Plant-Wide Weigh Batching System
This automated plant-wide weigh batching system simultaneously weighs up to seven major ingredients received in bulk bags and unlimited minor ingredients received in 50-lb sacks, pails, or boxes, and conveys weighed batches to a downstream blender. Components include: five loss-of-weight Bulk-Out bulk bag dischargers with large surge hoppers and rotary airlock valves; two loss-of-weight Bulk-Out bulk bag dischargers with small surge hoppers and flexible screw conveyors; two loss-of-weight bag dump stations with flexible screw conveyors; a check-weighing hopper; a Twin-Centerpost bulk bag filler; a Pneumati-con dilute-phase pneumatic conveying system including blower, filter receiver, and conveying lines; and a programmable controls package. Weighed ingredients are conveyed pneumatically to a filter receiver that discharges the batch into a mezzanine-level, high capacity blender mounted on load cells, providing confirmation of final batch weight. Blended batches are gravity discharged into a paper sack filling machine or a bulk bag filler. Flexicon Corp., Bethlehem, PA 888-353-9426 www.flexicon.com

Container/Bulk Bag Densifier with Scale System
This new system is designed to automatically fill containers or bulk bags by weight, and settle the contents. Sanitary type 304 stainless steel construction with continuous TIG welds and no tube penetrations allow for quick, thorough wash-down cleaning. Compact, low-profile design is ideal for applications with limited headroom or floor space. An operator simply selects a recipe from the control panel and presses a single button to initiate the fill cycle. The batch controller sends signals to start the product in-feed system, activates the high amplitude densification system, and stops the fill system as required based upon the programmed set point. NTEP-approved weigh modules are protected by a floor-mounted stainless steel machine guard. Material Transfer & Storage, Allegan, MI 800-836-7068 www.materialtransfer.com

Continuous Weigh Feeders
Better-Weigh continuous feeders are ideal for gravimetric feeding of dry bulk materials where it is necessary to determine actual feed rates on a loss-of-weight basis. Available in seven models with feed rates from 1 to 550 cu ft/hr (larger sizes available), these feeders are designed to provide feeding in either batch or continuous mode depending upon the arrangement of the feeder’s control electronics. In batch mode, the batch controller is used to control the fast (bulk) and slow (dribble) speeds of the feeder. Accuracies of ±0.5% can be easily achieved in 2-lb or less batches, and ±0.25% with 3-lb or greater batches with time spans of 30 to 90 seconds. In continuous mode, the feeder’s electronic controller is used to constantly monitor loss of weight of material per time in order to maintain a continuous loss of weight with an accuracy of ±0.25% to 0.50%. Standard features include a platform or lever balance scale, sealed tactile keyboard, 7-digit numerical keyboard, automatic manual batching, and a 2- or 5-cu-ft hopper. Sanitary construction is also available. Metalfab Inc., Vernon, NJ 800-764-2999 www.metalfabinc.com

Batch Automation
PRO Series batch automation allows formulas to be manually or electronically entered into the system, and the control system will automatically make sure that the proper amount of ingredients are measured into each scale and that the material is transferred to the mixing operation where the proper mixing cycle is handled including mix time and transfer of ingredients to packaging or bulk load out. PRO Series blend automation allows formulas to be manually or electronically entered into the system, and the control system will automatically make sure that the proper ratio of liquid and dry ingredients are proportioned and blended into a homogeneous mixture.

Weigh System for Bulk Bag Filling
NTEP-certified weigh systems are now integral elements of the design and manufacture of NBE bulk bag filling equipment. As an original design component, the systems eliminate the variable weight outcomes and resulting material waste or re-filling that may occur with bolt-on load cell or third-party NTEP scale systems. The systems also aid in supporting weigh accuracy validation in regulated processes and practices, such as cGMP. Material weights are measured to an accuracy of +/-.01%, up to a total filled bag weight of 4500 lb. National Bulk Equipment Inc., Holland, MI 616-399-2220 www.nbe-inc.com

Blending Scale
The E955 blending scale is designed to weigh and blend two different free-flowing or semi-free-flowing products into the same bag with a split reaching up to 90-100%. It consists of a main weighing hopper fed by a gravity-vibratory feeder and an auxiliary weighing hopper fed by a vibratory feeder. The two products are blended in the main weighing hopper and top-up is done to accurately reach the final target weight. High hygienic standards are achieved, with contact parts in SS304. Simplex and duplex configurations are available, reaching up to 18 BPM (simplex configuration) and 36 BPM (duplex configuration).
