We are pleased to announce the successful shipment of a 500 kg/h high-end fish feed production line to Poland. This project represents another step forward in our commitment to providing advanced, reliable and efficient food and feed processing machinery to customers worldwide.
Designed to meet the customer’s production requirements, this project features a complete fish feed manufacturing solution covering the entire process from raw material mixing to finished product packaging. With carefully selected equipment, advanced processing technology and an integrated production configuration, the line is designed to deliver consistent product quality, efficient operation and reliable long-term performance. It is also flexible enough to support a range of fish feed formulations and pellet specifications, allowing the customer to adapt production to different market and feeding requirements.
1. Complete Production Line Configuration
Unlike a single-machine purchase, this project involves a complete production line with coordinated equipment for each processing stage. The automatic fish feed production process starts with raw material mixing and continues through extrusion, drying, vacuum coating and final packaging. Each machine plays an important role in ensuring smooth material transfer and consistent processing throughout the production line.
The main equipment includes:
-
Raw material mixing machine
-
Screw conveyor and feeding system
-
Fish feed double-screw extruder with conditioner
-
Air conveying system
-
Multi-layer drying machine
-
Cooling system
-
Vacuum coating and flouring machine
-
Automatic packaging machine
The integrated design helps reduce manual handling, improve production efficiency and provide a more organized manufacturing workflow. Because the equipment is configured as a coordinated line rather than a collection of separate machines, material flow between stages is smoother, and the overall production process is easier to manage and maintain.
2. Raw Material Mixing – The Foundation of Consistent Quality
The fish feed production process begins with the raw material mixing system.
Different ingredients, such as grains, protein sources, starch and other nutritional components, need to be blended according to the customer’s specific fish feed formulation. Accurate proportioning and uniform mixing are essential because they help ensure that each batch of raw materials has a consistent composition. This provides a stable foundation for the subsequent extrusion process and helps maintain product consistency.
A well-designed mixing stage also supports better utilization of ingredients and contributes to more predictable results in downstream processing, where variations in the raw material blend can affect extrusion stability, pellet quality and final feed performance.
3. Extrusion Technology – Shaping High-Quality Fish Feed
After mixing, the prepared raw materials are fed into the fish feed double-screw extruder.
Extrusion is one of the most important stages in fish feed manufacturing. Under controlled temperature, moisture, pressure and mechanical processing conditions, the mixed ingredients are cooked and formed into pellets through specially designed dies. The conditioner helps prepare the raw materials before extrusion, while the twin-screw extruder provides stable mixing, shearing and shaping conditions for consistent pellet formation.
By adjusting the processing parameters and die specifications, manufacturers can produce fish feed pellets in different sizes and shapes to meet the feeding requirements of various fish species. The extrusion process also helps improve the digestibility and physical properties of feed ingredients. For floating or sinking fish feed, the production parameters and equipment configuration can be adjusted according to the customer’s product requirements and formulation.
4. Multi-Layer Drying Machine – Ensuring Stable Moisture Content
Freshly extruded fish feed pellets contain a certain amount of moisture and need to be dried before further processing.
This fish feed production line’s drying process helps reduce moisture content, improve product stability and prepare the pellets for the subsequent coating stage. Proper drying is particularly important for finished feed quality, as moisture content directly affects storage stability and product shelf life. The multi-layer drying configuration supports uniform drying and efficient use of production space, while the cooling system helps bring pellets to a suitable temperature before coating and packaging.
5. Advanced Vacuum Coating and Flouring System – Adding Oil and Nutrients More Effectively
One of the highlights of this project is its high-end vacuum coating system.
In fish feed manufacturing, oil and other liquid nutritional ingredients are often added after extrusion and drying. The vacuum coating machine provides an effective way to apply these ingredients to the feed pellets. During the vacuum coating process, air inside the pellets is partially removed under vacuum conditions. When the system returns to normal pressure, the liquid ingredients can penetrate into the pellet pores more effectively.
Compared with conventional surface spraying alone, vacuum coating helps improve oil absorption and distribution within the pellets, depending on the product structure and process parameters. This is especially valuable for producing high-energy fish feed and products requiring a higher oil content. The system helps manufacturers achieve more controlled coating results while improving the overall quality and nutritional value of the finished feed. The flouring function further supports product presentation and surface treatment where required.
6. Automatic Packaging Machine – Completing the Production Process
After coating and cooling, the finished fish feed pellets are transferred to the automatic packaging system. The packaging machine weighs and packs the finished products according to the required bag specifications. Automatic packaging helps improve packing efficiency, reduce manual labor and maintain consistent package weights. With the packaging system integrated into the complete production line, the customer can establish a more efficient workflow from raw material preparation to finished product delivery.
7. From China to Poland – Another Successful Project Delivery
Before shipment, all machines underwent production preparation, inspection and packing procedures to ensure they were ready for international transportation. Each piece of equipment was carefully packed and arranged for container loading, with attention to protection during long-distance shipping. From mixing and extrusion to vacuum coating and automatic packaging, this 500 kg/h fish feed production line reflects our focus on complete solutions, advanced equipment configuration and practical manufacturing requirements.
We believe that successful cooperation is not simply about supplying individual machines. It is about understanding the customer’s production needs and providing an integrated solution that supports their business development. We look forward to seeing this production line installed and operating successfully in Poland.
