Nigeria grows more cassava than almost any other country, yet a large share is still processed by hand in small batches. A well-planned cassava processing line setup turns fresh roots into garri, fufu, high-quality cassava flour (HQCF) or starch at a steady, predictable rate. A poorly planned one leaves expensive machines idle while workers queue at a single slow step.
This guide is for investors, cooperatives and existing processors in states such as Oyo, Ogun, Benue, Cross River, Edo and Enugu who want to move from scattered machines to an organised line.
Step 1: Decide what you will produce
Your end product shapes the whole line.
- Garri: peeling, washing, grating, fermentation, pressing, sieving, frying, grading and bagging.
- Fufu / akpu: peeling, soaking or fermenting, grating or milling, sieving and pressing, often sold wet.
- High-quality cassava flour: peeling, washing, grating, pressing, fast drying, milling, sieving and packing. HQCF is unfermented and must be dried quickly.
- Starch: grating, extraction with water, settling, dewatering and drying, which needs much more water and specialised equipment.
Many small and medium factories start with garri, then add flour once they have steady root supply and buyers. If garri is your focus, see our separate guide to garri processing machines in Nigeria for detail on each machine.
Step 2: Size the line to your root supply
Fresh cassava roots begin to deteriorate soon after harvest, so a line must process roots quickly. Start with:
- How many tonnes of fresh roots you can reliably receive per day, from your own farm or outgrowers
- How many hours per day you will run
- Seasonal changes in supply and root quality
Then size each machine so the line keeps pace. For example, a cassava peeling and washing machine rated around 500 kg to 1 tonne per hour, feeding a cassava grater of around 1 tonne per hour, is a balanced front end for a small factory.
Step 3: Find and fix the bottleneck
Every line has a slowest step. In cassava processing it is usually one of these:
- Peeling: manual peeling is slow; mechanical peelers help but still need hand finishing.
- Pressing: mash must sit and drain, so you need enough presses and space.
- Frying or drying: frying garri or drying flour takes time and heat. Adding an automatic garri fryer or more dryer capacity often lifts output more than any other change.
Balance the line so each stage can handle the output of the stage before it.
Cassava processing line setup: layout principles
A good layout saves labour and keeps the product clean:
- Receiving and weighing area near the gate, where roots are weighed and checked.
- Wet section: peeling, washing and grating, with good drainage and a concrete floor that slopes to drains.
- Fermentation and pressing area: covered, ventilated and with space for sacks or tanks.
- Dry section: frying or drying, sieving and milling, kept separate from wet areas to avoid contamination.
- Packing and storage: clean, dry, raised off the floor and protected from pests.
Keep material moving in one direction, from raw to finished, without crossing back.
Utilities: water, power and wastewater
- Water: washing roots and starch extraction use a lot of water. A borehole and overhead tank are common.
- Power: decide which machines will run on grid power, generators or engines. Group electric loads so your generator is sized correctly.
- Heat: fryers and dryers need firewood, gas or other fuel. Plan fuel storage and ventilation.
- Wastewater and peels: cassava wastewater should not run into streams. Plan soak-away pits or treatment, and consider using peels as livestock feed after proper processing.
Weighing: the control system of your factory
Weighing tells you whether the factory is making money. Weigh at three points:
- Intake: weigh every delivery of roots. Small deliveries can go on a 5 tonne platform scale or a heavy-duty floor scale. If roots arrive by truck, a weighbridge records full and empty weights for every vehicle.
- In process: spot-check yields at key steps to find losses.
- Output: weigh finished bags before sale so every bag is consistent.
Comparing intake weight with finished product weight gives your yield. Tracking it daily shows when root quality drops or when a machine needs attention. Kira Scales has supplied weighing equipment to agro-processing plants and offers calibration to keep scales accurate.
What drives the cost of a cassava processing line?
We do not publish prices in this article. The main cost drivers are:
- End product (garri lines differ from flour or starch lines)
- Daily capacity and number of machines
- Engine or electric drive, and generator size
- Stainless steel for food-contact parts
- Building, drainage, water supply and wastewater handling
- Weighing equipment, from platform scales to a weighbridge
See each product page for current pricing or request a quote with your daily root volume and target product.
Common mistakes to avoid
- Buying a large grater before securing steady root supply
- Ignoring the frying or drying bottleneck
- Mixing wet and dry sections in one space
- No plan for wastewater and peels
- Selling by measure instead of weight

Frequently Asked Questions
What machines are needed for a cassava processing plant?
A typical garri line needs a peeler and washer, grater, press, pulveriser or sifter, fryer and scales. Flour lines replace the fryer with a dryer and add a mill and sieve.
How much cassava can a small processing line handle?
It depends on your machines and working hours. A front end built around a peeler and a grater rated near 1 tonne per hour suits many small factories.
What is the most common bottleneck in cassava processing?
Peeling, pressing and frying or drying are the usual bottlenecks. Adding capacity at the slowest step lifts output more than upgrading other machines.
How do I calculate cassava processing yield?
Weigh roots at intake and weigh finished product at the end. The ratio between them is your yield, and tracking it daily shows when root quality or processing changes.
Do I need a weighbridge for a cassava factory?
If roots arrive by the truckload, a weighbridge records the net weight of every delivery and supports fair payment to suppliers. Smaller sites can use platform or floor scales.
