Water Deaerating Systems
Oxygen in beer or other beverages can impair both shelf life and taste. For this reason, optimum degassing of the water used for beverage production and redilution of beer is of enormous importance for product quality. With the help of hot degassing, GEA VARIDOX-H water degassing system achieves very low residual oxygen levels, making it suitable for a wide range of applications.
The VARIDOX-H system incorporates sensors for flow rate, filling level and, optionally, oxygen, and these sensors continually monitor key process parameters.
Water at 72 °C is fed into the deaeration column and slowly trickles down the packed columns. The high temperature strongly reduces the solubility of the oxygen in the water. The countercurrent CO2 (N2) ensures an additional release of oxygen.
The plate heat exchanger technology enables approximately 90% heat recovery, by means of a regenerating step, while a subsequent cooling section cools the deaerated water to the desired outlet temperature
VARIDOX CIP is carried out by passing the cleaning solution through the product lines and deaeration column.
GEA has developed the VARIDOX deaeration systems for use by the beverage and brewery industries. For cold deaeration with water temperatures of >10°C we recommend the VARIDOX-C.
The GEA carbonating system type DIMIX-B has been designed for high-precision continuous mixing and carbonation of beer and beer mix beverages.
Supporting small to large feed rates, and configurable for both batch and continuous processes, the dedicated AromaPlus system is built on our reverse osmosis (RO) membrane filtration technology.
The GEA carbonating system type DICAR-B has been designed for continuous high-accuracy carbonation of beer and beer mix and is mainly applied in the brewing industry.
Something caught Farmer Tom's eye. Instead of another product demo, GEA showcased innovations via AR. That's only the start of GEA's interactive digital farm.
GEA scientists are working with researchers at the Graz University of Technology to configure a homogenization process and technology that turns eucalyptus pulp into 3D-printed, organic structures mimicking human veins, arteries and other tissues.
Companies like GEA process and store large amounts of sensitive data. However, security incidents, from ransomware attacks to physical intrusions and industrial espionage, are ever-expanding. GEA’s effective protection of its business partners’ data – as well as its own proprietary information – is evolving into a competitive advantage. We spoke with Iskro Mollov, GEA’s Chief Information Security Officer, about what it takes to protect a global business in a volatile world.
