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 plant?
The cottonseed oil plant includes cottonseeds pretreatment and prepressing workshop, cottonseed cake solvent extraction workshop and crude cottonseed oil refinery plant. The residual oil rate in the cottonseed meal is lower than 1%. Cottonseeds contain a toxic pigment which called gossypol, of which the content is 0.15%-1.8%.
What is the history of cottonseed oil industry in India?
In India traditionally, the cottonseed utilisation has been as an animal feed and it was in 1914 that Indian Oil Company established the first cottonseed oil mill at Navsari. Since then the Indian cottonseed oil industry has come a long way. 1. Cotton Production (Lakh bales) 2. Cottonseed Production (@333Kg/bale) (Lakh tonnes) 3.
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.
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.
