What is a commercial oil expeller?
An oil expeller presses oil out of oilseeds. Seed is cleaned first, then fed from a hopper into the machine, often after cooking in a steam-jacketed kettle where a stirrer stops it burning. A motor turns a worm, a screw shaft, inside a barrel built from slotted cage bars. The seed is squeezed against a cone at the outlet. Oil drains through the slots, and the pressed cake leaves at the end, where the cone gap sets how thick the cake is. Many mills press the cake a second time to recover more oil. The oil is settled and filtered, and the cake is sold as cattle feed. Common seeds are groundnut, mustard, rapeseed, sesame, linseed and castor.
This page covers commercial and industrial oil expellers and oil mill machinery; small machines meant for home use are not covered.
How diipl verifies oil expeller manufacturers
diipl checks every oil expeller manufacturer before a buyer meets them. Every seller is GSTIN verified and capacity audited. IEC and the certifications your product and market need (ISO, CE, REACH, BIS) are confirmed before any meeting; Certificate of Origin and EIC inspection are arranged per shipment where required.
For oil expellers, the capacity audit also covers:
- A metered no-load run of the expeller, with the maker's team watching for vibration, knocking, hot bearings and slipping belts
- A loaded run on the buyer's own seed at the declared hourly feed, after the cake outlet temperature has settled, with oil and cake collected and weighed
- Cake and oil samples drawn during the loaded run and kept for laboratory checks of the oil left in the cake and the acid value of the oil, set against the figures the maker has declared
- Records for worm, collar and cage bar material and hardness, plus a look at the finish of the barrel and the fit of the worm in it
- The kettle, stirrer, heating fittings and safety valve, the cone adjustment turning smoothly, and guards, lubrication points and machine marking in place
We match your requirement to a manufacturer that has passed these checks and arrange a direct meeting.
Types of oil expellers we cover
Indian oil expeller manufacturers on the diipl bench build these commercial and industrial types.
| Type | Typical buyers |
|---|---|
| Single-barrel expeller with cooking kettle | Mustard, groundnut, rapeseed and linseed oil mills |
| Cold press expeller (no seed pre-heating) | Mills and brands selling oil pressed without cooking the seed |
| Rotary ghani (motor-driven) | Small mustard, rapeseed, groundnut and coconut oil units |
| Complete expeller line with cleaner and filter press | New oil mills, farmer groups and small processors |
Single-barrel expeller with cooking kettle
The usual mill machine. Seed is cooked in a steam-jacketed kettle, then pressed in one or two stages through a single barrel. An electric motor turns the worm through belts or gears, and the cone at the outlet sets cake thickness. The BIS specification for single-barrel expellers recommends nominal capacities of 50, 100, 200 and 400 kilograms per hour. Choose it for groundnut, mustard or rapeseed when you want little oil left in the cake.
Cold press expeller (no seed pre-heating)
The press is the same kind of screw expeller, but it takes seed at room temperature with no cooking step. One maker says the oil normally does not exceed 50 degrees Celsius, and that the technology is simple, uses little energy and needs little floor space. Expect more oil left in the cake than with a cooked first stage, so makers also offer a two-level version for higher yield. Choose it when your oil is sold on gentle pressing.
Rotary ghani (motor-driven)
A ghani crushes seed with a pestle turning in a mortar. A rotary is a mechanised ghani built into a factory, and the Khadi and Village Industries Commission developed several electric-powered designs, including a rotating barrel power ghani. A ghani presses at much lower pressure than a screw press, and its cake keeps about 15 percent fat, roughly twice that of screw-press cake. Choose it for small output where lower recovery is acceptable.
Complete expeller line with cleaner and filter press
Beyond the press itself, a line adds a shaker screen with blower to clean the seed, the cooking kettle, a frame-type filter press with pump, oil storage tanks and, where the kettle runs on steam, a small boiler. A government mustard oil project profile lists these items around a baby expeller rated at 110 kilograms per hour. Choose a line when you are starting a new mill and want one maker to answer for the whole flow.
What to specify when buying an oil expeller
A clear oil expeller specification gets you comparable offers and a faster meeting. Share these points with diipl and we match them to the right manufacturer.
