Product recovery system reduces material loss
National Bulk Equipment’s ProductSaver line of wet packaged product recovery systems ensure the controlled removal from the package of free-flowing--or flow-resistant--wet contents, and the complete separation of the contents from the packaging material, reclaiming packaged wet contents for proper handling, and recovering packaging material for recycling.
ProductSaver quickly makes significant contribution to process performance by: providing tangible metrics tor sustainability improvements; protecting product safety; reducing material loss; and keeping labor on-task. Engineered to integrate with legacy processing and packaging operations, the system can also be designed to run as a self-contained wet material reclamation system. The ProductSaver system combines package infeed, package opening, and contents and package separation processes into a single-stream product recovery sequence. Whether pallet loads, cases, or single packs, no break-pack or razor knife steps are necessary; protecting personnel from knives and repetitive motion injury. Package opening occurs within the compression screw press where precision-formed, specially pitched, 304-2b stainless steel screw flights draw packages from the infeed chute into the compression sequence. The screw flights are edge-finished to open packages and accelerate material release prior to compression action. The conical screw shaft, together with an end block press, creates a progressive compression force on the pre-opened packages to ensure thorough release of contents and separation of contents from packaging material.Two large-bore pneumatic cylinders power two compactor gates for final-stage material release. Automated discharge of compacted packaging material is provided by sensors at the compactor gates that gradually release compactor pressure and open the gates to discharge recovered packaging. ProductSaver product recovery systems provide up to 99.95% of content recovery for most wet material, according to NBE. ProductSaver systems are designed and built to the particular requirements of each application, regardless of package material or shape, including: ampoules; gabletop, coated paperboard cartons; polypropylene dairy containers; aluminum cans; aseptic cartons; PET bottles; ploy-based tubes; roll stock packs; and foil laminate pouches. The process-specific design and materials of construction of ProductSaver systems helps ensure optimal compliance contribution (OCC). ProductSaver systems are also built to meet the FDA, cGMP definition for cleanability and are immediately able to assist in improving FSMA readiness.
