The project developed, designed and marketed on-farm biogas milk chilling (BMC) systems. The system had a capacity of 20-40 litres, powered by biogas energy directly through sorption cooling. The project offered affordable chilling equipment for smallholder dairy farmers and an off-grid chilling option by powering chilling systems with renewable energy.
With the support of the EEP, Biogas Milk Chillers have been installed throughout Tanzania and Kenya and the project has demonstrated the unique design, reliable technology and viability of the business case of SimGas. In 2016, SNV and SimGas completed testing of 15 working prototypes in two regions in Tanzania and Kenya. These units proved that the new technology enables 10L of milk to be cooled from 35ᵒC to 4ᵒC off-grid and within three hours (compared to 21 hours using an electric refrigerator).
