Customer:
The Smarties Candy Company was founded in 1949 by Edward Dee. Originally known as CE DE Candy Co., Smarties Candy Co. is the purveyor of the famous hard candy rolls that are enjoyed by millions and are sold worldwide. They have two factories located in Toronto, Canada and Union, New Jersey. The Problem: At their Union NJ facility, Smarties stores dextrose in a 12’ diameter silo and needs to reliably and accurately feed a dilute phase pneumatic conveying line which supplies the manufacturing process. Originally the material packed in the bottom of the silo so it was fitted with air injectors to promote flow from storage to the conveying line. Flow was still erratic and unreliable and frequent manual probing of the silo was required to get the material to discharge.
The Solution:
In 2006, the bottom section of the silo, the compaction zone, was removed and replaced with a 6’ Vibra Screw Bin Discharger. The Bin Discharger is flexibly attached to the bin and vibrated to generate immediate flow on demand. Beneath the Bin Discharger, the company installed a 6” Vibra Screw VersiFeeder to accurately meter the flow from the bin into the pneumatic conveying line. The VersiFeeder employs controlled vibration to maintain uniform material density and to completely fill and empty each flight of the screw.
Results:
Smarties was able to achieve trouble free discharge and feeding to the conveying line at 6000 lbs/hr. The Vibra Screw Bin Discharger/VersiFeeder combination eliminated the need to manually prod the bin and the consistent feed from the VersiFeeder enables the conveying line to work efficiently. The Bin Discharger/VersiFeeder combination has contributed to Smarties ongoing effort to streamline production and maintain the highest standards of quality control in their products. There are currently thousands of Vibra Screw Bin Discharger/ VersiFeeder systems successfully handling a wide range of materials throughout the process industries. Download Case History

With a staff of experienced and talented engineers, technicians and crafts people, Vibra Screw manufactures high quality equipment to store, discharge, meter, convey, size and blend solid materials. The company’s comprehensive product range includes bulk bag unloaders and fillers, volumetric feeders, bin activators, vibrating feeder/conveyors, loss-in-weight feeders, storage pile activators, live bottom bins, live bins, continuous blenders, screeners, controls, and turnkey systems.
This complete line of vibrating tube conveyors moves virtually any bulk material without internal parts to wear or break. The machines are available in capacities up to 300 cu ft/hr, with single unit lengths up to 25 ft. They can be linked together for longer conveying distances and are available in carbon and stainless steel, with finishes to meet virtually any sanitary specification. Optional controls provide a 5:1 feed range and, when connected to a bin activator or bulk bag unloader, feed accuracies of 2-3% are possible for most materials. They also have the ability to handle fragile particles without degradation. A flexible connection at either end makes the machines entirely dust-tight.
Vibra Screw’s AccuFeed uses molded composite components and a modular design to reduce cost and delivery time. Available in capacities up to 600 ft/hr the patented AccuFeed employs controlled vibration to achieve volumetric accuracies of ± 1-2 %. The machines disassemble quickly for cleaning and meet FDA and USDA sanitary requirements. The company stocks popular sizes for immediate delivery. AccuFeeds may be scale mounted for batch or continuous weigh feeding applications.
With a broad product line that addresses everything from main silo discharge to micro-ingredient feeding, Vibra Screw offers a continuous or batching weighing solution for every dry bulk feeding problem.Accurate weighing of dry bulk solids requires reliable and consistent flow of material from storage into the feed mechanism itself. Vibra Screw’s unique use of controlled vibration promotes flow, uniformly densifies the material, and completely fills and empties each flight of the feed screw. As a result, all Vibra Screw weigh feeding systems start as highly accurate volumetric feeders, eliminating inaccuracy during the refill cycle.Vibra Screw offers weigh feeders in screw sizes from 1/4″ to 18″ along with a broad range of belt, pan and tube feeder based systems.
A line of dependable economical Bin Dischargers is available to system suppliers and OEM’s from Vibra Screw Inc. Based on over 50 years of bin discharge experience, those units are ruggedly built, simple to install and come with Vibra Screw’s unconditional performance guarantee.The Bin Discharger’s simple, compact design incorporates all of the important features customers have come to expect from Vibra Screw such as a leak proof molded sleeve, heavy duty suspension system, and long life vibrator. Designed to provide on demand flow from bins up to 20′ in diameter, standard Vibra Screw Bin Dischargers are available for quick delivery in both carbon steel and stainless steel.
Vibra Screw’s exclusive ASME dished head Bin Activators are designed for severe duty service on large silos. The dished head/ lower cone construction provides a compound slope profile that safely handles large head loads while preventing compaction at the outlet, a problem with single slope dischargers.Avaiable in diameters up to 18 feet, the Bin Activators are equipped with Vibra Screw’s patented oil lubricated gyrator for extended service life.
The product of over 50 years experience building feeders, conveyors and Bin Activators for severe duty applications. Vibra Screw’s Flexifeeder line of flexible screw conveyors offers an expanded capability with less frequent maintenance. As with all Vibra Screw products, each Flexifeeder is matched to the individual customer requirement using both the company’s extensive installation data base and complimentary lab testing. The use of controlled vibration at the inlet hopper, eliminates material packing and tunneling and encourages more even loading of the conveying screw. This, along with a simple robust drive system, results in a more uniform repeatable conveying rate and dramatically reduced maintenance. Flexifeeders are available at capacities up to 1500 ft3/hr and single unit conveying lengths of 50′. Flexifeeders can be teamed with Vibra Screw Bulk Bag Unloaders and Vibrated Bins to provide integrated solids handling.
