Fill Pass Diverter (Scale Diverter) Handling Coffee Beans

Published: November 1, 2016

Customer: A Regional Coffee Producer

Material: Roasted Coffee Beans

Product: Roasted Coffee Beans

Applications:  Pneumatically convey roasted coffee beans via a closed loop system into individual product bins for packaging.

Challenge: Locate a valve that will divert the conveyed material into the individual bins with minimal damage to the beans.


System engineers working with this project initially compared a Vortex Fill Pass Diverter to a flapper style scale valve. Upon conclusion of the comparative tests between the two types of valves, the group discovered that the Vortex Fill Pass Diverter caused minimal damage to the roasted beans – much less than the flapper style diverter.

After further review, the engineers proposed an adaption to the Fill Pass that might further reduce damage to the beans. Instead of tangentially conveying the beans into the hopper stack, they suggested replacing the fill stack with a curved discharge tube to introduce beans directly into the bin.

Vortex manufactured four Fill Pass Diverter Valves, model D53-8SSSF-MG-P10-X, with flanged radius discharge elbows. The special design improved the overall bean condition.
