A kit for connecting to a processing container a device for feeding a liquid or semi-liquid food product, including at least: an internally hollow pipe having a first end and a second end, wherein at least one between the first and the second end includes an enlarged, external terminal portion; a receiving element provided with a hole for receiving at least the enlarged, external terminal portion at one end of the pipe and with an abutment for stopping the end of the pipe inside the hole; means for pushing and locking the enlarged, external terminal portion at the end inside the receiving hole in order to allow locking the enlarged, external terminal portion against the abutment.

A method of making a heat exchanger includes providing an inner tube extending longitudinally along a central axis and having an inner surface bounding a product chamber and an outer surface. An outer tube is formed and positioned about the inner tube. The outer tube is disposed coaxially about and circumscribing the inner tube in a radially spaced relationship. Forming the outer tube and positioning the outer tube about the inner tube occur simultaneously.

A machine for making liquid or semi-liquid food products includes a processing chamber for processing a basic mixture and including a stirrer and thermal treatment system operating in conjunction to convert the basic mixture into a liquid or semi-liquid product; an electronic drive and control unit; a dispensing device having a dispensing nozzle connected to the processing chamber to deliver the product; a support having a seat for housing a receiving container; a movement device for vertically moving the support between a vertical position away from the nozzle and a vertical position close to the nozzle; and a device for rotating the housing seat about a vertical axis. The electronic drive and control unit is operatively connected to the movement device and to the device for rotating the housing seat to drive them according to a predetermined law of motion.

A machine for making liquid or semi-liquid products, including a first container adapted to contain a basic mixture, having an inside surface and an outside surface and equipped with a stirrer disposed inside the first container; a thermodynamic system comprising a circuit for circulating a heat exchanger fluid and a first heat exchanger associated, in use, with walls of the first container, the first heat exchanger is defined by at least one element which is fixable, in use, to the outside surface of the first container, having an open cavity, extending uninterruptedly and defining, when coupled with the outside surface, a channel for circulating heat exchanger fluid, the element also having at least one inlet and one outlet for the heat exchanger fluid.

A connector for connecting a deformable bag for liquid or semi-liquid products to a machine for distributing the product and includes a body with an opening passing therethrough and acting as a product outlet and connected to the machine, with a thermal sensor supported so as to be positioned inside the bag, in contact with the liquid or semi-liquid product. The sensor is fixed in a second opening that is parallel or almost parallel to the product transit opening and a connecting cable comes out of the end of the body intended to remain outside the bag. The assembly formed by the bag and the connector and the machine for distributing a liquid or semi-liquid food product supplied with the bag equipped with the connector.

A frozen beverage dispensing machine includes a barrel. A liquid side of an expansion tank is connected to the barrel. A gas side of the expansion tank is separated from the liquid side by a bladder. A controller is configured to receive liquid pressure measurements from a liquid pressure transducer and is configured to initiate a fill process to provide a flow of liquid through the liquid side of the expansion tank into the barrel in response to the liquid pressure measurements falling below a liquid cut in pressure value. The controller is configured to initiate a gas pressure adjustment process when the liquid pressure measurements are less than a target gas side pressure.

An apparatus for making a frozen dessert. The apparatus including a reservoir located within a chassis for receiving a liquid dessert mixture and a rotatable paddle located within the reservoir. The paddle can have a body coupled to at least one respective scraper element by a living hinge, such that the scraper element has a scraping edge that is radially-outward biased by the living hinge for abuttingly engaging a wall of the reservoir. The reservoir and the axis of rotation can be substantially horizontally directed, with a substantially vertically-orientated lid closing an opening of the reservoir, the lid defining an aperture for receiving the mixture or enabling egress of the frozen dessert.
