Cows are milked in a place called a milking parlour. The milking machine is made up of a four teat cup and a vacuum pump. The cow's udder and the machines must be cleaned before they are used. The farmer then gently connects the milking machine to the teats. The milk is sent to a big storage tank ( like a big fridge) where it is refrigerated before being transferred to the tanker truck.
Once the cow has been milked she returns to the barn to eat and walk around.
At the creamery the milk is pumped into huge refrigerated storage tanks. The milk is them pumped into a machine called a pasteuriser. Here the milk is heater for 15 seconds then cooled again quickly. This is a way of cleaning the milk and making sure any harmful germs or bacteria in the milk are killed.
After the milk is cleaned it is pumped into smaller tanks where bottles and cartons of milk are filled. Once the cartons are filled lorries carry the milk to shops all over Ireland to be sold to people like you and me.
Milk is also used to make other foods in the creamery. In Monaghan the creamery produces yoghurts, butter and cream. These are all called dairy products.
