10T/D Edible Oil Refinery Plant

Why Refining Edible Oil?
The crude oil obtained from oil expellers or solvent extraction contains impurities such as phosphatides, free fatty acids (FFA), pigments, off-flavor, etc. Oil Refining is a series of process to remove these impurities. After refining, the flavor, color and smell of oil is improved, the stability is improved which is good for long time storage, the smoke point of oil is increased. We provide 10T/D edible oil refinery plant for you. Besides, 1-5T/D edible oil refining line and 20T/D edible oil refining line are also available.
Wide Application of 10T/D Edible Crude Oil Refinery
1. The 10T/D crude oil refinery can refine various kinds of oil, such as peanut oil, sesame oil, soybean oil, rapeseeds oil, sunflower oil, cotton seeds oil, palm kernel oil, flax seeds oil, camellia oil, hemp seeds oil, castor seeds oil, mustard seeds oil, etc.
2. The complete oil refining plant can work independently or together with whole oil production line. The capacity can be customized. We provide two engineers after your receipt of equipments for on site installation, debugging and training.

* Steam Generator: produce steam for the workshop (1 set)
* Heat Conduction Furnace: provide enough heat for the refining sections (1 set)
* Other Auxiliary Equipments: Air compressor, pumps, filters, etc.
Process of 10T/D Edible Oil Refining
1. Degumming
Degumming process use hot water to hydrate phosphatides and get them removed. The oil then go through heating, drying and cooling. Before degumming, a plate oil filter is utilized to reduce the content of mechanical impurities, and further avoid emulsification or too much neutral oil contained in foots. The hydrated oil foots can be dried for lecithin, which is used for food additives and feed additives.


2. Neutralizing
The purpose of neutralizing is to remove free fatty acids (FFAs). Accompanied with continuous stiring, caustic solution (NaOH) are pumped into the degummed oil to react with free fatty acids and form soapstocks, which settle down and are pumped into the soapstocks tank for recycling. The oil is pumped into water tank and washed by hot water for 2-3 times till the waste water is clean, then dried and cooled. The byproduct soapstock can be used for manufacture of soaps and biodiesel, added in livestock feed, or treated for the fatty acids it contains.


3. Bleaching
Bleaching process use bleaching earth to remove pigments in oil. Degummed and neutralized oil are pumped into this system, preheated and then mixed in the bleaching tank under vacuum state with bleaching earth to adsorb pigments. Then the mixture is dried, and filtered to remove clay.


4. Deodorizing
The purpose of deodoring is to remove odor substances(mainly FFA) that are naturally present in the oil or created during processing. The bleached oil is subjected to steam distillation under high temperature and high vacuum to evaporate all odor substances, and then cooled and filtered to remove metallo-chelate. Fatty acids in the volatile gas are trapped by the fatty acids trap, then cooled and stored in the fatty acids tank.

1. Every process should be strictly controlled so that to do well to the next steps.
2. Bleaching process is not to be omitted even if the color of oil is shallow.
