DEVICE AND METHOD FOR MEASURING A DENSITY OF PROVIDED GRANULAR MATTER

摘要

A device and a method for providing granular matter 103 is described, wherein the device comprises a receiving container 101 configured and adjusted for receiving the granular matter. The receiving container has an output 104 for providing the granular matter to a further processing and the device comprises a measuring unit 102 configured for measuring a density of the granular matter in the receiving container using terahertz (THz) spectroscopy. The density of the granular matter may be measured while the granular matter is moving through the outlet of the container at consecutive time intervals or continuously. The measuring unit 102 may comprise one or more THz generating units 106, one or more radiating units 107, and may be coupled to a calibration unit 108, and a data processing unit 109. The measuring unit may be placed on the outside of the receiving container.
