The freezer enclosure is maintained at a temperature equal to or less than the freezing point of the beverage. Gears, rotatably mounted on a shelf, include sets of aligned interconnected gears and gears connecting the gears in the sets. A drive gear is mounted to and moveable with the shaft of a motor. The drive gear is connected to one of the gears in one of the sets to drive the gears in each set. A coaster-shaped member is moveable with the gears and supports a bottle which contains the beverage. The bottle is locked to the member such that it rotates with the member. The motor continuously rotates the bottle to agitate the beverage to keep the beverage from freezing. Internal baffles in the bottle increase the agitation resulting from the rotation.

A machine for making liquid or semi-liquid food products includes a plurality of supply containers containing a basic mixture and deformable wall, so the space occupied by each first container depends on a quantity of basic mixture therein. A processing container includes a stirrer and thermal treatment system, operating with one another to convert the basic mixture into a liquid or semi-liquid product. A connecting system connects the supply containers to the processing container to transfer the basic mixture from one of the supply containers to the processing container and includes a plurality of pneumatically operated closing valves, where each of the valves is associated with one of the supply containers and can be activated and deactivated independently of the remaining valves to allow the placement of one of the containers in connection with the processing container.

A machine for making liquid or semi-liquid food products includes a frame and a thermal system, which performs at least one thermodynamic cycle using a main heat exchanger fluid, and a production unit. The production unit is provided with a processing container having a cavity which defines a processing chamber for making a liquid or semi-liquid food product, a stirrer, applied or applicable on the frame at a fixed position and fitted or fittable in the processing container, and coupling means between the processing container and the drive shaft to allow coupling and hence transmission of motion from the motor to the processing container. In particular, the stirrer is provided with an inner core and an outer covering made of different materials.

A machine for making liquid or semi-liquid products includes a thermal system using a main heat exchanger fluid, a compressor, a first heat exchanger and a pressure reducing element, all affected by circulation of the main heat exchanger fluid. A motor includes a drive shaft rotatable about a vertical axis. A production unit includes a first container with a processing chamber for making ice cream and a stirrer insertable into the first processing container. A second container includes a cavity rotatably housing the first container and which is fixed relative to a frame. Channels for circulating the main heat exchanger fluid are associated with the second container and define for the thermal system a second heat exchanger in which the main heat exchanger fluid circulates. A coupling mechanism couples the first container and drive shaft for transmission of motion from the motor to the first container.

The invention relates to apparatus and method of making a frozen confectionary product such as ice cream or sorbet in which a confectionary mix is churned in a vessel whilst a liquid gas such as liquid nitrogen is added. Existing churning apparatus moves a stirrer through the ice cream mix in an epicyclical motion. This tends to splash liquid nitrogen so that it evaporates without contributing to the freezing of the ice cream. In the improved mixing method, the stirrer is repeatedly drawn against the inside wall(s) of the vessel. This reduces splashing of the liquid nitrogen. The drawing action also removes build up of frozen confectionary product on both the stirrer and the vessel walls and allows unfrozen confectionary mix to move to the edges of the vessel and be preferentially frozen.

A machine for making liquid and semi-liquid products includes a first container and first mixer for processing a basic product and a second container and second mixer for converting the basic product into a desired product. First and second heat exchangers are operatively associated respectively with the first and second containers. First and second drive units respectively drive the first and second mixers. A connecting duct allows transfer of the basic product from the first container to the second container. A separating element is associated with the duct and switchable between a separating configuration in which the transfer of basic product from the first container to the second container through the duct is prevented, and a connecting configuration in which a transfer of basic product from the first container to the second container through the duct is allowed.
