Cotton seed is usually the by-product of ginnery factory, with 15-25% oil content rate. Most clients in Middle Asia like in Uzbekistan, Kazakhstan usually send inquiries to us to learn about the price of cotton seed oil press production line and the necessary equipment in cotton seed oil press production line. To help our clients understand that what machines will be used in the cotton seed oil press production line, Henan Doing Company’s engineer specifically summarized the following contents to guide you on cotton oil production.
If your cotton seed is with fluff (usually it is 12%), then first we need to use cotton seed stripping equipment to remove the fluff and make its content lower than 3%, because it will absorb the oil away.
The second step is cleaning, we usually use air separator to remove impurities like dirt, stones etc, besised, we need to use cyclone dust collector to remove the light impurities in cotton seeds.
Next step is flaking. For input capacity above 50TPD, you may need to add one flaking machine to make large cotton seeds into small flakiness, so that it will be easier to get oil out.
After flaking process, we need to use cooker to adjust the moisture and temperature of the flakiness, making it into the best state before pressing.
Finally, we need to use cotton seed oil press machine or cotton seed oil pre-press machine to extract cotton seed oil out. In cotton seed oil pressing station, customers usually are often faced with two choices, one is using presser to press oil directly, this method can ensure the residual oil in the cake is less than 8%. Another is using cotton seed oil pre-presser to get part oil first, then send pressed cotton seed cake to solvent extraction plant to extract more cotton seed oil out. Usually, the cotton seed cake solvent extraction plant can ensure the residual oil in the cake is less than 1%.
