Lub chaw tseem muaj xws li chav tsev pasteurization thiab lub chaw remelting. Yog li, cov txheej txheem tsim khoom feem ntau tuaj yeem muab faib ua cov txheej txheem hauv qab no (thov saib daim duab 1):

KEV PAB CUAM NTAWM E WATER PHASE THIAB KEV PHEM (ZEEM 1)

Cov theem dej feem ntau yog npaj batch-wise nyob rau hauv cov dej theem tank. Cov dej yuav tsum yog cov dej haus zoo. Yog tias haus dej tsis zoo tuaj yeem lav tsis tau, cov dej tuaj yeem raug kho ua ntej los ntawm kev siv xws li UV lossis lim dej.

Sib nrug los ntawm cov dej, cov dej theem tuaj yeem muaj ntsev los yog brine, mis nyuj proteins (cov lus margarine thiab cov rog tsawg), qab zib (puff pastry), stabilizers (txo thiab tsis muaj roj kis), preservatives thiab dej-soluble flavors.

Cov khoom xyaw tseem ceeb hauv theem rog, cov rog sib xyaw, feem ntau muaj cov sib xyaw ntawm cov rog thiab cov roj sib txawv. Txhawm rau ua tiav margarine nrog cov yam ntxwv xav tau thiab kev ua haujlwm, qhov sib piv ntawm cov roj thiab cov roj hauv cov roj sib tov yog txiav txim siab rau kev ua haujlwm ntawm cov khoom kawg.

Cov roj ntau thiab roj, xws li roj sib xyaw lossis roj ib leeg, yog khaws cia hauv cov roj cia tank feem ntau muab tso rau sab nraum qhov chaw tsim khoom. Cov no tau khaws cia ntawm qhov ntsuas kub ruaj khov siab tshaj qhov melting point ntawm cov roj thiab nyob rau hauv agitation kom tsis txhob fractionation ntawm cov roj thiab cia yooj yim tuav.

Sib nrug los ntawm cov rog sib xyaw, cov roj theem feem ntau muaj cov khoom xyaw roj-soluble me xws li emulsifier, lecithin, tsw, xim thiab antioxidants. Cov khoom me me no tau yaj hauv cov roj sib xyaw ua ntej cov dej theem ntxiv, yog li ua ntej cov txheej txheem emulsification.

EMULSION Kev Npaj (ZONE 2)

Lub emulsion yog npaj los ntawm kev hloov ntau yam roj thiab roj los yog roj sib xyaw rau hauv lub tank emulsion. Feem ntau, cov roj melting siab lossis cov roj sib tov yog ntxiv ua ntej los ntawm cov roj melting qis thiab cov roj ua kua. Txhawm rau ua kom tiav qhov kev npaj ntawm cov roj theem, cov emulsifier thiab lwm cov khoom xyaw roj-soluble me yog ntxiv rau cov roj sib tov. Thaum tag nrho cov khoom xyaw rau theem rog tau raug muab sib xyaw kom zoo, cov theem dej ntxiv thiab cov emulsion yog tsim nyob rau hauv hnyav tab sis tswj kev sib xyaw.

Cov tshuab sib txawv tuaj yeem siv los ntsuas qhov sib txawv ntawm cov khoom xyaw rau emulsion uas ob ua haujlwm batch-wise:

Flow Meter system

Qhov hnyav tank system

Ib qho kev txuas ntxiv hauv-kab emulsification system yog qhov tsis nyiam tab sis siv cov tshuaj hauv xws li cov kab muaj peev xwm siab uas txwv qhov chaw rau emulsion tso tsheb hlau luam. Lub kaw lus no yog siv cov twj tso kua mis thiab cov ntsuas dej loj los tswj qhov sib piv ntawm cov theem ntxiv rau hauv lub tank me me emulsion.

Cov tshuab uas tau hais los saum toj no tuaj yeem tswj tau tag nrho. Qee cov nroj tsuag laus, txawm li cas los xij, tseem muaj cov txheej txheem tswj kev tswj hwm emulsion tab sis cov no yog cov neeg xav tau kev ua haujlwm thiab tsis pom zoo rau nruab hnub no vim yog cov cai nruj heev.

