Technology Review

Moisture/Solids/Ash Analyzer
The Computrac MAX 5000 provides accurate results for moisture, solids, and ash in just a few minutes. Because the analyzer is chemical- and glass-free, materials can be tested at any location in your facility without worrying about contamination. The instrument is easy to use, allowing even the most inexperienced operators to produce consistent results. It is suitable for use on the production floor or in the lab. The precision balance, large selection of ending criteria, and statistical-analysis features make it a powerful tool for research and development.

Particulate Sensor
The PMS particulate sensor requires minimal maintenance and employs a field-proven combination of passive-induction and protected-probe technologies. As particles flow near and around the probe, minute currents are dynamically induced into the probe by flowing particulate. A DSP processes the signal into an absolute output that is reasonably linear to mass. Protective layers over the probe work in combination with induction sensors to ensure reliable operation with all types of particulate, including moist powders and highly conductive dusts. Maintenance is minimal and there is no need for an air purge. For durability, the sensors are passive and free of electronics. The sensor is designed to be used with the DPM particle monitor in order to be intrinsically safe.

Bin Activators
Pulsonic bin activators clear bins, hoppers, and other mass-flow vessels of compacted solids. Materials are removed from channels, ducts, or recesses. The units introduce multiple instantaneous sonic airbursts into compacted material to restore flow without the shock and vibration methods that can damage equipment.

Guided-Wave Radar Continuous-Level Measurement System
The Flexar guided-wave radar continuous-level measurement system successfully measures cement and flyash in silos ranging from 30 to more than 65 ft in height. Unlike other continuous-level measurement technologies, guided-wave radar is unaffected by dusty environments such as what occurs during the filling of silos with cement and flyash. The Flexar unit uses time-domain reflectometry (TDR) technology to make accurate measurements. With TDR, microwave pulses are guided to the material surface along a continuous stainless-steel cable of 0.31 in. diam. The microwave pulses reflect off the material surface and the time of flight results in the distance measurement of empty space. The unit calculates the material level based on your silo height information and transmits this data either through smart RS-485 communications for use with the SiloTrack inventory management system or via a 4–20-mA output signal to a remote receiving device such as a control system or digital display meter.

Sortation Subsystem
The UniSort MXT sortation subsystem is available for the company’s vhswEDGE central merge. The patent-pending UniSort MXT software enables the vhswEDGE to maximize product density on the infeed line to the sorter, enabling throughputs of up to 400 cartons/min with high-speed sliding-shoe and linear-belt sortation systems. The vhswEDGE is a combination of conveyors configured to facilitate high-speed induction onto a main conveyor line from picking operations in a distribution or manufacturing facility. The addition of UniSort MXT software optimizes the lane-releasing prioritization schemes of the vhswEDGE to control product flow, reduce gaps, and create a steady stream of product inducted into the sorter.

Manual Dump to Rigid-Bin Weigh-Batching System
This manual dump to rigid-bin weigh-batching system eliminates dust during manual dumping from bags, boxes, drums, and other containers, delumps the material, and feeds it gravimetrically from mezzanine level into rigid bins placed on a floor scale. The dump station features a high-velocity vacuum fan that draws airborne dust from the operator’s atmosphere into two cartridge filters. Automatic reverse-pulse filter cleaning allows continuous, efficient operation; timer-activated solenoid valves release short blasts of compressed plant air inside cartridge filters, causing dust build-up on the outer filter surfaces to fall into the hopper. Filters are accessed easily by removing the interior baffle, and they are replaced rapidly using quick-disconnect fittings.

Open-Construction Weigh-Belt Feeder
This sanitary, stainless-steel gravimetric weigh-belt feeder utilizes the same conveyor components and weighing system as the standard Model 970, but it comes with a self-supporting stand and eliminates the enclosure. Available belt widths are 12, 20, and 24 in. The Model 970N requires less physical space to install and allows hard-to-feed products to be laid directly on the belt. The unit has been used to feed chopped potatoes, fruits/nuts, pet food, lettuce, cereal, sugar, flour, and other food products. Eliminating the enclosure also makes the feeder a good fit for chemical applications.
