In addition to air filtration and dedusting products, Freudenberg also offers the dairy industry engineering services including control and regulation systems, including planning, production, design and installation. The most recent example: the TPU 500 tank overpressure system.
Milk and dairy products are often stored for days in tanks or silos before being processed further. During storage and emptying, it must be reliably prevented that raw milk, intermediate or end products come into contact with unfiltered outside air and that unwanted microorganisms penetrate in this way. The TPU 500 tank overpressure system solves this problem. The basic principle is as simple as it is sophisticated in detail: the system creates a blanket of air above the milk that is free of bacteria, yeasts and moulds; a slight overpressure in this blanket of air ensures that no outside air can penetrate, not even when the tanks are emptied.
Last but not least - and completely independent of World Milk Day - a quick note for vegans who avoid animal milk products: Freudenberg's tank overpressure system protects so-called milk substitutes, i.e. vegetable drinks based on soy, oats or almonds, from contamination just as reliably as animal milk.
