The raw material seed after pre-treatment section can get oil and seed cakes,there are also oils in the cakes, then delivery the seed cakes to the edible oil solvent extraction process to extract residual edible oil.Edible oil solvent extraction process a major process in edible oil processing machine, which can extract out oil from oilseed using organic solvent. And edible oil solvent extraction machine used to extracting oil from the vegetable seeds, such as: soybean, peanut, sunflower seed, rapeseed,rice bran, corn germ, cottonseeds, etc.
Edible oil solvent extraction plant
The basic process of edible oil solvent extraction: Soaking embryo(puffing oilseed, prepress cake or embryo slice)into the selected solvent, makes edible oil dissolve in the solvent (miscella), then separate miscella and solid cake; Miscella evaporates and strip according to different boiling points, make solvent vaporize into steam, and seperate with oil, then get crude oil. Solvent steam can be recycling through condensation,cooling. The meal also contains some solvent, it will get dry meal after desolvent and drying, during this process, it will volatilize steam,also can be recyclable through condesation and cooling.
Edible oil solvent extraction process
The crude oil quality in edible oil solvent extraction process:
1.The total volatile matter of crude oil is less than 0.2%.
2.The meal oil residue rate is less than 1%(powdery meal is less than 2%), the moisture is less than 12%.
3. Crude oil stardand: color, smell and taste are normal; The moisture and volatile matter are 0.5%; Impurities 0.5%; The acid value is up to crude oil quality.
The consumption standard of edible oil solvent extraction projest:
1.1ton oilseed can consume steam less than 380g.
2. 1ton oilseed can consume electricity less than 15 kw
3.1ton oilseed can consume recycling cooling water less than 20 ton.
4.1ton oilseed can consume solvent less than 2kg
Edible oil solvent extraction process is a complex process. To design a reasonable technological process, we also consider the following factors:
Offer customized edible oil solvent extraction process solution according to different oil varieties (soybean, peanut, cottonseed, rapeseed, vegetable seeds…).
Ensure the edible oil solvent extraction process is adapted to the production capacity of your enterprise. Continuous edible oil solvent extraction process is suggested for production of large capacity, while batch type is more suitable for medium and small edible oil solvent extraction process .
Others, such as the reliability of the equipment and technology,labor productivity, theconsumptionrate of auxiliary materials, steam, water and electricity.
