Hose Pumps Improve Quality at Brewery
- Quality threatened at one of Europe’s most productive breweries
- Dissolved oxygen levels of less than 10 parts per billion required
- Hose pump success leads to further installations
The ROLEC DH units utilize the Ampco SBI pump to recirculate a fermenter and simultaneously induce hop pellets dry into the stream of beer. The pellets are held in a pressurized chamber, which is purged of air using carbon dioxide (CO2). Pellets can be induced into fermenting, finished, or crashed beer. The shear pump creates a differential pressure for induction of the pellets from the hop vessel. The pellets are chopped to just the right size so they can settle during the dry hop holding period.
