3 Dimensional accuracy during forming
3.1 Tolerable dimensional deviations during
shaping forming due to different doughs:
Our Janssen forming rollers are engraved precisely
according to drawing.
However, the biscuits produced with these Janssen
forming rollers may show dimensional differences due to
the individual dough properties (ingredients, temperature,
liquid content, sticking, swelling and baking behaviour).
Since Janssen has no influence on these dimensional
deviations, which can be caused by the dough
properties, they are outside our area of responsibility
and are therefore not the subject of complaints.
subject of complaints.
3.2 Tolerance range
The biscuits are cut off after forming. This cutting process
causes the biscuits to be slightly compressed. This
compression is compensated for during the production of
the roller by stretching the engraving in the forming roller.
Nevertheless,
dimensional deviations
can still occur.
Depending on the quality of the dough, they vary within a
tolerance range.:
In forming direction:
approx. +5% / -20%
Transverse to the forming direction:
about +/-5%
Pastry thickness:
about +/-10%
