1. Cov khoom siv nthuav dav: Cov khoom siv nthuav dav yog hais txog kev nthuav dav ntawm cov khoom noj khoom haus ceev ceev nyob rau hauv qhov kub thiab txias, kev kub siab, thiab cov cua kub cua sov, tsim cov khoom ntxeem tau. Cov txiaj ntsig zoo ntawm cov khoom siv puffing muaj xws li:
- Txhim kho kev siv cov khoom noj: Cov txheej txheem puffing tuaj yeem txhim kho kev siv khoom noj. Kev nthuav dav tuaj yeem hloov pauv lub cev ntawm cov khoom noj khoom haus, ua kom cov protein ntau zom zom thiab nqus tau, thiab nce Mashing tus nqi, uas yuav pab tau los txhim kho kev noj zaub mov kom zoo thiab kev loj hlob ceev ntawm cov tsiaj.
-Sterilization thiab tshuaj tua kab: Qhov cuam tshuam ntawm qhov kub thiab txias thaum lub sij hawm puffing txheej txheem tuaj yeem tua cov kab mob thiab cov kab mob hauv cov khoom noj, txo cov kev pheej hmoo ntawm cov tsiaj txhu, thiab txhim kho kev noj qab haus huv ntawm cov tsiaj.
- Txhim kho qhov saj ntawm cov khoom noj: Kev nthuav dav tuaj yeem txhim kho saj ntawm cov khoom noj, ua kom qab los noj mov, txhawb cov tsiaj noj ib txwm, thiab txo cov khoom noj.
2. Pub pellet: Pub pellet yog cov khoom siv granular ua los ntawm pub rau ib qho loj thiab cov duab. Cov txiaj ntsig zoo ntawm kev pub pellets muaj xws li:
- Txhim kho qhov ruaj khov ntawm cov khoom noj: Granular pub pab sib tov sib xyaw thiab ruaj khov cov khoom xyaw, txo cov txheej txheem thiab tso tawm ntawm ntau yam khoom noj, txhim kho kev noj zaub mov zoo, thiab ua kom cov tsiaj tau txais kev noj zaub mov zoo.

Cov duab tsis tu ncua thiab cov khoom siv ntawm cov khoom siv granular ua rau qhov chaw khaws cia ntau dua, ua kom yooj yim khaws cia thiab kev thauj mus los, thiab txo cov khoom noj thiab pov tseg.
-Txhim kho rau cov tsiaj sib txawv: cov khoom siv granular tuaj yeem npaj rau hauv qhov sib txawv ntawm qhov sib txawv thiab cov duab, uas tuaj yeem hloov kho raws li tus qauv ntawm lub qhov ncauj thiab kev zom zaub mov ntawm cov tsiaj sib txawv, muab pub rau zom thiab zom cov tsiaj sib txawv.
Hauv cov ntsiab lus, cov txheej txheem ntawm kev xaiv ntawm extruded pub lossis pellet pub nyob ntawm qhov xwm txheej tshwj xeeb. Yog tias koj nrhiav qhov zoo hauv kev txhim kho kev siv cov khoom noj, kev ua kom tsis muaj menyuam thiab kev tswj xyuas kab tsuag, thiab kev txhim kho saj, koj tuaj yeem xaiv cov khoom noj khoom haus puffing; Yog tias koj ua raws li qhov zoo ntawm kev noj zaub mov ruaj khov, kev cia yooj yim thiab kev thauj mus los, thiab kev yoog raws cov tsiaj xav tau sib txawv, koj tuaj yeem xaiv cov khoom noj pellets. Nyob rau tib lub sijhawm, kev ua zaub mov sib txawv kuj tseem tuaj yeem txiav txim siab raws li yam xws li hom tsiaj, theem kev loj hlob, thiab kev pub mis.
Xyoo 2020, kev tsim cov khoom noj hauv dej hauv Suav teb tau txog 21.236 lab tons. Txij xyoo 1995 txog 2020, cov khoom noj hauv dej tau tswj hwm kev loj hlob sai hauv kev lag luam pub khoom noj thiab cia siab tias yuav muaj qhov chaw ruaj khov thiab loj loj nyob rau yav tom ntej.
Expanded pub, tseem hu ua clinker, yog ua tiav los ntawm cov txheej txheem puffing. Kev nthuav dav ntawm cov khoom noj khoom haus hloov pauv lawv cov tsos, qauv, thiab txawm tias cov organic teeb meem, ua rau lawv zoo dua rau kev zom thiab nqus los ntawm cov tsiaj.
Cov txheej txheem ntau lawm ntawm puffed pub thiab pellet pub feem ntau txawv nyob rau hauv ntau theem xws li txias, puffing, thiab kua txau:
1. Tempering: Tom qab tempering, cov dej noo ntawm cov khoom puffed yog li 25%, thaum cov khoom granular yog li ntawm 17%. Thiab thaum kho qhov zoo ntawm cov ntaub ntawv puffed, dej thiab chav ntxiv ua ke, thaum rau cov ntaub ntawv granular, tsuas yog chav ntxiv.
2. Kev nthuav dav thiab txau: Cov khoom siv nthuav dav yog tsim los ntawm kev nthuav dav thiab txau, siv cov tshuab tshwj xeeb nthuav dav thiab cov khoom siv roj txau. Tom qab txau, cov khoom noj muaj cov tsos zoo, muaj zog palatability, thiab muaj zog noj zaub mov muaj nqis.
