Freeze-dried khoom - ib tug tseem ceeb khoom plig ntawm science los rau noob neej

Lub yees whirlwind tawg mus rau hauv peb lub neej txhua hnub, nyob rau hauv peb lub neej txhua hnub. Tshiab khoom tu cev cov khoom thiab tej khoom hauv tsev, unprecedented kitchenware, neeg electronics, high-tech fabrics ntse coexist nyob rau hauv niaj hnub tsev. Innovation tawg mus rau peb cov lus, peb daim hlau thiab tsom-iav. Nyob rau hauv tsis ntev los no xyoo lawm, vim kev txaus siab ntawm cov neeg mus rau kev kawm ntawm kev noj qab nyob noj tau ua nce nrov freeze-dried cov khoom.

Lub cev hauv paus ntsiab lus ntawm sublimation

Sublimation los yog sublimation, - ib tug transformation los ntawm khoom tshuaj ncaj qha mus rau hauv lub gaseous lub xeev, tsis suav cov kua theem.

Khov qhuav los lyophilisation, - ib tug ua kua extraction txheej txheem los ntawm lub frozen lom khoom. Nws yog raws li nyob rau hauv lub evaporation ntawm cov dej khov muaj nyob rau hauv lub khov khoom, i.e. nws txoj kev hloov mus ncaj qha mus rau hauv lub vapor lub xeev, tsis suav cov kua theem.

sublimation txoj kev twb tsim nyob rau hauv thaum ntxov XX xyoo pua, ib tug txawj ntse Lavxias teb sab inventor Lappa Starzhenetsky-GI, nyob rau hauv 1921 patented ib txoj kev sublimation nyob rau hauv txo siab. Rau cov thawj lub sij hawm nyob rau hauv lub ntiaj teb no ntawm sublimation kom qhuav siv nyob rau hauv lub forties nyob rau hauv lub USSR rau lub preservation ntawm sera, ntshav ntshav thiab penicillin.

Secrets ntawm muaj ntau lawm

Freeze-dried cov khoom ua los ntawm lub tshuab nqus tsev sublimation.

Ua ntej ua tus thawj tej yam ntuj tso khoom undergoes sai khov ntawm ib tug kub mus txog -200 ° C. Nws zoo dua, tsis zoo li cov pa khov uas tshwm sim nyob rau hauv cov nqaij tsim ntawm cov dej khov muaju yog li me me hais tias lawv yuav tsis txawm ua txhaum lub cell week.

Ces tus frozen khoom yog muab tso rau hauv ib lub kaw chamber los ntawm uas pib los mus twj cua. Tom qab txo lub siab nyob rau hauv lub chamber pib maj mam nce qhov kub thiab txias. Mis nyuj suab, cov generated vapor yog pumped. Thaum uas tag nrho cov dej khov muaju ntawm cov khoom yuav qhuav, tsim txoj kev ua tiav.

Ntxiv mus, lub siab equalization chamber nkag inert roj, nitrogen los yog Helium. Lub chamber yog qhib, lub qhuav cov khoom uas txawb, yog dai, ntim nyob rau hauv gazoparonepronitsaemye tej pob khoom. Los ntawm lub ntim yog pumped huab cua, nitrogen pumped nyob rau hauv lieu thereof, thiab cov pob yog ntim.

Khov-qhuav zaub mov: cov kev pab cuam thiab harms

Khov kom qhuav muab kev nyab xeeb, tsis muaj kev zam, tag nrho cov pab zog thiab organoleptic yam ntxwv ntawm cov khoom. Qhov no txoj kev preserves lub zoo heev txiv hmab txiv ntoo thiab berries, zaub thiab nceb, tshuaj ntsuab, khoom noj siv mis, confectionery, cov nqaij thiab cov ntses, kua zaub thiab porridges.

