Brewhouse modernisation job for tradition-steeped brewery
Brewhouse modernisation job for tradition-steeped brewery. At the Wadworth Brewery, in Devizes near Bath, as part of a brewhouse modernisation job, new energy-saving technology has been installed for an output of 225 hl/ cast-out quantity. The brewery produces around 110,000 hectolitres of ale a year, and is committed to using traditional production processes. A corporate philosophy given visual form in the brewhouse modernisation concept, since to highlight the brewery’s traditional virtues Krones encased the visible stainless steel sidewalls in oak panelling.
- Buffer tank before the wort copper
- Wort copper with Stromboli internal boiler
The keywords for the Stromboli internal boiling system are defined forced-flow function, low evaporation values and the ultra-gentle thermal treatment of the wort. This results in low resource consumption and longer cleaning intervals. For wort circulation, no thermal energy at all is required, since a pump recirculates the copper’s entire contents several times an hour. The flow inside the Stromboli boiler is exceptionally homogeneous, and independent of the temperature involved. This means the wort is heated up very quickly, and the flow profile inside the boiler materialises immediately. Once the wort is boiling, the boiler power can be reduced. The choice of the Stromboli was influenced not least by the energy economies involved. The previous system evaporated around ten per cent of the water into the atmosphere. With the Stromboli, the evaporation rate is reduced to less than four per cent, without altering the flavourings in the beer. Additional energy is saved by recovering the heat in the vapour condenser for producing hot water. - Whirlpool
Krones’ whirlpool concept offers several advantages: fast separation of the hot break, an optimised hot-water balance, and swift removal of the wort combine to ensure clean, clear worts. - Wort cooler with plate heat exchanger: on the product side, the wort is cooled down here from approx. 100°C to approx. 20 °C, with the water being cooled by cold water at 10°C, that in the heat exchange process is warmed up to approx. 80°. The hot water is re-used for pre-mashing.
