1. Nrog rau qhov tshwm sim ntawm lub sijhawm tsis muaj tshuaj tua kab mob, cov khoom siv hluav taws xob zoo li probiotics tau maj mam ntxiv rau pellet pub. Yog li ntawd, thaum lub sij hawm pub khoom noj, qhov kub thiab txias kuj tseem yuav cuam tshuam rau qhov zoo ntawm pellet feeds. Yog tias qhov kub thiab txias siab dhau thaum lub sij hawm tsim cov pellet pub, nws yuav tua cov khoom kub-rhiab heev xws li probiotics. Yog tias qhov kub thiab txias qis dhau, cov kab mob hauv cov khoom noj pellet yuav tsis ua kom tsis muaj menyuam, ua rau cov khoom noj pellet. Qhov zoo yog substandard. Yog li ntawd, txhawm rau zam qhov cuam tshuam ntawm qhov ntsuas kub ntawm qhov ntsuas, qhov kev sim no yog los kawm txog qhov cuam tshuam ntawm qhov kub thiab txias qhov sib piv ntawm qhov ua tau zoo ntawm pellet pub nyob rau hauv qhov kub thiab txias, thiaj li kawm txog kev tsim cov pellets. pellet pub nyob rau hauv cov xwm txheej zoo tom qab cov ntaub ntawv raw yog matured. Seb nws yog tag nrho thiab seb nws puas ua tau raws li cov qauv rau kev kuaj particle zoo. Lub hom phiaj tseem ceeb ntawm qhov kev sim no yog muab qee qhov kev qhia theoretical rau kev tsim cov tsiaj txhu pellet pub.
2.1 Cov khoom xyaw tseem ceeb ntawm kev sim cov khoom noj thiab cov pellet raw cov ntaub ntawv muaj xws li: pob kws, ntses noj, ntsev, methionine, threonine, thiab lwm yam. Cov pob kws yuav tsum tau crushed rau hauv 11.0mm nplua particles, thiab ces cov raw khoom yog proportioned raws li cov khoom noj khoom haus. xav tau, thiab ces matured. Tom qab txias, cov khoom kub-rhiab xws li probiotics tau ntxiv, thiab thaum kawg tempered rau hauv hais. Qhov kub thiab txias ntawm cov khoom noj pellets feem ntau yog 60, 50, 40, thiab 30 ° C, thiab qhov ntev thiab txoj kab uas hla ntawm lub qhov tuag feem ntau yog 7: 1, 6: 2, thiab 10: 1, thiab 300 mg / kg ntawm probiotic. cov tshuaj yog ntxiv raws li cov ntaub ntawv xeem. , thiab qhov kub ntawm cov pellet pub kuj yuav tsum tau tempered los tiv thaiv cov kev ua ntawm probiotics. Tsis tas li ntawd, qee cov vitamins yuav tsum tau ntxiv rau txhua kilogram ntawm pellet pub kom paub meej tias cov khoom noj khoom haus ntawm cov pellet pub tuaj yeem ua tau raws li lub teb chaws cov cai.
2.2 Sampling thiab sau cov qauv
Txhawm rau kom ntseeg tau tias cov khoom noj pellet tsim tau tsim nyog, tom qab tsim cov pellet pub, nws yog ib qho tsim nyog yuav tau xaiv cov pellet pub rau kev soj ntsuam zoo.
2.3 Cov qauv thiab cov txheej txheem ntawm kev tshuaj xyuas zoo
2.3.1 Gelatinization degree ntawm starch
Thaum kuaj cov gelatinization degree ntawm cov hmoov txhuv nplej siab hauv cov qauv pub pellet, cov neeg ua haujlwm tuaj yeem siv amylase los kuaj xyuas nws. Ntxiv amylase rau cov hmoov txhuv nplej siab, thiab suav cov tshuaj tiv thaiv ntawm amylase thiab starch. Thaum kawg, ntxiv cov tshuaj iodine, thiab txiav txim siab qib ntawm cov hmoov txhuv nplej siab gelatinization los ntawm kev soj ntsuam cov xim tob ntawm cov tshuaj tiv thaiv.
2.3.2 Hardness ntawm pub pellets
Txhawm rau ntsuas qhov zoo ntawm pellet pub, nws qhov hardness kuj yuav tsum tau kuaj. Tus qauv hardness ntawm pellet pub yuav tsum xa mus rau cov ntaub ntawv tseem ceeb.
