Pneumatic Conveying

IEDCO has been providing pneumatic conveying solutions for since 1995 and has established a solid reputation within many industries based on our expertise in pneumatic conveying technology. Our pneumatic conveying systems are custom designed to specifically suit a wide range of duties and have set new benchmarks in relation to efficiency, quality, and cost-performance ratio. IEDCO Pneumatic Conveying Systems (IEDCOveyors) transport the most diverse materials, including: powders, pigments, granules, tablets, capsules, small parts, etc.

  • Reliable Low-Weight Systems
  • Low Maintenance & Easily Cleaned
  • Simple Installation & Control
  • cGMP & Hygienic Design
  • Quiet & Reliable Operation

Dense Phase Pneumatic Conveying

dense phasePneumatic Conveying has been given a “bad rap” when handling fragile products due to the fact that many have tried a version of it only to erode (or even explode) their product through a high velocity conveying line. These experiences are, in fact, representative of conventional dilute phase vacuum conveying. With dilute phase conveying there is a lot of air used for conveying and therefore a lot of product interaction (potential damage) at the high velocities necessary for conveying with traditional vacuum pumps.

Our pneumatically operated vacuum pump makes Dense Phase pneumatic conveying possible. By being able to pull nearly a full vacuum (27” Hg.), the vacuum pump permits us to let in very little air for conveying. The product can be pulled through the line in dense slugs which move at low velocity, with little to no product interaction. The result is the ability to vacuum transfer fragile products without damage. This opens up the door to automation, efficiency, labor savings, and solutions to many ergonomic issues that plague the food, chemical, and pharmaceutical industries.

Case Study

Pneumatic conveyors and  vacuum feed wand holders were used to transfer dry food materials from Gaylords to various process systems. Using dense phase conveying and a large flapper valve as the discharge feeder, we were able to transfer the different and delicate products without damage.
