Breakthrough in Automated Retort Loading - 50 Percent Increased Throughput for Small Cans

Jun 21, 2011

One pet food company automatically loads into a retort basket 3,000 212 X 107 sized cans per minute, up from 2,000.

Covington, LA - Allpax Products, a division of ProMach and a market leader in retort technology and retort room automation, announced today the successful development of the fastest retort basket loading system in the world - in excess of 10 sweeps per minute and basket changeover in less than 20 seconds.

"Food and pet food processors can potentially add a filler line and the new 400X Hyper-Loader and significantly boost throughput," said Greg Jacob, vice president and general manager, Allpax. "The productivity improvements should more than outweigh the capital investment for a solid ROI."

The Hyper-Loader technology of more than 10 sweeps per minute, up from 6 to 7 for a standard Allpax automated loader, and a reduction of basket changeover time from 30 seconds to less than 20 came out of an application where a pet food processor upgraded its kitchen. With the upgrade came more cans per minute than the automated loader could handle. The Allpax solution raised the throughput of 212 X 107 sized cans from 2,000 to 3,000 per minute, a 50 percent increase.

The Allpax Hyper-Loader technology breakthrough is based in part on:

  • Servo carriage control for precise and fast positioning
  • Container pattern pre-stage area to allow for continuous sweeping
  • A Slip sheet squaring area to ensure accurate placement
  • A VFD control on all conveyor motors to optimize efficiency and flexibility
  • A smart hydraulic product elevator for precision placement
  • Proportional hydraulic valve control to optimize elevator positioning speeds
  • Flexibility to run multiple container sizes rapidly with easily installed change parts

At only four feet longer than a standard Allpax automated loader, the Hyper-Loader offers essentially the same footprint and should present few issues in retrofit applications.
