3 signs

You are losing money:

Short storage period

Oil goes bad in 15 days in tropical climate

Oil loss

Conventional oil filter loses 5-10% of oil

Frequent downtime

Cleaning required every 2-3 hours of operation

Centrifugal Oil Filter Machine

The centrifugal oil filter removes fine particles and residues through high-speed spinning—no need for filter cloths. It’s ideal for edible oil producers seeking fast, efficient clarification after pressing. Especially useful in daily small-batch operations, this filter ensures clean, impurity-free oil with minimal maintenance.

Vacuum Oil Filter Machine

Vacuum oil filters use vacuum negative pressure technology to remove excess water, impurities and fine particles from crude oil. This method can improve the purity, stability and shelf life of vegetable oils and is suitable for hot-pressed and cold-pressed oils. It is a good choice for small oil mills that need cleaner, clearer oils without relying on industrial-scale systems.

Plate and Frame Filter Press Machine

The plate and frame filter press delivers deep filtration using filter cloth and mechanical pressure. It is ideal for batch processing and oil mills with high precision requirements, especially for processing viscous or sediment-rich oil products. This robust setup is widely used in village-level or semi-commercial oil production environments.

Pneumatic Oil Filter Machine

Our pneumatic oil filter uses air-driven pressure to push oil through multi-stage filter layers, delivering fast, high-volume filtration with stable results. Its compact design, ease of operation, and continuous output make it ideal for mobile processors or commercial users who need efficiency without electrical complexity.

Refinery Equipment&Machine

An edible oil refining machine provides an extra level of purification after initial oil pressing. It removes residual gums, free fatty acids, and other trace impurities, improving oil clarity, taste, and shelf life. This precision filtering step is ideal for small oil mills or local brands targeting premium-grade edible oil markets. GQ-Agri’s compact refining units offer a practical solution for micro oil processors needing higher quality without costly industrial setups.

Improve oil quality and reduce sales resistance.

When selling edible oils, transparency and shelf life are crucial. Consumers generally associate visible purity with safety and quality. Our oil filter helps farm oil mills and edible oil entrepreneurs convert the pressed crude oil into high-quality edible oil that can be directly marketed, thereby gaining more customer trust and higher pricing potential.

Reduce impurities: Reduce impurities, foam and moisture in the first pressed oil. Most buyers tend to buy transparent edible oil without impurities.
Improve shelf life: Extend the storage shelf life of finished oil, reduce storage costs and the risk of deterioration.
Guarantee profit: Traditional manual sedimentation or secondary heating filtration will cause 5-10% oil loss. Professional edible oil filter machine can reduce profit loss.
Improve efficiency: Professional Oil filter machine can reduce the number of shutdowns for maintenance & cleaning, ensuring that everything is carried out according to the established daily production plan.

Why is Oil Filtration Critical in Edible Oil Production?

After the seeds are pressed and oil is extracted, but before the final product is bottled, one crucial step stands between raw oil and market-ready edible oil: filtration. In small-scale oil production—whether on a farm, in a village oil workshop, or by an independent oil processing business—oil filtration is not just optional; it’s essential.

If you have been to an oil pressing site, you can see that unfiltered freshly pressed vegetable oil is turbid and contains fine crop residues, fibers, moisture and other impurities. These impurities directly affect the clarity, shelf life and health issues of the oil. In the past, people could only use the method of sedimentation and secondary heating to remove some impurities, which required a lot of time, energy and even waste of oil. Now, a professional Oil filter machine comes on the scene – it is designed to purify freshly squeezed oil and transform it into clear, stable and easy-to-sell edible oil. Modern oil filters have several key benefits:

Remove solid particles and moisture to prevent rancidity.
Improve the transparency and color of the oil to make it more visually attractive.
Improve storage stability by reducing the risk of oxidation.
Improve the overall grade of oil products and increase their commercial value.
Meet basic food safety and hygiene standards.
Avoid customer complaints.

Whether you are producing peanut oil, sunflower oil, sesame oil or palm kernel oil, reliable oil press filters help farm oil presses, oil pressing companies, and even edible oil processors who bottle and retail edible oil to make the hard-earned oil cleaner, safer, and easier to sell. It is more than just a machine, it is a powerful assistant for any business that is serious about producing quality oils.

Types of Oil Filter Machines We Offer for Small and Medium Oil Mills.

We know that any entrepreneur who runs a small or medium-sized oil mill comes from a farm, and choosing Oil Filter Machines is a key investment. Any investment is to improve the product quality, operational efficiency and market competitiveness of the oil mill. GQ-Agri specializes in providing freshly pressed oil filtration machines tailor-made to meet the needs of regional oil mills, farm oil producers, and rural entrepreneurs who value reliability and simplicity.

After visiting many customers, we found that each oil mill has different market operation goals – some press oil in fixed facilities, some provide mobile oil pressing services; some focus on clarity after filtration, and some focus on speed or low cost. Therefore, in order to meet the needs of different customers, we provide a series of edible oil filter machines, each suitable for different production scenarios. I will briefly compare the four main edible oil oil filter machines provided, hoping to help you make a more appropriate purchasing decision.

Oil Filter Machine Comparison Table
Filter Type	Working Principle	Main Advantages	Limitations	Best For
Centrifugal Oil Filter	High-speed spinning separates oil from solid particles by centrifugal force	– Fast filtering speed – No need for filter cloth – Easy to clean	– Higher cost – Requires electricity and balance maintenance	Commercial oil workshops needing fast processing with clear oil
Vacuum Oil Filter	Uses vacuum suction and multi-layer fine filtration to remove impurities	– Very fine filtration – Produces clean, transparent oil – Ideal for edible-grade oil	– Slower speed – Filter elements need replacement	High-quality edible oil producers (peanut, sesame, sunflower oil, etc.)
Plate Oil Filter Press	Oil is forced through filter cloth between metal plates under mechanical pressure	– Durable and effective – Good for large batches – Common and affordable	– Requires manual filter cloth cleaning – Takes more space	Fixed small to medium oil mills with stable production volume
Pneumatic Oil Filter	Compressed air drives oil through filter layers under high pressure	– Energy-efficient – Compact size – Works where power supply is unstable	– Needs air compressor – Not as fine as vacuum filter	Rural areas with poor electricity, mobile oil filtering setups
Edible Oil Refinery Equipment	Multiple-stage fine filtration as part of oil refining process (degumming, bleaching, deodorizing steps)	– Highest oil purity and stability – Upgrades oil to premium market grade – Extends shelf life	– Higher investment – Requires basic technical knowledge – Slower speed	Small edible oil bottling lines, co-ops producing premium packaged cooking oil
