A suction head for cleaning of the surface of carcass parts consists of an oblong handle ( 1 ) and a nozzle ( 3 ) mounted at one end of the handle. An air duct ( 6 ) passes through the handle and the nozzle, and it can be connected with a suction device via a coupling ( 5 ) in the other end of the handle. Steam ducts ( 10 ) are designed in the nozzle ( 3 ) to lead hot steam to the surface parts ( 11 ) of the nozzle, which are intended to get into contact with the surface of the carcass parts. These steam ducts ( 10 ) are connected with a supply duct ( 7 ), which is connected with a steam source via a coupling ( 8 ) on the suction head. The supply duct ( 7 ) for steam passes through the handle ( 1 ) from its coupling end to the suction device and to its nozzle end. In the nozzle the duct passes into the steam ducts ( 10 ). It is less fatiguing for an operator to use this suction head than a conventional head with disinfection facility.
