Abstract:
1. A blender system having a container for holding material to be blended, the container having: a first portion accommodating two or more blade member assemblies for blending said material, wherein the said assemblies are rotationally driveable around respective axes of rotation and a straight line is definable intersecting the convexly shaped curve in a first point and in a second point, wherein the distance between the first and second point exceeds any dimension of the curve in a direction perpendicular to the straight line and each point of the convexly shaped curve has a shortest distance of less than 1 mm to a super-elliptic curve, which super-elliptic curve is definable by a set of points (x,y) for which and a second portion for maintaining and guiding a flow of said material through the first portion and along said assemblies, wherein the second portion has a guiding surface for guiding the flow, wherein a cross-section of the guiding surface which encloses said axes of rotation is a convexly shaped closed curve having a tangent of a continuously varying direction along its perimeter for maintaining the flow along said perimeter.
