Kab rov tav tawg traverses tag nrho cov ntoo pellet, uas yog me ntsis zoo ib yam li qhov tshwm sim nyob rau hauv Case 1. Qhov tawg tshwm sim nyob rau hauv lub cross-section ntawm ntoo pellet, tab sis lub pellet tsis khoov. Qhov no tuaj yeem tshwm sim thaum prilling fluffy ntoo chips uas muaj fiber ntau. Hom ntoo pellets no feem ntau yog thaum cov ntoo pellets raug nyem rau hauv lub pelletizing qhov ntawm lub nplhaib tuag. Vim tias lawv muaj cov fibers ntev dua li qhov aperture, thaum cov pellets raug extruded, cov pellets yuav muaj cov kab nrib pleb ntawm qhov hla ntu vim qhov nthuav dav ntawm cov fibers. , Ua rau cov tsos ntawm fir-bark zoo li sawdust hais. Sawdust hais ua cov kab nrib pleb. Thaum lub sij hawm tsim khoom, qee cov neeg siv khoom tsis tuaj yeem sib npaug ntawm cov sawdust vim yog xaiv hom tshuab ziab khaub ncaws, ua rau cov dej tsis sib xws hauv cov ntoo nyoos. Cov nyhuv ntawm qhov hnyav thiab elasticity ntawm raw khoom nws tus kheej bounced tam sim ntawd, ua rau cov kab nrib pleb.

Cov sawdust hais tsim hluav taws xob tawg los ntawm qhov chaw taw tes. Lub ntsiab yog vim li cas rau qhov teeb meem no yog hais tias sawdust muaj kuj loj sawdust. Cov ntaub ntawv raw nrog tib qib ntawm fiber ntau yuav nyem thiab fuse ib leeg thaum lawv pelletized. Yog tias muaj fiber ntau loj, kev sib cuam tshuam ntawm cov fibers yuav cuam tshuam. Nws tsis yooj yim rau soften li lwm cov ntaub ntawv zoo, thiab thaum nws txias, vim qhov sib txawv softening degrees, qhov sib txawv ntawm shrinkage ua rau tawg tawg.
