Kusungirako kwa ginseng kumakhala kovuta kwa ogula ambiri chifukwa ali ndi shuga wambiri, zomwe zimapangitsa kuti zizitha kuyamwa chinyezi, kukula kwa nkhungu, ndi tizilombo toyambitsa matenda, motero zimakhudza mtengo wake wamankhwala. Mwa njira zopangira ginseng, kuyanika kwachikhalidwe nthawi zambiri kumabweretsa kutaya kwamankhwala komanso mawonekedwe osawoneka bwino. Mosiyana ndi izi, ginseng yokonzedwa ndi chowumitsira chowumitsira vacuum imatha kusunga zinthu zomwe zimagwira ntchito, kuphatikiza zinthu zosasunthika monga ma ginsenosides, popanda kutayika. Zogulitsa zomwe zimakonzedwa motere, zomwe nthawi zambiri zimatchedwa "ginseng yogwira," zimakhala ndi zinthu zambiri zomwe zimagwira ntchito."ZOWIRI" Zowumitsa Azimitsa, monga katswiri wopereka ntchito zowumitsa zowumitsa zowuma, wachita kafukufuku wozama panjira yowumitsa madzi a ginseng ndipo cholinga chake ndi kuthandiza ofufuza kuti azitha kuyanika mozizira bwino.
1. Momwe Mungakhazikitsire Eutectic Point ndi Thermal Conductivity ya Ginseng
Musanayambe ntchito yowumitsa kuzizira, ndikofunikira kudziwa malo a eutectic ndi matenthedwe a ginseng, chifukwa izi zidzakhudza magawo a zowumitsira zowumitsira. Kutengera chiphunzitso cha ionization cha Arrhenius (SA Arrhenius) ndi kuyesa kwa asayansi osiyanasiyana, kutentha kwa eutectic point kwa ginseng kumapezeka pakati pa -10 ° C ndi -15 ° C. Thermal conductivity ndi gawo lofunikira pakuwerengera kuzirala, mphamvu yotenthetsera, ndi nthawi yowumitsa. Popeza ginseng ili ndi zisa zokhala ngati porous, imatha kutengedwa ngati porous, ndipo njira yokhazikika yotenthetsera kutentha ingagwiritsidwe ntchito kuyeza momwe amatenthera. Pakafukufuku wowumitsa kuzizira kochitidwa ndi Pulofesa Xu Chenghai ku yunivesite yaku Northeastern University, zidapezeka kuti matenthedwe a ginseng ndi 0.041 W/(m·K) pogwiritsa ntchito chilinganizo cha kutentha kwa kutentha ndi ntchito zoyesa.
2. Mfundo Zofunikira mu Njira Yowumitsa-Kuwumitsa kwa Ginseng
"ZOWIRI" Zowumitsa Zozizira zimafotokozera mwachidule njira yowumitsa-yimitse ya ginseng kuti isamalidwe, kuzizira, kuyanika kwa sublimation, kuyanika kwa desorption, ndi chithandizo pambuyo pake. Zimenezi n’zofanana ndi za zitsamba zina zambiri. Komabe, pali zambiri zomwe muyenera kuziganizira. Four-ring Freeze Drying imalimbikitsa kuyeretsa ginseng musanawumitse, kuyipanga bwino, ndikusankha mizu ya ginseng yokhala ndi ma diameter ofanana. Ikani singano zasiliva pamwamba pa ginseng panthawi yokonza. Kukonzekera kumeneku kungathandize kuyanika bwino, kuchepetsa nthawi yowumitsa, ndikupangitsa kuti ginseng yowumitsidwa ikhale yosangalatsa kwambiri.
Kutentha Koyenera Panthawi Yozizira Kwambiri
Mu gawo lozizira kwambiri, kutentha kwa ginseng kumakhala pafupifupi -15 ° C. Kutentha kwa shelefu ya zowumitsira kuyenera kuyendetsedwa pa 0°C mpaka -25°C. Ngati kutentha kuli kokwera kwambiri, pamwamba pa ginseng pakhoza kukhala thovu, kuchepa, ndi zina zomwe zimakhudza zotsatira za kuyesa. Nthawi yoziziritsa isanayambike zimatengera kukula kwa ginseng komanso momwe chowumitsira chowumitsira amaundana. Ngati mugwiritsa ntchito chowumitsira chowumitsira mufiriji choyenera, kutsitsa ginseng kuchokera ku firiji kupita ku -20 ° C ndikukhazikitsa nthawi yoziziritsa mpaka maola 3-4 kumabweretsa zotsatira zabwino.
"BOTH" Freeze Drying imapereka zowumitsira zingapo zoyesera zomwe zingathandize ofufuza kupeza zotsatira zabwino kwambiri zisanazizidwe. Mwachitsanzo, chowumitsira "BOTH" PFD-50 chowumitsa mufiriji chimakhala ndi kutentha kochepa kwa -75 ° C, ndipo kuzizira kwake kwa alumali kumatha kutsika kuchokera pa 20 ° C mpaka -40 ° C mkati mwa mphindi 60. Kuzizira kwa msampha kumatha kutsika kuchokera pa 20 ° C mpaka -40 ° C mkati mwa mphindi 20. Kutentha kwa alumali kumakhala pakati pa -50 ° C ndi +70 ° C, ndi mphamvu yosonkhanitsa madzi 8KG.
