Castor seed oil extraction machine instruction:
a. Cleaning device:remove the raw material peanut in various impurities, such as: iron,
stones, clump, such as the plant leaf, clean up till impurity content does not exceed 0.2%.
b.Crushing machine: peanut is crushed into 6-8 pieces. In order to meet the requirements
of crushing, the peanut is suitable for crushing with the moisture of 7% to 12%.
c. Softening process:the purpose of softening is to adjust the moisture and temperature
of oil, and make it soft.
d.Flaking process: rolling raw material into flakes, and the purpose is to increae surface
area, destroy the peanut cell tissue, shorten the way of oil out from cake.
e:Extrusion: use steam and pressure to make flaks into porous pellets.
Extraction process:
1. Solvent pumps: continuously spray solvent to the rotary-type extractor
2. Roary extractor: Spray and soak the pre-pressed cake with solvent so that oil fats can be diss-olved 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 , then add saline
water to it. The phospholipid 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: to cooling the solvent gas separated from the wet meal and miscella for recycling.
