Thorough spraying and draining freshly cut produce and the equipment processing it in a one-pass system that uses a dilute solution of chilled ultrapure water and chlorine dioxide or chlorine or both significantly reduces bacterial counts. Raw produce is sprayed as it is conveyed to cutting heads and as the cut pieces fall into a hopper above a conveyor. The conveyed cut produce is vibrated and tumbled while being sprayed from above. At the end of the process, the cut produce is sprayed with potable water and deposited in a dryer basket. Drainage from the equipment is collected and processed through a multi-stage water filtration system to potable quality. The near freezing water temperature, its ultra-purity, and the concentrations of biocides in the sanitizing spray are carefully established, monitored and maintained by a process controller.
