Solar Pasteurisation

Pasteurisation of milk today is done using steam generated by burning a fossil fuel or using electricity.The following diagram depicts the entire process of milk processing:

Entire process of Milk Processing and Packaging

As can be seen from the above process diagram, milk processing involves two process that require heat:

1. Pre-Pasteurisation
2. Pasteurisation

Both processes do not require more than 90 deg C temperature. This can be provided by Solar Concentrators.

Diaries are ideal for implementation of Solar Thermal Systems as they do not have constraints of space for solar concentrators.
