Ibhanana yenye yeziqhamo esizitya rhoqo. Ukuze sigcine izakhamzimba kunye nombala wokuqala weemveliso ezicutshungulwayo zebhanana, abaphandi basebenzisaFi-reezeDi-ryer kwizifundo zokomisa nge-vacuum freeze. Uphando lokomisa nge-freeze kwiibhanana lugxile kakhulu kwizilayi zebhanana kunye nomgubo webhanana.
Inkqubo yokuqandisa i-banana powder ngokuyintloko ibandakanya amanyathelo aliqela: ukunyanga ngaphambi, ukuqandisa, ukomisa i-sublimation, ukomisa i-desorption, kunye nokupakishwa. Unyango lwangaphambi konyango lubandakanya ukuxobula, ukunqumla, kunye nokuxubha iibhanana ukuze kube lula ukomisa emva koko. Uqandisa ngaphambi konyango lubandakanya ukuqandisa i-banana pulp ukuya kubushushu obuthile ukuze kwenziwe ulungelelwano oluzinzileyo lwe-sublimation ngexesha lesigaba sokumisa i-sublimation. Uqandisa i-sublimation luquka ukufudumeza i-banana pulp eqandisiweyo phantsi kweemeko ze-vacuum ukususa umswakama nge-sublimation. Uqandisa i-desorption kususa umswakama oseleyo ukuze kufezekiswe ukoma okufunekayo. Ekugqibeleni, i-banana powder epakishiweyo ilungele ukuthengiswa.
Iiparameters ezibalulekileyo kufuneka zilawulwe ngokungqongqo ngexesha lokomisa ngekhenkcezisi ukuqinisekisa umgangatho wemveliso.ubukhulu bezinto ezibonakalayo: Ekubeni intlama yebhanana iqine kakhulu, ubukhulu obufanayo kufuneka bugcinwe ngexesha lokuveliswa ukuze kuthintelwe iingxaki ezifana nokudibanisa okanye ukoma okungaphelelanga. Okwesibini,ubushushu bokufudumeza ngexesha lokufakelwa kwe-sublimation: Uvavanyo lubonisa ukuba ixesha lokomisa liyancipha njengoko ubushushu beshelufu bunyuka ngaphakathi koluhlu olufanelekileyo (≤20°C). Nangona kunjalo, ukufudumala okugqithisileyo phantsi koxinzelelo oluphezulu lokusebenza kunokubangela ukunyibilika kwemveliso, nto leyo ebangela ukuba kubekho imida yobushushu. Okokugqibela,uxinzelelo lwe-sublimation: Uxinzelelo olusebenzayo luchaphazela kakhulu ubushushu kunye nokudluliselwa kobunzima. Izifundo zibonisa uxinzelelo olufanelekileyo (malunga ne-40Pa) olunciphisa ixesha lokomisa.
I-Fringe-drying curve isebenza njengophawu olubalulekileyo lwenkqubo yokomisa. Ngokuhlalutya ii-curves phantsi kweemeko ezahlukeneyo, iiparameter zenkqubo zinokulungiswa. Umzekelo, phantsi kweemeko ezifanelekileyo (ubukhulu be-8mm, ukufudumeza kwe-20°C, uxinzelelo lwe-40Pa), i-fringe-drying curve ibonisa i-sublimation ezinzileyo kunye ne-desorption, ixesha elifutshane lokomisa, kunye nomgangatho ophezulu wemveliso.
Ii-dryer dryers zibonisa iingenelo ezibalulekileyo kunye namathuba amaninzi okusetyenziswa kwimveliso ye-banana powder. Ngokulawula ngokungqongqo iiparameter eziphambili kunye nokwenza ngcono iinkqubo, umgangatho wemveliso kunye nokusebenza kakuhle kwemveliso kunokuphuculwa. Namhlanje, njengoko imigangatho yomgangatho wokutya iphakama, uluhlu olwahlukeneyo lwee-dryer dryers ze-BOTH—ezenzelwe iimfuno zomgangatho ophezulu—ziye zasetyenziswa kakhulu.Wamkelekile ukubuzaukuze ufumane iinkcukacha ezithe vetshe.
