pub grain tawv, ua raws nraim li 433 tus cai ntawm cov qauv tsim thiab cov txheej txheem.
Tsuas hais tau tias , ib qho kev xav tau yuav tsum hloov cov mis, cov khoom siv lub cev thiab tshuaj ntawm cov ntaub ntawv, cov txheej txheem tsis tau txiav txim siab hauv peb cheeb tsam, txhua tus uas tau lees paub txog 40%, 30%, 30%, uas yog cov khoom noj tiav.
Cov nyhuv ntawm qhov kev ua tau zoo yog feem ntau pom nyob rau hauv cov khoom sib haum, cov qauv yuav tsum paub txog kev sib txawv quenching thiab cov txheej txheem kev siv lub cev thiab tshuaj ntawm cov ntaub ntawv, formulation tsim nws tus kheej yuav tsum txiav txim siab rau qhov kev ua piv txwv txog morphology thiab particle khoom; feem ntau ntawm cov neeg tau txais kev pabcuam hauv lub tuam txhab tau pom daim ntawv tso cai muab tso tawm, cov ntaub ntawv nyuab nyiab tsis ua li cas. Hauv qhov kev sib tham, cov txheej txheem formulation tsis siv yuav tsum muaj xws li: qhov zoo tshaj plaws, pwm coefficient, qhov muaj peev xwm, thiab lwm yam, thiab feem ntau yog muaj feem xyuam nrog cov zoo tshaj qhov zoo sib xws ntawm cov granulation, cov degree ntawm lub cev ntawm cov txheej txheem ntawm cov pellets yog 40%.
Cov khoom hloov nyob rau hauv lub cev thiab tshuaj: cov qauv formulator feem ntau ignored los yog ib sab, piv txwv, gelatinization kub ntawm cov khoom raw, thermal kub, shear zog, txheej txheem hloov; Piv txwv: pre-gelatinized maize universal tseem ceeb kub ntawm 75 degrees, quenching kub tshaj 75 mus 76 degrees, yuav ua tau ntau ntau ntxiv nyob rau hauv cov degree ntawm polenta, yuav ua rau kom qhov hardness ntawm cov khoom loj tuaj; thiab cov qoob noob uantej twb yuav tsum tau tsa kom sov siab dua 86 degrees yuav ua kom muaj cov nyhuv zoo dua qub, thiab qhov sib txawv ntawm cov dej kub qis dua 86 degrees, tab sis kom tau ib cov neeg xoob. Txhawm kom txhim kho cov txiaj ntsim ntawm cov granulation, feem ntau ntxiv thaum lub sij hawm noj ntau phospholipids, kuj ua rau cov khoom sib tsoo ntawm gelatinized starch; thiab cov feem ntawm cov ntaub ntawv hloov nyob rau hauv ntau lawm, qhov feem ntawm cov granulation yog li 30%.
T tsis paub meej: nws yog hais txog kev tuav cov khoom me me, kev tso pa tawm, kev kub quenching, lub sij hawm, lub nplhaib ntawm lub nplhaib, qhov sib txuam ntawm kev sib hloov, thiab kev sib piv ntawm lawv thiab cov zoo li; zoo li cov khoom faib tawm, muaj thaj tsam loj dua, tab sis kuj tom qab muab cov khoom muaj ntau daim ntawv cog lus, feem ntau khaus pob kws tom qab ib lub zog ua rau cov khoom sib zog ntau dua. Qhov me me lub nplhaib ntawm lub nplhaib, lub nplhaib pwm tuaj ntawm kev sib txhuam cov khoom tsis sib haum xeeb, qhov ntau dua qhov sib txov zog kuj ua rau ntau qhov nyuaj nyuaj, tsis nplhaib tuag compression ratio uas tuaj yeem siab sawv cev; nyob rau hauv raws li kev siv ntawm lub nplhaib pwm, lub zog ntawm granulation yog txog 30%.
Ntau tshaj 433 txoj cai , tsuas yog nruab nrab ntawm rooj plaub dav dav, tsis yog txhua tus mob yog tib yam; vim tias cov khoom hloov hauv ib qho ntawm cov kev cai tshwj xeeb yuav ua rau muaj kev cuam tshuam txog cov granulation, xws li cov ntaub ntawv tsis txaus ntseeg, vim tsis muaj pwm ua rau hauv lub nplhaib granulation txheej txheem kev sib txhuam tsis tau granulated thaiv cov teeb meem cav; Ntawm qhov kev sib tw, kev lag luam pub zaub mov ntawm cov cuab yeej ua zaub mov noj, tsis muaj kev cob qhia txog cov txheej txheem granulation, ntau ntawm kev paub, txawm muaj kev kawm ntau hom kev kawm tiav, thiab muaj kev nkag siab me ntsis txog cov khoom siv technology thiab kev tsim cov ntsiab lus thiab cov ntsiab lus.
