Abstract: Apparatus for producing so-called soft ice cream comprising a refrigerated feeding tank (12) for a liquid mixture (11) suitable for the preparation of soft ice cream, a group for pasteurising the mixture and a whipping cylinder (50). According to the invention, said group for pasteurising the mixture comprises a heating device (20) for an amount of mixture equal to at least one portion of product, a pre-cooling device (30, 30?) for said amount of heated mixture and a storage tank (40, 40?) for storing the pasteurised mixture at a constant temperature.

Abstract: A batch mixer having a barrel which forms a cylindrical sealed chamber having a section consisting of two mutually communicated circles, and two rotors housed in the chamber to mix a mixing material by rotation, at least one of the inner wall of the barrel and the surface of the rotor having a plurality of recessed parts or protruding parts. The recessed parts or protruding parts are formed of grooves or projections extended in the direction crossing to the rotating direction of the rotor rotated in the chamber to mix the material. According to this structure, a batch mixer excellent in the controllability of material temperature during mixing can be provided.

Abstract: This invention provides a ram for use in a mixer with counter-rotating non-intermeshing rotors on which the central portion of the ram utilizes a apex, either a point or a line produced by a “V” or similar shape, that protrudes a given distance into the mixing chamber and on which the end portions of the ram are either horizontal such that they do not protrude into the mixing chamber at all or are otherwise shaped such that they protrude into the mixing chamber less than the apex of the central portion of the ram.

Abstract: A dough treatment facility comprises, among other things, a dough kneading arrangement, which comprises an inner kneading drum, an outer kneading drum which is moved in relation thereto within the scope of a kneading motion, and a plurality of kneading compartments which are at least partially defined by the kneading drums. The kneading motion is actuated by means of a kneading drive. This drive comprises a first drive component for rotation of the inner kneading drum, a second drive component for rotation of the outer kneading drum, and a third drive component for periodic motion of the outer kneading drum relative to the inner kneading drum, this motion having a motional component parallel to the longitudinal axis of the kneading drums. A kneading drive gear actuates the driving motions of the three drive components, derived from the motion of a single transmission shaft.

Abstract: A dough treatment facility comprises a dough feeder, a dough metering arrangement, a dough kneading arrangement, a transfer arrangement disposed between the dough metering arrangement and the dough kneading arrangement as well as a dough discharge arrangement. A delivery piston, which is driven by a drive mechanism, forms part of the dough metering arrangement. A drive component of the drive mechanism comprises a load sensing device, which is disposed for sensing the load by which the delivery piston, when pressing the dough, acts on the dough.
