Cleaning Pattern, The Golden Section
The patented Golden Section cleaning pattern (EP-Patent No.: 0495883. US-Patent No.: 5,279.675) is
unique in building up the pattern in an ultimate uniform way. The pattern starts very coarse and refines
itself in a step-less way by laying out the tracks approximately in the middle between the two most
distant tracks already made. This means that the jets always clean the areas containing most
remaining product, and thereby remove as much deposit as possible in the shortest possible way.
In case a complete cleaning pattern is not required, it will be possible to reach the same cleaning level
within half the time and by using half the amount of cleaning fluid compared to a traditional step-wise
cleaning pattern. Furthermore, due to the uniform cleaning pattern, the cleaning can be stopped at any
time, whereas with traditional non-uniform cleaning pattern this would not be advantageous. However,
after the complete cleaning pattern has been established, the difference between the Golden Section
and the traditional stepwise cleaning pattern is negligible.