Flow meter system yog raws li kev npaj batch-wise emulsion nyob rau hauv uas ntau theem thiab cov khoom xyaw yog ntsuas los ntawm huab hwm coj ntsuas ntsuas thaum hloov los ntawm ntau theem npaj tso tsheb hlau luam rau hauv lub tank emulsion. Qhov tseeb ntawm qhov system no yog +/- 0.3%. Qhov system no yog tus cwj pwm los ntawm nws qhov tsis txaus ntseeg rau sab nraud cuam tshuam xws li kev vibrations thiab av.

Lub cev hnyav lub tank zoo li lub ntsuas dej ntws raws li kev npaj batch-wise emulsion. Ntawm no cov nqi ntawm cov khoom xyaw thiab cov theem yog ntxiv ncaj qha rau lub tank emulsion uas yog mounted rau load hlwb tswj cov nyiaj ntxiv rau lub tank.

Feem ntau, ob lub tank yog siv los npaj cov emulsion thiaj li yuav khiav tau cov kab crystallization tsis tu ncua. Txhua lub tank ua haujlwm raws li kev npaj thiab tsis tank (emulsion tank), yog li cov kab crystallization yuav raug pub los ntawm ib lub tank thaum lub batch tshiab yuav npaj rau lwm qhov thiab vice versa. Qhov no yog hu ua flip-flop system.

Ib qho kev daws teeb meem uas cov emulsion tau npaj rau hauv ib lub tank thiab thaum npaj tau hloov mus rau lub tank tsis los ntawm qhov chaw uas cov kab crystallization tau pub kuj yog ib qho kev xaiv. Qhov system no hu ua premix/buffer system.

PASTEURIZATION (ZONE 3)

Los ntawm lub tank buffer lub emulsion yog ib txwm tsis tu ncua pumped los ntawm ib tug phaj kub exchanger (PHE) los yog ib tug tsis tshua muaj siab scraped nto tshav kub exchanger (SSHE), los yog siab SSHE rau pasteurization ua ntej nkag mus rau hauv lub crystallization kab.

Rau cov khoom lag luam rog tag nrho PHE feem ntau yog siv. Rau cov roj qis dua qhov twg cov emulsion yuav tsum muaj cov viscosity siab heev thiab rau cov cua sov-sensible emulsions (xws li emulsions nrog cov ntsiab lus protein siab) SPX system raws li cov tshuaj tsis tshua muaj siab lossis SPX-PLUS raws li kev daws teeb meem siab.

Cov txheej txheem pasteurization muaj ntau qhov zoo. Nws ua kom inhibition ntawm cov kab mob kev loj hlob thiab kev loj hlob ntawm lwm cov kab mob, yog li txhim kho microbiological stability ntawm emulsion. Pasteurization ntawm cov dej theem tsuas yog ib qho ua tau, tab sis pasteurization ntawm tag nrho cov emulsion yog nyiam vim cov txheej txheem pasteurization ntawm emulsion yuav mini-mise lub sij hawm nyob los ntawm cov khoom pasteurized mus sau lossis ntim cov khoom kawg. Tsis tas li, cov khoom lag luam raug kho nyob rau hauv cov txheej txheem los ntawm pasteurization mus rau sau lossis ntim cov khoom kawg thiab pasteurization ntawm cov khoom siv rov ua dua tshiab tau lees paub thaum ua tiav emulsion yog pasteurized.

Tsis tas li ntawd, pasteurization ntawm tag nrho emulsion xyuas kom meej tias cov emulsion yog pub rau cov kab crystallization ntawm qhov kub thiab txias, ua tiav qhov kev ua haujlwm tas li, cov khoom kub thiab cov khoom zoo nkauj. Tsis tas li ntawd, qhov tshwm sim ntawm pre-crystallized emulsion pub rau cov khoom siv crystallization yog tiv thaiv thaum lub emulsion yog pasteurized zoo thiab pub rau lub twj tso kua mis siab ntawm qhov kub ntawm 5-10 ° C siab tshaj qhov melting point ntawm cov roj theem.

