摘要： There is described a packaging apparatus (1) for forming a plurality of sealed packages (2) from a tube (3) of a web of packaging material (4) which is continuously filled with a pourable product. The packaging apparatus comprises a delimiting element (37) arranged, in use, within the tube (3) and being designed to divide the tube (3), in use, into a first space (38) and a second space (39). The packaging apparatus (1) also comprises a sterile gas supply device (43) for pressurizing the isolation chamber and the second space (39) by means of a respectively a first flow of sterile gas and a second flow of sterile gas.

摘要： There is described a packaging apparatus (1) for forming a plurality of sealed packages (2) from a tube (3) of a web of packaging material (4) which is continuously filled with a pourable product. The packaging apparatus comprises an isolation chamber (10) separating an inner environment (11) containing a sterile gas from an outer environment (12). The packaging apparatus further comprises a delimiting element (48) arranged, in use, within the tube (3) and being designed to divide the tube (3), in use, into a first space (49) and a second space (50). The packaging apparatus (1) also comprises a pressurizing device (47) for pressurizing the second space (50) by means of a pressurized sterile gas. The delimiting element (48) is arranged within the isolation chamber (10).

摘要： A method (400) for controlling a regulating valve (206) of a packaging machine (100), wherein the packaging machine (100) is a roll-fed packaging machine configured to receive a roll of a carton-based packaging material (102). The packaging machine (100) is configured to be connected to a processing line (202) via the regulating valve (206), wherein the processing line (202) is configured to feed a liquid food product (216) to the packaging machine (100) through the regulating valve (206). The method (400) comprises determining (S402) a product flow, using a flow meter (106), of the liquid food product in the packaging machine (100); determining (S404) an inlet pressure measurement (306), using a pressure sensor (204), of the liquid food product in the packaging machine (100); and making use of the inlet pressure measurement to the packaging machine (100) for adjusting the regulating valve (206), said regulating valve being configured to receive an output signal from a flow feed forward module (308) in combination with an output signal from a flow proportional-integral-derivative (PID) module (310), wherein the flow feed forward module (308) has the inlet pressure measurement (306) and a flow set point as input signals, and wherein the flow PID module (310) has the product flow and the flow set point as input signals.
