There are farmers that only hand milk their cows because they don’t need a machine, but there are machines that will do this for them.
They are very easy to use, despite how complex they look, and you can use them very easily. The objective is to hook up the cow to the machine and cause the milk to flow.
This is how it works:
On the apparatus are teat cups that are attached to the teats of the cow. There are those that are made of silicone, whereas others are made of rubber, and they almost always have a stainless steel shell. The liners, which are also part of the system, will touch the cow. They can form a seal, and this is between the short milk tube and the teat, which is also used to transport the milk when it is extracted. Liners are going to move because of what is called a pulsator valve. This can only move because of the vacuum pump. There is a shell, connected to the pulsation chamber, plus the liner on the system.
When the pulsator begins to function, it will cause the vacuum to open up the liner.
When this is on, there is a short milk tube that is going to provide constant section. The equalization of air pressure in between the vacuum, the short milk tube, and the pulsation chamber, will lead to the milk beginning to flow.
After the pulsator releases the vacuum, then the liner will be able to be exposed to the air once more. The air pressure in the pulsation chamber is going to be higher, especially when compared to the short milk tube, and this will lead to a massaging motion and the collapse of this on the teat. This is what allows proper blood circulation to flow during this process.
When the pulsator operates, it does so what about 60 cycles per minute.
There are short milk tubes, attached to teat cups, and if there are multiple ones this is part of the claw. This is how all of the milk can be extracted and mixed together.
The vacuum connected to the long milk tube will pull the milk through the line.
It will then flow through the long milk tube and will enter into the receiving jar. In many cases, trapped air pockets will be present, and these will be released. All of the other cows that have had milk extracted will have their milk mixed in with the others.
The receiving jar, at this point, will begin to fill up, and the pump will begin to push the milk into a larger tank where it can be kept at a cool temperature.
Once the udder has emptied, it will cause the machine to shut off. Meters will make sure that this occurs.
The teat cups, in the absence of the section, will fall from the teats of the cow.
Iodine is then used in order to prevent infection, specifically preventing any form of contamination going back into the teats when the pulsator let’s air into each teat cup.
Once done, the machine is properly cleaned.
In cases where there are smaller operators, they can do this a little differently, typically using some form of a bucket. The pulsator will be on top of the bucket. Once the process is over, it is removed, and all that you have left is fresh farm milk, due to this small milk pasteuriser.
How To Clean The Machine
Flushing is the best way to clean milking machines but it can be done in other ways. You can use a bucket, or a full-fledged flushing system that will use a vacuum to purge the entire apparatus. By doing this regularly, and also taking out clusters that will appear in the bucket, you can clean everything to the best of your ability.
