 Tank top systems  


Conditioning and mixing of yeast in storage tanks obtaining a
homogeneous slurry with uniform temperature and consistency.
Optional facility to aerate or acid wash through propeller

The mixer comprises gear motor, combined gear console/CIP
entry, CIP pipe with spray ball penetrated by the hollow mixer
shaft ending in propellers with CIP nozzles.
For shaft lengths above 1.5 meters a sanitary tripod support
is welded into the tank bottom. This support is fully cleaned
by the bottom CIP facility.
During cleaning there are no CIP shadow areas caused by
the propeller shaft or propeller blades as these parts are integrated
in the cleaning.


Stainless steel AISI 316 (standard).
All other parts in contact with product
are non-toxic foodgrade.
propeller speed: 45 - 75 rpm
(or acc. to customer specification)
Power supply: 380 V, 50 Hz (standard)
CIP supply: Capacity and inlet pressure:
For mixers with aeration facility:
20 m3 at 3 bar (44 psi)
For mixers without aeration facility:
20 m3 at 2 bar (29 psi)

Optimal mixing efficiency is obtained by interval agitation. In
order to minimize damage of the yeast cells, the agitation
should normally be restricted to the cooling period and prior
to pitching.

If equipped with the optional aeration valve, it is possible to
aerate through the CIP nozzles when agitating. Due to the
efficient agitation, this facility may also be employed for pH
lowering through acid washing.
Please observe that the mixer must never run dry i.e. without
yeast or CIP liquid.



• Integrated cleaning of mixer with no CIP shadow areas
• Individual mixer design as per tank details
• Propeller blade designed for optimal mixing
• Low rotation speed ensuring careful and non-destructive
treatment of the yeast slurry
• Increased vitality of the yeast cells by aeration
• Acid washing through propeller nozzles
• Improved cooling-efficiency

The SCANDI BREW® top-entry mixer is mounted either as a
separate part on the tank top or alternatively as an integrated
part of the top plate.
At the tank bottom the mixer shaft is supported by a bottom
console welded onto the tank cone. For smaller tanks a special
version of the yeast mixer can be mounted without
bottom console.
Detailed mounting instructions and installation tools for levelling
of bottom console are required for correct mounting.

Hot cleaning is recommended. During cleaning the main part
of liquid is lead through the CIP-pipe to the spray ball while a
smaller amount is lead through the hollow shaft to the spraying
nozzles below the propeller blades and at the shaft end.
The shaft is cleaned outside from a slot in the spray ball bearing.
In this way a proper cleaning of the mixer shaft in- and
outside as well as the propeller and the bottom console is
The mixer should always run during CIP. If required, the
arrangement is steam sterilisable as well, during this procedure
the mixer should stand still.

Periodic check of bottom bearing can take place by controlling
length of red detector pin (Pos. 10) as per separate
Replace mechanical seal if leakage is detected from the
drainage channel of the gear console.
Visual check of the spray ball is recommended.
