Abstract

A tool that is attachable to an electrically driven stand mixer and configured, when suspended into a bowl and driven in planetary motion by the stand mixer, to perform a mixing operation that involves folding ingredients together without substantial expulsion of air from the mix. The device aims to automate the folding action by providing a food mixing arrangement in which a tool having a wing-like volute blade is suspended by its shaft from a drive outlet of the stand mixer and executes a planetary motion within a mixing bowl. The blade is twisted along its length and has curved surfaces formed to gently lift and turn ingredients to be mixed in the bowl so as to simulate a gentle folding action similar to that achieved manually by an experienced cook.

First claim

1 .- 11 . (canceled)

12 . A food mixing arrangement incorporating a tool comprising a wing-like volute blade adapted for suspension by a shaft from a drive outlet of a stand mixer capable of causing the blade to execute a planetary motion within a mixing bowl, whereby the shaft rotates in one direction around its own axis while being bodily moved in the opposite rotational direction about another axis parallel to, but offset from, that of the shaft; wherein curved surfaces of the blade are formed to gently lift and turn ingredients to be mixed in the bowl.

13 . An arrangement according to claim 12 , wherein the blade is elongate and extends outwardly from the shaft, twisting along its length.

14 . An arrangement according to claim 12 , wherein a leading edge of the blade is thinned relative to the remainder of the blade.

15 . An arrangement according to claim 14 , wherein the blade thickens progressively from the leading edge towards a thicker central column providing strength for the tool.

16 . An arrangement according to claim 12 , wherein the volute blade comprises a part spiral form.

17 . An arrangement according to claim 16 , wherein the part spiral comprises 0.5 turn or less about the axis of the shaft.

18 . An arrangement according to claim 17 , wherein the part spiral comprises 0.45 turns about the axis of the shaft.

19 . An arrangement according to claim 12 , wherein the volute blade comprises one or more spiral turns.

20 . An arrangement according to claim 12 , wherein the wing-like blade further comprises an upper shoulder portion extending outwardly from the vicinity of the axis of the shaft and shaped to return to the mixture ingredients tending to move upwardly within the bowl.

21 . An arrangement according to claim 12 , wherein the wing-like blade is formed with a compound curvature and tilt to simulate manual folding of ingredients using a spoon.

22 . An arrangement according to claim 12 , wherein a leading edge of the tool supports a flexible elastomeric material.
