Flaxseed Oil Extractor Machine
Flaxseed oil is made from flaxseed, which is a flax seed. It belongs to the family Flax, also known as flax. Because it is native to the East India region, when the Han Dynasty moved to the Western Region, it brought the linen back through the Silk Road. China, mainly planted in the old Xiongnu area, is the area where the "Hu people" gather, hence the name. Flaxseed is a traditional oil crop in China. Flax is divided into oil flax, oil fiber flax and fiber flax. Oil flaxseed is mainly produced in the Songnen Plain of Changbai Mountain and Heilongjiang Province, Inner Mongolia, and Liupan Mountainous Area in Ningxia. Zhangjiakou dam is on the north; Inner Mongolia has the most grassland distribution, and a small amount of planting in the northeast. Although flax has anti-barren habits, as oil flax, the three conditions of “cold climate, abundant soil, and sufficient light”are indispensable.
Flaxseed Oil Extractor Machine:
The oil produced by the leaching process is also called leaching oil, that is, the oil is leached with an organic solvent (such as gasoline, ethanol, etc.), and the leaching method uses solvent oil (No. 6 light gasoline) to soak the oil raw materials after high temperature extraction. An oil-making process that allows oil to be extracted. The "oil" originally immersed in is a mixture of organic solvents and oils and fats. It cannot be eaten and must be subjected to a series of refining processes (dewaxing, degumming, dehydration, deodorization, deacidification, decolorization, etc.) before it can be eaten. The oil is generally light in color and the initial natural gas in the material seed is light or has no visible odor. The leaching process can extract all the oil in the oil, and the economic benefit is very high. It is the most popular processing method in the modern oil industry.
Cold pressing process features: 1. Avoid harmful substances caused by degradation of oils and sugars in high-temperature presses and denaturation of proteins. 2, avoiding the high temperature and the linseed oil color becomes darker and there is a paste phenomenon. 3. After multiple filtration, 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, to avoid high-temperature distillation deodorization, effectively prevent high temperature damage to the polyunsaturated fatty acid - α-linolenic acid in linseed oil, effectively retain the natural complete nutrients, more easily absorbed by the body and nutritional supplements. 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.
Hot pressing process characteristics 1, can improve the oil yield, improve the taste of the oil, the fragrance is more intense. 2, easy to cause high temperature oxidative polymerization, decomposition of peroxides and some harmful substances, destroying the nutrients in the oil. 3, high temperature causes protein denaturation, greatly reducing the content of polyunsaturated fatty acids in linseed oil, and even produce trans fatty acids. 4, more impurities, such as flax seed dandruff, phospholipids, free fatty acids, etc., affecting the appearance of oil and the inherent quality of oil. Advantages: Flaxseed oil has a rich and mellow taste and a high oil yield. Disadvantages: High temperature frying seeds will reduce the content of active ingredients in the oil, leading to protein denaturation.
Flaxseed oil contains VE, which is a strong and effective free radical scavenger, which has the effect of delaying aging and anti-oxidation. Flax seeds contain 23 mg/100 g of flavonoids. Flavonoids have a good effect on lowering blood lipids and resisting atherosclerosis [7]. Flaxseed oil has a high content of unsaturated fatty acids and a high iodine value. It must be added with an antioxidant or a nitrogen-filled seal. The unsaponifiables of linseed oil is 8.26%, indicating that there are also a considerable amount of higher fatty alcohols, sterols and hydroxyls in linseed oil. Flaxseed is rich in minerals. The highest potassium content is much higher than the high potassium food oranges, peanut kernels and shrimps. Potassium is related to maintaining normal blood pressure in the human body. Zinc content in flaxseed is also high. Zinc is an essential trace element in the human body and plays an important role in maintaining normal physiological functions of the human body. The above indicates that flaxseed and seed oil have high nutritional value and can be used as raw material components for processed food, medicine or animal feed, and the comprehensive utilization and development prospects are broad.
