The cold chain is a set of actions and steps taken to ensure safe and undamaged transportation of temperature sensitive products. No doubt, technology has made the world smaller, but the physical separation between continents cannot be ignored, especially while dealing with transportation.
Goods while transporting can be damaged due to any shock, irregular temperature changes, poor packaging, etc. While the shock and poor packaging can be looked after, regular temperature changes can be efficiently managed by a cold chain. However, this is not just as easy as it seems to be. For goods labeled to be perishable, the importance of cold chain logistics India becomes even more prominent. These perishable food items degrade with time, and a delay can cause losses since temperature higher or lower than a particular range can cause several chemical reactions to occur.
The cold chain logistics holds an important position in the medical, pharmaceutical, and food business and has the following elements involved in the process:
Bringing the goods such as food or medicines to the designated temperature system.
Storing the goods at the required temperature without any changes for a number of days while traveling places.
Having a proper network of transport to deliver the goods to the destination with the same facilities, including temperature, safety, etc.
Helping in distributing the goods to the consumers and ensuring that they are integrated and safe to be consumed.
Cold chain development isn't just about a single country or place, but all the countries are involved in the distribution process. This development is a result of the increase in demand for fresh and best quality food items. People with high economic status are beginning to pay attention to consuming food that is newly harvested and beneficial, no matter how much does it cost.
There are industries who completely rely upon their cold chain services for their profits and losses. Cold chain is not just a process but a science which protects industries from suffering severe losses. It is a science that understands both chemical and biological aspects. The chemical aspect decides the plan of action while the biological aspect decides the precautions to be taken. The technologies involved in the process are:
Dry ice is solid carbon dioxide and has a temperature of about -80°C. It is required when the shipment process is longer and could take a number of days. It can cover all the four stages of shipment, namely cooling system, storage, transportation, and distribution. It has three times the refrigeration power of normal ice and is convenient to use since it does not melt; rather, it sublimates into the air.
A number of pharmaceutical products need to be stored in the temperature range of 2 to 8°C. These, however, melt into liquids and can maintain the temperature required for shipment.
A dangerous substance but still maintains a temperature of -196°C. It is used to transport tissues and organs.
There are many other technologies used to accomplish the task of safe and sound delivery, such as eutectic plates, quilts, refers, etc.
