Factory Supply Compact Egg Grader For Small Farms
Factory Supply Compact Egg Grader for Small Farms
Compact egg graders address the need for consistent sizing on small‑scale operations where manual sorting is labor‑intensive and variable.
The machine uses a series of adjustable rollers with precisely spaced gaps to separate eggs into weight categories as they pass through.
Throughput depends on egg size and operator speed, typically ranging from 150 to 300 eggs per hour on a bench‑top unit.
Technical Specifications
| Parameter | Typical Value |
|---|---|
| Overall Dimensions (L×W×H) | 620 mm × 380 mm × 420 mm |
| Roller Gap Range | 30 mm – 55 mm (adjustable in 2 mm increments) |
| Motor Power | 0.18 kW, single‑phase, 220 V |
| Net Weight | 28 kg |
| Material Contact Surfaces | Food‑grade stainless steel (AISI 304) |
Construction Materials
The frame is fabricated from cold‑rolled steel with a powder‑coated finish to resist corrosion in humid barn environments.
All surfaces that contact eggs are made of AISI 304 stainless steel, which is non‑reactive and easy to clean.
- Rollers: hardened stainless steel with low‑friction polymer sleeves
- Guides and hoppers: food‑grade HDPE for impact resistance
- Fasteners: zinc‑plated steel with nylon lock nuts
Operating Principle
Eggs are fed manually into the inlet hopper where a gentle vibratory feeder aligns them in a single file.
As they travel downstream, each egg encounters a pair of rollers whose gap is set to a specific size threshold; eggs smaller than the gap pass through, while larger eggs are lifted and directed to the next lane.
The process repeats across four grading stages, yielding five output channels ranging from peewee to jumbo.
Applications for Small Farms
Small farms benefit from reduced sorting labor, allowing staff to focus on animal health and feed management.
Uniform egg sizing improves packaging efficiency and meets retailer specifications for grade A cartons.
The compact footprint fits on a standard workbench, eliminating the need for dedicated floor space.
Quality Control and Testing
Each unit undergoes a functional test where a calibrated set of eggs is run through the grader to verify lane accuracy within ±2 mm.
Material certification is verified for all stainless‑steel components, and surface finish is inspected for roughness below 0.8 µm Ra.
- Dimensional inspection of roller gaps using gauge blocks
- Run‑out measurement of rollers (<0.05 mm)
- Cleanability test following CIP protocol
Frequently Asked Questions
Can the roller gap be adjusted without tools?
Yes, each gap setting uses a thumb‑screw with a detent plate, allowing repeatable adjustments in 2 mm increments.
What information is required for a quotation?
