发明名称 Vacuum-assisted bulk particulate packaging system
摘要 A system for forming particulate material in a bulk form comprises a compression tower having a top and sides depending therefrom. A compression chamber having side walls and an open bottom is reciprocatively mounted to said tower for deposit of loose particulate material therein. The system further includes a first conveyor assembly displaced from said tower. In its extended position, the chamber contacts the first conveyor assembly and the bottom of the chamber is closed thereby. A vacuum blower draws loose particulate material into the chamber through an inlet and compresses it against the first conveyor assembly. A ram assembly within the chamber further compresses the loose material into a bulk form atop the conveyor belt. When the chamber and ram assembly are returned to their retracted positions, the material bulk is transferred downstream by the first conveyor assembly to a space between vertically spaced second and third conveyor assemblies. The downstream end of the third conveyor assembly pivots toward the downstream end of the second conveyor assembly as the material bulk is urged therebetween such that the material bulk is again compressed between the downstream ends.
