An oven comprises a cooking cavity, a stirring member extending, in use, into foodstuff contained in a vessel disposed in the cooking cavity as well as drive means to provide, in use, relative movement between the stirring member and the vessel. The drive means comprises means to rotate, in use, the vessel with respect to the stirring member about a rotating axis. The oven comprises a swivel means comprising a motor to swivel, in use, the stirring member by means of the motor about a swivel axis extending at an angle of between 60-120 degrees, preferably substantially perpendicular to the rotating axis.

An oven comprises a cooking cavity, a stirring member extending, in use, into foodstuff contained in a vessel disposed in the cooking cavity as well as drive means to provide, in use, relative movement between the stirring member and the vessel. The oven comprises a displacement device to move the stirring member from outside the cooking cavity through an opening in a wall bounding the cooking cavity into the cooking cavity as well as, in use, into the vessel disposed in the cooking cavity.

A mixing device includes a container for receiving mixing material, with an emptying opening being arranged in the bottom thereof, and a closure cover for closing the emptying opening. The mixing device includes an emptying opening that can be easily and space-savingly opened and closed. The closure cover includes two closure cover portions which can be reciprocated relative to each other between a closed position in which the two closure cover portions are in contact with each other and together form the closure cover and an opened position in which the two closure cover portions are spaced from each other so that an opening is formed between the two closure cover portions for removal of the mixing material from the container.

A mixing device includes a mixing container for receiving mixing material and a mixer cover, wherein a first seal and a second seal is provided between the mixing container and the mixer cover. The first seal and the second seal are so arranged that a first air space is formed between the first seal and the second seal.

A paddle in a three-pronged fork-like shape with the middle part longer than the others cannot uniformly knead a highly viscous fluid.

A paddle includes an arm portion disposed outside a container and a paddle portion integrally formed on the distal end of the arm portion and disposed inside the container. The paddle portion includes a horizontal part, vertical parts protruding upward from both end portions of the horizontal part, and a coupling shaft portion protruding upward from the middle of the horizontal part to the arm portion. Providing an inwardly protruding portion on the upper end of the second vertical part makes it possible to mix a mixing object in an area corresponding to a non-fluid area by using the inwardly protruding portion.

A conversion device for converting linear movement in a stationary system into rotary movement about a pivot axis in a system which rotates about an axis of rotation that is not identical or parallel to the pivot axis. The conversion device has a lift element and a lift device with which the lift element can be moved with translatory movement relative to the stationary system. The lift element has first and second lift element portions connected together by a rotary bearing so that the first lift element portion can be rotated relative to the second lift element portion about the axis of the rotary bearing. The first lift element portion is connected to the lift device and the second lift element portion is connected to the conversion device. The conversion device is connected to a shaft positioned on the pivot axis so that a linear movement of the second lift element portion is converted into a rotary movement of the shaft about the pivot axis.

Mixing device having a container rotatable about container axis, with emptying opening being arranged in the bottom thereof, rotatable mixing tool arranged in the interior of the container, and closure element for closing the emptying opening. The closure element can be pivoted about a pivot axis for opening and closing the emptying opening. With the emptying opening closed, the closure element has inner surface arranged within the container, outer surface arranged outside the container, and edge surface arranged opposite an edge surface of the emptying opening. The closure element, emptying opening and pivot axis are of such a configuration and arrangement that a point arranged furthest away from the pivot axis on the inner surface or the edge surface describes a circle in the pivotal movement, wherein the closure element is arranged within the circle and the edge surfaces of the emptying opening are arranged outside the circle.

A compression device, means for controlling the compression device, a drum having an inner chamber, means for rotating the drum, and first and second delivery devices for delivering first and second materials into the inner chamber of the drum while the drum is rotating. The compression device compresses the first and second material in the inner chamber of the drum while the drum is rotating about the center of the drum in response to the means for controlling the compression device. The apparatus may include a stirring device; and a means for controlling the stirring device; wherein the stirring device is configured with respect to the drum so that the stirring device can be moved up and down to a desired depth within the drum and rotates within the inner chamber of the drum to stir the first and second materials in the drum while the drum is rotating.

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.

A mixer is disclosed including a sealed mixing chamber having an interior, and a rotating mixing bowl within the interior of the sealed mixing chamber. A stand operatively supports the sealed mixing chamber. The stand includes: a foundation, a mixing chamber base movably coupled to the foundation and positioning the sealed mixing chamber at an angle relative to horizontal, and a linear actuator system configured to move the mixing chamber base relative to the foundation in at least one linear direction. A rotating mixing head is operatively positioned and sealingly disposed within the sealed mixing chamber, the rotating mixing head rotating within the rotating mixing bowl. The mixer and a related method provide for ceramic suspension mixing with reduced cooling and possibly without cooling the suspension.
