[5] The August 1931 issue of the American Journal of Public Health and the Nation's Health described the Rotolactor as an advance in cleanliness and hygiene for milk production. [5]
One year later, in 1869, Baldwin designed two new inventions, one was an improved milk separator and the other was an improved milk cooler. Baldwin would later reissue a patent for her milk cooler to implement some improvements to her design in 1871.

The milking process is the collection of tasks specifically devoted to extracting milk from an animal (rather than the broader field of dairy animal husbandry).This process may be broken down into several sub-tasks: collecting animals before milking, routing animals into the parlour, inspection and cleaning of teats, attachment of milking equipment to teats, and often massaging the back of the ...
In small dairy farms with less than 100 cows, goats or sheep, the pipeline is installed above the animals' stalls and they are then are milked in sequence by moving down the row of stalls. The milking machine is a lightweight transportable hose assembly which is plugged into sealed access ports along the pipeline.
The milk is filtered and cooled before being added to a large bulk tank of milk for storage. [3] The average time of milking is 5–7 minutes and a cow can be milked with a machine 2–3 times a day. [4] The existing robotic milking has allowed cows to have the freedom to decide when to milk, but still needs to make contact with people. [5] [6]
Methane expelled by livestock belching and farting contributes about 15% of global emissions each year, UN estimates show. It is the most common greenhouse gas after carbon dioxide (CO2).
Cow Milk Production by State in 2016 After a brief rise following the Great Recession of 2008-9, milk prices crashed again in the late 2010s to well under $3 a gallon at major grocers in the United States. Pennsylvania has 8,500 farms with 555,000 dairy cows. Milk produced in Pennsylvania yields an annual revenue of about US$1.5 billion. [70]
