Kev khaws cia ginseng yog ib qho kev cov nyom rau ntau tus neeg siv khoom vim nws muaj ntau cov suab thaj, uas ua rau nws yooj yim nqus dej noo, pwm loj hlob, thiab kab tsuag, yog li cuam tshuam rau nws cov txiaj ntsig kho mob. Ntawm cov txheej txheem ua ginseng, cov txheej txheem ziab ib txwm muaj feem ntau ua rau poob qhov ua tau zoo ntawm tshuaj thiab tsis zoo nkauj. Qhov sib piv, ginseng ua tiav nrog lub tshuab ziab khov-qhuav tuaj yeem khaws nws cov khoom xyaw nquag, suav nrog cov khoom sib xyaw xws li ginsenosides, yam tsis poob. Cov khoom ua tiav li no, feem ntau hu ua "active ginseng," muaj cov tshuaj sib xyaw ua ke ntau dua."OB LEEG" Kev Qhuav Khov, ua ib lub tuam txhab muab kev pabcuam ziab khov hauv lub tshuab nqus tsev, tau ua kev tshawb fawb tob txog cov txheej txheem ziab ginseng thiab lub hom phiaj yog los pab cov kws tshawb fawb ua cov haujlwm ziab khov kom zoo dua.
1. Yuav ua li cas teeb tsa Eutectic Point thiab Thermal Conductivity ntawm Ginseng
Ua ntej pib txoj kev ua kom qhuav khov, nws yog ib qho tseem ceeb kom txiav txim siab qhov eutectic point thiab thermal conductivity ntawm ginseng, vim tias cov yam no yuav cuam tshuam rau qhov chaw teeb tsa ntawm lub tshuab ziab khov. Raws li Arrhenius (SA Arrhenius) ionization theory thiab kev sim los ntawm ntau tus kws tshawb fawb, qhov kub ntawm eutectic point rau ginseng pom tias nyob nruab nrab ntawm -10 ° C thiab -15 ° C. Thermal conductivity yog ib qho tseem ceeb rau kev xam cov khoom siv txias, lub zog cua sov, thiab lub sijhawm ziab. Vim tias ginseng muaj cov qauv porous zoo li honeycomb, nws tuaj yeem kho tau ua cov khoom porous, thiab txoj kev conduction cua sov ruaj khov-state tuaj yeem siv los ntsuas nws cov thermal conductivity. Hauv kev tshawb fawb txog kev ziab khov uas tau ua los ntawm Xibfwb Xu Chenghai ntawm Northeastern University, nws tau pom tias thermal conductivity ntawm ginseng yog 0.041 W / (m · K) siv cov mis xam cua sov thiab kev ua haujlwm sim.
2. Cov Ntsiab Lus Tseem Ceeb hauv Cov Txheej Txheem Khov-Qhuav Ginseng
"OB LEEG" Kev Qhuav Khov piav qhia txog cov txheej txheem qhuav ginseng ua ntej kho, ua ntej khov, ziab sublimation, ziab desorption, thiab tom qab kho. Cov txheej txheem no zoo ib yam li ntau lwm yam tshuaj ntsuab. Txawm li cas los xij, muaj ntau yam ntsiab lus uas yuav tsum tau them sai sai. Kev Qhuav Khov Plaub-ring pom zoo kom ntxuav ginseng ua ntej ziab, ua kom nws zoo, thiab xaiv cov hauv paus ginseng uas muaj cov kab uas zoo sib xws. Muab cov koob nyiaj tso rau ntawm qhov chaw ntawm ginseng thaum lub sijhawm ua. Kev npaj no tuaj yeem pab ua kom qhuav ntau dua, txo lub sijhawm ziab, thiab ua rau ginseng qhuav zoo nkauj dua.
