The report describes the design and performance of two gas-fired rethermalization ovens developed to provide a gas-fired alternative to the electric rethermalization ovens currently used in the cook-chill process. One approach used a power burner while the other approach used an atmospheric burner in an induced draft combustion system. Both fire-tube systems were rated at 90,000 Btu/hr input. The new gas-fired oven was forced convected by a single motor/blower combination operating at 1750 RPM and which circulated 2,500 ft/min of hot air for rethermalization as well as conventional forced convection oven cooking. The unit was designed to accommodate 10 steam table pans, each 12 inches x 20 inches x 2-1/2 inches deep and is modular to permit relatively easy expansion to a 22 pan oven. The overall design and operating parameters were met by heating 150 pounds of macaroni and cheese (10 standard steam table pans, 15 pounds per pan) from 37 F to an average serving temperature of 160 F in 45 minutes; oven preheat times less than 10 minutes; efficiencies of approximately 50 percent; and excellent results when cooking full loads of frozen cherry pies, sheet cakes, and buttermilk biscuits. The version using an atmospheric burner is planned for commercialization by the cooperating manufacturer.
