Layers (packing) · 120,000 eggs/hour
Egg grading & packing center — Jordan
Illustrative scenario: central grading and packing facility receiving eggs from 3 upstream layer farms. Sourcing covered in-line grader, printer, packer, egg washer/dryer and cold room.
Load requirements
Design loads used to size housing, utilities and equipment.
Grading throughput
120,000 eggs/h (2 lanes × 60k)
Peak electrical load
180 kW
Wash water demand
3 m³/h with reclaim
Cold room capacity
1.5 M eggs @ 13 °C / 75% RH
Compressed air
800 L/min at 7 bar
Truck bay throughput
6 trucks/day inbound + 4 outbound
System design choices
Why each subsystem was specified the way it was.
| Area | Choice | Rationale |
|---|---|---|
| Grader | Twin-lane in-line with vision + acoustic crack | Vision handles dirt/blood spots; acoustic catches hairline cracks vision misses (~2%). |
| Wash/dry | 3-stage wash (50/45/40 °C) + hot-air dry | Meets export shell-egg wash spec while limiting cuticle damage. |
| Packing | Robotic case packer, 30-cell tray + 6×5 case | Removes bottleneck at end-of-line and reduces breakage during transfer. |
| Cold storage | Two-zone 13 °C / 7 °C rooms + humidity | 13 °C for outbound shell egg; 7 °C for liquid egg buffer prior to pasteurizer. |
| Traceability | In-line laser printer with lot + farm ID | Retailer traceability requires per-egg farm code, lay date and best-before. |
