Pharmaceutical Lab Case Study

The sieving and de-agglomeration of 1 kg batches of pharmaceutical powders for a large pharmaceutical manufacturer. The material needs to be sieved in 5 minutes through U.S. 45 or finer mesh.
Most of the samples have agglomerates. Course particles need to be removed from the samples.

VORTI-SIV Model RBF-10 gyratory lab sieve utilizing a variable speed frequency control with our SFA Ultra-sonic deblinding kit. In addition, stainless steel disks are used to break agglomerates.

Minimum Clean-up and Product Changeover-
Only two (2) stainless steel sanitary product contact parts enables fast change-over. An optional removable dome or scoop feed cover enables dust-free sieving.

De-Agglomerating Sieve-
Four (4) highly polished stainless steel 2" diameter disks are put on the screen surface to break the agglomerates. The RBF-10 mechanical gyration causes the disks to randomly impact agglomerates, reducing all lumps to fine powder.

SFA Deblinding Kit-
A single phase 110/220 volt Ultra-sonic auto-tuned processor with a screen mounted transducer supplies additional high frequency energy. Screen blinding of the pharmaceutical powders is eliminated even with difficult powders such as magnesium or calcium stearate, etc.

Variable Speed-
The RBF-10 utilizes a 3450RPM electric motor. A digital frequency inverter enables the mechanical vibration to be controlled from 800 to 3450RPM. This feature improves the processing efficiency of each product sample
