When hydraulic beats screw
Sesame oil for Asian and Middle East markets, walnut and almond oil for health-food buyers, cocoa butter for cosmetics — these products sell on aroma and low-temperature processing. A hydraulic press batch-presses seed cake under high pressure without the friction heat of a screw press, keeping the oil's character intact.
Key parameters to define
- Seed or kernel type and its market grade requirements.
- Batch size and acceptable cycle time per batch.
- Roasting before pressing: required for sesame aroma, avoided for raw claims.
- Target oil temperature during pressing for cold-press labeling.
- Daily oil output target — hydraulic presses run lower throughput than screw presses.
Typical configuration ranges
| Item | Common options | Indicative range |
|---|---|---|
| Batch load | Chamber size by model | 6–25 kg per batch |
| Cycle time | Load, press, discharge | 8–15 minutes |
| Pressure | Hydraulic system rating | Up to 60 MPa class |
| Throughput | Batches per hour | 30–150 kg/h seed |
Ranges are indicative. Premium oil pricing usually offsets the lower throughput.
What a quotation should clarify
| Quotation area | Questions to record |
|---|---|
| Oil quality | What pressing temperature is maintained on your seed? |
| Yield | Residual oil in cake for sesame/walnut specifically? |
| Cycle | Real batch cycle time including loading and discharge? |
| Hydraulics | Pump brand, seal life and spare seal pricing? |
| Test run | Video of your seed pressed, with yield measured? |
