What is the name of the machine that was invented to remove cotton seed from fiber?

The machine that was invented specifically to remove cotton seeds from the fiber is known as the cotton gin. This invention revolutionized the cotton industry by making the process of separating the seeds from the cotton fibers much more efficient than manual methods. The cotton gin is designed to handle and separate large quantities of cotton quickly, significantly increasing production speed and reducing the cost of processing.

The importance of the cotton gin lies in its impact on the cotton industry and agriculture as a whole. By automating the seed-removal process, it allowed for greater profitability for cotton farmers and contributed to the growth of the cotton economy in the United States during the 19th century.

Other options like a seed picker and harvesting machine are related to agricultural practices but serve different purposes. A seed picker typically refers to equipment used for collecting seeds from the field, while a harvesting machine is designed for gathering crops in general. A fiber separator might suggest a similar function to the cotton gin but does not refer specifically to the historical and technological significance of the machine used for cotton processing.