Cov txheej txheem pasteurization ib txwm yuav tom qab kev npaj ntawm emulsion ntawm 45-55 ° C suav nrog cua sov thiab tuav ib ntus ntawm emulsion ntawm 75-85 ° C rau 16 sec. Thiab tom qab ntawd cov txheej txheem txias rau qhov kub ntawm 45-55 ° C. Qhov kawg kub nyob ntawm qhov melting point ntawm cov roj theem: qhov siab dua qhov melting point, qhov kub thiab txias.

Lub emulsion yog pumped rau cov kab crystallization los ntawm kev siv lub twj tso kua mis siab piston (HPP). Cov kab crystallization rau kev tsim cov margarine thiab cov khoom muaj feem cuam tshuam feem ntau muaj lub siab SSHE uas yog txias los ntawm ammonia lossis Freon hom cua txias. Pin rotor tshuab (s) thiab/los yog nruab nrab crystallizers feem ntau muaj nyob rau hauv kab thiaj li yuav ntxiv kneading siv thiab sij hawm rau zus tau tej cov khoom yas. Lub raj so yog cov kauj ruam kawg ntawm cov kab crystallization thiab tsuas yog suav nrog yog tias cov khoom ntim khoom.

Lub plawv ntawm cov kab crystallization yog lub siab SSHE, uas lub emulsion sov yog super-cooled thiab crystallized nyob rau hauv lub puab nto ntawm lub chilling raj. Lub emulsion yog zoo scraped tawm los ntawm rotating scrapers, yog li lub emulsion yog chilled thiab kneaded ib txhij. Thaum cov roj nyob rau hauv emulsion crystallizes, cov roj muaju ua rau peb-dimensional network entrapping cov dej tee dej thiab cov roj ua kua, uas ua rau cov khoom uas muaj cov khoom ntawm cov khoom yas semi-solid xwm.

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

Txij li cov kab crystallization feem ntau tsim ntau dua ib qho khoom siv roj, SSHE feem ntau muaj ob lossis ntau qhov txias txias los yog chilling raj txhawm rau ua kom tau raws li qhov yuav tsum tau ua rau txoj kab hloov pauv crystallization. Thaum tsim cov khoom sib txawv crystallized rog ntawm ntau cov roj sib xyaw, kev hloov pauv yog xav tau vim tias cov yam ntxwv crystallization ntawm cov khoom sib txawv yuav txawv ntawm ib qho mus rau lwm qhov.

Cov txheej txheem crystallization, cov txheej txheem ua haujlwm thiab cov txheej txheem ua haujlwm muaj kev cuam tshuam zoo rau cov yam ntxwv ntawm qhov kawg margarine thiab cov khoom sib kis. Thaum tsim cov kab crystallization, nws yog ib qho tseem ceeb los txheeb xyuas cov yam ntxwv ntawm cov khoom uas tau npaj los tsim rau ntawm kab. Txhawm rau tiv thaiv kev nqis peev rau yav tom ntej, kev hloov pauv ntawm txoj kab nrog rau kev tswj hwm tus kheej ntawm tus kheej yog qhov tsim nyog, vim tias ntau yam ntawm cov khoom txaus siab yuav hloov nrog lub sijhawm thiab cov ntaub ntawv raw.

Lub peev xwm ntawm txoj kab yog txiav txim siab los ntawm qhov chaw txias muaj nyob ntawm SSHE. Cov tshuab loj sib txawv muaj xws li los ntawm cov kab qis mus rau siab muaj peev xwm. Tsis tas li ntawd ntau yam kev hloov pauv tau muaj los ntawm cov khoom siv ib leeg mus rau ntau lub raj kab, yog li cov kab ua tau yooj yim heev.

Tom qab cov khoom tau txias hauv SSHE, nws nkag mus rau hauv lub tshuab pin rotor thiab / lossis nruab nrab crystallizers nyob rau hauv uas nws yog kneaded rau ib lub sij hawm ntawm lub sij hawm thiab nrog ib tug tej yam kev siv nyob rau hauv thiaj li yuav pab txhawb kev txhawb nqa ntawm peb-dimensional network, uas. nyob rau qib macroscopic yog cov qauv yas. Yog tias cov khoom raug muab faib ua cov khoom qhwv, nws yuav nkag mus rau SSHE dua ua ntej nws nyob hauv lub raj so ua ntej qhwv. Yog tias cov khoom tau ntim rau hauv khob, tsis muaj lub raj so rau hauv cov kab crystallization.
