  • Patent number: 6817203
    Abstract: The invention relates to a device for the discontinuous production of ice-cream from a liquid mixture. Said device comprises a processing container, in which at least one tool is mounted so that it can rotate and repeatedly apply the liquid mixture to and scrape the latter from the refrigerated interior wall of the processing container, a fill opening for the liquid mixture and a discharge opening for dispensing the ice-cream from the processing container. The longitudinal axis (L-L) of the processing container (10) is inclined at a first acute angle (&agr;) in relation to the horizontal (H) and the rotating tool (20) comprises spatulas which are configured and mounted in such a way that they continuously transport the ice-cream mass which forms to the discharge opening (15), lying at the lowest point of the processing container (10).