Kub thiab Txias Thaum Lub Caij Ua Ntej Khov
Nyob rau theem ua ntej khov, qhov kub ntawm ginseng lub eutectic point yog li ntawm -15°C. Lub tshuab ziab khov yuav tsum tswj qhov kub ntawm lub txee ntawm 0°C txog -25°C. Yog tias qhov kub siab dhau, qhov chaw ntawm ginseng yuav tsim cov npuas, ntsws, thiab lwm yam teeb meem uas cuam tshuam rau cov txiaj ntsig ntawm kev sim. Lub sijhawm ua ntej khov nyob ntawm lub taub ntawm ginseng thiab kev ua haujlwm ntawm lub tshuab ziab khov. Yog tias siv lub tshuab ziab khov tsim nyog, txo ginseng ntawm qhov kub hauv chav mus rau li ntawm -20°C thiab teeb tsa lub sijhawm ua ntej khov rau 3-4 teev yuav ua rau muaj txiaj ntsig zoo tshaj plaws.
"OB OB" Freeze Drying muaj ntau yam khoom siv sim ua kom khov uas tuaj yeem pab cov kws tshawb fawb ua tiav cov txiaj ntsig zoo ua ntej khov. Piv txwv li, lub tshuab khov "OB OB" PFD-50 muaj qhov kub tsawg kawg nkaus ntawm -75°C, thiab nws qhov txias ntawm lub txee tuaj yeem poob ntawm 20°C mus rau -40°C hauv qab 60 feeb. Qhov txias ntawm lub qhov txias tuaj yeem poob ntawm 20°C mus rau -40°C hauv qab 20 feeb. Qhov kub ntawm lub txee yog ntawm -50°C thiab +70°C, nrog rau lub peev xwm sau dej ntawm 8KG.
Yuav Ua Li Cas Thaum Lub Sijhawm Sublimation Drying Kom Tsis Txhob Ua Tsis Tau Zoo
Kev ziab ginseng los ntawm sublimation yog ib qho txheej txheem nyuaj uas xav tau kev cua sov tas mus li rau qhov kub sublimation latent thaum xyuas kom meej tias qhov kub ntawm qhov sublimation interface tseem nyob hauv qab eutectic point. Thaum lub sijhawm no, yuav tsum tau ua tib zoo saib xyuas kom qhov kub ntawm cov ginseng khov-qhuav ntawm lossis qis dua qhov kub collapse, uas suav tias yog nyob ib puag ncig -50 ° C. Yog tias qhov kub siab dhau, cov khoom yuav yaj thiab pov tseg. Yuav kom ntseeg tau tias ziab du, kev tswj hwm qhov kub nkag thiab qhov kub ntawm ginseng yog qhov tsim nyog kom tsis txhob ua tsis tiav ntawm kev sim. Lub sijhawm kuj yog ib qho tseem ceeb, thiab kev tshawb fawb qhia tias kev teeb tsa lub sijhawm ziab sublimation ntawm 20 txog 22 teev yuav ua rau muaj txiaj ntsig zoo tshaj plaws.
Nrog "OB LUB" cov tshuab ziab khov, cov neeg ua haujlwm tuaj yeem nkag mus rau cov kev teeb tsa ziab khov rau hauv cov khoom siv, ua rau hloov mus rau kev ua haujlwm tes tiag tiag. Cov ntaub ntawv ziab khov tuaj yeem saib xyuas, thiab cov kev teeb tsa hloov kho txhua lub sijhawm thaum lub sijhawm ua haujlwm. Lub kaw lus kuj tseem saib xyuas, nrhiav pom, thiab sau cov ntaub ntawv tseem ceeb, nrog rau cov yam ntxwv xws li kev ua haujlwm ceeb toom tsis siv neeg thiab cov peev xwm yaj khov kom ntseeg tau tias cov txiaj ntsig ziab khov zoo tshaj plaws.
