Seed-cotton storage

The technology with which cotton is now processed between the field and the mill was developed before the energy crisis, before OSHA, before EPA, before wage-and-hour laws, before open-end -spinning, before electronic data processing and before economical seed-cotton storage. That is to say that it predates factors that cause the need for advances, but it also predates the technology that will eventually lead to advances that permit cotton to meet the needs of the modern textile trade. 

Because the gin capacity is usually not sufficient to keep up with the harvesters, the harvested cotton is often stored in a compacted module and ginned at a later date. The type of storage or seed cotton processing may place additional constraints on the harvest process. If the seed cotton is to be placed in module storage, the cotton should not be harvested until the moisture content is 12% or less and the harvested seed cotton should be free of green plant material such as leaves and grass. 

After harvesting, the seed cotton (consisting of cotton fiber attached to cottonseed and plant foreign matter), a raw perishable commodity, is transported to the ginning plant in trailers or modules, or is stored in the field in modules. In the United States, module storage is used for almost the entire crop. Field storage in modules maximizes efficiency at the gin. 

Cottonseed Oil (Unhydrogenated) occurs as a dark red-brown oil. It is obtained from the seed of the cotton plant Gossypium hirsutum (American) or Gossypium barbadense (Egyptian) by mechanical expression or solvent extraction. It is refined, bleached, and deodorized to substantially remove free fatty acids, phospholipids, color, odor and flavor components, and miscellaneous other non-oil materials. It is liquid at 21° to 27°, clouds at 21°, and partially solidifies at storage temperatures... 

Othors. Triacylglycerols (triglycerides) (10) (70-72) make up a large part of the storage lipids in animal and plant cells. They are now receiving renewed attention as a candidate feedstock for the production of polymer resins. When liquid at room temperature they are called oils. Commercially important oils are produced from the seeds of soybeans, com (maize), cotton, sunflowers, flax (linseed), rape, castor beans, tung, palms, peanuts, olives, almonds, coconuts, and canola. Over 7.3 million metric tons of vegetable oils are produced in the United States each year, mainly from soybean, flax, and rapeseed. Soy oil alone accounts for 80% of the seed oils produced in the United States. Soy oil contains about 55% linoleic acid (11), 22% oleic acid (12) and 10% palmitic acid (13).
