Cottonseed oil can be extracted by pressing and extraction. For cottonseed oil mills with small output, the cottonseed oil pressing production line can meet the demand. However, for large-output cottonseed oil processing, such as oil mills with more than 30 tons, cottonseed oil pre-pressing extraction production line can be used, that is, the cottonseed is pre-pressed first, and then the pressed cake is crushed and sent to the cottonseed oil extraction equipment to extract the remaining oil. The advantages of the pre-pressing extraction process are that it can increase the oil yield, and has high output, good quality of cake after extraction, easy equipment operation, less labor, and reduced production costs. Therefore, for cottonseed oil mills with 30TPD processing capacity, the cottonseed oil pre-pressing extraction production line is a good choice.

The workflow of cottonseed oil pre-pressing extraction production line is as follows:

Cottonseed - cleaning - delinting - shelling - kernel and shell separation - flaking - steaming and frying - pre-pressing - extraction - refining

Whether it is the cottonseed oil press or extraction equipment, the cottonseed oil produced must be refined by cottonseed oil refining equipment before it can be eaten. The main reasons are as follows:

1. Cottonseed oil contains cottonpol, which is a toxic substance that can cause loss of appetite, neurological disorders, weight loss, and affect fertility. Eating cottonseed oil containing more cottonpol can cause poisoning. Cottonpol is weakly acidic. In the dephosphorization and deacidification process of the cottonseed oil refining equipment, it can react with alkali to generate water-soluble cottonpol sodium salt, which can be eliminated along with soap stock..

2. In addition to cottonpol, crude cottonseed oil also contains phospholipids, proteins, and colloidal impurities composed of trace elements, free fatty acids, waxes, and other impurities. Harmful impurities need to be removed through cottonseed oil refining equipment to ensure the edibility and quality of cottonseed oil and extend the storage time of oil. Therefore, untreated cottonseed oil is not edible.

The cottonseed oil refined and impurity-removed by the cottonseed oil refining equipment removes toxic substances such as cottonpol and can be eaten by humans. Cottonseed oil contains a large amount of essential fatty acids for the human body. The fatty acids contain palmitic acid 21.6-24.8%, stearic acid 1.9-2.4%, arachidic acid 0-0.1%, oleic acid 18.0-30.7%, and linoleic acid 44.9-55.0%. It is suitable for mixing with animal fat for consumption, because the content of linoleic acid in cottonseed oil is particularly high, which can inhibit the rise of cholesterol in the blood and maintain human health.
