The D-value for pasteurizing chicken shell eggs that are not refrigerated prior to pasteurization, or shell eggs that are sufficiently tempered to room temperature prior to pasteurization, is less than the D-value for pasteurizing chicken shell eggs that are refrigerated prior to pasteurization. Statistically verified time and temperature pasteurization protocols that produce pasteurized chicken shell eggs to achieve at least a statistical 5-log reduction of Salmonella Enteritidis are therefore possible at lower pasteurization temperatures or lower pasteurization dwell times.
An in-line shell egg pasteurizer has a clean-in-place system. Empty shell egg carriers are placed in the water bath for multiple cleaning cycles. The cleaning solution level is lowered to expose the shell egg carriers and the top parts of the water bath walls. An air perturbation is used to agitate cleaning solution held in the bottom of the water bath and clean heating coils and other components located in the bottom of the water bath. Sprayers (e.g., nozzles, cleaning spray balls, etc...) mounted on a hood over the water bath clean the top parts of the water bath walls and the empty shell egg carriers placed in the water bath.

AUTOMATED WAX SPRAYER SYSTEM FOR CLEAN, WASHED OR PASTEURIZED SHELL EGGS
An automated wax sprayer system for clean, washed or pasteurized shell eggs sprays a heated solution containing water and wax emulsion onto the eggs as they rotate and pass through a conveyer. The temperature of the wax coating on the surface of the egg shells is heated at or above a sanitizing temperature and sprayed on the surface of the egg shells where Salmonella contamination may be present. Salmonella contamination present on the surface of the egg shells is eliminated substantially immediately. Separate flow pumps provide a consistent flow of wax solution to individual nozzles for consistent application of the wax on the entire surface of the eggs.
A shell egg pasteurization system uses radio frequency electromagnetic wave energy to heat the yolk. The radio frequency energy is applied in two stages as the shell egg is rotated and moved through the electric field. The system also has a preheating oven and a downstream albumen heating oven. The combination of heat from the ovens and the radio frequency is sufficient to achieve a 5 log kill of Salmonella Enteritidis throughout the eggs.
Chicken shell eggs pasteurized in a water bath set at a temperature of no more that substantially about 133°F (±0.5°F) result in eggs having measured albumen turbidity normally less than 200 Nephelometeric Turbidity Units.
An edible, aqueous emulsion coating is particularly suitable for coating washed or pasteurized chicken shell eggs to extend shelf life in high humidity climates. The edible, aqueous emulsion coating includes paraffin and carnauba wax as well as hydrophobic means for maintaining the integrity of the dried, emulsion coating over the entire surface of the shell of the chicken egg even when the coated chicken egg is in humid environments having a dew point exceeding 85°F. A suitable hydrophobic means is high-density, food-grade polyethylene.
A batch processing control system for a shell egg pasteurizer controls the time and temperature in which batches of shell eggs are held in a pasteurization bath in accordance with a predetermined pasteurization protocol for designated egg size and start temperature. The predetermined pasteurization protocol is preferably statistically verified to optimize batches of eggs having the designated size and start temperature. The system also includes reporting software that generates daily reports to track each respective batch and verify that the batch has been pasteurized according to the statistically verified protocol.
