The invention provides a device (1) for processing and treating chocolate, with a container (2) and stirring means (3) arranged therein, wherein the container (2) has a processing interior (2a) with a cylindrical wall (4) and an outwardly curved bottom (5) and is set up obliquely, i.e., the center axis (ZA) of the cylindrical wall (4) is inclined with respect to the vertical, and wherein the stirring means (3) comprises at least one stirring arm (7), which is rotatable about this center axis (ZA), while projecting from the center axis (ZA) of the cylindrical container (4) at least also in the radial direction, and a conching tool (6), which is rotatably arranged at or near the bottom (5) or the lowest vertical point of the container (2) about a an axis of rotation (DA), and wherein the conching tool (6) rotates faster than the stirring arm (7) during operation. In a method according to the invention for processing and treating chocolate, it is provided that a starting mass or an intermediate product of chocolate is filled in an inclined cylindrical container (2) and rotating therein along with at least one stirring arm (7), which rotates about this center axis (ZA), while projecting from the center axis (ZA) of the cylindrical container (2) at least also in the radial direction, as well as processed simultaneously by means of a rotatable conching tool (6), which rotates faster than the at least one stirring arm (7) about an axis of rotation (DA), which is inclined relative to the center axis (ZA) of the cylindrical container (2). Furthermore, the invention provides for the use of a universal machine for processing and treating nutritional and food products, processing and treating chocolate, wherein the universal machine comprises a container (2) and stirring means (3) arranged therein, and wherein the container (2) has a processing interior (2a) with a cylindrical wall (4) and an outwardly curved bottom (5), and arranged obliquely, i.e. the center axis (ZA) of the cylindrical wall (4) is inclined with respect to the vertical, and wherein the stirring means (3) comprise at least one stirring arm (7), which is rotatable about the center axis (ZA) of the cylindrical wall (4), while projecting from the center axis (ZA) of the cylindrical container (2) at least also in the radial direction, and wherein it is further provided that the stirring means (3) comprise a conching tool (6) rotatably arranged at or

A cup is provided for a device for preparing a frozen food product from a liquid mixture with a stirring element of the device stirring the liquid mixture in the cup while the cup is being cooled by a cooling unit of the device. The device includes a cup holder with a cavity for receiving the cup. The cup holder includes a first upper surface surrounding an entrance opening of the cavity, and is provided on the first upper surface with at least one upwards first protrusion. The cup has a predetermined height such that the cup extends a predetermined distance above the first upper surface. The cup includes at its top a circumferential flange provided with at least one first extension, which is arranged such that it contacts the at least one first protrusion for preventing rotation of the cup in the cavity.

Systems and methods have demonstrated the capability of rapidly cooling the contents of pods containing the ingredients for food and drinks.

A screw feeder includes: a case that includes a material putting-in portion through which a fluff material is put in and a material putting-out portion through which the fluff material is put out below the material putting-in portion; and a screw that includes a rotational shaft and a blade portion, the rotational shaft being provided rotatably inside the case, the blade portion being spirally mounted on the rotational shaft; wherein the screw is rotated with repeated alternation of a slope-down direction in which the blade portion slopes downward spirally in a vertical direction and a slope-up direction in which the blade portion slopes upward spirally in the vertical direction.

An apparatus for mixing bone cement for use in orthopedic surgeries includes a mixing region and an agitator for mix the cement ingredients. A temperature sensing means of apparatus determines when that the cement mix can no longer be used. The apparatus can be operated or acted on by a power tool for the mixing of the bone cement. The power tool and/or mixing apparatus may include a mechanical torque limiter that inhibits the agitator as a result of mixing torque exceeding a threshold value. A timer of the apparatus may be started by a sensor of the apparatus or by the user in response to a mechanical torque value. When the timer is complete, a cue by the apparatus signals to the user that the mixed cement is ready and able to be applied.

Provided is a highly efficient pipe-type flocculation mixer, comprising: a feeding pipe, a mixing pipe, a discharging pipe and a mixer. The feeding pipe, the mixing pipe and the discharging pipe are disposed in parallel and sequentially communicated. The mixing pipe is a circular pipe and has two blind ends. The mixer comprises a driving motor, a mixing blade and a central shaft. One end of the central shaft is coupled to the driving motor, and another end of the central shaft is coupled to the mixing blade. The size of the mixing blade enables the mixing pipe to exactly accommodate the mixing blade. Also provided is a feeding-mixing device, wherein an agent can be introduced into a hollow central shaft via an agent feeding chamber, and be sprayed out from the central shaft into a mixing chamber; said agent feeding manner enables sufficient mixing.
