Frequently Asked Questions

SinoOil Machinery is a professional manufacturer of edible oil processing equipment based in Zhengzhou, China. We design, manufacture, and export oil press machines, oil filtration systems, oil refinery plants, and complete turnkey edible oil processing lines from 1 TPD to 500 TPD capacity. Since 2009, we have delivered 500+ projects across 80+ countries in Africa, Asia, the Middle East, and South America.

There is no minimum order quantity. We supply single machines (one oil press, one filter press) as well as complete turnkey plants. Even a 1 TPD mini oil press installation is welcome. However, our strongest expertise is in complete plant projects (10 TPD and above) where we provide design, equipment, installation, and training.

If your country is not listed, contact us — we likely have experience there as well.

Yes. We offer OEM manufacturing for qualified international distributors — minimum order 10 machines per model per production run. OEM includes custom nameplate design, brand colour, and packing marks. Lead time: 45–60 days. Contact us to discuss OEM terms and pricing.

Our equipment processes all major oilseeds. Typical oil content percentages:

We also process specialty seeds including black seed (Nigella sativa), moringa, flaxseed, and others. Tell us your material and we'll specify the right equipment.

The 6YL series screw oil presses differ in barrel diameter and throughput capacity:

All models share the same screw-press operating principle but are optimized for different seed types and throughputs. Multiple units run in parallel for higher capacities.

A SinoOil turnkey plant package includes:

• Plant layout design and process flow diagram
• All processing equipment with model numbers specified
• Electrical control panels (PLC or manual)
• Installation drawings and operation manuals
• Pre-shipment factory testing of all equipment
• On-site installation and commissioning by SinoOil engineers
• Operator training (5–7 days on-site)
• 12-month equipment warranty
• Lifetime after-sales technical support via WhatsApp, email, and video call

Yes, with some limitations. Most 6YL screw presses can process compatible seed types — for example, the same 6YL-160 can process peanut, sunflower, and rapeseed. Switching between seed types requires changing the press screw configuration and adjusting conditioning parameters (different temperature, moisture settings). For very different materials (e.g., sesame vs soybean), dedicated presses are recommended for optimal yield. We advise on configuration based on your specific material mix.

SinoOil equipment carries: ISO9001:2015 (quality management system), CE marking on all electrical components (European safety compliance), SGS factory verification. Our factory is certified by the Chinese Ministry of Commerce as a qualified exporter. All electrical components meet IEC international standards and are configurable for local voltage specifications (380V/415V/440V, 50Hz/60Hz).

TPD means Tonnes Per Day of raw material input. To calculate your required capacity:

1. Estimate how many tonnes of oil you can sell monthly
2. Divide by oil yield % to get seed input needed
3. Divide by 25 operating days = TPD

Use our free Capacity Calculator at oilprocessingtech.com/free-plant-design/capacity-calculator/ or contact us for a calculation specific to your material and market.

Crude oil is the raw pressed oil containing FFA (1–5%), phospholipids, colour pigments, and volatile compounds. Refined oil (DBDW process) has FFA <0.1%, neutral colour and odour, and extended shelf life.

• You need a refinery if: selling to retail consumers, food manufacturers, or export markets; competing with imported refined cooking oil; output needs shelf life of 12+ months.
• You don't need a refinery for: artisan/premium cold-pressed oils where natural character is valued; selling crude to a downstream refinery; traditional markets comfortable with crude/natural oil.

Most of our equipment is configured for:

• 380V / 3-phase / 50Hz — standard for most of Africa, Asia, Middle East
• 415V variants available — UK standard, common in East Africa
• 440V/60Hz available for Americas

Power consumption varies by plant scale: 10 TPD peanut plant ~45–60 kW; 30 TPD soybean plant ~120–150 kW; 100 TPD continuous refinery ~300–450 kW. For areas with unstable grid supply (common in Africa and Southeast Asia), we include a voltage stabiliser (AVR) by default and provide generator connection points for backup power.

Typical screw press yields by seed type:

Actual yield depends on seed oil content (test your specific batch), seed moisture (optimal 8–12%), conditioning temperature, press speed, and equipment wear condition. We specify the expected yield for your exact raw material in every plant proposal.

Approximate floor space requirements:

Our free plant design service creates a layout optimized for your specific building dimensions. Share your building L×W×H and we'll design a complete plant layout within 48 hours.

Approximate FOB China price ranges:

These are FOB China prices. Add shipping ($2,000–$8,000), import duties (varies by country, typically 5–25%), and civil works (15–25% of equipment cost) for total delivered investment. Use our Budget Estimator at oilprocessingtech.com/free-plant-design/budget-estimate/ for a specific estimate.

Standard payment terms:

• 30% T/T (bank transfer) deposit upon order confirmation
• 70% T/T before shipment after pre-shipment inspection
• For large orders ($100,000+): Letter of Credit (L/C) at sight also accepted
• For clients with strong track records: installment arrangements may be possible

We do not accept 100%-on-delivery terms. We are transparent about this upfront — if a supplier offers 100% on delivery, verify their warranty and after-sales commitment carefully.

We don't publish a standard price list because every plant is customized to the client's raw material, capacity, building dimensions, output configuration, and local utility specifications. The same "30 TPD" plant may differ significantly based on whether it needs solvent extraction, an AVR stabilizer, a different boiler specification, or Arabic-language PLC.

Our quotations are already our best commercially competitive price based on current steel, copper, and component costs. We don't inflate prices for negotiation. However: we can adjust scope (e.g., exclude the refinery initially and add it later), offer volume pricing for repeat orders, and consider extended payment terms for established relationships. The most effective way to optimize cost: make sure the scope exactly matches your requirements — neither over-specified nor under-specified.

Lead times by order type:

• Stock machines (standard 6YL presses, filter presses): 7–15 days
• Custom/specified equipment: 30–60 days
• Complete turnkey plant packages: 45–70 days (manufacturing) + 25–35 days (sea freight to Africa/Asia) = 70–105 days total from order to arrival at your port

We provide production tracking updates and pre-shipment inspection photos/videos before each shipment.

Equipment is shipped by sea freight (FCL — full container load) from Qingdao or Shanghai port. Smaller orders may consolidate (LCL). Containers: 20ft HC for small plants, 40ft HC for medium plants, multiple containers for large plants.

Standard export documents: Commercial Invoice, Packing List, Bill of Lading, Certificate of Origin, and Export Declaration.

Additional documents on request: SGS inspection certificate, fumigation certificate, Form-E (ASEAN), EUR1 (Europe), and others.

We handle all export documentation from the China side. Customs clearance at the destination country is the buyer's responsibility — we strongly recommend using a local freight forwarder or customs agent experienced in industrial machinery imports. We provide all necessary shipping documents and can advise on HS codes, product descriptions, and required certificates for your country. For first-time importers, we can recommend freight forwarders in your region based on our clients' experience.
