Cov txiv nkhaus taw qhuav qhuav, muaj npe nrov rau nws cov kev ntxhib los mos thiab cov txiaj ntsig zoo rau kev noj qab haus huv, tau dhau los ua cov khoom noj txom ncauj nrov heev, tshwj xeeb tshaj yog nyiam los ntawm cov neeg siv khoom tsom rau kev tswj qhov hnyav thiab kev noj qab haus huv. Tsis zoo li cov txiv nkhaus taw qhuav, khov-qhuav txiv nkhaus taw yog tsim los ntawm dehydrating txiv hmab txiv ntoo nyob rau hauv ib qho chaw qis-kub siv cov khoom noj khoom haus khov tshuab ziab khaub ncaws. Nws tsis muaj additives, yog tsis-kib, khaws cia lub ntuj tsw thiab khoom noj khoom haus Cheebtsam ntawm txiv nkhaus taw, ua rau nws yog ib qho zoo tagnrho-calorie lub teeb zaub mov xaiv.
Yog li, yuav ua li cas raws nraim cov txiv hmab txiv ntoo qhuav qhuav? Siv covPFD-200 freeze dryer's mango freeze-drying trial as a case study, this article will detail the tiav technological process and key technical parameters for freeze-drying fruits and zaub, deciphering the science behind freeze-dried food.
Txias-Dried Mango Process Flow thiab Key Technical Parameters
Hauv qhov kev sim no, peb tau sim ntsuas qhov khov-qhuav ntawm mangoes siv PFD-200 pilot-scale freeze dryer, txiav txim siab qhov kev ua haujlwm zoo tshaj plaws. Cov txheej txheem tshwj xeeb yog raws li hauv qab no:
1. Qib Pretreatment
Txiv Hmab Txiv Ntoo Xaiv: Ua tib zoo xaiv cov txiv nkhaus taw tshiab, siav kom ntseeg tau tias cov khoom siv raw zoo.
Peeling thiab Pitting: Tshem tawm cov tev thiab lub qhov dej, khaws cov pulp ntshiab.
Slicing: Slice lub pulp tusyees kom ntseeg tau tias kev ziab kom zoo ib yam.
Ntxuav thiab tua kab mob: Ua kom huv si thiab tua cov txiv nkhaus taw kom ua raws li cov qauv kev nyab xeeb ntawm zaub mov.
Thawv Thauj Khoom: Muab cov txiv nkhaus taw uas npaj txhij rau ntawm cov tais khov-qhuav, npaj rau theem khov-qhuav.
2. Lub Sij Hawm Ua Kom Qhuav
Pre-freezing: Ceev nrooj khov cov txiv nkhaus taw ntawm ib puag ncig ntawm -35°C rau -40°C rau kwv yees li 3 teev, kom ntseeg tau tias kev ncaj ncees ntawm cov qauv ntawm cov txiv hmab txiv ntoo.
Kev ziab thawj zaug (Sublimation Drying): Tshem tawm feem ntau ntawm cov dej noo ntawm sublimation nyob rau hauv lub ziab chamber siab ntawm 20 ~ 50 Pa.
Secondary Drying (Desorption Drying): Ntxiv rau qhov txo kom qhuav chamber siab rau 10 ~ 30 Pa, tswj cov khoom kub ntawm 50°C thiab 60°C kom huv si tshem cov dej khi.
Lub sijhawm ziab tag nrho yog kwv yees li 16 mus rau 20 teev, kom ntseeg tau tias cov dej noo ntawm cov txiv nkhaus taw ua tau raws li cov qauv thaum khaws cia lawv cov xim, tsw, thiab khoom noj khoom haus.
3. Tom qab ua tiav theem
Sorting: Ua zoo sorting ntawm khov-qhuav mango slices, tshem tawm cov khoom uas tsis yog-conforming.
Weighing: Precisely luj lub slices raws li specifications.
Ntim: Siv cov ntim ntim hermetic nyob rau hauv ib puag ncig tsis muaj menyuam kom tiv thaiv kom tsis txhob ya raws thiab kev kis kab mob, yog li txuas ntxiv lub neej txee.
Khoom nta Highlight:
Freeze-Drying Chamber: Tsim los ntawm 304 zaub mov-qib stainless hlau, featuring sab hauv daim iav polishing thiab sab nrauv sandblasting kev kho mob, combining zoo nkauj nrog tu cev.
Energy Efficiency thiab Stability: Cov cuab yeej ua haujlwm ruaj khov nrog kev siv hluav taws xob tsawg. Nws yog qhov tsim nyog rau kev tsim cov khoom noj khov-qhuav, suav nrog txiv hmab txiv ntoo, zaub, nqaij nruab deg, nqaij, dej haus tam sim, thiab cov zaub mov tsiaj, ua rau nws yog qhov kev xaiv zoo tshaj plaws rau kev tsim khoom me me rau nruab nrab thiab kev tshawb fawb.
Los ntawm qhov kev sim PFD-200 freeze dryer ntawm mangoes, peb tsis tau tsuas yog tshawb xyuas cov txheej txheem zoo tshaj plaws rau cov txiv nkhaus taw khov xwb tab sis kuj qhia tau tias yuav ua li cas khov-drying thev naus laus zis kev tshawb fawb khaws cia cov yam ntxwv ntawm cov zaub mov, ntsib cov neeg siv khoom niaj hnub xav tau kev noj qab haus huv, noj qab haus huv, thiab khoom noj txom ncauj yooj yim. Nyob rau hauv lub neej yav tom ntej, peb yuav txuas ntxiv optimize freeze-drying txheej txheem thiab txhawb lub tshiab daim ntawv thov ntawm freeze-drying technology nyob rau hauv cov zaub mov kev lag luam.
