Key technical points of fish feed extrusion production line

- Formula Adaptability: Farmed animals are sensitive to the ratio of animal and plant proteins; it is recommended that animal protein account for no less than 60%;
- Oil Addition Method: Fish oil is added via a post-spraying process to prevent oxidation loss at high temperatures;
- Anti-Mold Measures: Calcium propionate solution (0.3%) is sprayed before packaging to inhibit mold growth;
- Water Quality Simulation Test: A water suspension test is conducted before production to observe the feed disintegration time.

For example, a loach seedling starter feed production line with an annual output of 1,000 tons would require a total equipment investment of approximately 800,000 to 1.2 million RMB. The extruder and dryer account for approximately 40% of the total cost. It is recommended to prioritize modular equipment to facilitate future capacity expansion. Power and steam consumption are the primary operating costs, with a combined energy consumption of approximately 120-150 RMB per ton of feed.

Common Problems and Solutions
-Low pellet floatability: Check the extruder's die aperture for wear and adjust the moisture content of the feed.
-Feed mold: Check the temperature and humidity control during the drying and cooling process. It is recommended to use aluminum foil composite packaging.
-Poor feeding rate: Optimize the attractant ratio. Try adding 0.2%-0.5% nucleotides.

MIKIM's fish feed production line can meet your needs:

Crushing system
Crushing is the operation of reducing raw materials particle size and increasing its specific surface area, which and improve the processing quality and work efficiency of subsequent process steps such as batching, mixing, and pelleting.

Screw elevator
Screw elevators are mainly used to transport powdery, granular and small block materials, chemicals, etc. They are not suitable for transporting materials that are easy to deteriorate, sticky and easy to agglomerate.

Raw material mixer
The Raw material mixer is used for mixing the ingredients, you can mix the rich ingredients well, you can also add a variety of nutrients, so that the nutrition is more balanced.

Hopper
A hopper is a material conveying equipment, which is mainly used to convey and process materials. It can convey materials from one place to another, including horizontal conveying and inclined conveying.

Feed extruder
Aquatic feed extruder is a key equipment used in the aquaculture field to process extruded feed. It realizes material extrusion and molding through the principle of screw extrusion.

Dryer
Drying is to reduce the moisture content in the product, thereby improving the stability and shelf life of fish feed products.

Wind conveyor
Pneumatic conveying device is a kind of transport device that uses air as the transport medium to transport materials in a closed pipeline.

Drum Seasoning Machine
The equipment is made of stainless steel, which makes the work of feed seasoning convenient, and truly realizes fully automated production, saves time and effort, and flavors the tasteless feed to help animals better eat and absorb.

Counterflow Cooler
Counterflow coolers are mainly used for feed cooling production lines with large feeds. The material is cooled in layers from bottom to top by the inhaled air. The air intake area is large, the cooling effect is good and the effect is significant.

Silos
Silos play a vital role in the feed production and storage process. Not only can they store bulk feed in large quantities to ensure continuous feeding of the production line, but they can also protect the feed from adverse effects such as moisture, mildew and insect pests through their sturdy structure and reasonable design.
