A machine for producing ice cream in portions, of the type comprising a compressor (2) for refrigerant liquid inside a refrigeration coil (9), and a motor (3) driving a blade mixer (4) for forming an ice cream mixture. Specifically, the machine of the invention is provided with a device (5) for mixing a mixture of ice cream powder (17) and water flow (19) and for creaming the ice cream (23), by means of the rotation of the blade mixer (4) rotatably arranged inside the same device (5). Compared to traditional machines for the production of ice cream in portions, the invention offers the advantage of ensuring, in a simple and economical way, the best conditions for the naturalness of the final food product, without the risk of bacterial contamination from the mixing chamber.

Apparatus for treating various fluids, such as wine, must, water, oil, sauce, fruit juice, and others, to prevent contamination or the development and spread of diseases such as salmonella and legionella. The apparatus allows to avoid excessive proliferation of colonies of bacteria and yeasts which, if present in excessive quantities, can cause mould and pathogens in general. The apparatus comprises a container body containing a reticular cathode and anode that allow the liquid to pass through and are powered by an electrical connector that receives electrical current from a power supply controlled by an electronic control unit. The container body is configured to be immersed in the liquid to be treated, allowing the liquid to flow through the cathode and anode, which generate a pulsed electric field. The electrical signal has a frequency of about 300 Hz, an amplitude of 100V and pulses of few milliseconds. To increase the efficiency of the treatment, the signal changes polarity every 90 seconds.

A distribution device (5) for a liquid-vapor two-phase fluid for a heat exchanger, comprising an inlet duct (6) and a section (7) provided with a plurality of outlet ducts (7a, 7b, 7n) for the liquid-vapor two-phase fluid. The inlet duct (6) comprises a first duct section (6A) and a second duct section (6B) arranged in sequence along the flow direction (F) of the liquid-vapor two-phase fluid through the distribution device (5). The first duct section (6A) has a uniform cross-section and is provided with a plurality of turbulator elements (8a, 8b, 8c, 8d) designed to cause pre-mixing of the liquid phase and vapor phase of the two-phase fluid. The second duct section (6B) has a progressively converging and diverging Venturi-shaped cross-section designed to cause remixing of the liquid phase and vapor phase of the two-phase fluid. The device of the invention offers the advantage of both dividing the two-phase fluid into equal flows in all the supply ducts to the heat exchanger and achieving complete mixing and uniform homogenisation of the liquid phase and the vapor phase in all the supply ducts of the two-phase fluid.

A grinding machine (1) for processing a glass sheet (L) movable along a horizontal transport direction (X), comprising a control unit, at least one tool unit (3, 3A, 3B) movable along a direction (Y) transverse to said transport direction (X) of the glass sheet (L) and having a spindle (12, 12A, 12B), and a detection device (4, 4A, 4B) associated with the tool unit (3, 3A, 3B) and adapted to detect the position of the glass sheet (L) along said transport direction (X). The detection device (4, 4A, 4B) comprises a slider (5, 5A, 5B) movable along a guide direction (C) and bearing a pad (6, 6A, 6B) for contact with an edge of said glass sheet (L), an actuator (7, 7A, 7B) for moving said slider (5, 5A, 5B) along said guide direction (C), and a linear position transducer (8, 8A, 8B) for detecting the position of said slider (5, 5A, 5B) along said guide direction (C). The actuator (7, 7A, 7B) is mounted on an adjustable support (9, 9A, 9B) adapted to move said slider (5, 5A, 5B) reversibly from a first position in which said pad (6, 6A, 6B) is vertically spaced from the movement plane of said glass sheet (L), so as not to interfere with the movement of said glass sheet (L), to a second position in which said pad (6, 6A, 6B) is arranged transversely to the movement plane of said glass sheet (L), so as to be able to engage said edge of the glass sheet (L). Compared to the prior art, the invention offers the advantage of allowing to know the exact position of the glass sheet relative to the spindle of the tool unit that performs the processing of the sheet itself, thanks to a reading of the same position performed directly on the body of the glass sheet.
