System and Method of Cleaning and Sanitizing a Tea Brewing/Dispensing System

摘要

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.
