Linseed Oil Production Technology

Make/Linseed Flaxseed Oil

Linseed/Flaxseed Oil Production is extensively practiced throughout the world. Linseed oil is a yellow coloured compound extracted by pressing dried flax plant seeds. It has an incredible history of over 5000 years being used as a food supplement and an effective medicine. This oil is also the world's seventh largest and China country’s largest oil crop. Rampant production of linseed has been found in many countries globally, including the United States, Canada, Argentina, China, and other south Asian countries. Approximately 2.4 million tons per year of linseed is produced all over the world.

ABC Machinery is now China TOP oil mill plant manufacturer and supplier after decades’ development and has transformed into a large modern enterprise combining research and development, design, production, sale, after-sale and trade.On this page, there are three kinds of linseed oil pressing technology, including hot pressing, cold pressing and oil extraction. What's more, ABC Machinery also provides the information of required equipment.

Three kinds of Linseed Oil Production Technologies

The production methods of linseed oil are generally hot pressing , cold pressing and solvent extraction.

1.Linseed Oil Hot Pressing production process

The new linseed oil hot pressing production process is a recently introduced technology that relies on conventional cooked pressing of flaxseed. It uses advanced manufacturing technology and an overall fabrication experience of that famous peanut oil with strong flavour, sesame oil and a number of other strong-flavour oils

Process details:
Flaxseed primary processing: flaxseeds used as raw material are high-quality and fresh, which are then pressed, added to flavoured oils under extremely high temperatures and dried. After drying, a mechanical pressing process takes place wherein these hot seeds are exposed to lower temperature.These dried and cooled up seeds are then taken through the process of stone and impurity removal, and separate the hollow, low-quality seeds. When all the iron and other impurities are removed from the seeds, they are placed into large hoppers and bifurcated into two pieces. The next step involves sending these separated and refined seeds into rotary drum roasting machines that provide an added aroma to these seeds at high temperatures.Selected linseeds are placed in flaking machines for further treatment and quality enhancement. 
Oil pressing processing: All the seeds are then sent into huge frying pan-like containers after which they are sent into the linseed oil pressing machine. The completion of the pressing process will produce strong flavoured crude oil which will be stored in huge tanks separately. Residues remaining after the pressing process are re sent to go through the production process all over again for greater results.
Oil extraction processing:Crude Oil extracted is sent into cooling pots through pumps. When the temperature drops down to about 30 to 35 degrees, it is poured out into filter plates where impurities and obsolete cake powder is refined out. The oil is then sent into heat exchangers and lastly drawn into large sedimentation tanks, where temperature generally drops to 15 degrees. After the production process is complete, extracted oil is stored in low temperature conditions ideal for them.

Linseed oil hot pressing process feature : 1. Increasing the oil yield   2.Improving the taste of the oil   3.Riching the fragrance

The hot pressing process of flaxseed oil is a simple, common and low-cost oil pressing process, which can obtain higher income with lower investment. If you are interested in the technology and equipment of oil extraction, please contact us!ABC Machinery has professionals to answer your questions!

2.Linseed Oil Cold Pressing production process

Linseed oil cold pressing refers to the vegetable oil extracted under great physical and mechanical pressure at low temperature, so it is called cold pressing. In this method, linseeds have not undergone the traditional high-temperature stir-frying or steaming process, so the oil is still distributed in the undeformed protein cells and contains abundant inherent components of flaxseed (linolenic acid and other nutrients).

Cold pressing process features: 
1. Avoid harmful substances caused by degradation of oils and sugars in high-temperature oil pressing and denaturation of proteins. 
2. Avoid the linseed oil color becoming darker and burnt smell caused by high temperature. 
3. After multiple filtrations, the direct contact and secondary pollution of chemical substances caused by sulfuric acid degumming, caustic deacidification and activated white earth decolorization process in the hot pressing process are avoided. 
4. Avoid high-temperature distillation and deodorization, effectively prevent the destruction of polyunsaturated fatty acid-α-linolenic acid in linseed oil at high temperature, effectively retain the natural complete nutrients, and make it easier for human body absorption and nutritional supplement.
Advantages: It retains almost all the nutrients in flaxseed, and its taste is refreshing and non-greasy, and it is rich in polyunsaturated fatty acids.
Disadvantages: lower oil yield and relatively high cost.

3.Linseed Oil Extraction and refining process

Linseed oil extraction method uses solvent oil (No. 6 light gasoline) to soak the oil raw material linseed and extract the oil at high temperature. The oil first extracted is a mixture of organic solvents and oils, which cannot be eaten directly and can only be eaten after a series of oil refining processes (dewaxing, degumming, dehydration, deodorization, deacidification, decolorization and other chemical treatments). After being extracted, the oil is generally lighter in color, which remains light original natural odor in the seeds or has no obvious odor. The extraction process can extract almost all the oil from linseed, and the economic benefit is very high. It is the most popular processing method in the modern oil industry.
