World Refrigeration Day: Cold Chain 4 Life - STICKERS in the six UN languages

Cold Chain 4 Life - The Cold Chain Connects the World - posters in the six UN languages for World Refrigeration Day

The cold chain is a series of actions and equipment applied to maintain a product within a specified low-temperature range from harvest/ production to consumption, including farming/fishing, food processing, cold storage, transportation, food services, and domestic uses, as well as special products like medicinal products and vaccines.

For consumers, the cold chain is often associated with transport, retail and household refrigerators. But refrigeration is also and widely used in the agri-food industry for the storage of raw materials and final products, as well as for food processing. This brief gives a short overview of refrigeration applications in the industry. The… read more

Cold storage warehouses store food after production and before foods are transported and distributed to supermarkets or catering establishments. Food is stored either chilled or frozen and may remain in the store for periods of a few hours, days or even a year (for some fruits and vegetables) in chillers and up to several months in freezers.… read more

This brief provides an overview of the main areas of transport refrigeration, some of the different systems used and the working fluids employed. It will go on to look at current trends in using alternative refrigerants and the direction the sector is moving in over a longer period. Future developments will be discussed along with the technical… read more

Due to the complex nature of the cold chain and the high temperature dependency of post-harvest or post-mortem deterioration in food, temperature control in the food chain is vital. Temperature control tends to become less well controlled at the retail/professional and domestic stages of the cold chain. The food chain is responsible for… read more

This brief will present the process needs and applications of refrigeration onboard refrigerated fishing vessels. Currently used technologies and refrigerants will be presented, along with the possible alternatives for new systems.
