It opens automatically at low pre-pressure and closes automatically when the pressure reverses: The new Evoguard check valve does not only work reliably, it is also hygienic and robust, making it ideal for use in the food, beverage and dairy industries. Thereby, the Evoguard check valve ensures maximum process reliability without any external actuation.

Technical highlights:
- Low relief pressure
- Very low flow resistance
- Max. product pressure: 10 bar
- Materials: EPDM, FKM, HNBR | stainless steel 1.4404, optional 1.4539 & 2.4605
- Compatible with small flanges DN25–DN150 & OD1.0–OD6.0

There are several ways to produce non-alcoholic beer. The most common methods include preventing the formation of alcohol, which, however, requires subsequent pasteurisation due to the high residual extract or the use of an energy- and water-intensive dealcoholisation plant. A further approach is the use of so-called crabtree-negative yeasts.

Under aerobic conditions, these yeasts stop alcohol production and generate aromatic substances, but no alcohol. To enable the yeast to work in an aerobic, i.e. oxygen-rich environment, constant aeration of the tank is necessary. Poseidon provides for exactly these perfect production conditions. The tried-and-tested unit for dynamic fermentation now comes in a version with integrated aeration and an oxygen sensor to create a permanently aerobic environment in the fermentation tank.
The process unifies various advantages: On the one hand, operation requires little effort, while at the same time the short process duration of less than four days enables high line availability. On the other hand, the unit can be retrofitted into almost all cylindroconical tanks, not only are the investment costs low, but so are the running costs, as Poseidon scores highly with its minimal energy and media consumption.

If you want to learn more about Poseidon, crabtree-negative yeasts and 0.0 volume percentage beers, the drinktec is the perfect opportunity. As the Steinecker team is, of course, represented at the Krones stand in hall B6 and is looking forward to your visit. Take advantage of this opportunity and make a personal appointment now for one of the five days of the exhibition.
