Dearation to perfection
For process plants for various applications, GEA TDS provides deaerator
systems which are tailored exactly to requirements – an essential building
block for achieving the best product quality.
The reduction of gas during the thermal
heating process is the prerequisite for
obtaining a long-lasting production
cycle. The effective reduction of oxygen
in the solution plays a decisive role for
the quality of the product. A GEA TDS
deaerator system effectively prevents
oxidation and foam formation. Ideal
results are achieved by reducing unwanted
flavouring and odorant substances. The
combined and integrated aroma recovery
process minimizes aroma loss during
deaeration.
The deaerator system effectively frees reconstituted solutions
or products mixed with powdery substances from air brought
in during the mixing process. Fluid aroma substances can be
removed and condensed in an external cooler and returned to
the product flow. The deaerator system, including the external
cooler, can be fully integrated into the automatic thermal
process, for instance into a UHT plant. CIP cleaning of the
deaerator system is also performed automatically.
Gentle to the product: a mushroomshaped
product distributor for products
containing solid particles
Viscous liquids with chunky particles are
gently deaerated without vacuum support
in a special buffer tank, the thermaldynamic
layer storage tank.
The product enters the tank from the bottom and is applied
evenly and uniformly to the previous product surface in very
thin layers by a mushroom-shaped product distributor. The
layers of product are vertically stable, i.e. they do not mix with
each other, so that the product that is filled in first also leaves
the deaerator first. To ensure that the product flows gently and
smoothly into the tank, the product distributor is flexibly mounted
on the product supply pipe, so that the static height can be varied.

Advantage: adjustable cascade valve for the product inlet
A special, adjustable cascade valve for the product inlet provides
a very effective product surface in the deaeration vessel. The
valve thus helps to achieve an optimal deaeration result.
