The torrefaction is a heat treatment which aims to modify the properties of various wood varieties. Unlike a conventional drying, torrefaction is done at high temperature, in the range of 160°C to 250°C [320°F to 490°F]. The torrefied wood develops increased resistance to deterioration, fungal attack as well as insects. In addition, the wood becomes hydrophobic, ie water will pearl on is surface and does not penetrate the fiber. It is not necessary to chemically treat the torrefied wood for use in external applications. Finally, the torrefaction can change the shade of the wood. Thus, woods varieties with paler shades can be torrefied from golden honey to very dark colors. Airex Industries has developed a high end technology biomass torrefaction oven for performing treatment on wood. It was designed and created to meet the needs of this particular application. The biomass torrefaction oven is intended to be fully autonomous, requiring a minimum of human intervention. Simply insert the wood into the oven, entering the starting data in the computer and the oven will do the rest! First, the load of wood has to be stacked on the cart specially designed for this application. The cart is introduced in the biomass torrefaction oven with the help of the rail system that allows the insertion and extraction of the wood, effortlessly and securely. Once done, simply lock the door properly. It remains only to enter the technical data relating to the variety wood to be torrefied in the computer and the process begins. All stages are fully managed by the biomass torrefaction oven computer.
