由于几个原因，撒哈拉以南非洲农村地区的小奶农无法将晚间牛奶运往市场。他们无法获得电网电力来为传统的冷藏系统供电，这些系统将牛奶保存在第二天的市场上。由于安全问题和路况差，他们无法在夜间运输，特别是在饲料丰富的雨季生产高峰期。一种涉及热化（58-63 °C持续30秒）和低成本蒸发冷却相结合的解决方案已被证明是有效的，并已在乌干达Wakiso、基博加和Rakai地区的30个目标用户手中成功测试。这些奶农生产的所有冷却后的晚奶都已成功进入冷链，经过刃天青分析评估，刃天青分析通常用于收集中心或买家评估新鲜度。根据冷却系统（EvaKuula）的制造成本和早期采用者每天晚上的牛奶销售量，农民需要大约20个月的投资回收期才能完全拥有EvaKuula，以租赁的商业模式。目前正在开展工作，以进一步扩大EvaKuula在该区域的采用。
Smallholder dairy farmers in rural settings of sub-Saharan Africa cannot get their evening milk to markets because of several reasons. They do not have access to grid electricity to power traditional refrigeration systems that preserve their milk for market the next day. They are not able to transport at night due to safety concerns and poor road conditions, especially in the peak production rainy season, marked by high abundance of fodder. A solution involving the combination of thermization (58–63 °C for 30 s) and low-cost evaporative cooling has been shown to be effective and has been successfully tested in the hands of 30 target users in Wakiso, Kiboga, and Rakai districts of Uganda. All cooled evening milk by these farmers has successfully entered the cold chain, after assessment with the Resazurin assay, commonly used for evaluating freshness by collection centers or buyers. Based on the cooling system (EvaKuula) fabrication costs and daily evening milk sales by the early adopters, a payback period of approximately 20 months is needed for farmers to completely own the EvaKuula, in a rent-to-own business model. Work is in progress to further scale-up the EvaKuula adoption in the region.
