Description
Overview
The HN300 Mini Hydraulic Oil Press is our most compact and accessible hydraulic oil press, specifically designed as a dedicated sesame oil press machine. Also known as a small sesame oil mill or traditional-style sesame oil press, it is lightweight, easy to operate, and perfectly suited for sesame and small seed oil production. With 300 tons of pressing force and a 60 Mpa system pressure, the HN300 delivers reliable oil extraction in a space-saving footprint.
The HN300 cylinder paired with a 390 mm inner diameter barrel achieves a cake surface pressure of 25 Mpa/cm², providing sufficient pressure for sesame, peanut, rapeseed, and tea seed to be fully pressed in a single cycle. Its compact 1100×1100×2350 mm overall dimensions make it ideal for workshops with limited space, while the lightweight 1.2-ton single-barrel configuration allows for easy installation and relocation.

- Dual-Barrel Option — Double-barrel configuration available for operators who want to increase throughput without a larger footprint.
Core Technology
- Bar-Type Slotted Barrel — significantly more oil extraction area than drilled barrels, achieving approximately 2-3% higher oil yield (based on internal testing, results vary) per batch.
- German Hydraulic System — Ultra-high pressure combined pump delivers working pressure up to 60 Mpa for consistent, powerful extraction.
- 4-Hook Cake Removal — Easy, reliable cake discharge system that reduces downtime between pressing cycles.
- High Carbon Steel Frame — Long-lasting service under continuous operation. Actual service life depends on operating conditions and maintenance.
- Microcomputer Control — Automated pressing cycle with one-button operation. Basic training recommended; we provide video tutorials and remote guidance.
- 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
The HN300 is ideal for pressing sesame and other small oil seeds:
- Best For: Sesame (the primary application), producing authentic aromatic sesame oil
- Also Suitable: Peanut, rapeseed, tea seed
- Other Materials: Similar small seeds and conventional pressing materials
Note: For hard-shell or cold-press materials such as walnuts or apricot kernels, consider our HN426 Cold Press model or HN500 Ultra High Pressure model.

Frequently Asked Questions
What is the oil yield of the HN300 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 HN300's 300-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 HN300 press?
The HN300 can press sesame, peanut, rapeseed, sunflower seed, flaxseed, tea seed, soybean, cottonseed, and more. It is specifically optimized as a dedicated sesame oil press machine. For hard-shell materials like walnuts and almonds, we recommend our cold press or ultra-high pressure models.
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 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 HN300 require?
The HN300 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 the HN300, this includes specific coverage for the compact hydraulic unit and single-barrel 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 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 the HN300, the compact design fits through standard doorways (under 1.2m wide) and requires only a standard 220V outlet. 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 HN300, the full-load test is conducted at 60 Mpa system pressure with 300 tonnes of pressing force.
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.
