In Two Stages to a Minimum Value of Residual Oxygen
Oxygen in beer or soft drinks affects the preservability and the taste. Therefore, it is important to use optimally deaerated water for the production of soft drinks and the adjustment of original wort or alcohol content, respectively.
GEA Diessel 2-stage water deaerating system, type DIOX-2™, achieves an excellent value of residual oxygen and is thus especially suitable for these and some further applications.
In the first stage the largest part of oxygen is extracted by pure vacuum deaeration. Being mixed with CO2, the predeaerated water is carried into the second stage. CO2 increases the release of oxygen. The CO2-oxygen mixture is also sucked off by the aid of the vacuum pump (P3) via tank B1 in the reverse flow direction of the spray jet, thus increasing the deaerating effect of the first stage. By a discharge pump (P2) the deaerated water is carried to the consumer.
The sealing water consumption is minimized by the integrated temperature control. Detectors for pressure, level, and possibly oxygen monitor the system for its proper function.
The system is cleaned via the product path.
