Shea drying systems in Ghana
What the crop demands, what the country imposes, and what that means for capacity.
Northern Ghana’s shea belt is well organised relative to the region, with strong women’s cooperatives and established links to international cosmetics buyers. That organisation makes quality improvements stick — a cooperative that can hold a moisture specification can negotiate on it, which is not true where collection is atomised.
The situation in Ghana
Better roads, better power and a deeper domestic market than most of its neighbours, and Tema is one of the region’s best-run ports. The constraint here is rarely logistics and usually raw material consistency: Ghana exports a great deal of semi-processed product that loses value because grading and moisture control are done by eye at the point where they should be measured.

What shea kernel drying demands
Shea is collected, not farmed, which makes moisture the whole quality problem: nuts come in wet from the bush at the height of the rains and are traditionally dried on the ground. Free fatty acid rises with every day the kernel sits damp, and FFA is precisely what the butter buyer pays on. Controlled drying to 6–8 % is the difference between industrial grade and cosmetic grade.
Harvest calendar

Market and buyer requirements
Cosmetics and food butter buyers in Europe and North America, several with long-standing direct relationships with Ghanaian cooperatives. Fair-trade and organic premiums here are real and depend on documented handling.

Frequently asked questions
Why does cooperative organisation matter for drying?
Because a cooperative that can hold kernels to 6–8 % moisture across every member’s delivery can sell on that specification and price on it. Where collection is atomised, the same equipment cannot fix a lot that arrives already above 3 % free fatty acid.
Does drying affect the shea premium directly?
Yes, through free fatty acid. FFA rises with every day the kernel stays damp, and cosmetic grade sits below about 3 %. Drying promptly at 50–60 °C over 12 to 20 hours is the main lever a collector has over the number they are paid on.
What scale suits a Ghanaian shea cooperative?
5 t/day of fresh nut produces roughly 1.7 tonnes of dried kernel daily at about 3 : 1, on a 12 to 20 hour cycle at 50–60 °C. That is around 170 tonnes across the June-to-September season — a serious direct-export volume for a single cooperative union.
