Abstract
A Vacuum conveying apparatus with a weighing and metering device, comprises a separation container (), acted on by a vacuum, for intermittent intermediate storage of material conveyed in a suction gas flow, a force isolation means for entry of conveyed material into the separation container (working side), a weighing device () for, in particular, continuous weighing of the separation container, as well as a vacuum pump () and a controller. In order to create a vacuum conveying apparatus that can guarantee a more precise weighing and/or a more accurate stipulation of the timepoint for turning off the vacuum pump or for interrupting the suction process during the ongoing conveyance process, the vacuum pump () is isolated in terms of force from the separation container () and is also situated such that it is not weighed.
