BrauKon VitaSius
Yeast degassing – Hygienic vitalization of the harvest yeast
for a higher yeast vitality
After the fermentation process is the harvest yeast highly stressed because
of the adverse physiological alcohol and carbon dioxide content in the beer.
These unfavorable conditions are mostly kept in the yeast storage tank,
resulting in a slow recovery and a weak startup of the next fermentation.
Even in former times brewers knew about this correlation regarding to the
yeast vitality and its effect on flavor stability of beer.
Due to this the harvest yeast was degassed before storage by the so-called
“yeast washing” by using a yeast sieve.
With the BrauKon VitaSius the yeast is hygienically and gently released from
carbon dioxide “inline” during the harvest.
This degassing is carried out in a hygienic, easy to clean in-line apparatus,
which is fully integrated in the pipe cleaning process.
Through the large sight glass the degassing process and harvest yeast
is visible.
Sterile air as carrier gas is gently added to the yeast before the degassing.
The yeast is applied to the central pipe by an inlet distributor.
On this occasion, the yeast is expanded by surface enlargement and carbon
dioxide is emitted which is taken away from the surplus sterile air.
The sterile air is consciously added without a mixing nozzle to avoid an
excessive aeration of the yeast.
The degassed yeast is transferred by a frequency-controlled pump to the
yeast cellar.
The VitaSius is fully integrated into the CIP of the yeast harvest pipe and
requires no further cleaning steps.
Advantages at a glance:
•• Considerable higher yeast vitality
•• Fresh and pleasant taste of beer
•• Possibility to reduce the yeast cells for pitching
•• Less dead cells in the harvest yeast
•• Significant degassing of carbon dioxide
•• Biological safety because of “Hygienic-Design”
•• Simple and safe inline cleaning
