Secador preliminar para los hornos de carbón del modelo EKKO
Used to “quickly and efficiently” remove moisture from wood to obtain dry raw materials for pyrolysis. Pre-dryer is used to remove moisture from wood quickly and efficiently in dryer devices, to produce dry raw materials for pyrolysis. Pre-dryer takes place outside the drying / pyrolysis chamber, which can significantly reduce the cycle time and increase the kiln productivity from 50 to 100%, using fresh wood.
Preliminary dryer is used to “quickly and efficiently” remove moisture from wood to obtain dry raw materials for pyrolysis. Preliminary drying takes place outside of the drying/pyrolysis chamber, which can significantly shorten the cycle time and increase the productivity of the kiln from 50 to 100% when using “fresh” wood.
Preliminary drying of raw materials can be carried out either in trolleys for EKKO, or in a separate chamber of continuous or periodic operation for Bio-kiln. The use of a chamber or a drying drum for preliminary drying significantly increases the efficiency of the process, due to the special design of the chamber, which provides minimal heat loss and the most effective contact of the heat carrier with the raw material.
Options for devices for preliminary drying of raw materials:
- Chamber drying (batch type)
- Continuous Tunnel Drying
- Continuous shaft drying
- Continuous Drum Drying
- Trolleys for GreenPower EURO and EKKO kilns
Preliminary drying of raw materials not only reduces the duration of the process, but also affects the quality and yield of charcoal. It is recommended to apply preliminary drying, if the moisture content of raw material exceeds 30%.
Main advantages of the contact dryer:
- Increase kiln productivity
- Increase % charcoal yield
- Effective drying of "raw materials"
- Easy operation
- Low cost
From the table below, you can clearly see the difference in the cycle time at different humidity of the raw material for the production of charcoal.
|Relative humidity of wood, %||Cycle time, h.|
|< 20||> 12|
|< 40||> 16|
|< 55||> 24|
|< 70||> 36|

DESCRIPTION OF THE PRELIMINARY DRYING DEVICE
Excess heat generated as a result of carbonization of plant material enters the flue, using a high-temperature smoke exhauster (1). The hot gas is fed to the mixer (3), where its temperature is lowered to that required by mixing with cold air. The prepared heat transfer medium is then supplied through the distribution manifold (4) to the drying device (5), in this instance a kiln trolley.
