Torrefied Biomass Performs Better In The Pellet Mill

The process of torrefaction is still not that well known, however in the next few years torrefaction will be a common fuel process.

It can basically convert any form of biomass into a man made coal. The process of torrefaction involves heating wood or other biomass up to 300 degrees Celsius. In the torrefaction process due to the high temperature it is very important to remove all oxygen from the process. At these temperatures gasses are been released and the wood is very dry. Therefore if a spark caused ignition it could cause an explosion. Through heating the wood the unwanted aspects such as moisture and other volatiles are driven off. This makes a premium grade fuel. This fuel also repels water and does not produce any smoke during combustion. In terms of the pellet mill and hammer mill this material provides improved performance. It takes less energy to mill the material through the hammer mill, and it also takes less energy in the pellet mill to compress the material into pellets. Also, torrefied pellets contain twice the energy of a normal pellet and cost less to produce. Therefore it is clear that torrefied wood pellets will replace other wood pellets and biomass pellets. And as shown the gas generated in the torrefaction process can be used to run the process. Its the technology of the future.

You will also get a chance to view a series of videos on our UK made pellet presses and pellet plants. The mini pellet mill is for testing, the small pellet plants start from 250 kg/h for wood pellets and 400 kg/h for other lower density biomass. We design these plants to be highly automated to keep labour costs and other costs to a minimum.
