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 system for providing a single serving of a frozen confection, wherein the system comprises a pod comprising at least one ingredient for providing a single serving of a frozen confection; the system cools the pod; the system introduces water into the pod; the system simultaneously stirs the contents of the pod while scraping at least one wall of the pod to prevent a build-up of the frozen confection on the at least one wall of the pod; and the system ejects the frozen confection out of the pod.

A carbonated beverage apparatus includes a freezing cylinder for receiving a mixture, and a stirring pusher disposed inside the freezing cylinder for pushing and mixing the mixture from an inlet of the freezing cylinder to an outlet thereof in a spiral manner, wherein the mixture is removed from the inner wall of the freezing cylinder radially back into a center portion of the freezing cylinder by the stirring pusher.

A microwavable container for use in a microwave oven that includes provisions to stir or mix food during microwave cooking. This mixing action is achieved by utilizing the motor of the microwave oven. Such mixing provides more even heating of food, and reduces the need to stop the microwave oven to manually stir food.

A fluid-agitating tank assembly is disclosed. The tank assembly includes a tank filled with a fluid, and an agitator disposed in the tank so as to be at least partially immersed in the fluid and supported by the tank in a rotatable manner about an axis. The agitator includes a double helix disposed in an upper volume of the tank and adapted to act on the fluid to transform unidirectional rotation of the agitator about the axis into a bidirectional movement of the fluid in the tank towards bottom and top portions of the tank, and at least one rotary blade projecting transversally from the axis, disposed in a lower volume of the tank, and rotating about the axis to move the fluid towards at least one lateral outlet of the tank.

A portable concrete mixer includes a frame, a hopper, coupled to the frame, for receiving therein dry commercially available prepackaged concrete mixes containing gravel aggregates, a chute coupled to the hopper, a water supply system that supplies water to the chute, a motor, and an auger coupled to and rotated by the motor. The auger includes a shaftless helical auger body extending from the hopper into the chute via an aperture in the hopper. The shaftless helical auger body has an interior volume and a plurality of fingers extending from the auger body into the interior volume. The shaftless helical auger body has an uneven pitch such that a second portion of the helical auger body in the chute has a greater pitch than a first portion of the helical auger body in the hopper.

A high shear mixing device is provided. The high shear mixing device comprises a first screw kneader and a second screw kneader; a first rotation driving mechanism configured to rotate the first screw kneader and a second rotation driving mechanism configured to rotate the second screw kneader; a revolution driving mechanism including the first rotation driving mechanism and the second rotation driving mechanism rotatably installed therein; a driving mechanism body including the revolution driving mechanism installed therein; and a mixing tank. Each of the first screw kneader and the second screw kneader comprises a shaft having one end connected to the rotation driving mechanism; and three or more blades having one end fixed to the shaft and having a helically curved body along the longitudinal direction of the shaft, and the first and second screw kneaders rotate in opposite directions with their blades overlapping each other.

Provided is an oil-in-water-type emulsion composition which can be produced by directly emulsifying an organopolysiloxane having a high polymerization degree, contains substantially no oversized particle, and has a small average particle size. A method for producing the oil-in-water-type emulsion composition using a vertical batch mixer is also provided. The oil-in-water-type emulsion composition is an emulsion comprising (A) an organopolysiloxane having an overall viscosity of 1,000,000 mPa.Math.s or more or having plasticity or a mixture thereof, (B) a surfactant, and (C) water. Component (A) is emulsified in water by the action of component (B), the average particle size of emulsion particles falls within the range from 0.1 to 7.5 ?m, and the content of emulsion particles each having a particle size 10 times or more larger than the average particle size is less than 5.0 vol %.
