Flaxseed oil machine
    Flaxseed oil machine production technology (1) cold pressing method of cold pressing oil production process. Flaxseed harvesting, screening → flaxseed → cleaning impurities → hulling → crushing → low-temperature pressing → pressing flaxseed oil → coarse filtration → fine filtration → low-temperature crystallization and crystal growth → low-temperature filtration → cold-pressed flaxseed oil
    Flaxseed oil machine cold pressing process features: 1, to avoid the degradation of fats and sugars in high-temperature pressing and harmful substances caused by protein denaturation. 2. Avoid the darkening of flaxseed oil caused by high temperature and the phenomenon of pasty taste. 3. After multiple filtration, direct contact with a kind of active ingredient and secondary pollution caused by sulfuric acid degumming, caustic soda deacidification, and activated clay decolorization in the hot pressing process are avoided. 4. Avoid high temperature distillation and deodorization, effectively prevent the high temperature from destroying the polyunsaturated fatty acids in the linseed oil, α-linolenic acid, and effectively retain the natural and complete nutrients, which is easier for the human body to absorb and supplement. Advantages: It retains almost all the nutrients in flaxseed, has a refreshing and non-greasy taste, and is rich in polyunsaturated fatty acids. Disadvantages: low oil output rate and relatively high cost.
    Flaxseed oil machine production process (2) Production process of hot-pressed hot-pressed oil Extraction and screening of flaxseed → flaxseed → cleaning up impurities → hulling → crushing → frying → pressing flaxseed oil → coarse filtration → After filtering → degumming → washing → dehydration → decoloration → deodorization → hot pressing linseed oil hot pressing method process characteristics 1, it can improve the oil yield, improve the taste of the oil, and the flavor is relatively strong. 2. It is easy to cause high-temperature oxidative polymerization and decomposition to produce peroxides and certain harmful substances, which destroys some kinds of nutrients. 3. High temperature causes protein denaturation, which greatly reduces the content of polyunsaturated fatty acids in linseed oil, and even produces trans fatty acids. 4, more impurities, such as flax seed dander, phospholipids, free fatty acids, etc., affect the appearance and color of the oil and the inherent quality of the oil.
    Flaxseed oil machine production process advantages: Flaxseed oil has a rich, mellow taste and a high oil yield. Disadvantages: Frying seeds at high temperature will reduce the content of active ingredients in the fat, resulting in protein denaturation.
    Flaxseed oil machine production process (3) Leaching method advantages: very high oil yield, low cost and higher economic benefits. The most popular processing method in modern grease industry. Disadvantages: Almost all nutrients are destroyed, and traces of organic solvents remain.
    Flaxseed oil machine production process (4) Temperature analysis The key influence of temperature on edible oils: fragrance and taste, it is the ancient times, nowadays, the nutrition value is more important today. When the temperature of the cooking oil exceeds 80 °, the nutritional content of the cooking oil starts to be destroyed. After the cooking oil is put in the oil, the fragrance will be pleasant and the nutrition will start to be emitted.           Generally, the oil temperature for cooking is suitable for 70-80 degrees, and the maximum temperature for fried foods is 150 degrees. If the oil temperature is higher, other substances will be generated or decomposed. If the oil temperature is above 250 ° C, the substances in the oil will undergo oxidation, hydrolysis, polymerization, cracking and other reactions, and will evaporate with the boiling oil. Flaxseed oil has a boiling point of 287 ° C. If the oil temperature is too high or high (more than 287 degrees) for a long time, it will turn black. Oxidative decomposition and even carcinogenesis; cooking oil also contains a variety of mutagenic substances. Vegetable oil and soybean oil contain more unsaturated fatty acids and have mutagenicity; suggestion one: The temperature of linseed oil cooking is best controlled below 80 °. Suggestion 2: The contamination produced by cooking oil heat below 180 ℃ will be less. Think carefully about frying
