Researcher develops tool to keep milk fresh and raise income for sub-Saharan Africans
Immediately after heating, the milk is transferred to the cooler, which uses evaporative cooling to chill the milk to about 10 degrees below room temperature. The mechanics behind the process are relatively simple.
“You know how when you are in a swimming pool and you jump out on a windy day, you feel very, very cold? The reason you feel cold is because the water drops on your body are evaporating and taking some of your body heat with them.”
Evakuula’s cooling process works the same way. The milk is placed in a cooler with an attached fan that hastens the evaporation of water droplets off the milk canister.
The milk container doesn’t take up the entire Evakuula cooling canister, so farmers like Sebuufu are also able to use it to cool and preserve other food for their families.
“With the Evakuula, evening milk is sold, and I have more income. Life is better,” she says.
As for Kisaalita, he’s not satisfied stopping with milk. He and his team of researchers are now using the Evakuula technology to create a cooling container for eggs.
“This is the land that gave me birth. This is my opportunity to give something back.”
