Interpretive Summary:

Technical Abstract: A conveyor was added to a model scald tank (6.07 m by 11 cm with 18 cm of water) to move simulated carcasses through the tank. Wooden strips (1.2 by 1.8 cm) were attached to the chain every 15 cm and reached a water depth of 7.5 cm. The conveyor was operated at 140 carcasses per min with wooden strips alone (equal to 5% of tank cross sectional area) or with aluminum plates (5 cm by 10.2 cm, or 26% of tank area) attached to the strips to simulate carcasses. Tank water was air agitated. A computer program modeled dye movement in the tank assuming perfect mixing between adjacent cells 1 cm wide. Simulated carcasses moving through the water increased the effective mixing cell width to 2 cm for the wooden strips alone or to 17 cm for the aluminum plates. Movement of dye through the tank was correctly calculated by the computer model. Key words: scalding, water mixing, dye, broiler
