1. Nrog rau lub sijhawm tsis muaj tshuaj tua kab mob, cov tshuaj uas rhiab heev rau cua sov xws li probiotics maj mam ntxiv rau hauv cov pub pellet. Yog li ntawd, thaum lub sijhawm tsim khoom noj, qhov kub kuj tseem yuav muaj qhov cuam tshuam tseem ceeb rau qhov zoo ntawm cov pub pellet. Yog tias qhov kub siab dhau thaum lub sijhawm tsim khoom noj pellet, nws yuav tua cov tshuaj uas rhiab heev rau cua sov xws li probiotics. Yog tias qhov kub qis dhau, cov kab mob hauv cov pub pellet yuav tsis raug tua kom huv si, ua rau cov khoom noj pellet tsim tau. Qhov zoo tsis zoo. Yog li ntawd, txhawm rau kom tsis txhob muaj kev cuam tshuam ntawm qhov kub rau qhov kev xeem, qhov kev xeem no yog los kawm txog kev cuam tshuam ntawm qhov kub thiab txias thiab qhov sib piv ntawm qhov tuag rau qhov zoo ntawm cov khoom noj pellet hauv qab qhov kub qis, yog li kawm txog kev tsim cov pellets ntawm cov khoom noj pellet hauv qab cov xwm txheej sib xws tom qab cov khoom siv raw tau loj hlob. Seb nws puas puv thiab seb nws puas ua tau raws li cov qauv rau kev sim zoo ntawm cov khoom me me. Lub hom phiaj tseem ceeb ntawm qhov kev sim no yog los muab qee qhov kev taw qhia theoretical rau kev tsim cov tsiaj txhu pellet pub.
2.1 Cov khoom xyaw tseem ceeb ntawm cov khoom noj sim thiab cov khoom siv raw pellet suav nrog: pob kws, ntses hmoov, ntsev, methionine, threonine, thiab lwm yam. Cov pob kws yuav tsum tau muab tsoo ua cov khoom me me 11.0 hli, thiab tom qab ntawd cov khoom siv raw raug faib ua feem raws li qhov xav tau ntawm cov khoom noj khoom haus, thiab tom qab ntawd laus. Tom qab txias, cov tshuaj uas rhiab heev rau cua sov xws li probiotics raug ntxiv, thiab thaum kawg tempered rau hauv cov khoom me me. Qhov kub ntawm cov khoom noj pellets txias feem ntau yog 60, 50, 40, thiab 30 ° C, thiab qhov ntev thiab txoj kab uas hla ntawm cov qhov tuag feem ntau yog 7: 1, 6: 2, thiab 10: 1, thiab 300 mg / kg ntawm cov tshuaj probiotic raug ntxiv raws li cov ntaub ntawv sim. , thiab qhov kub ntawm cov khoom noj pellet kuj yuav tsum tau tempered los tiv thaiv cov haujlwm ntawm probiotics. Tsis tas li ntawd, qee cov vitamins yuav tsum tau ntxiv rau txhua kilogram ntawm cov khoom noj pellet kom ntseeg tau tias cov khoom noj khoom haus ntawm cov khoom noj pellet tuaj yeem ua tau raws li cov kev xav tau ntawm lub tebchaws.
2.2 Kev kuaj thiab sau cov qauv
Yuav kom ntseeg tau tias cov khoom noj pellet tsim tau zoo, tom qab cov khoom noj pellet tsim tawm, nws yog ib qho tsim nyog yuav tsum xaiv cov khoom noj pellet rau kev tshuaj xyuas zoo.
2.3 Cov Qauv thiab cov txheej txheem ntawm kev tshuaj xyuas zoo
2.3.1 Qib gelatinization ntawm cov hmoov txhuv nplej siab
Thaum kuaj qhov degree gelatinization ntawm cov hmoov txhuv nplej siab hauv cov qauv pub pellet, cov neeg ua haujlwm tuaj yeem siv amylase los ntes nws. Ntxiv amylase rau cov hmoov txhuv nplej siab, thiab xam qhov tshuaj tiv thaiv ntawm amylase thiab cov hmoov txhuv nplej siab. Thaum kawg, ntxiv cov kua iodine, thiab txiav txim siab qhov degree ntawm cov hmoov txhuv nplej siab gelatinization los ntawm kev soj ntsuam qhov tob ntawm cov tshuaj tiv thaiv.
2.3.2 Qhov tawv ntawm cov khoom noj pellets
Yuav kom paub tseeb tias cov khoom noj pellet zoo, yuav tsum tau kuaj xyuas nws qhov nyuaj. Tus qauv nyuaj ntawm cov khoom noj pellet yuav tsum xa mus rau cov ntaub ntawv tseem ceeb.
2.3.3 Kev kam rau siab ntawm cov khoom noj pellet
Muab cov khoom noj pellet tso rau hauv lub thawv tig thiab tig nws ntawm 50r / min rau 20 feeb. Tom qab nres, tshem tawm cov khoom noj pellet thiab tom qab ntawd hnyav qhov hnyav seem ntawm cov khoom noj pellet thiab qhia nws hauv m.
