Patent ID: 7264192

Claim:
A particulate matter vibro-fluidizing apparatus comprising vibrating means and means for treating the particulate matter, said vibrating means providing a vibrating motion in a substantially vertical direction, said means for treating the particulate matter comprising a set of different types of vibrating bodies operating in cooperation with said vibrating means, said vibrating bodies comprising a container having a generally flat horizontal bottom, said container being filled with the particulate matter defining a particulate matter layer, and a vibrating medium installed within the container so that said vibrating medium is at least partially disposed within said particulate matter layer, said vibrating medium being unattached to the container, and said means for treating the particulate matter providing a cooperative vibrating action occurring between said different types of vibrating bodies for controlling vibro-fluidizational behavior of said particulate matter in said particulate matter layer so as to generate circulation in said particulate matter layer by applying vibrations thereto where said particulate matter repeatedly appears at the surface of said particulate matter layer from the bottom of said container.
