PELLET EXTRUSION DEVICE

摘要

A reliable, energy-efficient pellet extrusion system [100] is described which creates pellets [170] from a biomass material [16]. It employs equipment which pre-processes the biomass material [16]. Biomass material [16] is then provided to a pellet mill [1000]. The biomass [16] material is provided into a drum [1300] of a pellet mill [1000]. The pellet mill [1000] has a plurality of extrusion holes [1200] and at least one roller [1400]. The rollers [1400] have protrusions [1420] sized and shaped to match up with the holes [1200] of the drum [1300]. As the drum [1300] and rollers [1400] turn, protrusions [1420] of roller [1400] meet with holes [1200] of drum [1300] pressing the biomass [16] out of extrusion holes [1200] as pellets [170]. Since the protrusions [1420] only align with holes [1200], the biomass [16] is extruded through the plurality of extrusion holes [1200] without a significant increase in pressure. This design results in less energy expended and lost thereby creating less wear and failure, resulting in a more efficient, more reliable pellet extrusion device.
