fish meal and oil PROCESSING

Modern fish meal and oil processing relies on continuous wet reduction technology to convert raw fish (whole fish/trimmings) into high-protein fish meal (65-72%) and premium fish oil rich in Omega-3.

Our turnkey plants achieve >99% yield efficiency with <15 ppm exhaust odor – meeting feed safety standards for global exporters.

How does fish meal and oil are produced

The fish meal plant production line typically includes equipment for cooking, pressing, and drying, as well as ancillary equipment for handling and processing the raw materials and finished products.

Preprocessing

To make drying easier, one can crush the larger fish, while smaller ones only need to steamed.

Cooking

Indirect steam cookers with ±1°C accuracy (80-95°C) to coagulate protein without overheating oil.

Pressing

Twin-screw presses achieve >85% liquor yield & <50% press cake moisture – critical for dryer efficiency.

Separation

3-phase decanters separate stickwater (protein), crude oil, and sludge at >95% purity.

Drying

Disc dryers or Ring dryers for low-temperature drying (<90°C) preserving protein solubility.

Packing

Packaging personnel can package fish meal in bags or bulk containers for transportation and storage.

Why do you need a

fish meal processing line

Automated machines and equipment in a fish meal processing line save time and reduce manual labor, ensuring efficient fish processing, consistent product quality, and low spoilage risks.

In addition, custom processing lines provide flexibility and scalability to meet specific production needs.

How Fishmeal Processing Improves Capacity and Efficiency

The production line typically includes equipment for cooking, pressing, and drying, as well as ancillary equipment for handling and processing the raw materials and finished products.

How to deal with the waste gas produced in the fish meal production plant

In order to manage the waste gas produced, a fish meal plant production can install a waste gas treatment system. This system typically comprises a cyclone dust collector, a bag filter, and a scrubber.
