Sweco® PharmASep™ Solves Unique Challenges of Pharmaceutical Industry

For more than 60 years, Sweco® has been on the leading edge of particle separation technology. Now, with the PharmASep™ family of filter/dryer machines, the company has raised that expertise to a new level, developing a revolutionary separator that solves a number of challenges unique to pharmaceutical applications.

The new PharmASep combines engineering modifications to screens, spouts, clamping assemblies and other design elements that significantly increase convenience, safety, precision and productivity in critical applications.

Combining Sweco's patented Vibro-Energy® separation with Vibro-Dry™ vacuum drying technology, the PharmASep filters and dries product efficiently and effectively in one machine.

The result is a truly sanitary separator manufactured to cGMP Standards that can be used for wet or dry processes and handles up to 100 liters of solid product (particle sizes of 1 micron and up). With Class 100 Clean Room design and CIP/SIP capability, the PharmASep operates on a batch or semi-continuous basis and also can provide highly efficient size separation of dry powders.

The SaniSep Plus “No-Gap” design by SWECO



The PharmASep offers a number of unique characteristics that address the specific challenges of the pharmaceutical industry. The sealed pressure vessel design, with a highly polished crevice-free interior, delivers high-yield product recovery while containing potent pharmaceutics for safer handling.

The "no-gap" design allows the unit to be cleaned in place without disassembly, significantly improving productivity while maintaining verifiable standards. The new sloped spout design results in more efficient discharge of the product, minimizing the risk of cross-contamination between batches.

Easy-to-operate clamp assemblies are secure enough to hold both pressure and vacuum. Tri-clamp assemblies are provided on all ports for optimal containment, more efficient external connections and, when capped, to effectively hold the pressure when steam sterilizing in place (SIP). Based on configuration, geometry and material used, 30 PSI of pressure or 15 PSI of vacuum can be applied.

By adjusting speed and direction, the electronically controlled motor can customize distribution patterns of feeding material on the screen, significantly improving the efficiency of screening and dewatering. The fully enclosed motor facilitates contaminant-free operation in a clean-room environment. A vacuum outlet, connected to the fully encapsulated motor, transfers produced particles from the motor environment to the outside of the process room while providing ventilation to cool the sealed motor area.

The optional QuickChange™ Screen Kit simplifies screen removal for quick and easy screen maintenance.

The whole system is enclosed and can be adapted as part of the operation in a semi-automated manner, making validation of the process easier.

For wet sieving (slurry) applications, the PharmASep was designed to:

•control residence time on the screen by blocking the spout

•dewater the product on screen

•apply vacuum for as long as necessary to dry the product on screen while vibration is maintained

•unplug the spout(s) and discharge the dried product.

This capability replaces the traditional transfer of the wet slurry to a vacuum dryer, eliminating a labor- and cost-intensive step in the sieving process that can compromise the integrity of the separated product.

Now in use in the United States and Europe, PharmASep is available worldwide and is supported by an experienced, international team of field service engineers. Sweco offers its customers a convenient rental program for performing field tests.

With more than 60 years of separation technology experience, Sweco serves the pharmaceutical, chemical, paper and many other industries with a complete line of separation, sizing and milling equipment.
