In the modern aquaculture industry, floating fish feed has become a mainstream feed type due to its advantages, including long suspension time in the water, minimal nutrient loss, and easy observation of fish feeding habits. Its production process relies on the coordinated use of specialized equipment, precisely controlling physical and chemical changes to achieve optimal floating performance, quality, and nutritional balance. The entire process encompasses key steps such as raw material processing, mixing and conditioning, extrusion granulation, drying, and cooling. Equipment parameters and operating standards are closely aligned at each stage, jointly determining the final feed quality.

Technical Features:

1. The core objective of the floating fish feed equipment process is to produce feed with a density lower than that of water (0.9-0.95g/cm³), a floating time of 12 hours or longer, uniform particles (2-8mm in diameter), and a nutritionally balanced diet. This meets the feeding needs of different fish species (such as grass carp, sea bass, and ornamental fish) and at different growth stages. Compared to submerged feed processes, its technical features are significant:

2. Porous Structure Forming: Through the high temperature and high pressure of the extruder, a honeycomb porous structure is formed within the feed, fundamentally achieving floating performance.

3. Precise Parameter Closed-Loop Control: From raw material particle size to extrusion temperature and drying moisture, every step is monitored in real time by sensors and a PLC system to ensure stable parameters.

4. Protection of Heat-Sensitive Nutrients: A combined "low-temperature conditioning + post-spraying" process minimizes the damage to heat-sensitive nutrients such as vitamins and fish oil caused by high temperatures, thereby preserving the nutritional value of the feed.
