Currently, the pain points of shrimp feed products are high powder content, poor water stability, and irregular particle lengths. Mufeng has newly launched an expansion shrimp feed process, which is essentially different from traditional conditioning. Among them, expansion conditioning increases mechanical energy input: under a certain pressure, the material undergoes strong extrusion and kneading, causing changes in the physical and chemical indicators of starch, protein, fat, etc., in the feed. According to the results feedback from application cases, using the expansion pretreatment process to produce shrimp feed has several advantages:
Expansion pelleting improves starch gelatinization, which is conducive to digestion and absorption; meanwhile, it has better adhesive properties, improving the particle quality and making the particles more water-stable, thus avoiding feed deposition and waste, as well as water eutrophication. In addition, the expansion system configuration produces finished pellets with a smoother surface, flatter cutting edges, and more stable water stability compared to the standard conditioning configuration.
After process optimization application, the powder content is controlled at 0.05%.
Compared with the traditional process, the pelletizer operates more stably, with lower current, less head material, fewer slipping times, and lower pressure on returned material; labor costs can also be reduced.
It expands the application range of cheap raw materials, reducing the cost of raw materials.
