How they sort eggs?

Eggs are sorted by several factors, including size, quality, and color.

Size

Eggs are sorted by size using a machine called a sizer. The sizer consists of a series of rollers that are set at different heights. The eggs roll down the rollers, and the rollers that they can fit through determine their size. The most common sizes of eggs are small, medium, large, and extra-large.

Quality

Eggs are also sorted by quality. The quality of an egg is determined by a number of factors, including the condition of the shell, the firmness of the yolk and white, and the presence of any blood or meat spots. Eggs that meet the highest quality standards are classified as Grade AA. Eggs that have some minor defects, such as a slightly cracked shell, are classified as Grade A. Eggs that have more serious defects, such as a large crack in the shell, are classified as Grade B or C.

Color

Eggs can be sorted by color, although this is not as common as sorting by size or quality. The color of an egg is determined by the breed of the hen that laid it. Most eggs are white or brown, but some breeds of hens lay eggs that are blue or green.

Process

The process of sorting eggs begins with the eggs being collected from the hen house. The eggs are then brought to a grading station, where they are cleaned, candled, and sorted. Candling is the process of holding an egg up to a light to check for any defects. The eggs are then sorted by size, quality, and color. The sorted eggs are then packed into cartons and shipped to stores.
