B2B Large Capacity Scale Egg Grader Machine
B2B Large Capacity Scale Egg Grader Machine
This equipment sorts eggs by weight and size using a combination of load‑cell weighing stations and optical sizing sensors arranged on a continuous conveyor. The system is designed for high‑volume processing lines where consistent grading directly impacts downstream packaging and product value.
Grading Principle
Each egg passes over a series of individual weighing cells that capture its mass with a resolution of 0.1 g. Simultaneously, a laser‑based diameter sensor measures the egg’s equatorial width. The controller compares the measured values against user‑defined grade thresholds and activates pneumatic diverters to route the egg into the appropriate collection lane.

Construction Materials
The frame is fabricated from cold‑rolled steel with a powder‑coated finish for corrosion resistance. Contact surfaces that interact with eggs are made of food‑grade stainless steel (AISI 304) and FDA‑approved polymer belts. All moving bearings are sealed, lubricated‑for‑life units to minimize maintenance intervals.
Industrial Applications
- Large‑scale egg packing plants requiring uniform weight grades for retail cartons.
- Breeding facilities that sort eggs for incubation based on size and weight uniformity.
- Processing lines producing liquid egg products where consistent feedstock weight improves yield.
Customization Options
Customers can specify the number of grading lanes (from 2 to 8) to match plant layout. The control software allows storage of up to 20 programmable grade profiles, each with independent weight and size thresholds. Optional features include a reject‑egg counting module, integrated data logging for traceability, and a wash‑down rated enclosure for high‑humidity environments.
Quality Control Process
Before shipment, each machine undergoes a functional test using calibrated test masses ranging from 20 g to 100 g to verify weighing accuracy across the full range. Optical sensors are checked with certified gauge blocks to confirm size measurement repeatability. All pneumatic diverters are cycled 5,000 times to ensure reliable operation under continuous load.
Frequently Asked Questions
- Can the lane spacing be adjusted for different egg sizes? Yes, the lateral guides on each lane are sliding and can be set between 30 mm and 70 mm to accommodate varied egg diameters.
- What information is needed for a quotation? Required details include target throughput, desired number of grades, any specific rejection handling, and site power specifications.
- How is the machine protected during overseas shipment? The unit is secured on a steel pallet, wrapped in vapor‑ barrier film, and placed inside a wooden crate with corner bracing to withstand standard container handling.
