Tomato drying systems in Nigeria
What the crop demands, what the country imposes, and what that means for capacity.
Nigeria loses an enormous share of its tomato crop between field and market — the standard figure quoted in the sector is around half — while simultaneously being one of the world’s largest importers of tomato concentrate. The two facts sit next to each other every year and the gap between them is a drying problem.
The situation in Nigeria
The domestic market is the story. Two hundred million consumers mean a processor can build a serious business without ever exporting, which changes the specification: buyers want volume, price and consistency rather than EU documentation. Power is the binding constraint almost everywhere, and a heat source that does not depend on the grid is not a sustainability choice here but an operational one.
Growing regions. Kano, Kaduna and Kebbi in the north, Oyo and Ogun in the south-west, the Niger delta
What tomato drying demands
Tomato has the harshest yield ratio of any crop on this site: fourteen tonnes of fresh fruit for one tonne dried. That makes intake logistics, not drying, the binding constraint — and it also means a glut that would otherwise rot in the field is exactly the raw material this process wants.
Harvest calendar
February to April in the northern producing states around Kano and Kaduna, with a second smaller window in November and December. The February-to-April glut is when roadside prices collapse.
The working campaign window as the trade runs it. It shifts a fortnight either way with the rains.
Process parameters
| Parameter | Value |
|---|---|
| Drying temperature | 55–62 °C |
| Final moisture | 10–14 % |
| Yield (fresh : dried) | 14 : 1 |
| Cycle time | 18–26 h |

Fuel available in Nigeria
Palm kernel shell in the south-east, rice husk in Kebbi and the north, and an unmatched cassava peel resource — wash it before use.

Market and buyer requirements
Domestic, substituting directly for imported concentrate and supplying the sauce, restaurant and food-processing trade. This is import substitution at national scale rather than an export play.
Frequently asked questions
Why does Nigeria import concentrate while losing its own crop?
Because the crop and the demand are separated in time and the product cannot bridge the gap. Roughly half is lost between field and market; dried at 14 : 1 to 10–14 % moisture, the February-to-April glut becomes a stable product that supplies the rest of the year.
Is 20 t/day large for tomato?
It is mid-size, and it produces only about 1.4 tonnes of dried product a day — tomato has the harshest ratio of any crop here. Intake handling, not chamber capacity, is what has to be designed for on this crop.
Why dry rather than build a paste plant?
Capital and cold chain. Paste needs sterile filling, canning and distribution infrastructure; dried tomato at 55–62 °C over an 18 to 26 hour cycle needs none of it and is stable at ambient temperature — a far lower entry point into the same demand.
