Abstract: A mixing apparatus 1 comprising a chamber 12 with at least one inlet 16 allowing entry of a solute and a liquid solvent, at least one outlet 52 allowing exit of a solution of said solute and solution, and at least a separator 22 having at least one generally upwardly facing surface 40 and one generally downwardly facing surface 38a, wherein said surfaces define a passageway 50 allowing the solution of the solute and the solvent to pass through and out of the chamber 12, and wherein undissolved solute is descendable along the generally upwardly facing surface 40a.

Abstract: An apparatus 20 for mixing a solute with a solvent is described. The apparatus 20 includes a mixing chamber 12 for a solute and solvent and in which the solute and solvent are moved via a pump 18 and tubes (68a, 68b, 68c and 70). The chamber 12 also contains a divider 80 which, when occupying a first position (“U”), substantially divides the chamber 12 into at least two portions.
