Nrog rau kev loj hlob ntxiv hauv kev lag luam xav tau rau khov- zaub qhuav, ntau yam thiab cov khoom zoo tau dhau los ua qhov tsis sib xws. Rau cov neeg tau txais kev pab thiab cov neeg yuav khoom, kev paub txog cov txheej txheem kev txheeb xyuas tau zoo tuaj yeem paub qhov txawv ntawm qhov tseeb thiab cuav khov - zaub qhuav, thiab nruab nrab ntawm - cov khoom zoo thiab tsis zoo, yog li ua kom muaj kev nyab xeeb thiab cov txiaj ntsig kev noj haus.
Ua ntej, pib nrog cov txheej txheem thev naus laus zis thiab cov ntaub ntawv sau npe. Kev khov tiag tiag- cov zaub qhuav yuav tsum tau qis dua - qhov kub thiab txias thiab lub tshuab nqus tsev sublimation lub cev qhuav dej. Lub ntim yuav tsum qhia meej meej tias "khov-qhuav" lossis "freeze-qhuav" thiab piav qhia luv luv txog cov txheej txheem txheej txheem. Yog tias nws tsuas yog daim ntawv lo "qhuav" lossis "ua kom qhuav cua kub," nws yog cov khoom siv lub cev qhuav dej, thiab nws cov qauv ntawm cov ntaub so ntswg thiab cov khoom noj khoom haus zoo sib txawv los ntawm khov- cov khoom qhuav. Tsis tas li ntawd, cov khoom lag luam raug cai yuav tsum muaj daim ntawv tso cai ntau lawm, cov qauv siv, thiab cov ntsuas ntsuas tsim nyog kom yooj yim traceability thiab xyuas kom meej.
Qhov thib ob, saib xyuas qhov tsos thiab cov yam ntxwv ntawm cov ntaub ntawv. High- khov khov zoo- cov zaub qhuav yog plump thiab txhais tau meej meej, nrog cov xim ze rau lub ntuj xim ntawm cov khoom siv raw, tsis muaj qhov pom tseeb xim av, xim dub, lossis xim dawb - zoo li cov muaju. Vim lawv cov qauv ntxeem tau, lawv hnov lub teeb thiab nkig, yooj yim crumbling nrog lub teeb siab tab sis tsis tig mus rau hauv hmoov. Cov khoom lag luam tsis zoo feem ntau nthuav tawm shrinkage, deformation, dull xim, thiab txawm tias impurities vim cov khoom tsis zoo los yog ua tsis zoo. Ib qho qauv me me tuaj yeem muab tso rau ntawm daim ntawv dawb thiab tapping me ntsis; khov tiag tiag- cov zaub qhuav yuav tsim cov khoom sib xws yam tsis muaj roj seem.
Thib peb, sim ua kom rov ua kom dej yooj yim. Tsau cov qauv hauv 40-50℃dej sov. High- khov khov zoo- cov zaub qhuav yuav rov ua dej tsis pub dhau feeb, rov qab mus rau lawv qhov loj thiab cov duab qub, nrog rau kev sib tw zoo nkauj thiab lub ntuj aroma. Cov khoom cuav lossis cov khoom tsis zoo tsis zoo- cov khoom qhuav qhuav rov qab maj mam, yooj yim ua mos thiab muag muag, lossis tseem nyuaj txawm tias tom qab ntub dej ntev, nrog rau qhov tsw qab lossis tsw qab, qhia cov qauv ntawm tes thiab cov khoom puas.
Thaum kawg, xyuas cov khoom xyaw thiab cov ntawv pov thawj. Cov khoom uas tsis muaj qab zib ntxiv, ntsev, tshuaj tua kab mob, lossis cov xim cuav yog nyiam, thiab cov npe ntawm cov khoom xyaw yuav tsum yog qhov tseeb. Muaj cov ntawv tso cai tsim khoom SC, ISO lossis HACCP cov ntawv pov thawj, thiab cov ntawv pov thawj suav suav thiab cov ntawv pov thawj tshuaj xyuas rau cov khoom tuaj yeem tuaj yeem ua pov thawj ntseeg tau.
Los ntawm kev siv cov txheej txheem saum toj no, qhov tseeb thiab qhov zoo ntawm khov- cov zaub qhuav tuaj yeem raug txheeb xyuas tau tseeb thaum lub sijhawm kev yuav khoom thiab kev lees paub, tiv thaiv cov neeg siv khoom txoj cai thiab txhawb kev tsim kho tus qauv ntawm kev lag luam.
