Calculate Your Expected Oil Yield
Pick your seed and pressing method, enter the raw material quantity — get an honest range, not a fantasy number. Ranges come from published agronomy data and what we see on our own test floor.
How the estimate works
Oil out = quantity × seed oil content × press recovery × moisture factor. The result is strongly affected by seed condition, preparation, press setup and wear. Test residual oil in the press cake rather than assuming a universal recovery value.
| Seed | Typical oil content |
|---|---|
| Peanut / Groundnut (shelled) | 44–50% |
| Sesame | 48–55% |
| Sunflower (oilseed type) | 38–48% |
| Soybean | 17–20% |
| Rapeseed / Canola | 38–44% |
| Mustard | 33–40% |
| Cottonseed (delinted) | 15–20% |
| Copra (dried coconut) | 60–68% |

Oil yield methodology and test conditions
The calculator is a planning model, not a production guarantee. Its useful output is a range that can be replaced by verified data from your own seed sample and trial run.
| Input | What to record | Why it matters |
|---|---|---|
| Gross seed mass | Weighed batch entering preparation | Defines the material-balance starting point. |
| Moisture and impurities | Test method, sample date and basis | Separates water and foreign matter from comparable seed mass. |
| Oil content | Supplier certificate or laboratory test | Defines the oil theoretically present in the seed. |
| Process recovery | Trial-run oil output and cake residual-oil test | Replaces a planning assumption with measured recovery. |
| Outlet balance | Crude oil, cake, settled solids and identifiable losses | Checks whether the result is physically consistent. |
Calculation logic
Expected crude oil = corrected seed mass × tested oil content × measured or assumed recovery. Keep every input on the same wet or dry basis, and state whether settled solids are included in the oil weight.
Frequently Asked Questions
Because real yield depends on seed variety, moisture, roasting and press condition. Anyone quoting a single exact percentage before testing your seed is guessing. The range covers published agronomy data plus normal press recovery.
The suitable moisture range depends on the oilseed, preparation route and press. Use a documented test method and the approved process guidance, then confirm the target with a small controlled trial.
Check the feedstock test basis, cleaning and conditioning, operating settings, restriction or blockage, component wear and the way oil and cake were weighed. Change one variable at a time and repeat a controlled test.
A second pass may be evaluated, but first test residual oil in the cake and compare the extra recovery with throughput, energy and quality effects. Confirm the route for the selected press and feedstock.
