Biomass heating for snack frying and edible oil systems
The oil is the product, not just the medium.
A biomass burner heats frying oil indirectly, through a heat exchanger, so combustion products never enter the oil. SahelDry burners are rated 200,000 to 900,000 kcal/h with PLC-controlled staged combustion, firing pellets, briquettes or crop residue in place of diesel and LPG on continuous snack fryers and batch frying lines.
Indicative price of a biomass hot air generator, Ex-Works (EXW): USD 3,140–14,135
Shipping, customs clearance and local duties are extra. The final price depends on the configuration and is fixed in the written quotation.
How the heat reaches the oil
Frying oil degrades with heat history. Local overheating at the exchanger surface accelerates polymerisation and shortens oil life, which is a direct running cost, not just a quality question. Indirect transfer with controlled surface temperature is therefore an economic argument as much as a food-safety one.
Typical applications
- Continuous namkeen and savoury snack fryers
- Batch frying pans and kettle systems
- Chips and crisps lines
- Post-fry de-oiling and drying — this stage is a hot air duty rather than an oil duty
Specifications
| Parameter | Value |

| Burner capacity | 200,000–900,000 kcal/h |
| Fuels | Pellets, 90 × 90 mm briquettes, cashew shell, crop residue |

| Lead time | 10–18 weeks from confirmed order and receipt of advance payment |
The post-fry de-oiling and drying stage is an air duty — see the biomass hot air generator. For the fuel stage see the biomass pellet burner. The nearest sibling duty is bakery oven heating.
Supply outside West Africa
We accept orders from any country. West Africa is the market these systems are engineered around and where most of them go, but there is no territory we will not supply.
Lead time, warranty and scope of supply do not change with the destination: manufacture in 10–18 weeks from confirmed order and receipt of advance payment, warranty 12 months from date of shipment, and spares dispatched alongside the machines. For installation outside the region the buyer covers the team’s travel, accommodation and entry formalities — stated up front because it is a real line in the budget. Documentation and the operator interface are supplied in English and French; other languages on request.
Frequently asked questions
Will biomass firing affect oil quality?
Not if the transfer is indirect and surface temperature is controlled. Combustion products never contact the oil. What affects oil life is heat history — local hot spots at the exchanger surface — so exchanger area and circulation are specified against your oil volume and turnover rate rather than against burner size alone, holding the oil steady between 160 and 200 °C.
Can it hold frying temperature during continuous production?
The thermic fluid loop is what carries the load, and it behaves well under continuous frying precisely because the fluid is a buffer: the fire does not see the product, the loop does. Recovery after a cold load drop depends on loop volume and exchanger area rather than on burner rating alone, which is why we size the loop against your worst-case drop rate — continuous frying at 160–200 °C, not the average — and confirm it at commissioning.
What fuel volume should I plan for?
Fuel consumption follows heat demand, which follows oil volume, throughput and how much moisture the product carries in. We calculate it from your line data at sizing, somewhere inside the 200,000 to 900,000 kcal/h range, rather than quoting a figure that would not survive contact with your process.
