The milk cooler, developed by William Kisaalita, a professor of biological and mechanical engineering in the UGA College of Engineering, uses the principle of evaporative cooling to quickly bring the temperature of milk to a safe holding temperature.
“It’s the same phenomenon that occurs when you jump into a swimming pool and then you come out on a windy day,” Kisaalita is quoted as saying in the news release. “If there’s water on your skin, you will feel cold. This same principle is applied in chilling the milk.”
According to the release, Kisaalita received the funding from the U.S. Agency for International Development in partnership with the Swedish government, Duke Energy Corp., the German government and the Overseas Private Investment Corporation. Kisaalita’s was one of 12 international projects selected from 475 applications to share $13 million in funding under the USAID program “Powering Agriculture: An Energy Grand Challenge for Development.
