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.
