Various stages in the process of commercial production of yogurt are sequenced in the given diagram.
Overall, it is clear that this seven step process starts with the heating of milk and ends with the distribution of yogurt packets to various destinations.
In the first step, milk is heated in a vessel to a temperature of 90⁰C for about half an hour. The more time the milk remains in the vessel at this regulated temperature, the thicker the yogurt becomes. In the second step, the temperature of this milk is brought down to 44⁰C, and once this temperature is attained, live bacteria is inoculated into the milk.
In the subsequent step, the temperature of the milk in the vessel is allowed to fall further to the room temperature and simultaneously, the mixture is kept undisturbed for around four hours. After this stationary period, it is refrigerated and in the penultimate step, sugar and flavours are added. In the final step, the obtained yogurt is packed in air-tight containers and dispatched to various destinations.
