Cov khoom siv raw uas xav tau rau pelletizing nyob rau hauv feed pellet tshuab muaj xws li ntau yam nplej, soybean pluas noj, ntses noj, thiab lwm yam. Cov khoom siv raw yuav tsum tau soj ntsuam nruj me ntsis thiab ntxuav kom lawv zoo thiab purity. Nyob rau tib lub sijhawm, raws li kev xav tau ntawm cov mis sib txawv, kuj yuav tsum tau ntxiv cov tshuaj ntxiv thiab cov vitamins.
Tom ntej no yog lub pretreatment ua ntej granulation. Cov kauj ruam no suav nrog kev ua haujlwm xws li crushing, sib tov thiab tempering ntawm raw cov ntaub ntawv. Crushing yog rhuav tshem cov ntaub ntawv raw rau hauv cov khoom me me kom yooj yim rau cov txheej txheem granulation tom ntej. Kev sib xyaw yog kom sib npaug ntawm cov khoom xyaw kom ntseeg tau qhov zoo thiab ruaj khov ntawm cov khoom noj. Tempering yog los kho cov av thiab qhov kub thiab txias ntawm cov ntaub ntawv raw kom lawv haum rau pelletizing. Tom qab ntawd los ntawm txheej txheem pelleting. Pelleting yog txheej txheem ntawm nias cov khoom ua ntej kho rau hauv granules los ntawm lub tshuab pelletizing. Hauv cov txheej txheem no, cov khoom siv raw yog pub rau hauv granulator, thiab tom qab compression thiab kev sib txhuam, lawv maj mam tsim granules. Nyob rau tib lub sijhawm, lub granulator tseem tswj qhov loj, zoo li qub thiab hardness ntawm granules los ntawm kev kho cov tsis xws li siab, kub thiab noo noo.
