New Technology Soybean Oil Manufacturing Machine
New technology soybean oil manufacturing machine
The whole soybean oil manufacturing machine contains three workshops: soybean pretreatment and prepressing workshop, soybean oil extraction workshop and soybean oil refining workshop.
1. Craft flow for soybean oil pretreatment and prepressing workshop
soybean→ magnetic box → cleaning → crusher → flaking roll → cooker → oil prepressing → to extraction workshop
Main Equipments:
1. Peanut: It’s a kind of main oil seeds. It’s used to make peanut oil around the world.
The oil content in peanut seed is about 48-55%.
2. Magnetic box: Clearing the iron impurity which might be in the peanut. Since in the process of puffing, the iron impurity will be harmful to the screw of extrusion machine, affect the puffing effect.
3. Cleaning: This parts have different size cleaning sieves to clean the different impurities. After going through this part, most of the impurities are moved from peanut.
4. Crusher: Because of the big size of peanut, it need to be crushed to small pieces. The crusher will help to get more peanut oil from the seeds.
5. Cooker: This machine can adjust the water content of the peanut. It’s also good for the prepressing and oil extraction section.
6. Prepressing: This machine is used to take parts of the oil in the peanut first, because the high oil content in the peanut. Then the crude oil will sent to peanut oil refinery workshop, and the cake will sent to peanut oil extraction workshop.
2.Craft flow for soybean oil extraction workshop
solvent
↓
extractor → mixed oil → 1st and 2nd evaporation → stripping tower → crude peanut oil
Wet meal → DTDC toaster → soybean cake
Main Equipments:
1. Solvent pumps: continuously spray solvent to the rotary-typr extractor.
2. Roary 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 phospholipid 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.

Loop type extractor
3. Craft flow for soybean oil refining workshop
Crude soybean oil → degumming and deacidification→ decolorization →deodorization → refined soybean oil.
Main Process:
1. Degumming and deacidification: The gumming is moved by phosphoric acid and hot water. There are two ways to move the acid in the peanut oil. One is chemical way, the other one is physical way. The chemical way is using NaOH to react with acid. This way is suitable for the capacity of 5-30T per day. The physical way is using steam and centrifugal to move the acid. This way is used for capacity from 30-2000T per day.
2. Decolorization: This step is used to adjust the color of the oil. You can control the color of the peanut oil according to the requirement of your market.
3. Deodorization: The function of this step is to move the special smell in the oil. This is an important standard for refined peanut oil. Because of the good smell of peanut oil, you can choose this step according to your market.
