Although it has not always been a necessity, cold storage is an integral part of all civilization. The use of Cold storage is for items that may spoil whether it is food, medication or even electronics that cannot be left out in the heat. For this very reason, cold storage is particularly valuable simply for its benefits of the prevention of spoilage or damage to stored items. Worldwide, cold storage may come in many forms. However, regardless of form, cold storage has become a part of the fabric of society and a lack of cold storage is akin to lack of oxygen for the general global populace.
Cold storage systems have been around for several millennia and in many different forms. In the history of Italy, for instance, there are cold storage rooms within caves in the mountains for cold storage of wine or cheese.
Although these are ice free cold storage units, there are notable cold storage units that use ice. In the American west in the nineteenth century, cold storage systems usually consisted of an ice house, cold storage facility, or even the precursor to what people know today as non-cyclic refrigeration (as opposed to the modern refrigerator or freezer that contained ice and cyclic refrigeration, in which there is a removal of heat from a low-temperature space).
In some units, companies transport ice from as far as the Arctic or as high as the mountains and brought back down to local towns. These types of cold storage systems are still used today, and while it may seem old-world to some, combination of cold storage machinery and new technology makes these cold storage facilities equally valuable to any refrigeration system.
In recent years, cold storage facilities, systems and even units have changed due to new technology and cold storage machinery. In the United States, refrigeration or cold storage comes in many forms including large meat lockers and household cold storage systems such as the refrigerator or stand-alone freezer. In Europe, although similar in nature the refrigerators are smaller to fit the needs of the average consumer; Europeans buy food once a day instead of once a week for storing as Americans do.
Cold-food storage takes yet another form for companies dealing with items that can potentially spoil. From factories that make popsicles that require cold storage machinery conveyer belts within the cold storage system to facilities that are straightforward cold storage units for items that may expire under heated temperatures, cold storage has become prominently displayed in nearly every country globally.
Even oil refineries use cold storage systems to keep the oil cool and avoid explosive disasters. The versatility of cold storage alone is beneficial to potential customers regardless of needs.
