This bulk bag unloader system conditions and discharges various semi free-flowing, hygroscopic, contaminable powders at a rate of 8000 lb/hr, while feeding the powders to the end-of-line container filling system. The operation’s increased production requirements dictate greater frequency of line changeovers to accommodate processing of other types of powdered materials and filling of multiple consumer packaged goods (CPG) container sizes. This process-specific, NBE bulk bag unloader and container filling system was designed based on the particular changeover and throughput specifications of the application. Changeover times were reduced as a result of design features, such as: the elimination of internal angles, corners, and dead spaces to reduce accumulation of contaminants; angled planes, rounded-radius framework, highly finished plate, and stand-offs to speed moisture run-off away from product contact areas; and subassembly access, removal, and replacement as single-operator, tool-less actions to reduce time and labor per event. Despite the process demands requiring more frequent changeovers, total line uptime and throughput performance increased due to reductions in the time-per-changeover event. Process throughput was further increased due to the effective in-line conditioning of the multiple material types. Container fill rates reached beyond the target of 15 containers per minute -- rates unattainable by the previous system.
