Abstract
Abstract An apparatus for mixing and vending beverages made from a mixture of a water soluble powder admixed with granulated sugar or other non-readily dissolvable sweetener agent and cold water. The apparatus includes a powder dispensing assembly and water dispensing assembly each discharging predetermined quantities of powder and water into a pre-mixing chamber and thence to a final mixing chamber which includes an agitating blade. Disposed in the chamber is a helically wound wire member which serves to shift the undissolved powder and sugar back to the inlet end of the chamber to be mixed by the agitator blade for blending with the water.
