Short answer: An edible oil refining line removes gums, free fatty acids, colour and odour from crude oil so it can be sold as refined cooking oil. The type of oil and its crude analysis, together with your target quality, decide which units are needed and whether batch, continuous or physical refining fits; steam, vacuum and by-product handling then shape the plant.
How it works
- Degumming – water or acid is mixed into warm crude oil to make phospholipids (gums) separable; they are removed by settling or a separator.
- Neutralising (chemical refining) – alkali reacts with free fatty acids to form soapstock, which is separated and washed out.
- Drying – oil is dried under vacuum.
- Bleaching – bleaching earth is mixed into the oil under vacuum to absorb pigments and traces, then filtered off.
- Deodorising – oil is heated under deep vacuum while steam strips volatile odour compounds; in physical refining this step also removes free fatty acids.
- Cooling and polishing – refined oil is cooled and passed through a polishing filter before storage.
Some oils need extra steps, such as winterising to remove waxes so the oil stays clear when cold. Each step also creates a by-product or waste stream, from soapstock to spent bleaching earth, so the refinery layout includes space and handling for these from the start rather than as an afterthought.
Which configuration fits
| Form | Suits | Watch out for |
|---|---|---|
| Batch chemical refining | Smaller volumes, several oil types | More labour; batch-to-batch variation |
| Continuous refining | Larger daily volumes of one oil | Higher investment; steady crude supply needed |
| Physical refining | Oils with low phosphorus after degumming, such as palm | Degumming must be thorough |
What we need from you to quote

- Finished oil specification and target market
- Throughput measured on crude oil input (tonnes per day)
- Steam, cooling water, power and water treatment available
- Plans for soapstock, spent earth and fatty acid distillate
- Delivery point: refined oil tank or a filling section
Where it sits in a line
Crude oil comes from a screw oil press and edible oil filter, or is bought in. Steam can be supplied by a food steam generator for smaller plants. Refined oil goes to storage and a liquid filling machine.
Common configurations
- Option A
Batch chemical refining
each step runs in tanks batch by batch; flexible for smaller volumes and several oil types.
- Option B
Continuous refining
oil flows through each unit without stopping; suits larger daily volumes of one oil type.
- Option C
Physical refining
free fatty acids are removed by steam distillation in the deodoriser instead of with alkali; needs well-degummed oil.

Frequently asked questions
Chemical or physical refining?
Chemical refining uses alkali to remove free fatty acids and is tolerant of many crude oils. Physical refining removes them by distillation, which reduces soapstock and oil loss, but only works well when gums and phosphorus are removed thoroughly first. Your crude oil analysis decides.
What utilities does a refinery need?
Steam (often at higher pressure for deodorising), a vacuum system, cooling water, compressed air, power and chemical storage. Requirements depend on the route and capacity, and we list them in the proposal.
Can one line refine different oils?
A batch line can switch oils with cleaning between them. Continuous lines are usually designed around one main oil, with settings adjusted for similar oils.
