Egg Production: Packing

Automated machines sort eggs into separate lines by grade and size, for instance, Grade-A Large. To minimize breakage, eggs are packed in fiber or foam cartons. Each carton is printed with the appropriate grade and size. Lasers burn onto the cartons either an expiration or sell-by date for the stores or a best-by or use-by date for consumers. Sensors guide computer-controlled robotic arms to pick up the cartons on each line, turn them and fill a case.
