 In many countries, milk is exclusively produced by small and medium sized dairy farms with daily milk output below 200l. Their milk is in most of the cases transported to milk collection facilities, without any form of cooling. In addition, lack of hygiene and cleaning procedures and problems with cattle health are the most common reasons of high bacterial growth during short-term storage of milk on the farm and during transportation.

 One system includes 24 reusable plastic blocks of 2 kg capacity and two 30l insulated milk cans with removable ice compartment. The smart ice-maker is powered by 600 Wp solar PV modules together with two batteries with a total capacity of around 1.5 kWh. Thanks to the thermal energy storage, in form of the 24 2 kg-Ice-blocks, the system is able to run autonomously for up to 5 days even during periods of low solar radiation and high ambient temperatures.<ref name="2013-2016 Victor Torres Toledo, Ana Salvatierra Rojas, Alice Hack, Joachim Müller.

 Cylindric tins are used for the production of ice, which is then put into the ice-compartment of the Insulated Milk Can. Depending on the amount of milk and ice, different cooling temperatures and storage times are reached.
