Spiral-type kneading machine with a non-rotating bowl, for the preparation of flour-based mixtures

摘要

A spiral-type kneading machine for the preparation of flour-based mixtures comprises a non-rotating circular bowl (4) and a spiral-shaped kneading tool rotatable inside the bowl. The spiral-shaped kneading tool has its axis (12) substantially coincident with the axis of the bowl (4) and occupies substantially the entire space contained within the bowl. The tool cooperates with a fixed member (19) projecting upwardly from the bottom of the bowl and spaced from the central axis thereof.
