Cottonseed oil introduction:
Cottonseed oil is a cooking oil extracted from the seeds of cotton plants of various species, mainly Gossypium hirsutum and Gossypium herbaceum, that are grown for cotton fiber, animal feed, and oil.Cotton seed has a similar structure to other oilseeds such as sunflower seed, having an oil-bearing kernel surrounded by a hard outer hull; in processing, the oil is extracted from the kernel. Cottonseed oil is used for salad oil, mayonnaise, salad dressing, and similar products because of its flavor stability.
These are 20% protein, 20% oil and 3.5% starch in cottonseed. Cottonseed is a common raw material oil seeds in some countries. Cottonseed oil is used for salad oil, mayonnaise, salad dressing, and similar products because of its flavor stability.
How to get cottonseed oil from cottonseeds?
Cottonseed oil making process usually uses Cottonseed Oil Press Machine, Cottonseed Oil Extraction Machine and Cottonseed Oil Refining Machine. The follow picture is a detail introduction about cottonseed oil pretreatment and pressing process flow:
Cottonseed oil pretreatment and pressing process
Cottonseed pretreatment equipment and cottonseed oil press machine designed by our factory absorbs superior designs which can achieve the best quality cottonseed for pretreatment. Cottonseed pretreatment workshop is mainly to remove impurities in cottonseeds, regulate moisture and temperature of cottonseed, and break cottonseed into small particles to change cottonseed molecular structure,etc, which is good for the following process in solvent extracton workshop. After pretreatment, we can get cottonseed cake. Cottonseed cake can go to the following solvent extraction workshop.
Cottonseed oil extraction process:
The cottonseed oil extraction equipment designed by our company adopts advanced process design, with easy installation of equipment, safe characteristic and automation, small energy
consumption, good effect of extraction, low residual oil in meal, and good quality of meal and oil.
Cottonseed oil extraction production line get crude extraction oil from cottonseed cake through processing flows of solvent extracting, mixture oil filtration, wet bran treatment of dephenolizaiton and mechanical desolvent, and low temperature drying, evaporation, gas stripper to obtain crude cottonseed oil.
Cottonseed oil extraction process
Major processes of cottonseed oil extraction:
1. Oil extraction process
2. Steam removal process
3. Evaporation process
4. Solvent cooling and water separation process
5. Tail gas absorption process

Why Refining Edible Oil?
The crude oil obtained from oil expellers or solvent extraction contains impurities such as phosphatides,free fatty acids (FFA), pigments, off-flavor, etc. Oil Refining is a series of process to remove these impurities. After refining, the flavor, color and smell of oil is improved, the stability is improved which is good for long time storage, the smoke point of oil is increased.
Cottonseed oil refining machine adopts continuous oil refining process line including unique degumming, deacidification, decolorization, negative blenching, high vacuum steam ejection deodorization,dewaxing, filtering and fully automatic control system, ensuring the most advanced cottonseed oil refining quality as well as environmental protection, energy saving, low consumption etc.
We can provide design, manufacture, installation, calibration and after service of cottonseed pre-pressing & extraction &refining production line. Welcome consulting if you are interested in our machines.
