Homemade Freeze Dryer

Cia kom qhuav, tseem hu ua lyophilization, yog txheej txheem uas tshem tawm cov dej los ntawm cov zaub mov lossis lwm yam khoom los ntawm kev khov nws thiab tom qab ntawd txo qis qhov chaw nyob ib puag ncig, tso cai rau cov dej khov rau sublime ncaj qha rau hauv vapor yam tsis tau mus txog theem ua kua. Txoj kev no khaws cov khoom noj khoom haus, xim, thiab kev ntxhib los mos zoo dua li cov txheej txheem ziab khaub ncaws, ua rau nws zoo tagnrho rau kev khaws zaub mov, kev tshawb fawb tshawb fawb, thiab kev siv tshuaj. Hauv tsab xov xwm no, peb yuav tshawb txog lub tswv yim ntawm lub tshuab ziab khaub ncaws hauv tsev, nws cov txiaj ntsig, cov khoom siv, kev tsim kho, thiab cov lus qhia siv.

 

Freeze-drying thev naus laus zis, lub npe puv tshuab ziab khaub ncaws, yog ib txoj kev khaws cia kom tshem tawm cov dej los ntawm cov khoom noj los ntawm cov txheej txheem ntawm qhov kub thiab txias thiab lub tshuab nqus tsev sublimation. Nws lub hauv paus ntsiab lus tuaj yeem muab faib ua peb theem: pre-freezing, sublimation thiab tsom xam.

​

Pre-freezing:Ua ntej tshaj plaws, cov khoom noj yog khov sai sai ntawm qhov kub thiab txias, kom cov dej hauv cov khoom noj muaj nyob rau hauv daim ntawv ntawm cov dej khov nab kuab, los tiv thaiv kev tsim cov dej khov loj hauv cov txheej txheem tom ntej los rhuav tshem cov qauv khoom noj.

 

Sublimation:Tom qab ntawd, hauv lub tshuab nqus tsev, cov dej khov nab kuab yog sublimed ncaj qha rau hauv dej vapor los ntawm cua sov, yam tsis mus dhau ntawm cov kua dej theem. Hauv cov txheej txheem no, qhov kub ntawm cov zaub mov tau khaws cia hauv qab qhov chaw khov, kom tsis txhob poob ntawm cov as-ham thiab kev loj hlob ntawm cov kab mob.

 

Thaum kawg, txuas ntxiv kom sov thiab decompress, thiab tshem tawm tag nrho cov dej seem hauv cov zaub mov hauv daim ntawv gaseous kom ua tiav lub hom phiaj ntawm kev khaws cia mus ntev.

Freeze drying muaj ntau qhov zoo dua li lwm txoj kev ziab khaub ncaws:

Khoom noj khoom haus Retention:Kev ziab qhuav khaws cia feem ntau ntawm cov as-ham, vitamins, thiab enzymes pom hauv cov zaub mov tshiab.

Lub neej txee:Cov khoom khov-qhuav muaj lub neej txee ntev dua li lawv cov khoom tshiab, ua rau lawv zoo tagnrho rau kev npaj thaum muaj xwm txheej ceev thiab khaws cia ntev.

Lub teeb thiab compact:Cov khoom noj khov-qhuav siv qhov chaw tsawg dua thiab hnyav dua li cov khoom noj hauv kaus poom los yog lub cev qhuav dej, ua rau lawv yooj yim rau kev mus ncig thiab mus pw hav zoov.

Rehydration:Cov khoom noj khov-qhuav rehydrate sai thiab khaws lawv cov kev ntxhib los mos thiab tsw thaum ntxiv dej.

 

Thaum koj lub tshuab ziab khaub ncaws hauv tsev ua haujlwm, ntawm no yog qee cov lus qhia siv nws:

● Npaj Cov Khoom Noj:Xaiv cov zaub mov uas tsim nyog rau khov kom qhuav, xws li txiv hmab txiv ntoo, zaub, thiab nqaij. Txiav los yog tsuav cov zaub mov rau hauv me me kom nce qhov chaw thiab ua kom cov txheej txheem sublimation.

● Froze cov zaub mov:Muab cov zaub mov tso rau hauv lub tshuab nqus tsev chamber thiab khov rau qhov xav tau kub. Qhov no feem ntau yog ua ntej-txias lub chamber thiab cia cov zaub mov kom khov rau ob peb teev.

● Pib lub Freeze-Drying Process:Thaum cov zaub mov khov lawm, pib txheej txheem khov-drying los ntawm kev txo qis hauv lub chamber thiab ua kom cov cua sov ua kom sov. Saib xyuas qhov kub thiab txias kom ze kom ntseeg tau tias lawv nyob hauv qhov xav tau.

