Applications and Uses of Feed Grade Silica
It is widely used in feed, animal nutrition, premix, and powder additive systems. High-quality silica powder can effectively help solve the following problems:
Prevent caking of feed powders
In high humidity environments, feed powders contain hygroscopic components, and liquid bridges easily form between particles. KosNature feed-grade amorphous silica has a high surface area and can absorb trace moisture, reducing the risk of particle adhesion.
Improve discharge efficiency and production time
When powder flowability is poor, bridging can occur in storage silos. Our anti caking agent reduces friction and adhesion between particles.
This helps improve discharge, conveying, and packaging efficiency.
Maintain better mixing performance
In systems with trace ingredients and mineral feed, poor flowability affects mixing uniformity. KosNature silica powder helps maintain better dispersion and improves consistency in animal nutrition products.
Improve batch-to-batch stability
In feed processing, anti caking materials often vary in performance due to different sources. KosNature controls particle size, surface area, and adsorption capacity of silicon dioxide, ensuring stable and consistent performance across batches.

Silica: The Ultimate FAQ Guide
Silicon dioxide powder, especially amorphous silica or precipitated silica (E551), is widely used in feed systems as an anti caking agent and flow agent. It can absorb trace moisture, reduce particle adhesion, and help maintain stability during mixing, conveying, and packaging.
Нет. Silicon dioxide does not provide nutritional value. The silica powder, which is widely used as an anti-caking agent in feed systems.It is a functional processing aid or animal feed additive used for improving flow and stability.Your nutritional formulation will not be significantly affected by its use.
The typical dosage of silica powder ranges from 0.1% Кому 5.0%, depending on formulation, humidity, and powder characteristics.
For use as an anti caking agent (E551), the common dosage is 0.5% Кому 2%.
You can adjust the dosage based on flowability and caking conditions.
Да, it may. Excessive use of silicon dioxide can affect powder handling properties and mixing performance.
It may also increase cost unnecessarily.
We recommend determining the optimal dosage through testing, typically ≤ 2%, rather than increasing blindly.
In many cases, yes. If your current issue is inconsistent performance, silica can offer better stability.
Однако, full replacement depends on your formulation and cost requirements.
We usually suggest evaluating the following three aspects:
First, whether the powder flows more easily.
Second, whether caking is reduced after storage.
Third, whether mixing uniformity is improved.
If these aspects show clear improvement, the selected silica powder grade is likely suitable.
We recommend preparing two sample groups.
One without silicon dioxide, and one with the recommended dosage of anti caking agent (E551).
Store them under the same temperature and humidity conditions.
Observe flowability changes after 48 hours or longer.
This method is simple but highly practical.
Our engineers usually require the following information:
Product type
Current caking condition
Production environment humidity
Storage time
Packaging method
Whether it is used in premix or mineral feed
Target dosage
Regulatory document requirements
The more detailed the information, the more accurate the recommendation from our silica manufacturer team
Да. We recommend starting with small sample testing.
After validation, you can proceed to trial orders or bulk purchasing of bulk silica.
