Vegetavble oil solvent extraction machine introduction:
Solvent extraction is a method for separating a substance from one or more others by using a solvent.The purpose of cooking 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.

Method of vegetable oil extraction process
1) The material will be have a pretreatment process , we need to clean the oilseeds, crush , cook , flaking , press the rapeseed . the oil residue in the cake is about 7-8 % .this oilseeds press method is suitable for small capacity ,not large .
2) The method is pre -press and solvent extraction method .It means we press the oilseeds first,then the oil residue left is about 12-13% in the cake .Then we send the cake to extractor to leah the oil from the cake ,which make sure the oil residue is about 1%.This method is for larger capacity ,and the invest is a little big .
Different types of vegetable oil extractor
Introduction of vegetable oil solvent extraction machine:
1) Function of vegetable oil solvent extraction machine: Leaching system is an oil extraction through soaking or spraying pre-pressed cake by a certain organic solvent. The principle of this part is the different solubility of solvent.
2) Use range: Solvent extraction fits for pre-press extraction of high-oil-content materials and direct once time extraction of low-oil-content materials.
3) Main parts of vegetable oil solvent extraction machine: The extraction series includes rotary extractor, toaster, 1st evaporator, 2nd evaporator, stripping tower, condenser, etc.
Main parts of vegetable oil solvent extraction machine :
(1)Solvent pumps: continuously spray solvent to the rotary-type extractor
(2).Rotocel extractor: Spray and soak the pre-pressed cake with solvent so that oil fats can be dissolved in solvent(form miscella). After processing, you can get wet meal and miscella (mixed oil).
(3). DTDC: usd to separate the solvent from the wet meal.
(4). Miscella tank 1st: pump the miscella (oil with solvent) in to the miscella 1st , and then add 10% saline water to it.
The phospholipid and impurities in the miscella will react with the saline wter, at last the reactant precipitate, reaching the goal of purifying.
(5). Miscella tank 2nd: the purified miscella will be pumped into it.
(6). Miscella stripping: it will remove the remaining solvent in miscella. And the solvent will be discharged to condenser for recycling.
(7). condensers: used to cooling the solvent gas separated from the wet meal and miscella for recycling.
