Iifom zezinto eziphambili ezenza i-biomass particle molding ziyi-particles of particle sizes, kunye neempawu zokuzalisa, iimpawu zokuhamba kunye neempawu zokunyanzeliswa kweengqungquthela ngexesha lokunyanzeliswa kwenkqubo yoxinzelelo kunempembelelo enkulu kwi-compression molding of biomass.

Ukubumba ukunyanzeliswa kwe-biomass pellet kwahlulwe ngokwezigaba ezibini.

Kwinqanaba lokuqala, kwinqanaba lokuqala loxinzelelo, uxinzelelo olusezantsi lutshintshelwa kwi-biomass ekrwada, ukuze i-original epakishwe ngokukhululekileyo isakhiwo solungiselelo lwezinto ekrwada iqala ukutshintsha, kwaye umlinganiselo wangaphakathi we-void we-biomass uyancipha.

Kwinqanaba lesibini, xa uxinzelelo lukhula ngokuthe ngcembe, i-roller yoxinzelelo yomatshini we-pellet ye-biomass iphula izinto eziluhlaza eziziinkozo ezinkulu phantsi kwesenzo soxinzelelo, ijika ibe ngamasuntswana acocekileyo, kunye ne-deformation okanye ukuhamba kweplastiki, amasuntswana aqala ukuzalisa. i-voids, kwaye amasuntswana ahlangene ngakumbi. I-mesh kunye nomnye xa idibene nomhlaba, kwaye inxalenye yoxinzelelo olushiyekileyo igcinwe ngaphakathi kweengqungquthela ezenziweyo, okwenza ukudibanisa phakathi kweengqungquthela zomelele.

I-finer i-raw materials eyenza iinqununu ezibunjiweyo, ukuphakama kweqondo lokuzalisa phakathi kweengqungquthela kunye noqhagamshelwano oluqinileyo; xa ubungakanani bamasuntswana amasuntswana buncinci ukuya kumlinganiselo othile (amakhulu ukuya kwimicrons ezininzi), amandla okudibanisa ngaphakathi kwamasuntswana amile kunye neprayimari kunye neyesibini nayo iya kutshintsha. Utshintsho lwenzeka, kwaye umtsalane wemolekyuli, umtsalane we-electrostatic, kunye nokunamathela kwesigaba solwelo (amandla e-capillary) phakathi kwamasuntswana aqala ukuphakama ukuba alawule.
Uphononongo lubonise ukuba ukunganyanzeki kunye ne-hygroscopicity yeengqungquthela ezibunjiweyo zihambelana ngokusondeleyo nobukhulu beengqungquthela. Iingqungquthela ezinobungakanani obuncinci bunobukhulu obuthile obukhulu, kwaye iinqununu ezibunjiweyo zilula ukufunxa umswakama kwaye ziphinde zifumane umswakama. Incinci, i-voids phakathi kweengqungquthela kulula ukuyizalisa, kwaye ukunyanzeliswa kuya kuba mkhulu, ukwenzela ukuba uxinzelelo lwangaphakathi olushiyekileyo ngaphakathi kweengqungquthela ezibunjiweyo lube luncinci, ngaloo ndlela lunciphisa i-hydrophilicity yeengqungquthela ezibunjiweyo kunye nokuphucula ukungaphumeleli kwamanzi.

Kuphononongo lwe-particle deformation kunye nefom yokubopha ngexesha lokunyanzeliswa kwezixhobo zezityalo, i-particle mechanical observation yenze ukubonwa kwe-microscope kunye ne-particle-dimensional-dimensional avareji yomlinganiselo we-avareji yomlinganiselo wamasuntswana ngaphakathi kwebhloko yokubumba, kwaye yaseka imodeli yokubopha i-particle microscopic. Kwisalathiso soxinzelelo oluphambili oluphambili, iinqununu zandisa kwiindawo ezijikelezayo, kwaye iinqununu zidibene ngendlela ye-meshing mutual; kwicala elihamba noxinzelelo oluphambili oluphezulu, iinqununu ziba zincinci kwaye zibe yi-flakes, kunye neengqungquthela zeengqungquthela zidibene ngendlela yokubambisana.

Ngokwale modeli yendibaniselwano, kunokucaciswa ukuba ukuthamba kwamasuntswana ezinto ezikrwada zebhayomass, kokukhona i-avareji ye-avareji ye-dimensional emibini iba nkulu, kwaye kulula ukuba i-biomass icinezelwe kwaye ibunjwe. Xa umxholo wamanzi kwizinto zezityalo ziphantsi kakhulu, iinqununu azikwazi ukwandiswa ngokupheleleyo, kwaye iinqununu ezijikelezayo azidibanisi ngokuqinileyo, ngoko azikwazi ukubunjwa; xa isiqulatho samanzi siphezulu kakhulu, nangona iinqununu zandiswe ngokupheleleyo kwicala le-perpendicular ukuya kuxinzelelo oluphambili oluphezulu, Iingqungquthela ziyakwazi ukuxutywa kunye, kodwa ekubeni amanzi amaninzi kwizinto eziluhlaza zikhutshwe kwaye zisasazwa phakathi kweengqimba zamaqhekeza, i-particle layers ayinakudityaniswa ngokusondeleyo, ngoko ayikwazi ukubunjwa.

Ngokwedatha yamava, injineli etyunjwe ngokukodwa yafikelela kwisigqibo sokuba kungcono ukulawula ubungakanani besuntswana lezinto ezikrwada ngaphakathi kwisinye kwisithathu sobubanzi bokufa, kwaye umxholo womgubo ocolekileyo awufanele ube phezulu kunoko. 5%.