● Saib xyuas kev nce qib:Saib xyuas kev ua tiav ntawm cov txheej txheem khov-qhuav los ntawm kev soj ntsuam cov khoom noj thiab tshuaj xyuas cov kev nyeem ntawv siab thiab ntsuas kub. Kho cov kev teeb tsa raws li xav tau los ua kom zoo dua.

● Khaws Cov Khoom Noj Dawb-Dried:Thaum cov txheej txheem khov-drying tiav lawm, tshem tawm cov zaub mov los ntawm lub tshuab nqus tsev thiab khaws cia rau hauv cov thawv ntim cua. Sau lub thawv nrog lub npe ntawm cov zaub mov thiab hnub uas nws khov-qhuav.

 

Nyob rau hauv lub ntsej muag ntawm ib tug ntau yam ntawm tsev neeg freeze-drying tshuab khoom nyob rau hauv lub lag luam, cov neeg siv feem ntau xav tias tsis muaj peev xwm pib. Nov yog qee yam tseem ceeb uas yuav tsum tau saib xyuas thaum yuav khoom:

 

Freezing peev:Lub peev xwm khov yog ib qho tseem ceeb ntsuas ntsuas kev ua haujlwm ntawm lub tshuab ziab khaub ncaws, uas yog ncaj qha ntsig txog qhov ceev thiab cov nyhuv ntawm cov zaub mov ua ntej khov. Feem ntau, lub zog ntau dua thiab ntau dua lub tshuab tub yees, qhov muaj zog dua nws lub peev xwm khov.

Vacuum degree:Lub tshuab nqus tsev kawm ntawv ncaj qha cuam tshuam rau kev ua haujlwm thiab cov nyhuv ntawm cov txheej txheem sublimation. Cov tshuab ziab khaub ncaws kom qhuav zoo yuav tsum muaj lub tshuab nqus tsev zoo thiab cov tshuab sealing kom paub meej tias lub tshuab nqus tsev txaus ua tiav thaum lub sijhawm sublimation txheej txheem.

Peev xwm loj:Xaiv lub peev xwm tsim nyog raws li qhov xav tau tiag tiag ntawm tsev neeg. Rau cov tsev neeg me, me me los yog lub tshuab ziab khaub ncaws me me yuav tsim nyog dua; Rau cov tsev neeg uas yuav tsum tau ua cov khoom xyaw zaub mov ntau, cov khoom muaj peev xwm loj yuav tsum tau xaiv.

Kev ua haujlwm yooj yim:Kev yooj yim ntawm kev siv thiab kev txawj ntse kuj yog qhov tseem ceeb uas yuav tsum tau xav txog thaum yuav khoom. Qee lub tshuab ziab khaub ncaws high-end tau nruab nrog cov yam ntxwv siab heev xws li kov lub vijtsam thiab kev tswj hwm ntse, uas tuaj yeem txhim kho cov neeg siv kev paub zoo.

Hom thiab tom qab muag:Xaiv cov npe nrov thiab cov lag luam nrog cov kev pab cuam tom qab muag zoo los yuav, kom ntseeg tau cov khoom zoo thiab kev saib xyuas tom qab.

 

Npaj cov khoom xyaw:Ntxuav, hlais lossis tsuav cov khoom xyaw uas yuav tsum tau khov-qhuav thiab ua ntej kho raws li xav tau (xws li pickling, ua noj, thiab lwm yam).

Pre-freezing kev kho mob:Muab cov zaub mov ua tiav rau hauv lub tub yees ntawm tsev neeg lub tshuab ziab khaub ncaws rau kev kho mob ua ntej kom khov kom txog thaum cov zaub mov khov tag.

Kev teeb tsa parameter:Tsim nyog ntsuas qhov ntsuas kub, nqus tsev kawm ntawv thiab lub sijhawm ntawm lub tshuab ziab khaub ncaws raws li hom thiab tuab ntawm cov khoom xyaw.

Pib freeze-drying:Muab cov khoom xyaw ua ntej khov rau hauv qhov chaw khov-qhuav, kaw lub qhov rooj thiab pib txheej txheem khov-qhuav. Nyob rau hauv lub freeze-drying txheej txheem, nws yog ib qho tsim nyog yuav tsum tsis tu ncua xyuas qhov kev khiav hauj lwm ntawm lub freeze-drying tshuab thiab lub freeze-drying qhov teeb meem ntawm cov zaub mov.

Sau cov khoom tiav:Tom qab cov txheej txheem khov-qhuav dhau lawm, qhib lub qhov rooj ntawm chav tsev khov-qhuav, tshem tawm cov khoom noj khov-qhuav thiab khaws cia.
