Ua ntej tshaj plaws, cov khoom siv raw uas xav tau rau lub tshuab pub pellet rau pellet muaj xws li ntau yam nplej, taum noj, ntses noj, thiab lwm yam. Cov khoom siv raw yuav tsum tau soj ntsuam nruj me ntsis thiab ntxuav kom zoo thiab purity. Nyob rau tib lub sijhawm, raws li qhov xav tau ntawm cov qauv sib txawv, qhov tsim nyog ntawm cov tshuaj ntxiv thiab cov vitamins yuav tsum tau ntxiv. 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 khoom. Tom qab ntawd los ntawm cov txheej txheem granulation. Granulation yog txheej txheem uas cov khoom siv raw khoom tau raug nias rau hauv daim ntawv granular los ntawm granulator.
Cov kauj ruam kawg yog ua kom txias thiab ntim khoom. Cov granulated particles yuav tsum tau txias kom txo lawv qhov kub thiab ua kom lawv ruaj khov. Cov pellets ces muab tso rau hauv lub tshuab ntim khoom ntim rau kev thauj mus los yooj yim thiab siv tau. Thoob plaws hauv tag nrho cov txheej txheem granulation, qhov zoo thiab kev nyab xeeb yuav tsum tau tswj nruj me ntsis ntawm txhua qhov txuas. Nyob rau tib lub sijhawm, txhawm rau txhawm rau txhim kho kev tsim khoom thiab txo cov nqi, nws yog ib qho tsim nyog yuav tsum ua kom zoo dua cov txheej txheem ntws thiab cov txheej txheem tsis tu ncua. Tsuas yog nyob rau hauv txoj kev no peb tuaj yeem tsim cov khoom lag luam zoo, ua haujlwm siab noj pellet kom tau raws li kev xav tau ntawm kev lag luam.
