Panthawi ya granulation ya makina opangira chakudya, pali ma pellets a chakudya kapena ma pellets omwe ali ndi mitundu yosiyanasiyana, omwe amadziwika kuti "duwa lamaluwa".Izi zimachitika kawirikawiri popanga chakudya cham'madzi, chomwe chimawonetsedwa makamaka ngati mtundu wa tinthu tating'onoting'ono tomwe timatuluka kuchokera ku mphete kufa kukhala mdima kapena wopepuka kuposa tinthu tating'onoting'ono, kapena mtundu wamtundu wa tinthu tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono ting'ono ting'ono ting'ono ting'ono ting'ono ting'ono ting'ono ting'ono kukwera. gulu lonse la chakudya.
Zifukwa zazikulu za chochitikachi ndi izi:
a)Kapangidwe kazinthu zopangira chakudya ndizovuta kwambiri, zokhala ndi mitundu yambiri yazinthu zopangira, kusakanikirana kosagwirizana, komanso kusagwirizana kwa chinyezi chaufa musanayambe kukonza tinthu tating'onoting'ono ta chakudya.
b)Chinyezi chazinthu zopangira granulation sichikugwirizana.Popanga chakudya cham'madzi, nthawi zambiri pamafunika kuwonjezera madzi pang'ono kwa chosakanizira kuti athe kubwezera kutayika kwa madzi muzopangira pambuyo pophwanya ultrafine.Pambuyo kusakaniza, ndiye amatumizidwa kwa conditioner kuti kutentha.Opanga chakudya ena amagwiritsa ntchito njira yosavuta kwambiri popanga chakudya - ikani zinthu zomwe zimafunikira kuti muphatikizire mosakaniza ndikuwonjezera madzi okwanira, m'malo mongowonjezera mwatsatanetsatane komanso pang'onopang'ono malinga ndi zomwe akatswiri amafunikira.Chifukwa chake, zimawavuta kuwonetsetsa kugawa koyenera kwa zakudya zosakaniza potengera kusungunuka kwamadzi.Tikamagwiritsa ntchito zosakaniza izi zopangira chithandizo chamankhwala, tidzapeza kuti chifukwa cha mphamvu ya conditioner, chinyezi sichingathe kufalikira mofulumira mofanana.Chifukwa chake, kukhwima kwa zinthu zomwe zakonzedwa pansi pa nthunzi zimasiyana mosiyanasiyana, ndipo mawonekedwe amtundu pambuyo pa granulation samveka bwino.
c)Pali zinthu zobwezerezedwanso ndi granulation mobwerezabwereza mu bin granulation.Zinthu za granular pambuyo pa granulation zitha kusinthidwa kukhala zomalizidwa zitazizidwa ndikuwunika.Ufa wowoneka bwino kapena tinthu tating'onoting'ono nthawi zambiri umalowa munjira yopangira granulation, nthawi zambiri mu chosakanizira kapena kudikirira silo ya granulation.Chifukwa chakuti mtundu uwu wobwerera umasungidwa komanso kuphatikizidwa, ngati ukusakanikirana ndi zinthu zina zosagwirizana kapena zosakanizidwa ndi makina ang'onoang'ono a tinthu tating'onoting'ono.
d)Kusalala kwa khoma lamkati la kabowo ka mphete ndikosagwirizana.Chifukwa cha kusagwirizana kwapamtunda kwa dzenje la kufa, kukana ndi kukakamiza kwa extrusion komwe chinthucho chimakumana ndi extrusion ndizosiyana, zomwe zimapangitsa kuti mitundu isinthe.Komanso, ena mphete akamwalira ndi burrs pa yaing'ono dzenje makoma, amene akhoza zikande pamwamba pa particles pa extrusion, chifukwa mu mitundu yosiyanasiyana padziko kwa munthu particles.
Njira zowonjezera pazifukwa zinayi zopangira "zida zamaluwa" zomwe zatchulidwa pamwambapa ndizomveka bwino, makamaka kuyang'anira kusakanikirana kosakanikirana kwa chigawo chilichonse mu ndondomeko ndi kusakaniza kufanana kwa madzi owonjezera;Kupititsa patsogolo ntchito yozimitsa ndi kutentha kungachepetse kusintha kwamtundu;Sinthani makina obwerera.Kwa mafomu omwe amakonda kupanga "maluwa", yesetsani kusadulira mwachindunji makina obwerera.Makina obwerera ayenera kusakanizidwa ndi zopangira ndikuphwanyidwanso;Gwiritsani ntchito mphete zapamwamba kwambiri kuti muchepetse kusalala kwa mabowo, ndipo ngati kuli kofunikira, perani mabowo a mphete musanagwiritse ntchito.
Ndikofunikira kuti mukonze chowongolera chamitundu iwiri chamitundu iwiri komanso chowongolera jekete chokhala ndi magawo awiri, chokhala ndi nthawi yozimitsa mpaka masekondi 60-120 ndi kutentha kozimitsa kupitilira 100 ℃.Kuzimitsa ndi yunifolomu ndipo ntchito ndi yabwino kwambiri.Kugwiritsiridwa ntchito kwa mpweya wambiri kumawonjezera kwambiri gawo lazakudya ndi nthunzi, potero kumapangitsa kukhwima kwa zinthu ndikuwongolera kuzimitsa ndi kutentha;Chida cha digito ndi sensa ya kutentha imatha kuwonetsa kutentha kwa chikhalidwecho, ndikupangitsa kuti ogwiritsa ntchito aziwongolera nthawi iliyonse.
