Process Lines > Spray Drying Milk Products
Drying extends the shelf life of milk apart from reducing the weight and volume. Drying lowers the cost of transportation also.

The initial solid in the milk varies from 7.5% to 12% depending upon type of milk and the final moisture in the powder ranges between 2.5% and 4%.
Since drying is an energy intensive process. Following operational plants are used to make it energy efficient:

Multistage Evaporator
Spray Dryer
Vibro Fluid Bed Dryer as second stage dryer
In multistage evaporator initially milk is concentrated up to 48%. Five stage evaporator with TVR suction from 3rd effect gives specific steam consumption as low as 0.12 kg/kg water evaporation.

During drying in spray dryer, the excess water present in free form between the particles of the dry solids get evaporated easily. Whereas last stage of evaporation demands more energy as water contained in pores and capillaries of the solid particles need to be evaporated.

These last drops of water are removed in a vibro fluid bed dryer which requires less energy for removal of balance moisture.

The combination of multistage evaporator, spray dryer with fines recirculation system and use of a 'Vibro Fluid Bed Dryer', produces powder with extremely good solubility called instant powder.

We ensure that not only the production of instant powder of highest quality from their plants but also most energy efficient plant.
