Tools, equipment and machinery used for milking a cow

Milking machine: The milking machine is a system consisting out of varies parts that work in combination with each other to milk a number of cows at the same time. The following parts form the basic framework of the milking machine.
• Claw;
• Teatcups;
• Milk tubes (many different shapes and sizes);
• Pulsator;
• Bulk tank

Milking machines are used to extract milk from cows when the herd is larger than about 4 cows. The milking unit is the portion of a milking machine for removing milk from an udder. It is made up of a claw, four teatcups, long milk tube, long pulsator tube, and pulsator.

The claw is manifold which connects the short pulse tubes and short milk tubes from

The two rigid, stainless steel teatcup shells applied to the front two quarters of the cow are visible. The top of the flexible liner is visible at the top of the shells as are the short milk tubes and short pulsation tubes extending from the bottom of the shells to the claw.

The bottom of the claw is transparent to allow visualization of milk flow.

When milking is completed the vacuum to the milking unit is shut off and the teatcups are removed
Milking machines keep the milk enclosed and safe from external contamination. The interior 'milk contact' surfaces of the machine are kept clean by a manual or automated washing procedure implemented after milking is completed twice or three times per day.

Milk contact surfaces must comply with regulations ensuring that they are food grade materials (typically stainless steel and special plastics and rubber compounds) and are easily cleaned.

Most milking machines are powered by electricity but, in case of electrical failure, there can be an alternative means of motive power, often an internal combustion engine, for the vacuum and milk pumps because milking cows cannot tolerate delays in their scheduled milking without suffering serious milk production
