Oil expeller machines
An oil expeller is the machine that does the actual work of a crushing plant: it takes conditioned seed and separates it into oil and cake, mechanically, with no solvent. Everything else in a mill exists to feed it properly or to clean up what comes out.
Technical data
The range at a glance
Figures as published on each machine’s own page. Capacity varies with seed, moisture and conditioning.
| Model | Crushing capacity | Motor power | Oil left in meal |
|---|---|---|---|
| Optiflow 30 | Sized on request | Sized on request | Sized on request |
| Optiflow 40 | 10–11 TPD final press · 13–14 TPD pre-press | 30 kW × 960 rpm | 6–7% |
| Optiflow 50 | 11–12 TPD final press · 14–15 TPD pre-press | 50 HP × 960 rpm | 6–7% |
What a double-chamber press does differently
Our Optiflow 30, 40 and 50 expellers are double-chamber machines. The second chamber runs a tighter flight pitch than the first, so the cake is compressed twice on its way to the choke rather than once. That is where the low residual oil comes from: 6–7% left in the meal on a correctly conditioned seed, which is the figure we publish on the Optiflow 40 and 50 pages.
Cake thickness, and therefore pressure, is set with the cone choke at the discharge end. It is the operator’s main adjustment and the one that trades throughput against how much oil stays in the cake.
Final press or pre-press
The same machine does two jobs. On a final press it takes the oil down as far as a mechanical press economically can, and the cake is sold as feed. On a pre-press it runs a lighter duty ahead of solvent extraction, so the same machine passes more seed per day and hands on a cake the extractor finishes.
Which one you need is decided by the seed, not by preference. Above roughly 20–25% oil content a single pass pays. Below it — soybean at 19%, cottonseed at 18% — the press exists to take the easy oil and feed an extraction plant.

Questions buyers ask
Before you enquire
- What capacity oil expeller do I need?
- Size it on the seed you will crush per day, not on the oil you want out. An Optiflow 40 handles 10–11 tonnes per day on final press, an Optiflow 50 handles 11–12. Past about 12 TPD on final press you are buying a second press rather than a larger one, and we will tell you so.
- How much oil is left in the cake?
- We publish 6–7% for the Optiflow 40 and 50 on a correctly conditioned seed. Seed quality, moisture and cooking all move that figure, which is why we supply the cooker alongside the press rather than leaving conditioning to chance.
- Which seeds can the expeller handle?
- Mustard, groundnut, soybean, sunflower, canola, sesame and cottonseed among others. The press is the same machine; what changes from crop to crop is the preparation in front of it and whether the duty is final press or pre-press.
- What is the price of an oil expeller machine?
- It depends on the model, the capacity you need, and what goes with it: cooker, crammer feeder, filter press and conveyors. We do not print a list price because two buyers rarely need the same set. Send us your seed and tonnage on WhatsApp and we will quote for that.
- Do you make complete oil mill plants as well as expellers?
- Yes. We build turnkey lines from seed cleaning and cooking through pressing, filtration and meal bagging, and the process line for each seed shows every machine in order.
- Where are your oil expellers made?
- In our own works in Ludhiana, Punjab, where the spare parts are made and hard-faced as well.
- Do you supply wear parts for other brands?
- Yes. Worms, cage bars, cone rings and cone points are hard-faced in our own works and made for all major OEM expellers, not only ours.
