Components of the milking machine

To understand how you can tell apart the qualities of the best milking machine, we should begin by dissecting the machine to know the features to focus on.

A milking machine consists of several basic component groups that work together for an effective operation. They include:

  • Milking units
  • Vacuum production and control system
  • Milk transport system
  • Cleaning and sanitation systems

Milk Cooling and storage systems are very instrumental accessories to the milking machine, as they will enhance quality preservation. However, they are not necessary for the functionality of the milking machine.

All the parts complement each other for the functionality of the machine. The milking unit does the actual extraction of milk from the teats.

The milking unit on its own also consists of several parts that enables it to imitate the hand to extract milk. Let’s have a closer look to understand how it works.

The milking unit has several parts including:

  1. Four teat cups for cows (and two for goats, sheep, etc.). Each of the teat cups has a soft rubber liner mounting on the metal or plastic shell; this rubber lining is the only part of the machine that comes into contact with the udder.
  2. The claw, which collects milk from all of the teat cups
  3. Pulsation chamber. The pulsator uses air and vacuum to create pulsation, which creates suction force to draw milk from the teats. 
  4. Connecting tubes for both air and milk.

The other supplementary components include regulators, balance tanks, and sanitary traps. They facilitate efficient operation of the milking unit and will help you produce clean and hygienic milk.

Care & Maintenance of Portable Milking Machines

Understanding how the milking machine works requires a close attention of what happens at the teat cup. The teat cup has the pulsator side and the milking side. These two are separated by a membrane that ‘pulsates’ to create a suction at the teat end.

Inserting the teat into the teat cup fills the cup camber. When you switch the machine on, it creates a vacuum in the chamber. This vacuum causes milk to flow from the teat.

During the rest phase, air enters the pulsator chamber and the increased pressure causes the liner to collapse around the teat. This creates a massaging effect on the teats to promote blood flow and prevents injury to the teat end.

The necessity for pulsation

  • Leaving the vacuum constantly on the teat for extended periods would lead to accumulation of blood and lymph at the end of the teat, stressing the teat and probably causing injury to the teat.
  • Pulsation ensures that there is blood circulation at the end of the teat to maintain teat end health.

An animation of how the milking unit of the best portable milking machine works:

Different milking machines have different pulsation ratios but they are typically going for 60 pulses every minute. The ratios sum up to 100 percent no matter the combination.

Pulsator working ratios

Most pulsator ratios range between 50/50 and 70/30 combinations. In this ratio, the first number represents the number of times the pulsator draws milk while the second number is the number of times the atmospheric pressure massages the teat.

You can vary the working ratios to suit your operations. Here is an overview of the ratios and what they mean:

  1. The ratio 60/40 is the most preferred ratio for optimal operation of the milking machine. You have moderate vacuum and pulsation, which does not stress the teats because you finish milking quickly.
  2. Anything that goes beyond 70/30 is not advisable, as it would cause injury to the animal due to too much sucking of the teats.
  3. Below 50/50 and the machine will not generate enough suction to extract milk.

Some machines have dual pulsation, which allows for different ratios for hind and front quarters. 50/50 and 60/40 for front and hind quarters respectively, are preferred because the hind quarters hold more milk than the front quarters due to their larger sizes.

Test for the suction force on the teats and adjust to comfortable levels

  • To test for the level of comfort on the teat, you can put your finger into the cup for about 20 seconds. The effect you feel is what the cows feel on the teats. If it is uncomfortable, you should adjust appropriately to comfortable levels.
  • With time, you will notice the different sounds that can tell you of any machine malfunctions. Replace parts as soon as you notice air holes (or bleed holes) as they end up in “bathing up” of the teats, which increases the chances of milk contamination.

There is no way we’re going to wind up this article without talking about the advantages and disadvantages of milking machines.

Advantages of using the best portable milking machine at your farm:

  • Reduces labor costs in large herds, as only a fraction of the human resources will be needed.
  • It is faster and can handle large volumes more efficiently than manual labor.
  • Milking machines reduce the farm’s dependency on manual labor, which can be very beneficial if you have turnover issues.
  • Using the best milking machine will reduce the stress on the animals and improve their health.
  • Milking machines can act as a quality assurance check for the dairy harvest.
  • The best portable milking machine can facilitate remote milking of the animals in the grazing fields.

Disadvantages of milking machines:

  • Your older animals may take some time to get used to the machine. During this time, you may experience a temporary drop in productivity.
  • The machinery is power dependent, so, you will not be able to milk during blackouts if you don’t have a backup. Emergency power supply and technical staff to operate the machinery will drive up your production costs.
  • The machines increase the risk of spreading udder infection among the herd. Milk sick cows last and separate their milk from the bulk; use teat dips immediately after milking. Wash and sanitize the milking machine immediately after use.
  • Maintaining the machines may not be very cheap and some of the parts for the older models may not be readily available.

By following the maintenance procedure shared previously, you will be able to eliminate these disadvantages and prolong the service term of your best portable milking machine.
