Plantain drying systems in Cameroon
What the crop demands, what the country imposes, and what that means for capacity.
Plantain is a staple across southern Cameroon and one of the most wasted crops in the country: bunches ripen together, urban prices swing wildly through the year, and fruit that is too ripe or too far from a road is simply lost. Plantain flour is a growing urban product and the obvious destination for all of it.
The situation in Cameroon
Often described as Africa in miniature, and for processing purposes that is literally true: rainforest, highland and Sahel inside one set of borders, with harvests that therefore never all happen at once. A chamber in the Littoral can work cocoa, pepper and plantain across a calendar that has no real off-season, which changes the utilisation arithmetic completely.
Growing regions. the Littoral and South-West for cocoa and pepper, the West highlands for coffee and horticulture
What plantain drying demands
Plantain flour is a growing urban product and a natural outlet for fruit that is too ripe, too small or too far from market to sell fresh. Sliced at 4–6 mm and dried to 10–12 %, a crop with a one-week window becomes a milled product with a one-year one.
Harvest calendar
Year-round, with peaks that vary by region rather than a single national season. Continuous availability, which suits a chamber well.
The working campaign window as the trade runs it. It shifts a fortnight either way with the rains.

Market and buyer requirements
Domestic urban demand for plantain flour, which is growing quickly in Douala and Yaoundé, plus a diaspora export market for a product that is currently hard to buy in consistent quality.

Frequently asked questions
Why is plantain so wasted?
Because bunches ripen together and the fresh window is about a week. Fruit that is too ripe, too small or too far from a road has no outlet at all — dried at 3 : 1 to 10–12 % moisture it becomes a milled product with a twelve-month life.
What thickness suits plantain?
4–6 mm slices at 60–65 °C over a 10 to 14 hour cycle. Thicker slices case-harden on a starchy fruit, and the resulting flour mills unevenly — the same failure mode as mango, on a crop that is far less forgiving of it.
Is there really a market for plantain flour?
A growing one in Douala and Yaoundé, and a diaspora market abroad that struggles to buy it in consistent quality. A 10 t/day line producing about 3.3 tonnes daily is sized for the urban trade rather than for export alone.
