For small to medium oil mills striving for higher oil output, the ZY24 (202-3) spiral screw press offers precision control and operational finesse that can transform your production efficiency. This guide walks you through the critical technology and proven techniques—from raw material preparation to the fine-tuning of machine parameters—that significantly boost oil yield for common oilseeds like rapeseed, peanut, and sunflower.
Before the oil extraction process begins, controlling the moisture content and particle size of your feedstock is essential to minimize oil retention and maximize yield.
| Oilseed Type | Optimal Moisture Content (%) | Ideal Crush Size (mm) |
|---|---|---|
| Rapeseed | 7-9% | 1.2-1.5 |
| Peanut | 6-8% | 1.0-1.3 |
| Sunflower Seed | 8-10% | 1.3-1.6 |
Maintaining raw material moisture within these ranges improves cell rupture during pressing and reduces oil trapped in pomace, increasing yield by up to 8% compared to unregulated inputs.
The heart of ZY24 (202-3) performance lies in its robust control over pressing chamber pressure and temperature, which critically affects oil release and quality.
Implementing a real-time monitoring system for these variables ensures steady-state operation. Field data indicates that mills adopting these strategies improved oil yields by 5-10% within 3 months of adjustment.
The ZY24 (202-3) allows fine-tuning of critical mechanical parameters to accommodate different seed characteristics, maximizing efficiency.
| Parameter | Rapeseed | Peanut | Sunflower Seed |
|---|---|---|---|
| Screw Rotation Speed (rpm) | 18-22 | 15-20 | 20-24 |
| Barrel Clearance (mm) | 0.5-0.7 | 0.7-1.0 | 0.6-0.8 |
| Pressing Zone Distribution | Balanced, with longer compression zone | Short compression zone, longer pre-pressing | Standard distribution |
These adjustments help balance throughput with extraction efficiency. Over-tight clearances can cause mechanical stress and oil loss due to overheating, while oversize gaps reduce pressing force and yield.
Industry veterans emphasize that mastering the press also means steering clear of frequent errors that undercut output:
“Consistent sample testing and process logging are your best tools. Without data-driven adjustments, even minor deviations in moisture or machine speed can cut your oil yield by 3-5%.” – Senior Mechanical Engineer, ZY Machinery
Preventative maintenance schedules combined with standardized SOPs for feeding, temperature control and periodic training yield measurable improvements.
Here’s a practical workflow you can adopt immediately to unlock higher extraction rates:
These steps leverage the ZY24 (202-3) design for continuous adaptation, helping your oil mill reliably push output by up to 15% within 90 days of systematic tweaks.
