For food processors genuinely in powder compounding, dry blending and post-spray-drying — solving real caking, flow, dispersion and batch-stability problems rather than selling generic filler.
On CS-F120, a fine particle size (D50 5–12 µm, ISO 13320) with 45 µm sieve residue ≤ 0.05% (ISO 2591-1) supports free flow and anti-caking in seasoning powders and dry blends.
Typical benchmarks: Evonik food-grade SIPERNAT® series, W. R. Grace SYLOID® food-grade anti-caking and carrier grades, PQ Corporation high-surface-area silica gel / silica for food ingredients.
We don't replicate brand premiums. We enter through niche applications, second-source / backup supply and multiple grades, and differentiate with profile screening, problem diagnosis and sample conversion.

| Test dimension | What to watch | What it tells the customer |
|---|---|---|
| Anti-caking | Whether bridging, hard lumps and clumping are reduced | Judges shelf and storage stability |
| Flowability | Whether discharge, dosing and mixing uniformity improve | Judges production efficiency |
| Dispersibility | Whether local agglomeration and segregation are reduced | Judges batch consistency |
| Lab to scale-up | Whether lab and pilot results are consistent | Judges manufacturability |
