ABSTRACT:
An apparatus for the preparationof ice cream, milkshakes, sorbet, frozen desserts and the like, from a pumpable starting mixture, comprises a storage container for the starting mixture and a cooling or freezing cylinder communicating with it via a supply conduit. A rotatably drivable stirring and scraping mechanism is disposed in the cylinder and the supply conduit discharges into an inlet chamber located on one end of the cylinder, a discharge valve being provided on the other end of the cylinder. Only the cylinder is provided with a heater for pasteurizing the starting mixture, and a thermostat is provided for limiting the wall temperature of the cylinder. Devices for transporting the starting mixture from the inlet chamber to the discharge valve are provided. To attain completely satisfactory results from the bacteriological standpoint as well as to prevent changes in flavor, the apparatus provides that a connecting conduit that can be blocked by a valve is provided between the storage container and the cylinder, discharging from the end region of the cylinder adjacent to the discharge valve.
