The stirring apparatus includes a stirring beater configured to be coaxially disposed in a mixing chamber of a freezing cylinder in a rotatable manner for pushing a mixture flowed in the mixing chamber in an inner spiral manner, and one or more scraper blades. The stirring beater includes one or more helical stirring paddles supported by a central frame and spirally extended along a length of the mixing chamber. The one or more scraper blades are mounted along the one or more helical stirring paddles respectively to define a helical diameter matching with an inner diameter of the mixing chamber of the freezing cylinder such that each of the one or more scraper blades is capable of scrapping against an inner surface of the freezing cylinder while a rotation of the stirring beater within the mixing chamber of the freezing cylinder

A mouthfeel maintaining method of an ice cream machine is provided. The ice cream machine is equipped with a freezing cylinder, a stirring device, a main refrigeration system, and a control system. When the ice cream material in the freezing cylinder is in a forming solid stage, the control system controls the ice cream machine to enter a mouthfeel maintaining state. The forming solid stage is: a stage from when all the ice cream material in the freezing cylinder is converted into all-solid ice cream until the preset hardness or the preset viscosity value is reached. The mouthfeel maintaining state is as follows that: the main refrigeration system refrigerates the ice cream material in the freezing cylinder according to the refrigeration capacity close to the lower limit refrigeration capacity. Moreover, the ice cream machine can discharge the all-solid ice cream in the freezing cylinder in the mouthfeel maintaining state.

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; a pushing portion 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 machine for making liquid/semi-liquid food products includes a container for the product; a dispenser connected to the container which allows or inhibits dispensing of the product; a mixing stirrer rotatable about an axis of rotation and mounted inside the container; a thermal system including a circuit with a heat exchanger fluid and an evaporator operatively associated with the container and including an inlet aperture for the fluid, a discharge aperture for the fluid, a first tubular element and a second tubular element coaxial with the first tubular element and having an axial direction of extension and a radial direction of extension, the second tubular element extending along an axial direction parallel to the axis of rotation and being disposed inside the first tubular element to define an annular chamber for circulating the fluid and defined by at least one microchannel, the microchannel having a hydraulic diameter of 3-13 mm.
