Tank cleaner boosts production by 71%

A food manufacturer was wasting time and money through the inefficient cleaning capabilities of the rotary spray balls used to clean their tanks.

When Gamajet Aseptic impingement tank cleaners were installed, production increased by 71% whilst water and chemical usage went down by 85%.

A rotary spray ball's ability to "clean" is largely dependant on time, temperature and chemicals; a large amount of chemical is required over a longer period of time to compensate for the lack of pressure that the spray ball can exert on the cleaning chemical. The cleaning action results from a sheeting or cascading action of the chemical down the tank walls over a long period of time.

Rotary impingement tank cleaners combine pressure and flow to create high impact cleaning jets. Cleaning occurs at the point where the concentrated stream of water or chemical impacts the surface. This impact, coupled with the tangential force that radiates from that point blasts contaminants from the surface, scouring the tank interior. In conjuction with this impact, rotary impingement tank cleaners are engineered to rotate in a precise, repeatable and reliable, 360 degree pattern. This full-coverage, indexing pattern ensures the tank is cleaned, every time.

The food manufacturer operated four continuous production lines, each with three tanks. When using the rotary spray balls, the tanks were shut down for one hour each day (minimum) to be cleaned. Often the cleaning took longer due to regular clogging of the spray balls. Additional manual cleaning was also required from time to time when the spray balls could not remove built-up residue. The solution was the Gamajet Aseptic VI Impingement Tank Cleaner.

The Gamajet Aseptic VI tank cleaner is designed for permanent installation to provide true germ and bacteria-free cleaning to meet the demands of the food, beverage, pharmaceutical and personal care industries. It's design completely eliminates all areas for potential bacterial growth and it's variable flow rates and consistant 360 degree spray pattern ensure reproducible and repeatable cycles that provide thorough and verifiable cleaning.

A Gamajet Aseptic VI tank cleaner was installed in each of the food manufacturer's three tanks to operate at 115 psi and 15 gpm. Cleaning began with a two minute pre-rinse to remove the bulk of the residue, followed by a five minute recirculated wash with caustic and then a final, two minute rinse. The total cleaning time was 91% faster at only nine minutes, compared with the rotary spray ball.

The design of the Gamajet Aseptic VI coupled with a filtered flow rate allowed for debris to pass through or to be caught, resulting in no clogging. The production facility was able to ulitise the saved cleaning time and increase production by 71%, compared to when rotary spray balls were in use. In addition, the food manufacturer reduced their water and chemical usage by 85% since the introduction of the Gamajet Aseptic VI tank cleaners to their production process. 

The Gamajet Aseptic VI impingement tank cleaner is only available from Spray Nozzle Engineering in Australia and New Zealand.
