Offering customers more options in terms of batch sizes and processing requirements
Silverson Machines has now launched their new range of Small-scale mixers . These mixers complement the different types of laboratory and production models already available from Silverson , but importantly offer customers more options in terms of batch sizes and processing requirements .
The 150 UHS Small-Scale In- Line mixer is designed for Ultra Hygienic applications typically encountered in the pharmaceutical and biotech industries , where the smallest production scale mixers may be too large , but laboratory equipment may not offer sufficient capacity . This new model is built to the same high specification as production scale UHS mixers and can be supplied with Silverson-designed hygienic single mechanical shaft seals , which can be converted to hygienic double mechanical shaft seals suitable for pressurised flush . Ideal for batches of up to 50 litres , the mixer features a range of interchangeable workheads and screens , offering intense yet targeted high shear capability ; a conversion kit allowing it to be used as a Multistage 088 / 150 is available .
The 088 / 150 UHS is the first small-scale Multistage In-Line mixer from Silverson Machines . Matching the capabilities of production scale Multistage In-Line mixers , these mixers increase the number of shearing actions per revolution of the rotor , resulting in substantially faster mixing times and increasing the number of products that can be processed in a single pass .
The Multistage workhead features two concentric rotors and stators ; this allows customers to configure the mixer to their individual requirements . Depending on the desired results the stators can be a number of different combinations which can be quickly and easily changed to optimise processing and increase mixing versatility .
For small-scale manufacturing of higher viscosity products , Silverson has developed the 150 UHS- HV , an In-Line mixer which matches the capabilities of the production scale Silverson HV In-Line mixers . It incorporates a unique and innovative “ pumping rotor ” design that substantially increases the mixer ’ s selfpumping capacity .
High flow rates , typically around 6,500 litres / hour are maintained as viscosity
rises , often eliminating the need for an additional feed pump when processing many higher viscosity products . A range of motor options is available , including high speed , which allows the mixer to run at 9,000 rpm . This gives the mixer more power to continually recirculate higher viscosity products in the vessel .
Also part of the launch is the new FMX10 small-scale powder / liquid mixer . The FMX10 provides a simple , effective and hygienic means of powder / liquid mixing on a smallscale , with a batch size of up to 50 litres , depending on viscosity . Featuring the same pumping rotor design as the HV model , the FMX10 is able to process higher viscosity mixes , and the option of a high speed motor , capable of 9,000rpm , and Flameproof specification makes this model even more versatile .
In addition , further increasing the versatility and flexibility of these new small-scale mixers , any mixer in the new range can be supplied with a Vessel Package . The Vessel package comprises of a 50 litre vessel , vessel stand , valve and pipework . Conversion kits are also available .
