1. Introduction to Egg Sorting Line
An Egg Sorting Line is an integrated, automated system designed to handle, sort, grade, and prepare eggs for packaging on a large scale. This line combines multiple components such as egg conveyors, graders, washers, candlers, and packers to streamline the egg processing workflow. With the growing demand for efficient poultry production and high-quality eggs, egg sorting lines have become essential in commercial farms, packing plants, and distribution centers.
Egg sorting lines optimize the process by automating egg grading based on size, weight, and quality attributes, reducing manual labor, minimizing breakage, and ensuring consistency. Advanced models incorporate real-time data monitoring and integration with smart farm systems for precision and traceability.
This article presents an in-depth guide on egg sorting lines, including technical parameters, key features, advantages, application scenarios, operating instructions, maintenance tips, and frequently asked questions to aid producers and processors in understanding and utilizing this critical technology.

An egg sorting line typically consists of several integrated components working in synchronization:
Egg conveyors gently transport eggs from collection points to grading machines. Designed to minimize impact, these conveyors are made from soft rollers, belts, or cushioned tracks.
Equipped with high-precision weight sensors and size detectors, graders classify eggs into various categories automatically based on predefined standards.
Some lines incorporate washers that clean eggs before sorting, ensuring better hygiene and quality compliance.
Candling stations use light to detect internal defects, cracks, or abnormalities in eggs to enhance quality control.
Sorted eggs are transferred directly to automatic packing machines, which arrange eggs into trays or cartons for distribution.
A centralized PLC system with touchscreen interface enables easy operation, real-time monitoring, parameter adjustment, and data collection.
Capable of processing tens of thousands to over 100,000 eggs per hour, enabling large-scale commercial production.
Advanced sensors ensure sorting accuracy above 98%, improving product consistency and market compliance.
Conveyors and rollers are designed to minimize egg breakage during transport and processing.
Lines can be customized and expanded to fit specific production needs and integrate with existing farm infrastructure.
Constructed from stainless steel and food-safe materials, allowing easy cleaning and compliance with food safety standards.
Integrated software allows for collection and analysis of production data, supporting traceability and operational optimization.
Automation reduces manual labor requirements and speeds up the entire egg processing workflow.
Integration of grading, washing, and candling ensures only high-quality eggs proceed to packing.
Careful design and automation minimize breakage and product loss.
Uniform grading improves marketability and consumer satisfaction.
Integrated components reduce bottlenecks, allowing continuous production and easy scale-up.
Large poultry farms use egg sorting lines to process and prepare eggs efficiently for market.
Packing plants employ sorting lines to streamline grading and packing operations.
Centers sorting bulk eggs use these lines to prepare products for retail and food service industries.
Firms processing eggs into liquid, powder, or other forms rely on sorting lines to ensure quality input materials.
Ensure power supply is stable and grounded.
Check all mechanical parts for proper installation.
Calibrate grading sensors and check conveyors.
Set sorting parameters on the control panel.
Start the conveyor system and load eggs onto the feeding conveyor.
Monitor grading and sorting via the control interface.
Collect sorted eggs at designated outlets.
If applicable, operate washers and candlers as needed.
Oversee packing operations downstream.
Gradually reduce conveyor speed and stop egg feeding.
Power down grading, washing, and packing machines.
Perform cleaning as per schedule.
Clean conveyor belts, rollers, and sensors.
Remove eggshell debris and dust.
Check for abnormal noises or vibrations.
Lubricate moving parts.
Inspect belts, rollers, and sensors for wear.
Calibrate sensors as necessary.
Thoroughly inspect mechanical and electrical components.
Replace worn or damaged parts.
Update software and firmware if applicable.
Line not starting | Power issue or emergency stop | Check power, reset emergency stop button |
