Feed Grade Silicon Dioxide | Improve Pellet Stability & Reduce Nutrient Leaching Special silica solution for aquafeed production. Enhances pellet water stability, reduces nutrient dissolution loss, improves feed utilization efficiency and reduces water pollution. Product Information Aquaculture feed has higher requirements for water stability and nutrient retention. Poor water resistance of feed pellets will lead to rapid dissolution of nutrients in water, reducing feed utilization rate and causing water environment pollution. Zhongqi Shandong Silicon Material Co., Ltd. provides professional feed-grade silicon dioxide solutions for aquafeed production. Our aquafeed-grade silica can improve the microstructure of feed pellets, enhance the bonding force between particles, and effectively improve the water stability of pellets. It prolongs the disintegration time of feed in water, reduces the loss of water-soluble nutrients, and ensures that aquatic animals can ingest complete nutrients. At the same time, as an anti-caking agent and flow aid, it improves the processing performance of feed powder in the production process, improves the uniformity of mixing and granulation, and helps improve the appearance quality and finished product rate of feed pellets. The product meets feed safety standards, will not affect the health of aquatic animals, and will not cause adverse impact on water quality. It is suitable for all kinds of freshwater and marine aquaculture feed production.

Reduce Nutrient Leaching Loss Reduces the dissolution rate of water-soluble nutrients such as vitamins and minerals in water, ensures that more nutrients are retained in the pellets, improves feed utilization efficiency, and reduces breeding costs. Improve Processing Performance Improves the flowability of mixed powder, makes the feeding of granulation equipment more uniform, improves granulation forming rate and pellet surface smoothness, and reduces the content of finished powder. Aquatic Safety Assurance Ultra-low heavy metal content, no toxic and harmful substances, will not accumulate in aquatic animals or cause water quality deterioration, fully meeting the safety requirements of aquaculture production. Product Advantages & Usage Instructions Core Advantages Significantly improves water stability of aquafeed pellets and reduces dissolution loss Improves feed utilization rate, reduces breeding cost and reduces water pollution Optimizes granulation processing performance and improves finished product rate Stable chemical properties, no adverse effect on aquatic animal health Suitable for all kinds of fish, shrimp, crab and other aquatic feed formulas Usage Instructions 1.Recommended addition amount in aquafeed formula is 0.2% – 1.0%, which can be adjusted according to formula composition and pellet hardness requirements. 2.Add together with other powder raw materials in the mixing stage, and ensure uniform mixing before entering the granulation process. 3.For high-protein and high-fat formulas, the dosage can be appropriately increased to improve pellet structure and water stability. 4.For extruded feed, it can be added to the raw material formula together, and adapt to the extrusion process conditions. 5.Store in a dry environment to prevent moisture from affecting the processing performance. Application Scenarios Shrimp & Crab Feed Production Especially suitable for crustacean aquafeed with high requirements on water stability. It prolongs the time that feed pellets keep complete in water, meets the feeding characteristics of slow feeding, and reduces feed waste. High-density Freshwater Fish Feed For high-density intensive aquaculture, it improves feed utilization efficiency, reduces water quality deterioration caused by feed dissolution, and maintains good breeding water environment. Marine Fish Compound Feed Meets the requirements of marine aquaculture for feed quality, reduces nutrient loss in seawater, and ensures healthy growth and feed conversion rate of marine fish. Extruded Aquafeed Production Suitable for extruded feed production process, helps improve the expansion uniformity and particle structure of extruded feed, and enhances the water stability of floating or sinking feed.
