Africa (Nigeria, Kenya, Ghana, Tanzania): The HN500 is built for industrial-scale groundnut and shea butter processing. Its robust frame and heavy-duty hydraulic system withstand continuous 12-hour daily operation common in African production facilities.
Middle East (Saudi Arabia, UAE, Egypt): The HN500 is our top recommendation for walnut oil (زيت الجوز) and high-value nut oil production. The ultra-high pressure extracts maximum oil from hard-shelled nuts while the temperature control system preserves delicate omega-3 fatty acids.
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 barrel design achieve approximately 2-3% higher yield (based on internal testing, results vary) than traditional drilled barrel 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 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 HN500 require?
The HN500 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 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 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 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 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.
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, 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. For Nigeria, we also work with local agents in Lagos who carry commonly needed parts.
