Chinese top brand of edible oil refining equipment | Oil equipment production line

    The whole soybean oil processing line equipment contains three workshops:  pretreatment workshop,  oil extraction workshop and oil refining workshop.

1. Craft flow for oil pretreatment workshop

Raw material → magnetic box → cleaning → crusher → soften → flaking roll → cooker → oil press(chosen) → to extraction workshop

Main Equipments:

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.

6. Press: The press machine is used to take parts of the oil in the soybean, when the capacity is low. It is not needed in the soybean oil extraction way. If you using solvent extraction way to get soybean oil, the flake can be sent to oil extractor directly from cooker.

2. Craft flow for oil extraction workshop

   solvent                                                                    

      ↓                                                                                 

extractor → mixed oil → 1st and 2nd evaporation → stripping tower → crude oil

     Wet meal → DTDC toaster →  meal

Main Equipments:

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

2. Roary 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. 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.

3. Craft flow for oil refining workshop

Crude 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 soybean 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 soybean 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 soybean oil.

1. What our machines can do?

We have pressing machine, solvent extraction machine, and refinery machine, our press/expeller can get cold pressed oil or hot pressed oil from peanut, sunflower seeds, corn germ, cotton seeds, soy bean, rapeseeds and other oil crops; our solvent extraction line can extracte oil from various cakes by solvent(leaching),like soy cake, peanut cake, sunflower cake and others; Our refining machine can help you get refined oil(decoloring oil, degumming oil, deacid oil), 1st to 4th grade cooking oil as your requirements.

The biodiesel machine can produce International standard biodiesel, like  EN14214 standard,  ASTM 6751-03 standard,  DIN V 51606 standard.

2. What's your factory's ability, which kind of machine do you manufacture? 

We can produce all kinds of edible oil machinery, which includes palm oil production machine, peanut oil, soybean oil, cotton oil, sunflower oil, corn oil, rice bran oil and other kinds of edible oil.

The whole line includes oil press line, oil extraction (solvent) line, oil refinery line, palm oil fractionation line, sunflower oil dewaxing line, decoloring process, deodorization process and others.

We can produce biodiesel plant/equipment/machines also. On the other hand, our factory developed ourselves, import many advanced technology to strengthen ourselves and ensure our customer's right.

5. Raw material

6. Biodiesel production line

New tech for recycling used frying oil, waste cooking oil and oil seeds to get biodiesel, the esterification method is a hot and renewable technology of the world. 

Biodiesel can be substitute of petroleum oil. The biodiesel is already widely applied as engine fuel in tractor, cars, sedans.

The advantages of bio diesel oil:

1. Green energy sources, environment friendly;

2. Sustainable energy sources, raw material is rich and steady;

3. Widely application and achieve the international standards.

4. It not belongs to dangerous cargo, easy to transport.

5. The supply of bio diesel is not controlled by OPEC, it’s benefit to the stability of   international petroleum market.
