ABSTRACT:
An air treatment plant for food is closed with the exception of an inlet and an outlet opening (3). In the plant, a pressure increase needed for circulating the treatment air tends to produce an air flow in one direction (29) through an inlet or outlet tunnel (20) communicating with the inlet or the outlet opening. The tunnel (20) has an upper wall (21) in which are arranged nozzles (22) directed substantially opposite to said direction (29), and a lower wall (23) formed with openings (24) for evacuating the excess air in the tunnel (20) produced by air jets (30) generated by a fan (27) and emanating from nozzles (22). A method for reducing the air flow in the inlet or outlet tunnel thus comprises the steps of directing a plurality of air jets (30) from the upper boundary surface (21) of the tunnel (20) substantially opposite to said direction (29), and evacuating from the tunnel the excess air produced by the air jets through openings (24) in the lower boundary surface (23) of the tunnel.