Kev Tswj Xyuas Lub Sijhawm Qhuav Kom Qhuav Mus Txog Li 8 Teev
Tom qab ziab sublimation, cov phab ntsa capillary ntawm ginseng tseem muaj cov dej noo uas yuav tsum tau tshem tawm. Cov dej noo no xav tau cua sov txaus rau kev tshem tawm. Hauv theem ziab desorption, qhov kub ntawm cov khoom siv ginseng yuav tsum tau tsa mus rau qhov siab tshaj plaws ntawm 50 ° C, thiab lub chamber yuav tsum tswj lub tshuab nqus tsev siab kom tsim qhov sib txawv ntawm lub siab los pab kom cov dej pa dej ua pa. "OB LEEG" Freeze Drying pom zoo kom tswj lub sijhawm ziab desorption mus txog li 8 teev.
Kev kho mob tom qab Ginseng raws sijhawm
Kev kho ginseng tom qab ziab yooj yim heev. Tom qab ziab lawm, yuav tsum tau kaw lub tshuab nqus tsev tam sim ntawd los yog siv nitrogen purged. "OB LEEG" Kev ziab khov ceeb toom cov neeg siv tias ginseng muaj dej noo ntau tom qab ziab, yog li cov neeg ua haujlwm yuav tsum tiv thaiv nws kom tsis txhob nqus dej noo thiab lwj. Ib puag ncig hauv chav kuaj yuav tsum khaws cia kom qhuav.
Cov ginseng uas siv lub tshuab ziab kom qhuav zoo dua li cov ginseng uas ziab los ntawm cov txheej txheem ib txwm muaj xws li ginseng liab lossis ginseng ziab hnub. Qhov no yog vim tias cov ginseng uas siv tau qhuav thaum kub tsawg, khaws nws cov enzymes, ua rau nws yooj yim zom thiab nqus tau, thiab khaws nws cov khoom siv tshuaj. Ntxiv mus, nws tuaj yeem rov ua kom qhuav dua los ntawm kev tsau rau hauv cawv tsawg lossis dej lim.
Thaum kawg, "OB LEEG" Kev Khov Qhuav ceeb toom rau txhua tus tias kev ua cov ginseng ntawm ntau qhov loj me thiab siv cov tshuab ziab khaub ncaws sib txawv yuav ua rau muaj qee qhov sib txawv ntawm cov kab nkhaus ziab khaub ncaws. Thaum lub sijhawm sim, nws yog ib qho tseem ceeb kom nyob twj ywm, tshuaj xyuas qhov xwm txheej tshwj xeeb, kho cov kev ntsuas ziab khaub ncaws, txhim kho qhov ceev ziab, thiab xyuas kom meej tias cov txiaj ntsig ziab khaub ncaws zoo tshaj plaws.
Lub tshuab ziab khov zoo muab qhov kub thiab txias ruaj khov, nqus tsev, thiab cov dej noo, ua kom muaj kev faib tawm ntawm cov cua sov thiab cov khoom hnyav thaum lub sijhawm ziab khov, yog li txhim kho kev ziab kom zoo thiab cov khoom zoo. Tsis tas li ntawd, qhov zookhov lub tshuab ziab khaub ncawstuaj yeem txo kev siv hluav taws xob thiab cov nqi hauv kev sim tshawb fawb, lav qhov khoom kawg zoo li cas thiab zoo. Ua ib lub tuam txhab muab kev pabcuam ziab khov hauv lub tshuab nqus tsev, "BOTH" Freeze Drying tshwj xeeb hauv kev muab cov qauv tsim ziab khov ua haujlwm siab thiab cov kev daws teeb meem ziab khov hauv lub tshuab nqus tsev, phim cov kev xav tau ntawm cov khoom ziab khov sib txawv. Cov neeg ua haujlwm tshaj lij ntawm "BOTH" Freeze Drying mob siab rau kev muab cov lus qhia ua haujlwm kom ntxaws thiab cov kws tshaj lij los pab txhua tus neeg ua haujlwm kom ua tiav sai, txhim kho kev tshawb fawb thiab kev ua haujlwm zoo.
