Abstract

The invention relates to a method for emptying the residue from a container. According to said method, once the bulk of the container has been emptied, the container is closed in a gas-tight manner and the gas in the container vibrates by pressure due to periodical mechanical variation of the gas volume. The generation of the pressure vibration is maintained at least until the fine-particle solid materials adhering to the wall of the container are vibrated by resonance, and fall under the effect of gravity. The frequency of the pressure vibration is between 10 and 200 1/s and correlates with the amplitude in such a way that an average pressure difference of between 10 and 2000 mbar is created in the container. The inventive device comprises a system for producing a periodical axial movement that is axially applied to a gas-tight axially elastic element, e.g. a membrane or bellows, which can be arranged on an opening of the container in a gas-tight manner.
