If you're running a screw press oil extraction line, especially with canola seeds, one mistake in pre-treatment can cost you up to 3% lower yield per ton—and maybe even force an unplanned shutdown. This isn’t just theory—it’s what happens when moisture control, temperature, or time aren’t optimized.
Before any crushing or cooking, remove stones, dust, and foreign materials. Even 1–2% impurities can lead to increased wear on rollers and screw presses. For canola, use a magnetic separator followed by a vibrating screen with 1.5 mm mesh. Our data from 12 factories shows that this step alone boosts throughput by 5–7% over six months.
| Parameter | Recommended Range (Canola) | Why It Matters |
|---|---|---|
| Moisture Content | 6–8% | Too dry = poor adhesion during pressing; too wet = clogging risk |
| Temper Time | 15–25 min | Ensures uniform heating—critical for consistent cake quality |
| Cooking Temp | 95–105°C | Optimal for protein denaturation without burning the seed |
Let’s be honest—most operators know these problems but don’t always fix them fast enough:
One plant in India saw their output rise from 1.2 tons/hour to 1.45 tons/hour simply by adjusting the tempering time based on seasonal humidity changes.
