QIE GROUP supplies soybean oil refinery plants for processing crude soybean oil into refined edible oil. The refining system integrates degumming, deacidification, bleaching and deodorization to remove gums, free fatty acids, pigments and unwanted odors.
Depending on the required processing capacity, crude oil quality and finished oil specifications, the plant can be configured as a batch, semi-continuous or continuous refining system. We also supplies vegetable oil refining equipment for processing different types of crude vegetable oils.
The main refining stages include:
The specific process route is determined by the crude oil's phosphorus content, free fatty acid level, impurities and target oil quality.
The degumming system removes phospholipids and other gum impurities from crude soybean oil. Water or acid-assisted treatment can be selected according to the oil's characteristics and the required refining process. Separation equipment removes the resulting gums from the oil.
Deacidification reduces free fatty acids in soybean oil. Depending on the refining configuration and crude oil quality, this stage can use alkali neutralization or physical refining through steam stripping under high vacuum.
For soybean processing plants using solvent extraction, the crude oil produced by the extraction section can be sent to the refining system for further treatment. Learn more about soybean oil solvent extraction equipment.
The bleaching system mixes soybean oil with suitable bleaching earth under controlled conditions, typically under vacuum. The adsorbent helps remove pigments and certain residual impurities, followed by filtration to separate the spent bleaching earth.
Deodorization uses high-temperature steam stripping under high vacuum to remove volatile odor compounds and other undesirable substances. Operating conditions are selected according to the oil quality and finished product requirements.
A soybean oil refining system may include the following equipment, depending on the selected process:
The final equipment list and configuration are confirmed during project design.
We offers different soybean oil refining configurations to suit different production requirements.
| System Type | Suitable Applications |
|---|---|
| Batch refining | Smaller-scale production requiring flexible operation |
| Semi-continuous refining | Projects seeking a balance between operating flexibility and throughput |
| Continuous refining | Industrial plants requiring steady, continuous processing |
The appropriate system depends on daily processing capacity, crude soybean oil quality, operating schedule, utility availability and investment budget. The refining method should also be selected according to the oil's characteristics and target product specifications.
For projects requiring a complete soybean processing setup, we can also provide an integrated soybean oil production line covering pretreatment, oil extraction and refining.
Before selecting soybean oil refining equipment, consider the following factors:
Providing these details helps determine a suitable process route, equipment configuration and level of automation for the project.
For larger projects integrating soybean pretreatment, solvent extraction and refining, understanding the investment requirements of a 300 TPD soybean oil plant can help with preliminary project planning.
A typical plant includes degumming, deacidification, bleaching and deodorization equipment, together with the necessary separation, filtration, heating and vacuum systems.
Yes. Physical refining can be considered when the crude oil quality and pretreatment results meet the requirements of the selected process. The final choice should be based on feedstock analysis and engineering evaluation.
Some equipment may be adaptable to other vegetable oils, but pretreatment requirements, process conditions and equipment configurations can differ by oil type.
QIE's experience in soybean oil processing includes large-scale integrated projects, such as a 600 TPD soybean oil processing project.
