Mitundu yayikulu yomwe imapanga biomass particle ndi tinthu tating'ono ting'onoting'ono tosiyanasiyana, ndipo mawonekedwe odzaza, mawonekedwe otaya ndi mawonekedwe a minyewa ya tinthu tating'onoting'ono panthawi ya psinjika amakhala ndi chikoka chachikulu pakuwumbidwa kwa biomass.

Kuumba kwa biomass pellet compression kumagawidwa m'magawo awiri.

Mu gawo loyamba, mu gawo loyambirira la psinjika, kuthamanga kwapansi kumasamutsidwa ku zotsalira zotsalira zotsalira, kotero kuti zoyambira zodzaza zopangira zoyambira zimayamba kusintha, ndipo chiŵerengero chapakati chopanda kanthu cha biomass chimachepa.

Mu gawo lachiwiri, pamene kupanikizika kumawonjezeka pang'onopang'ono, makina osindikizira a biomass pellet amathyola zipangizo zazikuluzikulu pansi pa kukakamizidwa, kusandulika kukhala tinthu tating'onoting'ono, ndipo kusinthika kapena kutuluka kwa pulasitiki kumachitika, tinthu tating'onoting'ono timayamba kudzaza. voids, ndipo tinthu tating'onoting'ono timakhala tambirimbiri. Amalumikizana wina ndi mnzake akakumana ndi nthaka, ndipo gawo lina la kupsinjika kotsalira limasungidwa mkati mwa tinthu tating'onoting'ono tomwe timapanga tinthu tating'onoting'ono tomwe timapanga tinthu tating'onoting'ono.

Zomwe zimapangidwa bwino zomwe zimapanga tinthu tating'onoting'ono tomwe timapanga tinthu tating'onoting'ono, timakulitsa digirii yodzaza pakati pa tinthu tating'onoting'ono ndikulumikizana kolimba; pamene tinthu kukula kwa particles ndi yaing'ono kumlingo winawake (mazana angapo microns), ndi kugwirizana mphamvu mkati zooneka particles ndi pulayimale ndi sekondale ngakhale adzasinthanso. Zosintha zimachitika, ndipo kukopa kwa mamolekyulu, kukopa kwa electrostatic, ndi kumamatira kwamadzimadzi (capillary force) pakati pa tinthu tating'onoting'ono timayamba kukwera.
Kafukufuku wasonyeza kuti kusatheka ndi hygroscopicity wa particles kuumbidwa zimagwirizana kwambiri ndi tinthu kukula kwa tinthu. Tinthu tating'onoting'ono tokhala ndi tinthu tating'onoting'ono timakhala ndi malo akuluakulu enieni, ndipo tinthu tomwe timapanga timasavuta kuyamwa chinyezi ndikubwezeretsanso chinyezi. Small, ndi voids pakati particles n'zosavuta kudzaza, ndi compressibility amakhala wamkulu, kotero kuti otsala mkati nkhawa mkati zooneka particles amakhala ang'onoang'ono, potero kufooketsa hydrophilicity wa zooneka particles ndi kuwongolera impermeability madzi.

Pophunzira za tinthu mapindikidwe ndi kumanga mawonekedwe pa psinjika akamaumba zipangizo zomera, ndi tinthu makina injiniya anachita kuonerera maikulosikopu ndi tinthu awiri azithunzithunzi pafupifupi awiri muyeso wa particles mkati akamaumba chipika, ndipo anakhazikitsa tinthu ting'onoting'ono kumanga chitsanzo. Kumbali ya kupsinjika kwakukulu kwakukulu, tinthu tating'onoting'ono timafikira kumadera ozungulira, ndipo tinthu tating'onoting'ono timaphatikizidwa mu mawonekedwe a mutual meshing; m'njira pamodzi pazipita chachikulu nkhawa, ndi particles kukhala woonda ndi kukhala flakes, ndi zigawo tinthu timaphatikizana mu mawonekedwe a mgwirizano kugwirizana.

Malinga ndi chitsanzo ichi osakaniza, tingathe kufotokozedwa kuti softer ndi particles wa zotsalira zazomera yaiwisi, m'pamenenso awiri-dimensional pafupifupi awiri awiri a tinthu tating'onoting'ono amakhala lalikulu, ndipo mosavuta zotsalira zazomera ndi wothinikizidwa ndi kuumbidwa. Madzi omwe ali muzomera zinthuzo ndi otsika kwambiri, tinthu timeneti tingathe kuwonjezera, ndipo tinthu tating'onoting'ono osaphatikizika, chifukwa sangapangidwe; pamene madzi okhutira ndi ochuluka kwambiri, ngakhale particles mokwanira anawonjezera mu malangizo perpendicular kwa pazipita waukulu nkhawa, The particles akhoza meshed pamodzi, koma popeza madzi ambiri mu zopangira ndi extruded ndi kugawira pakati pa tinthu zigawo, zigawo za tinthu sizingagwirizane kwambiri, kotero sizingapangidwe.

Malinga ndi zomwe zidachitika, injiniya wosankhidwa mwapadera adazindikira kuti ndi bwino kuwongolera kukula kwa tinthu tating'onoting'ono mkati mwa gawo limodzi mwa magawo atatu a m'mimba mwake mwa ufa, ndipo zomwe zili mu ufa wabwino siziyenera kukhala zapamwamba kuposa. 5%.
