Abstract
A blender jar defines a geometry to impart vertical movement to material being processed in the blender jar, and, alternatively or in combination, improves the horizontal movement to the blended material. By configuring one or more agitators on the floor of a jar, laminar flow or symmetric flow of material around the jar is disrupted. The material is forced in an upward direction in the jar and, therefore, into more frequent contact with the cutter blades rotating in the jar.
Claims18
A blender jar for promoting three dimensional material flow, the jar comprising:
- a floor and a sidewall connected to the floor and extending vertically upwardly from the floor to form a space inside the sidewall and above the floor where material is blended;
- the floor comprises a central opening through which extends a drive shaft;
- a cutter assembly attached to the drive shaft, the cutter assembly comprising a blade that rotates on the shaft inside the blender jar and above the floor, the rotation of the blade defining a blade path;
- wherein the floor comprises an agitator that is closer to the blade path than the remainder of the floor;
- and
- wherein the agitator is curved in a vertical direction relative to the horizontal plane of the blade path.
