02 โ€” COMPLETE LINES

Our Product Range

Everything you need to extract oil, from a single press to a full production line. Our cold pressed oil machine runs both cold and hot pressing on one machine.

04 โ€” PRESS ANATOMY

Seven Parts Take the Load

The parts that fail cheap presses are the cylinder, barrel and valve block. This is exactly where Haonuo spends the steel.

Diagram of the seven core components inside a Haonuo hydraulic press
01

Hydraulic Cylinder

27SiMn alloy steel (GB/T 3077), rated for 60โ€“75 MPa system pressure and 300โ€“620 tonnes of pressing force.

02

Oil Pressure Plate

Transfers the cylinderโ€™s force evenly over the whole seed cake, so pressure reaches every seed uniformly instead of concentrating in the centre.

03

Material Bucket

Q690 high-strength steel, welded and nickel-plated inside and out. Strip-slotted walls release oil faster than a conventional drilled barrel, with no bare metal touching the seed.

04

Oil Outlet

Pressed oil collects here after draining through the bucket walls and runs straight into the tray below; the outlet is nickel-plated for food-grade contact.

05

Control Panel

Pressure gauges, adjustable cycle timer and safety interlocks grouped on one button-controlled panel.

06

Directional Control Valve

Electroplated valve block with enlarged ports for fast, smooth cycle switching.

07

Hydraulic Oil Tank

Built-in oil tank with filter and cooling keeps system oil clean and at a stable temperature.

05 โ€” FACTORY DIRECT

Built, Then Run Under Pressure, Before It Leaves

No trading company and no showroom stock. Welding, assembly, control cabinets and load testing happen in our own Qingzhou workshop โ€” buyers are welcome to inspect in person before their machine ships.

01

Full-pressure test

Every press is run to working pressure and checked for leaks before packing.

02

Spare parts included

Wear parts ship with the order so day-one failures never stop the line.

03

English manual & support

Printed English manual with remote guidance from our own engineers by email and chat.

04

On-site installation

Engineer installation available overseas; buyer covers travel and accommodation.

06 โ€” QUESTIONS

Frequently Asked Questions

How do I pick the right press model for my seeds?

Start from your raw material and your daily output target. Small shops working sesame or peanut usually run the HN300 or HN325; hard, low-oil seeds such as walnut or camellia call for the HN365 or above, while the HN426 and HN500 fit high-volume plants. Send us your seed type and target capacity and we will size the machine honestly โ€” not upward.

What is the difference between cold pressing and hot pressing?

Cold pressing skips roasting, keeps oil temperature low and preserves natural nutrients and a light flavor preferred by premium markets, though the yield is smaller and downstream refining is often needed. Hot pressing roasts the seed first, extracting more oil with a stronger aroma for mainstream cooking oil. Every Haonuo model runs both processes.

How long does production take after I order?

Standard configurations are normally completed within 15โ€“25 working days after the deposit arrives; custom setups may take 30โ€“40 days depending on workshop load. Your confirmed loading window is written into the proforma invoice.

Do you provide installation and operator training?

Most single-press buyers install the machine themselves using the printed English manual and our online support. For complete lines, a Haonuo engineer can travel to your site for installation and training; the buyer covers flights, visa, accommodation and a daily service fee.
