Peanut oil production plant mainly contains three workshops:

Peanut seeds pretreatment and prepressing workshop

Peanut seeds solventl extraction workshop

Peanut oil refining workshop.

Main features of peanut oil production plant:

1. Saving Labor: it can save 60% labor for the equal output and 40% labor cost per day, for one or two people are able to make production.

2. Widely used: it can used to completely press more than 20 kinds of oil crops, such as peanuts, sesames, vegetable seeds, peanut, and so on

3. Pure oil quality: the vacuum oil filtering is used to remove residue so as to ensure the pure oil quality and meet the standard of health quarantine

4. Production input capacity: 1-200T/D

1. Description of peanut pretreatment workshop:

Craft flow for peanut pretreatment workshop:

peanut → magnetic box → cleaning → Crushing →Cooking →Pressing→ Crude oil & Cake to extraction workshop

Main Equipments:

1. Magnetic box: remove iron impurities in the peanut.

2. Cleaning: remove dust, straw and other dirts in the peanut.

3. Crushing machine: remove husk of peanut, in order to get more oil out.

4. Cooking: adjusting the moisture and temperature of the seeds, making it best state before pressing.

5. Pressing: specially designed oil press machine, oil residue is lower than 6-7%.

2. Description of peanut oil extraction machine workshop:

Craft flow for peanut oil extraction workshop:

solvent                                                                     

      ↓                                                                                  

extractor → mixed oil → 1st and 2nd evaporation  → stripping tower → crude peanut 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. Description of peanut oil refining workshop

Craft flow for peanut oil refining

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

Main Process:

1. Degumming and deacidification: The gum in the oil will moved in this step. There are different ways to process it.

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 move 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.
