Kev Tsim Khoom Margarine

Margarine thiab cov khoom muaj feem xyuam muaj cov dej thiab cov rog thiab yog li ntawd tuaj yeem piav qhia tias yog cov dej hauv roj (W/O) emulsions uas cov dej tau tawg ua cov tee dej me me hauv cov rog tas mus li. Nyob ntawm seb cov khoom siv li cas, cov khoom sib xyaw ntawm cov rog thiab cov txheej txheem tsim khoom raug xaiv raws li qhov ntawd.

Sib nrug ntawm cov khoom siv crystallization, lub chaw tsim khoom niaj hnub rau margarine thiab cov khoom lag luam cuam tshuam feem ntau yuav muaj ntau lub tank rau khaws roj nrog rau emulsifier, dej theem thiab emulsion npaj; qhov loj me thiab tus lej ntawm cov tank raug suav raws li lub peev xwm ntawm lub Hoobkas thiab cov khoom lag luam. Lub chaw kuj suav nrog chav pasteurization thiab chaw rov yaj. Yog li, cov txheej txheem tsim khoom feem ntau tuaj yeem faib ua cov txheej txheem hauv qab no (thov saib daim duab 1):

KEV NPAJ NTAWM THEEM DEJ THIAB THEEM ROG (CHEEB TSAM 1)

Cov dej feem ntau raug npaj ua ntu zus hauv lub thawv dej. Cov dej yuav tsum haus tau zoo. Yog tias tsis tuaj yeem lav tau tias cov dej haus zoo, cov dej yuav raug kho ua ntej los ntawm kev siv lub tshuab UV lossis lub tshuab lim dej.

Sib nrug ntawm cov dej, cov dej theem tuaj yeem muaj ntsev lossis brine, cov protein mis nyuj (cov margarine hauv rooj thiab cov roj tsawg), qab zib (puff pastry), stabilizers (cov roj tsawg thiab cov roj tsawg), preservatives thiab cov tsw qab uas yaj hauv dej.

Cov khoom xyaw tseem ceeb hauv theem rog, cov rog sib xyaw, feem ntau muaj cov rog thiab roj sib xyaw ua ke. Yuav kom tau cov margarine nrog cov yam ntxwv thiab kev ua haujlwm raws li xav tau, qhov sib piv ntawm cov rog thiab roj hauv cov rog sib xyaw yog qhov tseem ceeb rau kev ua haujlwm ntawm cov khoom kawg.

Cov rog thiab roj sib txawv, txawm tias yog cov roj sib xyaw lossis cov roj ib leeg, raug khaws cia rau hauv cov thoob roj uas feem ntau muab tso rau sab nraum qhov chaw tsim khoom. Cov no raug khaws cia rau qhov kub thiab txias ruaj khov saum qhov chaw yaj ntawm cov rog thiab raug sib xyaw kom tsis txhob muaj kev sib cais ntawm cov rog thiab kom yooj yim tuav.

Sib nrug ntawm cov rog sib xyaw, cov rog feem ntau muaj cov khoom xyaw me me uas yaj tau hauv cov rog xws li emulsifier, lecithin, tsw qab, xim thiab antioxidants. Cov khoom xyaw me me no raug yaj rau hauv cov rog sib xyaw ua ntej ntxiv cov dej, yog li ua ntej cov txheej txheem emulsification.

KEV NQIS EMULSION (CHEEB TSAM 2)

 Daim Duab 1:

1. Kev npaj theem dej thiab theem rog (cheeb tsam 1),

2. Kev npaj emulsion (cheeb tsam 2),

3. Kev ua kom sov (cheeb tsam 3),

4. Thaj chaw txias, crystallization thiab kneading (cheeb tsam 4),

5. Ntim thiab rov yaj (cheeb tsam 5)

Cov emulsion no yog npaj los ntawm kev hloov ntau yam roj thiab cov rog lossis cov rog sib xyaw rau hauv lub tank emulsion. Feem ntau, cov rog yaj siab lossis cov rog sib xyaw raug ntxiv ua ntej ua raws li cov rog yaj qis dua thiab cov roj ua kua. Txhawm rau kom tiav qhov kev npaj ntawm theem rog, cov emulsifier thiab lwm cov khoom xyaw me me uas yaj tau roj raug ntxiv rau hauv cov rog sib xyaw. Thaum tag nrho cov khoom xyaw rau theem rog tau sib xyaw kom zoo, theem dej raug ntxiv thiab cov emulsion raug tsim nyob rau hauv kev sib xyaw ua ke tab sis tswj tau.

