Kev Ntsuas Khoom Noj & Dej Haus
Kev ua kom cov khoom noj muaj zog txhais tau tias tshem tawm ib feem ntawm cov kuab tshuaj ntawm cov khoom noj ua kua kom zoo dua qub, khaws cia thiab thauj mus los. Nws tuaj yeem muab faib ua kev ua kom qhuav thiab kev ua kom khov.
Kev Ntsuas Ua Pa
Kev ua kom cov dej noo ua haujlwm raws li qhov sib txawv ntawm cov kuab tshuaj thiab cov kuab tshuaj. Thaum qhov kev hloov pauv ntawm cov kuab tshuaj hauv cov tshuaj me me thiab cov kuab tshuaj muaj qhov kev hloov pauv pom tseeb, cov kuab tshuaj raug ua kom sov los ntawm kev ua kom cov tshuaj sib xyaw. Cov kua zaub mov uas yuav tsum tau ua kom sib xyaw raug muab tso rau hauv lub tshuab ua kom sov thiab cua sov los ntawm qhov chaw cua sov sab nraud. Thaum qhov kub nce siab, cov kuab tshuaj (dej) hauv cov tshuaj yuav hloov mus ua pa, vim tias qhov kub ntawm dej yog qis thiab nws yooj yim ua kom pa.
Thaum lub sijhawm ua kom cov kua dej noo, cov pa dej uas ua rau cov tshuaj yaj tawm mus tas li, thaum cov tshuaj yaj (xws li qab zib, protein, cov zaub mov, cov vitamins, cov xim thiab lwm yam khoom uas tsis yaj lossis nyuaj yaj) tseem nyob hauv cov tshuaj seem vim nws lub ntsiab lus kub dua thiab qhov tsis yaj. Cov pa dej uas yaj lawm ces raug sau thiab txias los ntawm lub tshuab condenser kom hloov nws rov qab mus ua kua. Cov txheej txheem no tuaj yeem rov qab tau qee lub zog thiab txo kev siv zog. Cov dej uas yaj tuaj yeem rov ua dua lossis tso tawm.
Cov kua thawj zaug raug muab sib xyaw ua ke me dua tom qab ua pa thiab ua kom dej noo ua rau cov kua ntau ntxiv. Cov kua zaub mov sib xyaw ua ke no siv tau rau kev ua tom qab, xws li ziab ntxiv, ua khoom qab zib, ua jams, kua txiv hmab txiv ntoo, lossis ua cov khoom siv raw nruab nrab rau kev tsim khoom noj.
Feem ntau siv cov txheej txheem ntau theem lossis ntau yam txiaj ntsig ntawm kev ua kom cov khoom noj sib xyaw thiab sib sau ua ke hauv kev lag luam. Raws li qhov xav tau ntawm cov txheej txheem tsim khoom tshwj xeeb, kev ntsuas cov khoom noj kom raug raws sijhawm kom ntseeg tau tias cov khoom zoo ruaj khov thiab txhim kho kev ua haujlwm ntawm kev sib sau ua ke.Lonnmeter, ib lub chaw muag khoom ntsuas concentration hauv online, kom paub ntau ntxivlub ntsuas concentration hauv onlinecov kev daws teeb meem.
Cov yam ntxwv tseem ceeb ntawm kev ua kom qhuav thiab kev sib sau ua ke
Yuav tsum xav txog qhov kub thiab lub sijhawm ua kom sov thaum ua kom cov khoom noj thiab dej haus yaj. "Kub tsawg thiab lub sijhawm luv" yog qhov tseem ceeb kom ntseeg tau tias cov khoom noj zoo li cas, thaum "kub siab thiab lub sijhawm luv" yog qhov tseem ceeb kom txhim kho kev ua haujlwm ntawm cov khoom.
Kev kub dhau heev yuav ua rau cov protein, qab zib thiab pectin puas tsuaj, tawg thiab sib sau ua ke. Cov khoom siv ua tiav uas kov ze rau qhov chaw hloov pauv cua sov yuav ua rau muaj kev nce siab rau qhov kub siab tshaj plaws, piv rau qhov kub ib puag ncig ntawm cov khoom. Thaum muaj kev nce siab, nws yuav cuam tshuam loj heev rau kev ua haujlwm ntawm kev hloov pauv cua sov thiab txawm tias ua rau muaj teeb meem kev nyab xeeb. Kev ntsuas zoo los daws qhov teeb meem kev nce siab yog kom nce qhov ceev ntawm cov kua. Kev paub dhau los tau qhia tias kev nce qhov ceev ntawm cov kua tuaj yeem txo qhov kev tsim ntawm cov nplai. Tsis tas li ntawd, cov txheej txheem tiv thaiv electromagnetic thiab tshuaj tiv thaiv kev nce siab tuaj yeem siv los tiv thaiv kev nce siab.
Qhov viscosity
Muaj ntau yam khoom noj uas muaj cov protein ntau, qab zib, pectin thiab lwm yam khoom xyaw uas muaj viscosity siab. Thaum lub sijhawm ua kom cov kua dej noo, qhov viscosity ntawm cov kua dej yuav nce ntxiv nrog rau qhov concentration thaum cov kua dej tsawg zuj zus, uas ua rau cov cua sov tsis ua haujlwm zoo. Yog li ntawd, rau kev ua kom cov khoom viscous noo, kev ncig lossis kev sib xyaw ua ke uas yuam los ntawm lub zog sab nraud feem ntau yog siv.
