ABSTRACT

This chapter examines familiarity with flow diversion devices, specifically, flow diversion devices used on systems producing ultrapasteurized and commercially sterile products. A flow diversion device designed for aseptic processing may not look like the common pasteurizer type, but it is the physical means to prevent under-processed product from being packaged. The flow diversion device is widely recognized by the processors of milk and milk products. A high-temperature, short time system effectively operates with the ability to cycle in and out of forward flow. Most systems allow diversion of product only once when using post cooler flow diversion. A flow diversion and product routing design can be built that allows for ultrapasteurized and pasteurized production under the Pasteurized Milk Ordinance and, with only minor needs for additional valves, meets the recommendations of the process and packaging authorities. Packaging authority is the National Food Laboratories, a division of the National Food Processors Association.
