Principle of a vertically adjustable, ring- or disc-shaped distribution of the feed medium in CIP processes (Fig.: Joachim Löw)
Joachim Löw
Optimised CIP
Vertically adjustable, ring-shaped or disc-shaped (horizontally
aligned) distribution of the feed medium (CIP medium,
fresh water, etc.) results in significant advantages in cleaning
compared to conventional systems (spray nozzles). Above all,
the consumption of electrical energy (less pumping power
required in the supply and return lines in terms of quantity
and pressure) and thermal energy (through more targeted
heating of the surfaces that come into contact with the
product to be cleaned and not so much of the air volume)
is reduced. In addition, there is less product loss and waste
water pollution in combination with automated tank rinsing,
cleaning times are shortened due to faster and more accurate
phase changes as well as higher cleaning efficiency with
oscillating liquid flow.
The "disc-shaped" distribution of the liquids by means of a
plate or a corresponding horizontal distributor has advantages:
1. all the liquid that hits the tank wall in a ring shape can
run down from there over the entire tank wall. The amount
of liquid, which with nozzles only comes together in the
lower, cylindrical area, is here already easily adjustable in
the upper area. A ring-shaped distribution of liquids for tank
cleaning requires significantly less volume flow for the same
cleaning effect.

2. new medium washes off the "old" liquid much more
consistently from top to bottom. Liquid flows that fall directly
downwards and thus virtually "overtake" adhesions of
older media in the upper area do not occur. The separation
between the phases takes place with less mixing. 3.
3. product residues are flushed "linearly" from top to
bottom into any remaining product with little water. The
tank wall can be kept clean with little dilution of the product,
drying of product is prevented.
Due to the changed distribution of the medium, the air volume
is heated up or cooled down later and less. The heat energy
exchanges much more directly with the stainless steel;
i.e. where it is also important.
4. The vertically variable mobility of the "distribution
plate" increases the advantages of the system even more:
The "distribution pattern" of the medium is no longer always
the same, but can change. This means that the liquid
on the tank wall no longer necessarily runs off at a constant
speed within a phase, but can be changed by changing the
emergence plane (vertically) several times. With the same
cleaning effect, the volume flow can be lowered or the effective
time reduced.
Since the vertical adjustment is carried out specifically via the
automation, the functions such as time, position, frequency,
etc. can be adapted to the cleaning of each tank.
