Lub Tank Emulsification Hauv Margarine Ntau Lawm

Vim li cas emulsification thiaj li tsim nyog?

Margarine yog ib hom roj-hauv-dej (O/W), tab sis los ntawm kev ua tiav, nws hloov mus ua ib hom dej-hauv-roj (W/O) emulsion ruaj khov. Kev tsim thawj zaug ntawm cov khoom ua ntej-emulsion yog qhov tseem ceeb rau:

1. Kev sib kis thoob plaws:Xyuas kom meej tias cov dej me me (uas muaj ntsev, cov protein mis nyuj, cov tshuaj preservatives xws li sorbic acid, thiab cov acidulants xws li lactic acid) tau faib sib npaug thoob plaws hauv theem rog.
2. Kev Sib Koom Ua Ke:Yaj thiab faib tag nrho cov khoom xyaw me me xws li emulsifiers, xim, thiab tsw qab kom zoo.
3. Kev Ruaj Ntseg ntawm Cov Txheej Txheem:Muab cov khoom noj uas sib xws thiab sib npaug rau hauv chav txias tom qab. Kev ua kom cov khoom ua ntej tsis sib xws yuav ua rau cov khoom kawg tsis zoo, tsis ruaj khov, thiab muaj teeb meem lwj.

Cov Cheebtsam Tseem Ceeb ntawm Lub Tank Emulsification

Ib lub tank feem ntau yog lub thawv kaw, npog, ntsug ua los ntawm cov hlau tsis xeb (piv txwv li, 304 lossis 316L) rau kev huv thiab tiv taus xeb. Nws cov khoom tseem ceeb suav nrog:

1. Kev Tawm Tsam:Qhov no yog qhov tseem ceeb tshaj plaws. Feem ntau nws muaj xws li:
   • Lub Tshuab Sib Tov Khoom Ceev (Impeller):Feem ntau ib lub impeller radial-flow zoo li ib tugTurbo-Rotor-Stator sib tov khoomQhov no tsim kom muaj kev sib txhuam tshuab hnyav, rub cov kua los ntawm sab saum toj thiab yuam nws hla lub stator qhov qhib zoo, ua kom tawg cov tee dej thiab tsim cov emulsion.
   • Ib Lub Anchor los yog Paddle Stirrer:Ib lub tshuab scraper agitator uas txav mus ze rau ntawm phab ntsa ntawm lub tank. Nws txoj haujlwm yog xyuas kom meej tias txhua yam khoom hauv lub tank txav mus los, tiv thaiv cov cheeb tsam tuag thiab xyuas kom meej tias tag nrho cov khoom sib npaug. Nws tiv thaiv cov rog kom tsis txhob crystallize rau ntawm phab ntsa txias ntawm lub tank jacketed.
2. Lub tsho sov/txias:Phab ntsa ntawm lub tank muaj ob lub tsho uas muaj cov kua dej kub (feem ntau yog dej kub) ncig mus los. Qhov no yog qhov tseem ceeb rau:
   • Yaj:Ua ntej emulsification, xyuas kom meej tias tag nrho cov rog thiab cov roj yog kua kiag li.
   • Kev Tswj Kub:Khaws cov khoom sib tov kom sovsaum qhov melting point ntawm cov rog uas yaj tshaj plaws(feem ntau yog 5-10°C siab dua, feem ntau yog li ntawm 45-60°C). Qhov no tseem ceeb heev kom tiv thaiv kom tsis txhob muaj kev sib xyaw ua ke ua ntej lub sijhawm, uas yuav ua rau cov emulsion puas tsuaj.
3. Cov Khoom Xyaws Chaw Nres Tsheb:Ntau txoj kab nkag rau kev ntxiv cov theem sib txawv:
   • Cov kab tseem ceeb rau cov roj sib xyaw ua ke thiab dej / brine theem.
   • Cov chaw nres nkoj me me rau cov khoom xyaw me me xws li lecithin, tsw qab, xim, thiab cov vitamins.
4. Lub Tshuab Nqus Tsev (Xaiv tau tab sis feem ntau):Lub tank no siv tau rau hauv lub tshuab nqus tsev me me. Qhov no siv tau ob lub hom phiaj:Kev Tswj Xyuas:Cov thoob dej niaj hnub no tau koom ua ke nrog PLC/SCADA system los tswj qhov kub thiab txias, qhov ceev ntawm kev sib xyaw, cov txheej txheem ntxiv cov khoom xyaw, thiab lub sijhawm tuav.
   • Kev tshem tawm cua:Tshem tawm cov huab cua uas tau nkag los ntawm qhov sib tov, uas tiv thaiv kom tsis txhob muaj qhov ntxeem tau lossis cov qauv zoo li cov noob hauv cov margarine kawg thiab txhim kho nws qhov ceev thiab tsos.
   • Ib puag ncig tswj tau:Tiv thaiv kev oxidation ntawm cov roj rhiab heev thaum lub sijhawm ua haujlwm.

