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 10 tanks. See flow sketch on reverse. On
tank no. 1 to 8 on the flow sketch, you will find the SCANDI
BREW® pneumatic sample valves that are mounted on the
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 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.
When taking a sample there are two possibilities; either sterile or
non-sterile sampling. For sterile sampling of the chosen tank,
the “sterile” button is pressed and the pipeline to the sampling
panel will be steam sterilised. After sterilising, the pipeline is
blown dry with sterile air or CO2. Now the “sampling” button can
be pressed and the sample media will flow from the chosen
tank to the sample coil at the sample panel. By pressing the
“flush” button, the pipeline is hereafter flushed with water,
steamed and blown dry.
When choosing non-sterile sampling for non-microbiological
samples the first step after choosing the tank, is to press the
“sampling” button. The sampling process will then be the same
as above but without the sterilisation before the sample is taken.
• Fully automatic 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
• Simultaneous sampling and or CIP
The sample valves and pipelines with other valves are CIP’ed
together with the tank. The cleaning process is started by
pressing the “CIP” button or by signal from a PLC and runs
automatically according to the pre-selected time.
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 utility box near the tanks and
the sample valves to the sampling panel.
The sample valves on the tanks are to be inspected every
2 years and gaskets are replaced. 6 mm valves and fittings
on the sampling panel are checked with regular intervals and
gaskets are replaced.
• Extra sample module for sampling from up to 20 tanks
• 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
