Six Head Egg Inkjet Printer

Six Head Egg Inkjet Printer

Six print heads, one full 5×6 tray per pass

Model S10-6

The SHICAI S10-6 six-head egg inkjet printer marks a complete 5×6 tray in a single pass — 30 eggs at a time, 20 trays per minute. Each of the six heads covers its own column, so every egg in the tray receives a production date, batch number, farm code or traceability QR code without being handled individually.

Printing is non-contact. The heads stay 2–5 mm above the shell, so nothing presses on the egg and shell strength never becomes a constraint. Food-grade water-based red ink sits on the surface and holds up through grading, packing and cold storage.

Character height reaches 12.7 mm at 600 dpi, which keeps codes readable for both packers and inspection staff. The unit runs on 110V or 220V, connects over USB or HDMI, loads codes straight from a USB flash drive, and ships with Chinese, English, Arabic, Korean, Spanish, French, Russian, Vietnamese and Bengali interface options.

How it works

Three steps, thirty eggs

No sorting, no breaking the tray apart, no second pass.

  1. 1

    Load the tray

    Set a standard 5 × 6 tray on the transport tape. The fixed baffle squares it against the head bar before printing starts.

  2. 2

    Recall the job

    Pick the saved code on the 7-inch touch screen. Farm name, date, lot and QR code are stored as one preset.

  3. 3

    One pass, 30 eggs

    The head bar crosses once at 20 trays a minute. The tray leaves the belt coded and ready to pack.

On the line: the tray runs under the head bar and leaves the belt coded.

In detail

What you are actually buying

The parts of the machine that decide throughput, code quality and how long a changeover takes.

Core mechanism

Six heads mean you never sort a tray

A single-head coder works one egg at a time, so the tray has to be broken down, run through and rebuilt. The S10-6 carries six heads across the width of a standard 5 × 6 tray. All 30 eggs are coded in one pass, and the tray leaves the belt ready to pack.

Controls

Set the job once, then leave it alone

The 7-inch colour touch screen holds the job on the machine, so the operator picks a saved code instead of rebuilding it on a laptop. A shift change is a tap, not a setup.

Food safety

Food-grade ink, and nothing touches the shell

The S10-6 uses food-grade water-based red ink. The head bar runs 2–5 mm above the shell, so the egg is marked without contact and without a pad to clean. Because nothing presses on the shell, surface texture and shell colour do not change the result.

Built to be serviced

Everything an operator needs sits on the outside

The tray baffle squares the tray before printing, the transport tape carries it at line speed, and the cartridges lift out by hand. Height adjustment and the conveyor switch sit at the front of the frame, so a changeover does not need a technician.

Hourly figures are calculated from the speed the factory publishes, on a standard 5 × 6 tray (30 eggs). Real throughput follows your line speed, loading and stoppages. A dash means the factory has not published that figure — ask us and we will confirm it against your line.

Questions

Before you ask

What Is the Capacity of a Six-Head Egg Printer?

A six-head egg printer codes a full 30-egg tray in one pass and is the workhorse of packing lines. On a standard 30-egg tray it runs 20 trays per minute — 600 eggs per minute, or about 36,000 eggs per hour. Each food-grade cartridge prints tens…

Single-Head vs Multi-Head Egg Printer

A single-head printer marks eggshells one at a time or in a row; affordable and fine for low volume. A multi-head (commonly 6-head) printer codes a full tray of 30 eggs in one pass, multiplying throughput. Six independent heads can even print different content per row…

What Is the Tray Speed of an Egg Printer?

Automatic egg coders typically run at about 20 trays per minute on a 30-egg tray — 600 eggs per minute, roughly 36,000 eggs per hour. Note that 20 trays/min and 1,200 trays/hour describe the same machine, so quoted figures can look different without being different. Tray…

Why Is Non-Contact Printing Important for Eggs?

Eggshells are thin and brittle, and sizes vary. Non-contact printing sprays ink from a few millimeters above the shell, so the head never touches the egg. This eliminates the cracking and bruising that contact stampers can cause. Non-contact coding also prints cleanly on the curved, porous…

Read the full answer
Is Egg Printer Ink Food-Grade and Safe?

Yes, provided you use food-grade ink formulated for eggshells. Egg shells have micro-pores, so ordinary industrial ink could migrate inward and contaminate the egg. Food-grade ink is designed to stay on the surface and be non-toxic. Look for inks that meet FDA (USA) and EU/EFSA food-contact…

Read the full answer
How Does an Egg Printer Keep Up with a Grader?

To keep up with a grader, the coder must match the grader's eggs/min and share speed and trigger signals so printing fires exactly when eggshells arrive. Mounting the coder on the grader's conveyor (or feeding roller) makes coding inline. Multi-head designs code whole trays in the…
