Abstract: A mixer assembly includes a mixer body and a mixer cover coupled to the mixer body. The mixer body includes an inner wall defining a mixing chamber having an inlet and an outlet. The inner wall includes a plurality of protrusions disposed on top of the inner wall that form a plurality of passes therebetween. The mixer body further includes a shell disposed around the inner wall that forms a diluent chamber between the inner wall and the shell. Diluent entering the diluent chamber flows through the plurality of passes and into the mixing chamber for mixing with product entering from the inlet of the mixing chamber. Mixed product exits the mixer body from the outlet of the mixing chamber. The mixer cover includes an angled shelf that closes out the diluent chamber and extends over the plurality of passes such that diluent entering the diluent chamber moves through the plurality of passes along the angled shelf and into the mixing chamber.

Abstract: Methods and apparatus for pumping and dispensing are provided in which a peristaltic pump (16, 64) pumps liquid from a package (12), and may be integrated in a dispenser (10). The peristaltic pump (64) is adapted for improved accuracy, cleaning, and maintenance. Also provided are improved tubes (18) for peristaltic pumping that are coupled to self-sealing dispensing valves (92, 104, 110, 120).
