Xa ubushushu bamanzi bufikelela kwindawo yokubilisa ye-chlorophyll, i-chlorophyll i-oxidized ngokulula, enokuphelisa i-oksijini kwizicubu zemifuno.Nangona iphathwa kwiqondo lokushisa eliphezulu, ithuba le-oxidation liyancitshiswa, ngoko liyakwazi ukugcina umbala walo oluhlaza.Ukongeza, imifuno ye-blanching inokunciphisa inani elikhulu le-asidi kwizicubu zemifuno eluhlaza.Xa uphathwa kumaqondo aphezulu, ukusebenzisana phakathi kweklorofili kunye ne-asidi kungancitshiswa, okwenza kube lula ukwenza i-pheophytin.
Ngokuqhelekileyo, indawo yokubilisa ye-chlorophyll iphantsi kakhulu kunendawo yokubilisa yamanzi, kwaye xa ifikelela kwindawo yokubilisa, i-chlorophyll iya kuba yi-oxidized.Emva kokuba i-oksijeni ikhutshwe, imifuno ayiyi kuba ne-oxidized kwaye inokugcina umbala wayo omtsha.Ngoko ke, ukuze ungafaki imifuno ye-blanch kwaye ufikelele kwindawo yokubilisa ye-chlorophyll, kuyimfuneko ukulawula ukushisa kwemifuno.
Ijenereyitha yomphunga isebenzisa ityhubhu yokufudumeza ukwenza ubushushu.Umbhobho wokufudumeza usetyenziselwa ukubonelela ngokuqhubekayo ubushushu kwibhoyili.Emva kokuba isixhobo sivuliwe, sinokuvelisa i-steam ephezulu yobushushu kwimifuno kwimizuzu emibini.Kufuneka kuphela ukudibanisa le generator umphunga kunye nezinye izixhobo.Ngokuyidibanisa, inokubonelela ngokuqhubekayo umphunga wobushushu obuphezulu kwimifuno.Oku kwahlukile kwiibhoyila eziqhelekileyo.Le jenereyitha yomphunga ayivelisi amaqondo obushushu aphezulu ekuhlaleni kwaye ibilisa kuphela ekuhlaleni.Endaweni yoko, inokuqinisekisa ukuba Yonke indawo ngaphakathi kwibhoyila inokufumana umphunga wobushushu obuphezulu ngokulinganayo.
Njengoko imifuno iyimveliso edliwayo, ukhuseleko olupheleleyo kufuneka luqinisekiswe ngexesha lokucubungula, ngakumbi impilo yamanzi kunye ne-steam.Ijeneretha ye-steam ixhotyiswe ngezixhobo zokucoca amanzi ukunyanga amanzi angena kwibhoyila ukuqinisekisa ukuba ubushushu obuphezulu obuvelisiweyo bucocekile.Akukho kungcola kwaye ihambelana ngokupheleleyo nemigangatho yococeko yokhuseleko lokulungisa ukutya.
Ngaphezu koko, ngelixa ilizwe likhuthaza ngamandla ukugcinwa kwamandla kunye nokukhuselwa kwendalo, ukusetyenziswa kweejenereyitha zomphunga kunokonga amandla ngelixa kunciphisa ukukhutshwa kwenitrogen oxide, eluncedo kakhulu kubavelisi, ilizwe kunye nabantu.
