The purpose of edible oil refining is to remove impurities unwanted and harmful impurities from crude oil to obtain refined oil that meets certain quality standards. These impurities not only affect the edible value and safe storage of oil products, but also bring difficulties to deep processing.

Whether in terms of the quality of oil or the application of refined edible oil, Refined oils after removal of impurities have many advantages, I will give you a detailed introduction.
1. Refined edible oil looks better
Refining includes decolorization and deodorization steps, which can remove the peculiar smell and the pigment of crude oil, it make the oil clear and bright and improve the taste of oil. In the refining process, according to the type of oil, the wax in the oil is sometimes removed, so that the finished oil is more transparent and avoids the turbidity caused by wax precipitation after a period of storage.
2. There are some high value by-products in the edible oil refining process

The process of oil degumming can produce phospholipid, which is a high value-added product and can be used as emulsifier and stabilizer in many foods.
Some oil refineries also separate fats according to the melting point of fatty acids. Palm oil producers, for example, often divide palm oil into palm stearin which has a higher melting point, and palm soft fat which has a lower melting point. The former is solid at room temperature, and the latter is liquid at room temperature, so that it can meet the needs of more different processing scenarios.
3. Food safety needs
The refining process removes harmful impurities and toxins from raw materials, making refined oils generally safer. Cottonseed oil is a case: cottonseed oil contains gossypol, which is reproductive toxic and therefore must be refined to make refined cottonseed oil that is safe to eat.

Three types of edible oil refining machine photo
Option1: Batch type (intermittent) edible oil refining equipment
Batch type (intermittent) edible oil refining equipment, it is suitable for small capacity edible oil refinery plant, like:1TPD, 2TPD, 5TPD, 10TPD, 15TPD, 20TPD, etc, which contains Degumming, Neutralizing, Decolorization and Deodorization section, and all refining processes are carried out in batches.
Option2: Semi continuous edible oil refining equipment
Semi continuous edible oil refining equipment, it is suitable for medium capacity edible oil refinery plant, like: 20TPD, 30TPD, 40TPD, 50TPD, etc, This kind of edible oil refining machine is very easy to operate, when the equipment is successfully installed, the customer's workers only need a short time professional training can operate normally.
Option3: Fully continuous edible oil refining equipment
Fully continuous edible oil refining equipment, It is suitable for large edible oil refinery with daily processing capacity of 50-600T. The equipment can help you realize the full automation of refined cooking oil production, saving a lot of labor and time costs.
The above edible oil refining equipment selection scheme is for your reference. In addition, Henan Glory Company can design and provide you with the most suitable edible oil refining scheme according to your actual production needs. If you need edible oil refining equipment, please feel free to contact us.
After oil clarification (for pressed oils), the oil can be refined as shown below.
The crude oil is then transferred either to special degumming in the physical refining route, to water degumming, or directly to neutralization in the chemical refining route. In the chemical refining route, free fatty acids undergo a reaction to create aqueous soap, which is removed from the oil in centrifuges. The physical refining route removes only some impurities (mostly phosphatides, also known as phospholipids or gums) from the oil. Some oils, such as sunflower and corn, go through a dewaxing step to achieve the prescribed cold stability, that is, to be able to retain clarity at low temperatures. The bleaching process removes additional impurities, such as metals, soap residues and color components. Finally, to prolong shelf life, the oil undergoes deodorization to initiate thermal decomposition of residual color, any components lending unwanted taste, and peroxides. Volatile compounds (mostly fatty acids) are removed via steam stripping at about 240 ' 260°C under vacuum. Fatty acid distillate is produced as a valuable by-product in the physical refining route, much less so for the chemical refining route.
Last but not least, take advantage of our Utility Process Systems to further cut operational costs in your edible oil refinery plants by reducing utility expenses ' whether power, process water, steam, fuel and/or cooling media.
