Continuous charcoal kiln BIO-KILN

The BIO-KILN carbonization furnace is a patented, environmentally friendly, continuous installation for the thermal processing of plant materials. It is designed specifically for the production of high-quality charcoal as a raw material for the production of hookah charcoal, charcoal briquettes, activated carbon or bio-char.


Raw materials: shells and pits of nuts and fruits, wood chips, wastes of woody shrubs, seeds, bamboo and other raw materials of plant origin. The fraction should be between 5 and 40 mm in size and contain moisture not more than 20% by weight.

Products: charcoal obtained from fruit pits and nutshells is used to produce activated carbon, briquetted forms for BBQ or for hookahs. BIO-Char, intended as a soil enhancer or hydroponic growth enhancer for the agricultural industry, is made from plant materials and contains no harmful substances.

The main advantage of BIO-KILN: constant quality parameters and output volumes of the product are readily achieved, since charcoal production occurs without human intervention in the technical process.

The benefits of this charcoal production plant include:

  • Reliability of the kiln. The carbonization device is made 100% from refractory materials.
  • Environmental Safety
  • High efficiency from a compact device
  • High productivity: 30-120 t / month, depending on the raw materials and the kiln model (Bio-Kiln 1, 2 or 3)
  • Continuous production process
  • Minimal staff intervention in the production process
  • Production of thermal energy, which can be used for drying of raw materials, drying of charcoal briquettes, or other heating purposes
  • Low power consumption (0.01kW) provides kiln autonomy
  • Remote Control Capability
  • Full process automation
  • Non-volatile carbon content in charcoal from 75% to 95%

Ancillary equipment



The kiln can also be equipped with

  • Heat exchanger: equipped with gas and water equipment for heating water or other process fluid; gas-to-air installation – for supplying air at high temperature.
  • Pre-drying of raw materials: chamber, tunnel or drum type. To ensure the preparation of raw materials – moisture removal, prior to the carbonation process.

Operating the Bio-Kiln

Chopped (5-40 mm) and pre-dried raw materials (moisture <20%) are loaded into the storage hopper with vibrating feeder, from where using the bucket elevator is loaded into the kiln hopper.

Loading raw materials into the hopper the furnace is made as the finished charcoal is unloaded and level sensor signals in it. Raw materials come from the storage hopper of the kiln into the carbonization device, which is vertical shafts-channels for raw materials and heat carrier, in this case, the raw material moves from top to bottom, and the coolant in opposite direction.

Raw material channels end at the bottom with gateway devices for unloading charcoal into a stabilization hopper. As unloading of finished charcoal, raw material moves down the channels, while in the carbonization device the following processes take place:
preheating, pyrolysis and charcoal calcination.
Processes: stabilization and cooling of charcoal, take place in stabilization hopper of the furnace, from where using the auger is unloaded into the storage hopper of finished charcoal, the charcoal passes through the air stabilization, after which the charcoal is ready for further use.
The flue gases, after the carbonation device, enter the afterburner, where they are completely burned – decomposition, ensuring 100% environmental friendliness of the furnace – no harmful emissions into the atmosphere.

Exhaust flue gas temperature after the afterburner of the furnace is more than 1000 ° C, which makes it possible to use them for various thermal processes: preliminary drying of raw materials, heating of premises, briquette drying, steam superheating for activation, etc.

After going through all stages of processing, the finished coal is unloaded into the trolley, which, as it is filled, is replaced by an empty trolley.

The discharged product is then sent to packaging or to the line for the production of briquettes for hookah and barbecue, where it is initially crushed, mixed with water and passed through an extruder to form briquettes of a given shape.
