The introduction of cotton seed oil processing

There are two main cotton seed oil processing methods: one is the pretreatment pressing method, and the other is the solvent extraction method. Different extraction methods use different cotton seed oil processing equipment. Pressing is a process of obtaining cotton seed oil from cotton seed by mechanical pressing. Solvent extraction is a process of obtaining cotton seed oil from processed cotton seed cake by using the principle of solvent and oil miscibility. Below is the introduction of cotton seed oil processing methods.

1. The pressing method of cotton seed oil processing

The cotton seed oil production line by pressing method includes the following steps: cotton seed pretreatment, cotton seed oil pre-pressing and cotton seed oil pressing. The purpose of cotton seed pretreatment is to clean impurities in cotton seed, adjust the moisture, temperature and internal structure of cotton seed, so that cotton seed can reach a good state before pressing, thereby improving the production efficiency of cotton seed oil. The cotton seed pretreatment equipment used includes cleaning equipment (magnetic separator, cleaning screen and stone remover), shelling equipment, kernel and shell separation screen, embryo rolling machine, steaming and frying pan and other equipment.

Next, the treated cotton seeds are pressed twice using a cotton seed oil pre-press and a cotton seed oil press, and the cotton seed oil obtained retains its natural aroma and its nutrients are not destroyed. At this point, the cotton seed oil processing by pressing is complete.

2. The solvent extraction method of cotton seed oil processing

Similar to the pressing method, the solvent extraction method also includes cotton seed pretreatment and cotton seed oil pre-pressing. The cotton seed pretreatment equipment adjusts the internal structure of cotton seed to a state suitable for extraction. After being processed by the cotton seed oil pre-pressing machine, raw cotton seed oil and cotton seed cake can be obtained. The cotton seed cake is transported to the extraction workshop for further production of cotton seed oil.

The cotton seed oil production line by solvent extraction is divided into four steps: the first is the extraction system, the second is the wet meal desolventization, the third is the mixed oil evaporation and stripping, and the fourth is the solvent recovery system. In the cotton seed oil extraction process, the cotton seed meal and the solvent are first contacted to make the oil and solvent in the meal blend to form a mixed oil. After the mixed oil is evaporated and stripped by the mixed oil treatment system, the solvent is vaporized and discharged to obtain crude cotton seed oil.

3. The refining method of cotton seed oil processing

Cotton seed oil contains a harmful substance to the human body - gossypol, whether it is extracted by pressing or solvent extraction method, cotton seed oil must be refined before consumption. Cotton seed oil refining equipment can remove colloidal impurities, free fatty acids, pigments, odors and other impurities in cotton seed oil, and improve the stability and market value of cotton seed oil. The cotton seed oil refining process includes degumming, deacidification, decolorization and deodorization. After refining, cotton seed oil that meets national standards can be obtained and sold on the market to obtain profit income.

Above is the introduction of cotton seed oil processing methods. The two cotton seed oil production processes have similarities and obvious differences, but there is no distinction between good and bad. It is just necessary to consider your cotton seed quality, processing volume, market requirements for finished oil, investment budget and other factors, and then select the appropriate cotton seed oil processing. The same production process can also choose to configure different cotton seed oil processing equipment according to the budget cost. In short, Henan Glory Company can customize suitable cotton seed oil processing equipment for you. We can realize every reasonable requirement of yours and satisfy you.
