       The principal function of the cotton gin is to separate lint from seed, but the gin must also be equipped to remove foreign matter, moisture, and other contaminants that significantly reduce the value of the ginned lint. Gins must produce a quality of lint that brings the grower maximum value while meeting the demands of the spinner and consumer. Operating gin machinery in accordance with the recommended speeds, adjustments, maintenance, and throughput rates will produce the highest possible fiber quality. A standardized sequence that includes dryers to obtain the proper moisture level as well as machines to remove the foreign matter is recommended for processing cotton at the gin.