| What to specify | Why it matters |
|---|---|
| Seed type, moisture and foreign matter | State each seed you will press. The BIS test code prefers groundnut and mustard as trial seeds and counts sand, gravel, stones, iron chips and chaff as foreign matter to be measured before a trial. |
| Rated capacity per hour on your seed | Capacity changes with the seed. The BIS single-barrel specification has the maker declare nominal capacity per hour and recommends 50, 100, 200 and 400 kilograms per hour. Ask for the figure on your own seed. |
| Oil left in the cake at the rated feed | The BIS test code accepts a rated feed only where the cake holds not more than 8 percent oil, with the oil's acid value unchanged from its original value. Ask for the maker's figure at the feed rate you plan. |
| Cooking kettle and heating details | Say whether seed is cooked first. The BIS specification lists kettle heating area, steam pressure and steam use, and wants the cooking time and temperature declared. Also ask the kettle size and how the seed is stirred. |
| Steam source and boiler, if the kettle uses steam | Ask boiler size, fuel and whether a safety valve is fitted. A government mustard oil profile lists a small boiler alongside the expeller and advises avoiding too much steam while softening seed in the kettles. |
| Motor power, drive type and worm speed | Ask rated motor power, whether the drive is belt or gears, and worm speed. The BIS specification expects belt tightening and guards on belt drives, and a power rating marked on the machine. |
| Worm, collar and cage bar material and hardness | These parts wear first. The BIS specification asks for cage bars case hardened to 45 to 50 HRC, worms and collars to 50 to 60 HRC, with hardening at least 1 mm deep. Ask for test records. |
| Cone (choke) adjustment | A government innovation catalogue records one innovator's view that conventional expellers cannot adjust cake thickness while running, and that keeping cake oil near 6 to 7 percent is hard. Ask how the cone is adjusted under load. |
| Power use at rated load | The BIS specification asks that a two-stage run on groundnut kernels give at least 15 kilograms of seed per kilowatt-hour, and that no-load power be not more than 15 percent of rated power. Ask for the maker's readings. |
| Seed cleaning ahead of the press | Ask what cleaning is included ahead of the press and how often screens are changed. A government mustard oil profile lists a shaker screen with blower, and its process cleans the seed of dust and foreign matter before steaming. |
| Oil settling, filtering and storage | Ask what takes the solids out of the pressed oil. A government mustard oil profile lists a frame-type filter press with plunger pump and filter cloth, plus oil storage tanks. Ask plate size, filter area and tank capacity. |
| Guards, marking and operator manual | The BIS specification asks for transmission guards, a feed regulating system, easy-to-reach lubrication points, an operator's manual, and marking that shows maker, model, serial number, nominal capacity and power rating. |
| Foundation and floor space | A government innovation catalogue says conventional belt-driven expellers need a concrete foundation to absorb vibration and, in the 6 to 10 tonnes per day class, about 9.2 m by 3.8 m of floor. Ask for the foundation drawing. |
| Wear parts and spares | Worms, collars and cage bars wear with use. The BIS test code checks whether parts needing frequent replacement can be changed easily. Ask for a spares list and the maker's supply time for each part. |

HSN code and ITC-HS code for oil expellers
Oil expellers are classified under ITC-HS 84792010 (oil-seed crushing or grinding machinery including purifying tanks), within HS subheading 847920 (machinery; for the extraction or preparation of animal or fixed vegetable or microbial fats or oils). The 6-digit subheading is the same in every country that uses the Harmonized System; the 8-digit ITC-HS line is the one India files.
In India the GST HSN code and the export ITC-HS code come from the same nomenclature. A GST invoice needs only the first 4 or 6 digits, depending on your turnover; the export shipping bill carries the full 8-digit ITC-HS line. The classification is shown here; the applicable GST rate is not. Official source.

Buying an oil expeller in India
- Ask for a GST invoice that describes the expeller, kettle and drive fitted, and for a written schedule for delivery, erection and a trial run on your own seed.
- Plan the floor before the machine arrives: belt-driven expellers that crush several tonnes of seed a day need a concrete foundation to take up vibration, plus room to move seed, cake and drums around the machine.
- Match the power supply to the motor list and fit a voltage stabiliser, as the BIS trial for expellers does. If the kettle uses steam, plan the boiler, fuel store and safety valve too.
- Settle who supplies the seed cleaner, filter press and oil tanks, and list them in the same order document as the press.
- Train your operators on feed rate, cone setting and kettle temperature, and keep a log of cake oil checks. Get a spares list for worms, collars, cage bars, bearings and belts, with supply times.
- Check which FSSAI registration or licence your oil mill needs before you start, since FSSAI guidance lists oil expeller units under vegetable oil processing, and ask your State Pollution Control Board whether consent is needed.
Buying from Indian oil expeller exporters
- Agree the Incoterms in writing, including who pays for unloading and erection, and ask for a packing list that names each part, such as the worm shaft, barrel halves, gears and kettle.
- A Certificate of Origin may be needed at your customs office or under a trade agreement; ask the maker to issue it with the shipping papers.
- Match the electrical supply in words: voltage, frequency and phase for the motor and panel, and say how the kettle is heated.
- For the European Union, ask for the declaration of conformity and the technical file. Oil expellers are not named in the higher-risk list of Annex I, so ask which conformity route the maker follows, and ask for food-contact declarations for the hopper, worm, barrel and oil channel.
- Ask for a written trial report on seed like yours, showing feed rate, power drawn, oil left in the cake and the oil's acid value, ideally witnessed before shipment.
