Dab tsi yog qhov txawv ntawm lub ntsuas suab thaj digital thiab lub ntsuas tes tuav refractometer?
Digital Brix Meter yog siv los ntsuas qhov concentration lossis refractive Performance index ntawm cov tshuaj qab zib thiab lwm yam tshuaj uas tsis yog qab zib. Siv dav hauv qab zib, zaub mov, 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) khoom xws li kua ntses thiab lws suav sauce; nws yog qhov tsim nyog rau kev ntsuas cov piam thaj cov ntsiab lus ntawm cov khoom uas muaj suab thaj ntau xws li jam, syrup thiab kua qab zib; 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 xa khoom, thiab lwm yam .; haum rau cov txheej txheem ntawm cov txiv hmab txiv ntoo los ntawm kev cog rau kev muag khoom, nws tuaj yeem siv los txiav txim siab lub sijhawm sau qoob loo, thiab faib cov khoom qab zib. Tsis tas li ntawd, kev txiav txim siab ntawm qhov concentration ntawm pulp hauv kev lag luam textile kuj tau siv dav.
Lub hauv paus ntsiab lus tsim ntawm lub ntsuas qab zib: thaum lub teeb nkag mus rau lwm qhov nruab nrab ntawm ib qho nruab nrab, qhov cuam tshuam tshwm sim, thiab qhov sib piv ntawm qhov sib piv ntawm qhov teeb meem ntawm lub kaum sab xis yog qhov tsis tu ncua, thiab qhov piv no yog hu ua qhov ntsuas qhov taw qhia. Cov ntsiab lus ntawm soluble solids nyob rau hauv 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 cov concentration (qab zib ntsiab lus) ntawm txiv hmab txiv ntoo thiab zaub kua txiv tuaj yeem tau los ntawm kev ntsuas qhov ntsuas qhov ntsuas ntawm cov txiv hmab txiv ntoo thiab zaub kua txiv. Cov cuab yeej siv feem ntau yog hand-held refractometers, tseem hu ua iav qab zib thiab tes tuav cov ntsuas qab zib. Los ntawm kev ntsuas cov ntsiab lus soluble (qab zib) ntawm cov txiv hmab txiv ntoo thiab zaub, cov txiv hmab txiv ntoo thiab zaub zoo tuaj yeem nkag siab, thiab kev loj hlob ntawm cov txiv hmab txiv ntoo tuaj yeem kwv yees kwv yees. Lub tes tuav qab zib ntsuas feem ntau yog cylindrical. Muab cov kua qab zib tso rau hauv lub tank qhib rau tom qab, so nws sib npaug, kaw lub hau, thiab tom qab ntawd taw tes rau lub ntsuas qab zib rau lub teeb, thiab nyeem nws los ntawm lub qhov hauv ntej.
Qhov sib txawv ntawm cov ntsuas suab thaj digital thiab tes tuav refractometer:
1. Digital qab zib cov ntsiab lus ntsuas:
Cov khoom siv ntsuas suab thaj digital yog siv los txiav txim siab qhov hnyav feem pua ntawm cov piam thaj los yog qhov ntsuas qhov ntsuas pom hauv cov ntsiab lus qab zib. Siv dav hauv qab zib, zaub mov, 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 ntawm kev ua haujlwm: Lub ntsuas suab thaj feem ntau yog siv qhov tshwm sim ntawm qhov tshwm sim thaum lub teeb nkag mus rau lwm qhov nruab nrab ntawm ib qho nruab nrab, thiab qhov sib piv ntawm sine ntawm lub kaum sab xis ntawm qhov xwm txheej yog qhov tsis tu ncua, thiab qhov piv no yog hu ua refractive index. Lub refractive Performance index ntawm cov kua qab zib tuaj yeem ntsuas tau los ntawm kev siv qhov sib piv ncaj qha ntawm cov ntsiab lus ntawm cov tshuaj soluble hauv cov kua qab zib thiab cov refractive index nyob rau hauv cov xwm txheej zoo tib yam, kom cov piam thaj concentration tuaj yeem xam los ntawm cov ntsuas qab zib / refractometer.
2. Handheld refractometer
Handheld refractometer yog ib qho cuab yeej uas muaj peev xwm ntsuas qhov ntsuas qhov taw qhia nD thiab qhov nruab nrab dispersion nF-nC ntawm cov pob tshab, cov kua dej los yog cov khib nyiab (ntawm lawv, cov kua pob tshab feem ntau yog siv). Yog tias lub ntsuas ntsuas txuas nrog lub ntsuas kub, nws tuaj yeem ntsuas qhov ntsuas qhov ntsuas qhov ntsuas ND hauv qhov ntsuas kub ntawm 0 ~ 70. Refractive index thiab nruab nrab dispersion yog ib qho tseem ceeb ntawm cov khoom siv kho qhov muag, uas tuaj yeem siv los nkag siab txog cov khoom siv kho qhov muag, purity, concentration thiab dispersion ntawm cov khoom. Vim tias lub ntsuas ntsuas tes tuav tau ntsuas qhov feem pua ntawm cov ntsiab lus qab zib hauv cov tshuaj sucrose, lub tes tuav refractometer yog siv rau ntau yam kev siv. Nws yog ib qho ntawm cov khoom siv tsis tseem ceeb thiab feem ntau siv rau cov chaw tsim khoom, tsev kawm ntawv thiab cov chaw tshawb fawb xws li kev tshawb fawb txog kev lag luam thiab geological.