Momwe Mungagwiritsire Ntchito Panthawi Yoyanika Kutsitsa Kuti Mupewe Kulephera
Kuyanika kwa sublimation kwa ginseng ndi njira yovuta yomwe imafuna kutentha kosalekeza kwa kutentha kobisika kwa sublimation ndikuwonetsetsa kuti kutentha kwa mawonekedwe a sublimation kumakhalabe pansi pa eutectic point. Pochita izi, chidwi chapadera chiyenera kuperekedwa pakusunga kutentha kwa ginseng yowumitsidwa ndi kuzizira kapena pansi pa kutentha kwapang'onopang'ono, komwe kumawoneka kuti ndi -50 ° C. Ngati kutentha kuli kwakukulu kwambiri, mankhwalawa amasungunuka ndikuwonongeka. Kuonetsetsa kuti kuyanika bwino, kuwongolera bwino kutentha kwa kutentha ndi kutentha kwa ginseng ndikofunikira kuti mupewe kulephera kuyesa. Nthawi ndi chinthu chofunikira kwambiri, ndipo kafukufuku akuwonetsa kuti kuyika nthawi yowuma ya sublimation pakati pa maola 20 mpaka 22 kumabweretsa zotsatira zabwino.
Ndi "BOTH" zowumitsa zowumitsa, ogwiritsa ntchito amatha kuyika magawo owumitsa-owumitsa mu zida, zomwe zimathandizira kusintha kwanthawi yeniyeni kuti igwire ntchito pamanja. Deta yowumitsa kuzizira imatha kuyang'aniridwa, ndipo magawo amasinthidwa nthawi iliyonse panthawiyi. Dongosololi limayang'aniranso, kuzindikira, ndikulemba zomwe zili zofunika, zomwe zimakhala ndi ma alarm odziwikiratu komanso kuthekera kwa defrost kuwonetsetsa kuti zowumitsa zimawumitsidwa bwino.
Kuwongolera kwa Desorption Kuyanika Nthawi Kufikira Pafupifupi Maola 8
Pambuyo poyanika pansi, makoma a capillary a ginseng amakhalabe ndi chinyezi chomwe chiyenera kuchotsedwa. Chinyezichi chimafuna kutentha kokwanira kuti chiwonongeke. Mu gawo lowumitsa la desorption, kutentha kwa zinthu za ginseng kuyenera kukwezedwa mpaka 50 ° C, ndipo chipindacho chiyenera kukhala ndi vacuum yayikulu kuti pakhale kusiyana kwamphamvu kuti nthunzi wamadzi usasunthike. "ZOWIRI" Freeze Drying imalimbikitsa kuwongolera nthawi yowuma ya desorption mpaka pafupifupi maola 8.
Chithandizo cha Ginseng munthawi yake
Kuchiza kwa ginseng ndikosavuta. Pambuyo kuyanika, iyenera kutsukidwa nthawi yomweyo ndi vacuum-kusindikizidwa kapena kutsukidwa ndi nayitrogeni. "ZOWIRI" Zowumitsa Zozizira zimakumbutsa ogwiritsa ntchito kuti ginseng imakhala ndi hygroscopic ikaumitsa, kotero ogwiritsira ntchito ayenera kuiletsa kuti isamwe chinyezi ndikuwonongeka. Malo a labotale ayenera kukhala owuma.
Ginseng yogwira ntchito yokonzedwa ndi chowumitsira chowumitsira imakhala yabwinoko komanso mawonekedwe ake kuposa ginseng yowumitsidwa ndi njira zachikhalidwe monga red ginseng kapena ginseng youma ndi dzuwa. Izi ndichifukwa choti ginseng yogwira ntchito imakhala ndi madzi ochulukirapo pakutentha kotsika, kusunga ma enzymes ake, kupangitsa kuti ikhale yosavuta kugaya ndi kuyamwa, ndikusunga mankhwala ake. Kuphatikiza apo, imatha kubwezeretsedwanso m'malo ake atsopano poviika mu mowa wocheperako kapena madzi osungunuka.
Pomaliza, "ZOWIRI" Zowumitsa Zozizira zimakumbutsa aliyense kuti kukonza ma ginseng amitundu yosiyanasiyana ndikugwiritsa ntchito zowumitsa zowumitsa zoziziritsa kumapangitsa kuti pakhale kusiyanasiyana kopindika. Pakuyesako, ndikofunikira kukhalabe osinthika, kusanthula momwe zinthu zilili, kusintha magawo owumitsa-owuma, kuwongolera liwiro la kuyanika, ndikuwonetsetsa kuti zowumitsa zowuma zili bwino.
Chowumitsira bwino chowumitsira madzi chimapereka kutentha kosasunthika, vacuum, ndi condensation zotsatira, kuwonetsetsa kugawidwa kofanana kwa kutentha ndi kulemera panthawi yowuma, motero kumapangitsa kuyanika bwino ndi khalidwe lazogulitsa. Komanso khalidwekuzimitsa chowumitsirazitha kuchepetsa kugwiritsa ntchito mphamvu ndi ndalama pakuyesa kafukufuku, kutsimikizira mawonekedwe ndi mtundu wa chinthu chomaliza. Monga katswiri wopereka ntchito zowumitsa zowumitsa zowumitsa, "BOTH" Freeze Drying imagwira ntchito bwino kwambiri popereka zowumitsira zowumitsa zowuma bwino kwambiri komanso njira zowumitsa zowumitsa zowumira, zomwe zimagwirizana ndendende ndi zosowa za zida zosiyanasiyana zowumitsa. Gulu la akatswiri pa "BOTH" Freeze Drying ladzipereka kuti lipereke chitsogozo chokwanira komanso chaukadaulo kuti athandize wogwiritsa ntchito aliyense kuti afulumire mwachangu, kukonza kafukufuku ndi kupanga bwino.