Daim ntawv thov kev qhia tau hais tias sublimates txawm superior nyob rau hauv saj thiab noj haus thaj chaw ntawm lub natural counterparts. Nws yog ib qho nyuaj rau xav txog tej yam uas ib tug neeg yuav zoo siab rau haus tej yam ntuj tso beet thiab zaub qhwv kua txiv thiab kav kua txiv thiab zaub txhwb qaib, thiab dej qab zib nyob rau hauv ua noj ua haus uas siv ib tug zoo xws li cov freeze-dried cov khoom muaj lub zoo heev xyuas. Qhuas kuj khov-qhuav berries thiab txiv hmab txiv ntoo, thiab khoom noj siv mis.

Sublimates tsis muaj ib yam preservatives los yog dyes, thiab nyob rau hauv uas lawv lub ntsiab kom zoo dua piv nrog rau lwm cov khoom ntawm ntev-lub sij hawm cia thiab ceev ceev kev npaj.

Lub tsuas txaus ntshai hais tias yuav nrog tus purchase ntawm sublimates - tus thawj tsawg-zoo raw cov ntaub ntawv siv los ntawm unscrupulous manufacturers. Koj muaj peev xwm tiv thaiv koj tus kheej los ntawm kev yuav khoom khoom ntawm cov pov thawj tuam txhab uas muag.

Sublimation - cov tshuaj rau ntau cov teeb meem

Freeze-dried cov khoom yuav tau lug siv ob qho tib si raws li ib tug instant zaub mov, thiab raws li muaj semi-tiav lawm confectionery, khoom noj khoom haus concentrates, mis nyuj thiab nqaij, naj hoom thiab lwm yam lag luam.

Nyob rau hauv zus tau tej cov mis nyuj cov khoom, qhuav soluble tshuaj tua kab mob, kab mob thiab kab mob preparations, kev pab noj haus, enzymes, ferments thiab lub tshuab nqus tsev sublimation twb tsis muaj lwm txoj kev.

Freeze-dried khoom - qhov zoo tshaj plaws kev xaiv los xyuas kom meej cov zaub mov nyob ntev hikes thiab mus ncig ua si. Cov kev lawv siv raws li tej yam yooj yim li sai tau: dej yog ntxiv rau cov khoom, thiab nws yog npaj txhij. Nws yuav tsum tau tsuas nco ntsoov tias qhov rov qab npaum li cas sublimate nyob rau hauv dej kub, nws yog poured.

Tsev neeg ntau lawm

Tus txheej txheem ntawm lub tshuab nqus tsev sublimation technologically complex, yuav tsum tau tshwj xeeb kev txawj ntse thiab kev cob qhia, kev siv cov kev muaj khoom.

Yog li ntawd amateur tswv yim pom zoo nyob rau hauv qhov Web site ntawm yuav ua li cas los npaj freeze-dried cov khoom nyob rau hauv lub tsev yuav ua tau ib tug zoo kev pab rau tourists thiab yos hav zoov uas xav kom tsis txhob tus luj ntawm hnab nqa taug kev vim qhuav uas npaj tais diav, tab sis rau ib tug lub tshuab nqus tsev sublimation ntawm frozen khoom noj, lawv yuav tsis muaj feem.

Lwm yam - lub qhuav ntawm cov khoom nyob rau hauv lub txias, raws li nws tau ua rau cov centuries cov neeg ntawm sab qaum teb lub teb chaws. Weathered tus mob khaub thuas slices ntawm nqaij thiab cov ntses tsis deteriorate, ua sib zog thaum tswj nws loj, zoo lawm thiab organoleptic zog.

Sublimates yog dav faib ib ncig ntawm lub ntiaj teb no, nyob rau hauv Russia lawv tsuas yog nkag mus rau hauv tej chaw. Tab sis, nrog txhua dua hnub ntau thiab ntau pom tseeb hais tias lawv yog ib tug zoo kawg nkaus kev xaiv ntawm kev noj qab nyob cov khoom noj. Khov-qhuav khoom - nqi lub foundations, ib tug khoom plig ntawm science rau noob neej.
