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.
