Abstract
A method for filling a receptacle (7), which is at least partly gas-permeable with bulk filling material (2), includes subjecting the receptacle (7) at the outer side to an underpressure, in order to generate a feed of filling material through a filling material conduit (4) into the inside of the receptacle (7). The filling procedure is assisted by way of subjecting the filling material conduit (4) to pressure after completion of a first filling time.
Claims20
A method for filling a receptacle, which is at least partly gas-permeable, with bulk filling material, the method comprising the steps of:
- subjecting an outer side of the receptacle to an underpressure, in order to generate a feed of filling material through a filling material conduit into an inside of the receptacle as part of a filling procedure;
- and
- subjecting the filling material conduit to pressure after completion of a first filling time of the filling procedure to assist the filling procedure including the feed of filling material through the filling material conduit, wherein an end of the first filling time is determined by a dropping of a filling speed to a predefined value.
A filling device for filling a receptacle, which is at least partly gas-permeable, with bulk filling material, the filling device comprising:
- a filling material conduit fed from a filling material container;
- an underpressure chamber, wherein the filling material conduit runs out into the underpressure chamber, wherein the underpressure chamber is arranged and configured for receiving the receptacle which is to be filled and the underpressure chamber is configured to subject an outer side of the receptacle, to be filled, to an underpressure, in order to generate a feed of filling material through a filling material conduit into an inside of the receptacle as part of a filling procedure;
- sealing means for sealing the filling material conduit with respect to the receptacle which is to be filled and into which the filling material conduit runs;
- and
- pressure means for subjecting the filling material conduit to pressure, during the filling procedure after completion of a first filling time of the filling procedure, to assist the filling procedure including the feed of filling material through the filling material conduit, wherein an end of the first filling time is determined by a dropping of a filling speed to a predefined value.

- a pressure means for subjecting the filling material conduit to pressure, during the filling procedure after completion of a first filling time of the filling procedure, to assist the filling procedure including the feed of filling material through the filling material conduit;
- and
- a control device configured to at least determine an end of the first filling time based on a filling speed reaching a predefined value.
