<p>A device for use in a blender comprises a rotatably arranged tool (10) for moving through food to be processed by means of the blender, and a tool cage (20) for partially covering the tool (10). The tool cage (20) is shaped like a hollow cylinder having a longitudinal axis and an inner surface (24) with exclusively non-convex areas, wherein a cross-sectional shape of the tool cage (20) deviates from a circular shape and has at least one protruding area which is outside of an imaginary circle being centrally positioned about the longitudinal axis and touching the inner surface (24) while having a minimum radius. The inner surface (24) of the tool cage (20) may have a triangular shape or a square shape about the longitudinal axis. A dimensionless characteristic value and a range for the value are defined for predicting quality of performance of the device.</p> |
