Cold storage warehouse management is a highly specialized skill. It requires intimate industry knowledge and the ability to make the best use of materials, equipment and facilities. Good cold storage warehouse managers are intimately aware of their frozen product requirements. They continually respond to critical issues that arise when handling perishable foods.

Professional cold storage managers know about everything that occurs inside and outside their warehouses. They know specific challenges that face them and how to best navigate around those challenges.

Frozen food warehouse management takes years of dedicated learning and keeping up with emerging business trends. It also involves being current on technology. Good managers plan ahead to avoid frozen food warehouse management problems. They alsonetwork with others in the industry who help them with fresh ideas on where to source the newest cold storage industrial equipment, like the best plastic palletspallet invertersfreezer spacer removal modelsdispensersstretch wrappers and more.

Cold storage of frozen foods is a massive industry across America and around the world. Demand for food increases proportionately to the population — both of which are on a steady rise.

The frozen food warehousing specialty has specific requirements for temperature-controlled environments, and managers of facilities who handle these niche markets have their own industry challenges.

Your reputation, profits and ultimate success depend on recognition and successful management of these and many other common challenges. The largest segment of frozen foods is in the meat, cheese, poultry, seafood and dairy worlds that make up the mainstay of perishable food items.

Facility managers who handle these time- and temperature-sensitive products must be on top of their game to prevent small material handling mistakes that could turn into catastrophic financial losses.

In the cold storage world, little things really matter. Efficiency and product control are high priorities for cold storage facility managers. They must use time-tested processes as well as implement new industrial equipment that makes their business run more smoothly and, ultimately, more profitably. These professional managers must constantly look for systems and solutions that reduce waste, eliminate unnecessary cost and improve worker safety.

The fundamental goal is to prevent losing food products and profit. Different products require different temperatures for cold storage freezer food safety and product freshness.

It can be challenging and risky, and traditional temperature monitoring systems are percent dependent on operator experience. Someone must be onsite to manage the whole system is managed and make proper adjustments if temperature or humidity fluctuate. The upkeep process is about the quality and safety of the foods in your warehouse, which means you must keep a close watch and tight management over their conditions from the point of manufacture all the way through the supply chain to the point when they reach consumer hands.

Without this level of oversight, shipments of food products could undergo discoloration, textual degradation, microbial growth or bruising. At all times, you need to have accurate location information about the products that move through your warehouse, so you can determine affected products in situations with sudden or unexpected temperature changes.

Without exact traceability, it would be impossible to locate these products. Fresh produce and similar perishable products require even more management and control over external factors like humidity and carbon dioxide. You probably already know how crucial barcode labels are. They create the link between each physical product in your inventory and your computer systems that monitor receiving, storage, retrieval and shipments.

A single forgotten or lost label could lead to an unsafe or entirely ruined shipment. Freeze-grade labels appropriate for each product and situation are a critical factor in successful cold storage warehouse management, as they can develop a strong, permanent bond on common rack services. Your personnel can apply them in environments as low as negative 20 degrees Fahrenheit, and you can rely on them to stay on no matter what your daily operations entail.

Arguably, the most crucial part of cold chain process management is minimizing the amount of time it takes to push a product from the beginning to the end of the system. Staying efficient the entire time is critical. Without a precise level of effectiveness, the vulnerabilities we discussed earlier could begin negatively affecting the products.The Guide to Effective Warehouse Design, Maintenance, and Modernization provides engineers and operators of refrigerated warehouses with design, maintenance, construction, and repair guidelines for all major structures in The Guide to Effective Warehouse Design, Maintenance, and Modernization provides engineers and operators of refrigerated warehouses with design, maintenance, construction, and repair guidelines for all major structures in a refrigerated warehouse You are attempting to access content that is available only to certain members of the Global Cold Chain Alliance and its Core Partners.

Refrigerated warehouses, frozen food distribution centers and grocery freezers are the highest energy consuming sector per cubic foot in the world. To help reduce energy consumption and improve facility efficiencies cold storage freezers must be properly designed and built, and they must integrate the most energy-efficient systems available.

The Viking Cold TES system has no mechanical components and is the perfect solution to managing energy demand and load inside cold storage facilities. Being system agnostic, we leverage the existing refrigeration equipment to minimize energy costs while simultaneously maintaining temperature control.

Our Thermal Energy Storage system works well for new construction, retrofit or refurbishment projects. Representatives from all three companies discuss new efficiency technologies and trends for the cold storage industry, particularly in ammonia refrigerated facilities. The commercial and industrial application of our thermal energy storage TES technology has shown tremendous results in an ammonia-refrigerated frozen food warehouse in California. By storing energy in the form of cold and delivering discharge times up to 13 hours per day TES provides utilities a behind-the-meter distributed energy resource DER to help manage the inflexible and difficult demand profile of the cold storage industry.

