How to squeeze oil from oil sand beans, can you squeeze oil in ordinary ways?

Oil sand beans can be pressed for oil, and they can be pressed with a spiral oil press.

Oil can be squeezed with sun-dried oil sand beans, and its oil yield is about 15%-20%.

It is an annual herbaceous plant of the sedge family, which is native to the Mediterranean coast of Africa and is a vegetable oil resource with high comprehensive utilization value. Since it was introduced into China in 1960, the planting scale and processing volume have increased year by year in recent years, with an annual output of about 30,000 tons. The existing extraction methods include extraction method, solvent leaching method and supercritical extraction method.

The organic solvent extraction method for the extraction of soybean oil has strict production equipment and operation requirements, and there are potential safety hazards and environmental pollution in the extraction process. The supercritical extraction method does not destroy the original components in the oil, but the production cost is too high.

Process 1; Crushing and extraction process:

Clean oil beans, crushed, steamed, fried, pressed, crude oil, refined, refined oil, packaged.

The physical pressing method can keep the various nutrients in the soybean oil from being destroyed, and the disadvantage is that the oil yield is low, but the oil produced by this method is close to the original state, which is a processing method that is in line with human health.

Grease Filtration Equipment - Plate and Frame Filter.

Process 2; Leaching Extraction Process:

Clean oil beans, crushed, softened, rolled embryos, leached, crude oil, refined, refined oil, packaged.

No. 4 solvent leaching is used for the leaching process, and the oil yield is higher than that of the physical pressing method.

The method of soybean oil extraction is: soybean oil extraction needs to use the soybean oil press to extract oil, and it is difficult to manually extract soybean oil. Therefore, it is recommended to use a soybean oil press for oil extraction.

Soybeans are not only soybeans, but also black beans and green beans. Soybeans are nutritious and abundant, and the protein content is 2 times higher than that of pork and twice the content of eggs. The protein content is not only high, but also ***.

The amino acid composition of soybean protein is similar to that of animal protein, and the amino acids are relatively close to the ratio required by the human body, so it is easy to be digested and absorbed. If soybeans are eaten with meat and eggs, their nutrition can be compared with the nutrition of eggs and milk, and even exceed the nutrition of eggs and milk.

(1) Boiled beans: select high-quality mountain soybeans, add an appropriate amount of water to boil, and then remove them;

2) Steamed beans: Put the boiled mountain soybeans into the steamer and simmer for about 0 5 1 hours;

3) Hair enzyme: spread the steamed mountain soybean on the bamboo basket, and put the bamboo basket into the hot and humid environment for hair enzyme, the time is 1 2 days;

4) Enzyme washing: wash the enzyme bacteria with clean water after the enzyme soybean is released;

5) Soaking: Add 1 5 times of hot water to the washed mountain soybeans each time, and soak them many times;

6) Boil oil: Mix the multiple soaking liquid of mountain soybeans and pour them into a concentrating pot, first boil them over high heat, and then slowly boil them over low heat until the soaking liquid becomes thick. This makes soybean oil.

1. Soybean oil.

Generally, the crude oil with more impurities is obtained after treatment by various methods such as pressing method and leaching method, and then the edible refined oil is obtained after refining.

2. The squeezing method is divided into two types: ordinary squeezing method and spiral squeezing method. The ordinary pressing method is a method of pressurizing soybeans. This method is no longer widely used, especially in industrial mass production.

The screw pressing method is to install a screw shaft in the cylinder of the horizontal device, and the pretreated soybeans enter the screw press; Squeeze out the grease as you move forward. This method can be produced continuously, but during the oil extraction process, it is heated by friction.

Proteins are often changed to a greater extent.

3. The leaching method of oil production is to use the solvent that can dissolve the oil and fat, and leach the oil in the blank through the action of wetting and penetration, molecular diffusion and convective diffusion. Then, the mixed oil composed of solvent and fat is separated, and the solvent is ** to obtain crude oil. The most commonly used leaching solvents in the actual production of China's oil industry are several aliphatic hydrocarbons such as hexane or light gasoline.

Among them, light gasoline is the most widely used solvent, but the biggest disadvantage is that it is flammable and explosive, the composition is complex, and the boiling point range is wide. The oil yield of the leaching method is as high as 99%.

The production process of edible oil needs to go through both pressing and refining.

1) Pressing process.

Edible oil pressing methods are divided into mechanical pressing (divided into high-temperature physical pressing and low-temperature physical pressing) and solvent pressing (also known as leaching method).

In the high-temperature physical pressing method, the oilseeds are crushed with a spiral press, and then the oil is pressed out at 120 high temperature and high pressure.

The solvent generally used in the leaching method is ethane (No. 6 light gasoline), which can squeeze out 98% of the oil in the oilseeds. After that, the solvent is evaporated at a high temperature of 150 °C. A part of ethane will remain in the oil, ethane is harmful to the human body, and it is also very damaging to the environment.

Because of production efficiency problems, large edible oil manufacturing plants generally use solvents and high temperature and high pressure to extract oilseed oil. But high temperatures also have a great impact on the quality of the oil.

Of course, in order to maintain the quality of edible oil, some manufacturers will press the oil out by low-temperature physical pressing. In this way, the oil seeds are crushed by a press and the oil is squeezed out at high pressure. The efficiency of this method is much lower than that of the high-temperature and solvent method, and the oil yield is only about 60%, but the quality of the edible oil can be fully guaranteed.

2) Refining process.

In the process of pressing, after high temperature and high pressure, solvent and other procedures, the oil will become foul-smelling and gray in color, so large edible oil manufacturers usually refine the edible oil to remove impurities. The refining process includes bleaching, deodorization, degumming, adding pigments, fragrances, etc.

Edible oil that is physically pressed at low temperature usually does not require these steps, and is mainly filtered, which retains the flavor of the oilseeds, including natural flavor, natural pigments, trace elements, and so on.

It can be seen that the oil pressing method has a great impact on the quality of the finished edible oil, which cannot be ignored.

Hello, the oil is fragrant and self-pressed, but there is also a question of quality. Generally, the oil sold in the market is refined soybean oil, which is made by neutralization, decolorization, and deodorization processes. In contrast, unrefined soybean oil may have aflatoxins and other causes of diarrhea due to the beans.

Generally speaking, the oil yield of soybeans is only about 20%, that is, 5kg of beans, and generally speaking, you can get up to 1kg of soybean oil. Industrially, soybeans are leached to achieve the maximum oil yield, and if the oil is pressed, the oil yield will be lower.

If you are worried about the soybean oil on the market, you can choose a big brand manufacturer.

The oil bean (also called sand bean) is an oil crop that can be extracted from edible oil. Its oil extraction rate is related to a variety of factors, such as the variety of oil swordsman, treatment process, temperature and humidity and other factors. Generally speaking, the average oil extraction rate of oil beans is about 30%, and there are higher varieties that reach more than 40%, and lower varieties even less than 20%.

Therefore, the amount of oil that can be squeezed from one catty of oil beans is between catties (unit conversion: 1 catty = kilogram). It should be noted that this is only an approximate oil extraction rate, and the actual oil extraction rate is also affected by many hydrogliding environments and processing conditions, and the specific situation of each oil extraction may be different.
