The biomass pellet machine uses agricultural and forestry processing waste such as wood chips, straw, rice husks, bark and other biomass as raw materials.
What are the characteristics of the four major components of biomass materials?
Lignin, lignin has a larger specific gravity and is sticky. However, the release of this viscosity requires some conditions. That is the reason why the pellet machine can combine biomass materials into pellets, because lignin releases viscosity. When the viscosity of lignin reaches the certain conditions, lignin will be released.
Cellulose, cellulose has a small specific gravity, which means it is relatively light and fibrous. It is also one of the essential components why our biomass materials can be extruded into pellets.
Sugar and oil, sugar and oil are both non-flammable organic matter. Sometimes biomass fuel pellets will coke and slag inside, and some materials are difficult to be pressed. This is related to the two components of sugar and oil. Sugar is a non-flammable organic substance and is relatively sticky, which will cause the material to coke. For example, straw materials, especially corn stalks, contain a lot of sugar. When the fuel pellets are burned, they will form some sticky objects, because sugar is a non-flammable organic matter, which is the core of the pellets coking.
Oil content: Pinus tabulaeformis and palm shell have relatively high oil content. In this case, pressing the pellets will cause the material to swell during the process of forming the pellets, making our pressing process more difficult.