Muaj ntau lub tshuab sib txawv siv tau rau kev ntsuas cov khoom xyaw sib txawv rau cov emulsion uas ob qho ua haujlwm ua ke:

1. Lub tshuab ntsuas dej ntws
2. Lub cev hnyav

Ib lub tshuab emulsification uas txuas ntxiv mus tas li yog ib qho kev daws teeb meem uas tsis tshua nyiam tab sis siv rau hauv cov kab uas muaj peev xwm loj uas muaj qhov chaw txwv rau cov thoob dej emulsion. Lub tshuab no siv cov twj dosing thiab cov ntsuas dej ntws los tswj qhov sib piv ntawm cov theem ntxiv rau hauv lub thoob dej emulsion me me.

Cov tshuab uas tau hais los saum toj no tuaj yeem tswj tau tag nrho yam tsis tas siv neeg. Txawm li cas los xij, qee lub Hoobkas qub tseem muaj cov tshuab ua emulsion uas tswj tau tes tab sis cov no siv zog ua haujlwm ntau thiab tsis pom zoo kom teeb tsa niaj hnub no vim yog cov cai nruj heev.

Lub tshuab ntsuas dej ntws yog ua raws li kev npaj emulsion ua pawg uas ntau theem thiab cov khoom xyaw raug ntsuas los ntawm cov ntsuas dej ntws thaum hloov los ntawm ntau theem npaj cov thoob dej mus rau hauv lub thoob dej emulsion. Qhov tseeb ntawm lub tshuab no yog +/- 0.3%. Lub tshuab no yog tus cwj pwm los ntawm nws txoj kev tsis hnov ​​​​​​mob rau cov kev cuam tshuam sab nraud xws li kev co thiab av qias neeg.

Lub tshuab ntsuas qhov hnyav zoo li lub tshuab ntsuas dej ntws uas ua raws li kev npaj emulsion raws li pawg. Ntawm no cov khoom xyaw thiab cov theem raug ntxiv ncaj qha rau hauv lub tank emulsion uas tau teeb tsa rau ntawm cov hlwb thauj khoom tswj cov khoom ntxiv rau hauv lub tank.

Feem ntau, siv ob lub tank los npaj cov emulsion kom thiaj li khiav tau cov kab crystallization tas mus li. Txhua lub tank ua haujlwm ua lub tank npaj thiab buffer (emulsion tank), yog li ntawd cov kab crystallization yuav raug pub los ntawm ib lub tank thaum ib pawg tshiab yuav raug npaj rau lwm qhov thiab rov qab los. Qhov no hu ua flip-flop system.

Ib qho kev xaiv yog ib qho kev daws teeb meem uas cov emulsion raug npaj rau hauv ib lub tank thiab thaum npaj tiav lawm ces raug xa mus rau lub buffer tank uas cov kab crystallization raug pub. Lub kaw lus no hu ua premix/buffer system.

KUA TXOB (CHEEB TSAM 3)

Los ntawm lub tank buffer, cov emulsion feem ntau raug pumped tas li los ntawm lub phaj cua sov exchanger (PHE) lossis lub siab qis scraped surface heat exchanger (SSHE), lossis siab siab SSHE rau pasteurization ua ntej nkag mus rau hauv kab crystallization.

Rau cov khoom muaj roj ntau, feem ntau siv PHE. Rau cov roj tsawg dua qhov twg cov emulsion yuav tsum muaj viscosity siab thiab rau cov emulsions uas sov tau (piv txwv li emulsions nrog cov protein ntau) lub kaw lus SPX ua cov kua qis lossis SPX-PLUS ua cov kua siab yog qhov pom zoo.

Cov txheej txheem pasteurization muaj ntau qhov zoo. Nws ua kom muaj kev tiv thaiv kev loj hlob ntawm cov kab mob thiab kev loj hlob ntawm lwm cov kab mob me me, yog li txhim kho qhov ruaj khov ntawm cov emulsion. Pasteurization ntawm cov dej theem tsuas yog qhov ua tau, tab sis pasteurization ntawm tag nrho cov emulsion yog qhov zoo dua vim tias cov txheej txheem pasteurization ntawm cov emulsion yuav txo lub sijhawm nyob los ntawm cov khoom pasteurized mus rau kev sau lossis ntim khoom kawg. Tsis tas li ntawd, cov khoom raug kho hauv cov txheej txheem hauv kab los ntawm pasteurization mus rau kev sau lossis ntim khoom kawg thiab pasteurization ntawm txhua yam khoom siv rov ua dua yog ua kom ntseeg tau thaum cov emulsion tiav lawm yog pasteurized.

