The Advantages of Extruded Aquatic Feed
1. Long Shelf Life of Feed
Extruded aquatic feed has a long shelf life due to its drying process, resulting in low moisture content and harder pellets with a reduced pulverization rate. Additionally, most microorganisms and pests are killed during the extrusion process, making it easier to store and transport.
2. Prevent Feed Waste
Extruded aquatic feed has excellent stability in water, typically not dissolving within 2 hours (some can last over 10 hours). This stability prevents the nutrients in the feed from dissolving and dispersing in the water or sinking into the mud. Additionally, leftover feed is easy to retrieve and dry, maximizing the prevention of feed waste. Experiments have shown that using extruded aquatic feed can save about 10% of feed compared to powdered or hard pellet feed.
3. Reduce Water Pollution
Extruded aquatic feed does not dissolve or sink in water, preventing leftover feed from fermenting in the water. This reduces the oxygen consumption of organic matter in the water, effectively lowering water pollution.
4. Optimize Feed Energy
It is difficult to increase the oil content in hard pellet feed, whereas extruded feed can meet the nutritional needs of aquatic animals by adding oil, which disperses evenly throughout the feed. This further optimizes the energy levels, fully satisfying the growth requirements of aquatic animals.
5.Prevent Disease Outbreaks
The high temperature treatment during extrusion effectively kills pathogens such as E. coli and Salmonella. Additionally, extruded feed has strong water (and oil) absorption properties, which facilitates the incorporation of disease-preventive medications. This helps prevent various gastrointestinal diseases caused by contaminated feed.
6.Convenient breeding management
Extruded aquatic feed can float on the water surface for a longer period, so there’s no need for a dedicated feeding platform; feeding can be done at designated spots. When fish feed, they need to come to the surface, allowing for direct observation of their feeding behavior. This enables timely adjustments to the feeding amount and provides insights into the fish’s growth and health. Therefore, using extruded aquatic feed helps in scientific aquaculture management, saving a significant amount of time and improving labor productivity.
In recent years, extrusion and expansion have gained attention as a new generation of feed processing technology in the production of aquatic feed. There are various types of fish feed extruders for aquatic feed production, such as single screw fish feed extruders, twin screw fish feed machines, dry way fish feed extruder machines, and wet way fish feed extruders.
As a professional manufacturer of aquatic feed extruders, Lima Feed Machinery will continue to provide high-quality feed production equipment and excellent service experience to both domestic and international customers.
