Abstract
An extraction device for a filter element containing collected particles of target material and an extraction fluid, wherein the device may have a piston and a vibration apparatus for vibrating the filter element to cause particles to move from the filter element and into the extraction fluid. The piston may first create compressed air to urge a first amount of extraction fluid and particles out of the filter element, and may then compress the filter element to urge a second amount of extraction fluid and particles out of the filter element.
