Advanced cotton seed cake oil machine

WHAT OILSEEDS ARE AVAILABLE?

MAIN WORKSHOPS OF OIL PLANTS:

The complete oil plant usually includes three workshops: pretreatment/pressing workshop, solvent extraction workshop and oil refining workshop.

PROCESS FOR PRETREATMENT WORKSHOP:

oilseed→ magnetic separator→ cleaning → crusher → soften → flaking → cooker → pressing

(optional) → solvent extraction workshop

MAIN EQUIPMENTS IN PRETREATMENT WORKSHOP:

1. Magnetic box: Clearing the iron impurity which might be in the soybean. The iron impurity 

will be harmful to the following machines, so we need take the iron impurities out. 

2. 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 soybean.

3. Crusher: Because of the big size of soybean, it need to be crushed to small pieces.The 

crusher will help to get more soybean oil from the seeds.

4. Soften: This is a special step for soybean oil making. This step improves the ductility of soybean. Then the flake will be thin and not  fragmentary. This is helpful to the oil press part and oil extraction part.

5. Cooker: This machine can adjust the water content of the soybean. It’s also good for the press and oil extraction section.

PROCESS FOR SOLVENT EXTRACTION WORKSHOP:

MAIN EQUIPMENT IN SOLVENT EXTRACTION SECTION:

1. Solvent pumps: continuously spray solvent to the rotary-typr extractor.

2. Rotocel extractor: spray and soak the soybean 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.  1st Miscella tank: 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.  2nd Miscella tank: 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.
