| Residual oil in cake | 6–8% typical with the bar-type slotted barrel |
| Working mode | Manual / semi-automatic, one-button switch |
Actual daily output depends on seed, batch size and staff rhythm — not a guaranteed figure. Tell us your seed and target tons per day and we will calculate your throughput.
Single Barrel or Double Barrel? Your Choice
| Single barrel | Focused batch work — lower entry cost, same 620-ton force and 75 MPa pressure |
| Double barrel | One barrel presses while the other unloads & refills — no idle time, higher daily output |
| Both options | Same frame and barrel platform — start single, upgrade to double whenever output grows |
Power & Installation
Runs on a standard 380V / 50Hz supply (2.2 kW motor); other voltage standards can be customized. Generator-friendly: a 7 kVA generator is enough. The installation floor must support at least 4 tonnes with 3 m ceiling height — a reinforced concrete foundation is recommended.
Which Hydraulic Oil Press Model Fits Your Mill?
| Model | Force | Cake pressure | Barrel Ø (standard) | Configuration | Best for |
|---|---|---|---|---|---|
| HN300 | 300 t | 42 MPa | Ø300 mm | Single / double barrel | Smaller batches (~60 kg), tightest budget |
| HN325 | 325 t | ≈27 MPa | Ø390 mm (customizable) | Single / double barrel | Small & mid-size mills, all-purpose |
| HN365 | 365 t | 30 MPa | Ø390 mm (customizable) | Single / double barrel | Higher daily volume, hard seeds |
| HN426 | 500 t | 42 MPa | Ø390 mm (customizable) | Single / double barrel | Cold press business: coconut, walnut |
| HN500 | 620 t | 52 MPa | Ø390 mm (customizable) | Single / double barrel | Industrial scale, hardest in-shell materials |
HN426 or HN500? Both are high-force presses. The HN426 is tuned for cold-pressed premium oils; the HN500 adds force and pressure for the hardest in-shell materials — walnut in shell, apricot kernel, yellowhorn — and maximum daily volume.

Frequently Asked Questions
What is the oil yield of the HN500 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 HN500's 620-ton pressing force and bar-type slotted tabung press design achieve approximately 2-3% higher yield (based on Haonuo factory tests with graded sesame and peanut at 6-8% moisture; results vary with seed variety and preparation) than traditional drilled tabung press presses.
What raw materials can the HN500 press?
The HN500 can press sesame, peanut, rapeseed, sunflower seed, flaxseed, tea seed, soybean, cottonseed, and more. It excels at cold pressing the hardest materials including in-shell walnuts, apricot kernels, and yellowhorn.
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 optimal 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 is the difference between single and double tabung press configurations?
A single tabung press press processes one batch at a time. A double tabung press press has two tabung press on sliding rails — while one tabung press is pressing, you can load the other, nearly doubling your throughput. We recommend the double tabung press for commercial and industrial operations.
What power supply does the HN500 require?
The HN500 requires 2.2 KW motor power and runs on a standard 380V/50Hz supply. The electrical system can be customized to match your local power standards — simply specify your voltage when ordering.
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 the HN500, this includes specific coverage for the 5 cm thick steel plate frame, ultra-high pressure hydraulic pump, and heavy-duty cylinder assembly. 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 production time — 15-25 working days for standard models and 30-45 days for custom or special configurations (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 the HN500, ensure your installation floor can support at least 4 tonnes and has a minimum ceiling height of 3m. We recommend a reinforced concrete foundation. 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 the HN500, the full-load test is conducted at 75 MPa system pressure with 620 tonnes of pressing force — the highest in our product line.
Can the tabung press size be customized?
Yes, tabung press inner diameter and height can be customized to match your specific material and batch size requirements. Common customizations include larger tabung press for bulk materials and food-grade stainless steel tabung press 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 tabung press design, compared to 10-12% with traditional drilled tabung press presses. This means you extract approximately 2-3% more oil (based on Haonuo factory tests with graded sesame and peanut at 6-8% moisture; results vary with seed variety and preparation) from every batch.
Can the machine operate on generator power?
Yes, our machines are fully compatible with generator power. For the HN500, we recommend a minimum 7kVA generator. The machine starts easily and runs stably on generator power, making it suitable for areas with unreliable electricity supply such as rural Nigeria, Kenya, and other African regions.
Do you provide voltage customization for different countries?
Yes, the electrical system can be customized to match your local power supply. Simply specify your local voltage when ordering.
How quickly can I get spare parts in Africa or the Middle East?
We maintain stock of all common spare parts (seals, filter cloth, hydraulic oil, control panel components). Standard parts ship promptly via DHL/FedEx, arriving in 5-7 days to most African and Middle Eastern countries.
