1. What is the standard processing line for a PKO plant?

A complete processing line transforms hard palm kernels into clear, valuable oil. The key stages and their functions are as follows:

Stage Equipment Purpose
Preparation Fiber Separator, Cracker & Shell Separator Removes fiber from the nut, then cracks it to separate the shell from the inner kernel
Size Reduction Crusher Crushes the clean kernel into smaller, uniform pieces to improve pressing efficiency
Conditioning Cooker/Roaster Adjusts the moisture and temperature of the crushed kernel to optimize oil yield during pressing
Extraction Screw Oil Expeller/Press Applies mechanical pressure to extract crude oil from the prepared kernel material
Clarification Plate & Frame Filter Removes solid impurities from the crude oil, resulting in a clearer, higher-quality product

The entire line is designed for continuous, stable operation to achieve high oil extraction rates.

2. What scale of plant is right for me? (Small vs. Large)

The scale of your plant is a critical decision that depends on your investment capital and production goals.

Scale Type Daily Capacity Typical Setup & Technology Best Suited For
Small/Minor Up to 5 tons/day A single screw press or a basic assembly unit. Often used for raw, pre-shelled kernels New investors, low-budget startups, or entry-level production
Medium 5 – 20 tons/day A complete mechanical pressing line with a capacity of 0.5 – 2 tons per hour Family businesses or cooperatives looking for consistent, quality output
Large 50+ tons/day Full industrial-scale plant that may use mechanical pressing or solvent extraction to maximize oil recovery Industrial players with significant capital and large-scale output goals

For many Nigerian entrepreneurs starting out, a small to medium-scale mechanical pressing line is the most practical entry point.

3. How much does a PKO processing plant cost in Nigeria?

The investment required is highly variable and depends on capacity and automation. Here are some recent cost benchmarks for equipment alone:

Plant Capacity Estimated Equipment Cost (USD) Notes
10 tons/day (TPD) $60,000 For a complete palm kernel oil production line

It’s crucial to treat these as equipment-only estimates. The total investment will be significantly higher after accounting for shipping, import duties, installation, land, infrastructure, and working capital. For context, a community-based oil mill project costing ₦10,500,000 was estimated, which included ₦5,000,000 for the acquisition of machines.

4. What is the latest technology available for PKO extraction?

Innovations are helping Nigerian processors become more efficient. Locally developed machines are making a difference:

  • Efficient Cold-Pressing: A team from LAUTECH has designed a palm kernel oil extraction machine that processes cold seeds without pre-treatment. Driven by a 10hp motor, it has a capacity of 100 kg per hour and achieves an 87.10% oil extraction efficiency. A key feature is its adjustable choke mechanism, which controls back pressure to maximize oil yield and manage the thickness of the pressed cake.
5. How do I choose a reliable supplier and ensure support?
  • Look for Nigerian Experience: Choose suppliers who can demonstrate successful projects in Nigeria. For example, one 5 TPD plant was successfully installed and integrated with a client’s existing 2 tons/hour palm oil mill in July 2025.
  • Plan for Spare Parts: Ensure your supplier can guarantee the availability of spare parts. A well-managed customer secured a 6 TPD assembly unit and also purchased spare parts like pressing rings, worms, and filtering cloth from the start to avoid future downtime.
  • Consider Local Support: Suppliers with local branches or service centers are crucial for prompt assistance and maintenance.
