WHAT IT IS

What is a hydraulic oil press machine?

A hydraulic oil press is a batch-type oil extraction machine that packs prepared oil seeds into a bar-slotted barrel (reinforced flange rings welded with trapezoidal steel bars, 1 mm inner slots and about 1 cm outer slots) and crushes them with a hydraulically driven piston — 300 to 620 tons of static force, at system pressures of 60–75 MPa. Oil flows out through the barrel slots while the seed cake stays inside.

Unlike a screw (expeller) press, there is no rotating screw and no friction heat. The same machine runs cold pressing (raw, dried seed — oil stays below 60°C) and hot pressing (pre-roasted or steamed seed for a few extra yield points); you only change how the seed is prepared.

Typical capacity is up to 100 kg of seed per barrel per cycle, served by one or two workers and a single 2.2 kW motor — a practical fit for small-to-medium oil mills, premium-oil producers and full production lines alike.

Figures vary by model, seed variety and moisture content (typical factory test range 6–8%). We confirm exact specs for your material before order.

Naturally cold-press capable

Static pressure means no friction heat — no heating element is needed to keep cold-pressed oil below 60°C.

Runs almost anywhere

A 2.2 kW motor works on standard single-phase supply or a 5–7 kVA generator — proven in rural off-grid areas.

Bar-slotted barrel, +2–3% yield

The bar-type slotted barrel extracts roughly 2–3% more oil than conventional drilled barrels (factory test, sesame & peanut).

How a Hydraulic Oil Press Works

1

Load Seeds

Fill the press barrel with prepared oil seeds. Most seeds benefit from cleaning and drying; hot-pressed seeds are usually roasted or steamed first, while cold-pressed seeds are loaded raw.

2

Apply Pressure

The hydraulic system generates up to 620 tons of pressing force at controlled temperatures below 60°C for true cold pressing.

3

Collect Oil

Pure, filtered oil flows out through the slotted barrel while the compressed seed cake is ejected automatically by the 4-hook mechanism.

CHOOSE BY YOUR SEED

Which hydraulic press do you need?

You do not need to memorize model numbers — start from your seed and your daily volume. Each path below links to the exact model page with full specs. The full parameter matrix lives in one place: the model comparison page.

Entry level

Soft & medium seeds, small-to-medium workshops

Sesame · peanut · rapeseed · sunflower · soybean · tea seed

300–365 tons pressing force

The best-selling daily-oil machines. One-button cycle, 2.2 kW motor (runs on a 5–7 kVA generator), single- or double-barrel stations.

Food grade

Coconut milk, VCO & export-grade food production

Coconut milk · VCO · halal / food-certified sesame

300–325 tons · 304 stainless steel

Full food-contact 304 stainless barrels and frames for wet pressing and audited export facilities.

Cold press

Premium oils from medium-hard seeds & nuts

Walnut · almond · camellia / tea seed · flaxseed · apricot kernel

500–600 tons · 42–48 MPa cake pressure

High cake-surface pressure is what cold pressing needs. Static pressure adds no friction heat, so raw dried seed presses below 60°C.

Industrial

Hard / in-shell materials & high-volume mills

Copra · in-shell walnut · tiger nut · shea · yellowhorn · hemp

620 tons · up to 75 MPa system pressure

The highest force in the range for the hardest materials; double-barrel configurations for continuous high throughput.

The HN300–HN500 force range

Harder seed or in-shell material → higher cake pressure required. Tap a model for its page.

Is a hydraulic press right for your business?

Hydraulic presses give high pressure, low temperature and batch pressing — ideal for premium cold-pressed oils and for mills that switch between seeds and methods. Continuous screw lines or solvent extraction can fit very high-volume refining operations better. Before you buy, compare the trade-offs honestly.

Hydraulic Oil Press Machine — Frequently Asked Questions

What is a hydraulic oil press machine?
A hydraulic oil press machine uses hydraulic pressure to extract oil from seeds and nuts. Unlike screw presses that generate heat through friction, hydraulic presses apply uniform static pressure at controlled temperatures, making them well-suited for cold pressing premium oils like sesame, walnut, and coconut oil. The process preserves natural nutrients, flavor, and aroma.
How does a hydraulic oil press work?
The machine uses a hydraulic pump to generate high pressure (up to 75 MPa) which drives a piston into a barrel filled with prepared oil seeds. The pressure squeezes oil out through a slotted barrel while the compressed seed cake remains inside. A typical pressing cycle takes 40-90 minutes. The microcomputer control system automates the entire process from pressing to cake discharge.
What seeds can a hydraulic oil press process?
Hydraulic oil presses can process 50+ types of oil seeds including sesame, peanut, coconut, walnut, almond, sunflower, flaxseed, mustard, rapeseed, tea seed, soybean, cottonseed, apricot kernel, and more. Different models are optimized for different seed types — smaller models for sesame and soft seeds, higher-pressure models for hard-shell nuts like walnut and almond.
What is the oil yield of a hydraulic oil press?
Oil yield varies by seed type: sesame 42-50%, peanut 38-45%, coconut 55-65%, walnut 50-60%, rapeseed 35-45%, sunflower 40-48%. Haonuo hydraulic presses use a proprietary bar-type slotted barrel design that achieves approximately 2-3% higher yield than traditional drilled barrel presses (based on Haonuo factory tests with graded sesame and peanut at 6-8% moisture; results vary with seed variety and preparation), with residual oil in cake as low as 6-8%.
How much does a hydraulic oil press machine cost?
Contact Haonuo for factory-direct pricing. We offer competitive rates with no middleman markup — saving compared to local distributors (actual savings vary). Pricing depends on the model, barrel configuration (single/double), and customization options. Request a quote and receive a detailed quotation including machine price, shipping, and estimated duties within 24 hours.
What is the difference between cold press and hot press?
Cold press operates below 60°C preserving nutrients, natural flavor, and aroma — well-suited for premium oils like sesame, walnut, and virgin coconut oil. Hot press involves roasting seeds before pressing, which increases yield slightly but may alter flavor and reduce nutritional value. Hydraulic oil presses are naturally suited for cold pressing because they apply static pressure without friction-generated heat.
Can the machine run on a generator?
Yes, Haonuo hydraulic presses only need 2.2 KW motor power, making them fully compatible with a 5-7 KVA generator. This makes them well-suited for areas with unstable or no grid electricity, such as rural Nigeria, Kenya, and other regions across Africa and Southeast Asia.
What warranty do you provide?
All Haonuo machines come with a 1-year warranty covering manufacturing defects, plus lifetime technical support. Spare parts are available from stock. Every machine undergoes 48-hour continuous full-load testing before shipment to ensure reliable operation.
