Food Powder Flow Solution

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.

Make the powder flow — not just add one more ingredient.
Seasoning and spice powders kept free-flowing with food-grade silica
Food-grade anti-caking silica keeping seasonings, spice blends and powdered beverages free-flowing — preventing lumping and bridging through humidity and long-distance export.

Core value

  • Reduce caking, bridging and unstable discharge so blending, dosing and packing run smoothly.
  • Improve powder flow and dispersion stability, cutting segregation, rework and batch variation.
  • Help customers find the right grade faster through small samples and multiple grades, lowering trial and switching risk.

On VS-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.

Who it's for

  • Local seasoning, powdered-beverage, soup-powder and compound-seasoning plants.
  • Food OEMs, co-packers, repackers and importers of raw materials for own use.
  • Small and mid-size ingredient customers who need small trial samples, full documentation and gradual onboarding.

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.

Technical FAQ

Food powder flow — common questions

Published industry literature reports 0.5–2% for hydrophilic precipitated silica used as an anti-caking agent in powder blends. That range is a reported industry starting point, not a Vistasilica specification. The working load depends on the water activity and fat content of the host powder, so it should be set by trial against your own storage and transport conditions.
Anti-caking performance depends on the moisture and fat profile of the host powder, not on the silica alone. A blend that forms recrystallised salt bridges during storage needs a different particle size and surface area from one that cakes through fat migration. Screening the powder profile before fixing a loading is what separates the two cases.
VS-F120 Flow Aid is the anti-caking and flow grade: D50 5–12 µm (ISO 13320) with 45 µm sieve residue ≤ 0.05% (ISO 2591-1). VS-C200 Carrier is the liquid-carrying grade: DOP 240–290 g/100 g and BET 170–230 m²/g. Use VS-F120 to keep an existing powder moving, VS-C200 to turn a liquid into a powder.
