Description
Overview
The HN480 High Pressure Hydraulic Oil Press bridges the gap between our HN426 cold-press specialist and the HN500 ultra-high-pressure flagship. With a 480 mm cylinder diameter and an estimated 560-ton pressing force at 72 Mpa system pressure, it delivers substantial power for both conventional and cold-press oil extraction — an optimal balance of performance and value for medium-to-large-scale operations.
Key Advantages
- Balanced Performance — Positioned between the HN426 and HN500, offering strong pressing force without the premium of the flagship model.
- Cold-Press Capable — Sufficient cake pressure for cold pressing walnut kernels, apricot kernels, and similar materials.
- Versatile Application — Handles both conventional oil seeds and cold-press materials with reliable oil yield.
- Energy Efficient — 2.2 KW motor keeps operating costs low while delivering industrial-grade pressing force.
Core Technology
- Bar-Type Slotted Barrel — Haonuo’s proprietary slotted barrel design provides significantly more oil extraction area than traditional drilled barrels. Oil flows faster and clearer, with approximately 2-3% higher yield (based on internal testing, results vary). No clogging, no cleaning between batches.
- German Hydraulic System — Ultra-high pressure combined hydraulic pump station with high-low dual pump. Working pressure up to 72 Mpa with rapid cylinder return.
- 4-Hook Cake Removal — Innovative 4-hook mechanism ensures easy, reliable cake discharge — even after overnight pressing.
- High Carbon Steel Frame — High-frequency quenched and heat-treated steel for long-lasting service. Actual service life depends on operating conditions and maintenance under 560-ton pressing force.
- Microcomputer Control — Automated pressing cycle from loading to finished oil in minutes.
- Energy Efficient — Designed to reduce power consumption compared to previous-generation presses (actual savings vary by operating conditions).
- Labor Efficient — Only 1-2 operators needed, reducing labor requirements compared to manual pressing methods.
Applications & Suitable Materials
- Oil Seeds: Tea seed, rapeseed, peanut
- Cold-Press Materials: Walnut kernel, apricot kernel

Frequently Asked Questions
What is the oil yield of the HN480 hydraulic oil press?
The oil yield depends on the raw material. For example, sesame yields 42-54%, peanuts 40-50%, and rapeseed 35-45%. The HN480's 560-ton pressing force and bar-type slotted barrel design achieve approximately 2-3% higher yield (based on internal testing, results vary) than traditional drilled barrel presses.
What raw materials can the HN480 press?
The HN480 can press sesame, peanut, rapeseed, sunflower seed, flaxseed, tea seed, soybean, cottonseed, and more. It also handles cold-press materials like walnut kernels and apricot kernels effectively.
How long does one pressing cycle take?
Hot pressing (with pre-roasting) completes in 30-40 minutes per batch. Cold pressing takes approximately 2 hours to preserve oil quality at low temperatures. The actual cycle time depends on factors like seed moisture content, desired cake dryness, and pressing temperature. The microcomputer control system automates the entire process from feeding to cake discharge.
What is the recommended raw material moisture content for pressing?
The optimal moisture content varies by material type and pressing method. For hot pressing, we recommend 5-8% moisture before roasting, with the roasted material reaching 3-5% moisture. For cold pressing, the ideal range is 7-9% moisture. Proper moisture control is critical — too high causes oil emulsification and yield loss, while too low increases friction and reduces throughput.
What pre-processing equipment is needed before the hydraulic press?
Complete oil production typically requires several pre-processing stages including seed cleaning and sorting to remove impurities and damaged seeds, dehulling for high-shell-content materials like peanuts with shell removal rate at least 95 percent, moisture conditioning to reach optimal levels, roasting for hot pressing at 160-180 degrees Celsius to develop flavor and color, and seed crushing for improved oil flow. The press itself is the core, but pre-processing directly impacts oil yield and quality.
What is the difference between single and double barrel configurations?
A single barrel press processes one batch at a time. A double barrel press has two barrels on sliding rails — while one barrel is pressing, you can load the other, nearly doubling your throughput. We recommend the double barrel for commercial and industrial operations.
What power supply does the HN480 require?
The HN480 requires 2.2 KW motor power, compatible with both 220V/50Hz and 380V/60Hz power supplies. We can customize the electrical system to match your local power standards at no extra charge.
How many workers are needed to operate the machine?
Only 1-2 workers are needed. The microcomputer control system automates the pressing cycle, and the 4-hook cake removal mechanism makes unloading easy even after overnight pressing.
What warranty do you provide?
We provide a 1-year warranty covering all manufacturing defects, plus lifetime technical support. For this high-pressure model, this includes specific coverage for the 63 Mpa rated hydraulic pump and reinforced cylinder seals. Spare parts are available from stock.
How is the machine shipped and how long does delivery take?
The machine is shipped in a wooden crate via sea freight. Delivery to most Asian ports takes 15-20 days, to African ports 25-35 days, and to South American ports 30-40 days. This is in addition to 20-30 working days production time (shipping time additional). Air freight is available for urgent orders.
Do you provide installation and training?
Yes, we provide detailed installation manuals, video tutorials, and remote technical guidance. For this high-pressure model, ensure your installation floor can support at least 2 tonnes and verify local pressure vessel compliance requirements. For large orders, we can send a technician to your facility for on-site installation and training at cost.
What certifications does the machine have?
All machines undergo 48-hour continuous full-load testing before shipment. For this high-pressure model, the full-load test is conducted at the maximum rated 63 Mpa to verify seal integrity and structural performance.
Can the barrel size be customized?
Yes, barrel inner diameter and height can be customized to match your specific material and batch size requirements. Common customizations include larger barrels for bulk materials and food-grade stainless steel barrels for edible oil production.
What is the residual oil rate in the cake?
The residual oil rate in the cake is typically 6-8% for most materials with our bar-type slotted barrel design, compared to 10-12% with traditional drilled barrel presses. This means you extract approximately 2-3% more oil (based on internal testing, results vary) from every batch.
