Jinan LD soya oil extraction machine brief introduction:
a. Cleaning device for Soybean Oil Plant:remove the raw material soybean 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 for Soybean Oil Plant: soybean is crushed into 6-8 pieces. In order to meet the requirements
of crushing, the soybean is suitable for crushing with the moisture of 7% to 12%.
c. Softening process for Soybean Oil Plant:the purpose of softening is to adjust the moisture and temperature of oil, and make it soft.
d.Flaking process for Soybean Oil Plant: rolling raw material into flakes, and the purpose is to increae surface
area, destroy the soybean cell tissue, shorten the way of oil out from cake.
e:Extrusion for Soybean Oil Plant:through high temperature and high pressure, soybean flakes are transfered into expanded pellet, which is easy to extract oil from, and keep high nutritive value.
Jinan LD soya oil extraction machine Extraction process:
1. Solvent pumps for Jinan LD soya oil extraction machine: 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 for Jinan LD soya oil extraction machine: usd to separate the solvent from the wet meal.
4. Miscella tank 1st evaporation for Jinan LD soya oil extraction machine: 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 evaporation for Jinan LD soya oil extraction machine: the purified miscella will be pumped into it, and use high temperature steam to let solvent evaporate out.
6. Miscella stripping for Jinan LD soya oil extraction machine: it will remove the remaining solvent in miscella. And the solvent will be discharged to condenser for recycling.
7. Condensers for Jinan LD soya oil extraction machine: to cooling the solvent gas separated from the wet meal and miscella for recycling.
