Verena Street Tube Conveyor Case Study
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:

每个系统都需要灵活的员工处理多种混合物、批量大小、研磨、风味等。此外，Verena 的所有者需要能够随着预期增长而扩展的系统，而无需更换尚未获得投资回报的输送机和设备。Verena 充分利用了自己的处境，从零开始建立了一个新的业务;咨询 MPE 工程师，明智地布置每个系统，以确保手提箱的运输便利性、工人的安全移动以及设施对白标客户的整体美感。其他工程考虑，如管状输送机弯头的大范围扫掠和额外的出口（用于研磨机和手提袋），确保了每个系统在全速和全容量下的运行寿命。

MPE’S SOLUTION:

调味系统： 取装烘焙咖啡的手提袋，转移到搅拌机中调味，然后转移回手提袋中

研磨系统： 将咖啡从手提袋转移到研磨机，然后再回到手提袋中

混合系统： 取一袋新鲜烘焙的咖啡，分批指定数量的咖啡进行混合，然后将混合物转移到手提袋中

调味系统

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.

研磨系统

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.

混合系统

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 现在拥有一个陈列室品质的设施，拥有三个 MPE 设计的系统。Verena 共同拥有适合其当前业务需求的灵活性和运营效率，同时为未来的增长做好了充分准备。他们的白标业务特别有望从这种易于扩展的产能中受益。Verena Street Coffee 的 Chain-Veys 享有可靠的运输工具，MPE 研磨机无与伦比的研磨质量，以及 MPE 工程师从过去数百个系统集成中利用的专业知识，这些都融合在一起，使 Verena 拥有中西部最珍贵的烘焙厂之一。
