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.

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 dual-axis mixer for food products includes a product holder that is configured to hold a sealed product cup containing a food product to be mixed. The mixer has a primary axis of rotation about a central axis, and a secondary axis of rotation radially offset from the central axis. In doing so, the secondary axis positioned to rotate around the primary axis. Furthermore, the product holder is located at the secondary axis and is configured to rotate about the secondary axis. Rotation about the primary axis applies centripetal force to the food product, and the secondary axis rotates the product holder to churn the food product within the product cup.

A machine for processing and preserving liquid or semi-liquid food products, includes: a frame having an upper surface; a container for the product with an internal stirrer, the upper surface having an opening to the container; an actuator rotates the stirrer relative to the container or vice-versa; a refrigeration system, including: a closed circuit to circulate a heat transfer fluid, an evaporator, associated with the container, a compressor, a condenser, and a lamination member; a cover movable between a closed position for access to the container via the opening, and an open position, allowing access to the container, the cover defining in the closed position a volume between an internal surface of the cover and the upper surface; an air suction system within the volume including a suction unit and a suction mouth in fluid communication with the volume; a control unit controls the actuator and the suction unit.

The present disclosure belongs to the technical field of refrigeration equipment, and in particular to a slush machine, comprising a material tank of which two sides are provided with a support bracket, respectively; an agitator component including a body upper shell, wherein one side of the body upper shell is provided with an agitator of which one end extends into an interior of the material tank and a driving mechanism for driving the agitator.
