Abstract
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%.
