Oil filtering is an essential process in a cooking oil production plant since oil filtering process can effectively remove impurities and unwanted particles contained in the crude oils, and all these physical obstances can have negative effects on final produced cooking oil. But, how to choose the right oil filter machines and oil filtering techniques for your cooking oils? Just keep reading and get the right answers. And, if there are any questions, just contact us without hesitation!
How to Filter Impurities during Cooking Oil Production?
Edible oil filtering is a process that removes impurities and contaminants from the oil, which involves passing produced crude oils through a filter medium, which traps the impurities and allows the oil to pass through. The filter medium can be made of different materials such as paper, cloth, or a membrane. Generally, paper filters are commonly used for small scale oil filtering, while cloth filters are used for large scale oil filtering. Membrane filters are used for ultra fine oil filtering, where a high level of purity is required. Depending on required purity level of cooking oils, oil filtering process can be completed before or after cooking oil refining process. (Read more: Edible Oil Refining Technology >>)
Cold Filtering Factory Setup for Peanut/Groundnut Oil Production
Before cooking oil refining process, crude oil filtering process is mainly designed to remove large particles such as dirt, debris, and leaves. After cooking oil refining process, oil filtering process is mainly designed to remove the finer impurities such as residual soap, phospholipids, and pigments. And, these two different oil filtering processes are usually completed by different oil filter machines. The type of oil filter machines for cooking oil production will mainly depend on the oil type and the desired level of purity.
Edible Oil Filter Machines at Factory Price
There are different types of oil filter machine that can be used for filtering edible oils, depending on the volume of oil to be filtered, the type of oil, and the desired level of filtration. The most hot sale oil filter machines used for various cooking/edible oil production has:
- Plate and Frame Oil Filter Machines
These are simple oil filtering machine that consist of a series of plates and frames with filter media in between them. The oil is passed through the filter media, which removes impurities and particles. Plate and frame oil filters are commonly used for small scale oil production, like small scale oil production line, etc, and are relatively inexpensive.

- Pressure Leaf Oil Filter Machines
Pressure leaf oil filter machine consist of a series of metal frames with filter media in between them. The oil is passed through the filter media under pressure, which removes impurities and particles. Pressure leaf filters are more efficient than plate and frame oil filters and are commonly used for small or medium oil production plant .

- Centrifugal Oil Filter Machines
These oil filter machines use centrifugal force to separate impurities and particles from the oil. The oil is fed into a rotating drum, which separates the heavier impurities from the lighter oil. Centrifugal oil filter machines are relatively expensive but are very efficient and are commonly used for complete oil extraction plant.

- Membrane Oil Filter Machines
These filters use a very fine filter media, such as a membrane, to remove particles as small as 0.2 microns. The oil is passed through the membrane under pressure, which removes impurities and particles. Membrane filters are very efficient but are relatively expensive and are commonly used for high value oil produciton such as, olive oil.
