Egg Tray Washer for Egg Processing Plants

Overview

The egg tray washer is designed to clean, sanitize, and dry reusable trays used in high‑volume egg processing lines. It removes organic residue, shell fragments, and microbial contaminants while preserving tray integrity for multiple reuse cycles.

Working Principle

Trays enter the machine on a stainless‑steel conveyor and pass through a series of spray zones. High‑pressure nozzles deliver heated water mixed with approved detergent, followed by a rinse stage with filtered water. A final air‑knife or heated blow‑off removes excess moisture before trays exit the system.

• Pre‑wash spray loosens adhered debris.
• Main wash uses 60‑80 °C water with controlled detergent concentration.
• Rinse stage removes chemical residue.
• Drying zone employs heated air or centrifugal blowers to achieve < 5 % surface moisture.

Key Technical Specifications

Applications in Egg Processing

In modern egg plants, trays are reused dozens of times to reduce packaging waste and cost. The washer meets the stringent hygiene requirements of FDA 21 CFR 117 and EU EC 852/2004 by delivering a validated log‑reduction of surface microorganisms. Its enclosed spray design prevents cross‑contamination between clean and soiled trays, supporting continuous line operation without manual handling.

Customization Options

• Tray width and length adapters (standard 30 × 40 cm to 45 × 60 cm)
• Adjustable wash cycle time (30 s – 180 s)
• Water temperature control range (40 °C – 90 °C)
• Detergent dosing pump with flow‑rate feedback
• Material upgrade to AISI 316L for corrosive environments
• Optional hot‑air drying module or infrared drying zone

Quality Control and Materials

All structural components are fabricated from certified stainless steel sheets, with TIG welding performed according to ASME Section IX. Post‑fabrication, surfaces undergo pickling and passivation to ensure a passive chromium‑oxide layer. Gaskets and seals use FDA‑approved EPDM or silicone, tested for compression set < 15 % after 500 h at 80 °C. Each unit receives a hydrostatic pressure test at 1.5× design pressure and a functional test covering spray pressure, temperature stability, and conveyor speed accuracy.

Frequently Asked Questions

• Can the tray dimensions be customized? Yes, adjustable guides and interchangeable trays accommodate widths from 250 mm to 500 mm and lengths from 300 mm to 600 mm.
• What information is required for a quotation? Required data include tray size, desired throughput, water temperature preference, available utilities (voltage, water pressure), and any special material or certification needs.
• Which materials are available for the wash chamber? Standard is AISI 304 SS; AISI 316L SS is offered for higher chloride resistance. Food‑grade polymers are used for non‑structural covers.
• How is quality inspected before shipment? Each unit undergoes dimensional verification, leak testing, electrical safety (HI‑POT), and a performance run with a sample load of trays.
• What is the typical production lead time? Standard configurations ship within 6–8 weeks after receipt of purchase order; customized units may require 10–12 weeks.
