Method of generating a frothed milk composition
First Claim
1. A method of generating a frothed milk composition comprising:
- housing a milk composition in an open vessel,immersing a planar agitator blade in said milk composition androtating said agitator blade in said milk composition, about a longitudinal axis, at a high speed effective to entrain air in said composition and produce a frothed milk product,said agitator blade having a pair of opposed smooth, flat faces extending perpendicularly of said longitudinal axis, and a smooth cylindrical outer wall between said opposed faces,said outer wall having a circumferential length significantly greater than the distance between said opposed faces,wherein said milk composition consists of a flavouring and skim milk and said frothed milk composition is a milk shake.

Abstract
A device and method for generating a frothed milk product from a milk composition employs a planar agitator blade having opposed, smooth flat faces extending perpendicularly of a longitudinal axis of rotation, and a smooth cylindrical outer wall between the flat faces; the outer wall has a circumferential length significantly greater than the distance between the opposed faces. The device produces thick milk shakes even when employing no-fat or low fat milk or yogurt in place of normal homogeneous milk. A blender having a blender blade with opposed flat surfaces and a smooth cylindrical outer blade wall, and having ribs extending radially outwardly along the opposed surfaces, serves to puree fruit or vegetable morsels with the milk composition, to produce fruit or vegetable flavored milk shakes.

6. A method of generating a fruit or vegetable flavoured milk shake comprising:
-
i) housing a mixture of a milk composition and morsels of fruit or vegetable in an open vessel, ii) immersing a blender blade in said milk composition, iii) rotating said blender blade in said mixture, about a longitudinal axis, at a speed effective to puree said morsels, iv) removing said blender blade from the resulting flavoured mixture of the milk composition and the pureed morsels, v) immersing a planar agitator blade in said flavoured mixture, vi) rotating said agitator blade in said flavoured mixture about said longitudinal axis, at a high speed effective to entrain air in said flavoured composition and produce a flavoured milk shake; and
wherein;a) said blender blade having a pair of opposed flat blade faces extending perpendicularly of said longitudinal axis, and a smooth cylindrical outer blade wall between said opposed faces, said opposed faces comprising an upper face and a lower face, b) a first plurality of rounded ribs on said upper face, said first plurality extending radially of said longitudinal axis, each rib terminating in a bulbous member extending from an outer end of the rib, over the blade wall and the outer edge of the lower face; the bulbous members of said first plurality being in circumferentially spaced apart relationship about said blade wall; c) a second plurality of rounded ribs on said lower face;
said second plurality extending radially of said longitudinal axis, each rib terminating in a bulbous member extending from an outer end of the rib over the blade wall and the outer edge of the upper face;
the bulbous members of said second plurality being in circumferentially spaced apart relationship about said blade wall;d) said agitator blade having a pair of opposed smooth, flat faces extending perpendicularly of said longitudinal axis, and a smooth cylindrical outer wall between said opposed faces; and e) said outer wall having a circumferential length significantly greater than the distance between said opposed faces. - View Dependent Claims (7, 8, 9, 10)
