Vibro Sifter for Pharma Industry

In pharmaceutical manufacturing, a vibro sifter for pharma industry use controls particle size and removes oversize or foreign material before the next process step. Consistent particle size improves blend uniformity, flow into compression and filling machines, and ultimately content uniformity and weight variation of tablets and capsules.

Pharmaceutical manufacturing where vibro sifters are used for granule sifting

Where Sifting Happens in Oral Solid Dosage Lines

Dispensing: APIs and excipients are sifted to break lumps formed during storage.
Pre-granulation: powders are sifted together for a uniform dry mix.
Post-drying: dried granules from a fluid bed or tray dryer are sifted; oversize goes to a multi mill.
Lubrication: magnesium stearate and glidants are sifted through a fine screen before blending.
Pre-compression: the final blend may be check-sifted.
