Solid Cake Formation - Bauer S300 Original Operating Manual

NOTE The reaction time before each setting change takes several minutes, meaning that the
effect of any change can only be determined after this time.
For this reason, always allow enough time after making a change and only make
changes in small steps!
NOTE
Before the initial startup and after prolonged downtime, the separator should be flooded
before switching it on by starting the pump briefly in order to prevent possible damage
from dry running.

7.2 SOLID CAKE FORMATION

Fig. 7-3 Cake formation aid
To place the cake formation aid, check before beginning work that the switch cabinet is disconnected
from the electrical supply and is not energized.
Then do as follows:
1. Remove the 2 weights from the arms of the output regulator in order to open the regulator flaps,
then secure the flaps.
2. Insert the starter cake in the form of the cake formation aid made of foam rubber.
3. Place one weight in each middle position on the output regulator arms. The pressure flaps of the
output regulator must rest against the starter cake such that pressure is applied to the cake when
the separator is started up. As a suitable solid cake is formed, the output regulator arms will slowly
move upwards.
The pump can then be switched on without pauses

If no solid cake is present in the discharge area, it must be
ensured that the discharge flaps rest fully against the
mouthpiece.
After switching on the separator, start the pump only briefly -
for about 1 to 2 seconds, just long enough for the supply line
and separator to be filled. Then wait until liquid phase no
longer runs out and repeat the process.
Depending on the pumped medium, a solid cake will begin to
form after about 5 repetitions and push the cap away from
the mouthpiece.
Alternatively an artificial cake can be created.
To do this, place the cake formation aid made of foam rub-
ber, included in the standard equipment, behind the flaps.
This starter cake is replaced as the separation process con-
tinues by a newly formed solid cake made of the separated
medium, pressing out the starter cake. A starter cake should
be employed when the solid cake has been removed from
the machine for cleaning, inspection or maintenance pur-
poses. If the machine is not operated for a prolonged period
of time such that the cake has either hardened, frozen or
become very soft, a starter cake is also required to restart
the separator.
