For small to mid-sized oil extraction plants, pre-treatment is the unsung hero behind consistent output and machine longevity. While many operators focus on the pressing stage, it’s the careful control of moisture and temperature during cleaning, crushing, and steaming that determines whether your ZY24 (202-3) continuous screw press runs smoothly—or breaks down.
Each oilseed—peanut, canola, and cottonseed—has unique physical and chemical properties that demand tailored pre-treatment protocols:
| Oilseed Type | Optimal Moisture (%) | Steaming Temp (°C) | Impact on Output | Risk of Equipment Wear |
|---|---|---|---|---|
| Peanut | 7–9% | 95–105°C | +2.5% to +3.2% oil yield | Low (if properly dried) |
| Canola | 6–8% | 85–95°C | +1.8% to +2.5% oil yield | Medium (dust accumulation risk) |
| Cottonseed | 8–10% | 90–100°C | +3.0% to +4.0% oil yield | High (if improperly handled) |
A real-world case from a Thai processor shows how adjusting peanut particle size—from coarse to fine (≤3mm)—boosted outturn by 3.1% while reducing mechanical stress on the ZY24 screw press. Similarly, a Turkish facility avoided frequent blockages after switching from 15-minute steaming to 12 minutes at 90°C for canola seeds.
Over-steaming peanuts leads to protein coagulation and poor cake quality—often mistaken for “bad equipment.” Meanwhile, under-heating cottonseed leaves gossypol active, risking both product safety and regulatory non-compliance. These errors aren’t just operational—they’re costly.
That’s why we developed a standardized checklist used by over 30 facilities worldwide. It includes daily moisture checks, pre-steam calibration logs, and visual inspection points for each seed type. When followed consistently, this process reduces unplanned downtime by up to 40%.
If you're running a ZY24 (202-3) spiral oil press and want to maximize efficiency without sacrificing equipment life, you need more than intuition—you need data-driven steps.
We’ve compiled our most effective methods into an actionable PDF guide—including sample SOPs, a downloadable moisture/temperature log sheet, and a troubleshooting flowchart based on actual plant feedback. Whether you're optimizing for higher yields or minimizing wear, this toolkit gives you a clear path forward.
