Medium Hydraulic Oil Press: Description

Overview

Looking for the current model? The HN365 is the upgraded successor to the HN355 — 365 t pressing force, 30 MPa cake pressure, and a new vertical double-station frame with 3 cm steel plate and cartridge valves. Most buyers today choose the HN365. The HN355 remains in production for buyers replacing an existing HN355 or matching a previous quotation.

The HN355 is a 360-ton medium hydraulic oil press with a 355 mm cylinder and 390 mm tabung press, delivering 30.15 MPa cake surface pressure. It processes up to approximately 100 kg of raw material per batch. The 2.2 kW motor keeps operating costs modest, and the machine runs on standard 220V/380V power.

This page serves as a reference for buyers searching specifically for the HN355 by model number — for example, to match an existing machine or compare specs against a previous quotation. The HN355 shares its tabung press and common wear parts with the HN365, so spare parts remain available.

Choose the HN355 if:

  • You are replacing an existing HN355 and want spare-part compatibility
  • You are matching a previous quotation that specifies the HN355
  • You prefer the classic single/double tabung press layout

Choose the HN365 if:

  • You want the current upgraded model with the vertical double-station frame
  • You need cartridge valves for better hydraulic control
  • You want the model most buyers choose today

Suitable Applications

The HN355 handles conventional oilseeds that benefit from medium pressing force:

  • Best for: Tea seed, rapeseed, peanut, soybean
  • Also suitable: Flaxseed, lacquer oil seed, cottonseed
  • Not recommended: Walnut, almond, and other hard-shell cold-press materials — see the HN426 Cold Press or HN500 Ultra High Pressure instead

Still in Production

The HN355 is still manufactured and accepts orders. It shares the same tabung press and common wear parts as the HN365, so spare parts remain available from stock. Production lead time is 15–25 working days for standard configurations.

Medium Hydraulic Oil Press — Frequently Asked Questions

What is the oil yield of the HN355 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 HN355's 360-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 HN355 press?
The HN355 can press sesame, peanut, rapeseed, sunflower seed, flaxseed, tea seed, soybean, cottonseed, and more. 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 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 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 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 HN355 require?
The HN355 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 HN355, this includes specific coverage for the reinforced cylinder assembly and high-pressure hydraulic 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 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 HN355, ensure your installation floor can support at least 2 tonnes and has adequate ventilation for continuous operation. 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 HN355, the full-load test is conducted at 63 MPa system pressure with 360 tonnes of pressing force.
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. For the HN355, the standard tabung press has an inner diameter of 390 mm and height of 800 mm.
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. With the HN355's 30.15 MPa cake surface pressure, you can expect results in the lower end of this range for most conventional materials.
Can the machine operate on generator power?
Yes, our machines are fully compatible with generator power. For the HN355, we recommend a minimum 5.5kVA 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, we customize the electrical system to match your local power supply at no extra charge. Common configurations include 220V/50Hz (Southeast Asia, Africa, Middle East), 110V/60Hz (Philippines, parts of South America), and 380V/50Hz (industrial three-phase). 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.