3. cov txiaj ntsig ntawm kev xeem
3.1 Qhov cuam tshuam ntawm qhov zoo ntawm cov khoom noj, qhov kub thiab qhov loj ntawm lub qhov rau qhov zoo thiab qhov tawv ntawm cov khoom noj pellet. Qhov kev sim no feem ntau kawm txog qhov kev hloov pauv ntawm qhov zoo ntawm cov khoom noj pellet hauv qhov kub qis. Cov khoom siv tseem ceeb suav nrog pob kws, hmoov taum pauv, thiab lwm yam, uas raug ua tiav thiab laus. Tom qab ntawd, nws raug granulated ntawm qhov kub qis. Nws pom tias qhov zoo ntawm cov khoom noj pellet tsis yog tsuas yog cuam tshuam los ntawm qhov sib piv ntawm cov khoom siv raw, tab sis kuj los ntawm qhov loj ntawm lub qhov tuag ntawm lub tshuab ua haujlwm. Thaum qhov kub ntawm kev tsim cov khoom noj pellet siab dua, qhov piv rau qhov loj thiab ntev ntawm lub qhov membrane ntawm lub tshuab loj dua, thiab qhov tawv ntawm cov khoom noj pellet tsim tawm siab dua, tab sis nws yuav cuam tshuam rau kev ua haujlwm ntawm probiotics hauv cov khoom noj, thiab lub zog siv hauv kev tsim cov khoom noj pellet kuj yuav nce ntxiv raws li. Cov txiaj ntsig ntawm kev sim qhia tau hais tias txhawm rau kom ntseeg tau tias qhov zoo ntawm cov khoom noj pellet tsim tawm mus txog tus qauv, nws yuav tsum tau tsim tawm hauv cov xwm txheej tsim khoom zoo li no.
3.2 Qhov cuam tshuam ntawm qhov kub thiab qhov loj ntawm lub qhov tuag rau qib gelatinization ntawm cov hmoov txhuv nplej siab hauv cov khoom noj pellet. Tom qab ntau qhov kev tshawb fawb sim, pom tau tias qhov kub thiab qhov loj ntawm lub qhov tuag muaj feem cuam tshuam loj heev rau qib gelatinization ntawm cov hmoov txhuv nplej siab hauv cov khoom noj pellet. Nyob rau hauv tib qho kub, qhov me dua ntawm lub qhov tuag, qhov cuam tshuam ntau dua rau qib gelatinization ntawm cov hmoov txhuv nplej siab hauv cov khoom noj pellet.
3.3 Qhov cuam tshuam ntawm qhov kub thiab qhov sib piv ntawm qhov loj ntawm lub qhov tuag thiab qhov ntev ntawm cov probiotics nyob rau hauv cov granules. Tom qab ntau qhov kev sim, pom tias qhov kub thiab txias cuam tshuam rau kev ua haujlwm ntawm probiotics. Yog tias qhov kub thiab txias siab dhau thaum lub sijhawm tsim cov khoom noj pellet, nws yuav txo qhov kev ua haujlwm ntawm probiotics. Yog li ntawd, txhawm rau kom ntseeg tau tias cov probiotics khaws cia thaum lub sijhawm tsim cov khoom noj pellet thiab cov qauv kev xeem zoo ntawm cov khoom noj pellet, nws yog qhov tsim nyog los tsim cov khoom noj pellet hauv qab qhov kub qis.
4. Xaus Lus
Los ntawm qhov kev sim no, nws tuaj yeem pom tias qhov zoo, qhov nyuaj thiab tus lej ntawm probiotics hauv cov khoom noj pellet tsis yog tsuas yog cuam tshuam los ntawm qhov kub thiab txias ntawm cov khoom tsim tawm, tab sis kuj los ntawm txoj kab uas hla ntawm lub qhov tuag. Los ntawm ntau qhov kev tshawb fawb, nws tau pom tias kev siv cov khoom siv raw khoom rau kev tsim cov khoom noj pellet hauv qab qhov kub qis yog qhov zoo rau kev txhim kho qhov zoo thiab qhov nyuaj ntawm cov khoom noj pellet; nyob rau hauv tib lub kub thiab txias, qhov siab dua qhov sib piv ntawm txoj kab uas hla ntawm lub qhov tuag, qhov zoo dua ntawm kev tsim cov pellets. Lub zog siv hauv cov txheej txheem pub mis yog siab dua. Los ntawm kev sim, nws tau pom tias qhov kev daws teeb meem zoo tshaj plaws rau kev tsim cov khoom noj pellet yog siv cov khoom siv nrog lub qhov tuag txoj kab uas hla ntawm 6: 1 ntawm qhov kub ntawm 65 ° C los tsim cov khoom noj pellet ntawm qhov zoo tshaj plaws.
