China Egg Washer Grader Machine For Sale

China Egg Washer Grader Machine for Sale

The egg washer grader integrates cleaning, rinsing, and size/weight classification into a single continuous line. It is designed for hatcheries, commercial egg processing plants, and food‑service facilities that require consistent microbial reduction and uniform product flow.

Typical units handle 5,000 to 30,000 eggs per hour depending on model selection, with adjustable wash pressure, temperature control, and programmable grading thresholds to match specific customer specifications.

Working Principle

Eggs are fed onto a gently vibrating conveyor that transports them through a pre‑wash spray zone where loose debris is removed. They then enter a rotating brush chamber with adjustable pressure nozzles that scrub the shell surface using food‑grade detergent solution at controlled temperature. After brushing, a high‑pressure rinse removes residual chemicals, followed by an air‑knife drying stage that reduces surface moisture to less than 0.5 % weight. Finally, each egg passes over a load‑cell weighing station and an optical size sensor; based on user‑defined thresholds, the conveyor diverts eggs into one of three graded outlets.

Applications

The machine reduces labor‑intensive manual washing and eliminates variability in egg quality that can affect hatchability or downstream product safety. By delivering a consistent microbial load and uniform size distribution, it supports higher hatch rates in breeding operations and meets strict retail grading standards for table eggs.

Commercial layer farms producing table eggs for supermarkets
Hatcheries requiring sanitized, uniform eggs for incubation
Egg‑product manufacturers needing clean input for liquid or powder processing

Key Features

Adjustable wash pressure (0.2–0.8 MPa) and temperature (30–60 °C)
Food‑grade 304 stainless steel construction with sanitary welds
IP65 rated electrical enclosure for dust and water resistance
Programmable logic controller with touch‑screen HMI for recipe storage
Low‑water‑consumption recycle system (≤ 15 L/h fresh water)

Quality Assurance

Each unit undergoes hydrostatic testing of the wash tanks at 1.5× operating pressure, dye‑penetrant inspection of critical welds, and functional verification of all sensors under load. The control software is validated against IEC 61508 safety integrity level 1 requirements, and the machine complies with CE marking directives for machinery and food‑contact equipment.

Customization Options

Throughput scaling from 5,000 to 50,000 eggs/hour via modular conveyor sections
Alternative heating methods: electric, steam, or hot‑water circulation
Choice of stainless steel grades (304, 316L) for corrosive environments
Integration with existing packing lines through custom inlet/outlet adapters
Optional UV‑C post‑rinse sterilization for additional microbial reduction

FAQ

Can the machine be adapted for different egg sizes?

Yes, the grading thresholds are user‑adjustable via the HMI, allowing accommodation of small, medium, large, or jumbo eggs without mechanical changes.

What information is required for a quotation?

Required data include desired eggs‑per‑hour capacity, electrical supply voltage, preferred construction material, and any special options such as UV sterilization or custom inlet/outlet dimensions.

How is the machine protected during overseas shipment?

Units are packed in heat‑treated wooden pallets with corrosion‑inhibiting film, shock‑absorbing foam corners, and sealed with desiccant packs to prevent moisture ingress.
