Ph meter kuj tuaj yeem ntsuas cov txiv hmab txiv ntoo
1. Yam pH meter yuav tsum tau siv rau kev ntsuas txiv hmab txiv ntoo
Txij li cov jams, jellies thiab kua txiv hmab txiv ntoo thiab lwm yam muaj cov kev xav tau zoo thiab zoo ib yam, nws yog ib qho tseem ceeb kom muaj pH tswj hauv cov txheej txheem no. Flavor, xim thiab stability yog qhov tseem ceeb hauv kev txiav txim siab zoo. pH cuam tshuam gelling, tsw thiab txee lub neej ntawm cov khoom. Feem ntau, kev sib ntxiv ntawm cov kua qaub (xws li lactic acid) yog siv los txo cov pH. Nyob ntawm seb muaj pes tsawg cov teeb meem uas muaj, pectin tsuas yog tsim colloids nyob rau hauv ib qho pH ntau yam. Yog li ntawd, thaum lub sij hawm zus tau tej cov jams, jellies thiab kua txiv, ntxiv ntawm edible acids yog tswj los ntawm online pH ntsuas. Cov txheej txheem no tuaj yeem ua kom qhov tseeb ntawm kev tsim khoom thiab paub txog cov txheej txheem automation.
2. Kev ntsuas ntawm PH acidity meter
Ua ntej, cov khoom xyaw hauv paus (xws li: txiv hmab txiv ntoo thiab qab zib) yog tov thiab pasteurized ntawm 105C (220F). Tag nrho feem ntau yog 60-65 feem pua qab zib thiab qee zaum txiv hmab txiv ntoo granules. Tom qab txias, cov khoom xyaw no raug xa mus rau lub tank ua noj thaum cov khoom ntxiv xws li cov txuj lom, pectin thiab cov khoom noj acids ntxiv rau hauv lub thawv kaw thaum nplawm ntawm 80 txog 100 C (176-212 F), 1.2 txog 1.3 bar ({{ 10}} psi). pre-mixer. Cov txheej txheem siab thiab kub nyob ntawm seb lub nkoj loj, qhov chaw teeb tsa thiab cov khoom. Ntxiv cov zaub mov acid kom txog thaum pH nce mus txog qhov xav tau. Feem ntau pH yog 2.8-3.2 (txiav txim siab los ntawm cov khoom). Thaum ua noj, kev tswj pH tas li yog ua los kho tus nqi ntawm cov khoom noj acid ntxiv. Yog tias pH qis dhau (piv txwv li: txiv apple pectin <2.8), pectin pib tawv, ua nkig thiab tsim ntxov ntxov. Yog tias nws siab tshaj pH ntau yam, nws tsis tuaj yeem tsim cov gel.
3. Yuav ua li cas rau nruab lub ntsuas pH
Rau kev ntsuas pH hauv jams, jellies thiab kua txiv, cov qauv hauv qab no tau pom zoo:
a) PH acidity meter sab installation:
Composite pH electrode: HA405-DPA-SC-S8/225 nrog nyiaj ion ntxiab
Sheath: retractable InTrac777, H=70mm, retractable manually los yog pneumatically. Cov cuab yeej no tso cai rau cov electrodes kom thim rov qab rau hauv lub tshuab ntxhua khaub ncaws kom ntxuav thiab tshem tawm kom tsis txhob cuam tshuam cov txheej txheem ntau lawm.
b) PH acidity meter sab installation:
Composite pH electrode: HA405-DPA-SC-S8/120 nrog nyiaj ion ntxiab
Sheath: InFit 761-50CIP/70
c) Pom zoo transmitter rau PH acidity meter: 2500 nrog Sensocheck, uas tuaj yeem txheeb xyuas cov teeb meem ntawm electrode (piv txwv li: electrode puas). Kev ntsuas cov ntaub ntawv tuaj yeem xa ncaj qha mus rau lub computer tswj system. Kev saib xyuas qis pH electrode HA405-DPA-SC-S8. Cov gel electrode no yog pre-pressurized rau 2.5 bar (36psi), yog li tsis zoo li kua electrolyte electrodes, nws yuav tsum tau siv nrog ib tug pressurized sheath.
Nws kuj tuaj yeem ntsuas cov txiv hmab txiv ntoo. Nws tuaj yeem pom tias Ph acidity meter tuaj yeem ua lub luag haujlwm hauv txhua yam ntawm kev txhim kho yav tom ntej, thiab nws txoj haujlwm muaj zog.
