Bulk Materials Handling Process Integration
Application Case Studies
Bulk Bag Dischargers
This NBE bulk bag discharging system, designed and built specifically for food and pharmaceutical processing and packaging operations, helps ensure compliance with domestic and international sanitary standards. Application-specific construction, including 304-2b stainless steel framework, with continuous weld seams ground to a No. 4 finish, enables CIP sanitizing.

The NBE E3™ bulk bag discharge spout interface protects operators and facilities from exposure to airborne material dusts that can often escape during bulk bag spouting. The NBE E3 closed-cycle dust recovery system secures and encloses the bag spout within a sealed containment cylinder. The sealed cylinder then lowers to elongate the spout and form the bag into a conical shape, aiding in complete material discharge from the bulk bag. The sealed cylinder also works to protect the material, and the total process operation, from the introduction of migrant contaminants.

A multi-national household products conglomerate had an application to introduce a dry powder, methyl cellulose, into a liquid mix tank without agglomerates or fisheyes. Methyl cellulose is a finely divided, extremely hygroscopic powder that has poor flow properties. It is used as a thickening or extending agent.

Bulk Bag Fillers
This NBE, automated bulk bag filling system processes and packages fast, free-flowing, dust-generating material that is static-charged and an explosion hazard. Processed material is transferred from upstream supply to the NBE bulk bag filler station. The physical ergonomic design of the bulk bag fill station helps maintain ideal operator posture for safe, efficient operation.

Container Dischargers
This NBE automated material handling system provides a total process solution for moving highly fragile food product through multiple process operations into bulk storage for temporary holding prior to final packaging. At a process rate of 12,000 pounds per hour, bulk totes of the food product are nested into a lift carriage; the tote is sealed to a custom-designed discharge hood. The tote is vertically conveyed, using 1-1/2 inch, solid 304 stainless steel track and cam rollers, to a 23-foot discharge height.

Mechanical Conveying
NBE mechanical conveying systems for bulk material containers and packaging are critical to the effective transfer of material during production operations. Whether moving material containers into or out of production, conveying containers from process to process, or from processing to packaging, NBE mechanical conveying systems ensure material is moved efficiently and accurately.
