Abstract
A blender system (1) has a container (3) for holding material to be blended. The container (3) has a first portion (2) with blade member assemblies (6, 8). The assemblies (6, 8) are rotationally driveable around axes of rotation (10, 12). The container has a second portion (4) with a guiding surface (18). A cross-section (38) of the guiding surface (18) which encloses said axes of rotation is a convexly shaped closed curve (20). The direction of the cross-sectional curve (20) is continuously varying direction along the perimeter of the guiding surface (18).
