Follow the story of EvaKuula and the innovator behind the technology, Dr. William Kisaalita, a professor at the University of Georgia whose nonprofit entity, the University of Georgia Research Foundation, developed a biogas-powered milk chiller benefits smallholder dairy farmers by decreasing milk spoilage and increasing production and profits and biogas for lighting and cooking.
UGARF is being honored for the EvaKuula, their biogas-powered evaporative milk cooler. AE50 awards have been encouraging and applauding engineering achievements since 1984. Entries are evaluated by a blue-ribbon, international panel of industry experts in technology, design, and product development.
William Kisaalita, a professor at the UGA College of Engineering, feels strongly about giving back to his native country of Uganda. To do this, he created the Evakuula, which uses biofuel to heat fresh milk, killing the bacteria, and then uses evaporative cooling to chill and preserve it for market.
In May, the team visited UGARF’s milk production facility, two smallholder farms where the deployed milk chillers are installed, a local business that is part of the supply chain, and a vocational carpentry school where the thermization units for the milk chilling process are made.
The University of Georgia’s William Kisaalita discussed the challenges of developing a reliable cold chain in Uganda in a recent article on NPR’s The Salt, “Why You Shouldn’t Take Your Milk’s 3-Week Shelf Life for Granted”
William Kisaalita of the University of Georgia Research Foundation discusses their refrigeration unit powered on biogas extracted from cow manure. Reusable zeolite plates capture water vapor from the evaporative milk chilling process.
A University of Georgia engineer has received $1 million to continue working on a milk cooler designed to help dairy farmers, particularly those in sub-Saharan Africa, who lack access to refrigeration, according to a news release from the university.
