Production Process of Flaxseed Oil
The production process of linseed oil mainly includes pressing method and special solvent extraction method. The pressing method involves applying pressure to the raw material to extract the oil from the oilseeds. The main advantage of this technology is that it does not require the use of chemical solvents and can produce a more natural product. All polyunsaturated fatty acids, proteins, food fiber, vitamins, trace elements and other useful substances are stored in flaxseed oil. 1. Oil Pressing method: Oil screening: The harvest of flax seed is cleaned, and the raw material is screened with a vibrating screen to remove the debris, so that the impurity rate is less than 0.5%. This step is to ensure the smooth progress of the subsequent pressing process and the quality of the oil. Roasting (hot pressing required) : If the hot pressing method is used, the flaxseed should be baked and fried, and the temperature and moisture of the pan should be strictly controlled. Roasting can improve th...
