We turn cashew shells — an abundant West-African waste stream — into clean, low-cost heat for industrial food drying. Consistent quality, dramatically lower fuel bills, and a smaller carbon footprint.
Design outlet · 182 °CDiesel, gas and open-fire drying are expensive, dirty and inconsistent. Our cashew-shell burners give processors clean, controllable heat — and turn a local waste product into value.
Cashew shells cost a fraction of diesel or LPG per kilocalorie. Most processors recover the burner investment within a single season.
Closed-loop PLC control holds drying temperature to setpoint, so every tray comes out uniform — no scorching, no under-dried spoilage.
Carbon-neutral biomass plus MERV-8 filtration keeps smoke off your product and cuts emissions versus fossil-fuel dryers.
Cashew processing byproduct becomes your energy source — a circular supply chain that keeps money in the local economy.
Stainless heat exchangers and refractory-lined combustion chambers designed for continuous, multi-shift seasonal duty.
Spare parts, training and field engineers based in-region — not an ocean away — so downtime stays measured in hours.
From a single batch chamber to an integrated tunnel line, every system is built around the same reliable cashew-shell combustion core.
Purpose-built to burn cashew nut shells cleanly and efficiently — our most popular unit for West-African processors.
Runs on briquetted mango peel, rice stalk, corn cob, groundnut and cotton residue — ideal where cashew shell is seasonal.
Indirect heat exchangers deliver clean, contamination-free hot air straight into your dryer for food-grade contact.
Continuous-flow tunnels for high-volume mango and vegetable operations that never stop during harvest peak.
Cabinet and room dryers sized for cooperatives and growing SMEs — start small, scale as demand grows.

West Africa processes millions of tonnes of cashews every year — and the shells are usually a disposal headache. We turn that byproduct into a dense, high-calorie fuel that burns hotter and cleaner than firewood.

See fuel-cost comparisonCashew shells are rich in CNSL, a corrosive oil that makes them smoke, foul and corrode an ordinary furnace when burned raw. Pyrolysis solves that. Instead of setting the shell alight directly, we first heat it in a low-oxygen chamber so it breaks down into a clean combustible gas — then burn that gas in a second stage: hot, complete and smoke-free. The heat is passed to your product indirectly, so combustion never touches the food.
The shell is turned to gas first, then burned hot and complete — none of the black smoulder you get burning oily shell raw.
Two-stage combustion releases far more of the shell’s energy, so you burn less to dry the same tonnage.
The 15–25% cashew-shell oil that clogs and corrodes ordinary burners is handled by design, not fought against.
The process leaves a useful carbon by-product — one more stream of value from the same waste.
Precise, hygienic hot air adapts to fruit, fish, grain and beyond — protecting colour, nutrition and market value.
🥭Our founding application. 65–70 °C, 16–20 h, 12–14% final moisture for export-grade dried mango.
Primary focus
🐟Hygienic 45–50 °C drying with managed humidity — consistent, documented, batch after batch.
High demand
🥬Pineapple, banana, tomato, chilli, ginger and onion — flexible temperature profiles for every crop.
Versatile
🌾Cereals, cocoa, coffee, cassava, spices and botanicals — reliable industrial-scale moisture control.
Year-roundThe full journey a mango operation runs every season — from a mountain of fresh mango to sealed, export-grade product on the shelf.
Cashew shells (or other biomass) are auto-fed into the refractory-lined combustion chamber.
A two-stage burn maximises energy release while a heat exchanger keeps combustion gases away from your food.
Filtered hot air circulates through the dryer at a PLC-controlled temperature and airflow.
Uniform, export-grade product comes out — with fuel costs and emissions a fraction of fossil-fuel drying.
We design for the realities of the region: variable power, seasonal harvests and the need for parts and expertise close by. Every supply is structured around in-region spares access and hands-on operator training — built into the scope, not bolted on afterwards.

Every line we quote is engineered in full first — sized to your harvest, your fuel and your buyers — and delivered with operator training and in-region spares. Judge us on the depth of the design, not on a wall of logos.”
