12.3. CLEANING THE SCRAPER SYSTEM
The scraper system must be cleaned after every use. In addition, it might be
necessary to clean or change the scraper system even between two passes.
This prevents mixing of the fine parts of the raw product and the already
dispersed product.
1. Dismount the scraper knife.
2. Use a spray-moistened lint-free towel to clean the individual components of
the scraper system thoroughly.
3. Mount the scraper knife.
Make sure that the scraper knife fits correctly to its lateral stop.
When using a new knife, the scraper base must be adjusted
again (see chapter 10.7 Aligning the scraper socket in parallel to
the roller)
12.4. TEMPERATURE CONTROL OF THE ROLLERS
If the rollers are temperature-controlled, the machine must be temperature-
controller for a while before adjusting the rollers.

NOTE
Danger of destroying components
If the machine is adjusted before the temperature control, the adjustment

machine. Danger of damaging or destroying the rollers.
