An axial impeller has blades formed from sheet metal blanks that are configured from taking a desired impeller blade and mathematically unwinding the blade to its flat counterpart. Preferably, the impeller blade is formed from a single rolling operation. The result of a thin, elongate blade, preferably having a trailing edge that defines a helix with rearwardly skewed, forwardly raked blades, provides an efficient impeller having good anti-ragging properties.

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.

Apparatus for cooking foods includes an external container, an internal container, open at the top, a heating device and a rotating mixing device. The mixing device is selectively removable and comprises at least one mixing blade driven by the rotation motion.

A kneading device 1 comprising an inner cone 2 and an outer cone 3, wherein the inner cone 2 and the outer cone 3 defines a space 4 in between the inner cone and the outer cone; from a horizontal plane the inner cone 2 inclines and forms an angle ic; from the same horizontal plane the outer cone 3 inclines and forms an angle oc; where the inner cone 2 has an opening in a bottom of the inner cone 2; where both the inner cone 2 and the outer cone 3 continue vertically in an inner extension 5 and an outer extension 6, respectively, wherein a space in between the inner extension 5 and the outer extension 6 is a gap E; where scraping wings 7 extend from a center portion 8 of the kneading device 1 and through the inner cone 2 and the outer cone 3 and towards, but not fixated to, an inner wall 9 of the outer cone 3; and where the outer cone 3 inclines more than the inner cone 2, when viewed from the horizontal plane, so that angle oc>angle ic.

Apparatus for cooking foods includes an external container with protective lid of the openable type, and an extractable internal container. The internal container is open at the top and has a base wall and at least one lateral wall, a heating device connected to a possible mean to transfer the heat generated toward the surface of the internal container and a mixing device reciprocally mobile with respect to the internal container.

A hand blender containing a blade arrangement for a domestic appliance for cutting and comminuting food containing a rotatable blade with a hub which lies at a center of rotation of the blade for receiving a shaft. The blade includes at least one cutter which extends radially and which has a cutting edge that lies on a front side in the rotational direction and defines a circular cutting zone when circulating. The blade also includes a milling rib which protrudes upwards from the blade in an axial direction and is oriented so as to produce a milling effect when circulating and defines a corresponding milling zone that extends from the hub to the cutting zone of the cutter.

A method of producing a granular aggregate in which wet granulated substances including active material particles, conductive material particles, a binding agent for binding the active material particles and the conductive material particles, and a solvent are aggregated includes adding a binding agent solution in which the binding agent is dissolved in the solvent to the active material particles having a solvent absorbing property, mixing the binding agent solution and the active material particles such that a primary granular aggregate in which granulated primary granulated substances are aggregated is produced, and mixing the conductive material particles into the primary granular aggregate and producing a granulated granular aggregate.

A radially conveying stirring device with at least one stirring element hub configured to rotate about a rotational axis, with at least one stirring blade and with at least one carrier arm connecting the stirring blade to the stirring element hub, wherein there is at least one half-line which starts from the rotational axis, goes through a center of mass of a connecting surface area of the carrier arm to the stirring element hub and is free from intersection points with the stirring blade, and wherein the stirring blade features at least one beveling dividing the stirring blade into at least two stirring blade sections, wherein the carrier arm is embodied at least substantially L-shaped, wherein the beveling is arranged at least substantially in parallel to the rotational axis.

A blending appliance is provided including a motorized base, a blending container, and a blade assembly fitted into an opening of the blending container and rotatably coupled to the motorized base when the blending container is mounted on the motorized base. The blade assembly includes a lower blade element disposed on a spindle performing blending operations on ingredients at a lower end of the blending container; and an upper working element disposed on a shaft spaced apart from the lower blade element, and including an upper working portion and a lower working portion spaced apart from the upper working portion. The upper working portion acting to reduce cavitation in the lower blades element during the blending process.

The invention relates to an agitator device having a static unit and a rotational unit which is in the form of an agitator shaft and, in an assembled state, forms together with the static unit at least one common fluid channel for a fluid. It is proposed that a flow cross-section of the fluid channel, viewed along a main course of flow, is at least substantially constant at least in a coupling region between the static unit and the rotational unit.