Cold storage firm, Isla Frio Refrigeration Corp. Thesquare-foot building on eight acres is being fully renovated to become a state-of-the-art frozen and refrigerated food warehouse, beginning with 50, square feet of frozen storage. Over the years, Puerto Rico has been hit exceptionally hard by natural disasters and other crises, and with an unreliable power grid, these events inflict significant impacts on supply chain efficiency and functionality.

The recent coronavirus pandemic has also amplified the growing need for more cold storage capacity and the island-wide shortage of warehouse space. The recent acquisition of the PepsiCo plant provides an opportunity to build a highly efficient, energy-secure cold storage facility to support the recovering supply chain and electrical grid on the island.

These ambitious clean energy goals will drive the widespread adoption of renewable energy generation, which is complemented through the use of sustainable energy storage technologies like our TES systems. Phase One will be to install our technology and get the cold storage facility up and running by December.

Phase Two will build out the rest of the site and may eventually include an onsite solar power resource to assist in powering the facility.

Once the plant is operational with TES technology, carbon emissions and energy use will be minimized, enhanced energy resilience and flexibility will be in place, and the facility will benefit from lower electricity costs — a significant value on an island with among the highest electricity costs in the U. The building itself is connected to a large diesel generator to provide backup power and is built at a high elevation, better protecting it from floods.

During extended grid interruptions or power outages, the generator and its fuel can be conserved because the TES technology provides built-in temperature resilience to protect food up to several days without power. We are proud to again be working with another Puerto Rico-based company, this time to help them build their cold storage resources in a sustainable way right from the start.

Jake Denison is a product development engineer with Evapco. Although net zero energy buildings have been successfully demonstrated at residential and small to moderate commercial building scales, they have not been demonstrated for more energy-intensive operations such as food production or large refrigerated storage facilities.

The reason is simple: residential and low-rise commercial buildings have the benefit of considerably lower energy use intensity i. Figure 1 shows the comparative energy use intensity of various facility types including: a food production facility with refrigerated storage, a health-care facility, a large cold storage warehouse, a commercial office building, and a single-family residential dwelling.

The high energy use intensity of a food production facility significantly increases the degree of difficulty and costs for achieving net zero energy performance. One factor that increases the degree of difficulty in implementing sufficient renewable energy production on-site is the large area required to deploy sufficient renewable energy generation to power a food process or refrigerated storage facility.

This area is significantly larger than the facility footprint that might use rooftop photovoltaic solar alone. The analysis presented in this article will show the magnitude of land area required to power such a facility.

We also quantify the costs for deploying sufficient renewable energy generation to achieve net zero performance; however, land costs are not included in the economic analysis due to the significant variation in prices based on location. The analysis presented in this article is based on an actual refrigerated warehouse comprised of two separate refrigerated docks, a cooler, and three freezers totalingft 2 15 m 2 of conditioned space.

The size and respective temperature setpoints for each of the refrigerated spaces in the facility are given in Table 1, and the actual metered electrical energy demand and consumption for the facility are used in the analysis that follows.

More specifically, the on-site renewable energy production is sized to annually produce electrical energy equal to the facility electric energy consumption. We assume the facility is grid-connected and the electric utility provides necessary electric power whenever the site electrical demand exceeds the on-site renewable electricity production. We also assume the utility accepts any surplus on-site electricity production during periods when the facility electric demand is less than the renewable energy production.

Stack effect in heated buildings, caused by the buoyancy of warm air, generally creates negative pressure on lower levels of a building and positive pressure at higher levels. In refrigerated buildings, the stack effect is reversed. Moisture-related damage in cold storage buildings can vary from minor exterior or interior staining to complete failure of the building enclosure, including structural failure of concrete slabs-on-grade.

There are two primary types of cold storage facilities—detached and attached. Detached facilities are buildings constructed for the sole purpose of producing or storing goods at low.

Failure to follow these general guidelines can result in a variety of condensation problems. Insufficient insulation in exterior walls and roofs can result in cold spots on the exterior of the building. The consequences of insufficient insulation can range from increased energy use to condensation or even frost formation on exterior surfaces. Thermal bridging through refrigerated enclosures is less of a problem in buildings that use continuous insulated panels as either the exterior walls or as a component of those walls.

The most effective enclosure system for a building depends heavily on the exterior climate. A less visible until failures occur form of condensation is interstitial condensation within wall and roof assemblies.

