Flaxseed Oil Processing

Flaxseed oil, as a healthy edible oil rich in alpha-linolenic acid (Omega-3), is produced from flaxseed after processing. The production process includes flaxseed cleaning, crushing, steaming, pressing, refining, and packaging. Every 100g of flaxseed can be extracted from 30g of oil. 100g of flaxseed oil, saturated fatty acids accounted for 9%, oleic acid accounted for 17%, and the total unsaturated fatty acids was 74%. Which contains α-linolenic acid at 57%, and linoleic acid is 16%.

Linseed oil is widely used in the food, pharmaceutical, cosmetics, and other fields. Huatai Oil Machinery has rich experience in flaxseed oil processing solutions. We can provide 10tpd-2000tpd complete flaxseed oil plant turnkey project.

Flaxseed Pretreatment

After obtaining the flaxseed, it needs to be treated first. The purpose is to remove impurities (such as dust, straw, stones, metal fragments, etc.) and moisture on the surface of the flaxseed, and to maintain the integrity of the flaxseed. Common raw material processing steps include washing, sieving, and drying. The washing process can involve washing with water to remove the seed coat and other impurities. The purpose of sieving is to remove larger impurities and bad seeds. Drying serves to volatilize the water out of the flaxseed and improve the quality of the oil.
Crushing and Cooking

The pretreated flaxseed is then crushing and cooking. This is to increase the surface area of flaxseed and adjust the fewer points in it, to facilitate the subsequent extraction of oil. First of all, the use of a crusher for crushing generally requires the crushed flaxseed particles of uniform size. This is conducive to oil leaching, but will not destroy its internal structure. Then the crushed flaxseed into the cooker, under the control of good temperature, humidity, and time conditions for steaming and stir-frying.
Flaxseed Oil Pressing

Next, use the flaxseed oil press machine or screw oil press machine to press the steamed and fried flaxseed for about 1 hour. The oil is squeezed out of the cells and the extracted flaxseed oil is separated from the residue. The pressing process needs to control the pressure and temperature to ensure the quality of oil.
Decolorization and Filtration

Then, adsorbents such as activated carbon and white clay are used, which are mixed with flaxseed oil, and the adsorption capacity of the adsorbents is utilized to remove the pigments and impurities in the oil and grease. The adsorbent is then separated from the oil by filtration, eliminating any residual solids. The purpose of decolorization and filtration is to further purify the flaxseed oil and improve its color and quality.
Refining and Packaging

Finally, the decolorized and filtered flaxseed oil is then refined, refining includes deacidification, deodorization, and dewaxing. Refining is to remove free fatty acids, aldehydes, ketones, and other volatile substances and waxes in linseed oil to ensure the quality and taste of the oil. The refined flaxseed oil is then packed through an automatic filling machine to maintain its quality and hygiene.
