Roasting on Wood, Gas or Electric
Three burner modules fit one drum body: a wood-fired grate base, a gas burner base, an electric base. Swapping fuel means changing the base, not the machine.
The drive motor draws only 0.75 kW. A small generator carries it, so roasting continues through blackouts - the reason groundnut oil mill roasters in West Africa and South Asia run on wood and groundnut shells instead of electricity.
Fuel from your own farm waste - groundnut shells, maize cobs, wood offcuts - costs collection labor and nothing else. Electric heating pays the grid for every kilojoule; wood heat pays the farmyard.
Groundnut and Oil Seed Mill Applications
Groundnut oil pressing starts with roasting: kernels into the drum, 30-40 minutes of rolling heat, out to the press with higher oil yield and the aroma buyers pay for. The same drum runs sunflower seed, soybean and sesame batches - this is the oil seeds roaster machine stage that sits ahead of every screw press in the region.
Snack workshops roast groundnut and sunflower seed for packing. Cashew processors run the cashew nut roaster supplier configuration with adjusted drum speed. One machine, three businesses: oil mill preprocessing, snack roasting, and grain drying.
How the Drum Roasts Without a Boiler
A firebox under the drum heats the shell; conduction and radiation push heat through the steel wall while the drum rotates the bed continuously. Every kernel rolls through the hot zone instead of sitting on one hot spot.
When the batch finishes, the drum reverses and the roast discharges through the outlet. Reload, reverse the airflow, start the next batch.
The firebox is a module. Wood grate for farm waste, gas ring for bottled gas, electric elements where power is cheap - the drum stays on its frame.
Built From Heavy Steel Plate
Frame and drum shell: 4-8mm steel plate, welded, sized for continuous outdoor duty. Thin-sheet roasters deform in their first season; this one carries its 230 kg frame through years of it.

Daily Operation
Sieve stones out before the drum - a stone in the drum rings the shell.
One batch at a time: roast, discharge, reload. Stacked batches sweat back moisture.
Burn farm waste: groundnut shells and maize cobs from the same harvest that produced the kernels.
Reverse the drum per the manual sequence; never switch rotation under load.
Warranty, Certification and Custom Builds
Twelve-month warranty on the machine. Mechanical test report and factory video inspection ship with every unit - you see the run before you pay the balance.
Custom builds cover drawings, samples, OEM and ODM branding, and the burner module of your choice. The unit is SGS-certified and ships from Henan in the packing box listed above.
Frequently Asked Questions
Q: Can this commercial peanut roaster machine run during a blackout?
Yes. Heating runs on wood or gas, independent of the grid. The drum drive draws only 0.75 kW, which a small generator covers easily - the standard setup for mills in unstable-power regions.
Q: Is wood heat cheaper than electric?
The fuel bill says so. Wood, groundnut shells and maize cobs from your own harvest cost collection labor; electric elements cost the grid per kilowatt-hour, every hour. Over a season the difference compounds.
Q: How do the fuel modules swap?
The burner base is a module: grate for wood, ring for gas, elements for electric. Unbolt one base, bolt on the next - the drum body stays on its frame.
Q: What can it roast?
Groundnut for oil pressing, sunflower seed, soybean and sesame for milling, plus snack-grade roasting - the oil seeds roaster machine duty that sits ahead of every screw press.
Q: What is the daily output?
The LL-100 holds 100 kg/h; an eight-hour day moves 800 kg. The series tops out at 600 kg/h for plants that grow past it.
Q: How thick is the steel?
4-8mm plate on frame and drum shell, welded for continuous duty. Thin-sheet roasters deform in their first season; this one does not.
Q: What certification ships with it?
Mechanical test report and factory video inspection with every unit, SGS-certified manufacturer, 12-month warranty, OEM/ODM accepted from drawings or samples.
