Pressure Relationships in the Regenerator of an Egg Pasteurizer

Abstract

SUMMARY –In current egg pasteurization practice, the pressure of raw egg is greater than that of pasteurized egg in the regenerator. Any leakage could contaminate the processed egg. To solve this problem, a commercial pasteurizer was operated with the metering pump located between the regenerator and heater sections and a centrifugal booster pomp employed to prevent cavitation in the regenerator. The method was successful. The pasteurized egg was under a greater pressure than the raw egg in the regenerator for the 4 products studied.
