Soybean Oil Refining Machine Oil Refining Process Groundnut Oil Refining Machine

Soybean Oil Refining Machine Oil Refining Process Groundnut Oil Refining Machine is a general term for the removal of solid impurities, free fatty acids, phospholipid, colloid, wax, pigment and odors in vegetable oils. The presence of impurities contained in crude oils not only affects the use value, the safety storage of crude oil, but also cause difficulties for the deep processing crude oils. Edible oil refining is not only removes all the impurities out from the crude oils, but also refines harmful impurities, such as, gossypol, protein, lecithin, mucus, water and more. In this way, the edible oils can have better storage, industrial applications and cooking purpose. However, some beneficial substances, such as tocopherol, sterol and more, will be maintained.

Main Equipments

1)Neutralization section

After heating, oil is then carried out with caustic soda to saponify the fatty acids and to ease the removal of the precipitate in centrifugal separator. The contact is made in mixer, and then a short contacting time is allowed in reactor. The lye saponifies the fatty acids in the oil and forms soap stock, which is removed together with the gums and the excess caustic solution. The caustic soda solution is coming from the caustic dosing device. The neutralized oil still contains small amounts of residual soap, which must be minimized before further processing. Some soft hot water (usually boiler treated water or steam condensates) is added to the oil in mixer and is then sent to washing centrifugal separator, where the residual soap is separated from the oil. The oil is dried under vacuum as the residual moisture must be reduced. The oil is first heated in a plate heat exchanger, by means of low pressure steam. The oil is then dried under vacuum in the dryer. of the bleaching section with its vacuum group. Then the oil is sent to the bleaching section by pump.

2)Bleaching section

Crude oil is fed to the oil-earth mixer through heat exchanger and heater. Prior to bleaching, the bleaching earth is dosed into the oil by means of a volumetric dosing system. The bleaching earth hopper is installed above the oil-earth mixer and assures continuous operation of the plant. The hopper can be automatically filled by means of the pneumatic earth feed assembly. After bleaching earth dosing, the oil flows into the bleacher. After bleaching, the oil-earth mixture is sent to filter and security filter by means of pump. After the filtration operation, oil recovery from spent cake is done by steam blowing and the spent cake is discharged and evacuated through a chute to a disposal container.

3)Deodorization Section

The bleached oil is first de-aerated in a buffer tank, It works at the same vacuum as the deodorizer and acts also as buffer feed capacity. After deaerator, Oil is sent by pump to be preheated by the heat exchange with the deodorized oil to a temperature between 190° and 210°C, and deodorized oil is cooling to a temperature of about 135°C. Finally, the oil is heated by conduction oil or high pressure steam until it reaches the final deodorizing temperature. After deodorization, the oil is cooled with feeding oil, polished, and pumped into storage tank.
This cooling and contact combined with a lower velocity will allow catching nearly all fatty acids distillates present in the gas flow.
