Garri is one of the most traded foods in the country, and demand is steady in every market from Onitsha and Aba to Ibadan and Kano. Mechanising even part of the process can raise output, improve quality and reduce the hard manual labour that traditional processing involves. This guide explains the main garri processing machines Nigeria processors use, what each one does and how to plan a setup that fits your budget and supply of cassava.
Whether you are a cooperative in Benue, a small processor in Ogun or an investor planning a factory in Edo, the stages are the same.
The garri production process in brief
Garri is made from fresh cassava roots in a sequence of steps:
- Peeling – removing the brown skin and inner peel
- Washing – cleaning off sand and dirt
- Grating – turning the roots into a wet mash
- Fermentation and pressing – bagging the mash, allowing it to ferment and pressing out the liquid
- Pulverising and sieving – breaking up the pressed cake and removing fibres
- Frying (garification) – roasting the meal into dry, crisp granules
- Cooling, sieving and grading – sorting by grain size
- Weighing and bagging – packing for sale
Fermentation and pressing help reduce the natural cyanogenic compounds in cassava, so these steps should not be rushed. Use fresh roots, ideally processed within a day or two of harvest, because roots deteriorate quickly once uprooted.
Key garri processing machines Nigeria processors use
Cassava peeling and washing machine
Manual peeling is slow and is often the biggest bottleneck. A cassava peeling and washing machine rated around 500 kg to 1 tonne per hour peels and washes in one step. Expect some trimming by hand for odd-shaped roots.
Cassava grater
The grater is the most common machine in garri processing. A cassava grater (grating machine) with a capacity of about 1 tonne per hour, powered by engine or electric motor, turns peeled roots into a fine, even mash. Even grating gives better fermentation and a more uniform final product.
Hydraulic or screw press
After fermentation, the mash in sacks is pressed to remove liquid. Hydraulic jacks or screw presses are faster and more consistent than heavy stones or logs.
Pulveriser and sifter
Pressed cake comes out in lumps. A pulveriser breaks it up and a sifter removes fibre and lumps before frying, giving a smoother finish.
Garri fryer
Traditional frying in wide pans over open fire is hot, smoky and labour-intensive. An automatic garri fryer of around 100 kg per hour stirs and roasts the meal continuously, giving more even colour and moisture and better working conditions. Many processors start by mechanising frying for that reason.
Weighing and bagging
Selling by weight protects your margin and your reputation. A heavy duty digital bench scale (300 kg) or a digital wireless platform scale (500 kg) is useful for weighing cassava deliveries and finished bags. Close bags neatly with a handheld bag closer sewing machine.
Planning your garri processing setup
Start from your cassava supply
Your machines should match the cassava you can reliably buy or harvest every day. A grater that can process a tonne per hour is wasted if you only receive a few hundred kilograms daily.
Find the bottleneck
In most small factories, peeling and frying are the slowest steps. Balance the line so no machine waits for another. For example, one grater may serve several fryers.
Power supply
Decide between diesel or petrol engines and electric motors. Engine-driven machines suit areas with unreliable grid power; electric machines are quieter and cheaper to run where power is stable.
Hygiene and water
Peeling and washing need plenty of clean water. Plan drainage for wastewater from washing and pressing, and keep frying areas clean and covered.
Staff and training
Machines change how people work. Train operators on safe use, especially around grater drums and fryer paddles, and agree simple cleaning routines at the end of each day. Clean machines last longer and produce garri that buyers trust.
Space and layout
Lay out the line in process order: receiving, peeling, grating, fermentation area, pressing, sieving, frying, cooling and bagging. Short distances between stages save labour.
What drives the cost of garri processing machines?
We do not publish prices in this guide, but the main cost factors are:
- Capacity of each machine (kg or tonnes per hour)
- Engine or electric drive
- Stainless steel or mild steel contact parts
- Whether you buy single machines or a complete line
- Delivery to your state and installation

Selling garri by weight
Many garri sellers still use paint buckets or "mudu" measures, which vary from market to market. Weighing every bag lets you price fairly, track yield from roots to garri and spot losses. Kira Scales supplies platform, floor and bench scales and provides calibration so your scales stay accurate. If you buy cassava by the truckload, a weighbridge at your gate records every delivery.

Frequently Asked Questions
What machines do I need to start a garri processing business?
The core machines are a cassava grater, a press and a fryer, plus scales for weighing. Larger operations add a peeling and washing machine, pulveriser, sifter and bag closer.
How much cassava makes one bag of garri?
Yield varies with cassava variety, root age and processing method, so measure it yourself by weighing roots in and garri out. Weighing both ends of the process is the reliable way to track yield.
Is an automatic garri fryer better than manual frying?
An automatic fryer gives more even roasting, steadier output and far better working conditions than open-pan frying. Many processors mechanise frying first for that reason.
Can garri machines run without electricity?
Yes. Graters and some other machines are available with petrol or diesel engines, which suits rural areas with unreliable power.
How long should cassava mash ferment before frying?
Processors commonly ferment for one to several days depending on the sourness they want. Proper fermentation and pressing also help reduce natural cyanogenic compounds in cassava.