- In North America, check belt, pulley, gear and shaft guards against local workplace rules, and order a spares kit and remote commissioning support with the machine.
Standards and certifications for oil expellers
Oil Expellers for each market must meet that market's rules. diipl confirms the certifications your market needs before any meeting. Each requirement below links to its official source.
| Indian standard or rule | What it covers | Official source |
|---|---|---|
| IS 5224:1993Oilseeds Milling Machinery - Oil Expellers Single Barrel - Specification (Second Revision) | Sets material, performance and other requirements for single barrel oil expellers, including hardness of wearing parts, power use, guards and marking. Ask each maker whether its machine is built and tested to it. | View source |
| IS 5223:1993Oilseeds Milling Machinery - Oil Expellers - Test Code (First Revision) | Method for testing an expeller: a no-load run, a loaded run with oil and cake sampling, rated capacity and a long run. It can serve as the basis for a factory trial. | View source |

Oil Expeller: frequently asked questions
Who makes oil expellers in India?
Makers are not named on diipl pages. You send diipl the seed you press, the feed rate you need and whether you want a cooked or an unheated press. diipl then finds a maker whose GSTIN is verified and whose works have been audited, and introduces you in a meeting. For an expeller the audit means a metered no-load run and a loaded run on real seed, with oil and cake sampled as the BIS test code describes.
What capacity and settings should an oil expeller maker state?
Name each seed, the feed rate per hour and whether the seed is cooked. Ask for motor power, worm speed, cone setting and the oil left in the cake at that feed. The BIS specification has the maker declare nominal capacity per hour and mark it on the machine, and recommends 50, 100, 200 and 400 kilograms per hour. Always ask for hourly capacity on your own seed.
Which standards apply to oil expellers made in India?
Among the BIS standards for the machine are IS 5224 for the single barrel expeller specification, IS 5223 for the test code and IS 4596 for terms. The specification lets a maker mark the machine with the Standard Mark, so ask for proof. The oil itself falls under FSSAI rules, which define raw edible oils as oils obtained by expelling or pressing.
What is the HSN code for oil expellers?
Oil Expellers are classified under ITC-HS 84792010 (oil-seed crushing or grinding machinery including purifying tanks), within HS subheading 847920. The export shipping bill carries this full 8-digit line; a GST invoice needs only its first 4 or 6 digits, depending on your turnover. Confirm the 8-digit line against your exact machine before you file.
Can Indian manufacturers export oil expellers?
Yes. The maker needs an Importer Exporter Code, which the DGFT handbook calls compulsory for exports apart from listed exemptions. Importers in the European Union will ask for conformity papers and food-contact declarations for parts that touch seed and oil. Plants in North America expect belts, pulleys and gears to be guarded. Send a spares kit with the machine.
Which industries buy oil expellers?
Oil mills that press mustard, rapeseed, groundnut, sesame and sunflower seed buy them. India's national oilseeds mission names those crops and backs farmer producer organisations, cooperatives and industry in setting up or upgrading post-harvest units, so new community mills may buy too. Castor seed crushers and kachi ghani mustard oil units also use expellers.
I make oil expellers. How do I find verified buyers?
diipl studies which oilseed belts and mill types need your capacity class, reaches them through its outreach channels, and checks that each prospect has a seed supply, a person who can sign, funds and a date. A meeting is then set with you, and your company name stays off the page. Expeller buyers usually want a trial on their own seed, so keep recorded trial figures ready.
How much oil stays in the cake, and can it be lowered?
The BIS test code accepts a rated feed only where the cake holds not more than 8 percent oil and the oil's acid value is unchanged from the seed's. Capacity is defined for a two-stage run, where the cake is pressed again to recover more oil. Ask the maker for cake oil readings at your feed rate, taken on your own seed.
How is a cold press oil machine different from a cooked-seed expeller?
A cold press machine takes seed at room temperature with no cooking step. The Codex standard for named vegetable oils describes cold pressed oils as obtained by mechanical procedures without the application of heat. The trade-off is more oil in the cake: an insurance industry reference gives 15 to 25 percent for pressing at around 40 degrees Celsius, against 5 to 10 percent for hot final pressing.
Can oil from my expeller be sold as kachi ghani?
FSSAI's mustard oil standard says the oil may be labelled Kachi Ghani or Cold Pressed if the natural allyl isothiocyanate content is not less than 0.20 percent by weight. So the standard ties the label to a lab result for your oil, not to the machine name. Test your oil before you print the label, and check the current FSSAI text.
What does a 6 bolt or 9 bolt oil expeller mean?
Some makers and buyers quote expellers by chamber bolt count. A government mustard oil profile, for example, lists a nine bolt baby expeller at 110 kilograms per hour. The bolts clamp the two halves of the barrel together. The BIS specification states capacity in kilograms per hour instead, so always ask for hourly feed on your seed.
