V Type Mixer Blender Sealed Operation Vacuum Feeding for Pharmaceutical Processing

Low concentration blending is a primary application for the V shape mixer. The asymmetric tumbling action creates a folding and splitting flow pattern that distributes minor components uniformly across the batch. For 1 percent active loading, we recommend a pre blend step where the active is mixed with a small portion of excipient before adding to the full batch, which is standard pharmaceutical V mixer protocol and achieves relative standard deviation below 5 percent in routine production.

There is no internal agitator, blade or chopper inside the V shape mixer. Material moves only by gravity tumbling as the cylinder rotates at 8 to 12 rpm. This is the lowest shear mixing mechanism available for batch blending and is specifically chosen for film coated granules, effervescent tablets and fragile particle applications.

The CWV 2500 covers up to 500 kg working volume per batch. Specify the CWV 2500 paired with the CWVC 4 vacuum conveyor. We supply the conveyor connection flange dimensions at order stage so your installation team can confirm fit with the existing conveyor outlet.

The cylinder opens at the discharge port for full interior access. The stainless steel interior surface has no dead corners in the V geometry and wipes clean with a solvent or water rinse. For strict cross contamination control between incompatible formulations, a brief dry tumble cycle with an inert carrier after cleaning confirms the interior is clear before the next batch.

Standard mixing time is 4 to 10 minutes. For blends where component particle sizes differ by more than a factor of five, add 2 to 3 minutes to the standard cycle and verify uniformity with a three point sample at 8 and 12 minutes during the first production run. Significant density or size mismatch benefits from a reduced batch fill level, which increases relative tumbling motion per unit mass and improves uniformity.
