The diagram given delineates the multi-stage process of manufacturing yogurt.
Looking from an overall perspective, it is readily apparent that this man-made procedure includes four distinct stages, commencing with mixing four ingredients, followed by exposing the mixture to different temperatures, and ending with packaging to be sold.
In the first stages, 4 ingredients including milk, sugar, dry milk, and stabilizers are put into a hygienic stainless steel vessel. Subsequently, the mixture is heated to 85 degrees Celsius and starts the pasteurization before beginning the homogenization (when the mix is cooled to 42 degrees Celcius).
Looking at the next stages in detail, the mixture is stirred while the cultures are poured into it. After the blend decreases to 7 degrees Celsius, it goes through to the fermentation process. Eventually, the completed product called yogurt is packaged before selling to the customers.
