CB Yellow Croaker Aquaculture Farming Vessel Processing System
CB，as a technology integrator for aquaculture vessel processing system, CB combines expert knowledge of yellow croaker processing with onboard process conditions to design dedicated marine processing system.
Yellow croakers are extremely prone to mechanical injuries and freshness loss once out of water, with scale and mucus shedding as well as surface congestion especially in the tight space and rolling conditions of processing vessel. CB provides the solutions that precisely match ship-owners operational needs.
Tailored to vessel types, sea states, and transport distances,
-
Gentle Processing Mode
Slurry ice chilling induces rapid dormancy to minimize fish stress and physical friction, effectively preventing scale loss during processing.
-
Onboard Automated Process Line
The fully automated system suitable to marine environment maintains stable production speed, replacing repetitive manual operation and eliminating the need for large crews at sea.
-
Full Chain Freshness Preservation
From harvesting and dormancy to grading, preservation, and packaging, catches are treated with slurry ice throughout to maintain a controlled, low-temperature environment.
Main Process for Yellow Croaker
● Pump Harvesting ● Live Fish Dormancy ● Slurry Ice Chilling ● Quick Freezing ● Weight Grading ● Vacuum Packaging ● Boxing & Labeling ● Slurry Ice Preservation ● Box Sealing ● Strapping ● Metal Detection ● Automatic Palletizing ● Cold Storage
Gentle Transfer Minimizes Mechanical Damage to Fish
The fragile scales and mucus layer of yellow croakers make them highly susceptible to scraping, congestion, and scale loss during traditional net transfers, directly resulting in massive catch losses.
CB low-pressure fluid channel conveying ensures fluid-enveloped transport throughout harvesting, dewatering, and dormancy tank entry, minimizing hard contact and surface injury to fish. The flow tunnels are optimized according to farming vessel condition, significantly reducing stress and abrasion. The solution is flexibly adaptable to all production scenarios with high-batch raw material transferring, avoiding degrading losses from source.
Controlled Low-Temperature Slurry Ice Dormancy Preserves Natural Golden Appearance
Stress of yellow croakers inhibits the deposition of golden pigments on fish body, leading to dull color and significant drop in commercial value.
CB utilizes slurry ice to have an exclusive low-temperature hypoxia dormancy process. After pumping-suction and de-water, yellow croakers enter into dormancy tank, rapidly creating a low-metabolic environment locking in vibrant golden pigmentation. Slurry ice gently envelops the fish throughout to protect scales and surface mucus, preserving their natural golden appearance and ensuring a uniform, premium finish for fresh or frozen products that significantly boosts market value and competitiveness.
Full-Chain Slurry Ice Preservation, Extends Shelf Life
Slurry ice is the ultimate medium for locking in peak freshness the moment fish leave the water. CB Slurry Ice System features with dual-mode concentration control, providing complete temperature management across the entire chilling and transport lifecycle:
30% Slurry Ice Concentration: Offers exceptional fluid dynamics, fully enveloping processed fish body for ultra-fast deep-chilling, instantly bringing catches to optimal fresh condition.
50%–70% Slurry Ice Concentration: Ideal for crate packing, extended cold storage, and long-haul transportation of fresh-chilled fish.
Integrated Dual-Mode Switching: CB Slurry Ice control system dynamically regulates and switches between both concentration modes on demand. Significantly saves onboard space and reducing energy consumption.
On-Board Automated Production Line Adapted to Marine Condition
Considering tight onboard space, continuous hull rolling, operation difficulty on marine, manual grading errors, and high labor costs, CB integrates automated weighing and grading, continuous tunnel freezing, vacuum packaging & labeling, and automatic palletizing modules to replace repetitive manual labor.Automated grading eliminates size discrepancies caused by human fatigue, standardizes finished product specifications, and reduces sorting losses. Through full-line automated operation the system matches stable production speed and eliminates the need for large operators on vessel.
Slurry Ice Preservation - Ensures Long-Term Storage & Transportation Quality
Automated connection from production output to cargo hold. Instead using angular crushed ice, it uses rounded, high-concentration slurry ice for complete enveloping preservation, ensuring even cooling without surface scratches and sustained low-temperature release to delay freshness decay. Finished tubs are neatly stacked to maximize cargo hold space utilization, establishing a fully automated workflow from harvesting / processing to cargo hold / external transporting ensuring controlled product quality of logistics process.
