Are you searching for a versatile oil press machine capable of processing a variety of oilseeds, such as sunflower seeds, peanuts, soybeans, and rapeseed? The YZS Series Screw Oil Press combines advanced mechanical pressing technology with a robust and durable design to deliver stable and efficient oil extraction for both small-scale artisanal oil mills and industrial oil processing plants. Whether you need a small oil press for home use or a high-capacity sunflower oil press for commercial edible oil production, our machines are carefully designed to maximize output while minimizing operating costs.
Why Choose Our YZS Series Oil Press?
Our seed oil press systems are trusted by customers across Asia, Africa, Europe, and the Americas. Here’s what makes them the preferred choice for edible oil extraction:
✅ High Oil Yield – The helical screw design and adjustable pressing chamber create high pressure that extracts up to 92–96% of available oil.
✅ Energy Efficient – Equipped with high-efficiency motors and optimized gearboxes, our oil press machine consumes up to 40% less electricity than traditional single-screw presses, significantly reducing your cost per ton of oil produced.
✅ Multi-Seed Compatibility – Works with peanuts, soybeans, sunflower seeds, rapeseed, sesame, palm kernel, jatropha, and more.
✅ Low Maintenance – The main body and press chamber are made of high-grade nodular cast iron, providing excellent wear resistance and stability even under continuous heavy-load operation (24/7 production).
✅ Compact & User-Friendly – With a footprint of just 0.9 square meters, the YZS-68 is a compact oil press that can easily be placed in a workshop, garage, or retail store. Its intuitive push-button controls and built-in thermometer make it easy for even first-time users to operate.

Oilseed Pretreatment—The Key to Achieving Maximum Pressing Efficiency
Achieving the highest oil yield and the best-quality oil depends largely on pretreatment. Here’s a scientific breakdown of recommended preparation steps:
Standard Pretreatment Process (Suitable for Most Oilseeds):
- Cleaning—Remove stones, metals, and dust using a magnetic separator and vibrating screen to protect the screw and cage bars from abrasive damage.
- Drying — Adjust the moisture content to 6–10% (the ideal range for screw pressing). Excessive dryness results in low oil yield; excessive moisture causes slippage and cake fragmentation.
- Dehulling/Cracking—For oilseeds such as sunflower seeds and soybeans, dehulling reduces fiber content, increases oil yield by 5–8%, and raises the protein concentration in the meal.
- Flaking—Press the oilseeds into thin flakes (0.3–0.5 mm) to break down cell walls, thereby facilitating oil release during the pressing process.
- Cooking/Conditioning—Sunflower seed flakes are heated to 80–110°C for 20–40 minutes to denature proteins, reduce oil viscosity, and inactivate lipases (which cause oil rancidity). This step is critical in the sunflower seed oil pressing process, ensuring the production of oil with a bright color and stable properties.
Seed-Specific Protocols:
| Oilseed | Recommended Pre-Treatment |
|---|---|
| Sunflower | Dehull (optional) → Dry to 8% moisture → Flake → Condition at 90°C → Press (choke gap 4–6 mm) |
| Soybean | Clean → Crack into 4–6 pieces → Dehull → Condition at 75°C → Flake → Press (gap 3–5 mm) |
| Rapeseed | Clean → Pre-heat to 60°C → Flake (0.4 mm) → Cook at 100°C for 30 min → Press (gap 5–7 mm) |
| Palm Kernel | Dry to 7% moisture → Crack → Steam-condition at 95°C → Press (gap 2–4 mm, slower feed) |
Technical Note: For cold-pressed sunflower oil (premium market), skip cooking and press at ambient temperature (25–30°C) – our YZS-100 can handle this with a reduced feed rate, yielding a naturally golden oil with higher antioxidant content (tocopherols and phytosterols).
