Question 1

How many eggs per minute can a commercial egg printer handle?

Accepted Answer

A commercial SHICAI egg printer handles about 30 eggs in 11 seconds per tray cycle &#8211; on the order of 160+ eggs per minute in continuous operation. That rate is sized for grading and packing lines rather than small farm bench use, where a handheld might suffice instead. If your volume is far lower, a handheld or desktop coder may be the simpler, cheaper fit. It prints dates, farm IDs and traceability QR codes, and connects into sorting and packing lines; the unit carries a 1-year warranty. 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&#215;6 tray (30 eggs) per cycle. Traceability QR on shell lets a...

Question 2

What is an egg coding machine?

Accepted Answer

An egg coding machine prints dates, farm IDs and traceability codes directly on eggshells using food-grade ink, without cracking them. The SHICAI egg coder uses a 5-inch touch screen, prints at 2-12.7 mm and 600 DPI, and handles a 5&#215;6 tray (30 eggs) per cycle on an automatic line. It turns a manual stamping step into part of grading and packing, raising throughput while keeping shells intact. 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&#215;6 tray (30 eggs) per cycle. Food-grade ink is available in six colors &#8211; red, yellow, blue, green, black and white &#8211; and dries without breaking shells. Egg coding is unforgiving &#8211;...

Question 3

How does an egg printer apply codes without breaking eggs?

Accepted Answer

The SHICAI egg printer applies the code with a gentle, non-contact inkjet jet and a tray that holds each egg steady, so the shell is never pressed or struck. Food-grade ink dries fast on the curved surface, and the automatic handling avoids the cracking risk of manual stamps or rollers. Because nothing squeezes the egg, breakage stays at normal line levels rather than rising from the coding step. Food-grade ink is available in six colors &#8211; red, yellow, blue, green, black and white &#8211; and dries without breaking shells. Throughput is about 30 eggs in 11 seconds on an automatic line that also works on chicken, duck and preserved (pidan) eggs. Egg coding is unforgiving &#8211; the mark must be...

Question 4

What ink is safe for coding eggs (food grade)?

Accepted Answer

SHICAI egg coding uses food-grade ink, available in six colors &#8211; red, yellow, blue, green, black and white &#8211; that are safe for direct contact with the shell and dry without penetrating or weakening it. The ink is chosen specifically for eggs, not a general industrial formula. Color choice also helps graders and retailers read the mark against different shell shades. 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. Linking the coder to the packing line turns coding from a manual step into part...

Question 5

How fast can an egg coding machine print?

Accepted Answer

A SHICAI commercial egg coding machine prints about 30 eggs in 11 seconds on its automatic tray cycle &#8211; roughly 160+ eggs per minute in steady operation. That throughput covers grading and packing lines without becoming the bottleneck. Speed holds because coding is inline with handling; the limit is usually tray feed, not the printhead. It prints dates, farm IDs and traceability QR codes, and connects into sorting and packing lines; the unit carries a 1-year warranty. 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&#215;6 tray (30 eggs) per cycle. Linking the coder to the packing line turns coding from a manual step into part of...

Question 6

Can egg printers print traceability QR codes?

Accepted Answer

Yes. The SHICAI egg coder can print traceability QR codes on the shell, so a retailer or regulator can scan a batch back to the farm, pack date and grade. At 600 DPI the QR stays scannable on the curved surface, supporting food-safety and recall traceability. A shell QR is especially useful where regulation or buyers demand farm-level provenance. 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&#215;6 tray (30 eggs) per cycle. Food-grade ink is available in six colors &#8211; red, yellow, blue, green, black and white &#8211; and dries without breaking shells. Traceability QR on shell lets a retailer or regulator trace a batch back...

Question 7

Do egg coding machines work on chicken and duck eggs?

Accepted Answer

Yes. SHICAI egg coders work on chicken, duck and even preserved (pidan) eggs, adjusting for size and shell via the tray and print settings. The food-grade ink and gentle handling apply across these types, so a single line can code mixed poultry output. If you run multiple egg sizes, confirm the tray configuration covers your range before install. Food-grade ink is available in six colors &#8211; red, yellow, blue, green, black and white &#8211; and dries without breaking shells. Throughput is about 30 eggs in 11 seconds on an automatic line that also works on chicken, duck and preserved (pidan) eggs. Traceability QR on shell lets a retailer or regulator trace a batch back to the farm, supporting food-safety compliance....

Question 8

How is an egg coder integrated into a packing line?

Accepted Answer

An SHICAI egg coder integrates into the sorting and packing line as an inline station: eggs are conveyed or tray-fed, coded, then graded and packed without a separate manual step. The 5-inch touch screen sets the message and tray, and the unit links into the line&#8217;s throughput rather than stopping it. Treating coding as a line station &#8211; not a bench job &#8211; is what lifts throughput and consistency. 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. Egg coding is unforgiving &#8211; the mark...

Question 9

What print resolution do egg coders need?

Accepted Answer

Egg coders need enough resolution for a readable date and a scannable code on a small, curved surface &#8211; SHICAI uses 600 DPI, which keeps both text and QR sharp on the shell. Higher than needed adds cost; lower risks unreadable marks at grading speed. For QR specifically, 600 DPI plus correct quiet zone is what makes the shell code scan reliably. It prints dates, farm IDs and traceability QR codes, and connects into sorting and packing lines; the unit carries a 1-year warranty. 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&#215;6 tray (30 eggs) per cycle. Egg coding is unforgiving &#8211; the mark must be...

Question 10

Can I print dates and farm IDs on eggs?

Accepted Answer

Yes. The SHICAI egg printer applies pack dates, best-before dates and farm or producer IDs directly on the shell, alongside logos or a traceability QR if required. Operators set the message on the touch screen, so each batch carries the right date and source identification automatically. That removes handwriting and manual stickers &#8211; common sources of mislabeled batches. 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&#215;6 tray (30 eggs) per cycle. Food-grade ink is available in six colors &#8211; red, yellow, blue, green, black and white &#8211; and dries without breaking shells. Linking the coder to the packing line turns coding from a manual step into...

Question 11

Is egg coding required for food safety compliance?

Accepted Answer

Egg coding is not always legally mandated everywhere, but dates, farm IDs and traceability codes are increasingly required or expected by retailers and food-safety schemes for recall management. A SHICAI egg coder lets you meet those requirements &#8211; and voluntary traceability is a strong selling point to buyers. Where a scheme does mandate shell coding, having the line ready avoids a costly last-minute retrofit. Food-grade ink is available in six colors &#8211; red, yellow, blue, green, black and white &#8211; and dries without breaking shells. Throughput is about 30 eggs in 11 seconds on an automatic line that also works on chicken, duck and preserved (pidan) eggs. Linking the coder to the packing line turns coding from a manual step...

Question 12

Can an egg coding machine print on stained eggs?

Accepted Answer

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...
