NBE Bulk Bag Discharger

Wednesday, 12 July, 2017 | Supplied by: Mercer Stainless Ltd


National Bulk Equipment's Bulk Bag Discharger with integrated clean-In-place (CIP) features is designed to speed changeover during sanitary process operations.

The process-specific bulk bag unloader with chain-style tubular drag conveyor is engineered and built to withstand rigorous duty cycles and stringent process demands. Process requirements include a target material infeed rate of up to 13 t/h and frequent changeovers that demand system-wide cleaning to microbiologically safe levels.

The bulk bag discharger uses two integrated hydraulic massage paddles, each with 997 kg of paddle pressure, to condition the material and aid material flow. The material flows through the NBE E3 enclosed bag spout interface where the closed-cycle dust collection system filters migrant material generated during bag unloading and reintroduces the material back into the process flow. The E3 also works during bulk bag unloading to elongate the bulk bag, further ensuring complete material discharge.

Changeover times are reduced as a result of sanitary design features, including the elimination of internal angles, corners and dead spaces to reduce accumulation of contaminants as well as angled planes, rounded-radius framework, a 32 Ra finish plate and stand-offs to speed moisture run-off away from product contact areas. Subassembly access, removal and replacement is engineered to be completed as a single-operator, tool-less action that reduces time and labour per event.

The chain-style tubular drag conveyor minimises product breakage and degradation while providing a dust- and airtight material transfer method. Integrated CIP capabilities are provided by an automated CIP cart which enables a complete washing and drying procedure and aids in meeting regulatory requirements for food-grade system design.
