A centralised sampling system facilitates in many ways
sample taking from beer tanks (in- or out-doors). Because of
the position of the sampling valve on vertical fermenters or
bright beer tanks, access to sampling point often needs
catwalks or platforms. To take a sample outdoor from such
platforms is often done under less favourable climatic
conditions thus giving the possibility of unacceptable samples
as well as increasing the risk of work related accidents.
A centralised sampling system allows for placing the sample
valve at the optimal point for sampling: on the middle of the
cylindrical part of the vessel, independent of whether there is
easy access to this point or not.
The SCANDI BREW® Centralised Sampling System is a
modular system and each section is equipped for taking out
samples from up to 8 or 10 tanks. See flow sketch on
reverse. In the left side of the flow sketch, you will find the
SCANDI BREW® pneumatic sample valves that are mounted
on the tanks.
For mounting the pneumatic sample valve different methods
are foreseen. For new stainless steel tanks the valve is welded
into the tank wall and for existing tanks, the valve can be
supplied with special thread to fit a socket.
Central sample valve and controls
The sampling panel, which is mounted on adjustable legs, is
connected via pipes of Ø10 mm to the pneumatic sample
valves on the tanks. The connections can either be stainless
steel pipes or Teflon hoses, with or without insulation,
depending on local conditions. As can be seen from flow
sketch, the pipe work creates a ring main between the sampling
panel and the sample valve.
When taking a sample there are two possibilities; either sterile
or non-sterile sampling. A sample is taken in the following way:
The swing bend on the sample panel is connected to the
tank from which sampling shall take place.
Thereafter the “start sampling” button is activated and steam
will then run through the ring pipe. The steam sterilises the
pipe and line, the pneumatic sample valve on the tank and
the central sample valve as well.
By activating the ”sampling” button the sample valve on the
The "sampling" button is activated immediately skipping the
sterilisation step. It is now possible, manually to open the
central sample valve and take out the sample.
When sampling has finished the “stop sampling” button is
activated and the operator can now leave the panel. The system
will automatically be flushed with water, sterilised with
steam and blown through with sterile air or CO2.
• Easy and safe sampling from selected tanks
• “Fool proof” operation
• Highly sanitary sampling
• Economic solution compared to “cat-walk” installations
• Optimal sampling point position on tank regardless of tank
construction and access
The sampling valve and ring main for each tank is CIP’ed
together with the tank.
The sampling panel is placed for easy access and handy
operation. However, as straight and simple pipe mains as
possible is recommended. Due to pressure loss the distance
from the panel to the sample valves should be maximum
100 –120 pipe metre.
Services are connected to the underside of the panel and the
sample valves to the top of the sampling panel.
The sample valves on the tanks are to be inspected every 2-3
years and gaskets are replaced. Central sampling valve and
fitting on the panel are checked with regular intervals and
gaskets are replaced.
• Extra sample module for sampling from up to 16 or 20
• Hot water heater (up to 90°C) for hot water sterilisation
instead of using steam
• Feedback signal from sample valve on tank
• More valves on the same tank
