Abstract: A caustic recovery arrangement for a clean-in-place system permits recovery of the caustic solution used for cleaning sanitary liquid-food processing equipment. A recovery tank receives the caustic aqueous solution and entrained solids. The caustic recovery tank has an upper barrel portion and a lower conic portion. The caustic solution remains in the recovery tank for about eight hours to allow the solids to settle out into the conic portion. A solution drain conduit at a lower end of the barrel portion connects to a caustic recovery line with a pump that feeds the recovered solution back to a main caustic supply tank. A solids drain conduit leads from an outlet at the bottom end of the conic portion of the caustic recovery tank to a solids receptacle so that the solids can be recovered for use, e.g., as animal feed or as fertilizer.

Abstract: A technique for cleaning a tea concentrate brewing mechanism including heat exchanger tubing and concentrate receptacles employs a safe and effective aqueous chlorine dioxide solution. A chemical dispensing unit employs a venturi body that mixes a sodium chlorite sanitizer with a weak-acid activator injected into the water flow. Preset water-flow rate metering regulation draws in equal amounts of sanitizer and activator. The chemicals are made up in respective concentrations so that the same volume is required of each one. The cleansing solution may be flowed through the brewing mechanism or sprayed on surfaces to be cleaned.
