A process for making stable and uniformly dispersed oil-in-water beverage emulsions is provided. The process comprises combining an oil mixture and an aqueous mixture to form a beverage pre-emulsion; in-line mixing of the beverage pre-emulsion; and homogenizing of the beverage pre-emulsion to form a stable and uniformly dispersed beverage emulsion.

Method and apparatus for making beverages

The present invention is a process for preparing high concentration polyvinyl alcohol (PVA) aqueous mixtures, wherein the PVA solid concentration is at least 14% in the mixture.

High concentration agitation of PVA polymer powders

The invention provides an agitated vessel for producing a suspension of solids in liquid with uniform concentration. The vessel comprises a vertical cylindrical tank having sidewalls and a bottom with inclined surfaces forming an interior for holding a suspension of solids in liquid; means for feeding solids and liquid to the tank; a plurality of stationary baffles disposed in the interior of the tank and vertically extending the length of the tank; a rotating shaft vertically installed at the center of the interior of the vertical cylindrical tank; a single turbine impeller with vertical blades radiating from the rotating shaft, the lower edges of the blades being contoured to match the slope of the inclined surfaces of the bottom and positioned so that the lower edge of the impeller is close to the bottom; and an exit port. The agitated vessel achieves uniform concentration of suspensions at lower power requirements than traditional designs and in a low shear environment. The vessel is particularly good for handling floating solids and minimizing damage to friable products.
