Carbo Controller CCR
Founders Brewing Co. had clearly defined its investment objective: The brewery was looking for a more accurate, reproducible, less labour-intensive and not least faster solution than the static tank process to adjust the CO2 content of its beers. In addition, carbonization should take place "inline" - with the highest accuracy even at the large volume flows that occur during beer clarification using a separator. The brewery sold its diatomaceous earth filter in 2001. Since then, all beers have been clarified only centrifugally.
Consequently, Founders opted for an inline carbonator type Carbo Controller CCR. The function-tested module delivered to the USA comprises a CO2 dispensing block, the individually designed static mixers, pressure control valves and the measuring and control instruments for fully automatic control and dispensing of the CO2 between separator and filling line. All functional units are pre-wired on a common tubular frame including control unit and lines. Accordingly, the Carbo Controller was quickly integrated into the production process at Founders and put into operation.
Since its commissioning, the Carbo Controller has been working to the brewery's complete satisfaction. It currently carbonates over ten different types of beer. Founders uses the Carbo Controller only for carbonization. The controller then dispenses the CO2 into the beer stream according to this specification. The Carbo Controller injects the CO2 at the entrance of the solution section. The CO2 is then finely distributed and dissolved using static mixers designed for the specific process conditions. In addition to controlling the carbonization process, the O2 content in the end product can also be monitored inline to ensure product quality.
"As brewers, we want CO2 to be dissolved as completely as possible so that nothing is wasted. The Pentair carbonator is our perfect solution to this challenge," summarizes Jeremy Kosmicki, master brewer at Founders. Visible sign of this satisfaction: Just three years later, Founders Brewing Co. ordered a second Carbo Controller from Pentair.
