15.6 INNER TUBE EXTENSION
If the FAN press screw separator was equipped
with an optional mouth piece extension or with an
optional housing spacer ring, the inner tube of
the screw will have to be equipped with a so-
called inner tube extension as well.
This extension is put onto the inner tube of the
screw in the pressing zone in order to adapt the
screw length to the prolonged pressing zone.
15.7 RINSING DEVICE
On option, the FAN press screw separator can be equipped with a rinsing device.
Such a device is mainly used for separation of sewage water in slaughterhouses.
A jetting lance corresponding to the length of screen and/or of housing is installed between the screen
basket and the housing. Thus the screen can be flushed at intervals with hot water under pressure.
The flushing intervals are to be adjusted according to demand.
This device helps to keep the screen permanently clean during operation and during standstill it avoids
a jamming of the screen with the cooled fat.
