What Is The Specific Process Of The Straw Pellet Machine During Operation?

The straw pellet machine uses the principle of interaction between the extrusion force and friction between the pressing wheel and the mold to shape the material. No additives or binders are needed during the processing of the material. Straw and other materials contain a certain amount of cellulose and lignin. Lignin is a structural monomer in the material and a phenylpropane-type polymer compound. It has the function of strengthening the cell wall and bonding cellulose. Lignin is a non-crystalline material. The main part of it 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 softening and bonding force of lignin increases, and under a certain pressure, the cellulose molecular groups are dislocated, deformed, and extended, and the adjacent biomass particles inside are meshed with each other, recombined, and pressed into shape.

So what is the specific process of the straw pellet machine in operation?

The process flow of the straw pellet machine includes: first crushing straw, then microbial treatment (if not micro-treated, it can also be processed directly, but the protein content cannot be increased. The protein content of micro-treated straw will generally increase by more than 3 times.

Because the straw pellet machine is not easy to form, the pellet machine of the traditional process will have problems such as mold, easy damage of bearing, difficult material forming, and serious blockage of mold. On the one hand, many manufacturers do not have their technology but just imitate blindly, and on the other hand, they are reluctant to invest, the equipment technology is outdated, and the equipment parts are unqualified. Using a straw pellet machine can ensure the effective utilization of straws and carry out simple storage.
