Development of a Self-Powered Food Sanitation Center
Abstract
The present Food Sanitation Center (FSC) relies upon either the non-powered M2 gasoline burner or the electrically powered MBU logistics-fuel burner. Because of the open burners, it is inefficient and uncomfortable to operate. Various approaches to heating the sanitizing sink and rinse water of a Self-Powered FSC (SP-FSC) were investigated including direct heating of the sanitizing sink by a burner, indirect heating of the sink by an external fuel-fired hydronic heater, and heating the sink by steam injection. Various diesel-fired steam/water heaters and burners were evaluated. The final approach consisted of a lightweight logistics-fueled boiler capable of generating 44 lb/hr of low-pressure steam at 80% combustion efficiency with an integral thermoelectric generator that supplies sufficient electricity (40 W) for operating its burner and the electric water pump. The burner-base used is the bottom portion of an Army H-45 logistics-fueled space heater. The SP-FSC employs a shallow wash sink that provides a work surface and 110 degrees Fahrenheit water spray for manual cleaning of cookware. Items are rinsed with a 140 degrees Fahrenheit hot water spray and sanitized by immersion in a tank that is maintained at a minimum temperature of 170 degrees Fahrenheit by direct steam injection.
