Mixing is a fundamental process operation, but how it is done has a critical effect on production – as the examples here highlight. Sean Ottewell reports.
Das Vermischen ist ein grundlegender Arbeitsgang, aber die Art, auf die er ausgeführt wird, hat einen entscheidenden Einfluss auf die Produktion, wie die Beispiele zeigen. Sean Ottewell berichtet.
Le mélange est fondamental dans un processus de transformation, mais les exemples suivants soulignent que la manière dont il est effectué est décisive pour la production. Selon Sean Ottewell.
Mixing is critical to process success
G
oing from the laboratory to production scale has always been a challenge. With the new Silverson Verso it’s become less of one. The Verso reproduces what we can do
on a production scale. David Rothman, director of Silverson Machines,
explains: “It gives clients the ability to start scaling accurately with smaller volumes than they were able to previously.” A bench top in-line mixer, the Verso is ideal for
pilot-scale or laboratory applications. Controlled from a digital operating touch pad, it offers excellent reproducibility when scaling up, and with a tachometer, ammeter and programmable
timer, it provides an accurate and easy method of forecasting the performance of larger in-line mixers under full-scale conditions.
Scale-up process The Verso complements Silverson’s lab range of equipment, providing the next step in the scale- up process. The 1hp machine has a self-pumping flow rate of 6.5US gallons/min (24litres/min) - depending on product viscosity (Fig. 1). “We developed the Verso as a direct response to
customer requests. Our customers wanted an interim size machine that could allow them to streamline their scale-up process,” says Rothman. “Our production scale UHS Series In-Line
