Mustard oil oil refineries refining machine coconut virgin oil machine russian

• The crude vegetable oil from two ways of extracting, oil pressing and/or solvent extraction, will be pumped into oil refinery units to produce cooking oil at various grades.

• The main equipment of oil refinery is various kinds of vessels and tanks carrying on different tasks with additives.

• These tasks may include sedimentation/filtering, neutralization (removing free fatty acid), degumming, decolorization (bleaching), deodorization, especially the dewax process is necessary, more wax would destroy the quality of sunflower oil.

  Sunflower oil is the most widely used oil due to its high linoleic content which is considered nutritionally positive. The kernel accounts for 70% of the seed and the oil content is about 40%-45% in the seeds.

   

  Hydration Deguming & Alkali Refining Deacidification Process:

Washing:  There is still about 500ppm soap in the neutralized oil from the separator. To remove the remaining soap, add into the oil about 5~8% hot water, with water temperature 3~5 °C higher than the oil generally. To achieve more stable washing effect, add phosphoric acid or citric acid when washing. 

The remixed oil and water in the mixer is heated to 90~95°C by the heater, and then enters the wash separator to separate the remaining soap and most water. The water with soap and oil enters into oil separator to separate out oil in the water. Further catch the oil outside, and the waste water is discharged to the sewage treatment station.  in the sunflower seed oil refining machinery manufacturer.

Vacuum drying stage: There is still moisture in the oil from the wash separator, and the moisture will affect the stability of the oil. So the oil at 90°C should be sent to vacuum drier to remove the moisture, and then the dehydrated oil goes to the decoloring process. Finally, pump out the dry oil by canned pump. for the sunflower seed oil refining machinery manufacturer.

Continuous Refining Deodorizing Process

The qualified decolored oil enters into the spiral plate heat exchanger to recover most of the heat, and next goes to high pressure steam heat exchanger to be heated to the process temperature (240-260°C) and then enters the deodorization tower. The upper layer of combined deodorization tower is the packing structure which is mainly used to remove the odor producing components such as free fatty acid (FFA); the bottom layer is the plate tower which is mainly for achieving the hot decoloring effect and reducing the peroxide value of the oil to zero. Oil from the deodorization tower enters into the heat exchanger to recover most of the heat and makes further heat exchange with crude oil, and then is cooled to 80-85°C through the cooler.
