Vegetable oil extraction production line production:
The vegetable oil solvent extraction machines are used where oil is extracted from oil seeds like soybean, sunflower, cottonseed, other oil seeds and oil cakes like mustard cake, groundnut cake and rice bran.
Solvent extraction is a method for separating a substance from one or more others by using a solvent.The purpose of vegetable oil solvent extraction machine is extract oil from the cake.This solvent extraction method is for larger capacity ,but the invest is a little big.
Cottonseed oil extraction plant adopts solvent extraction method to extract cottonseed oil The cottonseed oil plant includes cottonseeds pre-treatment and pre-pressing 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%. Cottonseed kernels contain 0.5%-2.5% of gossypol. After processed by the cottonseed oil refinery plant, the gossypol content in the oil is less than 0.01%. The products of the cottonseed oil processing plant are cottonseed oil, cottonseed meal, cottonseed hull, and soapstock.
Two methods about cotton seed oil extraction process plant:
1) The material will be have a pretreatment process , we need to clean the cotton seed, crush , cook , flaking , press the cottonseed .The oil residue in the cake is about 7-8 % .this oilseeds press method is suitable for small capacity ,not large .
2) The vegetable oil processing method is pre -press and solvent extraction method .We should press the oil seeds first,then the oil residue left is about 12-13% in the cake .Then we send the cake to cottonseed oil solvent extraction machine to leach the oil from the cake ,which make sure the oil residue is about 1%.This pre-press and solvent extraction method is for larger capacity ,and the invest is a little big .
You can choose different way to finish the oil extraction process depends on his capacity.
