Switching of the annular gap can be achieved with an
adapted, classic valve actuator. More effort had to be invested
in the design of the distribution plate or the distribution cup
and a robust fastening: Different distribution diagrams should
be possible without too much narrowing of the gap surface
(and the pressure). A basic design should be able to be adapted
to as many different tank diameters and flow rates as possible.
The component must be removable from the outside without
Results of the tests are more than pleasing
We assume that the electrical power requirement of the
pumps can be reduced by 35 to 60% even if existing cleaning
targets are converted. Smaller mixing phases and shorter
cleaning times without reducing the effect are also relevant
advantages. For new installations, smaller cable cross-sections
and components can often be used, but replacing existing installations
also pays off.
Another essential benefit of the ring distributor is that in
many companies (e.g. cheese dairies) a defined rinsing of the
tank wall with fresh water without relevant dilution of the
product when emptying in production is possible. Thus, e.g.
in milk and whey tanks, the pre-rinsing can be significantly reduced,
often completely cancelled.
The challenges of development and design, the previous
tests and the optimizations were supported by the HAW University
of Applied Sciences in Hamburg, the Hanover Ahlem
University of Applied Sciences and the Evoguard.
