After every use I brush of the underneath with paint brush and then
use compress air to blow out any flour accumulated inside the grinding
head and the motor compartment.

I would not do this. Use compress air to clean all hard-to-get spots.

The grinding head rotates with high velocity and "blows" flour inside the
collecting
plastic pan. The vent is there to let air transfered in to the pan with
flour escape outside.

It is a separating cup. It separates flour from air using centrifugal forces
and lets air to pass to
the vent. That is why more flour dust is expelled from the vent when the cup
is getting filled up
with flour.
That all makes sense. I do indeed notice that when the cup is removed
a lot more flour blows out of the vent.
In fact, though, the cup hardly fills with flour at all.
Many thanks.
