Surimi Processing Automatic Production Line

High-Efficiency Fish Paste Production Solution for Industrial Plants

The Surimi Processing Automatic Production Line is designed for large-scale seafood processors aiming to produce high-quality fish paste (surimi) with stable gel strength, uniform texture, and high yield. The line integrates washing, deboning, refining, dewatering, mixing, and forming processes, delivering a fully automated, hygienic, and export-oriented surimi production solution.

1. Application Overview

This production line is widely used for processing:

• Frozen or fresh fish into surimi

• White fish species (Alaska pollock, threadfin bream, croaker, pangasius, tilapia, etc.)

• Raw material for:

  • Crab sticks

  • Fish balls

  • Fish cakes

  • Fish sausages

  • Seafood analog products

2. Designed Capacity & Performance

• Capacity Range: 5 – 300 tons/day (customizable)

• Hourly Throughput: 1 – 15 tons/hour

• Operating Mode: Continuous automatic processing

• Raw Material: Whole fish / fish trimmings

The system supports modular expansion and multi-line parallel operation for industrial-scale production.

3. Complete Process Flow

Raw Fish Feeding → Crushing → Washing → Meat Separation → Refining → Dewatering → Mixing & Cryoprotectant Addition → Forming / Packing → Freezing or Further Processing

4. Key Processing Sections & Equipment

4.1 Raw Material Feeding & Crushing

• Automatic hopper feeding system

• Fish crusher / mincer

• Uniform particle size for stable downstream processing

Ensures continuous and controlled raw material input.

4.2 Multi-Stage Washing System

• Drum or screw-type washing machines

• Multiple washing cycles to remove blood, fat, and impurities

• Adjustable water flow and washing time

Result: Improved whiteness and gel strength of surimi.

4.3 Meat Separation & Deboning

• High-efficiency fish meat separator

• Precise separation of meat from skin, bones, and scales

• Stable output with minimal protein damage

4.4 Refining System

• Fine refiner screens (customizable mesh size)

• Removes remaining impurities and connective tissue

• Improves texture smoothness and consistency

4.5 Dewatering System
