ABSTRACT:
A blade is provided for use in a blender wherein the blade is to rotate about a vertical axis of rotation. The blade is formed with a central hub portion defining a horizontal plane, and in a preferred arrangement, has four tines extending outwardly from said hub portion with each tine angularly spaced at 90.degree. to two adjacent tines to form two opposed pairs of tines, however, with the tines being arranged asymmetrical to one another. In order to reduce vibration and torque occasioned by the asymmetrical arrangement of the tines, each tine in an opposed pair is formed to be balanced to the other tine with respect to a first product of its mass times a distance of its center of mass from the center of rotation and with respect to a further product of its mass times a distance of its center of mass from the axis of rotation and times a distance of its center of mass from the horizontal plane. Preferably the magnitude of the products for each tine in an opposed pair should be within 1% of the magnitude of the products for the other tine in the pair.
