Cold Chain Logistics For Perishable Cargo Transportation
Perishable products are those items which are likely to decay faster if not kept in a cold surrounding. These products need a lot of care while being handled to keep them safe for long. Perishable foods include fruits, vegetables, meat, seafood, and dairy products; all these products are likely to be spoilt at high temperature. The temperature variations make the perishable items decay easily. Customers who buy such perishable products will only eat them if they are safe to eat. So these items need extra care. This requirement can be fulfilled by keeping them safe in cold temperatures.
Here are some other features of perishable cargo transportation:
- Fulfillment of the load integrity requirements: The perishable cargo transportation is possible only with the cold chain which includes refrigerated units, the energy required to run them and load integrity requirements. A logistical cold chain helps to manage the transportation of perishable goods so that customers receive fresh goods, and thus the retailer companies gain substantial profit because if the products decay, no one will buy them and it will prove a loss for the company.
- Transportation of temperature sensitive products: The cold chain includes the transportation of temperature sensitive products like perishable goods along a supply chain with the help of thermal and refrigerated packaging methods. It requires proper logistical planning to protect the integrity of these products. The quality of perishables products degrades with time and temperature variations. Since they have chemical reactions in high temperatures, that's why they must be kept in low temperature for a long safe life. Their transportation from one country to another or within a country requires a good establishment of cold chains in a very organized manner.
- A mixture of Science, Technology, and Management: The cold chain is particularly a mixture of science, technology, and management. It is science because it understands the importance of chemical reactions which destroys the perishable products. It is technology because it uses good technical products like refrigerators to keep the perishable products safe for a long time. It is a process as it includes a series of tasks which consists of the preparation, storage, transportation, and monitoring of temperature-sensitive products like perishable foods. So a proper cold chain requires logistical planning of various processes.
- Reduction in public health problems: The cold chain reduces the public health problems caused by deteriorated foods since the proper transportation of perishable food products with a proper logistical cold chain process minimizes the likelihood of bacterial, microbial and fungal contamination. It provides the required temperature to the products which keep them safe for a long time and thus they can be transported from one country to another without getting spoiled. It manages the relationship between a producer and a customer by providing a maintained goods service.
Dry ice, gel packs, liquid nitrogen, refrigerators are the methods used for the cold chain management of perishable products. For perishable cargo transportation, mostly refrigerators are used because they tend to maintain the low temperature for a long time during the long journey from one country to another. A logistics cold chain retains the freshness of products which are likely to deteriorate quickly due to the chemical reactions of bacteria is present in high temperature.
