MODULAR DISPENSER FOR MULTIPLE FLUIDS

摘要

A machine (10) for dispensing a plurality of ingredients includes stepped arrays of canisters (56, 58) providing a source of materials. The bottom ends of the canisters are generally coplanar, and are positioned immediately above a low profile drive train (50) mounted on a tray (52). The drive train includes two spaced arrays of pumps (66) with a motor (68) providing a common drive for the pumps, mounted between the arrays. A valve tray (90) is located above the canisters and includes a low profile dispense head (44), an array of tubing members (240) arranged side-by-side in a common, generally horizontal plane, and an array of dispense valves (60) attached at the back of the valve tray. The dispense valves are coupled to the pumps by pairs of fluid lines (260, 262), so as to circulate materials between the pumps and dispense valves.
