355nm uv laser with water cooling system marking eggs
Sep 15 , 2021
Nowadays, consumers are paying more and more attention to the shelf life, and they have to look at everything they buy, but many people don't know the shelf life of eggs. As an important food, we eat eggs every day. The shelf life is also very important. Almost everyone thinks that as long as the eggs are not bad, they are good, and they don’t pay much attention to the shelf life.
Experts have proved that the lower the temperature, the longer the shelf life of eggs, the higher the temperature, the shorter the shelf life, but the longest does not exceed 40 days. The nutritional content of the egg will change after the expiration date and lose its edible value. However, we can't find anything by looking at the shell. This requires printing its label on the egg, such as the date of production, the manufacturer’s trademark, the barcode, and the two-dimensional Code and other information.

The eggs are marked with ink coding and laser coding, but the ink coding is easy to wear and tamper with, and the contact processing is easy to crush the fragile eggs, and the eggs are arc-shaped, which is not easy to master manually. Since the ink is harmful to the human body, this printing code cannot be implemented.
Laser marking eggs expose the deep material through the evaporation of the surface material, showing the barcode, QR code, production date, etc. to be etched, which can realize automatic coding, serial number, date, etc.; it will never fade after marking;. Non-contact processing, no damage to the eggs; non-toxic, no environmental pollution; ultra-precise and fine graphic marking can be carried out, and processing is fast; the flying marking system is equipped with an assembly line device, which is more efficient and faster.
