1. Introduction of sesame oil extraction machine
1) Function: sesame oil extraction machine is an oil extractor 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: sesame oil extraction machine fits for pre-press extraction of high-oil- content materials
and direct once time extraction of low-oil-content materials.
3) Main parts: sesame oil extraction machine series includes rotary extractor, toaster, 1st evaporator,
2nd evaporator, stripping tower, condenser, etc.
2. Main parts of sesame oil extraction machine
1) Solvent pumps: continuously spray solvent to the rotary-type extractor.
2) Rotary 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: used to separate the solvent from the wet meal.
4) Miscella tank 1st: pump the miscella (oil with solvent) into the miscella 1st, then add 10% saline water to
it. The phospholipids and impurities in the miscella will react with the saline water, 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.
3. Main Process of sesame oil extraction machine
1) The material (for pretreatment) is sent to rotary extraction by the scraper conveyor. The material will
extracted by the solvent or mix oil. After this step, we will get meal and mix oil.
2) Meal is send to toaster. Through the toaster, the solvent in the meal will separate from the meal. The
solvent goes to condenser and is recycled to rotary extraction.
3) After the mix oil from the rotary extraction enters into 1st evaporator and 2nd evaporator, most of the
solvent in the mix oil is separated.
4) The mix oil from 2nd evaporator goes to stripping tower and almost all the solvent is separated. From
the stripping tower, we can get crude oil and solvent. The solvent is sent to condenser and is recycled to
rotary extraction.
4. Advantages of sesame oil extraction machine
1) High oil yield, obvious economic benefit.
2) Less residual oil rate in the dry meal.
3) Improving the quality of the meal.
4) Low processing cost, high labor productivity.
The oil quality outcome standard:
1. Grade one for salad oil
2. Grade two for high quality cooking oil
3. Mixture and volatile less than 0.25%
4. Impurity less than 0.2%.
5. AV (mgKOH/g) less than 7
6. FFA less than 3.5%
