Edible Oil Extraction Machinery

The whole process for edible oil extraction machinery includes oil seeds pretreatment, oil solvent extraction machine and oil refinery sections. 

1. Craft flow for oilseeds pretreatment workshop

Oilseeds  → magnetic box → cleaning → husking machine → flaking roll  →  plate dryer → to extraction workshop

Main Equipments: 

1. Magnetic box: Clearing the iron impurity in the oilseeds. In order to avoid the harmful to the following machines, the iron impurity need be moved first.

2. Cleaning: There are many different imputities in the oilseeds such as small stone, earth, straw and so on. They are not only broken the machine, but also effect the quality of final oil. 

3. Husking machine: This will help to separate the shell from the seed.

4. Flaking roll: The oil seeds pieces need be make to think cake. At the same time, the cell in the oilseeds is broken, so the oil is easy to go out.

5. Plate dryer: The water content of the extractor must be about 10%, so the dryer is used to adjust the water content in this step.

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

          Wet meal → DTDC toaster → cake

Main Equipments:

1. Roary extractor: The spray and soak the cake with solvent, so that oil fats can be dissolved in solvent 

(form miscella). After this step, wet meal and miscella (mixed oil) are got.

2. 1st evaporator: The miscella (mixed oil) will be sent to 1st evaporator to separate the oil and solvent.

About 85% of oil can be separated from the mixed oil in this step.

3. 2nd evaporator: After the separating in the 1st the evaporator, the mixed oil is sent to 2nd evaporator.

By the higher temperature and vacuum, 95% of the oil is get out from the solvent.

4. Stripping tower: This is the lastest step to separate the mixed oil. In this machine, all the oil will be seperated from the solvent.

5. DTDC toaster: The cake from the extractor will enter the DTDC toaster. The solvent in the cake can be moved out. Then the solvent can be recycled. The cake after separating solvent will dried in the toaster. Then you can storage it directly.

6. Condensers: The solvent from evaporate, stripping tower and toaster will recycled by the condenser. Then the running cost will be reduced. 

3. Craft flow for edible oil refining workshop

Crude edible oil → degumming and deacidification→ decolorization →deodorization → refined edible oil.

Main Process:

1. Degumming and deacidification: The gum and acid in the oil will moved in this step. There are different ways to process it. The physical way is suitable for low acid oil and big capacity, while the chemical way is suitable for the small capacity and high acid oil.

2. Decolorization: The white clay is used to move the color of the oil. For different market, people like different color oil, so you can control the color by the quantity of the white clay.

3. Deodorization: The oil will have the special smell of the oilseeds. It also contains the smell of white clay, so we need more the smell which people don't like. The high temperature steam is used to move the smell of the oil.

4. Winterization: There are much wax in the rice bran oil, so the winterization part is needed to move the wax in the rice bran. After moving the wax, the oil can keep clear in low temperature.
