Refining

The refining process is meant to better the appearance, odor, flavor, among other vegetal oil properties, removing components that worsen its quality. The process steps depend on the quality of the gross oil available and the final oil desired utilization. FILTRATION
Realized through a filter press, removes impurity and the mechanical extraction process resulting fines (raw material particles), bleaching (bleaching soil that absorbed dye), winterization (waxes) and deodorization (oil final polishing). DEGUMMING
Degumming can be done with water and/ or acid application. Treatment with phosphoric acid is the first step of the refining, particularly important the soya oil. It is also applied to other raw materials, like cotton and corn, in some cases it is not indispensable, but betters considerably the final product and reduces the refines losses by emulsion. After treated, the degummed oil is transferred to neutralization. NEUTRALIZATION
This process consists of lowering the oils acidity, eliminating free fatty acids through adding alkaline solution (caustic soda and water). Separation can be through decanting (in small scale) or centrifugation. The oil leaves de neutralization centrifuge and goes to the first wash tank. If the oil requires double neutralization, it follows to the second neutralization tank, where the desired values are reached. WASHING
After neutralization, the oil presents soap remaining that must be removed through hot water washing, in two steps that guarantee complete cleaning. DRYING
The oil drying consists of reducing the percentage of water in the oil, guaranteeing a minimum value for a good progress in the continuation of the refining process and/or commercialization. BLEACHING
Bleaching is the process through which it is removed part of the oil’s pigments, specially the yellow and red. Other colors such as blue are also reached, but with less intensity, such as metal traces, vitamins and oxidations.. WINTERIZATION
Winterization is the process by which crystallizable waxes and stearines contained in the oil are removed. This process is indicated for oils like: cotton, corn, rice and sunflower. DEODORIZATION
The deodorization process consists of physically refining vegetal oils, using only heat, direct steam and high vacumm to remove the free fatty acid and odoriferous substance. This process can be discontinuous (small daily production) or continuous (large daily production). CONTINUOUS REFINARY:
Refining unity for several vegetal oils with the processes of neutralization, bleaching, winterization and deodorization, all of it in continuous flow and automatized. DISCONTINUOUS REFINARY:
Refining unity for several vegetal oils with neutralization, bleaching, winterization and deodorization processes, all in batches (per load), composed by the sections of: neutralization, winterization and deodorization.
