Egg Collection
In layer facilities, there are two primary methods of egg collection, a) in-line facilities, and b) off-line facilities. In either case, hens lay eggs onto an angled wire floor which rolls the egg toward the front of the cage (floor angle is generally eight to ten degrees) onto a nylon belt. The belt transports eggs out of the house either to the egg processing facility or to a storage cooler. Since the processing facility and cooler remove eggs from the house, based on hourly demand, eggs may reside on the belt for as long as 12 to 14 hours, but most are collected within a few hours post-lay.
The first type of layer facility is the in-line facility. In this facility, eggs move directly from the layer house to the egg processing facility. Once the eggs enter the egg processing center, within minutes to 12 to 14 hours post-lay, they are washed (detergent solution near 100°F, pH 11.0 that removes soil), visual inspected (checked for eggshell problems, cracks, and blood spots), and then graded for packaging. Following packaging, eggs are moved to a cooler room (40-45°F), where they await shipment to retail outlets. Egg producers commonly deliver eggs to retail outlets within one week of lay.
The second type of layer facility is the off-line facility. This facility functions nearly identical to the in-line facility except that the eggs are transported out of the house directly to an egg cooling room. In this method, the eggs remain in the cool room for approximately two to three days, and then they are transported to an egg processing facility via a refrigerated truck. These eggs are treated identically as those from the in-line operations.
