PACKAGE,AND METHOD AND DEVICE TO RECOVER ITS CONTENT

摘要

PROBLEM TO BE SOLVED: To enable a recovered material to reuse by separating a mixture of a packaging material and a content in an economical manner. SOLUTION: The device is constituted by a front stage shredder 1; a separator 2 comprising a porous drum and a pressure belt; a pulverizer 3, i.e., a crusher; and a cyclone connected to the crusher 3 by a conduit 4. A packaging material to be processed including contents is thrown into a feeding shoot 1.3 of the front stage shredder 1 and is fed to a cylinder 1.2 of the shredder 1. The packaging material is engaged with a shearing blade to be crushed to rough small pieces and to be cut. At this time, the packaging contents are dropped into a collecting shoot 1.4 with rough granules of the packaging material and subsequently drop into a pulling zone of a separator 2. A mixture of the packaging material and the contents is pulled into between hollow drums 2, 2 and a pressurization belt and receives an pressurizing force. The contents having a flow property are squeezed into the hollow drums 2, 2.
