500T/D Contton Seeds Oil Mill and Solvent Extraction Project in Xinjiang
We're here to help: Easy ways to get the answers you need.
Product Introduction
the factory successfully carried out the 500T/D Contton Seeds Oil Mill and Solvent Extraction Project in Xinjiang, Aug.2014.
Cotton Seeds Oil Production Line:
the pretreatment and prepress plant of Cotton Seed Oil Extraction Process include several section as below:
a.cleaning section
b.breaking section
c.flaking section
d, softening section
e.cooking section
f,oil press section
Main Equipments:
1. Magnetic box: Clearing the iron impurity in the cottonseeds. 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 cottonseeds 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 cottonseed pieces need be make to think cake. At the same time, the cell in the cottonseed 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.
Solvent extraction process of Cotton Seed Oil Extraction include:
extraction, desolventizer, Evaporative system, condenser.
Oil extraction, can be regarded as solid - liquid extraction. It’s use solvent has different solubility for different raw material to separate oil from the cakes.
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.
Oil Refinery process of Cotton Seed Oil Extraction is refining crude oil generally are Physical and chemical refining include Deodorization, degumming,deacidification, ,decoloring, dewaxing/winterising
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.
