Fish weight sorting machine type and core technology comparison

There are usually two kinds of fish sorting machines, one is belt type, and the other is tray type.

Type	Applicable scene	Technical advantage	Design challenge
Belt	• Large fish (tuna/skipjack) • High throughput production lines (60 PCS/min)	• High speed continuous sorting • Compatible with irregular object sorting	• Frozen fish anti-slip and anti-stick design • Belt wear resistance optimization
Tray	• Small and medium-sized high value added fish (Salmon/Cod) • Scenes that need to be accurately graded	• High precision weighing (±0.5g) • Independent sorting to prevent cross contamination	•Tray anti-stick coating technology • Synchronous control of high speed sorting robot arm

Key Technical Highlights of Our Customized Fish Processing Line

1. Fish-Friendly Design

Frozen Fish Line:
Uses a special anti-slip belt with teeth and air-powered pushers. This increases grip and control by 40%, even on slippery frozen fish.
Fresh Fish Line:
Equipped with self-cleaning nylon brushes and food-safe silicone scrapers. This setup removes up to 99% of surface mucus, keeping fish clean.
Open-Back Fish Line:
Built-in camera system checks for leftover guts. When found, it automatically activates high-pressure water jets for cleaning.

2. Smart Control System

Accurate Weighing:
Uses high-precision sensors and smart algorithms to weigh fish even when the machine is shaking.
Smarter Sorting:
The system learns from past data and adjusts automatically, improving sorting accuracy and increasing yield by 15–20%.
Remote Monitoring:
Managers can check machine performance and get early alerts for maintenance — all in real time via the internet.

Future Technology Goals

1. Cold Environment Sorting:

Working on a system that can sort fish directly in freezing conditions (-18°C), avoiding the need to defrost and refreeze — which saves energy and time.

2. AI-Powered Quality Checks:

Planning to replace manual inspection with 3D cameras and AI to check fish quality, color, and appearance.

3. Flexible Robot Packing:

Developing robot systems that can adjust to different packing styles (boxes, trays, vacuum bags) and work safely alongside people.
