The invention relates to a
biomass fuel particle and a
processing device and method thereof. The
biomass fuel particle is prepared from the components: 15 parts of rice husks, 25 parts of
straw, 10 parts of wood scraps, 3 parts of corn cobs, 35 parts of rice and wheatgrass, 5 parts of tree roots, 35 parts of wood chips, 10 parts of
bagasse, 5 parts of
cottonseed shells, 3 parts of a dehydrator, 1part of pecan shells and 1 part of bamboo chips. The
processing method includes the following steps that step 1,
biomass fuel is put into a fuel
processing cylinder; step 2, a reciprocating drive
assembly starts to drive a stirring plate and a spiral stirring blade move up and down in a reciprocating mode, and the biomass fuel is rotated and stirred up and down in a reciprocating mode; step 3, a
particle processing driving part starts to drive two pressing rollers to rotate, and the two pressing rollers extrude the biomass fuel from a circular through hole by the cooperation with a round holeseat plate; step 4, the
particle processing driving part drives a
cutting knife mechanism to rotate, and the rotary
cutting knife mechanism cuts the extruded column-shaped biomass fuel into
grain shape; and step 5, biomass fuel particles fall into a material receiving box to be collected.
