Oyster Cleaning and Grading Integrated Solution
The Oyster Cleaning and Grading Integrated Solution is a fully automated, high-efficiency processing system tailored for commercial oyster farming, seafood processing plants, and aquatic product enterprises. Integrating intelligent cleaning, impurity removal, surface polishing, size classification, weight sorting, and automatic conveying functions into one streamlined workflow, this solution solves the pain points of traditional oyster processing such as low manual efficiency, inconsistent cleaning quality, inaccurate grading, and high labor costs. Designed for the marine aquaculture industry’s stringent hygiene and production standards, the system realizes full-process automated processing from raw oyster feeding to finished product sorting, greatly improving production capacity and product uniformity while ensuring food safety and compliance with international seafood processing regulations.
This solution integrates multiple independent processing procedures including high-pressure water cleaning, brush scrubbing, mud and shell residue removal, surface disinfection, size screening, and weight grading into a single compact production line. It eliminates the need for separate equipment configuration and manual transfer between processes, simplifying the production layout, reducing workshop space occupation, and realizing one-stop processing of raw oysters to qualified finished products.
Equipped with circulating high-pressure water jet systems and flexible soft brush groups, the equipment thoroughly removes surface sediment, algae, barnacles, and residual impurities on oyster shells without damaging the oyster shell integrity and internal meat quality. The circulating water filtration and recycling system effectively reduces water consumption, achieving environmental protection and energy-saving production while maintaining continuous and stable cleaning effect.
Adopting advanced photoelectric sensing and intelligent weight detection technology, the system supports multi-standard grading based on oyster shell length, width, thickness, and single weight. It can customize grading standards and divide oysters into multiple specifications such as extra-large, large, medium, small, and mini. The intelligent identification system ensures a grading accuracy rate of over 99%, avoiding specification confusion caused by manual visual judgment and improving the market competitiveness of finished products.
The whole processing process adopts simulated manual flexible operation. The adjustable conveying speed and soft contact structure avoid extrusion, collision, and damage to oysters during cleaning and sorting. Compared with traditional manual processing and rigid mechanical equipment, the product damage rate is reduced to less than 0.5%, effectively improving the finished product yield and economic benefits of enterprise processing.
The system is equipped with an intelligent touch control panel, with visualized operation interface and one-key start/stop function. It supports parameter adjustment of cleaning intensity, processing speed, and grading specifications according to different oyster varieties and production needs. The whole machine adopts food-grade stainless steel material, which is corrosion-resistant, easy to clean, and meets food hygiene standards. The modular design simplifies daily maintenance and parts replacement, reducing equipment operation and maintenance costs.
Step 1: Automatic Feeding – Raw oysters are evenly and quantitatively fed into the production line through the vibrating feeding device to avoid material accumulation and ensure continuous and orderly processing.
Step 2: Preliminary Impurity Removal – Large-particle sediment, floating algae and loose attachments on the oyster surface are removed through primary water flushing and vibration screening.
Step 3: Fine Cleaning & Polishing – High-pressure circulating water jets and rotating soft brushes perform all-round dead-angle-free cleaning on oyster shells to remove stubborn impurities, realizing shell surface cleaning and polishing.
Step 4: Surface Disinfection & Rinsing – Food-grade atomized disinfection and pure water rinsing are carried out to eliminate surface bacteria and residual dirt, meeting food safety production requirements.
Step 5: Intelligent Grading & Sorting – The photoelectric and weight sensing system automatically identifies oyster specifications, and the intelligent sorting mechanism accurately classifies oysters into corresponding material boxes according to preset standards.
Step 6: Finished Product Output – The graded finished oysters are automatically output and can be directly connected to packaging equipment to realize assembly line production.
