Application
As carrier, flow-free aid and anti-caking for animal feed additives
Silica plays a crucial role in enhancing the flow performance and preventing agglomeration of powdered additives such as mineral premixes and vitamin premixes. When used as a flow aid and anti-coalescer, silica particles are relatively smaller, and the amount added is lower. On the other hand, when utilized as a carrier, silica particles are larger, allowing for more than % of adsorption.
The addition of silica to powdered additives ensures that they can be administered more evenly and accurately. This results in improved processing efficiency and reduced downtime, which can be costly for manufacturers. By using silica as a carrier for feed additives, liquid ingredients and additives can be converted into free-flowing dry powder and premixes. This allows for high loading of animal feed ingredients and additives while maintaining consistency.
Overall, feed manufacturers can benefit significantly from the use of silica carriers, as it allows for more efficient mixing and processing during production. The use of silica carrier not only improves the flow properties of the feed but also helps in evenly distributing valuable additives throughout the feed, which ultimately benefits the animals’ health and well-being.
