Doubling up on cold-storage automated storage and retrieval systems AS/RS gains

When your mission spans from “cow to carton” in supplying consumers with high-quality organic dairy products, efficient storage and order picking at the cold storage level ensures those cartons flow to retailers and consumers efficiently and accurately.

That flow of products for Aurora Organic Dairy starts at the cow, but efficient warehouse storage and order picking automation keeps that flow of goods as efficient as possible.

Aurora Organic Dairy (AOD) is a leading producer of store-brand organic milk and butter for U.S. retailers, operating several farms and facilities across the nation. Based in Boulder, Colo., it oversees heifer farms and organic dairy farms in Colorado and Texas, as well as organic dairy processing plants in Platteville, Colo., and Columbia, Mo.

Aurora manages the entire product lifecycle—from its farms to its processing facility—with a dedication to organic standards and sustainable production at every stage. To meet these standards and ensure the highest quality product for their customers, Aurora needed an efficient solution to build an in-house cold-storage warehouse and turned to a provider of automated storage and retrieval system (AS/RS) solutions (Westfalia Technologies) to make that happen, starting with its plant in Platteville, Colo.

The company’s integrated cow-to-carton model began in 2003 with an on-farm milk plant in Platteville. Its organic dairy products are distributed nationally, and AOD has a large inventory of extended shelf life (ESL) products, which helps to balance supply and demand while providing excellent customer service levels.

As AOD grew through new channels and expanded its product assortment, the company outgrew third-party warehousing and needed a small-footprint, in-house cold storage facility on-site at its milk processing plants.

Challenged with a lack of space to accommodate a large warehouse addition, Aurora reached out to Westfalia to design an AS/RS solution. The AS/RS allowed them to build a highly automated cold storage warehouse adjacent to the milk plant to accommodate growth in limited square footage, while transforming the entire warehousing process from production to shipping to staging.

The AS/RS in Platteville enables efficient storage and order picking, using a system like the one shown here, but with two pallet cranes.

“As a company with a strong foundation of sustainability, we liked that we could build a smaller warehouse for long-term energy savings,” says Joe Harmon, senior manager of technical resources at Aurora Organic Dairy. “We also felt that Westfalia offered a more flexible design than other companies. The racking design allowed us to build a custom facility based on the sheer number of pallets we needed to store on the square footage we have available.”

The custom solution is tied directly to production, allowing flexibility to process orders in advance. With pallet accumulation on the inbound and outbound system, orders can be fed to the dock to allow for quicker truck turns.

In addition, two high-speed tandem pallet cranes provide the high throughput necessary to support future growth. This makes the production and distribution process more efficient, and it eliminates the need for manual touches, reducing labor costs and improving product freshness and quality.

“The biggest challenge to implementation was that we were running the plant and producing products during the warehouse construction and commissioning process,” says Harmon. “Westfalia was a great partner to be able to work with a fully operational facility and allow us to keep it running while they completed the commissioning of the warehouse, train employees and troubleshoot any issues.”

When it came time to expand again, Aurora decided to build a second dairy processing plant in Columbia, Mo., and again selected Westfalia to design, manufacture and install an AS/RS for that cold storage warehouse in 2018. While the AS/RS solution was similar to the Platteville installation, the Columbia location was a greenfield site, which offered greater flexibility in square footage, capacity and solution design.

Without space restrictions, Westfalia designed an AS/RS with a true outbound staging system. With two outbound staging lanes to pre-stage products ahead of time, trucks at the Columbia warehouse can turn in under 30 minutes at the dock.

“We developed a solution that worked well for us in Colorado, so it was natural to implement a very similar solution for our second location,” Harmon says. “The fact that the warehouses are so similar and designed by Westfalia also provides flexibility in maintenance and training between the two facilities, as well.”

The addition of the Columbia warehouse meant Aurora could expand its product offerings to customers and ship milk from another key location. Aurora’s continued partnership with Westfalia resulted in another streamlined production and distribution site, with even faster truck turns and higher throughput.

In addition, Aurora saw cost savings from building an in-house solution, rather than relying on third-party cold storage providers. A consistent AS/RS design has also allowed for simplified training and maintenance across facilities, with assistance from Westfalia experts to keep the AS/RS solutions, and the flow of goods, running smoothly.
