发明名称 Freezer segment for a freezer for confectionary with segments including channels for direct evaporation of CO<sub>2 </sub>
摘要 The present invention concerns a freezer segment for a freezer of the type used for casting confectionery in molds which are cooled for freezing and subsequently supplied with heat for a short period, whereafter stripping occurs. Cooling of the molds is effected by using direct evaporation of CO2. The advantage of such a freezer segment is that there is no use for both a primary and a secondary cooling circuit. Another advantage in using a system according to the invention is that working with temperatures down to about minus 50° C. is enabled, compared to about minus 40° C. with brine systems. The low freezing temperature entails that the capacity of a given system is increased by about 40%.

主权项 1. A freezer segment for a freezer of the type to be used in making confectionery, including edible ice of ice-cream and so-called water ice or combinations thereof, where confectionery is cast in moulds which are cooled for freezing after filling and to which heat is applied after sufficient freezing or which is subjected to shock cooling for a short period so that removal from the mould may take place, wherein the freezer segment comprises at least one row of a plurality of individual moulds, and plate-shaped, extruded multi-chamber profiles with multiple individual channels containing CO2 for transport of the CO2 in one direction from one end of the extruded multi-chamber profiles to an opposite end of the extruded multi-chamber profiles and direct evaporation of the CO2 and, wherein the multiple individual channels of at least one of the plate-shaped extruded multi-chamber profiles extend along the plurality of individual moulds for cooling of the plurality of individual moulds in the at least one row of individual moulds by heat conduction between the plurality of individual moulds in the at least one row of individual moulds and the CO2 in the multiple individual channels, wherein the at least one row of the plurality of individual moulds forms a mould cassette that is arranged along at least one wall, wherein the wall is partially or entirely constituted by the extruded multi-chamber profile, and wherein a gap appears between the mould cassette and the extruded multi-chamber profiles.
