ABSTRACT:
A method and apparatus for densifying a flexible bulk container with dry or semi-moist flowable material broadly includes a method and apparatus whereby the container and its contents are relatively gradually lifted and then relatively rapidly dropped onto a stop member such as an impact anvil, serving to densify the material contents of the container, or by alternatively compressing the contents thereof for maximum concentration of the container's contents. The apparatus broadly includes a frame which is positioned on top of a load cell or other weighing apparatus, a container supporting member such as a deck, and an impact member such as a post which serves to isolate the load cell from the impact of the container on the impact member. The filling apparatus is constructed whereby the contents of the container may be weighed during densification thereof so that the container may be rapidly and accurately filled without the need to remove it for weighing or to interrupt the densification process. In addition, the apparatus hereof is configured to compress the contents of the container whereby the material contents in the upper portion of the container will be satisfactorily densified. The invention also includes methods for densifying the material, for continuous weighing of the container during densification and for further densification of the material contents by compressing the container within the frame.
