B2B Egg Grading Machine Sorting Eggs By Size
B2B Egg Grading Machine – Sorting Eggs by Size
The machine receives mixed‑size eggs from a conveyor and separates them into discrete size categories based on precise diameter measurements. Each egg is guided to a dedicated lane where it is gently deposited into the appropriate collection bin.
Sorting occurs at rates up to 30,000 eggs per hour with a size‑classification tolerance of ±0.5 mm, ensuring that downstream packaging lines receive uniform batches that meet retail specifications.
Operating Principle
Eggs travel on a low‑vibration belt onto a rotating drum equipped with laser‑based diameter sensors. The sensor data triggers pneumatic diverters that shift each egg onto one of several concentric tracks corresponding to preset size ranges.
Gentle rubber‑coated guides prevent cracking, while a synchronized timing mechanism maintains consistent spacing between eggs, minimizing jamming and maximizing throughput.

Key Features
- Laser diameter measurement with repeatability better than 0.1 mm.
- Stainless‑steel (AISI 304) contact surfaces for corrosion resistance and easy cleaning.
- Adjustable size thresholds via HMI; no mechanical changeover required.
- Low‑noise operation (<68 dB) suitable for indoor processing environments.
- Integrated reject chute for misshapen or contaminated eggs.
Applications in Poultry Processing
Uniform egg size is critical for automated carton filling, where mismatched dimensions cause line stoppages and increase labor for manual re‑sorting. By delivering tightly graded batches, the machine reduces carton‑sealing failures and improves overall packaging line efficiency.
In addition, consistent size enables precise weight‑based pricing and compliance with retail specifications that limit size variation to within a defined grade, thereby supporting traceability and quality‑assurance programs.
Customization Options
- Alternative sensor technologies (vision‑based or ultrasonic) for specific lighting conditions.
- Variable lane configurations from 3 to 7 size classes.
- Explosion‑proof motor kits for facilities handling combustible dust.
- Custom infeed and outfeed conveyor lengths to match existing line layouts.
- Optional CIP (clean‑in‑place) spray nozzles integrated into the frame.
Quality Assurance
Each unit undergoes a factory acceptance test that verifies measurement accuracy across the full size range using calibrated gauge eggs. The test includes a 24‑hour endurance run at rated capacity to confirm thermal stability of the laser sensors and mechanical wear of the diverters.
Material traceability is maintained for all stainless‑steel components, and surface finishes are inspected for roughness values below 0.8 µm to ensure effective cleaning and resistance to bacterial adhesion.
Frequently Asked Questions
A: Yes, thresholds are modified via the HMI and take effect on the next egg cycle; no mechanical changeover is required.
A: Required details include target hourly capacity, desired number of size classes, inlet/outlet conveyor specifications, and any environmental constraints (e.g., wash‑down rating, explosion‑proof needs).
A: Standard frames are constructed from powder‑coated carbon steel; optional upgrades to AISI 316 stainless steel are available for corrosive environments.
