Cow Milking Machine

Innovations have modernized agriculture so that farmers are more productive than ever. For example, when I was a child, one farmer could feed or clothe about 70 people. Now, a farmer can feed or clothe about 200 people.

The dairy industry is no exception to the rule of innovation. Cow milking machines and other dairy equipment have greatly aided dairy farmer’s productivity.

After my family had been milking cattle for several years by hand, we put in a full time dairy. In order to do this, we modernized an old dairy barn with new equipment and added milk cows to our herd.

The dairy barn had an old stanchion system that we used to hold the cattle. It could hold five cows at one time. Their heads were held over a feed trough were they ate while they were washed and then milked.

Our milking system had two cow milking machines. So, we would wash one cow, attach the milker, then repeat on another cow. While they milked, we washed the other 3 cows.

The cow milking machines operated on a vacuum system. They attached to a glass line by large flexible tubing. The glass line drove the milk via the vacuum to the milk room.

Smaller flexible tubing attached to the cow milking machines. These provided the “pulsator,” or rythmic squeezing that simulated the squeeze of a hand. They pulsator vacuum was housed in a separate chamber of the cow milking machine.

Once the milk made it to the milk room, it would enter a bowl, or large glass container that drained through a strainer into the milk cooling tank. The bowl had electrodes in it so that when the milk rose high enough, it would activate a pump that would drive the milk on through the strainer into the milk tank.

The entire system was powered by a vacuum motor. The line had a “reserve tank” on it that would help alleviate stress from the motor.
