Sun’s rays cool milk

SPAIN – Research carried out at Spain’s Public University of Navarre has produced a prototype for cooling milk using solar energy.

The system involves one cylindrical tank, which acts as a cooling chamber for milk within a tank of frozen water allowing the milk to be cooled without using a pumping system.

The energy produced during the conversion from ice to water is used to store solar energy when the sun’s irradiation is high, and that energy can be used for the second milking at night.

The system can store milk for 60 hours at 80% of its capacity. According to the university, the results of the cooling efficiency of the system are similar to those reached by the usual systems, which use electrochemical batteries to store energy.
