F26B15/26 F26B3/347 

FIELD: agriculture.

SUBSTANCE: in combined super-high frequency direct-heated drier comprising super-high frequency chambers with alternately arranged cooling chambers, the new is that the housing of the dryer has a shape of a spiral duct made along the helical line, inside the duct the intercommunicating chambers are located: the loading chamber, sequentially alternating super-high frequency chambers and cooling chambers, the discharge chamber, and on the inner side wall of each super-high frequency chamber the magnetron is mounted, the lower part of cooling chambers is connected through the air duct to the fan, and their upper parts - with an exhaust diffuser for discharging waste coolant, through all the chambers two parallel chain conveyors pass, on which the perforated trays are hingedly mounted, the drive of the chain conveyors provides cyclic-continuous movement of the perforated trays with periodic dwells, above the loading chamber the feed hopper with a feeder is mounted, and under the discharge chamber the discharge hopper with a conveyor belt is placed.

EFFECT: improving the quality of the products obtained due to removing the evaporated moisture, keeping the reasonable temperature exposure on the processed product, reducing energy consumption for drying.
