Industrial feed fish washing and sorting machine with extended conveyor design for aquaculture farms and feed processing plants. Integrates fish cleaning and manual sorting in one system. Factory-direct manufacturer offering commercial-grade, stainless steel equipment with customizable capacity and OEM solutions.
The HSYL Fish Washing & Sorting Machine is engineered for continuous seafood processing operations requiring stable throughput, consistent grading accuracy, and strict hygienic control. It integrates bubble washing, spray rinsing, and mechanical size grading into a compact stainless-steel structure suitable for fish processing plants, aquaculture facilities, and export-oriented seafood factories.
This system addresses two persistent production challenges: inefficient manual grading and inconsistent cleaning performance. By combining controlled water flow dynamics with calibrated sorting channels, the equipment reduces labor dependency while improving yield consistency and downstream packaging efficiency.
| Model | Capacity (kg/h) | Power (kW) | Dimensions (mm) | Material | Weight (kg) |
|---|---|---|---|---|---|
| HSYL-FWS-1000 | 500–1000 | 3.5 | 4200 × 1200 × 1500 | SUS304 | 850 |
| HSYL-FWS-2000 | 1000–2000 | 5.5 | 5200 × 1400 × 1600 | SUS304 | 1150 |
| HSYL-FWS-3000 | 2000–3000 | 7.5 | 6200 × 1600 × 1700 | SUS304 / SUS316 (optional) | 1500 |
Raw fish are fed into the infeed hopper and conveyed into the washing tank. The washing section utilizes a centrifugal water pump to generate controlled circulation. Air diffusers at the tank bottom create uniform bubble agitation, lifting debris and separating impurities from the fish surface.
After immersion washing, fish pass through a multi-stage spray rinsing zone equipped with stainless steel nozzles arranged at calibrated angles to ensure 360-degree coverage. Water flow rate and pressure are adjustable through stainless steel ball valves.
The grading section operates using a roller or bar-gap mechanical separation principle. As fish move forward, adjustable spacing gradually increases, allowing smaller fish to fall into designated collection channels. This passive mechanical grading ensures consistent size classification without electronic sensors, reducing maintenance complexity.
The drive system consists of a food-grade gearbox motor coupled with a chain-sprocket transmission assembly. All bearings are sealed and protected against water ingress. Electrical components are housed in an IP65 stainless steel control cabinet, equipped with PLC and HMI interface for speed control, emergency stop, and overload protection. The system complies with CE electrical safety standards and follows OSHA-aligned safety guarding principles.
In a standard 2000 kg/h seafood processing facility, the HSYL Fish Washing & Sorting Machine operates as the first critical control point after raw material reception. When handling chilled fish at 0–4°C, the machine maintains stable throughput without damaging skin integrity.
For small pelagic species such as sardine or anchovy, accurate size grading improves canning yield consistency. In whitefish processing plants, pre-sorting reduces fillet trimming loss by ensuring uniform raw material dimensions before mechanical filleting.
As part of a complete turnkey project, the equipment can be integrated with deheading, gutting, filleting, trimming, and automatic weighing systems. Water recycling modules and filtration tanks can be added to reduce overall water consumption, supporting sustainable seafood production practices.
HSYL designs and manufactures industrial food processing machinery under strict quality control protocols. Our equipment is built with traceable stainless steel materials and compliant with CE requirements. For export-oriented seafood factories targeting BRC-certified markets, hygienic design principles are incorporated from the structural framework to fastener selection.
We provide OEM and ODM customization based on fish species, plant layout, voltage standards (220V/380V/415V, 50/60Hz), and automation level. On-site installation and commissioning services are available, including operator training and performance validation.
Spare parts supply and remote technical support ensure minimal downtime. Detailed layout drawings, utility consumption data, and ROI analysis can be provided during project planning.
