Abstract

A discharging nozzle for foamed material, especially whipped cream, is kept at a predetermined temperature even when a refrigeration machine which cools the device holding or producing the whipped cream is temporarily not operating. Thus, the discharge nozzle is kept substantially at the same temperature as the reservoir holding the whipped cream or as the machine producing the whipped cream. For this purpose the discharge nozzle is mounted in a solid cooled housing in heat transfer communication with a hollow jacket. The hollow jacket in turn is connected in heat communication to the device holding or producing the whipped cream. The hollow jacket is filled with a liquid which stores cold produced by refrigerating of the device holding or producing the whipped cream. The storing of the cold is accomplished by a change in the physical state of the liquid. The cold is then released to the nozzle during times when refrigeration is interrupted.

Dependent claims

An apparatus for discharging a foamed material, such as whipped cream from a device holding or producing the whipped cream, comprising housing means for said device, outlet port means extending through a wall of said housing means, refrigeration means (8') for cooling said housing means, foamed material discharge nozzle means, heat conducting tubular jacket means mounting said discharge nozzle means to said housing means for supplying foamed material through said outlet port means to the discharge nozzle means, said heat conducting tubular jacket means comprising a hollow jacket portion (12) forming a chamber holding a cooling liquid, and a solid jacket portion (14) mounting said discharge nozzle means, said hollow jacket portion being in cooling heat transfer contact with said refrigeration means, said hollow jacket portion being further in cooling heat transfer contact through said solid jacket portion with said discharge nozzle means so that the discharge nozzle means (5) is cooled by cold stored in said cooling liquid which thereby changes its physical state when said refrigeration means are temporarily inoperative.
