Application scenario · Bobo-Dioulasso, Hauts-Bassins
One heat plant, three duties.
An established Hauts-Bassins mango dryer — receiving, ripening, peeling, slicing, drying and vacuum-packing for export. GreenMach’s proposed supply would replace the heat source, add drying capacity, and add a waste-to-feed line around the existing flow.
Design setpoint · 118 °C📍 Bobo-Dioulasso scenarioIllustrativeThe configuration at a glance
Panel rooms, central biomass plant, feed unit.
- Drying — 6 Rockwool panel rooms under a PEB steel shed
- Line batch — 4,968 kg fresh mango (≈497 kg dried)
- Heat plant — Central cashew-shell pyrolysis burner, 600,000 kcal/h
- Hot-air generator — Indirect double-chamber, three-pass — no gas contact
- Feed unit — Mango waste → pelletised feed, 5 t/day wet in
- Whole-line load — ~56 HP (vs 75.5 HP for a full-flow design)
Why replace the heat source
The incumbent burns banked LPG cylinders — imported, hard-currency fuel — to feed the existing dryers. GreenMach’s cashew-shell plant would displace that with a regional residue at ~4,800 kcal/kg, and the pyrolysis design handles the corrosive CNSL fraction that fouls equipment when shell is burned raw.
Three integrated duties
- Food drying — six independent panel rooms let batches be staggered rather than all moving together, at a tray-face temperature capped at 65 °C for EU-export dried mango.
- Waste valorisation — the same burner dries mango peel and trimmings for a pelletised livestock feed line running in the same season.
- Room to grow — the 600,000 kcal/h burner carries headroom for roughly two further chambers on the same plant (client cap 900,000 kcal/h).
A design note carried openly. The feed dryer and food line draw heat simultaneously — waste is generated while the chambers run — so the heat plant is sized for both together (about +200,000 kcal/h for the feed dryer). Figures are design-point and are confirmed against site survey and a real feedstock sample before manufacture.
Planning a mango line — food, feed or both?
We’ll scope the heat plant, the drying rooms and the waste line as one integrated supply.
