Milking Machines

An Introduction to what they are, how they work, and their parts


What is a Milking Machine?

A machine for harvesting milk from the udders of cows, goats, bison, sheep or animals.


Milk Harvesting

Milk harvesting is the process of extracting milk from animalsTransporting the milk to a storage tankStoring the milk until it is picked up for processing. Milk is usually cooled during storage

Milk harvest requires cooperative effort between :

The animal andThe operator

And a properly functioning milking machine


Milking Machine Goals

A properly designed, installed, maintained, and operated milking machine will:

Remove milk from the animal quickly and gently Not contribute to poor udder healthNot degrade milk quality from the time of removal to delivery Be easy to clean and sanitize


Milking Machine Components

A milking machine is made up of several basic component groups

Milking unitsVacuum production and control systemMilk transport systemCleaning and sanitation systems

Milk Cooling and Storage systems Although not part of the milking machine itself, the milking machine always delivers milk to a storage container And milk is usually cooled on the farm


Lets start with the big picture and see how these components fit together


Lets have a closer look at the milking unit

The milking unit is made up of several parts

4 Teatcups (for cows) A soft rubber liner that is

mounted in a metal or plastic shell

The soft rubber liner is the only part of the machine that touches the udder

The claw Collect milk from all of the

teatcupsThe Pulsator

An air valve that creates ‘pulsation’ or the opening and closing of the liner

Connecting tubes Short milk tube = liner to claw Long milk tube = claw to

milkline Short pulse tube = shell to air

fork Long pulse tube = air fork to

pulsator


Lets see how we get milk out of a cow

Vacuum is applied to the inside of the liner to withdraw milk from each teat and keep the machine attached to the cowWhen the pulsation chamber is under a vacuum, the liner is open and milk flow startsAtmospheric pressure is the applied to the pulsation chamber and the liner closes. Milk flow stops and the teat is massaged to reduce congestion

Lets look at how air and milk move through the machine


So here we are back at the start.
