Abstract
A device for the manufacture of a frozen aerated product which includes a freezer, a pump for introducing a frozen aerated product mix and air into the freezer, a tubular crystallizer system having upstream and downstream ends and having a longitudinal shaft within and extending beyond the ends of the crystallizer system through seals, a ram for reciprocating the longitudinal shaft upstream and downstream, the longitudinal shaft being provided with one or more scrapers in a transverse plane along its length which divide the crystallizer system into compartments, whose perimeters are adjacent to and capable of scraping the internal wall of the crystallizer system and whose bodies are provided with at least one longitudinal channel, a high pressure stuffing pump for feeding the frozen aerated product from the freezer to the crystallizer system, a jacket containing a heat transfer fluid for removing heat from the frozen aerated product within the crystallizer system, and a backpressure valve for conveying the frozen aerated product out of the crystallizer system.
