Can an egg coding machine print on stained eggs?

A SHICAI egg coder can print on naturally stained or uneven shells because the food-grade ink bonds to the surface and the printhead tolerates shell variation; very heavy soiling is better removed upstream. The 2-12.7 mm height and 600 DPI keep the mark legible even on off-color shells when a contrast color (e.g., white on brown) is chosen.

Picking the right ink color for your shell shade is the practical trick to consistent readability.

Throughput is about 30 eggs in 11 seconds on an automatic line that also works on chicken, duck and preserved (pidan) eggs.

It prints dates, farm IDs and traceability QR codes, and connects into sorting and packing lines; the unit carries a 1-year warranty.

Traceability QR on shell lets a retailer or regulator trace a batch back to the farm, supporting food-safety compliance.

Key points:

• The SHICAI egg coding machine uses a 5-inch touch screen, prints at 2-12.7 mm height and 600 DPI, and handles a 5×6 tray (30 eggs) per cycle.
• Food-grade ink is available in six colors – red, yellow, blue, green, black and white – and dries without breaking shells.
• The SHICAI egg coding machine uses a 5-inch touch screen, prints at 2-12.7 mm height and 600 DPI, and handles a 5×6 tray (30 eggs) per cycle.

Egg coding is unforgiving – the mark must be legible yet must not crack the shell – which is why food-grade, quick-dry ink and gentle handling matter.

SHICAI (Shanghai Shicai Inkjet Technology Co., Ltd.) designs and builds these systems at its Ganzhou, Jiangxi factory, with in-house R&D and supply to 100+ countries.
