New technologies have made it possible to get fresh, perishable foods from one side of the world to the other without putting the integrity of the foods at risk.
Similarly, state-of-the-art temperature controlled containers and trailers make it possible to get valuable, perishable biopharmaceuticals to areas of need.
But as much as we talk about refrigerated transportation, we often forget to talk about one of the aspects of cold chain logistics that makes it possible: cold storage and refrigerated warehousing.
After reading this post, you will know about how cold storage is used, the different types of cold storage, and how refrigerated warehousing makes the entire cold chain possible.
Cold storage is the storage of any temperature controlled substance that prevents that substance from decaying or not adhering to laws and regulations that apply to that item.
1. A manufacturer may have a private cold storage facility to warehouse products before they make their way to end users.
A Minneapolis-based meat packer has a private on-site cold storage facility and operates a private fleet.
2. End users may have cold storage facilities to store temperature controlled products after they’ve received them but before they have a need to use them.
A large Chicago hotel chooses to purchase food in bulk and store all temperature sensitive items in an on-site private cold storage unit.
3. Most commonly, cold storage is outsourced to a third party logistics provider (3PL), where products stay until they are ready to be shipped to an end user.
A large Wisconsin cheese producer opts to use a 3PL’s cold storage facility to store all of its temperature sensitive dairy products.
Because of the regulation surrounding refrigerated freight, cold storage is much more complex than its dry counterpart.
Refrigerated warehousing tends to be more costly, so many manufacturers opt to outsource their cold storage to third party logistics providers.
As demand for the transportation of refrigerated goods increases, so does demand for value-added services such as repack operations and consolidation. Customers tend to have more stringent requirements for the 3PLs they are outsourcing to, since retailers and end users have higher expectations when it comes to pallet building and traceability.
Because of these heightened expectations, 3PLs tend to have a lower return on investment for cold storage, and have to do everything possible to optimize their processes and facilities in order to remain profitable.
Since customers have an increasing number of specific demands based on the needs of their end users, many 3PLs struggle to operate one-size-fits-all warehouses.
With so many diverse customer needs, it’s become more common for 3PLs to create custom cold storage facilities for their customers.
While this allows 3PLs to work more efficiently based on the needs of a particular customer, it can be a risky endeavor, as it can be hard to lock price-sensitive customers into long-term contracts.
Diverse customer needs are shaping the evolution of the cold storage industry—and these needs are not limited to added value services.
They also have to do with the nature of the goods themselves being stored .
Different products have varying shelf lives, ranges of temperatures they are required to be stored at, and amounts of time they can spend between the cold storage facility and a transportation vehicle before spoiling.
Some examples of products that may require cold storage or at least a temperature controlled warehousing solution:
To make things even more complex, there are food and product safety regulations attached to each type of product that requires temperature controlled transportation and storage.
Energy efficiency leads to another cost-related concern.
Studies have shown that refrigerated warehouses and cold storage facilities can be incredibly inefficient if they aren’t equipped with the highest quality doors and insulation, and if the warehousing process isn’t optimized to limit exposure of the open warehouse to the outside world.
There are many different types of cold storage, from individual units to entire dedicated facilities.
Let’s explore some of these types:
Refrigerated containers are the most basic and often the most cost effective option for cold storage of small quantities of temperature sensitive products. They can also be mobile, which gives them the advantage of extra flexibility.
Blast freezers and chillers are ideal for companies who need to quickly cool and store food before it reaches its end consumer. It’s common for some larger restaurants and catering companies to use them.
Cold rooms are exactly what they sound like. They are a larger alternative to the options listed above.
Hospitals and research institutions may make use of pharmaceutical grade cold storage units. These units are equipped with extra features that make them ideal for biopharmaceuticals, blood, and certain vaccines.
Plant attached cold storage is the preferred option for some manufacturers who want to keep their cold storage in house. Products can be transported via conveyor straight from manufacturing to a dedicated cold storage facility on-site.
As we discussed above, many companies that use cold storage have complex needs based on the nature of their products and the preferences of their end consumers. Those who choose to avoid the cost of an on-site facility will opt to use a custom or dedicated cold storage facility provided by a 3PL.
At Winnesota, we are committed to providing exceptional Midwest refrigerated services. With over 20 years of experience, we understand the precise art of transporting and storing temperature controlled shipments.
Because of this, we've added refrigerated warehouse space in our Eden Prairie, Minnesota facility, as well as a larger cold storage warehouse in our Oconomowoc facility.
Our new cold storage spaces are ideal for customers who require refrigerated cross docking and distribution. Why not leave refrigerated product delivery up to us instead of incurring all of the expenses it would take to operate a private fleet?
If you've been using a refrigerated transportation company and a separate cold storage facility, we can help you streamline your business by taking care of both!
Our Oconomowoc facility is located directly across the street from the Roundy’s Distribution Center.
Large distribution centers like Roundy's are sometimes very difficult to deliver to because the volume of trucks delivering shipments to them often forces drivers into making appointments, which can in turn cause drivers to run out of hours or service.
This can lead to a whole host of issues, including additional fees for waiting (detention time) which get charged back to the customer, and general delays for other deliveries or jobs the driver may have.
With our location being right across the street, we can accept the product, store it, and deliver to Roundy’s so that their driver can keep moving and continue making money rather than sitting idle and causing delays.
It's a win-win!
When it comes to maintaining the integrity of refrigerated and temperature controlled goods, and getting them to their destination on time, it’s important to work with an experienced, reliable company.
At Winnesota, we’ve learned the ins and outs of the cold chain through years of experience.
