A fishmeal production line is a crucial facility for processing fish or fish by-products into high-protein fishmeal, and the fish cooking machine is one of the core equipment in the entire production process. This article will detail the function, working principle, and value of Shuliy fish cooker in a fishmeal production line.

What is a fish cooking machine?
Fish cooking equipment is specifically designed for high-temperature cooking of fish raw materials. Its main function is to cook fish or fish waste, causing the fish protein to coagulate and the fat to separate, thereby preparing it for subsequent processing, including pressing, degreasing, drying, and pulverizing.
In Shuliy’s fishmeal production line, the fish cooker employs a jacketed heating and shaft-filled steam design to ensure uniform heat distribution, improving production efficiency and the quality of the finished fishmeal.
Role of the fish cooker in Shuliy fish meal production line
- Improved protein retention rate
- The cooking process effectively prevents protein loss, resulting in higher protein content in fishmeal, suitable for animal feed.
- Oil removal and separation
- Cooking softens the fish tissue, facilitating the separation of fish oil and residue in the subsequent pressing. The fish oil can be further processed, increasing added value.
- Disinfection and detoxification
- High-temperature cooking kills bacteria and pathogens, ensuring fishmeal production meets food safety and environmental protection requirements.
How does the fish cooker machine work?
Shuliy fish cooking machine completes processing through the following steps:
- Feeding: Fish waste enters the cooking machine through the feed inlet.
- Heating steam: High-temperature steam is injected into the jacket, and steam is simultaneously added to the shaft, ensuring uniform heating.
- Cooking process: The fish undergoes coagulation, softening, and oil removal under high temperature and pressure.
- Discharging: The cooked fish is pushed to the press or the next process.
This design not only improves thermal efficiency but also reduces energy consumption and shortens the production cycle.

Why choose Shuliy fish cooking machine?
Fish cooking machines are indispensable equipment in fishmeal production lines. Choosing a Shuliy fishmeal production line means:
- Utilizing efficient and energy-saving cooking technology
- Ensuring fishmeal protein content and finished product quality
- Enhancing the added value of fishmeal and fish oil
- Obtaining comprehensive pre-sales consultation and after-sales service
Whether it’s a small or medium-sized fishmeal plant or a large seafood processing enterprise, Shuliy fish cooking machines can provide stable and efficient production guarantees.
