Caribou Jumps to Chain-Vey

Caribou Coffee, the well known Minnesota-based coffee chain, installed cable tube conveyors in their roastery several years ago. Their first cable system transported green coffee from an unloading point to their classification equipment. The cable conveyor manufacturer had promised longevity. However roastery managers became largely dissatisfied upon experiencing a much higher cost of ownership and maintenance than promised over time.

CARIBOU’S NEEDS

Green coffee is typically abrasive and for this reason wears conveyors more quickly than other applications. Roastery managers were replacing cable and pucks on a 18 to 24 month basis due to cable stretching. Cable fraying also meant having to splice sections of cable periodically. Plus, if the cable broke in the middle of production, managers did not want to splice cable with orders unfulfilled. They wanted to try a Chain-Vey system and see if it truly meant less maintenance and greater reliability.

MPE’S SOLUTION

MPE engineers offered a cost effective Cable-to-Chain-Vey Retrofit for their green coffee cable conveyor. It would capture nearly all of the benefits of Chain-Vey without needing to replace the entire conveyor. It could also be done in half the time it takes to install a new conveyor.

RESULTS

The retrofit installation was a breeze and completed in half a day. Roastery managers were impressed on the first production run by reduced noise coming from the conveyor. As time went on though, the most important benefit has been the peace of mind in the system’s reliability. The chain will never fray and never break.

“Never have to worry about it. It’s quieter than the cable system. Pretty much a set it and go piece of equipment.”

-Adam Sislo, Engineering Supervisor, Caribou Coffee
