Milk Powder Plant

Milk powder is made from fresh, pasteurized skimmed milk. Milk powder manufacturing is a simple process which involves gentle removing of the water under stringent hygiene conditions while retaining all the desirable natural properties of the milk like Color, Flavor, Solubility and Nutrition Value.

 

Process Description:

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 °C and 120 °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 client’s 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 °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.
