Abstract
A food processor wherein a shaft which extends into the interior of a bowl is driven by an electric motor employs a whipping tool having a hub which receives torque from the shaft, either directly or through the medium of an adapter, and a disc-shaped portion. The underside of the disc-shaped portion is immediately adjacent to the upper side of the bottom wall of the bowl and has ribs separating radially extending channels each having an inlet in the region of the hub and one or more outlets at the periphery of the tool. When the tool rotates, the inlets draw air or receive air from a system of passages, and the channels discharge the thus admitted air into the material (such as cream, egg whites or mayonnaise) which gathers at the periphery of the tool so that the material is thoroughly mixed and is also whipped by admission of finely atomized air. The tool can process large or very small quantities of foodstuffs without changing its RPM. The inlets can be defined by hood-shaped upwardly extending portions of the tool or they may constitute openings in the flat disc-shaped portion of the tool.
