Global Specialty Coffee Expo 2017 & Interpack 2017; a momentous lineup

Mar '17

Modern Process Equipment (MPE) is excited for a momentous lineup of shows this year; most notably Interpack 2017 and Global Specialty Coffee Expo 2017 (check for a complete listing).

For over 60 years, MPE has built the finest array of commercial and industrial coffee grinders in the world. This year is no exception in the level of innovation MPE brings to the industry. The IMD.2 800 Series grinder makes its worldwide debut at Interpack 2017; the first of its kind to implement independent drive motors for each roll. Users can electronically customize each roll’s speed to achieve a range of ratios from 1:1 to 1:4. The IMD.2 800 Series’ automated recipe-driven control system with precision servo gap control allows for micro fine adjustments in 10-micron increments. This heightened precision in gap control coupled with individually adjustable roller speeds is beneficial for espresso pod and capsule applications; effectively engineering a perfect, repeatable grind. Genuine thru-roller water-cooling ensures a continuous flow of cool water through all rolls and bearings, keeping them cool. This stabilizes tolerances and ensures perfect parallel operation—even during periods of extended operation. MPE will also bring its 3” Chain-Vey system, built for unsurpassed preservation of coffee aromatics during conveyance. Its gas-tight design and nitrogen-purge capabilities are great for Turkish coffee, pod, and capsule makers. For an up-close demonstration at Interpack 2017 visit booth A04 in Hall 2.

The MPE booth at Global Specialty Coffee Expo 2017 will feature the GPX.WCI and SRM 4555 coffee grinders along with MPE’s 3” Chain-Vey system. The versatile water-cooled GPX.WCI stands beautifully with its stainless steel hopper and black, blue, and polished steel exterior. Capable of grinding between 50 microns (ultrafine) to as large as 1000 microns (coarse filter), it is the staple of many startup roasters. The more robust SRM 4555 grinder is the perfect fit for those making their first foray into the world of accurate, higher-capacity roller-style grinding. MPE’s booth number at the Global Specialty Coffee Expo is 1010.

Verena Street’s Showroom-Quality Process System

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

Tube conveyor system inside Verena's coffee facility
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)

Grinding System

Grinding system at Verena coffee facility
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
Floor weight scales and load cells measure loss in weight of coffee from totes
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


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.

Philz’ MPE-Designed Coffee Processing System Featured on ABC7 News

When our friends at Philz Coffee told us their amazing new MPE-designed processing system—with its shiny new green coffee silos, classification system, Chain-Vey tube conveyors, roasters, and packaging system—was going to be featured on ABC 7 News, we knew it was because Philz is obviously an incredible roaster doing something special in the coffee world. But it’s nice to see our own work play a part in Philz’ story and success as one of the US’ fastest growing roasters.

Roast Magazine Feature

MPE’s president Dan Ephraim extended his advice in Roast Magazine’s January/February 2017 issue in the first of a two part article “Building a Mid- to Large-Scale Specialty Coffee Roasting Plant.”

This advice echoed by Ephraim, who recommends clients start with a “5,000-foot view” of the overall project, allowing them to “develop an order of magnitude on the kind of space and resources necessary to move forward.”

Ephraim also suggests having the latest design resources available, such as 3D modeling, to “eliminate issues down the installation road.” He adds that someone on your team needs extensive experience with the software to make the best use of these tools.

MPE’s Grinders & Chain-Vey Featured on Unwrapped 2.0

We are very happy when the work of our customer Green Mountain Coffee is featured on a TV show as fun and exciting as Unwrapped 2.0; but we’re especially proud when the work of our engineering, sales, and manufacturing teams is featured so prominently as well. And in case you were wondering, those are 5″ Chain-Veys (featured at 0:45 and 1:15) and IMD-999 grinders (at 2:25) inside Green Mountain’s roastery.

Give us a call if you think our grinders and Chain-Vey tubular drag conveyors might be able to do wonders for you too.

Willy Wonka of Coffee

For most customers our engineers will emphasize Chain-Vey’s reliability, efficiency, or ease of integration into an existing process system. But sometimes a customer takes one look at the beauty of our tubular drag conveyor—maybe even the aesthetic of each intricate link of the chain—and that becomes paramount to the project.




So when one of the largest roasters wanted to build a real life Willy Wonka and the Coffee Factory, they built it with MPE’s Chain-Vey.

Talk to a sales engineer if the look of your process system matters to you too.
