Oem Automatic Egg Printing Machine
OEM Automatic Egg Printing Machine
This equipment applies variable information such as production dates, batch numbers, or brand graphics directly onto eggshells using a food‑grade drop‑on‑demand inkjet system. It is designed to sit upstream of grading or packing conveyors, eliminating the need for separate labeling stations and reducing handling steps.
Working Principle
A synchronized conveyor transports eggs past a print head array containing piezo‑actuated nozzles. Each nozzle ejects picoliter‑scale droplets of UV‑curable or water‑based edible ink onto the shell surface. A vision sensor detects egg orientation and triggers the print head to align the image, while a low‑intensity UV lamp or heated air dryer fixes the ink within milliseconds.

Typical Applications
Egg producers require traceability and branding without compromising shell integrity. The printer integrates into high‑speed grading lines where eggs travel at 0.5 m/s, delivering legible codes that survive washing, transport, and retail display. Because the process is non‑contact, there is no mechanical stress on the shell, reducing breakage rates compared with adhesive label application.
Customization Options
- Conveyor speed range adjustable from 0.2 m/s to 0.8 m/s to match line capacity
- Number of print heads configurable from 1 to 4 for multi‑lane or dual‑side printing
- Ink colour selection (black, red, blue, or custom food‑grade pigments)
- Integration kits for existing PLC platforms (Siemens, Allen‑Bradley, Mitsubishi)
- Software package for variable data import (CSV, XML) and real‑time job switching
Quality Assurance and Maintenance
All contact surfaces are made of stainless steel 304 or food‑grade polymers, enabling routine cleaning‑in‑place (CIP) with mild alkaline solutions. The ink system includes a sealed cartridge with a built‑in filter to prevent nozzle clogging, and a self‑diagnostic routine alerts operators to drop‑out or viscosity shifts. Preventive maintenance intervals are typically 500 hours of operation, primarily involving print head wipe and ink line flush.
Frequently Asked Questions
A: Yes, the mask and nozzle offset are adjustable via the HMI to accommodate small (quail) to large (jumbo) eggs without mechanical changeover.
Q: What information is required for a quotation?
A: Required data include target line speed, egg diameter range, desired print content (static vs. variable), and any existing control system protocol.
Q: How is ink safety verified for food contact?
A: The supplied ink holds FDA 21 CFR 175.300 compliance for indirect food contact, and safety data sheets are provided with each shipment.
Q: What is the typical lead time for a standard unit?
A: Lead time varies with configuration but generally falls between 8‑10 weeks after receipt of purchase order and technical clarification.
