The diagram shows how milk is produced.
Overall, it is clear that the process of milk production consists mainly of nine distinct stages, beginning from cows grazing to ending when milk is produced and ready for sale.
Looking more closely at the given diagram, we can see that the process of milk production begins with cow grazing on the grass. The cows are milked by a milking machine twice a day. Then, the milk is sent for refrigerated storage. After that, the milk is transferred to a tanker and transported by daily delivery to Dairy.
At the next stage in the process of production, the milk is separated into two. First, milk is pasteurized and packaged. Second, cheese, cream and butter are made from milk. Finally, this packaged milk is sent to supermarkets and shops for sale.
