As a small to mid-sized oil mill operator, you’re likely facing a critical decision: Should your plant adopt secondary pressing or go with one-step solvent extraction when processing rapeseed, peanuts, or cottonseed? This isn’t just a technical question—it’s a strategic one that impacts your production costs, residual oil levels, and long-term profitability.
Let’s start with hard numbers. In real-world operations:
| Process | Avg. Residual Oil (%) | Energy Cost per Ton (USD) | Equipment Investment (USD) |
|---|---|---|---|
| Secondary Pressing | 6–8% | $75–$110 | $15,000–$30,000 |
| Solvent Extraction | 1–2% | $120–$180 | $50,000–$120,000+ |
These figures aren’t hypothetical—they come from over 40 operational case studies across Southeast Asia, Eastern Europe, and Latin America. The key takeaway? Secondary pressing doesn’t mean lower yield—it means smarter use of capital and energy.
If you choose secondary pressing, the ZY24 continuous screw press becomes the backbone of your operation—not just a machine, but a productivity multiplier. Why?
In short: it’s not just about pressing—it’s about making your entire line more efficient, predictable, and profitable.
Case Study 1: Peanut Mill in Indonesia
After switching from solvent extraction to secondary pressing using ZY24, their residual oil dropped from 1.5% to 6.8%, while energy consumption fell by 38%. The payback period? Just 8 months.
Case Study 2: Cottonseed Processor in Kazakhstan
They initially tried solvent extraction but found the meal had too much residual oil for animal feed—meaning lower market value. Switching to ZY24-based secondary pressing improved feed quality and allowed them to sell directly to livestock farms instead of processors.
These aren’t outliers—they’re replicable outcomes if you understand how to match process to raw material and scale.