Ntxiv mus, kev ua kom cov emulsion tiav lawm ua kom cov emulsion raug pub rau kab crystallization ntawm qhov kub tas li ua tiav cov txheej txheem ua tiav, qhov kub ntawm cov khoom thiab cov qauv ntawm cov khoom. Tsis tas li ntawd, qhov tshwm sim ntawm cov emulsion ua ntej crystallized pub rau cov khoom siv crystallization raug tiv thaiv thaum cov emulsion raug pasteurized kom zoo thiab pub rau lub twj tso kua mis siab ntawm qhov kub 5-10 ° C siab dua qhov melting point ntawm cov rog theem.

Ib qho txheej txheem pasteurization ib txwm yuav tom qab npaj cov emulsion ntawm 45-55 ° C suav nrog kev cua sov thiab tuav cov emulsion ntawm 75-85 ° C rau 16 vib nas this. thiab tom qab ntawd cov txheej txheem txias mus rau qhov kub ntawm 45-55 ° C. Qhov kub kawg nyob ntawm qhov melting point ntawm cov rog theem: qhov siab dua qhov melting point, qhov kub siab dua.

TXIAV, CRYSTALLIZATION THIAB KNEADING (CHILLING, CRYSTALLIZATION, THIAB KNEADING) (CHEEB TSAM 4)

 Cov emulsion raug pumped mus rau kab crystallization los ntawm kev siv lub twj tso kua mis siab (HPP). Kab crystallization rau kev tsim cov margarine thiab cov khoom lag luam cuam tshuam feem ntau muaj SSHE siab uas txias los ntawm ammonia lossis Freon hom txias. Cov tshuab Pin rotor thiab / lossis cov crystallizers nruab nrab feem ntau suav nrog hauv kab kom ntxiv qhov sib zog thiab lub sijhawm rau kev tsim cov khoom yas. Lub raj so yog kauj ruam kawg ntawm kab crystallization thiab tsuas yog suav nrog yog tias cov khoom tau ntim.

Lub plawv ntawm txoj kab crystallization yog lub siab SSHE, uas cov emulsion sov so yog super-txias thiab crystallized rau ntawm qhov chaw sab hauv ntawm lub raj txias. Cov emulsion raug scraped tawm zoo los ntawm cov scrapers tig, yog li cov emulsion txias thiab kneaded tib lub sijhawm. Thaum cov rog hauv cov emulsion crystallizes, cov rog crystals tsim ib lub network peb-seem encapring cov dej tee thiab cov roj kua, ua rau cov khoom muaj cov khoom ntawm cov yas semi-khoom.

Nyob ntawm hom khoom uas yuav tsim tawm thiab hom roj siv rau cov khoom tshwj xeeb, qhov kev teeb tsa ntawm cov kab crystallization (piv txwv li qhov kev txiav txim ntawm cov raj txias thiab cov tshuab pin rotor) tuaj yeem hloov kho kom muab qhov kev teeb tsa zoo tshaj plaws rau cov khoom tshwj xeeb.

Vim tias cov kab crystallization feem ntau tsim ntau dua ib yam khoom rog tshwj xeeb, SSHE feem ntau muaj ob lossis ntau qhov chaw txias lossis cov raj txias kom ua tau raws li qhov yuav tsum tau ua rau cov kab crystallization yooj ywm. Thaum tsim cov khoom rog crystallized sib txawv ntawm ntau yam sib xyaw rog, kev yooj ywm yog qhov xav tau vim tias cov yam ntxwv crystallization ntawm cov sib xyaw yuav txawv ntawm ib qho sib xyaw mus rau lwm qhov.

Cov txheej txheem crystallization, cov xwm txheej ua tiav thiab cov txheej txheem ua tiav muaj feem cuam tshuam loj heev rau cov yam ntxwv ntawm cov khoom margarine thiab cov khoom sib kis kawg. Thaum tsim cov kab crystallization, nws yog ib qho tseem ceeb kom txheeb xyuas cov yam ntxwv ntawm cov khoom npaj yuav tsim tawm ntawm kab.
