When was the milking machine invented

The first surge milker would sit on the ground under the cow and a later model shown below of the surge milker hung from the cow by a strap that went around its body. An advantage to the hanging model was that the tubing from the teat to the bucket was only about 4 inches long, which lessened the rick of contamination within the tube. Machines that saw on the ground had longer tubes from the teat to the milk container which were hard to clean thoroughly.

Another advantage to shorter tubing was that when the cow was finished milking and the tubes automatically fell off, they would not hit the ground and pick up dirt like the early surge milk machine. There are three common types of modern milking parlors: parallel, herringbone, and rotary milking parlors. The parallel parlor shown below has two rows of stalls on each side of the working area.

The cows are perpendicular to the farmer and the suction tubes are placed on the cow from directly behind. It looks very similar to the herringbone. The herringbone parlor shown below looks similar to the paralell above. The main difference between the two is that with the herringbone, the cows are at an angle, and the suction tubes are placed on the teats from the side of the cow.

Throughout the process, many steps are taken to make sure that the milk is kept safe and clean. Samples are tested continuously to make sure the milk is safe. All machinery, barns, and milking equipment must be kept clean as well. A top priority for dairy farmers is the health of the animal. Sick or poorly cared for cows will not produce quality milk.

This includes keeping the areas where the cows live and are milked clean. If a cow is sick, the vet may give it medicine and then that cow, and its milk, is kept separate from the others until the cow is healthy again. Farmers may choose to use pastures, open-sided barns, or open lots with shade as places to raise their cows.

In barns, dairy cows have the ability to move around, as well as eat, drink, and lie down. In order to give milk, a cow must have given birth to a calf. The cow is pregnant for about 9 months before giving birth to the calf. That is about the same amount of time it takes a baby human to be born. The cow must be milked at least twice per day. In some cases, a cow is milked 3 or more times per day. The udder is divided into four parts.

Each part has a teat, or nipple. If the nipple is squeezed, and there is milk in that part of the udder, the milk will come out. Then the farmer will either begin to milk the cow by hand, or attach a milking machine, which gently squeezes the milk out of the udder. Systems were introduced in the s that almost completely removed people from the milking process.

For a step by step look at the process of automated milking machines, take a look at this article published in June , featuring the Stensland Family Farms near Larchwood, Iowa. The farmers shared their experiences using automated milking machines, and the impact these machines have made on the farm and the cows. Today, when a milking machine is used, the milk goes from the cow through the milking machine to pipes that take the milk to a bulk tank, where it is stored.

No human hands will have touched the milk. Refrigerated trucks stop by most dairy farms on a daily basis to pick up the milk and take it to a creamery. The milk trucks are tested to make sure that they are clean and able to move milk safely.

Some dairy farms have creameries on the farm, so they do not need to transport milk off of the farm in this way. Food, or agricultural, processors take raw ingredients and make them into different types of food that people can eat. For example, a creamery will process milk to make cheese or butter or chocolate milk.

Most of the time, processing is done off of the farm. But some farmers in Iowa have creameries on their farm that they can use to process the milk on the farm.

At the processor, before the milk is taken off of the truck, it is tested to make sure it is still safe. Then it goes through a three-step process: standardization, pasteurization, and homogenization. Then the milk can be bottled, or made into other products, such as butter, ice cream, and yogurt.
