An Introduction to what they are, how they work, and their partsMilking Machines An Introduction to what they are, how they work, and their parts © MilkTech International
What is a Milking Machine?A machine for harvesting milk from the udders of cows, goats, bison, sheep or animals. © MilkTech International
Milk Harvesting Milk harvesting is the process ofextracting milk from animals Transporting the milk to a storage tank Storing the milk until it is picked up for processing. Milk is usually cooled during storage Milk harvest requires cooperative effort between : The animal and The operator And a properly functioning milking machine © MilkTech International
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 health Not degrade milk quality from the time of removal to delivery Be easy to clean and sanitize © MilkTech International
Milking Machine ComponentsA milking machine is made up of several basic component groups Milking units Vacuum production and control system Milk transport system Cleaning 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 © MilkTech International
Lets start with the big picture and see how these components fit togetherNot a good example for NZ or Australia. Better to have a typical herringbone. © MilkTech International
Lets have a closer look at the milking unitThe 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 teatcups The 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 © MilkTech International
Lets see how we get milk out of a cowVacuum is applied to the inside of the liner to withdraw milk from each teat and keep the machine attached to the cow When the pulsation chamber is under a vacuum, the liner is open and milk flow starts Atmospheric pressure is the applied to the pulsation chamber and the liner closes. Milk flow stops and the teat is massaged to reduce congestion Too many words, and too complicated. Remember KISS, and the target audience – people who may not have had any prior contact with milking and milking machines. © MilkTech International
Lets look at how air and milk move through the machineBlue= Air Red= Milk Violet= Air+Milk Too much info on one slide. Milk and Air flowing from the receiver into the sanitary trap presents a few problems! Need to mention variable speed vacuum pump drives as well as regulators. © MilkTech International
So here we are back at the start. QUIZ TIME!!!Q: What is a Milking Machine? A: A machine for harvesting milk from the udders of cows, goats, bison, sheep or animals. © MilkTech International
