Flaxseed Oil Production Line
Flaxseed oil contains an adequate amount of linolenic acid and the oil is usually extracted by low-temperature physical squeezing in the flaxseed oil production line. Because flaxseed oil has a balanced proportion of linolenic acid and linoleic acid, which is 1:4, and it is scientifically proven that when the ratio of linolenic acid to linoleic acid is 1:4, the human body can be in the healthiest state, and it is very difficult for various external bacteria to invade. Flaxseed oil can meet human health standards.
Currently, the sunflower oil sold on the market is mostly produced by de-shelled pre-squeezing and leaching process. De-shelled pressing-leaching technology is the key point of sunflower oil production line which avoids the negative impact of over-refining, high temperature, and acid and alkali effects on oils, so that the nutrients in the oil can be well preserved. For example, the content of vitamin E in de-shelled squeezed sunflower oil is 75.5mg/100g. However, by squeezing-leaching seeds with shell, every 100g sunflower oil only contains 41.62mg vitamin E. What’s more, there is no contact with alkane in the process of the un-shelled pressing-leaching process, which avoids the formation of trans fatty acids.
Processing Steps of Flaxseed Oil Physical Press Line
The pressing production process keeps the most effective ingredients in flaxseed, such as polyunsaturated fatty acids, protein, dietary fiber, vitamins, trace elements and so on. The pressed oil is more suitable for a special supplement for human health. Normal temperature pressing method refers to the flaxseed oil extraction at room temperature under great pressure from physical machinery without the traditional process of high-temperature frying or steaming, so the normal temperature pressed oil still distributes in the undeformed protein cells and contains rich ingredients (linolenic acid and other nutrients).
The steps of flaxseed oil press line are mainly: Flaxseed selecting → screening → cleaning up impurities → crushing → flaking → conditioning →normal temperature pressing → residue separation → degumming →dehydrating → debittering → crystallization → cryogenic filtration → physical pressed linseed oil1.Material selecting
2. Cleaning & sorting
7. Residue separation
8. Hydrated degumming
10. Crystallization & crystal growing
Due to the unique production technology of normal temperature pressed linseed oil, the requirements for raw materials are more stringent, therefore, fresh and plump flax seeds should be selected. The acid value of oil produced by immature and aged grains is higher and the flavor is poor, while mildew and broken grains are liable to be polluted by aflatoxin, so immature, damaged, mildewed and aged grains cannot be used to produce flaxseed oil. In addition, the following indicators should also be controlled: oil≥32%, moisture≤9%, impurities≤2%, acid value (KOH)≤1.0mg/g, peroxide value≤5mmol/kg.
At present, the commonly used raw materials for pressing flaxseed contains 38%~45% of oil and 6.5%~8.5% of moisture
Advantages of Our Flax Seed Oil Production Line
First, our oil pressing line has flexible production capacity, it can be equipped with complete industry standard equipment or can also be customized according to the actual needs of different customers. The equipment has large processing capacity and low failure rate, which ensures higher working efficiency. The normal continuous working hours of the equipment are fully guaranteed and the service life is long, which can create greater economic benefits and production capacity for the users.
Second, the material of our low-temperature oil pressing line must be carefully selected, and the whole temperature during the oil extraction procedure is relatively low. Therefore, the color of the extracted crude oil is lighter and the acid value is lower. Generally, our production line does not require chemical refining, but only needs to go through hydration degumming, activated charcoal debittering, cooling, filtration, dewaxing, etc. which avoids the effect of chemical refining process such as alkali refining, decolorization of activated clay and high temperature vacuum deodorization on the quality of flaxseed oil.
Application of Low-Temperature Pressed Oil
Our production line uses pure physical methods to extract flaxseed oil, so no chemical reagents or chemical residue reagents are added during the extraction process, and the oil is suitable for making excellent high-quality cooking oil and cosmetics, or pharmaceutical additives. The oil has a unique flavor, which can be widely used for cooking various foods and dishes. It has high nutritional value and health care and ensures high antioxidant activity. What’s more, our low-temperature oil press line is especially suitable for producing special oils and fats in small-batch oil workshop.
