Puas yog instant tshuaj yej freeze-dried?

Lub tshuab nqus tsev khov-drying txheej txheem suav nrog pre-freezing cov khoom thiab tom qab ntawd tshem tawm cov dej noo los ntawm sublimating dej khov ncaj qha rau hauv vapor hauv lub tshuab nqus tsev. Ua ntawm qhov kub thiab txias, txoj kev no tsis txhob thermal degradation ntawm cov khoom kub-rhiab, ua kom muaj kev ruaj ntseg ntawm cov khoom siv roj ntsha thiab cov khoom siv physicochemical. Piv nrog rau cov tshuaj tsuag kom qhuav, lub tshuab nqus tsev khov-drying ua cov khoom nyob ze rau lawv lub xeev ntuj, nrog cov dej solubility zoo dua thiab cov khoom ua kom rov ua dua tshiab.

Qhov zoo ntawm Nqus Freeze-Drying hauv Instant Tea Production (Summarized los ntawm "OB"):

1.Preservation ntawm tshuaj yej tsw: Cov txheej txheem kub tsis tshua muaj txiaj ntsig zoo tiv thaiv kev poob ntawm cov tshuaj tsw qab uas tsis muaj ntxhiab, ua kom cov tshuaj yej instant hmoov khaws nws cov tshuaj tsw qab nplua nuj.

2.Kev tiv thaiv cov khoom noj: Tshuaj yej muaj ntau cov tshuaj polyphenolic, amino acids, thiab cov kab mob muaj txiaj ntsig. Kev ziab kom qhuav ua tiav lub cev qhuav dej zoo yam tsis muaj kev puas tsuaj rau cov khoom rhiab, khaws cia cov tshuaj yej cov khoom noj muaj txiaj ntsig.

3. Txhim khu kev xav zoo: Txias-dried tshuaj yej hmoov pov thawj zoo, cov khoom sib xws, xim ntuj, thiab tsis txhob browning ntau nyob rau hauv cov pa kom qhuav. Nws cov qauv ntxeem tau tso cai rau kev tawg sai sai yam tsis muaj qhov seem, txhim kho cov neeg siv khoom.

4.Extended Txee Lub neej: Dej khov-dried instant tshuaj yej muaj tsawg kawg nkaus noo noo, tiv taus noo noo nqus thiab pwm loj hlob, thiab tswj kom zoo thaum lub sij hawm ntev cia ntawm chav tsev kub.

 Optimization of Freeze-Drying Parameters for Instant Tea:

Txhawm rau ua kom tau txais txiaj ntsig zoo instant tshuaj yej hmoov, cov txheej txheem tseem ceeb yuav tsum tau tsim thiab ua kom zoo dua:

Extraction tej yam kev mob: Kub (piv txwv li, 100 ° C), ncua sij hawm (piv txwv li, 30 feeb), thiab rho tawm cycles cuam tshuam cov tshuaj yej cawv zoo. Cov kev tshawb fawb pom tau hais tias optimized extraction boosts cov yield ntawm cov khoom xyaw nquag xws li tshuaj yej polyphenols.

Pre-Freezing Kub: Feem ntau teem ib ncig ntawm -40 ° C kom ua tiav cov dej khov siv lead ua, tso lub hauv paus rau kev ua kom zoo sublimation.

Drying Rate Control: Maj mam cua sov khaws cov khoom lag luam ruaj khov. Kev kub ceev los yog qeeb qeeb tuaj yeem cuam tshuam qhov zoo.

Txias Trap Temperature & Vacuum Level: Lub tshuab cua txias hauv qab -75 ° C thiab lub tshuab nqus tsev ≤5 Pa txhim kho dehumidification efficiency thiab txo lub sij hawm kom qhuav.

"OB" Perspective:
Lub tshuab nqus tsev khov-drying tsis tsuas yog txhawb nqa cov tshuaj yej zoo nkaus xwb tab sis kuj nthuav dav nws cov ntawv thov - xws li muab nws tso rau hauv cov khoom noj khoom haus rau cov khoom noj txom ncauj, dej haus, thiab cov khoom siv tawv nqaij. Cov thev naus laus zis no tseem txhawb nqa SMEs kom nkag mus rau lub lag luam tshuaj yej tam sim, tsav kev txhim kho kev lag luam thiab kev tsim kho thev naus laus zis.
