Cottonseed oil is a vegetable oil extracted from the seeds of the cotton plant after the cotton lint has been removed. It’s composed of linters (10%), cotton shell (40~45%) and kernel. the oil content of cotton seed is 15%-25%, the oil content of kernel is 30%-40% after decorticating.
How is cotton seed oil produced?
The production of cottonseed oil has 3 methods: mechanical screw oil pressing, pre-pressing & solvent extraction, and direct solvent extraction. Cotton seed oil pressing mainly rose in 1960s when cottonseed oil was pressed by small batch type cold oil press machine and sold in the form of crude oil.
How to extract oil from cottonseeds?
If your cottonseeds are with lint, then you need to add cottonseed delinting machine in the cottonseed oil plant. Oil extraction is using the organic solvent to extract oil from the pre-pressed cake inside the oil extractor.
What is cottonseed oil processing technology?
The latest progress of cottonseed oil processing technology is the use of the extruder. The extruded material then goes through solvent extraction, which simplifies processing technology, and reduces the loss of solvent, reduces residual oil in meal, and improves the feeding property of cottonseed meal.
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.
How a cottonseed oil plant can achieve 500 t/d?
The combination use of the cottonseed extrusion, oil extraction and the mixed oil refining process can make the production of our cottonseed oil plant reach 500 t/d. The extrusion & extraction technology can improve the oil yield and reduce the solvent loss.
