Feed Grade Silicon Dioxide | Premium Carrier & Dispersant for Feed Premixes High-purity silicon dioxide specially designed for vitamin, mineral and enzyme premixes. Excellent adsorption capacity and dispersion performance, protects active ingredient activity and ensures uniform distribution. Product Information Premix production puts forward higher requirements for additive carriers: it needs not only good adsorption and loading capacity, but also stable chemical properties to protect the activity of functional ingredients. Zhongqi Shandong Silicon Material Co., Ltd. has developed a special feed-grade silicon dioxide for premix scenarios based on in-depth research on premix production technology. Our premix-grade silica has a highly porous microstructure and high specific surface area, which can efficiently adsorb liquid active ingredients such as vitamins, choline chloride and enzyme preparations, and convert them into powder state that is easy to mix. At the same time, its excellent dispersion performance helps trace components be uniformly distributed in the premix system. The product has ultra-low heavy metal content and stable chemical properties. It does not react with active ingredients, does not catalyze nutrient decomposition, and can effectively protect the activity retention rate of functional components during shelf life. We provide particle size customization services for different premix systems. Whether it is mineral premix, vitamin premix or compound premix, we can provide matching product specifications and technical support to help premix enterprises improve product quality and stability.

Excellent Dispersion Performance Uniform particle size distribution ensures good dispersion in the premix system, helps trace components achieve uniform distribution at the micro level, and improves the mixing uniformity and accuracy of premix products. Stable Protection of Active Ingredients Chemically inert amorphous structure, no catalytic effect on vitamins, enzymes and other active ingredients. It can effectively isolate active components from adverse environmental factors and extend the retention period of product activity. Customizable for Different Premix Systems We provide particle size and specific surface area adjustment services. For different premix types such as mineral premix, vitamin premix and enzyme preparation, we can provide targeted product solutions. Product Advantages & Usage Instructions Core Advantages High-efficiency carrier for liquid active ingredients, realizing powderization of liquid additives Improves mixing uniformity of trace components and ensures accurate content per unit Protects vitamin and enzyme activity, reduces loss during storage and improves product shelf life Prevents premix caking and maintains good flowability of finished products Customizable specifications to match different premix formulas and production processes Usage Instructions 1.For liquid additive carrier use: first mix silica with liquid ingredients evenly to complete adsorption, then add to the premix system for mixing. 2.For anti-caking and dispersion aid use: add directly into the premix formula, recommended addition amount is 0.5% – 2.0%. 3.For high-viscosity liquid ingredients, the adsorption loading ratio can be tested and determined according to actual process conditions. 4.During the production process, control the mixing speed and time to avoid excessive friction affecting the particle structure. 5.Store in a cool and dry environment. Strictly prevent moisture, so as not to affect the adsorption performance. Application Scenarios Vitamin Premix Production Ideal carrier and stabilizer for vitamin premixes. It adsorbs liquid vitamins, improves mixing uniformity, and protects vitamin activity from environmental factors such as light, heat and moisture. Mineral Trace Element Premix Improves the dispersion of trace mineral elements, prevents agglomeration between mineral components, and ensures the accuracy and uniformity of trace element content in finished premixes. Enzyme Preparation & Probiotic Products Serves as a protective carrier for enzyme preparations and probiotics. It reduces the impact of environmental stress on biological activity, and maintains product stability during processing and storage. Compound Premix & Concentrated Feed Used in various compound premix products as anti-caking agent, dispersant and carrier, comprehensively improving the processing performance and storage stability of premix products.
