FAQ

Daily maintenance includes lubricating bearings and moving parts, inspecting press screws and cage bars for wear, cleaning filter screens and oil strainers, checking oil levels and operating temperatures, and removing residual fiber from the pressing chamber after each shift. Following these steps prevents unplanned downtime.

Press screws and cage bars typically need replacement every 3-6 months depending on processing volume and FFB quality. Signs of wear include decreased oil extraction efficiency, increased oil residue in fiber cake, and unusual vibration. We recommend keeping one set of spares on hand to avoid production interruptions.

Weekly maintenance includes checking steam valves and pressure gauges, cleaning the condensate drain, and inspecting the door seal and safety interlocks. Monthly, inspect the vessel body for corrosion and test the safety relief valve. Annual maintenance includes hydrostatic testing of the pressure vessel and replacement of worn seals and gaskets.

Daily checks include water level, steam pressure, and fuel feed rate. Weekly, inspect fire tubes and clean ash from the combustion chamber. Monthly, test safety valves and check water treatment chemical levels. Annual maintenance includes comprehensive tube inspection, refractory repair, and calibration of all instruments. Always follow local boiler safety regulations.

Prevent corrosion by maintaining oil temperature at 50-55°C to prevent moisture condensation, applying food-grade protective coatings to internal surfaces, regularly draining water from tank bottoms, and performing annual inspections for rust or coating damage. For carbon steel tanks, consider adding a stainless steel liner for long-term protection.

We offer both single screw and double screw palm oil press machines. The single screw press is suitable for small scale production (0.5-5 TPH), while the double screw press is designed for medium to large scale operations (1-100 TPH). Both types feature high oil extraction rates and continuous operation.

Our double screw palm oil press achieves an oil residue rate of less than 8% in the pressed fiber cake, while the single screw press achieves less than 10%. The actual rate depends on the quality of the raw material and operating conditions.

Our palm oil press machines are available in capacities ranging from 0.5 TPH to 100 TPH. Common models include YHX-10 (1-2 TPH), YHX-30 (5-10 TPH), YHX-60 (15-30 TPH), YHX-100 (30-60 TPH), and YHX-200 (60-100 TPH). Custom capacities can also be designed.

Our equipment is constructed using high-quality stainless steel for parts that contact the oil, and carbon steel for the frame and structural components. This ensures durability, corrosion resistance, and compliance with food safety standards.

Yes, we provide a complete set of spare parts with each equipment order. Additional spare parts can be ordered separately. We maintain a stock of commonly needed parts to ensure quick delivery.

A palm oil decanter is a horizontal centrifuge used to separate oil, water, and sludge from the press liquor. It improves oil recovery by over 90% and reduces the load on your clarification system. We recommend decanters for medium to large scale mills (15+ TPH) where maximizing oil yield and reducing effluent are priorities.

A palm oil filter press uses plate and frame filtration to remove fine impurities and suspended solids from crude palm oil after clarification. It produces cleaner oil with lower moisture and impurity content, which is important if you plan to refine the oil or sell to quality-conscious buyers.

Yes, EFB shredders and presses can be retrofitted to existing palm oil mills. Processing EFB reduces waste volume by up to 70%, recovers residual oil (2-3%), and produces shredded fiber that can be used as boiler fuel or for pellet production. Contact our engineering team for a site assessment.

POME (Palm Oil Mill Effluent) treatment is essential for environmental compliance in most countries. Our system uses anaerobic digestion followed by aerobic treatment to achieve >95% COD removal and >98% BOD removal. The biogas produced can be used for power generation, offsetting 30-40% of a mill's electricity needs.

The minimum investment for a 1-2 TPH small scale palm oil mill typically ranges from $50,000 to $100,000 USD, including equipment, installation, and basic infrastructure. The exact cost depends on local conditions and specific requirements.

For a well-managed palm oil mill, the expected return on investment is typically 12-18 months for small scale projects and 18-24 months for larger projects. The actual ROI depends on factors such as raw material cost, oil selling price, and operational efficiency.

Land requirements vary by capacity: a 1-5 TPH mill needs approximately 200-500 m², a 5-30 TPH mill needs 500-2000 m², and a 30-100 TPH mill needs 2000-5000 m². This includes the processing area, raw material storage, and CPO storage.

Our palm oil equipment is specifically designed for palm fruit processing. However, some of our presses can also process other oil seeds such as sunflower, soybean, and rapeseed with appropriate modifications. Please consult our team for dual-use configurations.

Capacity depends on your FFB supply and budget. A 1-5 TPH mill needs 20-120 tons of FFB per day and suits small plantations. A 5-30 TPH mill needs 120-720 tons/day for medium operations. A 30-100 TPH mill requires 720+ tons/day and is for large plantations. We recommend choosing a capacity that matches 70-80% of your available FFB supply to allow for seasonal variation.

Requirements vary by country and region. Most countries require environmental impact assessment (EIA) approval, business operation licenses, food safety certifications, and emissions/discharge permits. Our team can provide guidance on typical regulatory requirements for your region and help ensure your mill design meets local standards.

Yes, our modular equipment design supports future expansion. Many clients start with a 1-5 TPH mill and add capacity as their business grows. Key expansion steps include adding parallel press units, upgrading to larger sterilizers, and adding kernel recovery or refining lines. We design initial installations with expansion capability built in.

Yes, we provide complete turnkey project service from feasibility study and plant design to equipment manufacturing, installation, commissioning, and operator training. Our engineering team will visit your site to guide the entire project implementation.

All our equipment comes with a 12-month warranty from the date of commissioning. During the warranty period, we provide free repair and replacement for any quality-related issues. Extended warranty options are also available.

Installation time varies by project scale. Small scale mills (1-5 TPH) typically take 30-45 days, medium scale (5-30 TPH) takes 45-60 days, and large scale (30-100 TPH) takes 60-90 days. This includes equipment installation, testing, and commissioning.

Yes, we provide comprehensive operator training during the commissioning phase. Training covers equipment operation, daily maintenance, troubleshooting, and safety procedures. We also provide detailed operation manuals in English.
