Description
Overview
The Sesame Oil Hydraulic Press is a purpose-built hydraulic oil press machine designed specifically for sesame oil extraction. Sesame pressing demands strict temperature control — to prevent heat loss and reduced oil yield, pressing must be completed in the shortest possible time. This model pairs the HN325 or HN355 cylinder with a narrower 300 mm inner diameter barrel, concentrating the pressing force to achieve 47–51 Mpa/cm² cake surface pressure, allowing sesame to be fully pressed clean in a single rapid cycle.
The 300 mm inner diameter, 800 mm high barrel holds 32.5 kg of sesame per batch. With pre-compression to create additional space, a single batch can process up to 50 kg of sesame — significantly more than Korean-style hydraulic sesame oil presses, offering superior capacity and value for money.
Key Advantages
- Optimized for Sesame — Narrower 300 mm barrel concentrates pressing force to 47–51 Mpa/cm², achieving complete sesame oil extraction in a single fast cycle.
- Temperature-Sensitive Design — Rapid pressing cycle minimizes heat loss, preserving sesame oil quality and maximizing oil yield.
- Large Batch Capacity — 32.5 kg standard load, up to 50 kg with pre-compression — far exceeding Korean-style sesame oil presses in single-batch capacity.
- Versatile Performance — Also excels at pressing in-shell walnuts (except iron walnuts) in approximately 30 minutes per batch, and delivers even lower residual oil rates on conventional materials.
- Two Power Options — Available in HN325 (47 Mpa/cm²) and HN355 (51 Mpa/cm²) configurations to match your production needs and budget.
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) — vital for sesame where rapid, complete extraction preserves quality and maximizes output. 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 60/63 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 325/360-ton pressing force.
- Microcomputer Control — Automated pressing cycle from loading to finished oil in minutes — critical for sesame’s temperature-sensitive pressing cycle.
- 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.

Frequently Asked Questions
What is the oil yield of the Sesame Oil Hydraulic Press?
The oil yield for sesame is 42-54% depending on the variety and moisture content. The narrower 300 mm barrel concentrates pressing force to 47–51 Mpa/cm² cake surface pressure, achieving complete sesame oil extraction in a single fast cycle with approximately 2-3% higher yield (based on internal testing, results vary) than traditional drilled barrel presses.
What raw materials can the Sesame Oil Hydraulic Press press?
The Sesame Oil Hydraulic Press is specifically optimized for sesame oil extraction. It also excels at pressing in-shell walnuts (except iron walnuts) in approximately 30 minutes per batch, and handles tea seed, rapeseed, peanut, soybean, lacquer oil seed, and flaxseed with even lower residual oil rates than standard models.
How long does one pressing cycle take?
A typical hot pressing cycle takes 30-40 minutes for sesame depending on the desired cake dryness and moisture content. The rapid cycle is critical for sesame's temperature-sensitive pressing — minimizing heat loss preserves oil quality and maximizes yield. For cold pressing, the cycle takes approximately 2 hours. The microcomputer control system automates the entire process from feeding to cake discharge.
What is the recommended raw material moisture content for sesame pressing?
For sesame hot pressing, we recommend 5-8% moisture content before roasting. The roasted sesame should reach 3-5% moisture for optimal oil extraction. For cold pressing, the ideal range is 7-9% moisture. Proper moisture control is critical for sesame — too high causes oil emulsification, while too low increases friction and reduces yield.
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 Sesame Oil Hydraulic Press require?
The Sesame Oil Hydraulic Press 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 Sesame Oil Press, this includes specific coverage for the narrow-gap barrel assembly and temperature-sensitive pressing system. 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 large orders, we can send a technician to your facility for on-site installation and training at cost. For the sesame model, we recommend installing near your seed cleaning area to minimize sesame seed handling and prevent contamination.
What certifications does the machine have?
All machines undergo 48-hour continuous full-load testing before shipment. For the Sesame Oil Press, the full-load test includes sesame pressing cycle verification, confirming consistent oil yield across multiple batches.
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.
