Kev ua npuas ncauj luam ntawv txheej txheem
Ua npuas ncauj luam ntawv tseem muaj cov foaming puag ua ntej thiab tom qab ntawv npog; thawj hauv qab daus, tom qab ntawd ua npuas ncauj npog nto.
Ua npuas ncauj ua ntej, tom qab ntawd npog cov txheej txheem saum npoo:
Tes ntawv: npaj cov khoom xyaw, npaj, tsheb ciav hlau, npaj cov ntawv luam tawm ua ntej kev tsim khoom) → daim ntaub npog → ua npuas dej primer (3 ~ 4 zaug) → tshuab (kub (yuav tsum zoo ib yam, tsis muaj txau) → npog (2 ~ 3 zaug)) → ziab → ntsuas kub dhau (120-130 ℃) xovxwm (lub zog 160 ~ 180W, 6-8S) → kev kuaj xyuas → kev xa khoom.
Tshuab luam ntawv: kev npaj ua ntej kev tsim tawm (sib xyaw, kev npaj, kev cob qhia, kev npaj cov ntawv luam tawm) → nthuav tawm → ua npuas ncauj thiab pib siv (3 ~ 4 zaug, ziab rau tib lub sijhawm) → npog (2 txog 3 zaug, kom qhuav tib lub sijhawm) → Kho kom zoo dua (120 ~ 130 ℃) → xovxwm tshuab (lub zog 160 ~ 180W, 6 ~ 8S) → kuaj xyuas cov khoom thauj → kev thauj khoom.
Ua lub hauv paus ua ntej, thiab tom qab ntawd npog cov txheej txheem foaming:
Tes ntawv: npaj cov khoom xyaw, npaj, tsheb ciav hlau, npaj luam ntawv ua ntej kev tsim khoom) → daim ntaub npog → hauv paus roj hmab (2 ~ 3 zaug) → tshuab kom qhuav → npog nto (3 txog 4 zaug) → tshuab kom qhuav (qhov kub yuav tsum yog, Ua tsis ua npuas dej) → Ua kom kub dua (160 ~ 180 ℃) → Kev soj ntsuam cov khoom lag luam → Kev xa khoom.
Tshuab luam ntawv: Kev npaj ua ntej ua tiav (sib xyaw, npaj, kev cob qhia, npaj cov ntawv luam tawm) → nthuav tawm → roj hmab primer (2 mus rau 3 zaug, ziab tib lub sijhawm) → npog (2
mus rau 3 zaug, ziab ib lub sijhawm) → Kev kub siab dhau los (160 ~ 180 ℃) → kuaj xyuas → cov zaub mov xa tuaj
