The present invention relates to a mixer with a mixing container and a tool shaft (8) which is arranged at least partly in the mixing container and has a drive end and a working end for a working tool (6), the tool shaft (8) being mounted on the drive end by means of two mutually set-apart tool bearings and a drive motor (7) being provided for the tool shaft (8). In order to provide a mixer which is simple and economical to manufacture and has as few movable and wearing parts as possible and the tool shaft (8) of which is, in addition, able to accommodate the considerable transverse forces occurring during operation, the invention proposes that the drive motor (7) have a motor shaft which is mounted, at least on one side, by a tool bearing.

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.

A method and a device are disclosed for converting at least one reactant into a reaction product and separating the at least one reactant. The device includes a vessel with a vessel inner volume and a confinement, submerged in the vessel inner volume, that provides a confinement inner volume in fluid connection with the vessel inner volume. First and seconds fluids, with a respective, higher first density and a lower, second density form respective lower and upper phases in the vessel inner volume. A third fluid with a third density higher than that of the second fluid forms a lower layer in the confinement inner volume, relative to an upper layer formed by the second fluid. The third fluid may be the same as or different from, and is physically separated from, the first fluid. At least one of the first, second, and third fluids is at most partly miscible with the other two, but preferably immiscible. The at least one reactant and the reaction product have different affinities for at least two of the first, second, and third fluids, and at least one of the first and third fluid contains a fourth phase which is a solid or semi solid and is capable of promoting the conversion.
