Sweco's PharmASep is a fully contained Vibro-Energy Filter/Dryer suitable for aseptic processes in the pharmaceutical industry. With a design that eliminates gaps, crevices and hidden areas, the PharmASep proves valuable to those processes handling potent and/or toxic substances where containment is an important issue.
The PharmASep allows batch processing of up to 15kg of solids as well as continuous processing in pilot plants and full production environments. For both wet and dry processes, the sealed pressure vessel delivers high yield product recovery while containing potent pharmaceuticals for safer handling. Unique Vibro-DryTM Technology, developed by Sweco, allows vacuum drying to occur within the PharmASep while the product is gently tumbled on the screen surface, accelerating the drying process and reducing formation of agglomerates.
The PharmASep, with clean-in-place and steam-in-place capabilities, enables users to properly clean the machine without the need to disassemble and re-assemble, reducing downtime and ultimately increasing productivity. In the case of wet sieving, the PharmASep can dewater the product on the screen, apply vacuum, dry and discharge the dried product, eliminating the necessity for separate vacuum drying. |

Sift, scalp, de-lump and de-water virtually any bulk solid or slurry
The Kason Centri-Sifter® is a versatile, high capacity, compact and economical centrifugal sifter used for screening a wide variety of powders or granular materials, including chemicals, plastics and resins, foods, dairy products, pharmaceuticals and biologicals. This equipment is the ideal choice for continuous scalping of dry or moist materials, even those that tend to ball or agglomerate as these units delump and deagglomerate while screening. The Centri-Sifter Screener is also extremely effective as a liquid/solids separator.
Centri-Sifter centrifugal sifters are designed for gravity-fed applications, and for sifting in-line with pneumatic conveying systems. They are available as single and twin models and low profile units, and offered in a broad range of standard, modified, and custom configurations. All are available with professional belt drive or direct drive. Units may be free-standing or adapted for easy mounting on new or existing process equipment. On gravity-fed models, a large access professional door allows inspection and cleaning. In-line pneumatic units offer large ports for inspection. Removable end housings allow rapid cleaning and screen changes. |

The Cleveland Professional vibrator Company, along with its affiliate HK Technologies, introduces a new line of ultrasonic screening equipment utilizing dual vibrator drives. This dual motor separator provides for three control variables: vibrator force, frequency, and drive angle. This design concept results in a three dimensional motion thus allowing for greater throughput of difficult to screen products. This distinctive vibratory action coupled with HK Technologies unique ultrasonic deblinding system provides a screener that can handle many difficult screening applications. The transducer is attached to the aluminum rim with the wire cloth attached on the bottom (like a sieve). Unlike competitive products, the ultrasonic vibration transfers from the rim to the wire cloth to facilitate the throughput of fines by introducing high frequency movement to the individual wires. Helps eliminate blinding. This unique transfer increases the life of the wire cloth as traditional methods allow heat from the transducer to prematurely fail the fine wires.
Models are available in 24, and 36" diameter screen sizes. Screen sizes down to 635 mesh (20 micron). All screens are re-screenable.
Cleveland Vibrator also manufactures a complete line of brute force screeners as well as fine powder, laboratory screeners. Ask about our HyBrute, a brute force screener with the addition of ultrasonic deblinding.
