It took the Donaldson Co. two years, 40 scientists and millions to build a better mouse trap — or a microbe trap, to be exact — for beverage and yogurt manufacturers.
The Bloomington-based filtration giant — known for devices that purify air, steam and gases inside factories — recently threw its filtration expertise into the world of consumable liquids for the first time.
The result is LifeTec, an ultrafiltration cartridge that captures microbes, bacteria and particles from beverages. Officials cut the ribbon on a new manufacturing plant in Haan, Germany, last week that will make the product and said it could result in big changes in the market.
LifeTec liquid filters capture dust, bacteria and the cryptosporidium and giardia parasites that could sicken humans and cripple most food makers if the microscopic pests accidentally squirmed into a product.
The food industry depends on filters and uses them vigorously to protect its products and reputations. Food producers came to Donaldson to help them develop liquid filters that were stronger, that didn't break and that could be changed less often.
Two years ago, Donaldson started working with customers such as Coca-Cola, Nestlé, Dannon, Molson Coors-Romania and 20 other companies. Many of the firms, now beta testing the new liquid filters, already knew Donaldson as a maker of air filtration equipment that inflates shrunken soda and water bottle "preforms" into three-dimensional bottles using blasts of sterilized air.
Others knew Donaldson for its ability to make and insert a pocket of sterile air between each cup of yogurt and its lid. Others relied on the company to purify the air in clean rooms and factories.
That familiarity with the company is why they turned to Donaldson for the better liquid filter.
