Q: What is a oil refining equipment? what’s the effect?
A: Crude oil obtained by physical pressing or other methods is mixed with suspended particles, water, phospholipids, proteins, free fatty acids, organic or inorganic impurities, which affect the edible value and storage safety of edible oil. When you use an oil press to produce oil, the oil cannot be directly consumed. The oil must be refined. The purpose of refining is to remove useless harmful impurities in edible oil, storage oil and industrially produced oil.
The edible oil refining equipment provided by Benteng Machinery is suitable for refining various raw oils, such as rice bran oil, peanut oil, soybean oil, sunflower oil, palm oil, palm kernel oil, cottonseed oil, olive oil, mustard oil, coconut oil, etc. In addition, it can effectively extract impurities contained in edible animal oils, such as seal oil, fish oil, chicken oil, etc.
The edible oil refining equipment consists of a refining tank, a vacuum dehydration tank, a decolorization tank, a vacuum pump, an oil pump, an alkali tank, a metering tank, and an electrical control cabinet. It is equipped with automatic temperature control devices, vacuum dehydration, heat insulation devices and feed buffer devices. Realize the functions of degumming, deacidification, decolorization and drying of crude oil.
This crude oil refining equipment is used for crude oil cleaning, including degumming and deacidification, decolorization, and deodorization. Then the refined oil reaches the national edible oil standard and can be eaten directly, and can be directly filled and sold to small processing and oil processing plants.
Q: What is the working principle of the oil refining equipment?
The specific edible oil refining process is as follows.
Dephosphorization and degumming
Hydration and degumming is a very important step. Hydration and degumming is a hydrophilic gel that utilizes insoluble impurities such as phospholipids. The amount, temperature and speed of water added to phosphoric acid are all important. The glue settles through the principle of flocculation when glue meets water. Add a predetermined amount of hot water or an aqueous solution of diluted alkali, salt, phosphoric acid electrolyte in the hot crude oil under stirring to make one of the hydrogels gather insoluble impurities, and then separate. This physical, chemical or physical chemical method to remove colloidal impurities in crude oil is called degumming.
A certain amount of hydrogenated phosphoric acid is added, and after the reaction, the non-hydratable phospholipids in the oil are converted into hydrated phospholipids. In this way, the phospholipid content is greatly reduced, and a better dephosphorization effect can be achieved.
Crude oil may contain most of the free fatty acids. After refining, the fatty acid sodium salt does not dissolve in the oil, but precipitates as flocs. Sodium hydroxide and fatty acid sodium soap are produced, and the reaction speed is fast. The obtained sodium soap surfactant has strong adsorption and absorption capacity, which can bring a considerable amount of impurities such as proteins, pigments, phospholipids and substances with hydroxyl groups into the sediment and suspend And even the fluffy soap groups may be taken away,
In this stage, sodium hydroxide (NaOH) is used to neutralize free fatty acids in crude oil. During this process, some soap will be produced and separated from the oil. Lye can not only neutralize free fatty acids, but also neutralize excess phosphoric acid. In the batch, semi-continuous edible oil refining process, we use the method of sedimentation and separation of soapstock.
In addition to effectively removing oily pigments, this process of decolorization can also reduce phospholipid content, peroxide value, soap dosage, and oil-containing metal ion content to improve color, flavor and enhance oxidation stability. The most commonly used method is activated clay adsorption decolorization, that is, clay has a strong selective adsorption of this substance. Under certain conditions, oil-soluble dyes or impurities such as pigments dispersed in oil with colloidal particles can be removed to improve The color of the oil.
The smell of crude oil is not very good, which will affect the storage and sales price of edible oil. It can be achieved through high temperature and high pressure. We usually use direct steam to remove the peculiar smell of crude oil. The oil also contains 0.5% water, which can be removed by the high temperature in the deodorizer.

1) The linear structure is simple and easy to install and maintain.
2) The electrical parts and operating parts adopt advanced Chinese famous brand components.
3) Fully automatic continuous work
4) The operation has a high degree of automation, a high degree of intelligence, and no pollution.
5) Environmental protection, low noise, low power consumption
Q: Do you need a oil refining equipment in every oil production line? How should I choose?
A: No, it’s not that the better the refining line is, the more work sections there are. This is not necessary. This must be explained clearly to everyone so as not to spend more money.
Different edible oils require different refining stages, so refining equipment does not have to be purchased. For example, peanut oil can directly become national first-class oil as long as it is decolorized and deodorized, while rapeseed must undergo dephosphorization and degreasing. Cottonseed oil needs to be de-molded, corn oil only needs to be decolorized, de-sugar and degummed. Different oil treatment methods are different, and some sections are meaningless. When purchasing a full set of oil extraction equipment and refining equipment, we must understand our purpose and come up with a procurement plan that suits our production needs.
