Leading American Brewery Saves 3.2 Million Gallons of Water Per Year with Gamajet


A major U.S. brewery needed to automate tank cleaning in large horizontal fermentation tanks to increase production and reduce costs. The initial method combined manual entry and three tank cleaning machines on portable carts. The carts were hooked in series and fed through the manway on the front of the tanks. The procedure took close to two hours. The manual entry and physical requirements made tank cleaning lengthy, cumbersome and dangerous.


A project was started to evaluate the cost versus benefit of permanently mounting two Gamajet 4 machines suspended from the ceiling of each fermenter. By choosing dual nozzle units with larger orifices instead of triple nozzle units with smaller orifices, the flow per cleaning jet was drastically increased. This additional impact allowed the brewery to use two cleaning heads instead of three.


The increased impact and jet throw length provided excellent cleaning performance at a 33% reduction of flow rate. The total cleaning time was reduced from two hours to less than 30 minutes. Since the cleaning process was automated, personnel could be used in more productive tasks. By decreasing the cleaning times, the brewery could produce more product using existing equipment. Estimated water savings are 3.2 million gallons per year.
