PSL: Mixing Filter Dryer Agitator

Posted in: , on 18. Jul. 2011 - 17:34


Achieve efficient cake drying during your filtration and separation process with the advanced design of the Powder Systems Ltd (PSL) filter dryer agitator.

The core of good agitated nutsche filter dryer (ANFD) performance relies heavily on the agitator design. The PSL agitator has been refined over a 22 year period to provide very robust performance under a variety of conditions. This is achieved by a series of sharp curved blades with spaces at different centres of each arm.

When moving and lifting the cake product between the gaps within the filter dryer agitator the product moves at a lower velocity and is subsequently swept by the second arm of the blade achieving efficient mixing by differential velocities.

PSL’s curved agitator blades also achieve penetration into difficult cakes without undue product stress. The agitators are always fabricated in one piece with the shaft welded to the arms which removes any direct leak path of heat transfer fluid through a bolted joint between the shaft and arms.

PSL is a centre of excellence in the design and manufacture of Filter Dryers since 1989. With a full range of sizes and specifications to meet all requirements, from chemical development to bulk production, PSL agitated nutsche filter dryers provide the total reliability needed in the pharmaceutical industry. Years of experience in supplying filter dryers to the major pharmaceutical companies globally has enabled all design aspects to be refined, including:

• Agitator Design

• Full CIP Systems

• Bayonet Base

• Bellow Purge

• Base Design

• Vessel Jacketing

• Integrated Containment

PSL’s engineering team and process experts draw from vast experience in the containment field to design seamlessly integrated contained discharge solutions.