This creates a relatively constant condensation risk for the majority of the year, and outside air that enters the building could condense on interior surfaces. This effect tends to draw humid air into the building near the ceiling above the space, typically through roof-to-wall joints. Humid air infiltration can be problematic in buildings with attic spaces above the main cold spaces, especially if the ceiling insulation below lacks sufficient vapor resistance. Photo 1 shows the result of long-term condensation in ceiling insulation that resulted in its eventual overloading.

During our investigation of this building, we found that the insulation board had absorbed 10 to 15 times its weight in water. Humid air infiltration into the attic combined with a discontinuous vapor retarder above the insulation contributed to widespread structural failure of the ceiling.

Photo 1. Photo 2. The overall strategy of installing continuous air and vapor barriers on the exterior of the building and using continuous, high R-value insulation must be followed in both the field of the wall and roof areas as well as at all transitions.

A relatively common problem can occur when refrigerated rooms are inadequately insulated, resulting in condensation and possible microbial growth on their exterior surfaces, as well as on the interior surfaces of the adjacent spaces.

Photo 3 shows the exposed concrete ceiling in a retail store below a supermarket freezer room. The pink and black coloring on the concrete is microbial growth due to constant and heavy condensation. In this case, the minimal insulation in the freezer floor became saturated with water from floor washing operations, further reducing its insulating value.

Photo 3. This is in contrast to typical exterior walls, where cold temperatures in the winter generally correspond to low interior moisture levels, and seasonal temperature swings and solar exposure provide warming and drying periods for any condensation that forms in the walls.

High RH levels in the warm-side spaces create a vapor drive towards the slab. For a typical arrangement of a poorly insulated slab above an occupied space, the direction of water vapor flow will be toward the slab for the entire year. This creates the need for a strong, continuous water vapor retarder, such as continuous aluminum foil, on the warm side of the insulation.

Without sufficient vapor resistance, water vapor flow through the insulation can cause concealed condensation on the slab and within the insulation. This can result in problems ranging from concealed microbial growth Photo 4 or failure of the insulation due the weight of the stored condensation. Photo 4. In this scenario, the shell provides the primary weather barrier for the building, protecting the inner enclosure—which provides the insulation, air, and vapor barriers—from degradation due to weathering.

Refrigerated-Facility Design

A partially conditioned or unconditioned corridor space between the enclosures can be used for maintenance or inspection of the primary enclosure. If appropriately ventilated, the corridor space can help to reduce the thermal load on the refrigerated enclosure, for example, by reducing the effects of solar heat gain. Although much more reliable than a single enclosure, the building-within-a-building concept is more expensive to design and construct.

Due to these constant low temperatures, active solutions such as slab heating pipes or ventilated crawlspaces are typically needed to prevent frost heaving in refrigerated buildings.Optimizing your warehouse reduces the time it takes to complete each task.

Streamlined tasks keep workers happy. Happy workers equals reduced absenteeism and greater productivity. Greater productivity equals efficient operations. And efficient operations equals happy customers, which leads to a profitable business. Understandably, revamping your entire warehouse operations sounds stressful. After all, a warehouse is massive by design, and you still have to keep your business running in the meantime.

Take a deep breath, think about the future benefits, and let the following phases guide your warehouse layout redesign:. Altogether, these phases make up the project lifecycle, which is a proven way to keep large projects on track. Taking a project management approach to your warehouse layout redesign can make the job less intimidating by breaking it down into manageable tasks.

Addressing these concerns is important. One study shows that useless or inefficient tasks have a negative effect on the mental health of workers. If your warehouse management system WMS uses mobile scanners or radio frequency identification RFID technology, you can readily assess your data to understand the flow of goods through your warehouse.

Knowing the total landed cost of each item allows you to understand which particular items are driving your revenue. In the planning phase, you outline the work to be done, the tasks and resources needed, and timeframes. By the end of this phase in your warehouse redesign project, you should have:. You can either use an existing map, manually draw a map, or use technology such as the warehouse layout and design software SmartDraw.

Furthermore, identify the operational locations of your warehouse on your map. Laying them out clearly will allow you to consider every movement and activity within your warehouse. Examples of operational activities include:. Your planning efforts will depend on your unique business. Generally, every warehouse layout redesign effort should consider the following elements :.

Prospects of Powering a Refrigerated Warehouse with Renewable Energy

Start by listing your key processes, and then draw the workflow directions of those operations. Use different colors - either on paper or in your software - to draw the secondary operations that follow these main processes. Use your earlier conversations with warehouse workers or the information from your WMS to create an accurate representation of the different workflows.
