University of Agricultural Sciences (UAS)-Bengaluru Introduces Budget-Friendly and Sustainable Raw Milk Cooling Solution

CT Ramachandra, Prof and Head, Department of Processing and Food Engineering, UAS-B said the solid-state cooling module or the mini-cooling unit has been developed under a World Bank-funded project and is ready for commercialisation.

Peltier Effect

The mini cooling unit has a capacity of five litres and runs on electricity. It can also be operated using a 12 volt battery. The solid state cooling module is an alternative to the conventional cooling system and works on the principle of Peltier Effect, Ramachandra said. “Unlike the conventional refrigeration system, which releases CFC gases due to the use of refrigerants as cooling media, this solid state cooling module does not emit any harmful gases and is an eco-friendly green technology,” Ramachandra said. However, the cooling efficiency of this solid state refrigeration unit is marginally lower than the conventional refrigeration systems.

Small dairy farmers in villages and remote areas can use this mini cooling unit to bring down the temperature of the milk, before pouring it at the local collection centres. When milked, the temperature of the milk that flows from the cow’s udder ranges around 35-37° C and has to be cooled to less than 10 degrees to reduce microbial activity. The developed refrigerator module will help bring down the temperature and maintain it less than 10° C, Ramachandra said.
