Lub tshuab nqus tsev khov yog tsim rau ziab cov khoom siv qib siab, lom, zaub, zaub mov, txiv hmab txiv ntoo, tshuaj, tshuaj intermediates thiab lwm yam ntaub ntawv. Lub tshuab nqus tsev khov kom qhuav yog ib hom tshiab ntawm lub thawv qauv uas ua ke nrog lub tub yees, lub tshuab nqus tsev, lub tshuab hluav taws xob hloov hluav taws xob, thiab tshem tawm cov dej noo ntawm lub tshuab nqus tsev vacuum. Nws siv qhov chaw khaws cov ntaub ntawv hauv lub thawv kom qhuav.
Cov txheej txheem tsim khoom ntawm lub tshuab nqus tsev khov-qhuav yog muab faib ua cov khoom xaiv, ntxuav, txiav, blanching, kom tsis muaj menyuam thiab lwm yam txheej txheem. Nws yuav tsum tau tshem tawm cov kab, qe, thiab cov khib nyiab uas txuas nrog cov hauv paus hniav, stems thiab nplooj, tshem tawm cov khib nyiab hlau nrog cov hlau nplaum, tshem tawm cov khoom txawv teb chaws xws li cov plaub hau thiab nplai nrog hluav taws xob zoo li qub, thiab tsis txhob muaj cua sov. Tsuas yog nrog kev kho mob ua ntej zoo tuaj yeem tsim cov khoom noj khov-qhuav zoo.
Ceev-khov cov ntaub ntawv uas tau kho ua ntej, qhov khov sai dua, qhov me me ntawm cov muaju hauv cov ntaub ntawv, thiab qhov kev puas tsuaj tsawg dua rau cov qauv thiab lub koom haum ntawm cov ntaub ntawv. Lub sijhawm khov yog luv luv, thiab cov protein yuav tsis hloov pauv zoo raws li kev ua ntawm coagulation thiab concentration.
Cov zaub mov khov sai yuav tsum tau nqus-sublimated thiab qhuav sai, thiab lub tshuab nqus tsev kawm ntawv yuav tsum ncav cuag lub sublimation siab sai, thiab sublimation tshav kub lub zog yog muab nyob rau hauv lub sij hawm los tswj lub sublimation kub. Radiation cua sov feem ntau yog siv.
Cov khoom noj khov-qhuav yog ntxeem tau, thiab cov ntaub so ntswg yog 100 mus rau 150 lub sij hawm loj dua li qub, yog li lub caij nyoog ntawm kev sib cuag nrog oxygen nce. Thaum rov qab mus rau qhov qub siab los ntawm qhov kub thiab txias, nws yuav tsum tau nqa tawm hauv ib puag ncig nitrogen. Kev sib tsoo thiab ntim khoom yuav tsum tau nqa tawm ntawm cov av noo ntawm 30-40 feem pua thiab qhov kub hauv qab 25 degree . Txhawm rau kom cov dej noo ntawm cov zaub mov qhuav qis dua 5 feem pua, yuav tsum tau muab cov desiccant tso rau hauv lub pob kom nqus tau me me ntawm cov dej noo. Cov khoom ntim yuav tsum tau xaiv nrog cov huab cua tsis zoo permeability, siab zog thiab xim sib sib zog nqus.
Lub tshuab ziab khaub ncaws tuaj yeem ua ntau yam zaub, txiv hmab txiv ntoo, ntses, instant noodles, condiments, kas fes, tshuaj yej, thiab lwm yam.
