  "abstract": "In a freezing plant, a handling device comprises vertically extending guides fixed to a base and supporting a double-deck carriage, the lower deck of the carriage comprising a frame, and the upper deck comprising a platform which is adapted to receive carriers containing a product after the loading thereof, horizontally extending guides carrying bars serving for feeding the carrier with the product to the carriage platform, further translation thereof into a space between cooling plates and returning the empty carrier back for the loading, as well as at least one stop located under the carriage and serving for expelling the product from the carrier, the carrier being delivered, after the freezing of the product, to the carriage frame during its lowering down.",
  "claims": [
    "1. A freezing plant having cooling plates and a handling device for placing carriers containing a product into a space between said cooling plates and delivers them from this space after the freezing, said handling device comprising: a base, vertically extending guides fixed to said base; a double-deck carriage having a lower deck and an upper deck, said carriage being movably mounted on said guides, the lower deck of the carriage comprising a frame, and the upper deck comprising a platform for receiving the carrier containing the product, horizontally extending guides, bars reciprocatably and rotably mounted on said horizontally extending guides for feeding the carrier containing the product to said platform of the carriage, further translation thereof into the space between said cooling plates and returning the empty carrier back for the loading, and at least one stop located under said carriage serving for expelling the product out of the carrier to said frame of the carriage during the lowering down thereof.",
    "2. A plant according to claim 1, wherein there is provided a mechanism for precompacting the product located under the carriage, said mechanism comprising a plate and spring-loaded levers connected thereto by means of draw-bars.",
    "3. A plant according to claim 1, wherein the bars have slits at their free end and are mounted on the horizontally extending guides so as to be rotatable in the vertical plane in which the reciprocation of the bars in the horizontal direction is performed by common devices operatively connected to the bars by means of a lever."

  "description_excerpt": "The present invention relates to freezing plants which are widely used in the foodstuff industry.\n\nKnown in the art is a rotary-type freezing plant for continuous freezing of food products in a space between the cooling plates of the rotor having a handling device.\n\nThe handling device comprises two independent assemblies.\n\nThe loading assembly is arranged outside the insulated circuit of the plant and comprises a platform accomodating a carrier which is made in the form of a frame to be filled with a product, the platform performing reciprocations for introducing the carrier with the product into the space between the cooling plates of the rotor. The unloading assembly is arranged inside the insulated circuit and comprises a cam system for moving the cooling plates apart, a mechanism for stripping the frozen product from the plate in case of the adhering thereof to the plate, and a mechanism for delivering the carrier with the frozen product outside of the insulated circuit (cf. U.S.S.R. Inventor's Certificate No. 269,940, Int. Cl. F 25 d).\n\nThe product to be frozen is manually placed into the carrier mounted on the platform. Then the platform supporting the carrier enters the space between the cooling plates of the rotor and, returning into the initial position, abandons the carrier with the product in the rotor. The product is frozen during the rotation of the rotor. Upon completion of the freezing, the cooling plates supporting the carrier with the product are stopped at the unloading station.",
