There are four parts of a cooking oil solvent extraction workshop: solvent extractor, D.T.D.C system, evaporator & stripping tower, condenser. Among them, the solvent extractor is the main part. Except for rotocel extractor, there also are two kinds of solvent extractor: chain extractor and loop type extractor. But the most common-used type is rotocel extractor.
Three types of solvent extractor used in cooking oil solvent extraction workshop
The rotocel extractor is suitable for the small capacity cooking oil solvent extraction workshop, less than 300tons/day. The cost of the rotocel extractor is lowest among these three kinds of solvent extractors, but it is not suitable for the big capacity cooking oil solvent extraction workshop, more than 500tons/day. Besides, because rotocel extractor has smaller size than loop type solvent extractor, it needs smaller workshop, which makes the cost of building workshop is lower than other two types.
The 60tpd palm kernel oil solvent extraction plant project is installated in Nigeria, using the rotocel extractor
In solvent extractor, the oil in the cakes will be extracted out by solvent. The most common-used organic solvent is n-hexane. Through spraying n-hexane, the cakes are soaked in the solvent for a certain period of time. After this, you will get two parts: wet meal and miscella.
The wet meal will go to D.T.D.C system to be evaporated, and then the solvent in it will be removed. At last you will get dry meal, which includes less than 1% residual oil and is very suitable as animal feed. The miscella will go to evaporator and stripping tower to remove the solvent to get the crude vegetable oil. Finally the solvent will be recovered by condenser.
So different solvent extractor has different technology and is suitable for the different capacities cooking oil solvent extraction workshop. You need tell us your requirements, raw materials, budget and other information, and then our engineer will design the most suitable proposal for you. Henan Doing Company will provide you the best service.
