Why the screw press dominates small oil production
Screw presses handle the widest range of oilseeds — peanut, sunflower, soybean, sesame, rapeseed, copra, cottonseed — with continuous feeding and one-person operation. For farmers, market vendors and small processors, it is the lowest-risk entry into oil production: one machine, one power connection, direct sale of oil and cake.
Key parameters to define
- Seed type and its oil content — capacity figures shift by seed.
- Target seed throughput per day and working hours.
- Hot or cold pressing for your market's taste and shelf-life expectations.
- Whether a built-in heating ring and filter are required.
- Residual oil in cake acceptable to your buyers (cake is a second revenue stream).
Typical configuration ranges
| Item | Common options | Indicative range |
|---|---|---|
| Capacity class | Small commercial to workshop scale | 60–850 kg/h seed |
| Heating | Press chamber heating ring | For hot pressing |
| Motor | Single or three phase | 5.5–18.5 kW |
| Residual oil | By seed and press adjustment | 6–8% in cake typical |
Ranges are indicative. Real capacity depends on seed species, pretreatment and pressing temperature.
What a quotation should clarify
| Quotation area | Questions to record |
|---|---|
| Seed basis | Which seed and moisture is the capacity figure measured on? |
| Oil yield | What extraction rate is demonstrated for your seed? |
| Wear parts | Press screw and cage bar life, replacement cost? |
| Electrics | Voltage, phase and starter matched to your supply? |
| Test run | Video of your seed type being pressed before shipment? |
