Cottonseed oil processing solution -- Cottonseed processing, solvent extraction and refining production line
Date:Nov 18th, 2022
Cottonseed oil is extracted from cottonseeds which are by-products of cotton fibre production. Cottonseeds are rich in oil and proteins and are therefore used for cottonseed oil production and as a feed supplement for cattle and sheep. Cottonseed oil is a type of vegetable oil used mainly as food. China is the world's largest cottonseed oil producer, followed by India, Pakistan, the USA and Uzbekistan.
Cottonseed oil can be used to make salad oil (mayonnaise, salad dressings, sauces and marinades), cooking oil for frying in both commercial and home cooking, and margarine or shortening for baked goods and cake icings. Besides, limited quantities may be used for producing industrial products such as soaps and cosmetics.
Dingsheng Machine provide complete cottonseed oil and cottonseed deep processing solutions include cottonseed pre-treatment, cottonseed cake solvent extraction, crude oil refining, cottonseed oil hydrogenation, refined cotton cellulose, cotton protein and more. Our complete range of products and advanced processes help you improve capacity and quality metrics while meeting increasingly stringent environmental and health requirements.
Cottonseed processing and pre-press process
The cottonseed pre-treatment process includes screening, cleaning, shelling, crushing, flaking, steam cooking and other process.
The pretreatment equipment adjusts the temperature, moisture and internal structure of the cottonseed to make the cottonseed reach a good state before pressing, which is convenient for extracting more oil during the pressing process.
Cottonseed oil adopts physical pressing method, and the pressing efficiency and the stability of the oil press machine are the keys to the oil extraction process. Our oil press machine have the advantages of large output, low cake residue and good quality cake. Some cottonseed oil and cottonseed cake can be obtained after pre-pressing.

Cottonseed cake solvent extraction process
The pre-treated cottonseed cake can be sent directly into the leaching plant for processing, The cottonseed cake leaching workshop consists of solvent leaching system, wet meal desolvation system, mixed oil evaporated stripping system and solvent recovery system. There is more residual oil by one-time pressing, we can use pre-pressing leaching method to obtain more cottonseed oil and bring high economic benefits.
Dingsheng Machine design negative pressure evaporation technology, innovative technologies are dedicated to saving energy and reusing materials, ensuring excellent quality of cottonseed oil, helping to improve energy efficiency and heat recovery, and reducing steam consumption.
Cottonseed contains a kind of glyhol that is harmful to the human body. Whether it is squeezing or leaching cottonseed oil, it must be must be refined. Dingsheng Machine provides three types of cottonseed oil refining equipment: batch refining equipment, semi-continuous refining equipment of cottonseed oil, and full continuous refining equipment.
Cottonseed oil refining process
Cottonseed oil refining equipment can remove various impurities such as collagen -soluble impurities, free fatty acids, pigments, and odors in puff seed oil, and improve the stability of cottonseed oil.
The cottonseed oil refinery workshop has the water degumming process, deacidification process, deodorization process, bleaching and filtration process and fractionation process, after these processes are refined, the oil can be removed from harmful substances and most impurities.
Cottonseed oil degumming is generally used in water dehydration process. Adding a certain amount of phosphoric acid solution to condense the colloid impurities, and then sink the colloid impurities and separate the oil.
Cottonseed oil deacidification process has two kinds: chemical and physical. The chemical deacidification process is to add alkali liquor to react with FFA to generate nigre and the physical deacidification process is using high temperature steam to distill the FFA out.
After deacidification, the crude cottonseed oil need to be decoloried by bleaching method. It is usually to use white clay to absorb the pigments, at same time absorbing residual gums and soapstocks. And then through filtering by plate filter, the waste clay will be filtered out. Cottonseed oil decolorization process is mainly to make the oil color more lighter, and qualified the national standard.
Cottonseed oil deodorization process often uses distillation principle, injecting high temperature steam to distill the odors out. The deodorization process can not only remove the odors from crude cottonseed oil, but also improve smoke point, flavor, steadily and quality of final oil.
At last, cottonseed oil refining has a special process -- cottonseed oil fractionation process. It is to seperate the solids and liquids in cottonseed at a specific temperature. Similar with palm oil fractionation process, through cooling, crystallization and filtration, you can get two parts: cottonseed oil olein and cottonseed oil stearine.
Cottonseed meal is a good source of protein. It is the byproduct remaining after cotton is ginned and the seeds crushed and the oil extracted. The remaining meal is usually used for animal feed and in organic fertilizers. Most of the meal is extracted mechanically through cottonseed kernels.
Dingsheng Machine is committed to optimizing technology processes, reuse processing by-products while increasing annual output, help cottonseed oil mill achieve higher processing capacity and improve their products quality and profit.
Dingsheng Machine provides complete plant solutions for converting cottonseed to cottonseed oil and cottonseed protein. Our comprehensive range of products helps you to increase yield while meeting increasingly stringent environmental and health requirements.
