A complete set of machinery and equipment for extracting oil from sunflower seeds
Sunflower seeds, also called sunflower seeds, are the fruits of sunflowers. Its seeds contain 30%-45% fat, and the most can reach 60%. Sunflower seed oil is golden in color, clear and transparent, and has a delicate smell. It is an important edible oil. It contains a large amount of linoleic acid and other essential unsaturated fatty acids, which can promote the regeneration and growth of human cells, protect skin health, and reduce the accumulation of cholesterol in the blood. It is a high-grade nutrient oil. It is golden in color, clear and transparent, and has an aromatic smell.
The consumption of sunflower oil worldwide ranks fourth after palm oil, soybean oil and rapeseed oil among all vegetable oils. It is one of the important edible oil varieties in European countries. Many countries and regions in the world, such as Taiwan, Hong Kong, Japan, and South Korea, consume as much as 70%, and they are also the main edible oil for Europeans and Russians.
Sunflower oil is a healthy edible oil known for its high content of linoleic acid. In the 21st century, cardiovascular and cerebrovascular diseases such as coronary heart disease, cerebral apoplexy, cerebral thrombosis, arteriosclerosis, high blood pressure and other diseases have increased, and long-term consumption of suitable oil products can greatly improve the above symptoms. Sunflower seed oil is one of the most excellent healthy fats, and it has become the oil of choice for consumers and chefs. Because it is rich in linoleic acid and rich in nutrients for maintaining human health, it is known as "good health care", "high-grade nutrient oil" or "healthy oil" abroad.
Sunflower oil extraction machine manufactured by Dayang Company processes the extracted oil. After refining, it is bright and beautiful light yellow or blue-yellow, with a fragrant smell and pure taste, and contains sterols, vitamins, linoleic acid and other substances beneficial to humans. The content of natural vitamin E is the highest among all major vegetable oils; and The content of linoleic acid can reach about 70%. It can lower serum cholesterol levels, lower triglyceride levels, and lower blood pressure. Moreover, it is light and transparent, can retain the natural food flavor during cooking, and its smoke point is also high, which can avoid the harm of oil fume to the human body.
The composition of fatty acids in sunflower oil is affected by climatic conditions. The fat produced in cold regions contains about 15% oleic acid and about 70% linoleic acid; the fat produced in warm regions contains about 65% oleic acid and about 20% linoleic acid. The human digestibility of sunflower oil is 96.5%. In addition, the content of α-tocopherol with the strongest physiological activity in sunflower oil is higher than that of general vegetable oil. Moreover, the ratio of linoleic acid content to vitamin E content is relatively balanced, which is convenient for human body to absorb and utilize. Therefore, it is an excellent edible oil with high nutritional value and beneficial to human health.
Sunflower seed oil also contains more vitamin E, about 100-120 mg per 100 grams. It has a good function of delaying the aging of human cells and maintaining youth. Regular consumption can strengthen the body and prolong life.
The oil extracted by the sunflower oil extraction machine also contains more vitamin B3, which is effective in treating neurasthenia and depression. It contains a certain amount of protein and inorganic substances such as potassium, phosphorus, iron and magnesium, which are effective in the treatment of diabetes and iron deficiency anemia, and are of great significance to the healthy growth of bones and teeth in young people. The linoleic acid it contains is an essential fatty acid for the human body, which contributes to human development and physiological regulation, and also has a positive effect on preventing dry skin and scaly hypertrophy.
Sunflower oil contains trace amounts of plant alcohols and phospholipids, these two substances can prevent the increase in serum cholesterol. It is rich in carotene, more than peanut oil, sesame oil and soybean oil. It also contains nutrients such as glucose and sucrose, and its caloric value is also higher than that of soybean oil, peanut oil, sesame oil, corn oil, etc., which can produce 9.499 calories per gram. Its melting point is also low, suitable for being absorbed by the human body, and the absorption rate can reach more than 98%. In addition, it is slightly heated and has a strong fragrance. It is the best edible oil except sesame oil.
Because it is rich in nutrients and has a variety of health-care functions for the human body, it is known as the "high-grade nutritional oil". It has been selling well in the international market in recent years and has been very popular.
Process introduction of sunflower oil extraction production line
After the sunflower seeds are cleaned, peeled, embryo rolled, steamed, fried, and oil squeezed in the pretreatment workshop, the pre-pressed sunflower seed cake is sent to the extraction workshop for oil extraction. The pre-pressed and extracted crude oil undergoes degumming, deacidification, decolorization, deodorization, and dewaxing processes to obtain refined sunflower oil.
Pretreatment and pre-squeezing process: Sunflower seeds are dehulled and pre-squeezed. The raw materials are first cleaned, dried, and then homogenized in the steel silo for a few days before processing. During processing, they are re-cleaned, dehulled and dried in the workshop. The dried and homogeneous sunflower seeds have a moisture content of 7, and the hardness and strength of the shell are uniform.
During processing, the sunflower seed material is screened, wind-separated and magnetically separated, and then enters the sheller to peel the shell, and then separates the shell and kernel in the shell and kernel separation screen. It can also be directly pre-extruded and leached without shelling. The produced meal fiber The content is higher and can be used as cattle feed. After the shell and kernel are separated, the moisture and temperature of the kernel are adjusted by a softening pot, and then the kernel is rolled with a embryo rolling machine, and then steamed in a steaming pan, pre-pressed with a screw pre-press, and the extracted crude oil is filtered Crushed oil is sent to refining. The pressed cake is sent to the extraction workshop for oil extraction.
