We are thrilled to share a behind-the-scenes look at one of our latest installations: the RNJet 100 industrial inkjet printer, now integrated with Yamasa Egg Graders for precise BestBefore date and LOT marking on egg cartons.
In today’s competitive egg production and packaging industry, accuracy, traceability, and efficiency are more critical than ever. From maintaining compliance with food safety regulations to ensuring consumers receive fresh, high-quality eggs, proper marking and coding on egg cartons is an essential part of modern egg processing lines.
Food safety compliance: Proper BestBefore dates ensure consumers know exactly how fresh the eggs are.
Traceability: LOT numbers allow producers and distributors to track batches in case of quality issues or recalls.
Professional packaging: Clean, consistent markings improve brand perception and shelf appeal.
Operational efficiency: Automated coding reduces human error and speeds up production lines.
Manual marking or outdated printers can slow down operations, smudge the print, or even miss cartons – which is costly for large-scale egg producers. That’s where RNJet 100 comes in.
High-resolution printing: Crisp, legible BestBefore dates, LOT numbers, and batch codes.
Non-contact inkjet technology: Prints directly on cartons without smudging or damaging the surface.
Fast operation: Keeps up with high-speed egg grading and packing lines.
Easy integration: Seamlessly installs on existing equipment like Yamasa Egg Graders.
User-friendly interface: Operators can change print content quickly without downtime.
Durable design: Built to withstand industrial environments while minimizing maintenance.
With the RNJet 100, egg producers can achieve consistent, error-free marking that keeps every carton compliant and professional.
Yamasa Egg Graders are renowned for:
Precision grading: Sorting eggs by size and weight with exceptional accuracy.
High throughput: Handling thousands of eggs per hour without compromising quality.
Reliable automation: Reducing manual labor while maintaining consistent quality.
By combining RNJet 100 coding technology with Yamasa Egg Graders, egg producers now have a fully automated solution where grading and marking happen in perfect harmony.
We recently installed the RNJet 100 on a customer line equipped with Yamasa Egg Graders. Here’s what makes this setup special:
Custom integration: The RNJet 100 was configured to match the speed and layout of the Yamasa grading line.
Optimized printing height and angle: Ensuring every egg carton receives a crisp BestBefore and LOT code.
Operator training: Our team provided hands-on training so the staff could adjust codes, change ink, and monitor performance effortlessly.