Cov Txheej Txheem Ua Haujlwm

Cov txheej txheem hauv lub tank emulsification ua raws li ib qho kev sib lawv liag tshwj xeeb:

1. Kev them nqi:Cov roj sib tov ua kua (uas muaj cov roj tawv, cov roj mos, thiab cov emulsifiers uas yaj tau hauv roj xws li mono- thiab diglycerides) raug thawb mus rau hauv lub tank ua ntej. Lub tsho cua sov qhib kom tswj tau qhov kub.
2. Kev sib xyaw:Lub tshuab nplawm anchor tau pib los tsim ib lub vortex.
3. Ntxiv:Cov theem dej (muaj dej, ntsev, tshuaj preservatives, thiab cov khoom xyaw soluble hauv dej) maj mam ntsuas mus rau hauv lub vortex ntawm cov theem roj sib hloov.Ntxiv dej rau hauv roj (tsis yog lwm yam)txhawb kev tsim cov dej-hauv-roj emulsion.
4. Kev Ua Kom Emulsification Siab:Thaum ob theem tiav lawm, lub tshuab sib tov rotor-stator uas muaj zog heev yuav raug qhib rau lub sijhawm teem tseg (piv txwv li, 5-15 feeb) los tsim cov pre-emulsion zoo.
5. Tuav:Cov khoom sib tov no raug tuav cia rau hauv qab kev sib xyaw maj mam thiab tswj qhov kub kom txog thaum nws npaj txhij rau kev pumped mus rau theem tom ntej (lub pasteurizer, yog tias siv tau, thiab tom qab ntawd lub tshuab ua kom txias).

Yuav Muaj Dab Tsi Tshwm Sim Tom Ntej?

Cov emulsion coarse los ntawm lub tank no ces pumped mus rau ib qholub tshuab hloov cua sov uas tau khawb rau saum npoo (Votator™ lossis A-unit)Ntawm no, nyob rau hauv qhov txias heev thiab kev ua haujlwm kho tshuab, cov rog crystallizesnyob ib puag ncigcov dej me me uas tawg ua tej daim me me, ua kom cov dej hauv roj emulsion ruaj khov thiab tsim cov qauv yas kawg thiab cov qauv ntawm cov margarine.

Cov Ntsiab Lus Tseem Ceeb: Cov Ntsiab Lus Tseem Ceeb

• Lub Hom Phiaj:Txhawm rau tsim kom muaj kev sib xws, ntxhib, thiab ruaj khov pre-emulsion ntawm cov rog thiab dej theem.
• Cov Txheej Txheem Tseem Ceeb: Kev tswj kubnws yog qhov tseem ceeb heev kom khaws tag nrho cov rog kom yaj.
• Lub Tshuab Tseem Ceeb: Kev co tshuab siab heevyog siv los rhuav cov dej ua ntau lab lub tee dej me me.
• Qhov Tshwm Sim:Ib qho pre-emulsion uas ruaj khov uas ua kom cov khoom margarine kawg muaj cov qauv zoo sib xws, saj, xim, thiab ruaj khov.

Hauv paus ntsiab lus, lub tank emulsification teeb tsa theem rau txhua yam uas ua raws li. Cov emulsion tsis zoo ntawm no tsis tuaj yeem kho tau tom qab thiab yuav ua rau cov khoom kawg tsis zoo.
