It is important that nip gap and scraper gap are coordinated.
The product film should have an even width on all rollers and an
even thickness per roller.
The setting ratio from gap 1 to gap 2 should not exceed the value
of approx. 8:1 because else a product jam upstream of gap 2 can
arise and the product is pushed outward (see 12.8.3 Optimum
product flow)
In general, good results can be achieved with a
gap ratio
gap 1
: gap 2
of approx.
3:1.
15.
Take up the product with the spatula and supply it back to gap 1 (nip
gap).
›
To remove the product from the scraper system, use a separate
spatula so that the finely grates product is not contaminated with
raw product.
