Application Tutorial
The ZY24 (202-3) continuous screw oil press offers both one-stage solvent extraction and two-stage pressing modes—ideal for small to medium-sized oil mills handling diverse feedstocks like rapeseed, peanuts, sunflower seeds, and cottonseed. This guide breaks down when to use each mode based on oil content, processing efficiency, and real-world outturns (e.g., peanut oil yield ≥45%). Learn how switching between modes boosts throughput, reduces equipment footprint, and increases profitability—without buying multiple machines. Whether you're scaling production or expanding your product line, this insight helps optimize your process and stay competitive globally.

One-Stage vs. Two-Stage Pressing: How ZY24 (202-3) Screw Oil Press Adapts to Your Raw Material Needs

In the competitive world of small-to-medium oilseed processing plants, flexibility and efficiency are not just advantages—they’re survival tools. Many operators struggle with handling multiple oil types like rapeseed, peanuts, sunflower seeds, or cottonseed using fixed-process equipment. That’s where the ZY24 (202-3) continuous screw oil press shines—it supports both one-stage and two-stage pressing modes, allowing you to optimize output based on feedstock and market demands.

Key Performance Metrics Across Oils

Oil Type Typical Yield (%) Recommended Mode
Peanuts ≥45% Two-stage
Rapeseed ≥38% One-stage
Sunflower Seeds ≥42% Two-stage
Cottonseed ≥35% One-stage

Why It Matters: The Real Difference Between Modes

One-stage pressing is ideal for high-oil-content seeds like rapeseed or cottonseed—fast, simple, and energy-efficient. It typically achieves 35–40% yield with minimal setup time and maintenance. For peanut processing, however, two-stage pressing delivers superior results: first press removes about 60% of oil, then a second pass extracts an additional 15–20%, boosting total yield to over 45%.

This dual-mode capability means one machine replaces three single-function presses—saving floor space by up to 40% and reducing capital investment by 25–30%. In practice, this translates into faster ROI and easier scalability when switching between seasonal crops.

Real Impact: A Case Study from Southeast Asia

“We switched from a single-mode press to the ZY24 (202-3) last year. By adjusting our mode for each oil type—especially peanuts—we increased annual revenue by 15%. More importantly, we now handle four different oils without buying new machines.”
— Mr. Lin, Operations Manager, Vietnam Oil Co.

Whether you're aiming to reduce operational costs, expand your product line, or improve consistency across batches, the ZY24 (202-3) offers a scalable solution rooted in real-world performance data—not just theory.

Ready to Upgrade Your Process?

If you're managing a multi-oil facility or planning to diversify raw materials, understanding how to match pressing mode with feedstock is critical. This isn’t just about outperforming competitors—it’s about future-proofing your plant.
