Used Egomatic Egg Grading Equipment for Sale in Australia

Overview

Egomatic egg graders are continuous‑flow machines that sort eggs by weight and size using precision load cells and mechanical diverting gates. Typical models process between 15,000 and 30,000 eggs per hour across 4 to 8 lanes, with weight grading accuracy maintained within ±2 g and size grading steps of 2 mm. The frame and contact surfaces are constructed from AISI 304 stainless steel to resist corrosion from egg wash and cleaning chemicals.

Technical Specifications

Key Engineering Features

• Load‑cell based weight sensors calibrated to ±0.5 % full scale, enabling repeatable grading across shifts.
• Mechanical diverting gates actuated by pneumatic cylinders with response time < 150 ms, minimizing egg damage during sorting.
• Modular lane design allows individual lane isolation for maintenance without stopping the entire line.
• Open‑frame construction provides clear access to belts, rollers, and sensor arrays for cleaning and inspection.
• Variable frequency drives (VFDs) on main conveyors enable speed adjustment from 0.5 m/s to 2.0 m/s to match upstream packing rates.

Applications in the Poultry Processing Industry

Egg graders are positioned after washing and drying stations to separate product into market‑specific categories such as retail, breaking, and liquid egg streams. Accurate weight grading reduces giveaway in retail packs by ensuring each carton meets the declared net weight, while size grading optimizes carton fill rates and reduces packaging material usage. The ability to divert off‑spec eggs to a breaking line increases overall yield and supports traceability requirements of modern food safety standards.

Considerations When Buying Used Equipment

When evaluating a used Egomatic grader, verify the calibration history of the load‑cell arrays; drift beyond ±0.5 % indicates need for recalibration or sensor replacement. Inspect the pneumatic gate actuators for seal wear, as leaking air pressure reduces sorting speed and can cause egg breakage. Review the wear on stainless‑steel belts and rollers; surface pitting exceeding 0.2 mm depth may affect product flow and increase cleaning time. Confirm that the control panel includes functional emergency stops and that any outdated PLC modules have available spare parts or upgrade paths.

Inspection & Refurbishment Process

A typical refurbishment includes: disassembly of all contact surfaces, chemical cleaning with food‑grade alkaline solution, magnetic particle inspection of load‑cell mounting brackets, replacement of worn belts with FDA‑approved polyurethane belts, re‑grooving of diverting gate shafts, and reinstallation of pneumatic cylinders with new seals. After reassembly, the machine undergoes a performance test using a calibrated egg sampler to validate weight grading accuracy within ±2 g across the full operating speed range.

Warranty & Support

Suppliers of used grading equipment commonly offer a limited warranty covering major subsystems (load‑cell array, pneumatic gate system, drive motors) for 90 days from installation, contingent on proper installation and preventive maintenance. Technical support is available via remote diagnostics for PLC‑based units and on‑site service for mechanical adjustments. Spare parts such as load cells, belts, and pneumatic seals are typically held in regional stock to minimize downtime.

Frequently Asked Questions

• Can the lane count be changed after purchase? Yes, the modular frame allows addition or removal of lane kits; however, the drive motor and controller must be rated for the new total load.
• What information is needed for a quotation? Provide the target eggs‑per‑hour, required weight and size grades, available electrical supply (voltage, phase), and any space constraints for installation.
• Are food‑grade lubricants included? Refurbished units are lubricated with NSF H1‑approved grease on all bearings and gearboxes.
• How is the equipment shipped to Australia? Machines are disassembled into skid‑mounted sections, wrapped in vapor‑barrier film, and secured in a 20‑ft container with shock‑absorbing pallets.
