Description

Looking for an oil filter machine manufacturer and supplier in Delhi, India? Our oil filter machine is an essential companion to any oil expeller operation, providing the filtration and clarification needed to transform freshly pressed crude oil into clean, clear, market-ready oil. Whether you run a small cold-press unit or a large-scale oil mill, the quality of your filtration directly determines how your oil looks, tastes, and shelf-stable it becomes. Unfiltered oil contains fine cake particles, gums, and other suspended matter that cause rapid spoilage, off-flavours, and an unappealing cloudy appearance. Our oil filter machine removes these contaminants efficiently, giving you a finished product that meets consumer expectations and food safety standards. Every unit is built at our Nangloi, Delhi factory with durable components and a practical design for daily use in oil production environments.

What is an oil filter machine? An oil filter machine is a mechanical filtration system that removes solid particles, fine press cake residue, gums, and other impurities from freshly extracted crude oil. It works by passing the oil through one or more filter media, such as filter cloth, filter paper, or a fine mesh screen, under pressure or vacuum, which forces the clean oil through while trapping the contaminants on the filter surface. The result is a clear, sediment-free oil that looks attractive in the bottle, has a longer shelf life, and is free from the gritty texture and off-flavours that unfiltered oil carries. In the Indian oil production context, filtration is not optional but a necessary step between the expeller and the packaging stage.

Key Features and Build Quality. Our oil filter machine uses a plate-and-frame or leaf filter design, depending on the model, constructed entirely from food-grade mild steel or AISI 304 stainless steel for the oil-contact components. The filter press consists of a series of plates held together in a frame, with filter cloth sandwiched between each pair of plates. Crude oil is pumped into the press under pressure, and the oil passes through the filter cloth while the solid particles are trapped on the cloth surface. When the filter becomes loaded with particles and the flow rate drops, the press is opened, the used filter cloths are removed and cleaned or replaced, and the press is reassembled for the next cycle. Our larger models use an automatic backwash or self-cleaning mechanism that reverses the oil flow periodically to dislodge trapped particles from the filter surface, extending the time between manual cleanings. A robust oil pump, included with the machine, provides the pressure needed to push the oil through the filter media, and the pump is sized to handle the viscosity range of commonly pressed oils at ambient temperature.

How does the oil filter machine work? The process begins after the oil exits the expeller and has settled briefly in a crude oil tank where the heaviest particles sink to the bottom. The operator draws oil from the middle of the tank, leaving the heaviest sediment behind, and feeds it into the filter machine. The pump pushes the oil into the filter press at a pressure of 1 to 3 bar, depending on the oil viscosity and filter condition. The oil passes through the filter cloth on each plate, and the clean oil exits from the other side into a collection manifold that directs it into a clean storage tank. Solid particles accumulate on the filter cloth, gradually forming a cake layer that itself acts as an additional filter medium, improving filtration fineness as the cake builds. When the pressure differential across the press reaches a threshold indicating the filter is loaded, the operator shuts off the pump, drains the remaining crude oil from the press, opens the plates, and scrapes or removes the filter cake from the cloths. The cloths are washed, dried, and reinstalled, or replaced if they are worn. The entire cycle from loading to cleaning takes about 30 minutes to an hour depending on the volume of oil processed.

Technical Specifications. Our standard oil filter machine has a filtration capacity of 20 to 50 litres per hour, suitable for small to medium oil mill operations. A larger model rated at 100 to 200 litres per hour is available for high-volume production. The filter press contains 10 to 20 plates in the standard model, with each plate measuring 300 mm by 300 mm, providing a total filtration area of approximately 1.5 to 3 square metres. The oil pump is a positive displacement gear pump with a 1 HP motor, running on 220V single-phase or 415V three-phase power. The maximum working pressure is 4 bar. The machine dimensions are approximately 800 mm by 400 mm by 600 mm for the filter press unit, plus the pump assembly which sits alongside. Total weight is about 60 kilograms. Filter cloths are supplied in multiple sets and are washable and reusable for several cycles before replacement is needed.

Applications and Industries. This machine is used in every type of oil production operation from home-based cold-press units to large commercial oil mills. It is essential for edible oil producers who need clear, attractive oil for retail packaging, for cold-pressed oil brands where the visual clarity of the oil is a key quality indicator, for coconut oil producers who need to remove fine copra particles, for mustard oil mills where filtered oil commands a higher price than crude oil, for industrial oil producers who supply non-edible oils to chemical and manufacturing industries, and for laboratory and research facilities that need clean oil samples for testing and analysis. Government food testing labs and quality certification agencies also use small oil filter units to prepare samples.

Benefits of Choosing Our Oil Filter Machine. The immediate benefit is a dramatic improvement in oil appearance. Crude oil straight from the expeller is cloudy and contains visible particles. After filtration, it becomes clear and bright, which is what consumers expect and what retail packaging requires. Filtered oil has a significantly longer shelf life because the suspended particles that cause oxidation and rancidity are removed. The taste and aroma improve because fine press cake particles that carry a bitter or burnt flavour are eliminated. The filter cake that accumulates on the cloth is a saleable by-product that can be sold as animal feed or used in composting. The machine is simple to operate and does not require specialised training, which means any worker in your oil mill can run it after a brief instruction session.

Maintenance and Care. Inspect the filter cloths after every use and wash them thoroughly with warm water and a mild detergent to remove oil and particle buildup. Replace cloths when they become stained, torn, or when fine particles begin to pass through despite washing. Check the pump seals monthly for leaks and replace the seals if any seepage is noticed. Lubricate the pump bearings every 200 hours. Clean the oil collection manifold and pipework weekly to prevent residue buildup. Inspect the plate alignment periodically and tighten the press closing mechanism if any loosening is detected. Keep spare filter cloths in stock so you are never delayed waiting for cloths to dry after washing.

Frequently Asked Questions. What is the price of an oil filter machine? Pricing depends on the filtration capacity and the number of plates in the press. Contact us for a current quote. How often do I need to clean the filter? This depends on the volume and cleanliness of your crude oil. Typically every 30 minutes to two hours of continuous operation. Can this machine filter any type of oil? Yes, it works for all commonly pressed edible and non-edible oils including groundnut, sesame, mustard, coconut, sunflower, castor, and neem oil. Is a separate pump included? Yes, our standard package includes the pump and motor assembly. How fine is the filtration? Our standard filter cloth removes particles down to approximately 5 to 10 microns, which produces a clear oil suitable for retail sale.
