How is Powdered Milk Made?
The production of powdered milk involves several key steps aimed at maintaining the quality of the milk throughout the process. Understanding these steps sheds light on whether powdered milk can genuinely be considered “real milk.”
The Process of Making Powdered Milk
Collection and Pasteurization:
The first step involves collecting fresh milk from dairy farms. This milk is then pasteurized to kill harmful bacteria, ensuring safety for consumption.Evaporation:
After pasteurization, the milk undergoes evaporation, wherein water is removed under low-pressure conditions. This process concentrates the milk, resulting in a thick liquid.Drying:
The concentrated milk is then dried using methods such as spray-drying or drum-drying. In spray-drying, hot air is used to atomize the liquid into tiny droplets, quickly evaporating the water. Drum-drying involves spreading the liquid onto heated drum surfaces, forming a powder as it dries.Cooling and Packaging:
Once dried, the milk powder is cooled to room temperature to prevent clumping. It is then packaged in moisture-proof containers to maintain freshness.
