Description
Oxygen in beer or soft drinks
affects the preservability and the taste. Therefore, it is important to use an
optimally deaerated water for the production of soft drinks and the redilution
of beer. GEA offers a 2-stage water deaerating system which achieves an
excellent value of residual oxygen and is thus especially suitable for these
and some further applications.
Special Features:
- Low residual oxygen content
- Low operating expenses
- Low CO2 consumption
- No sealing water consumption
- Assembled ready to work, i.e. low assembly costs
- Deliverable for wide range of flow rates
- Option: Control of the residual oxygen
In the first stage (B1) the largest part of oxygen is extracted by pure
vacuum deaeration. Being mixed with CO2, the predeaerated water is carried into
the second stage (B2). CO2 increases the release of oxygen. The CO2-oxygen
mixture is also sucked off by the aid of the vacuum pump 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 vacuum is generated by means of a dry-running rotary piston
pump. The operating expenses are considerably reduced due to the fact that no
sealing water is required. Detectors for pressure (PIA), level (LA), and
possibly oxygen (QIA) monitor the system for its proper function.
The
system is cleaned via the product path. In addition, an optimum cleaning effect
is obtained by the spray balls in the deaerating tanks.
