A rotary drive device for a mixing or grinding cooking appliance includes (i) a rotary subassembly, (ii) a rotary drive member of a food processing arm and, (iii) a rotary coupling member of the rotary subassembly with the drive member for transmitting a rotational movement from the rotary subassembly the drive member. The coupling member is movable between a first position in which the coupling member is adapted to transmit motion in a single direction of rotation of the rotary subassembly and a second position in which the coupling member is adapted to transmit motion in two directions of rotation of the rotary subassembly.

An emulsification module for a food processor enables the careful and methodical introduction of ingredients (e.g., oil) into the main container, thus allowing the same to emulsify the ingredients. The emulsification module includes a container configured to be removably connected to, and rotate with, the rotating blade assembly, and one or more oil dispensers positioned on a side surface thereof. The centrifugal forces generated by the rotation of the blade assembly causes the oil in the container to be propelled up the inside walls of the same and come out of the oil dispensers and drizzle down the side walls of the main container. Whisk members positioned on the bottom of the module (between the blades of the blade assembly) assist in mixing of the drizzled oil with the ingredients to achieve the desired emulsification.

Disclosed herein is an apparatus for facilitating grinding of grindable material. The apparatus including a container, a lid, a blade assembly, a secondary blade, and a rotating assembly. Further, the container receives the grindable material in a container interior space through a container opening of the container. Further, the lid removably attaches to a container side wall of the container for openably closing the container opening. Further, the blade assembly rotatably positioned within the container interior space. Further, the secondary blade is attached to and extends laterally from the container side wall in the container interior space. Further, the secondary blade is vertically spaced from blades of the blade assembly by a secondary vertical distance. Further, a rotating mechanism of the rotating assembly couples with the blade assembly for rotating the blade assembly based on a pull force received by a pull cord of the rotating assembly.

An appliance (100) for processing foodstuffs with a drive (2) including a pull-cord roller (21) having a concentric recess (22), in which there is arranged a spring element (23) located on the inside, the spring element (23) being operatively connected to the pull-cord roller. Through the drive (2), the working unit (4), which can be made to rotate, is driven, the working unit (4) being arranged in such a way that the external toothing (62) of the drive wheel (61) engages in the internal toothing (63) of the working unit (4) and, when the drive (2) is actuated, the working unit (4) is made to rotate. A locking element (10), which is equipped to lock the drive (2) in a non-operational state, and an unlocking element (11), which is equipped to actuate the locking element (10) in order to release the locking, contribute to the high operational safety of the appliance.

Methods and apparatuses for mixing food are disclosed. In an embodiment, a mixing device includes a housing including a cavity configured to hold an item and at least one cord attached to the housing. The at least one cord is configured to cause the housing to rotate when the at least one cord is pulled in a direction away from the housing. In another embodiment, a method of mixing includes placing an item inside of a housing, rotating the housing in a first direction to create tension, and releasing the tension so that the housing rotates in a second direction and mixes the item.

Proposed is a vertically movable mixer including a container comprising a bottom portion in which a central through-hole is formed, a motor housing coupled to the container under the container, a motor built in the motor housing, a sliding member configured to reciprocally slidably move in a vertical direction through the central through-hole of the container, a rotatable shaft rotatably installed in the sliding member so as to be configured to reciprocally slidably move in the vertical direction in conjunction with the sliding member and axially mounted on a motor shaft of the motor so as to be configured to rotate by rotation of the motor, and a rotatable blade mounted on the rotatable shaft and configured to cut, grind, and mill food contained in the container while rotating and while reciprocally slidably moving in the vertical direction.