2.3.3 Tolerance Performance index ntawm pellet pub
Muab cov pellet pub rau hauv lub thawv teb thiab tig nws ntawm 50r / min rau 20 feeb. Tom qab nres, tshem tawm cov pellet pub thiab ntsuas qhov seem ntawm cov pellet pub thiab nthuav tawm hauv m.
3. cov ntawv xeem
3.1 Kev cuam tshuam ntawm cov khoom noj zoo, qhov kub thiab qhov taub qhov sib piv ntawm qhov zoo thiab hardness ntawm pellet pub. Qhov kev sim no tsuas yog kawm txog kev hloov pauv ntawm pellet pub zoo nyob rau hauv qhov kub thiab txias. Cov khoom siv tseem ceeb muaj xws li pob kws, taum noj mov, thiab lwm yam, uas tau ua tiav thiab matured. Tom qab ntawd, nws yog ces granulated ntawm qis kub. Nws tau pom tias qhov zoo ntawm pellet pub tsis yog tsuas yog cuam tshuam los ntawm kev faib ua feem ntawm cov ntaub ntawv raw, tab sis kuj los ntawm txoj kab uas hla ntawm qhov tuag qhov ntawm lub tshuab ua. Thaum qhov kub ntawm kev tsim cov pellet pub ntau dua, qhov sib piv rau txoj kab uas hla thiab qhov ntev ntawm lub qhov membrane ntawm lub tshuab yog qhov loj dua, thiab qhov hardness ntawm cov khoom noj pellet ua tau ntau dua, tab sis nws yuav cuam tshuam rau kev ua ntawm probiotics hauv cov khoom noj, thiab lub hwj chim noj nyob rau hauv tsim pellet pub yuav kuj yuav nce raws li. Cov txiaj ntsig kev sim qhia tau hais tias txhawm rau kom ntseeg tau tias qhov zoo ntawm cov khoom noj pellet uas tsim tau ncav cuag tus qauv, nws yuav tsum tau tsim nyob rau hauv cov xwm txheej zoo li no.
3.2 Qhov cuam tshuam ntawm qhov kub thiab txias qhov taub ntawm qhov gelatinization degree ntawm cov hmoov txhuv nplej siab hauv pellet pub. Tom qab ib tug series ntawm kev soj ntsuam kev tshawb fawb, nws tau pom hais tias cov neeg kho tshuab txias txias thiab tuag qhov taub muaj ib tug tseem ceeb heev cuam tshuam rau cov starch gelatinization degree ntawm pellet pub. Nyob rau hauv tib qhov kub thiab txias, qhov me me ntawm txoj kab uas hla ntawm lub qhov tuag, qhov ntau dua qhov cuam tshuam ntawm gelatinization degree ntawm starch nyob rau hauv pellet pub.
3.3 Qhov cuam tshuam ntawm tempering kub thiab tuag qhov taub txoj kab uas hla mus rau qhov ntev piv ntawm qhov tuav qib ntawm probiotics hauv cov granules. Tom qab kev sim ntau, nws tau pom tias cov haujlwm ntawm probiotics cuam tshuam rau qhov kub thiab txias. Yog tias qhov kub thiab txias dhau thaum lub sij hawm tsim cov pellet pub, nws yuav ncaj qha txo cov kev ua ntawm probiotics. Yog li ntawd, txhawm rau txhawm rau txhawm rau khaws cov tshuaj probiotics thaum lub sijhawm tsim cov pellet pub thiab cov qauv ntsuas zoo ntawm cov pellet pub, nws yog ib qho tsim nyog los tsim cov pellet pub nyob rau hauv qhov kub thiab txias.
4. Cov lus xaus
Los ntawm qhov kev sim no, nws tuaj yeem pom tias qhov zoo, hardness thiab tus naj npawb ntawm probiotics hauv pellet pub tsis tsuas yog cuam tshuam los ntawm qhov kub thiab txias, tab sis kuj los ntawm txoj kab uas hla ntawm lub qhov tuag. Los ntawm kev tshawb fawb ntau, nws tau pom tias siv cov ntaub ntawv paub tab rau kev tsim cov pellet pub nyob rau hauv qhov kub thiab txias yog qhov tsim nyog rau kev txhim kho qhov zoo thiab hardness ntawm pellet pub; nyob rau hauv tib qhov kub thiab txias, qhov siab dua qhov tuag qhov taub qhov sib piv, qhov zoo dua ntawm 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 pellet pub yog siv cov khoom siv nrog lub qhov tuag qhov sib piv ntawm 6: 1 ntawm qhov kub ntawm 65 ° C los tsim cov khoom noj pellet zoo tshaj plaws.
