Yuav ua li cas ua cov naj hoom los ntawm cov kuab tshuaj extraction
1. Tub ntxhais tseem ceeb
Dissolve cov duab uas muaj ntxhiab tsw qab rau cov nroj tsuag uas siv cov emvents organic (piv txwv li, hexane, ethanol) kom tsis txhob muaj tus ntxhiab tsw qab nrog kub.
Muaj feem r raw cov ntaub ntawv: jasmine, Rose, Ntshiab, thiab lwm yam cua sov-}} rawv cov ntaub ntawv.
2. Cov ntaub ntawv thiab cov cuab yeej
Cov khoom siv raw: tshiab paj tej nplaim (500g) lossis cob (100g).
Cov kuab tshuaj: Khoom noj {{{{{{}} qib hexane (thawj extraction), 95% ethanol (thib ob extraction).
Cuab Yeej: Iav {{- daim ntawv ntim, cov khoom siv cov khoom siv distillation (los yog dej da dej kub), cov xim av daj.
Kev ceev faj kev nyab xeeb: hnab looj tes, kev ua pa.
3. Kev ua haujlwm cov txheej txheem
① Thawj cov tshuaj tsw qab (ua kom muaj cov ntxhiab tsw qab)
Soak cov petals lossis cob nyob rau hauv hexane (piv 1: 3), foob, thiab khaws cia ntawm lub teeb rau 2 hnub.
Tom qab pom thiab distillation (kom rov qab hexane), cov khoom siv viscous yog lub siab xav.
El Ob-Extraction Alpary (los tsim cov thawj essence)
Yaj lub siab hauv ethanol (piv 1: 5) thiab cia nws zaum rau 7 hnub.
Tom qab pom, tus thawj essence tau txais. Hnub nyoog nws rau 1 lub hlis nyob deb ntawm lub teeb.
Blacking Black Perfume
Daim ntawv qhia: thawj essence (10%) + dej cawv (85%) + dej (5%).
Tom qab sib tov, ntim thiab hnub nyoog rau 2 lub lis piam, tom qab lim thiab lub raj mis.
4. Cov ntawv tseem ceeb
Kev Nyab Xeeb: Hexane yog flammable - Ua haujlwm hauv ib qho zoo-} ventilated cheeb tsam.
Qhov kub: kom distillation kub tsawg dua los yog sib npaug rau 50℃kom tsis txhob ua kom muaj kev puas ntsoog.
Kev lim: tshem tawm siv tsis tau yooj yim kom tiv thaiv kom tau huab.
5. Qhov yooj yim hauv tsev
Cov nplaim hluavtaws ncaj qha hauv 95% ethanol rau 7 hnub, lim thiab mloog zoo, tom qab ntawd muab cov naj hoom (hla cov kauj ruam ntawm hexane).
6. Cov lus nug nquag nug
Pungent tsw? Txuas ntxiv rau lub sijhawm laus.
Cov tshuaj tsw qab luv rov qab mus? Ntxiv 1-2% glycerin lossis pepleuli roj raws li kev txhim kho.
Kev khaws cia: Cov khw ntim khoom hauv qhov chaw txias, tsaus.
Tsuas yog 4 kauj ruam (steeping → lim → distilling → blending), thiab koj tuaj yeem tsim koj tus kheej cov tshuaj tsw qab!
