DESIGN OF BIDIRECTIONAL SCREW EXTRUSION BIOMASS HONEYCOMB BRIQUETTE MACHINE.

Biomass densification machines can compress crushed crop straw and other agricultural residues into biomass densified fuels with a specific shape and density under certain external force, temperature, and humidity conditions. Existing biomass densification machines primarily produce solid biomass fuels in the form of rods, blocks, and pellets. In order to improve the moulding efficiency of biomass briquette machines and increase the effective contact area between biomass fuel and oxygen during combustion, a bidirectional screw extrusion biomass honeycomb briquette machine is designed. The briquette machine consists of two main components, the screw extrusion device and the moulding device. The screw extrusion device facilitates continuous material transport via a screw, while the moulding device compresses the crushed biomass material into a honeycomb shape within the moulding sleeve through a crank-slider mechanism. Additionally, since the densification machine compresses the biomass material from two directions, it enhances the production efficiency of biomass densified fuels. The design of this briquette machine is of significance for promoting the widespread use of biomass densified fuels. [ABSTRACT FROM AUTHOR]
