This paper investigates physico - chemical and microbial analysis of solar powered milk processor which involves application of solar energy in pasteurisation of milk in batch processor. Photovoltaic (PV) cells were used to convert solar energy in to electrical energy through photoelectric effect. The batch processor was designed for 40 Litres capacity using Auto Cad Inventor software and developed using SS 304 material with water level indicator and temperature control circuit. Suitable trials were conducted to validate the developed equipment by conducting physico - chemical and microbial analysis for the processed milk samples. Comparative studies were made between conventional processing and solar processing of milk. The shelf life of the solar processed milk was compared with the conventional pasteurised milk. It was observed that there was no significant difference (p>0.05) difference in shelf life between the control samples and solar processed milk samples. The standard plate count in solar processed milk samples was observed to be (4.00±0.00) for all treatments and was found to be within limits. No coliforms were present in all the processed samples.
