Oil Pressing Line — The Heart of Oil Production
Screw, hydraulic and cold-press systems that convert prepared oilseeds into high-yield crude oil — the core extraction stage of every edible oil plant.
Why Oil Pressing Is the Core Stage
Mechanical extraction determines your oil yield, crude oil quality and overall plant economics — making press selection and line design critical
Maximize Oil Yield
Proper press type, temperature and screw configuration extract 90–97% of available oil from prepared seeds — directly impacting revenue per ton of raw material.
Continuous Production
Screw and commercial press lines run continuously for high daily throughput. Stable feed and automated cake discharge keep labor costs low on commercial scales.
Flexible Press Types
Match equipment to your market: hot screw pressing for volume, hydraulic for specialty sesame oil, or cold press for premium health-oriented retail products.
Quality Crude Oil
Controlled pressing temperature and filtration-ready crude oil support downstream refining or direct bottling — with consistent color, aroma and FFA levels.
Oil Pressing Equipment
From single workshop presses to multi-press industrial lines — configured for peanut, soybean, sunflower, sesame, rapeseed and more
Screw Oil Press
Continuous 6YL-series screw press for high-capacity extraction — ideal for peanut, soybean, sunflower and rapeseed on commercial and industrial lines.

Hydraulic Press
Static pressure HYJ-series press for sesame, walnut and specialty oils — delivers premium oil clarity and very high extraction on low-volume batches.
View Equipment →
Cold Press
Low-temperature screw press retains natural nutrients and flavor — suited for health-food markets, organic certification and premium retail branding.

Pressing Methods
Compare screw, hydraulic and cold pressing to choose the right extraction technology for your oilseed, capacity and target market
| Parameter | Screw Press | Hydraulic Press | Cold Press |
|---|---|---|---|
| Principle | Continuous screw extrusion | Static hydraulic pressure | Low-temp screw extrusion |
| Typical capacity | 80–600+ kg/h per unit | 30–80 kg/h per batch | 50–300 kg/h per unit |
| Oil yield | High (90–95%+) | Very high (95–97%) | Medium–high (85–92%) |
| Pressing temperature | Hot (60–100°C) | Warm (40–60°C) | Cold (<45°C) |
| Best for | Commercial & industrial mills | Sesame, walnut, specialty oils | Health food, organic retail |
| Automation | High — continuous feed | Semi-auto — batch cycles | Medium — continuous/low-temp |
| Investment level | Medium | Low–medium | Medium–high |
Many plants combine a pre-press screw with a main press for high-oil seeds, or pair screw extraction with hydraulic finishing for premium products. Our engineers recommend the optimal mix based on your oilseed and daily TPD target.
The Pressing Process
Three integrated steps from conditioned seeds to collected crude oil ready for filtration or refining
Prepared seeds from the seed preparation line feed into the press. Extracted crude oil moves to filtration or refining, while press cake can be sold as animal feed or further processed.

Frequently Asked Questions
Screw presses suit high-volume commercial production for peanut, soybean, sunflower and rapeseed. Hydraulic presses excel for sesame, walnut and specialty oils where oil clarity and maximum yield per batch matter more than throughput. We often recommend screw pressing for main production and hydraulic for premium product lines.
Yield depends on oilseed type, preparation quality and press configuration. Well-prepared peanut and sunflower typically achieve 90–95% extraction on screw presses; sesame on hydraulic presses can reach 95–97%. Cold pressing trades 3–8% yield for lower temperature and higher nutrient retention.
Yes, for almost all oilseeds. Cleaning removes stones and metal that damage press screws. Roasting or conditioning optimizes moisture for maximum yield. Pressing unprepared seeds reduces extraction rates, increases wear and produces inconsistent crude oil quality. We supply integrated prep + pressing lines.
A single workshop screw press may start from USD 3,000–8,000. A complete 5–20 TPD commercial pressing line with conveyors, collection tanks and installation typically ranges from USD 25,000–60,000. Industrial multi-press plants are quoted individually. We provide itemized quotations after reviewing your oilseed, capacity and site layout.
Most screw presses process multiple oilseeds with die and temperature adjustments. Switching between crops may require cleaning time and minor part changes. Hydraulic presses are often dedicated to one specialty crop. Tell us your primary and secondary oilseeds — we configure presses and spare parts accordingly.
