How to Optimize Your Spiral Oil Press for Different Raw Materials

Running a small-to-medium oil mill? You’re likely facing one recurring challenge: inconsistent extraction rates, rising energy costs, and machine downtime — especially when switching between crops like rapeseed, peanuts, or sunflower seeds.

That’s where the ZY24 (202–3) Continuous Screw Oil Press comes in. Designed with adaptability at its core, this unit isn’t just another piece of equipment — it's a precision tool that can be tuned for each oilseed type, boosting yield by up to 12% while reducing power consumption by 8–15% compared to standard setups.

Why This Matters for Your Operation

According to a 2023 study by the International Oilseed Processing Association, over 68% of small-scale producers report suboptimal performance due to improper parameter settings — not faulty machines. The key lies in understanding how raw material characteristics influence pressing efficiency.

“The real difference between good and great oil extraction isn’t the press itself — it’s how well you match it to the feedstock.”

Key Optimization Levers: From Pre-Treatment to Parameters

To unlock consistent high yields across different oils, focus on three pillars:

• Moisture Control: For peanuts, aim for 7–9%; for rapeseed, keep it at 5–7%. Too much moisture causes slippage; too little leads to poor oil release.
• Crushing Particle Size: Target 0.8–1.2 mm for most seeds. Larger particles reduce contact surface area; smaller ones increase friction and wear.
• Pressure & Temperature Management: Adjust barrel temperature based on seed type — typically 70–85°C for peanuts, 90–100°C for sunflower seeds.

Avoid These Common Mistakes

One client in Egypt lost 14% yield in two months simply because they used the same settings for both sesame and soybeans — a clear case of “one-size-fits-all” failure. Other frequent errors include:

• Ignoring pre-heating steps for cold-pressed oils
• Using old or worn-out screw blades without replacement
• Overloading the feed hopper — leading to uneven pressure distribution

These aren’t just technical oversights — they directly impact your bottom line.

If you're serious about improving output consistency and lowering operating costs, don't guess — optimize.
