Dab tsi yog qhov sib txawv ntawm lub ntsuas suab thaj digital thiab lub ntsuas hluav taws xob ntawm tes?
Cov ntsuas suab thaj digital yog siv los ntsuas qhov ntsuas nrawm lossis ntsuas qhov ntsuas ntawm cov piam thaj uas muaj cov piam thaj thiab lwm yam tsis muaj qab zib. Nws yog dav siv hauv qab zib, khoom noj khoom haus, dej haus thiab lwm yam kev lag luam, nrog rau kev ua liaj ua teb thiab kev tshawb fawb tshawb fawb. Nws yog qhov tsim nyog rau kev ntsuas ntsuas ntawm ntau yam ntses (seasoning) cov khoom xws li kua ntses thiab ketchup; nws yog qhov tsim nyog rau kev ntsuas cov piam thaj hauv cov khoom uas muaj cov ntsiab lus qab zib xws li jam, qab zib diluted qab zib, thiab lwm yam; nws yog tsim rau cov kab ntau lawm ntawm cov kua txiv hmab txiv ntoo, refreshing dej qab zib thiab carbonated dej qab zib. Kev tswj xyuas zoo, kev tshuaj xyuas ua ntej ua zaub mov xa tuaj, thiab lwm yam .; haum rau cov txheej txheem los ntawm cog mus rau kev muag khoom ntawm txiv hmab txiv ntoo. Nws tuaj yeem siv los txiav txim siab lub sijhawm sau qoob loo kom raug thiab faib cov khoom qab zib. Tsis tas li ntawd, kev txiav txim siab concentration ntawm slurries hauv kev lag luam textile kuj tau siv dav.
Lub hauv paus ntsiab lus tsim ntawm lub ntsuas qab zib: thaum lub teeb nkag los ntawm ib qho nruab nrab mus rau lwm qhov nruab nrab, qhov cuam tshuam tshwm sim, thiab qhov sib piv ntawm qhov sib piv ntawm qhov xwm txheej ntawm lub kaum sab xis yog tas li. Qhov piv no yog hu ua refractive index. Cov ntsiab lus soluble nyob rau hauv cov txiv hmab txiv ntoo thiab zaub kua txiv yog ncaj qha proportional rau lub refractive index nyob rau hauv tej yam kev mob (tib yam kub thiab siab). Yog li ntawd, los ntawm kev ntsuas qhov ntsuas qhov ntsuas ntawm cov kua txiv hmab txiv ntoo thiab zaub, qhov concentration (qab zib cov ntsiab lus) ntawm cov txiv hmab txiv ntoo thiab zaub kua txiv tuaj yeem pom. Cov cuab yeej siv feem ntau yog handheld refractometers, tseem hu ua iav qab zib thiab handheld qab zib ntsuas. Los ntawm kev ntsuas cov ntsiab lus soluble (qab zib) ntawm cov txiv hmab txiv ntoo thiab zaub, qhov zoo ntawm cov txiv hmab txiv ntoo thiab zaub tuaj yeem nkag siab thiab kev loj hlob ntawm cov txiv hmab txiv ntoo tuaj yeem kwv yees kwv yees. Ib tug handheld qab zib meter feem ntau yog cylindrical. Muab cov kua qab zib ntsuas rau hauv lub qhov uas tuaj yeem qhib rau tom qab, kis nws tusyees, kaw lub hau, tom qab ntawd tuav lub ntsuas qab zib mus rau lub teeb thiab saib lub qhov nyob rau hauv pem hauv ntej nyeem.
Qhov txawv ntawm cov ntsuas qab zib digital thiab handheld refractometer:
Digital Sus meter:
Cov ntsuas suab thaj digital yog siv los ua kom yooj yim thiab nrawm txiav txim siab qhov hnyav feem pua ntawm qhov hnyav lossis qhov ntsuas qhov ntsuas ntawm cov piam thaj uas muaj cov tshuaj. Nws yog dav siv hauv qab zib, khoom noj khoom haus, dej haus thiab lwm yam kev lag luam, nrog rau kev ua liaj ua teb thiab kev tshawb fawb tshawb fawb.
Lub hauv paus ntsiab lus ua haujlwm: Lub ntsuas qab zib feem ntau yog siv qhov tshwm sim ntawm qhov cuam tshuam thaum lub teeb nkag los ntawm ib qho nruab nrab mus rau lwm qhov nruab nrab, thiab qhov sib piv ntawm sine ntawm lub kaum sab xis ntawm qhov xwm txheej yog tas li. Qhov piv no yog hu ua refractive index. Siv lub fact tias cov ntsiab lus ntawm soluble tshuaj nyob rau hauv cov kua qab zib yog ncaj qha proportional rau lub refractive index nyob rau hauv tej yam kev mob, lub refractive index ntawm cov kua qab zib yuav raug ntsuas, kom lub qab zib meter / refractometer yuav xam cov concentration ntawm qab zib.
Handheld Refractometer
Lub handheld refractometer yog ib qho cuab yeej uas tuaj yeem ntsuas qhov ntsuas refractive nD thiab qhov nruab nrab dispersion nF-nC ntawm cov pob tshab, cov kua nplaum los yog cov khoom khib nyiab (tsuas yog ntsuas cov kua pob tshab). Yog tias lub ntsuas kub txuas nrog lub ntsuas ntsuas, qhov ntsuas qhov ntsuas qhov ntsuas ND tuaj yeem ntsuas nyob rau hauv qhov ntsuas kub ntawm 0 txog 70. Refractive Performance index thiab qhov nruab nrab dispersion yog ib qho tseem ceeb ntawm cov khoom siv kho qhov muag, uas tuaj yeem siv tau. nkag siab txog cov khoom kho qhov muag, purity, concentration thiab dispersion loj ntawm cov khoom. Vim hais tias lub handheld refractometer tuaj yeem ntsuas qhov concentration feem pua ntawm cov piam thaj hauv cov tshuaj sucrose, lub handheld refractometer yog siv dav hauv kev lag luam roj av, kev lag luam roj, kev lag luam xim, kev lag luam zaub mov, kev lag luam tshuaj txhua hnub, thiab kev lag luam qab zib. Nws yog ib qho ntawm cov khoom siv tsis tseem ceeb hauv cov chaw tsim khoom, tsev kawm ntawv thiab cov chaw tshawb fawb txog kev lag luam thiab kev tshawb fawb geological.
