Small Scale Egg Grading and Washing Machine for Sale

This machine combines washing, gentle sanitizing, and size/weight grading in a single compact line suited for farms or packing houses processing up to 5,000 eggs per hour. It replaces separate manual washing stations and grading tables, reducing labor steps and minimizing egg handling damage.

Technical Specifications

Key Features

• Adjustable spray nozzles with variable pressure for effective dirt removal without shell micro‑cracking.
• Soft‑touch conveyor belts made of FDA‑approved polyurethane to prevent egg abrasion.
• Interchangeable grading trays that sort by weight (±2 g) or diameter (±1 mm) with quick‑change fixtures.
• Low‑volume water recirculation system with filtration to reduce consumption by up to 40 % compared with single‑pass washing.
• Integrated CIP (clean‑in‑place) circuit allowing automated sanitation cycles between batches.
• Emergency stop and overload protection compliant with CE machinery directive.

Applications

Small‑scale egg producers often face a trade‑off between labor‑intensive manual washing and the capital cost of large industrial lines. This machine fits mid‑size operations (500–2,000 hens) where consistent shell cleanliness and uniform grading are required to meet retail or food‑service specifications, while keeping floor space under 2 m² and allowing relocation for seasonal production changes.

Materials and Build Quality

All product‑contact surfaces are formed from AISI 304 stainless steel with 2B finish, providing corrosion resistance to mild alkaline detergents and facilitating easy wipe‑down. Seals and gaskets are made of food‑grade EPDM, rated for temperatures up to 80 °C and repeated CIP cycles. The frame uses welded square tubing with gusseted joints to absorb vibration from the conveyor drive, ensuring alignment of grading mechanisms over extended run times.

Customization Options

• Alternative grading criteria: shell strength measurement via non‑destructive acoustic resonance.
• Add‑on UV‑C sanitizer module for microbial reduction post‑wash.
• Extended conveyor length to interface directly with downstream packaging or carton‑forming equipment.
• Alternative motor voltages (230 V/400 V, 50/60 Hz) for regional power standards.
• Custom control software integration with existing MES via Modbus TCP or OPC UA.

Frequently Asked Questions

Can the machine be installed in an existing processing room with limited ceiling height?

The standard height is 1500 mm; a low‑profile version reduces overall height to 1300 mm by using a compact drive module, subject to a slight reduction in conveyor inclination angle.

What information is needed to prepare a formal quotation?

Required details include target hourly egg count, preferred grading parameter (weight, size, or both), water supply pressure and quality, available electrical supply, and any desired optional modules such as UV sanitizer or data‑logging interface.

How is the machine protected during overseas shipment?

The unit is disassembled into three sub‑assemblies (frame, conveyor/grading module, washing manifold), each wrapped in VCI‑treated film, placed in a wooden crate with corner bracing, and sealed with moisture‑barrier lining to meet ISPM‑15 standards for international transport.
