ABSTRACT:
A weighing apparatus having a plurality of removable ingredient retention and discharge hoppers supported on a frame, each hopper having an integral screw conveyor and each being removable for replacement by another hopper. The screw has a structure to inhibit discharge squirting. Discharge of the ingredients is through a sealed connection to a weighing hopper. This weighing hopper has an enclosure housing and is formed of a pair of flexible webs which extend downwardly and are shiftable between a closed retention condition with lower edges adjacent each other and an open discharge condition with the lower edges spaced from each other. These lower edges are secured to the inner edges of underlying pivotal support pans, such pans being pivotal to shift the webs and to engage the webs to invert them for assured full discharge of the contents.
