Machines builtto never stop.
The OLT-D continuous carbonization machine is the main equipment for biochar production: PLC-controlled end to end, heated by its own pyrolysis gas once running, and designed for months of continuous duty.

Every drawing here is one of Olten's catalogue machines, running. Together they make a complete charcoal line.
01
Crush
02
Dry
-
01Crush and dry
Feed must be ≤ 15 % moisture and ≤ 30 mm. Material that doesn't meet this is crushed and dried first.
-
02Preheat to 350–400 °C
The drum is heated by natural gas, diesel or LPG through the heating nozzle before any material enters.
-
03Feed and carbonize
A sealed hopper with a limit sensor and screw feeder keeps the drum airtight while biomass turns through it.
-
04Gas takes over
About 20 minutes after feeding, combustible gas forms. The induced-draft fan leads it to the combustion chamber, which heats the drum and cuts energy use.
-
05Reuse the heat
Part of the waste-heat flue gas dries incoming feed; the rest can fire a boiler. Exhaust leaves through dust removal and flue-gas treatment.
Feed must be ≤ 15 % moisture and ≤ 30 mm. The drum is heated to 350–400 °C before feeding; about 20 minutes after feeding starts, combustible gas forms and the induced-draft fan returns it to the combustion chamber, which then heats the drum.

Mold
Why it runs for months
Fourteen systems, engineered as one.
-
01
Feeding
U-type, tube or large-inclination belt feeders, chosen for the material and site.
-
02
Airtight inlet
Hopper with a limit sensor keeps the drum sealed.
-
03
Main drum
304 stainless steel for heat and corrosion; other grades on request.
-
04
Insulation
Ceramic-fibre modules: dense, heat-resistant, no shrinkage.
-
05
Discharge
Water-cooled discharge conveyor: good cooling, low cost.
-
06
Induced draft
304 stainless impeller with a special seal: no leakage.
-
07
Heating
Direct heating with natural gas, diesel or LPG, PLC temperature control.
-
08
Transmission
Inner-cylinder drive keeps the gear ring and riding rings away from heat.
-
09
Combustion chamber
Cast high-alumina refractory for long high-temperature service.
-
10
Temperature monitoring
Integrated PLC with automatic control.
-
11
Sealing
Four dynamic seals on the drum, each with an 8-layer structure.
-
12
Purification
Full combustion in the chamber, exhaust treated before discharge.
-
13
PLC control
Manual and automatic modes; feed rate, drum speed, fan frequency, temperature and remote assistance.
-
14
Modular build
Dual support of host and chassis for fast installation and commissioning.
