الملخص EN

A device for pasteurizing and cooling milk by solar energy was designed, manufactured, and its efficiency was studied and tested.Consists of solar collectors for the first pasteurization unit and the second cooling unit.

The results showed that all the energy of solar radiation and pickup energy and the efficiency of solar collector and the percentage of recovered energy and productivity was increased with the increasing daylight hours and the maximum values have ranged between twelve o'clock and one in the afternoon and then declined thereafter.

The results showed that the average energy of solar radiation in summer and winter were 741 673 W / m 2, respectively, and the rate of efficiency of the solar collector was 40.7%, 46.8%, respectively, and the rate of energy recovered 66.81, 58.53%, respectively, and the rate of productivity 20.20, 13.76 liters / h respectively.

The test results the chemical and microbiological showed the process pasteurization efficiency by solar milk pasteurization device.
