Mitundu yayikulu yomwe imapanga biomass particle ndi tinthu tating'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, koyambirira kwa psinjika, kupanikizika kwapansi kumasamutsidwa ku zotsalira zotsalira zotsalira, kotero kuti zoyambira zodzaza zopangira zoyambira zimayamba kusintha, ndipo chiŵerengero chopanda kanthu chamkati cha biomass chimachepa.

Mu gawo lachiwiri, 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, zomwe zimapangitsa mgwirizano pakati pa tinthu tating'onoting'ono tolimba.

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 timapangidwa timasavuta kuyamwa chinyezi ndikubwezeretsanso chinyezi.Small, ndi voids pakati particles n'zosavuta kudzaza, ndi compressibility amakhala wamkulu, kotero kuti yotsalira mkati nkhawa mkati zooneka particles amakhala ang'onoang'ono, potero kufooketsa hydrophilicity zooneka particles ndi kuwongolera impermeability madzi.

Mu phunziro la tinthu mapindikidwe ndi kumanga mawonekedwe pa psinjika akamaumba zipangizo zomera, ndi tinthu makina injiniya anachita kuonerera maikulosikopu ndi tinthu awiri azithunzithunzi pafupifupi m'mimba mwake 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 waukulu nkhawa, ndi particles kukhala woonda ndi kukhala flakes, ndi zigawo tinthu pamodzi mu mawonekedwe a kugwirizana kugwirizana.

Malinga ndi chitsanzo ichi osakaniza, tingathe kufotokozedwa kuti softer particles wa zotsalira zazomera zopangira zopangira, mosavuta awiri azithunzithunzi pafupifupi awiri a tinthu tating'onoting'ono awiri a particles amakhala lalikulu, ndi zosavuta 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 zigawo tinthu, 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, ndipo zomwe zili mu ufa wabwino siziyenera kukhala zapamwamba kuposa 5%.
