Khoom noj khoom haus khov tshuab ua haujlwm tseem ceeb hauv kev lag luam khoom noj niaj hnub. Nws tsis tsuas yog txuas ntxiv cov khoom noj txee lub neej tab sis tseem khaws cov khoom noj muaj txiaj ntsig ntau tshaj plaws thiab cov khoom qub. Ntawm ntau yam khoom siv khov nab kuab, tunnel freezers tau txais txiaj ntsig zoo hauv kev lag luam rau lawv cov kev ua tau zoo thiab kev ua haujlwm khov.
Kauj Ruam 1: Ntxuav zaub: Raws li ib qho tseem ceeb pretreatment ua ntej ceev khov, tu lub hom phiaj kom tshem tawm cov av saum npoo thiab impurities thaum txo cov kab mob microbial. Cov txheej txheem feem ntau suav nrog kev yaug dej thiab ntxuav npuas. Lub sijhawm thiab kev siv ntawm kev tu yuav tsum tau hloov kho raws li hom zaub kom tiv thaiv cov ntaub so ntswg puas. Tom qab- ntxuav, kev tshuaj ntsuam ua ntej yog ua los xyuas kom meej cov khoom zoo zoo ib yam rau kev ua haujlwm tom ntej.
Kauj Ruam 2: Txiav zaub: Cov kauj ruam no suav nrog kev txiav cov zaub kom huv si rau hauv me me los yog cov hlais uas tsim nyog rau kev khov sai, xav tau cov txheej txheem siab. Txoj kev txiav thiab qhov ntau thiab tsawg yog txiav txim siab los ntawm ntau hom zaub thiab cov ntaub ntawv khoom kawg. Kev txiav tsis tsuas yog txhim kho kev ua kom khov, tab sis tseem khaws cov zaub 'zoo li thiab kev ntxhib los mos tom qab khov.
Kauj Ruam 3: Blanching Treatment:Blanching siv luv luv-lub sij hawm siab-kub ua rau inhibit enzyme kev ua hauv zaub, tiv thaiv browning thiab tsw poob thaum lub sij hawm tom qab ua thiab cia. Kev tswj xyuas qhov kub thiab txias (feem ntau yog 80-90 degree) thiab ntev (ob peb vib nas this mus rau ob peb feeb) yuav tsum ua kom cov enzymes zoo yam tsis muaj kev cuam tshuam saj thiab cov as-ham.
Kauj Ruam 4: Ua kom txias thiab ntws tawm:Blanched zaub yuav tsum tau txias sai sai rau hauv chav tsev kub kom tsis txhob dhau - ua noj los ntawm qhov seem cua sov. Cov dej noo ntau dhau yog muab tshem tawm ntawm centrifugal dehydration lossis natural draining. Cov kauj ruam no yog qhov tseem ceeb rau kev khov tom ntej, vim tias cov dej noo ntau dhau ua rau cov dej khov loj uas ua rau cov nroj tsuag puas tsuaj.
Kauj Ruam 5: Pub rau hauv CBFI Tunnel Mesh Belt Freezer: Lub CBFI qhov mesh siv ceev lub freezer yog lub siab -cov cuab yeej ua tau zoo uas ua tiav qhov khov sai ntawm qhov qis - cua kub ntws. Txhawm rau kom tsis txhob khov tsis sib xws, cov kua txiv hmab txiv ntoo sib npaug sib npaug ntawm txoj siv conveyor yam tsis muaj stacking, uas thauj lawv mus rau hauv qhov dej khov rau qis - kub ceev khov.
Kauj Ruam 6: Cov txheej txheem ceev khov: Nyob rau hauv lub CBFI tunnel freezer, zaub yog raug kub tsis tshua muaj kub (feem ntau qis dua -30 degree), nrog rau lawv cov tub ntxhais kub poob sai heev hauv qab -18 degree. Qhov kev khov sai sai no ua rau tsim cov khoom me me, sib npaug ntawm cov dej khov hauv cov hlwb, txo cov phab ntsa ntawm tes thiab khaws cov qauv qub thiab cov khoom noj.
Kauj Ruam 7: Kev khaws cov khoom noj: Kev tsim cov dej khov me me yog qhov tseem ceeb ntawm kev siv tshuab ceev ceev. Los ntawm kev ua kom zoo tshaj qhov txias txias thiab qhov ntsuas kub, CBFI qhov lub freezer ua kom cov khoom noj muaj txiaj ntsig zoo tshaj plaws yam tsis muaj kev puas tsuaj rau cov qauv ntawm tes, txhim kho cov zaub khov zoo thiab ua tau raws li cov neeg siv khoom xav tau cov khoom noj qab haus huv thiab qab.
Qhov tsim ntawm cov dej khov me me ncaj qha txiav txim siab qhov zoo thiab cov khoom noj muaj txiaj ntsig ntawm cov zaub khov, ua haujlwm tseem ceeb ntawm cov txheej txheem khov sai. Nws tsim yog ze ze rau tus nqi khov thiab cov cuab yeej ua haujlwm, nrog rau cov txheej txheem tshwj xeeb raws li hauv qab no:
1. Kev hloov hauv Intracellular Water State: Nyob rau hauv chav tsev kub, dej nyob rau hauv cov zaub cell muaj nyob rau hauv ib tug kua lub xeev. Raws li qhov kub thiab txias, dej pib khov rau hauv dej khov. Kev khov qeeb qeeb ua rau cov dej nkag mus rau hauv cov dej khov loj, uas nyem thiab ua rau cov phab ntsa ntawm tes, ua rau cov khoom tsis zoo thiab cov khoom noj tsis zoo tom qab thawing.
2. Kev ua haujlwm nrawm nrawm: Kev khov sai sai ua tiav qhov ntsuas kub sai sai, inhibiting intracellular water migration thiab tsub zuj zuj, yog li tsim cov dej khov me me, zoo ib yam. Cov khoom siv lead ua no ua rau lub siab me me ntawm cov phab ntsa ntawm tes yam tsis muaj kev puas tsuaj rau cov qauv, ua kom tag nrho cov zaub ntawm daim ntawv qub, kev ntxhib los mos thiab cov as-ham.
3. Cov Lus Qhia Txog Kev Ua Haujlwm: Lub CBFI tunnel lub freezer ua kom lub cev txias ntawm cov zaub thiab sab hauv los ntawm kev ua kom huab cua khiav ceev thiab kev taw qhia. Lub caij no, qhov chaw kub tsis tshua muaj siab (qis dua -30 degree) ua kom cov txheej txheem khov, ua kom lub sij hawm luv rau cov dej khov siv lead ua thiab tiv thaiv kev loj hlob siv lead ua loj.
4. Cov teebmeem kawg: Lub tshuab ua kom khov nrawm no ua kom lub cev kub ntawm cov zaub hauv qab -18 degree, ua kom muaj cov dej khov me me. Nws tsis tsuas yog tswj hwm cov qauv ntawm tes kev ncaj ncees tab sis kuj ua kom cov khoom khaws cia ntawm cov khoom noj tseem ceeb xws li cov vitamins thiab minerals.
