Solar-Powered Milk Coolers Proposed For Rwandese Dairy Farmers

“Sometimes, a farmer milks the cow and will wait for two hours until he will transport the milk to the [milk] collection centre. The milk is hot such as at 35 degrees, [and] the climate is hot. So, the milk is fermenting, and every 20 minutes, the number of germs in the milk doubles, and the quality of milk is deteriorating,” he said as he explains an instance of impact of lack of effective cooling system to the milk.

The remedy to the very quick cooling, and to do this, you need to have cold system just near the farm, or at the farm itself.

“...we have some new equipment that are actually very low energy consuming, and they can be run easily by solar or normal single-phase electric power...with this equipment, you can cool the milk very, very quickly, just near the cow, so that each farmer will become like a milk hub, and all these milk hubs [farmers] will deliver the cold milk to the milk [collection] centres.”
