Edible Oil Filter
Removes suspended solids from crude oil after pressing so it is clear enough to sell, store or refine. Plate and frame, leaf, bag and polishing filters.
- Rating
- Sized to crude oil flow (kg/h or tonnes per day) and solids content
- Versions
- Plate and frame · Leaf filter · Bag filter · Polishing filter
- Best for
- Oil mills and press operators that sell filtered pressed oil or feed crude oil to a refinery
- Filter type matched to solids load and target clarity
- Coarse and fine stages combined where needed
- Closed designs to reduce oil oxidation and handling
- Filter cake can often return to the press or cake line
Short answer: An edible oil filter removes the fine solids that crude oil carries out of the press, so the oil can be sold as filtered pressed oil, stored, or sent to a refinery. The solids content, the oil viscosity at its working temperature, how fine the filtration must be and how you discharge the filter cake decide which filter suits you.
How it works
Crude oil from the press usually goes into a settling tank first, where heavier particles sink. The partly clarified oil is then pumped into the filter.
In a plate and frame filter, plates covered with filter cloth are clamped together; oil is pumped into the chambers between them, the solids build up as a cake on the cloth, and clear oil runs out through channels in the plates. When the cake fills the chambers, the press is opened and the cake removed. A leaf filter works on the same principle inside a closed vessel, with vertical leaves that can be cleaned by vibration or back-flushing. Bag and cartridge filters catch remaining fine particles in a replaceable element.
Pressure rises as the cake builds, so filter area and cleaning interval are sized together.
Which configuration fits
| Form | Suits | Watch out for |
|---|---|---|
| Plate and frame | Small and medium mills, mixed oils | Manual cake removal and cloth cleaning |
| Leaf filter | Larger, more automated plants | Higher purchase cost |
| Bag filter | Low solids, second stage | Bags blind quickly with heavy solids |
| Polishing combination | Bottled pressed oil needing high clarity | Two stages to maintain |
What we need from you to quote
- Oil types and estimated solids after pressing or settling
- Oil temperature at filtering
- Throughput measured on crude oil flow (kg/h or tonnes per day)
- Target clarity, or whether oil goes on to refining
- How the filter cake will be used
- Batch or continuous operation and available space
Where it sits in a line
The filter follows a screw oil press or hydraulic oil press. Filtered oil is filled with a liquid filling machine or sent to an edible oil refining line. It is also part of a sesame oil production line.
Common configurations
- Option A
Plate and frame
filter cloths between plates hold the solids; low cost and flexible, cleaned by hand.
- Option B
Leaf filter
filter leaves in a closed vessel; less manual handling, solids discharged by vibration or flushing.
- Option C
Bag filter
replaceable filter bags in a housing; simple for low solids or as a second stage.
- Option D
Polishing filter combination
a coarse filter followed by a fine cartridge or bag for a bright, clear oil.

Frequently asked questions
Which filter suits pressed oil from a small mill?
Many small and medium mills use a plate and frame filter press after a settling tank, sometimes followed by a bag or cartridge filter for a brighter oil. Leaf filters suit larger, more automated plants.
Should oil be warm when filtering?
Warm oil is thinner and filters faster, but too much heat speeds oxidation. The best temperature depends on the oil type; we recommend a range for your oil.
What happens to the filter cake?
It still contains oil. Many mills return it to the press with fresh seed or mix it with press cake. Your plan for it affects the filter type and layout.
