Abstract: A device (1) for detecting the bacterial charge in a liquid or semi-liquid food product comprises a main containment body (2), an analysis chamber (3), located inside the containment body (2) and designed to contain a certain quantity of product to be examined, one or more heating means (4) designed to heat the product inside the analysis chamber (3), at least one temperature sensor (5) designed to monitor the temperature of the product inside the analysis chamber (3) and sensor means (6) designed to detect the impedance in the product inside the analysis chamber (3). The analysis chamber (3) has an elongate shape and extends along a principal axis (3a), while the one or more heating means (4) are symmetrical about a plane at right angles to the principal axis (3a).

Abstract: Method for the production of sealing elements on plastics articles. Said method includes the step of producing a film of silicone rubber on the sealing surface of the article. Advantageously, this film is formed by co-moulding or co-extrusion with the plastics article itself. The thickness of the said film may vary from a few tenths of a millimeter to a few millimeters. In the case of cylindrical elements, such as the pistons of the delivery cocks of ice cream machines, this film preferably covers only the side wall or the sealing part of the side wall of the cylindrical element, while in the case of flat elements, this film covers only the sealing surface of this element.

Abstract: Method for controlling and optimising the cycle for production of ice cream depending on the mixtures used in the ice-cream making machine, comprising a freezing cylinder exchanging heat with the evaporator of a refrigerating circuit, and a stirrer/scraper element rotating inside said freezing cylinder and actuated by a suitable electric motor, and further comprising a processing element, sensors for detecting continuously the temperature values of the refrigerating gas at the inlet and at the outlet of the evaporator and means for detecting continuously the value of the electric power used by the motor, said temperature values and said values for the electric power used by the motor being continuously input into said processing element; a software program in said processor for processing said values being able to provide an output signal which drives an impulse solenoid valve which introduces continuously the hot gases removed from the exhaust of the compressor into the main stream of refrigerating fluid.

Abstract: Device for supporting and handling containers of liquid ice cream mix in ice cream making machines of the type in which the liquid ice cream mix is contained in special disposable containers which, after having been connected to a feeder tube equipped with a perforating spike, are turned upside down and placed in a refrigerated chamber in the body of the machine. Said device comprises a basket of an essentially cage-like structure open at the front and provided at the bottom and top with supporting surfaces, the said cage-like structure pivoting in the center of its flanks on the flanks of the chamber of the said machine.

Abstract: Pasteurizer for food products comprising a tank provided with agitator means connected to actuating means, characterized in that said tank has on the bottom a chamber cavity in which said agitator means are accommodated, said chamber being provided on the bottom with a hole which faces, towards the inside of the chamber, the internal cavity of a cylindrical sleeve projecting inside the chamber and fixed thereto, and, towards the outside, the actuating means, said agitator means being provided with a movement transmission shaft which, inserted in the cavity of the sleeve and through the hole on the bottom of the chamber, is coupled to the actuating means, said internal cavity of the sleeve being provided with fluid sealing means.

Abstract: A combined machine for the dual production of crushed ice or ice cream includes a processing cylinder provided with a stirrer means, a refrigerating circuit and a device for operating the stirrer. The refrigerating circuit includes an evaporator in heat exchange relation with the processing cylinder, a compressor, a condenser, a filter and a control system for controlling the expansion of the refrigerating fluid. The control system includes a thermostatic expansion valve and a capillary tube, inserted in parallel in the circuit, as well as a switch disposed in the flow circuits of the control system.

Abstract: A stirrer for machines for making ice cream includes a section of a rotary drive shaft, a first hub supporting a plurality of angularly equidistant radial spokes integral with the drive shaft section and a second hub supporting the same number of spokes as the first hub. The spokes of the second hub are provided at their ends with fastening components. The first hub contains radial passages that extend from a position diametrically opposite the spokes and through a longitudinal axis of the spokes to accommodate screw-type fastening members. The stirrer further includes a plurality of stirrer blades which have, at their axial ends, tapped holes for engaging the fastening members and fastening components to operatively connect the first and second hubs.
