6.1.2 MAINTENANCE OF AGITATOR AND
GASKETS
The agitator blades are equipped with scraping pads
made of atoxic plastic materials suitable for food
industry. These components are subject to wear
according to the characteristics of the employed
mixture: with high sugar content and low fat
percentage a remarkable wear of pads can be the
detected.
When the clearance between the pads and the
cylinder is excessive, the agitator is no more able to
perfectly scrap the cooling cylinder walls resulting in
an extention of batch freezing times. To restore the machine performance, it is sufficient to
replace the scraping pads.
6.1.3 REFRIGERATING UNIT
In case of machine provided with air condenser, it is necessary to periodically clean the
condenser fins from the dirtiness sucked in by the fan motor, which can obstruct it and
considerably reduce its efficiency.
To clean the condenser, make use of a brush or an exhauster.
