FEATURE PUMPS, VALVES & ACTUATORS GOING GENTLE ON YEAST TRANSFER
The transfer of yeast in the brewhouse has to be carried out carefully so as not to cause damage and degredation. A MasoSine Certa pump from WMFTG is meeting this challenge at Steam Whistle brewery
Y
east is arguably the most important ingredient in the brewing process. This
single-cell organism takes simple sugars such as glucose and maltose, and produces alcohol and carbon dioxide – the latter giving beers like Pilsners its essential fizz. When yeast is pumped around a brewery, the utmost care is required so as not to cause any damage that could degrade its effect. One such brewery aware of this
important fact is Steam Whistle, where a MasoSine Certa pump from Watson- Marlow Fluid Technology Group (WMFTG) is being put to good use. The Certa 100 was originally supplied to the Toronto- based brewery as part of a brewhouse designed by Esau & Hueber. It has now been repositioned for use as a portable pump solution for the effective and reliable transfer of yeast.
QUALITY AND TASTE The pumps do not damage the all- important yeast cell, improving the fermentation and therefore the overall quality and taste of the beer. With taste providing breweries with their market differentiation, it is important that the process does not change the taste from barrel to barrel. Over the past two decades, Steam
Whistle has grown into one of Canada’s largest and most loved independent breweries. Steam Whistle’s Pilsner is brewed at the historic John Street Roundhouse, near the base of Toronto’s famous CN Tower. As a point of note, Steam Whistle is one
of the only remaining Pilsners in the world that still adheres to the strict
portable. Steam Whistle’s specially designed cart also features a variable frequency drive (VFD) to help optimise energy efficiency even further. At Steam Whistle, the pump is used to
transfer viscous yeast from multiple tanks located around the brewery as and when required. This activity has been in progress for the past 18 months and offers improvements over the use of diaphragm pumps. For instance, the air consumption associated with diaphragm pumps is avoided, lowering energy consumption and cost. In addition, smooth, low shear pumping is assured, while cleaning and maintenance is easier.
standards of the Bavarian Purity Act of 1516. There is no corn syrup, no foam enhancers and no artificial preservatives; the company brews using only pure spring water, malted barley, hops and yeast. There are certain challenges associated
with the pumping of yeast. For instance, pumps should be low-shear types to prevent possible yeast damage. Here, MasoSine pumps supplied by WMFTG are proven to be very effective, and one such pump is in use at Steam Whistle. The three-vessel Esau & Hueber brew
house on site offers a rate of 125 hl @ 12.0°P for wort treatment, water balance and CIP. Designed and engineered in accordance with ULc, CSA and TSSA-CRN regulations, the technology is deployed to ensure optimum wort quality and efficiency. Supplied as part of the brew house
package, the MasoSine Certa 100 was seen as being useful for yeast transfer duties in other parts of the Steam Whistle brewery. With support from WMFTG Canada and senior sales engineer Fabio Martino, the Certa 100 is now fully

HIGH VISCOSITY, LOW SHEAR MasoSine Certa pumps are purpose- designed for low shear, superior viscous product handling with virtually no pulsation. Unlike traditional pumps with rotors that cut through the fluid, Certa’s sinusoidal rotor gently carries fluid through the pump to reduce shear, while reducing power consumption by up to 50% when transferring high viscosity substances such as yeast. Ideal for the food and beverage sector, Certa pumps offer EHEDG Type EL Class I and 3A aseptic certification as standard. The Certa 100 is the smallest in a range of seven pumps that offers flow rates to 99,000 l/h and pressures to 15 bar. Such has been the success of the Certa
100 for yeast transfer that viability assessments are currently in progress for another application at Steam Whistle. Elsewhere at the company, a long-
serving Bredel hose pump is part of a diatomaceous earth (DE) process, a filtration technology used for clarifying beer. DE can be highly abrasive, for which Bredel hose pumps are suited.
