Hauv kev ua cov khoom noj, kev siv cov txheej txheem pub mis thiab cov txheej txheem pub pellet yuav txiav txim siab lawv cov txiaj ntsig.

1. Cov khoom siv nthuav dav pub: Cov khoom siv nthuav dav pub yog hais txog kev nthuav dav sai ntawm cov khoom siv pub hauv qab qhov kub siab, siab siab, thiab cua sov noo, tsim cov khoom me me nthuav dav. Cov txiaj ntsig ntawm cov khoom siv pub suav nrog:

-Txhim kho kev siv cov khoom noj pub: Cov txheej txheem ua kom cov khoom noj tuaj yeem txhim kho kev siv cov khoom noj. Kev nthuav dav tuaj yeem hloov pauv cov khoom siv ntawm cov khoom noj, ua rau cov protein zom tau thiab nqus tau zoo dua, thiab ua rau Mashing nrawm dua, uas yog qhov pab tau los txhim kho kev hloov pauv ntawm cov khoom noj thiab kev loj hlob sai ntawm cov tsiaj.

-Kev ua kom tsis muaj kab thiab tswj kab tsuag: Cov teebmeem ntawm qhov kub thiab txias siab thaum lub sijhawm ua kom cov kab mob tuaj yeem tua cov kab mob thiab cov kab mob hauv cov khoom noj, txo qhov kev pheej hmoo ntawm kev kis tus kab mob ntawm tsiaj, thiab txhim kho qib kev noj qab haus huv ntawm cov tsiaj.

-Txhim kho qhov saj ntawm cov khoom noj: Kev nthuav dav tuaj yeem txhim kho qhov saj ntawm cov khoom noj, ua rau kom muaj kev tshaib plab, txhawb kev noj tsiaj ib txwm muaj, thiab txo cov khib nyiab pub.

2. Cov khoom noj pellet: Cov khoom noj pellet yog cov khoom siv granular ua los ntawm cov khoom noj kom muaj qee qhov loj me thiab cov duab. Cov txiaj ntsig ntawm cov khoom noj pellet suav nrog:

-Txhim kho qhov ruaj khov ntawm cov khoom noj: Cov khoom noj granular pab kom sib tov thiab ruaj khov cov khoom xyaw pub, txo cov txheej thiab kev tso cov khoom sib txawv hauv cov khoom noj, txhim kho kev ruaj khov ntawm cov khoom noj, thiab xyuas kom meej tias cov tsiaj tau txais kev noj haus zoo.

-Kev khaws cia thiab kev thauj mus los yooj yim: Cov khoom siv granule yooj yim khaws cia thiab thauj mus los, thiab tsis yooj yim rau cov dej noo, pwm, thiab oxidation. Cov duab zoo li qub thiab cov khoom khov kho ntawm cov khoom siv granule ua rau qhov chaw khaws khoom zoo dua, yooj yim khaws cia thiab thauj mus los, thiab txo cov khoom noj poob thiab pov tseg.

-Hloov kho rau cov tsiaj xav tau sib txawv: Cov khoom siv granular tuaj yeem npaj ua cov khoom me me ntawm ntau qhov ntau thiab tsawg thiab cov duab, uas tuaj yeem hloov kho raws li cov qauv qhov ncauj thiab cov yam ntxwv ntawm kev zom zaub mov ntawm cov tsiaj sib txawv, muab cov khoom noj uas tsim nyog rau kev zom thiab zom zaub mov ntawm cov tsiaj sib txawv.

Hauv kev xaus lus, cov txheej txheem ntawm kev xaiv ntawm cov khoom noj uas raug rho tawm lossis cov khoom noj pellet nyob ntawm qhov xwm txheej tshwj xeeb. Yog tias koj nrhiav qhov zoo hauv kev txhim kho kev siv cov khoom noj, kev tua kab mob thiab kev tswj kab tsuag, thiab kev txhim kho saj, koj tuaj yeem xaiv cov khoom siv pub mis; Yog tias koj nrhiav qhov zoo ntawm kev ruaj khov ntawm cov khoom noj, kev khaws cia thiab kev thauj mus los yooj yim, thiab kev hloov pauv rau cov kev xav tau ntawm cov tsiaj sib txawv, koj tuaj yeem xaiv cov khoom noj pellets. Tib lub sijhawm, cov txheej txheem ua cov khoom noj sib txawv kuj tuaj yeem txiav txim siab raws li cov yam ntxwv xws li hom tsiaj, theem kev loj hlob, thiab cov txheej txheem 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 tsiaj thiab xav tias yuav muaj qhov chaw lag luam ruaj khov thiab loj heev yav tom ntej.

Cov khoom noj uas nthuav dav, tseem hu ua clinker, yog ua tiav los ntawm cov txheej txheem puffing. Kev nthuav dav ntawm cov khoom siv pub mis hloov pauv lawv cov tsos, cov qauv, thiab txawm tias cov organic teeb meem, ua rau lawv yooj yim dua rau kev zom thiab nqus los ntawm cov tsiaj.

Cov txheej txheem tsim khoom ntawm cov khoom noj uas muaj ...

1. Tempering: Tom qab tempering, cov dej noo ntawm cov khoom puffed yog li 25%, thaum cov khoom granular yog li 17%. Thiab thaum kho qhov zoo ntawm cov khoom puffed, dej thiab pa dej ntxiv ua ke, thaum rau cov khoom granular, tsuas yog pa dej ntxiv.

2. Kev nthuav dav thiab txau: Cov khoom siv nthuav dav feem ntau yog tsim tawm hauv qhov chaw nthuav dav thiab txau, siv cov tshuab nthuav dav tshwj xeeb thiab cov khoom siv txau roj. Tom qab txau, cov khoom noj muaj qhov zoo nkauj, saj zoo, thiab muaj txiaj ntsig zoo rau kev noj qab haus huv. Cov khoom siv granular tsis muaj ob txoj hauv kev no, tab sis muaj cov txheej txheem granulation ntxiv.

Cov khoom noj uas nthuav dav siv cov khoom zom zoo heev, uas muaj cov khoom me me dua piv rau cov khoom siv granular thiab yooj yim dua rau kev nqus. Txawm li cas los xij, vim muaj qhov kub thiab txias siab, kev puas tsuaj ntawm cov protein tuaj yeem tshwm sim. Qhov kub ua tiav ntawm cov khoom siv granular yog li 80 degrees Celsius, thiab yeej tsis muaj kev poob ntawm cov khoom noj khoom haus, tab sis cov kab mob, cov pwm, thiab lwm yam hauv nws tsis tuaj yeem tua tag nrho. Yog li ntawd, piv rau cov khoom siv granular ib txwm muaj, cov khoom siv puffed muaj kev nyab xeeb dua thiab txo qhov kev pheej hmoo ntawm kab mob tsiaj.
