National Bulk Equipment sanitary bulk bag unloader with CPG container filling system

National Bulk Equipment has developed a bulk bag unloader system which conditions and discharges various semi-free-flowing, hygroscopic, contaminable powders at a rate of 3.6 t/h, while feeding the powders to the end-of-line container filling system.

This process-specific, NBE bulk bag unloader and container filling system is designed based on the particular changeover and throughput specifications of the application. According to the company, changeover times are 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 labour per event.

The enclosed bulk bag discharging, material conditioning, feeding and filling systems protect operators by preventing migrant material dusts from entering the process area as well as protecting process material from contamination.

The complete process sequence, including bulk bag loading and conditioning, material size reduction, feeding and package filling, operates on paired, process-specific structural framework chassis with all automation and control functions centralised to a single, menu-driven HMI to enable standardised and system-wide data reporting.

The bulk bag unloader and container filling system is built based on HACCP assessments that guide the determination of the framework and component materials of construction.
