Each section introduction of our crude oil refining process

Batch Type Edible Oil Refinery

Crude oil refining process usually includes the following sections: Degumming, Neutralization, Bleaching, Dewaxing and Deodorization. The process of removing these impurities after oil extraction section is called oil refining. The crude oil obtained either from expellers or solvent extraction plant contains impurities, which must be removed to make the oil edible, more palatable and stable against rancidity upon storage.

De-gumming, alkali refining and water-washing section of crude oil refining process
After filtration, the pressed crude oil will be pumped into the refining pot.Refining pot is the main equipment in crude oil refining process. To add phosphoric acid make the nonhydratable phospholipids change into hydrophilic phospholipid, at the same time, dissolve the iron ion in the oil in the high acid process, add seldom alkali produce soapstock and the absorption effect which can remove the impurity in the oil, add water for washing, the washing discharge soapstock which will be recycling, and the washed oil will go into temporary tank for store.  

Continuous drying section of crude oil refining process
After steam heating, the washed oil goes into the continuous drying tower, and the water in the oil will be vaporization through the high vacuum. The dried oil will be pumped into the temporary storage tank before decolorization from the bottom of continuous drying tower.

Continuous decolorization section of crude oil refining process
Adding bleaching earth to the oil for fully mixing and heating under the vacuum condition in crude oil refining process, which make the tiny pigment granules suspended in the oil to be absorbed on the bleaching earth, and then it will be removed by the leaf filter.

Continuous deacidification, deodorization section of crude oil refining process
Soft tower deacidification and deodorization technology represents the most advanced deodorization technology at present in crude oil refining process, can remove the free fatty acid and stink composition in the oil by this integrated structure tower.

The process flow: Most heat of the qualified de-colored oil will be recycled by the high efficiency heat ex-changer. Then through the conduction oil or high pressure steam heat the oil to the required temperature and enter the deodorization tower.The deodorization tower is the main equipment in crude oil refining process. The deodorization tower is integrated structure, which’s upper layer is structure padding that main function is to remove stink composition such as the free fatty acid etc, and which’s under layer is plate structure that main function is hot de-coloring to make the oil quality more stable. The oil came from the deodorization tower will be storied after a series heat exchanging and cooling. The volatile substances such as fatty acid came from the deodorization will be collected by the padding catcher fully as the by-product.

Continuous dewaxing section of crude oil refining process
Dewaxing is an important step for improving the quality of the edible oil in crude oil refining process. The wax effect the palatability of the oil, so the propose of de-waxing is improving the oil palatability and the sensory properties such as transparency and brightness. Different oil has different wax content, and also the dewaxing is necessary for the oil quality such as corn germ oil, sunflower oil, rice bran oil, flaxseed etc.
 
Our crude oil refining process machinery technical highlights
1.More mechanization and automation, less human labor and cost.
2.More advanced technical configuration, such as continuous drying, continuous decoloration, continuous deacidification, continuous deodorization, continuous de-waxing.
3.Automatically metering and feeding for bleaching earth, high vacuum, saving steam and energy, reducing the crude oil refining process machinery cost.
