The Dairy Procures wholesome fresh milk from different village co-operative, Milk Unions, State Federations all over India and is transported to our plant through Insulated Rail Milk Tanker & Road Milk Tankers.

The incoming milk at the Dairy is rigorously tested for flavour, acidity, Fat and SNF (solid not fat) etc. Milk not conforming to the standards laid down is rejected straightaway.

The marvel of modern milk processing technology now takes over. The milk is standardized with the right proportion of fats and solids not fat. To make it a wholesome supplement for human needs.

The milk which is accepted is chilled to 4^o Celsius and stored in silos. Reconstituted milk, when necessary, is added to augment the volume.
 

 Phosphatase tests

Like any other agricultural commodity, there are regional and seasonal imbalances in the production of milk also. In flush season and in milk surplus areas, when excess milk is available, it is converted to Skim Milk Powder (SMP) and Butter Fat and then stored. During the lean seasons and in milk deficit areas, when the availability of fresh milk is low, to augment supply, SMP and Butter Fat are recombined without jeopardizing the goodness and nutritive value of milk.

After chilling, the milk from the silos undergoes clarification, homogenization and pasteurization. Milk is passed through the clarifier at 40^o Celsius so that all extraneous matters are separated and removed from the milk.

Homogenization is carried out at a temperature of 70^o Celsius. It is a process by which fat globules in the milk, which have a natural size of 8-12 microns are broken down into much smaller sizes of less than 2 microns and evenly distributed throughout the milk. This reduces the tendency of fat to separate at and float the surface as a cream layer. This process also makes the milk more easily digestible.

The milk is pasteurized at 80^o Celsius to destroy pathogenic bacteria.

Finally, the milk is chilled to 4^o Celsius and stored. The milk is now ready for travel to thousands of waiting consumers.

Just prior to dispatch, the milk is glycol chilled to about 2^o Celsius and either automatically packed in polyethylene pouches or loaded in Mother Dairy’s fleet of Insulated road milk tankers to be delivered at the various distribution points.