Kev ua npuas dej tau
Cov khoom noj uas muaj protein ntau dua muaj qhov nro ntawm qhov chaw ntau dua. Thaum ua pa thiab npau, muaj cov ua npuas dej ruaj khov dua, uas yooj yim ua rau cov kua nkag mus rau hauv lub condenser nrog lub pa dej, ua rau cov kua poob. Kev tsim ua npuas dej muaj feem cuam tshuam nrog kev nruj ntawm qhov chaw. Kev nruj ntawm qhov chaw tshwm sim ntawm lub pa dej, cov kua kub heev thiab cov khoom khov uas raug tshem tawm, thiab cov khoom khov ua lub luag haujlwm tseem ceeb hauv kev tsim ua npuas dej. Feem ntau, surfactants tuaj yeem siv los tswj kev tsim ua npuas dej, thiab ntau yam khoom siv kho tshuab kuj tuaj yeem siv los tshem tawm ua npuas dej.
Kev xeb
Qee cov khoom noj uas muaj kua qaub, xws li kua zaub thiab kua txiv hmab txiv ntoo, yuav ua rau lub evaporator xeb thaum lub sijhawm ua pa thiab ua kom sib xyaw. Rau cov khoom noj, txawm tias qhov xeb me me feem ntau ua rau muaj kev ua qias tuaj uas ua rau cov khoom tsis tsim nyog. Yog li ntawd, lub evaporator siv rau cov khoom noj uas muaj kua qaub yuav tsum tau ua los ntawm cov khoom siv tiv taus xeb thiab ua kom sov tau, thiab cov qauv tsim yuav tsum yooj yim hloov. Piv txwv li, qhov sib xyaw ntawm cov kua qaub citric acid tuaj yeem siv cov raj cua sov graphite impermeable lossis cov evaporators sandwich enamel uas tiv taus kua qaub.
Cov Khoom Uas Hloov Tau Ntau yam khoom noj uas ua kua muaj cov khoom tsw qab thiab cov khoom qab, uas hloov tau ntau dua li dej. Thaum cov kua ua pa, cov khoom no yuav tawm nrog cov pa dej, cuam tshuam rau qhov zoo ntawm cov khoom uas muaj zog. Txawm hais tias qhov kev sib xyaw ua ke ntawm qhov kub qis tuaj yeem txo qhov poob ntawm cov khoom qab, ib txoj hauv kev zoo dua yog siv cov kev ntsuas rov qab thiab tom qab ntawd ntxiv rau hauv cov khoom tom qab rov qab.
Kev Ntsuas Khov
Cov kua zaub mov ua los ntawm cov khoom siv raw (xws li kua txiv hmab txiv ntoo, cov khoom noj mis nyuj lossis lwm yam kua uas muaj dej ntau) raug txias rau hauv qhov chaw kub qis. Thaum qhov kub poob qis dua qhov khov, cov dej hauv cov kua yuav poob rau hauv daim ntawv ntawm cov dej khov. Qhov no yog vim tias dej ncav cuag qhov sib npaug ntawm cov khoom khov thiab kua ntawm qhov kub thiab siab tshwj xeeb. Hauv qab qhov kub no, cov dej dawb ntau dhau yuav khov ua ntej, thaum cov khoom yaj (xws li qab zib, cov organic acids, cov xim, cov tsw qab, thiab lwm yam) tsis yooj yim khov nrog dej vim muaj kev yaj sib txawv, tab sis tseem nyob hauv cov khoom tsis khov.
Kev Sib Cais Cov Pob Zeb Dej Khov
Cov dej khov uas tsim tau raug cais tawm ntawm cov khoom sib xyaw los ntawm kev centrifugation, filtration lossis lwm txoj kev siv lub cev. Cov txheej txheem no tsis cuam tshuam rau kev ua kom cov solute evaporation, yog li nws tuaj yeem tiv thaiv kev puas tsuaj ntawm cov khoom xyaw uas rhiab heev rau cua sov thiab poob ntawm aroma. Cov concentrate tom qab cais cov dej khov crystals yog cov khoom khov concentration, uas muaj cov solute concentration siab dua li cov kua thawj, thaum khaws cov xim qub, saj, cov khoom noj khoom haus thiab saj ntawm cov zaub mov kom zoo tshaj plaws.
Kev Tswj Xyuas Cov Xwm Txheej Khov
Thaum lub sijhawm ua cov txheej txheem khov, cov yam xws li qhov ceev khov, qhov kub khov thiab lub sijhawm yuav tsum tau tswj kom meej kom zoo tshaj plaws qhov loj ntawm cov dej khov, morphology thiab kev sib cais ntawm cov concentrate kom ntseeg tau tias qhov zoo ntawm cov khoom kawg. Cov txheej txheem khov concentration yog qhov tsim nyog tshwj xeeb rau cov khoom noj thiab dej haus uas rhiab heev rau cua sov, xws li cov txiv hmab txiv ntoo tshiab thiab kua zaub, cov khoom siv biological, tshuaj thiab cov khoom noj khoom haus zoo. Nws tuaj yeem ua kom zoo tshaj plaws ntawm cov khoom siv raw thiab muaj cov yam ntxwv ntawm kev txuag hluav taws xob thiab kev ua haujlwm zoo. Txawm li cas los xij, txoj kev no kuj muaj qee qhov kev txwv. Piv txwv li, cov txheej txheem concentration tsis tuaj yeem ua kom huv si thiab yuav xav tau kev kho mob ntxiv. Tsis tas li ntawd, rau qee cov tshuaj uas muaj viscosity siab lossis muaj cov khoom xyaw tshwj xeeb, qhov nyuaj ntawm kev sib cais cov dej khov crystals ntawm cov concentrate yuav nce ntxiv, ua rau kev ua haujlwm concentration txo qis thiab cov nqi nce ntxiv.
