Abstract: A machine for the treatment of food mixtures with an improved performance includes a container or cylinder for collecting a food mixture, integral with a frame structure and equipped with an upper lid, for closing the container and hinged to the frame, so as to be in a closed or open position on an upper opening of the container, in the container there being a rotating shaft, which is coaxial to the container and which supports in rotation scraping and mixing blades at the bottom and sides of the inner and bottom walls of the container, a blender being positioned in an opening of the lid. Particularly, the blender can be positioned so to be freely removable.

Abstract: A device for the quick heating of fluid material, in particular food, comprises: a container (20) for the fluid material and a heater (12). According to the invention said heater consists of a microwave generator (12), or magnetron, equipped at one end with an antenna (13). Said container (20) comprises a treatment body (21) equipped with at least one recess (24) for the passage of said fluid material to be treated and with a seat (23) for receiving said antenna (13), said recessed treatment body (21) being enclosed in an airtight outer structure (28, 29).

Abstract: A method for feeding a liquid mixture (11) to the beating cylinder (12, 30) of a soft ice-cream production machine, is characterised in that only a single measure of liquid mixture, withdrawn from a feed vessel (10), is firstly subjected to rapid heating to a temperature of around +85.degree. C., then immediately afterwards to rapid pre-cooling, and is finally fed to a beating chamber (20) of said beating cylinder (12, 30) in which said mixture is beaten. This ensures that the measure is free from bacterial load.

Abstract: The control system comprises at least one common hardware section (1) for all anticipated applications, consisting essentially of a control keyboard card (2), a display card (3) and a logic card (5), including a microprocessor (6), a non-volatile memory (7), at least one thermometer probe (4), and a control relay unit (10) for the different working parts of the machine under control, and software for the said microprocessor (6), varying as a function of the intended application of the hardware section (1).

Abstract: A pasteurizer for foodstuff mixtures comprises a tank with which are associated heating, cooling and mixture circulation means. The tank (11) is ellipsoidal in shape with a bodyshell (12) and a base (13), and the said mixture circulation means comprise an auger-type device (15) mounted adjacent to the base (13), which is in the form of a disc (16) and is slightly drawn so as to have a tapered circumferential edge (17). From the upper side of the disc (16) there extend tabs (18) which form respective mixture aspiration ports (19), while below the ports (19) there extend respective centrifugal blades (20), which move the aspirated mixture through the ports (19).

Abstract: Heating apparatus of tank type comprises a first and a second heating element in a flexible material applied respectively onto the peripheral and bottom wall. The first and the second element have respectively a substantially rectangular and circle-sector shape.

Abstract: A blade mixer device for liquid and/or doughy products contained in a cylindrical tank comprises a structure that supports at least a first and a second pair of blades acting, respectively, on the base and on the wall of the said tank; the bearing structure can moreover be associated in a removable manner with an operating shaft which extends coaxially with the tank. Characteristically, the said structure consists of a portal element restrained in a removable manner astride the top of the said operating shaft, to rotate together with it.

Abstract: A tank-type heating apparatus of the kind employing heating elements realized in flexible material, applied to the outer walls of the tank of the said apparatus, wherein the outer surface of the said heating elements that is opposite the surface in contact with at least part of the outer surface of the said tank is in contact with a mantle of heat-conductive material which extends over the whole of said outer surface of the said heating elements and which also extends beyond the said surface so as to enter into contact also with at least part of the outer surface of the said tank not covered by the said heating elements.

Abstract: An evaporator for coolant fluids comprises two tabular elements of different diameter that are inserted coaxially one into the other so as to form a circumferential space within which coolant fluid can circulate. The said space is subdivided into a plurality of adjacent annular chambers by means of a series of annular baffles force-fitted in a sealing manner between the said two tubular elements. The said annular chambers intercommunicate by means of at least a bore made in each of the said baffles, the bore of one baffle being made diametrically opposite the bore in the adjacent baffle. At the opposed ends of the evaporator provision is also made for an inlet duct and for an outlet duct for the coolant fluid.

Abstract: A homogenizer device for the production of whipped cream comprises an external sleeve (10) and an internal sleeve (11) between which is formed a labyrinth (13) in which the air-emulsified whipped cream is fed under pressure through an upstream conduit (25) and then delivered in a homogenized condition in a downstream position through a dispensing spout (22). The internal sleeve (11) features an axial bore (16) within which slides a stem (14) which is provided at its upstream extremity with an actuating piston (15) which also controls an aperture (24) providing communication between the delivery conduit (25) and the labyrinth (13). At its downstream extremity, the stem (14) acts on a separate valve (18) which is under tension from a spring (19) and which controls the outlet of the axial bore (16) communicating between the labyrinth (13) and the dispensing spout (22).

Abstract: A dual-purpose machine for making icecream and crushed-ice syrup drinks essentially comprising a cylindrical whipping chamber within which rotates a mixer to one shaft of which are operationally connected motor means, characterized in that said motor means consist of a first and a second motor means which can be selectively operated to control the rotation of said mixer at a relatively high speed for the making of icecream and at a very low speed, of the order of a few RPM, for the making of crushed-ice syrup drinks.

Abstract: A homogenizer device, in particular for the production of whipped cream, comprising in combination, the following components: an external sleeve and an internal sleeve between which is formed a convoluted labyrinth, the internal sleeve housing a valve element which forms with it a chamber communicating with said labyrinth and with the delivery tube for the base mixture, said valve element consisting of a stem bearing a valve at one of its ends and a valve at its opposite end, the former being a valve for controlling the dispensing of the whipped cream and the latter being a valve for controlling the conduction of the mixture through said labyrinth, said valve element being also translatable against a counteracting spring.
