ABSTRACT:
A device for mixing an individual serving portion of powdered food product with liquid includes an upwardly open container having a wide screw neck and a cover formed to threadably mount on the neck to form a sealed chamber within the container. A motor is mounted on the top of the cover and drives a rotatable shaft which, when the cover is secured on the container, extends downwardly from the cover into the container chamber along a central axis thereof. The container is generally circular in horizontal cross-section and two spaced apart pairs of blades are fixed to the shaft for rotation therewith. For use, powdered food product and liquid are placed in the container, the cover is secured on the container, and the motor is actuated to cause rotation of the shaft and blades. The blades are uniquely pitched so that their rotation, combined with the circular shape of the container, creates a vortex in the liquid in the container during mixing. This induces air to be entrained in the mixture of powdered food product and liquid in the form of air bubbles, which gives the end product a "whipped" consistancy and increases its total volume.
