Commercial Groundnut & Sesame Oil Production in Nigeria

Starting a commercial groundnut & sesame oil production in Nigeria facility is one of the most practical manufacturing ventures in the agro-processing sector. Both groundnuts (peanuts) and sesame seeds (beniseed) are widely produced across major agrarian regions, and local market demand for pure, unadulterated edible oils remains consistently high throughout the year.

However, the primary operational challenge for new and expanding processors is selecting the correct machinery capacity.

Installing an undersized expeller limits your ability to fulfill bulk wholesale contracts, while buying an oversized industrial line before establishing steady feedstock supply chains ties up critical working capital.

Matching your operational capacity with local raw material availability is essential to running a profitable plant. Below is a practical guide to sizing an edible oil processing facility using commercial spiral expellers.

1. Raw Material Yields: Groundnuts vs. Sesame Seeds

Before choosing your machine capacity, you must calculate expected output based on seed extraction characteristics. Both groundnuts and sesame seeds are considered high-yield oilseeds:

• Groundnuts (Peanuts): Groundnuts deliver an oil yield of 40% to 50% of their total seed weight through mechanical pressing. A standard 50 kg sack of clean, shelled groundnuts yields approximately 20 to 25 liters of virgin oil, alongside high-protein seed cake that is sold as livestock feed or processed into food products.
• Sesame Seeds (Beniseed): Sesame seeds average an extraction yield of 45% to 55% oil by weight. Sesame oil commands a higher wholesale price than standard cooking oils due to strong culinary, pharmaceutical, and export demand.

2. Choosing the Right Capacity: The GD Series Sizing Scale

Commercial spiral oil expellers—such as the BrandSquare GD Series, utilize a high-strength alloy steel screw mechanism to continuously compress oilseeds through a heated pressing barrel.

Each model features an integrated vacuum filtration system with dual filter tanks, which draw raw crude oil through fine filter cloth using vacuum suction. This delivers clear, clarified oil straight from the machine without needing settling tanks.

Here is how machine models align with different processing scales:

Machine Model	Processing Capacity	Main Motor Power	Power Supply Specification	Target Processing Scale
GD-60	30 – 40 kg / hour	2.2 kW	220V Single-Phase or 380V Three-Phase	Small farms, homesteads, and artisanal oil brands
GD-70	60 – 70 kg / hour	3.0 kW	220V Two-Phase or 380V Three-Phase	Growing small enterprises processing 10 to 12 sacks per shift
GD-100	200 – 250 kg / hour	7.5 kW	380V Three-Phase (Industrial Connection)	Mid-scale packaging facilities supplying wholesale markets
GD-125	300 – 400 kg / hour	15.0 kW	380V Three-Phase (Industrial Connection)	Medium commercial mills handling multiple tons per week
GD-500	450 – 500 kg / hour	30.0 kW	380V Three-Phase (Industrial Connection)	High-volume industrial plants serving institutional buyers

3. Operational Requirements for Nigerian Facilities

Sizing your equipment properly also means preparing your facility to support the machine’s technical requirements:

Electrical Infrastructure

The GD-60 can operate on standard 220V power. However, commercial units from the GD-100 through the GD-500 require a dedicated 380V three-phase electrical supply or a suitably sized commercial diesel generator to maintain continuous operation during grid outages.

Digital Temperature Management

Different seeds require specific temperatures to release oil cleanly. Groundnuts extract efficiently under moderate chamber heat, while harder seeds like sesame benefit from controlled pre-heating. The GD Series uses a digital control panel with automatic temperature regulation to keep the pressing chamber at the target temperature without burning the product.

Moisture Control and Seed Preparation

For both groundnuts and sesame, seed moisture content should remain between 6% and 9%. Seeds with excessive moisture produce a thick paste that clogs the pressing barrel, while overly dry seeds create excessive friction. Sun-drying or light roasting before loading into the feed hopper ensures smooth operation and consistent oil flow.

The Takeaway

Achieving strong margins in commercial groundnut & sesame oil production in Nigeria depends on choosing equipment that matches your feedstock supply and local distribution capacity. Starting with an appropriately sized spiral expeller ensures high equipment utilization and steady cash flow, allowing your business to expand sustainably as processing volumes grow.
