Ayurvedic, herbal and nutraceutical manufacturers grind dried plant material into powders and then sift them to the fineness specified in their formulation. A vibro sifter replaces slow manual sieving with a consistent, enclosed process that keeps dust down and output up.
Typical Applications
- Sifting churna after pulverising to the required fineness.
- Separating fibrous oversize for re-grinding.
- Sifting herbal extracts and granules before tableting or capsule filling.
- Check screening of nutraceutical blends before packing.
Challenges With Herbal Powders
Plant powders are often fibrous, light and sometimes hygroscopic. Fibres can mat on the screen and moisture can cause clumping. Practical measures include a larger diameter machine for more screen area, keeping powders dry before sifting, and a double deck to remove coarse fibre above the working screen.
Why Stainless Steel
Herbal products are consumed directly, and many plants follow GMP practices similar to pharmaceutical units. SS 316 contact parts and lead-free screens keep the process clean and simple to wash between herbs to avoid cross-contamination of aroma and colour.

Learn moreFrequently Asked Questions
Can a vibro sifter replace manual sieving of churna?
Yes. It gives higher output and more consistent fineness with less dust.
What mesh is used for churna?
It depends on the formulation; fine churna is often sifted in the 60–100 mesh range. Follow your product specification.
How do I stop fibre from blocking the screen?
Use a coarser top deck to remove fibre and keep powders dry; size the machine generously.
