Separation:The
raw milk is separated in to skimmed milk and cream using a
centrifugal separator. If the extra fat is required in the milk
powder then some cream is added back to the skimmed milk.

Pasteurization:The
skimmed is preheated to temperatures between 75 A a A A C and 120
A a A A C and held for specified time from a few seconds up to
several minutes. Preheating causes a controlled denaturation of the
whey proteins in the milk and it destroys bacteria, inactive
enzymes, generates natural antioxidants and imparts heat stability.
The pasteurized milk can be directly converted in to powder as per
clientA AcAca A Aca Acs requirement.

Evaporation:In
the evaporator pasteurized feed is concentrated in multiple effects
from around 9.0% total solids contents up to 45-52% total solid
contents. For this feed is boiled under vacuum at temperature below
72 A a A A C which removes he water vapors.

Spray
Drying:The concentrated milk (Skimmed Milk) is then dried to powder
form in a spray dryer. The feed is atomized to fine droplets in a
large spray chamber by using either disc atomizer or series of high
pressure nozzles. These atomized particles come in contact with hot
air and water in it gets evaporated. The feed droplet temperature
never reaches the temperature of hot air as it is cooled by
evaporative cooling. The dried product is discharge at the bottom of
chamber and if required it is passed through instantiser. An
instantiser consists of a fluid bed dryer cum cooler. The dried
product entrained with the exhaust air is separated in a high
efficiency cyclone separator and recycled back to the chamber. The
exhaust air is further passed through a wet ventury scrubber for
recovering the fines not separated in cyclone. Clean air is then
vented to the atmosphere the process air is handled by means of two
centrifugal fans. The entire operation of the plant is monitored and
controlled through a locally mounted control panel or PLC.