Pre-pressed cake extraction process of sunflower oil extraction production line:
Pre-squeezed sunflower cake → extraction → filtration → evaporation → steam stripping → leaching crude oil. After the oil is extracted, the meal is dried and stored.
The sunflower pressed cake in the pre-pressing workshop is transported to the leaching workshop, and enters the extractor through a buried scraper conveyor and sealed auger. With the operation of the extractor, the mixed oil of decreasing concentration is sprayed, and finally fresh solvent is sprayed to make The oil content in the feed is reduced to less than 1. The wet meal that has been extracted from sunflower oil is sent to the steaming machine by 2 buried scraper conveyors and sealed augers. Direct steam is sprayed into the steaming machine to remove the solvent. After drying Transport to the meal warehouse for packing. The mixed oil obtained by solvent extraction and dissolution of fats and oils is subjected to filtration, precipitation of mechanical impurities, evaporation, and steam stripping to remove the solvent to obtain leached crude oil.
The mixed oil adopts negative pressure evaporation technology, and uses the secondary steam of the steam-off machine as the heat source. The first steam, the second steam, and the stripper all work under vacuum, which reduces the evaporation temperature, improves the crude oil quality, and saves steam consumption. .
The solvent vapors separated by steaming, first steaming, second steaming, steam stripping, leaching, etc., are respectively recovered through the corresponding condensers, and the condensate is concentrated in the liquid collecting tank, and after entering the integrated container for water separation, the solvent is then pumped for leaching The device enters the next cycle, and the separated water is boiled in the cooking tank and the wastewater is discharged. The free gas of each condenser enters the balance tank, then enters the final condenser, and the tail gas is vented after the solvent is recovered. If sunflower meal is further processed, it is necessary to choose a more advanced low-temperature meal production process. The low-temperature meal protein has little denaturation. After chlorogenic acid is extracted, the sunflower protein isolate is processed.
Sunflower protein isolate is also written as sunflower seed protein, also known as sunflower protein. Sunflower seed kernels contain 21%-30% protein. It is a protein product that uses dehulled sunflower seeds to extract defatted sunflower seed meal without pressing one-time extraction and remove chlorogenic acid, caffeic acid and other phenolic acid compounds. The main component is globulin (about 70% to 79%), followed by albumin and a small amount of gluten and gliadin. In the amino acid composition, the content of lysine is lower, while the content of other essential amino acids is higher
Uses of sunflower protein isolate 1. Used in general food. After 1% to 2% of defatted sunflower seed protein powder is steamed for 1 hour in damp heat and added to bread and other foods, it can strengthen nutrition, make up for the insufficient content of essential amino acids in flour, and increase the elasticity of bread crumbs to prevent flour The effect of starch aging.
2. A good additive for baby food. Compared with soybean protein, sunflower seed protein has lower lysine content, but higher methionine content. Combine sunflower seed protein with soy protein and add it to infant foods to enhance nutrition
3. Additives in meat products. When sunflower seed protein is added to sausages and other meat products, the shrinkage is small during smoking, which can not only prevent oil separation and reduce weight loss, but also increase the tenderness of sausages and make the products more palatable. Adding sunflower seed tissue protein (30%) to fillings of pies, buns, dumplings and other foods instead of pork can not only reduce animal fat in foods, reduce cholesterol content, but also reduce costs.
4. Make artificial milk and other beverages. Sunflower seed protein has a soft smell and no peculiar smell such as bey, it is a good raw material for high-end beverages and artificial milk. The sunflower seed protein concentrate is heat-treated at 80°C, mechanically stirred and then added with emulsifiers to make a 3% protein-containing emulsion. Mix it with milk in a ratio of 1:1 to obtain a better flavor and color. Of mixed milk.

Process Description:
After the crude oil is preheated, light alkali is added to make the gum and some free fatty acids in the oil form soapstock, and then the soapstock is separated, and then hot brine is added to the oil to wash, and the soap water is separated. Degumming is completed by the same washing time. The degummed oil enters the decolorization process, adds activated clay to decolorize in the decolorization tower, and then is pumped into the leaf filter for filtration. After polishing, the filtrate enters the next process. After the leaf filter is blown dry, the waste clay is discharged through vibration. The decolorized oil is pumped into the gas separator for vacuum deoxygenation, and then pumped into the oil-oil heat exchanger for heat exchange preheating with the deodorized oil, and then enters the heater when it is heated to about 250°C and enters the combined deacidification and deodorization tower in high vacuum state Deacidification and deodorization are carried out under the following conditions, and the volatile substances such as fatty acids and odors in the oil are removed to a large extent. The fatty acid mixed steam is discharged from the top of the tower into the fatty acid trapping system and sold. The oil is drawn from the bottom and pumped into the heat exchanger to exchange heat with the oil to be deodorized, and then cooled to obtain the deodorized oil. The deodorized oil is cooled and crystallized in a crystallization tank and then transferred to the crystallization stage. The crystallization and crystallization stage of the oil is pumped into a filter to separate wax and grease to obtain refined oil.
