How Does an Egg Printer Work?

An egg printer works in a simple, repeatable loop:

1. Eggs are placed on a conveyor (often already in trays).
2. A photoelectric sensor detects each egg as it arrives under the print head.
3. The non-contact head sprays food-grade ink onto the curved shell from a few millimeters away.
4. The coded eggs continue down the line to be packed.

The printer is controlled from a touch screen where you set the date, batch, logo or QR content. Because printing is non-contact, shells are not touched or cracked, and the ink dries in seconds so it will not smudge during packing.
