Verena Street Coffee is a specialty roaster in Dubuque, Iowa. They recently moved into a 34,000 square foot facility and needed help building three new post-roast processing systems.
VERENA’S NEEDS:
Each system needed flexibility for employees handling multiple blends, batch sizes, grinds, flavors, etc. Additionally, Verena’s owners needed systems that could scale with projected growth without the need of replacing conveyors and equipment that had yet to make a return on investment. Verena took full advantage of its situation in building a new operation from scratch; consulting with MPE engineers in judiciously laying out each system to ensure ease of transport of totes, safe worker movement, and the facility’s overall aesthetic appeal to white-label customers. Additional engineering considerations like broad sweeps of the tubular conveyor elbows and extra outlets (for grinders and totes) ensured operational longevity of each system at full speed and capacity.
MPE’S SOLUTION:
Flavoring system: Taking totes of roasted coffee, transferring to a blender for flavoring, then transferring back to totes
Grinding system: Transferring coffee from totes to a grinder and then back to totes
Blending system: Taking totes of fresh roasted coffee, batching specified quantities for blending, then moving blends to totes
FLAVORING SYSTEM
On the floor-level is a Chain-Vey tubular drag conveyor inlet where totes can be wheeled up to and emptied. The conveyor transports the coffee upwards to the mezzanine where the mixer is. After flavoring, the coffee will drop vertically through the mezzanine floor into another tote (yet to be installed in these photos).The perspective atop of the mezzanine looking at the flavoring mixer. Note the Chain-Vey above has two outlets, yet only one mixer to empty into. Eventually Verena will add a second mixer without needing to modify the tubular conveyor system.
GRINDING SYSTEM
The grinding system begins with a floor-level tube conveyor inlet where totes of coffee are emptied. The coffee is conveyed upwards using a 4″ diameter Chain-Vey to a mezzanine where batch bins reside as intermediary storage to regulate the flow of coffee into the 600 FX grinder below. After the coffee is ground and densified, a 3″ Chain-Vey conveys the coffee upwards to another batch bin for intermediate storage until it’s ready for transport.For aesthetic and workflow reasons Verena wanted the grinder and Chain-Vey to sit in-line with each other. MPE placed the Chain-Vey’s turnaround inside the grinder’s footprint to achieve this.In another example of planning ahead, a second batch bin located atop of the grinder system’s mezzanine is ready for eventual installation of a second grinder and Chain-Vey.
BLENDING SYSTEM
This is a wide shot of the blending system; on the left are three floor scales and unloading inlets for wheeling up and emptying totes of coffee; on the right is a blender and corresponding outlet for finished batches.The floor scales are robust enough to handle sizable steel totes but also precise enough to measure specific losses-in-weight consistently for desired coffee blends. The scales send these measurements to the fully programmable and automated PLC which starts and stops the feeders according to the program recipe.This blender sits on load cells to measure weights of incoming and outgoing coffee; data which is then transmitted to the PLC. This second weight measurement affords redundancy in the blending process and allows for easier process management.
RESULTS:
Verena Street Coffee now has a showroom-quality facility with three MPE-engineered systems. Together, Verena has the flexibility and operational efficiency that fits with their current business needs while fully prepared for future growth. Their white-label business is especially poised to benefit from this easily expandable capacity. The reliable conveyance Verena Street Coffee enjoys with their Chain-Veys, the unsurpassed grinding quality with their MPE grinder, and the expertise MPE engineers leveraged from hundreds of past systems integrations coalesce into Verena having one of the most prized roasteries in the Midwest.
CHICAGO, IL — Are you the owner of a bulk solids conveyor grappling with frequent breakdowns and extended maintenance times? The solutions you’ve been waiting for are here! Chain-Vey, the world’s leading tubular drag conveyor, is now available in a complete quick-ship system or cable retrofit in only a matter of days! Our customers often tell us they love the technology but at times can’t afford the long wait times, sometimes up to three months, for a new Chain-Vey system.
A large flour processor installed Chain-Vey tubular drag conveyors inside their process system for their reliability, ease of product changeover, and product non-sifting capability.
