The invention discloses a freezing device comprising a heat insulating tank body, a feeding mechanism, a discharging mechanism, two conveying belts, a conveying belt stand, a top-blowing
evaporator and a horizontal type
centrifugal fan, wherein the feeding mechanism and a discharging mechanism are respectively arranged on a feed port and a
discharge port of the heat insulating tank body, and the two conveying belts, the conveying belt stand, the top-blowing
evaporator and the horizontal type
centrifugal fan are arranged in the heat insulating tank body; a supporting rod is arranged below a cross beam of a support of the top-blowing
evaporator, the supporting rod, the cross beam and the heat insulating tank body are fixedly connected to form a stressed member, and a frame-shaped fan stand is fixedly arranged on the supporting rod of the stressed member to form a stressed frame; an anti-
icing bracket is arranged below the frozen conveying belt, a
steam heating wind-shielding device is arranged below the conveying belt at the feeding port, the bottom of the feeding mechanism is provided with a conveying belt heating-up water tank, and a conveying belt tensioning shaft roll is arranged at the discharging mechanism. The invention has the advantages of stable structure, safe installation process of the evaporator and convenient use and also has the advantages of eliminating the phenomenon of
icing under the conveying belts, prolonging the continuous
running time of the freezing device and improving efficiency; and besides, because the low-temperature conveying belt is washed after immersed in the water tank and heated up, less
water consumption and good cleaning effect are achieved.
