摘要： An apparatus for introducing dry ice pellets into fresh meat comprises a housing, in which an injection device for introducing dry ice pellets is arranged, and guide channels, which lead to a front face of the housing, for guiding a penetration needle, and a drive device for axially moving the penetration needle. A loading unit can be inserted between a rear portion and a front portion of the housing, which loading unit is provided with feedthroughs, which can be equipped with dry ice pellets and brought into a position in alignment with the guide channels. During operation of the apparatus, penetration channels are first produced, by means of the penetration needles, in a piece of meat to be cooled, into which penetration channels the dry ice pellets are subsequently introduced from the feedthroughs using the penetration needles. The feedthrough enables efficient introduction of dry ice pellets into the meat.

摘要： For charging a refrigerant-receiving compartment of a cooling container with dry ice, a reservoir vessel has a dispensing opening and a dispensing unit which cooperates therewith and by means of which dry ice blocks stored in stacks in a magazine of the reservoir vessel are ejected one after the other from the reservoir vessel and are respectively inserted into a refrigerant-receiving compartment of a respectively provided cooling container. This makes it possible to provide cooling containers in rapid succession with a precisely metered quantity of dry ice as refrigerant.

摘要： A device for producing dry ice pellets comprises a pressing cylinder, into which an inlet opening for feeding liquid carbon dioxide leads and which is equipped with a die, which has one or more openings, and with a piston, which is longitudinally movable in the pressing cylinder. Liquid carbon dioxide is fed to the pressing cylinder, is expanded at the inlet opening, is at least partially converted into carbon dioxide snow and is pressed against and through the die by the movement of the piston. The die is in the form of a cylindrical body that can be connected to the pressing cylinder and is equipped with feed-throughs, which are oriented parallel to a longitudinal axis of the die and are dimensioned in such a way that the length and the diameters of the feed-throughs correspond to the length and the diameters of the dry ice pellets to be produced.
