The water sprayed from the plurality of nozzles 18 provided on the dehydrating tub side portion in the dehydrating process drops off from the side of the filtering net toward the food garbage attached to the inner side of the tub by the centrifugal force when the tub is rotated, The dilution of salt and the dehydration by water spray from the nozzles are repeated so that the desalting action of the food waste is improved.

The sweeper 13 disposed on the inner side of the sieve includes an annular lower ring member 25 connected by a plurality of horizontal support members 24 in a radial direction at the central portion thereof, And an upper ring member 27 integrally formed on the upper ends of the vertical support member 26 and the vertical support member 26. [

In order to rotate the sweeper, a top portion of the upper ring member 27 is formed with a toothed portion 36, to which gears 16, 16 'arranged at at least two opposed positions are engaged, The gear 16 is driven by a motor 17 provided outside the dewatering tub to rotate the sweeper and the gear 16 'disposed on the opposite side to the gear 16 is mounted idling inside the dewatering drum, So that the sweeper is stably rotated without being inclined to one side, and the sweeper is rotatably supported at the center of the bottom surface of the sweeper.

When the sweeper is rotated, the vertical supporting member 27, which vertically connects the upper and lower ring members 25 and 27, contacts the inner side of the filtering net so that the sweeper can sweep the inner side of the filtering net when the sweeper is rotated. So that the food garbage is not discharged into the dehydrator in a state where the debris is not desalted and dehydrated.

Further, the horizontal support member 24 radially formed in the lower ring member 25 of the sweeper is rotated close to the bottom of the sieve 12 during rotation of the sweeper. The cutter 28 is fixed to the horizontal support member of the lower ring member 25 and is rotated together with the sweeper to crush the food waste in the filter net as a pretreatment before crushing the food waste in the crushing unit 60 .
