Freudenberg Filtration’s TPU 500 tank pressure system ensures germ-free environment for liquid foodstuffs

Freudenberg TPU 500

Freudenberg Filtration Technologies’ TPU 500 is designed to prevent contamination from liquid foodstuffs during storage and filling.

Whether it is milk or milk-based liquids, cream, raw fruit juices, vegan soy drinks, liquid eggs or sugar-free soft drinks, minimizing the risk of processing such sensitive foods requires the high levels of hygiene. Silos and tanks in which liquid foods are temporarily stored prior to further processing or filling can be a gateway for bacteria, yeasts and fungal spores. One potential source of contamination is impure air entering the tanks through open vents, for example.

The TPU 500 tank pressure system from Freudenberg Filtration Technologies  keeps germs and harmful particles away from the valuable liquid foodstuffs. The TPU 500 system creates a germ-free air blanket above the liquid raw, intermediate and end products. Gentle overpressure in this air blanket ensures that no impure outside air can come into contact with the food – even when emptying the tanks and silos. Incidentally, Freudenberg’s hygiene protection system works just as reliably in filling plants in the food and beverage industry.

Roughly the height of a person, the modular structure consists of fully welded stainless steel housing sections connected by locking latches. Each unit can be customized to meet the customer’s specific onsite specifications and requirements. The modular design of the system makes it easy and safe to change the air filters. The continuous volume flow of the system is regulated fully automatically. The TPU 500 unit continuously monitors the change in pressure and indicates necessary filter changes to operators in good time. This ensures optimized production processes and results in the food manufacturing industry.

Freudenberg Filtration Technologies offers food manufacturing and processing companies a wide range of filtration materials and filter models in liquid and air filtration as well as dust removal technology. This product portfolio is further enhanced by a comprehensive range of consulting and other services, including engineering all-in-one solutions. The new TPU 500 tank pressure unit is one example of a fully integrated system from a single supplier.
