JNSHARE biomass pellet machine is based on the fact that wood chips, straw and other materials contain a certain amount of cellulose and lignin, among which lignin is a structural monomer in the material and a phenylpropane-type high molecular compound. It has the function of strengthening cell walls and bonding cellulose. Lignin is a non-crystalline material, and the main part is insoluble in any solvent at room temperature. It has no melting point but a softening point. When the temperature reaches a certain value, the lignin softens and the bonding force increases, and under a certain effect, the cellulose molecular groups are dislocated, deformed, and extended, and the adjacent biomass pelletinside are meshed with each other, recombined, and pressed to form biomass pellet fuel.
