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 near the bottom (5) of the container (2), in particular at or near the lowest point of the container (2) with respect to the vertical, and rotating faster than the stirring arm (7) during operation.
