6.1.2MAINTENANCE 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.
