Raw Materials Crushing
Purpose
The raw materials crushing stage breaks raw materials into smaller pieces. The primary crushing is designed to reduce the particle size difference of raw materials, making it convenient for the subsequent production processes. Given that aquatic animals have low feed intake, short digestive tracts and poor digestive capacity, aquatic feed requires extremely fine granularity. Therefore, a secondary crushing process is usually needed to meet this strict requirement.
Main Equipment
Feed Raw Material Hammer Mill

Oil Spraying
Purpose
After drying, pellets go into the oil‑spraying system. AOWIN equipment coats feed pellets with oil, vitamins and flavor enhancers. This meets aquatic animals’ energy requirements, protects heat‑sensitive nutrients, improves feed palatability and lowers powder residue.
Main Equipment
Oil Spraying Machine


IMG_0044_副本

Feed Pellet Cooling

Purpose
After the oil spraying process, feed pellets reach a high temperature and become prone to breakage. To avoid losses during this stage, the pellets must be cooled. AOWIN adopts a counterflow cooler for this process, ensuring the temperature of cooled pellets is no more than 3-5°C higher than the room temperature.

Meeting Nutritional Needs

This fish meal production line is highly adaptable to a wide range of raw materials, capable of processing various feed ingredients to achieve optimal feed formulations. It produces nutritionally balanced fish feed that meets the nutritional needs of fish throughout their entire life cycle, enabling precise feeding.

Improving Absorption Rates

This process involves steam pretreatment of the feed to increase the degree of starch gelatinization and denature proteins, thereby enhancing the digestibility and absorption of the feed. Additionally, proper pretreatment facilitates pelleting and extrusion while maintaining pellet integrity, reducing feed loss and improving utilization efficiency.

High Level of Automation

We provide automated fish feed processing line solutions. The entire process, from raw material processing to finished product packaging, is fully automated and only requires 1-2 operators. This significantly reduces labor costs and boosts productivity.

Reduction of Water Pollution


Non-disintegrating feed reduces organic pollution in water and makes it easier to control harmful indicators such as ammonia nitrogen and nitrite. This provides fish with a stable, clean growth environment and fundamentally prevents the occurrence of diseases.

Reduction of Feed Waste

This production system can produce fish feed in various sizes. The feed, with appropriate size and improved texture, is easier for fish to consume. With a water resistance of up to 12 hours, it minimizes waste during feeding, reducing feed loss by 20% to 30%.

Balanced Nutrition

Many vitamins, enzymes, and probiotics are thermally unstable. Adding these additives to the mixer will result in significant loss after conditioning, granulation, and extrusion expansion. Spraying them directly on the surface of pellet feed after granulation and expansion greatly reduces the loss of these additives.

High Stability in Water

This is the most important criterion for shrimp feed. The solution adopts processes such as grinding and high-temperature tempering to fully gelatinize starch, forming a natural binder. This allows feed pellets to maintain their shape in water for 12 hours without disintegrating, preventing nutrient loss.

Efficient Mass Production

Compared to traditional production methods, this production system can increase unit output by 15%. It features higher raw material utilization, reducing waste and improving production efficiency. Especially the highly automated production lines can maintain stable output for a long time.

How to Choose Fish Feed Manufacturing Machinery?

Due to the small intestines and stomachs of fish and their poor digestive and absorptive capacity, the processing technology of aquatic feed is much more demanding than that of livestock and poultry feed. To produce high-quality aquatic feed, we must rely on scientific and reasonable processing technology, combined with advanced, reliable and stable processing machinery. In this regard, the selection of processing equipment is particularly critical.

1Precision Processing of Feed
Due to aquatic animals’ short digestive tracts, aquatic feed requires smaller crushing particle size than livestock feed (e.g., eel/shrimp feed needs 80-120 mesh). Our ultra-fine grinders meet this requirement to improve digestibility.
2High-Protein Feed
Livestock feed protein content is usually below 20%, while aquaculture feed is 30%-40%. Our equipment ensures uniform mixing and stable pelleting to maintain nutritional balance and high protein content.
3Water-Resistant Feed
Aquatic feed needs good water resistance to avoid disintegration. Our equipment uses scientific tempering and pelleting processes to ensure high water resistance and nutrient retention.
4Production Cleanliness
Feed purity is crucial to prevent water pollution and fish diseases. Our production line has a negative-pressure dust collection system and high-temperature sterilization to ensure feed safety.
5Cost Savings
Our high-efficiency, energy-saving production lines and automated equipment reduce feed loss and lower unit energy consumption by 20%, cutting overall production costs.
