RECOVERY MACHINE AND RECOVERY METHOD WITH A VERSIBLE PRESSURED PRODUCT

摘要

The invention relates to a filling machine (1) comprising: at least one filling valve (8) configured to be connected to a respective receptacle (2) to be filled and selectively available between an opening configuration, in which the filling valve (8) feeds a pourable product to the receptacle (2) at a pressure higher than the atmospheric pressure, and a closing configuration in which the filling valve (8) interrupts the flow of the pourable product to the receptacle (2); and a decompression circuit (33) configured to depressurize the receptacle (2) after filling and comprising in turn a decompression chamber (35), a decompression duct (34) connected both to the receptacle (2) and to the a decompression chamber (35), and a flow control valve (39) arranged in series on the decompression duct (34); the filling machine (1) further comprises pressure control means (42, 43, 44) configured to keep the pressure inside the decompression chamber (35) at a predetermined pressure value (P 0 ) higher than the atmospheric pressure (Pa).
