ABSTRACT:
An onboard kitchen for an aircraft includes at least one kitchen unit with a counter top, a kitchen sink and a venting hood connected to an air exhaust conduit. A cyclone type separator is connected with its inlet and outlet ports into the exhaust air conduit thus connecting the separator to the venting hood. The cyclone type separator divides the airflow into a clean airflow which is led into a clean air discharge conduit and into a contaminating particles carrying airflow which is led into a discharge pipe connected to a drainage duct which connects the kitchen sink, preferably to a drainage pylon outside the aircraft body. The use of filters is thus avoided and the maintenance costs are minimized.
