Soybean oil refining transforms crude soybean oil into purified edible oil suitable for consumption and a range of industrial applications. The process is designed to remove or reduce impurities that may affect flavor, color, stability and storage performance, including phospholipids, free fatty acids, pigments, waxes and volatile compounds.
| Process stage | Primary purpose | Typical process function |
|---|---|---|
| Degumming | Remove phospholipids and gum-forming impurities. | Water or dilute acid hydrates gums so they can be separated, often by centrifugation. |
| Neutralization | Reduce free fatty acids and improve oil stability. | An alkali such as sodium hydroxide reacts with free fatty acids to form soapstock for separation. |
| Bleaching | Reduce pigments, trace metals and residual impurities. | Bleaching earth or activated clay adsorbs unwanted compounds before filtration. |
| Deodorization | Remove volatile compounds, odors and residual free fatty acids. | Steam distillation under vacuum helps produce oil with a more neutral taste and odor. |
| Winterization (optional) | Improve clarity during low-temperature storage. | Cooling promotes wax crystallization, which is then removed through filtration. |
Appropriate soybean oil refining helps control acidity, color, odor and unwanted impurities. It also supports the production of oil with improved storage stability and a quality profile suited to cooking, food processing and other intended uses. The actual process configuration should be selected according to crude oil characteristics, required product specifications and local operating conditions.
The equipment route can be considered in relation to the oilseed, crude oil condition, extraction method and target refined oil quality.
Pressing, extraction, refining and supporting equipment can be coordinated as part of an integrated oil processing project.
Qi'e provides project support covering installation, commissioning and technical guidance to help connect equipment with the planned process.
Depending on the project scope, Qi'e Grain and Oil Machinery Co., Ltd. supplies and supports a range of oil processing equipment and production lines, including:
