Processing cottonseed with a combination of extrusion cooking and Expeller® pressing can reduce oil residuals to less than 6% while minimizing toxins. One ton of crushed cottonseed yields about 45% meal, 27% hull, 16% crude oil, and 8% linters.
How is cottonseed processed after extrusion?
After extrusion, cottonseed can be fed into a screw press like the Anderson Oil Expeller®, which uses physical force to separate the oil from the solid meal. Processing cottonseed with a combination of extrusion cooking and Expeller® pressing can reduce oil residuals to less than 6% while minimizing toxins.
How does a cottonseed oil extraction plant work?
The wastewater is discharged into the water seal tank. The vent gas in the cottonseed oil extraction plant enters the mineral oil system for further recovery of solvent. Solvent recovery can reduce solvent consumption and ensure safe production. 1. Degumming Phospholipids are easy to adsorb bleaching clay and reduce bleaching effect.
When did cottonseed oil come out?
America¡¯s first cottonseed oil mills opened in the 1830s, and by 1850, U.S. cotton production grew to nearly 3 million bales a year. The seed¡¯s oil had become the primary source of vegetable oil in the country by 1890, and by 1900, the U.S. was crushing more than 2 million tons of cottonseed.
