The system works in two distinct ways depending on whether the motorised valve is
opened or closed.
2.1. Open valve operation
The rotation of the fan creates a vacuum effect in the local area behind his disk back where
it faces the suction pipe/exhaust 5. When the butterfly valve 7 is open to this effect a
vacuum sucking air flow entering through the pipe 5. Simultaneously the moist air inside
the cooking chamber is induced to leave through the vent tube 6, aided by a flow diverter
(not shown) placed inside the chamber at the exit hole. Through the injector 12 is sprayed
water into the vent pipe - especially at high temperatures - in order to cool and condense
the flow of moist air coming out. The condensate is collected on the bottom of the pipe to
siphon 6 and conveyed through the rubber hose 14.
