The invention relates to a rotary shaft for processing foodstuffs, the rotary shaft has a rotation axis and the rotary shaft comprises at least one tool which extends along the rotation axis. The tool has an airfoil profile such that the tool comprises a leading edge, a trailing edge, an upper surface and a lower surface. Further, the tool comprises at least one fluid channel between the mean camber line of the airfoil profile and the upper surface of the tool.

A mixing chamber for mixing a variety of dry ingredients with a liquid is disclosed. The mixing chamber has an accumulation chamber that evenly distributes ingredients as they pass a liquid spray nozzle, resulting in uniform hydration. The liquid may be sprayed at a variety of pressures to achieve varying levels of granule hydration to permit the manufacture of dough, batter, or other compositions. Even dry ingredients which are generally slow to absorb moisture may be rapidly and evenly hydrated without an excess of liquid. Process parameters, such as volume flow rate of the dry ingredients, can also be varied.

A household mixer appliance having an open top mixing container, a hook and a drive arrangement. The mixing container has a side wall portion with a through hole for the drive arrangement and the hook is arranged to be rotatable around an axis of rotation within the mixing container via the drive arrangement. A seal is arranged between the drive arrangement and the side wall portion of the mixing container, and the drive arrangement includes a quick-release mechanism to which the hook is attachable.

A hydrator includes a dry module with a vertically oriented tube having a central axis, an interior, an upper inlet aperture, a lower outlet, and an inlet section including a dry inlet. A mixing segment includes a vertically oriented tube having an interior wall, a mixing-segment inlet at an upper end, and a mixing-segment outlet at a lower end. The mixing segment is vertically aligned with and sealingly connected to the outlet of the dry module. A rotating hydrator shaft has a liquid channel and a longitudinal axis aligned with the central axis of the dry module. Dry blades are disposed on and rotate with the hydrator shaft in the mixing segment. A hydrator nozzle is disposed on and rotates with the hydrator shaft and has a plurality of outlets in fluid communication with the liquid channel and open to the mixing segment for discharging liquid from the liquid channel.

A device for the processing of liquids and/or solids comprises a disposable layer adapted to shield a working surface from coming into contact with, and being fouled by, the processed liquids and/or solids, and apparatus suitable to apply a negative pressure in a gap between said disposable layer and said working surface, thereby causing said disposable layer to adhere to said working surface.

A mixing machine includes a head extending over a bowl receiving location, the head including a downwardly extending rotatable output shaft for receiving a mixer tool. A drive train including a motor having an output operatively connected to drive a planetary gear system that effects rotation of the rotatable output shaft about its axis and orbiting of the shaft axis about another axis. A control system includes a master control unit and a slave control unit, the master control unit connected with a first sensor located along the drive train between the motor and the planetary gear system, the slave control unit connected with a second sensor, wherein both the slave control unit and the second sensor rotate with a part of the planetary gear system, wherein the master control unit and the slave control unit are configured for wireless communication with each other.

A dough mixer includes a main unit with a motor arranged therein and a dough mixing assembly mounted thereon. The dough mixing assembly includes a dough mixing bowl, a top cover, a transmission shaft connected to the motor and is arranged in the dough mixing bowl, a dough mixing unit connected to the transmission shaft and including an upper end, and a scraper unit detachably connected to the upper end of the dough mixing unit. The scraper unit includes a first bowl wall scraper including a first blade fitted to an inner wall of the dough mixing bowl, a second bowl wall scraper including a second blade fitted to the inner wall of the dough mixing bowl, wherein the second bowl wall scraper is arranged opposite to the first bowl wall scraper, and a central scraper including a third blade matched with an outer wall of the transmission shaft.

A mixing machine includes a head extending over a bowl receiving location, the head including a downwardly extending rotatable output shaft for receiving a mixer tool, the head including a planetary system therewithin for effecting rotation of the rotatable output shaft about its axis and orbiting of the shaft axis about another axis. A motor includes an output operatively connected to drive the planetary system. A control system includes a plurality of sensors, each sensor located for detecting a respective condition of mixing machine, and a diagnostic control operable to (i) track outputs from the plurality of sensors over time, (ii) analyze the tracked outputs and (iii) produce an alert indication based upon the diagnostic control identifying a performance characteristic indicative of a need for service or repair of the mixing machine.

An agitator assembly for use with industrial mixers that includes at least two rotating agitators, wherein each rotating agitator includes an agitator shaft, wherein the agitator shaft defines an axis of rotation extending from a first end of the agitator shaft to a second end of the agitator shaft; and first, second, and third sweep blades mounted on the agitator shaft, wherein the pitch angle of each sweep blade relative to the axis of rotation of the agitator shaft is between 30-60; and wherein the rotating agitators rotate in opposite directions relative to one another when the assembly is in use.
