How does ultrasonic technology revolutionize modern extraction processes?
Okuqukethwe
    Njengendlela esebenza kahle yokwelashwa ngokomzimba futhi oluhlaza, ubuchwepheshe be-homogenization ye-ultrasonic bukhombisile izinzuzo ezibalulekile emkhakheni wokukhishwa eminyakeni yamuva. Lo mbhalo wethula ngokuhlelekile ngokuhleleka komgomo wokusebenza we-homogenization we-ultrasonic, uhlaziya ngokuningiliziwe uhlelo lwalo oluthile ekukhishweni kwezithako ezisebenzayo zezitshalo, izakhi zomzimba kanye nezithako zokwelapha, zidingida kakhulu kulobu buchwepheshe obuqhathaniswa nezindlela zalo zentuthuko.

    2. Ukusebenza komgomo wobuchwepheshe be-homogenization ye-ultrasonic

    2.1 I-Cavital Effect Mechanism
    Umsebenzi oyisisekelo we-homogenization ye-ultrasonic uvela emphumeleni we-cavitation - Lapho ephezulu - amandla amagagasi e-ultrasonic (imvamisa 20KHZ - 1MHz) asakaza ku-liquid medium, ukushintshana kwamagagasi okucindezela amabi nawodwa akhiqizwa. Engcebweni engemihle uhhafu - umjikelezo, uketshezi luhambisana nengcindezi eshubile ukwakha ama-microbubble; Esikhathini esilandelayo sengcindezi enhle uhhafu - umjikelezo, la ma-bubble awela ngokushesha, ukukhiqiza amazinga okushisa aphezulu wendawo afinyelela ku-5000k kanye nezingcindezi eziphakeme ze-50MPA. Lesi simo esedlulele singabhubhisa ngempumelelo isakhiwo sodonga lweseli futhi sikhuphule i-solvent permeability.

    2.2 imiphumela yamabili imiphumela synergistic
    Ngaphezu kwe-Cavitation Eccount, i-ultrasound ibuye ikhiqize imiphumela ehlukahlukene ye-synergistic Effects:

    Umthelela we-Microjet: Ukuqhamuka kwe-asymmetric bubble kukhiqize ama-microjets ngejubane elidlula i-100m / s
    Umphumela we-Shear Force Effect: Okuphezulu - Ukudlidliza imvamisa
    Umphumela we-thermal: Ukuguqulwa kwamandla kubangela ukwanda okulinganiselayo kokushisa kohlelo (okuvame ukulawulwa ngo-50 - 60 ℃)
    Umphumela wamahhala we-radical

    3. Izindawo ezikhulu zohlelo lokusebenza

    3.1 Ukukhishwa kwezithako ezisebenzayo zezitshalo
    Ekukhishweni kwama-flavonoids, usizo lwe-ultrasonic lungakhuphula izinga lokukhishwa ngo-30 - 50%, futhi linciphise isikhathi sokucubungula kusuka emahoreni ambalwa kuya kwemizuzu engu-15 - imizuzu engama-30. Isibonelo, ekukhishweni kwamaqabunga e-ginkgo, uma kuqhathaniswa nendlela yendabuko ye-ethanol Reflux, ukwelashwa kwe-ultrasonic (40Khz, 300w) ukukhulisa isivuno se-quercetin kusuka ku-2.1% kuya ku-3.4%.
    Ukukhishwa kwama-polyphenols nakho kusizakale kakhulu. Isivuno se-hydroxytyrosol samaqabunga omnqumo ngemuva kokukhishwa kwe-ultrasonic (25KHZ, ama-80% amplitude) imizuzu engama-20 ephakeme kunaleso sokukhishwa okungamahora angama-24, futhi umsebenzi we-antioxidant wawungaqondile.

    Isicelo se-3.2 embonini yokudla
    Emkhakheni wokukhishwa kwamafutha, ukwenziwa kwe-ultrasonic kungakhuphula izinga lokukhishwa kwamafutha e-soybean ngo-12 - 18%, ngenkathi kunciphisa inani le-solvent cishe ngama-30%. Kuyaphawuleka kakhulu ukuthi ukudonswa kwe-miccaving okukhiqizwe yi-ultrasound kungabhubhisa ngempumelelo ukwakheka kwe-membrane kwamaseli omzimba wamafutha, kepha ngeke kubangele ukwehla kwamafutha acid.
    Ngokuya nge-protein extraction, ukwelashwa kwe-ultrasonic (20KHZ, isikhawu sokuphumula 1: 1) kungakhuphula isilinganiso sokukhishwa kwamaprotheni we-soya kusuka ku-68% kuya ku-85%, futhi i-protein dispitor Index (PDI) ingandiswa ngamaphesenti ayi-15.

    3.3 Ukukhishwa kwezithako zokwelapha
    Ukukhishwa kwe-alkaloids enjenge-vinblastine, i-ultrasound - Ukukhishwa okusizayo kwenza isikhathi sokukhishwa kusuka emahoreni ayi-8 kuya ku-45. Izifundo kumapharamitha wenqubo ebalulekile zibonisa ukuthi i-ultrasound (40KHZ) inomphumela omuhle kakhulu ngaphansi kwezimo ezingama-70% ethanol okuhlushwa, 1:15 Izinto zokushisa uketshezi, nokushisa okungama-50 ° C.
    Ekukhishweni kwe-terpenoid compounds, izinga lokushisa eliphakeme lendawo kanye nengcindezi ephezulu ekhiqizwe yi-ultrasound ilungele ikakhulukazi ukugcinwa kwezingxenye eziguqukayo. Ukukhishwa kwe-Ultrasonic kwamafutha we-peppermint akufinyeleli kuphela isikhathi ngo-80%, kepha futhi kukhulisa okuqukethwe kwe-mepoli ngo-8 - 12% uma kuqhathaniswa nokufakwa komoya.
