Egg Cooling Characteristics in Commercial Egg Coolers

Abstract
Studies were conducted to examine how cartoning, casing and palleting methods affect the cooling rate of eggs in commercial egg coolers during 24 and 72 hour periods. Cooling rate was found to be a function of how readily air interacted with individual cartons of eggs. Eggs in wire baskets were found to cool from an original temperature of 80°F to the egg cooler temperature of 45°F in approximately 48 hours, whereas eggs in cardboard cases required nearly one week. Egg cartoning material (styrofoam vs. wood-pulp) had little effect on the rate of cooling.
