An apparatus for the preparation of ice cream, milkshakes, sorbets, frozen desserts and the like, in each case from a pumpable starting mixture, comprises a storage container (1) for the starting mixture and a cooling or freezing cylinder (2) arranged below said container with which it communicates
An apparatus for the preparation of ice cream, milkshakes, sorbets, frozen desserts and the like, in each case from a pumpable starting mixture, comprises a storage container (1) for the starting mixture and a cooling or freezing cylinder (2) arranged below said container with which it communicates via a supply conduit (25), in which cylinder (2) a stirring and scraping mechanism (9) is arranged, the supply conduit (25) opening into an inlet chamber (7) located at one end of the cylinder (2), a discharge valve (19) being provided at the other end of the cylinder (2), only the cylinder (2) being provided with a heating (6) for pasteurizing the starting mixture, a thermostat (53) being provided to limit the wall temperature of the cylinder (2), and devices being provided for transporting the starting mixture from the inlet chamber (7) to the discharge valve (19). To obtain a bacteriologically safe pasteurization product on the one hand and to eliminate any alterations to the flavor on the other hand, a closable connecting conduit (22), which opens out of the end region (21) of the cylinder (2) adjacent the discharge valve (19), is provided between the storage container (1) and the cylinder (2). A freezing device (62) connected with the cooling aggregate (58) of the apparatus is arranged on the connecting conduit (22) to block it.
