Txau Tshuab Cov Roj Thiab Roj Roj Tshuab

Txau cov tshuab nqus dej yog siv los ua cov roj thiab cov rog. Lawv lub hom phiaj tseem ceeb yog hloov cov roj ua kua thiab cov rog (lossis emulsions muaj cov roj thiab cov rog) rau hauv dawb-} khiav hmoov. Qhov no daws ntau qhov tsis yooj yim nyob rau hauv chav khaws cia, kev thauj mus los thiab siv cov roj ua kua thiab cov rog, thiab coj cov kev ua haujlwm zoo.

Tus tseem ceeb thiab kev ua tau zoo thiab cov txiaj ntsig ntawm kev hloov roj thiab cov rog ua hmoov muaj xws li:

Txhim kho ruaj khov thiab txuas ntxiv rau lub neej

• Lub cev ruaj khov: Cov hmoov hauv lub xeev tshem tawm cov stratification thiab nag lossis daus teeb meem uas yuav muaj nyob hauv cov roj ua kua.
• Oxidative Stability: Qhov no yog ib qho tseem ceeb tshaj plaws. Cov roj ua kua thiab cov rog yog qhov ua tau rau oxidation thiab rancidity thaum raug rau huab cua (oxygen), lub teeb thiab kub. Txau cov txheej txheem:

1. Cov roj ntsha: cov roj thiab cov rog tau encapsulated hauv cov khoom siv phab ntsa (xws li cov roj ntsha uas tau hloov kho lub cev, ua kom muaj cov pa roj ntsha, cov roj ntsha li ntawm cov pa roj Oxygen, kev sib tw thiab cov roj ntsha ({

2. Txo cov dej num dej: Tus txheej txheem ziab tau txo cov dej ua haujlwm ntawm cov khoom lag luam, inhiberming microbial kev loj hlob thiab qee qhov oxidation kev tawm tsam.

3. Antioxidants tuaj yeem ntxiv: antioxidants (xws li TBHQ, BHT, Toculsification Theem rau cov hmoov pob ntseg tau faib rau hauv cov hmoov, ntxiv ncua oxidation.

Txhim kho cov fluidity thiab yooj yim ntawm kev siv

• Hmoov noj muaj cov fluidity zoo heev thiab yooj yim kom muaj tseeb los ntawm cov khoom metering thiab cov khoom siv sib xyaw, txhim kho ntau qhov ua tau zoo thiab cov khoom siv cov mis.
• Nws zam cov teeb meem ntawm cov roj ua kua roj ua qhov hnyav, thiab nyuaj rau cov khoom kom qhuav (xws li hmoov nplej qhuav (mis nyuj hmoov, thiab hmoov nplej hmoov).

Yooj yim cia thiab tsheb thauj mus los

• Cov hmoov muaj zog me me hauv ntim thiab siab dua nyob rau hauv ntom ntom nti ntau dua li kua, uas zoo heev txuag cia thiab tsheb thauj mus los thiab txo cov nqi logistics.
• Daim foos hmoov yog tsawg dua qub to to zau, thiab ntim thiab tsheb thauj mus kom muaj kev nyab xeeb dua thiab huv.

Nthuav cov kev hloov ntawm daim ntawv thov

• Hmoov noj ua tau yooj yim ntxiv rau ntau yam khoom noj uas tseev kom muaj rog tab sis xav tau cov hmoov av qhuav, xws li:

1. Dej qab zib (Kas fes, Creamer Hmoov, Cocoa Hmoov)

2. Ci Premix (ncuav mog qab zib hmoov, mov nplej)

3. Kua zaub hmoov, kua ntses

4. Cov hmoov kav dej khov, cov mis hmoov

5. Cov Khoom Noj Khoom Haus, Kev Noj Mov Noj Hloov

6. Khoom qab zib, Chocolate khoom

7. Nqaij ua (raws li kev ua rog hmoov)

• Hmoov cov rog cov khoom lag luam nrog cov khoom muaj nuj nqi tshwj xeeb (xws li cov ntsiab lus melting sib txawv, txawv emulsification) tuaj yeem tsim tau.

Txhim kho dispersibility thiab solubility

Tom qab tsuag tshuaj tsuag, thaum cov hmoov ntawm cov roj emulsamified yog cov rog tuaj yeem ua rau muaj cov khoom ruaj khov thiab tusyees ua rau cov khoom ruaj khov, uas yog qhov tseem ceeb rau cov khoom lag luam uas tseem ceeb.

Cov txheej txheem ntawm kev hloov ua cov roj ua kua rau hauv cov roj yog ib txwm muajTxheej Txheem Microencapsulation, thiab cov kauj ruam tseem ceeb yog li hauv qab no:

Cov Qauv Tsim thiab Khoom Siv Raw Khoom

• Roj: Xaiv cov roj uas yuav tsum tau hmoov (xws li cov roj xibtes, roj pleev roj, roj mis, roj noj, thiab roj.
• Cov Khoom Siv Phab Ntsa: Xaiv ib lub phab ntsa tsim nyog rau encapsulate cov roj. Cov ntaub ntawv phab ntsa muaj xws li:

1. Carbohydrates: Hloov cov hmoov txhuv nplej siab (xws li Sodium Wasch Octen succinate), maltodextrin, pob kws pob kws syrodextrin, cyclodextrin, cov kab mob gob.

2. Cov protein: Whey Protein, sodium sib cais, soy protein cais tawm.

3. Colloids: guar pos hniav, xanthan ntawm cov pos hniav.

4. Feem ntau ntau cov ntaub ntawv phab ntsa yog siv los ua tiav emulsification zoo tshaj, zaj duab xis - Txoj kev ua, embedding tus nqi thiab solubility.

• Emulsifier: ntxiv emulsfiers (li Monoglyin, lecithin, soob esters, thiab lwm yam) los pab ua daim ntawv me thiab ntau dua cov roj me me.
• Antioxidants: ntxiv raws li xav tau.
• Dej: Raws li kev rho tawm nruab nrab.

Emulsification

• Ua kom sov cov roj mus rau saum toj lub ntsej muag melting (khaws nws hauv cov kua).
• Dissolve lossis tawg cov khoom siv phab ntsa, emulsifier, antioxidant, thiab lwm yam hauv dej kub kom ua rau theem dej.
• Maj mam ntxiv cov roj kub rau hauv dej hauv qab high - ceev shear stirring los ua ib coarse emulsion.
• Qhov no yog qhov tseem ceeb tshaj plaws, lub hom phiaj yog kom tau cov roj roj ntau tshaj plaws thiab tawg ntawm tusyees.

Homogenization

• Lub coarse emulsion yog homogenized los ntawm high {{0} h siab homogenizer (feem ntau 1-2 zaug ntawm 10-50 MPa lossis siab dua siab).
• High -} high homogenization homogenization txuas rau hauv micron lossis txawm tias muaj cov dej khov kho tshiab, feem ntau yog lub cev muaj dej {}} hauv roj emulsion. Cov roj nplua roj yog tus yuam sij kom tau txais cov hmoov loj ua kom zoo.

Txau Kom Qhuav

• Tso cov homogen tseem ruaj khov Emulsion rau hauv atomizer rau saum toj ntawm cov tsuag kom qhuav ntauwd.
• Atomization: lub emulsion yog atomized rau hauv cov tee dej zoo heev (kaum mus rau ntau pua ntawm microns). Feem ntau yog siv atomizers yog:

1. Qeeb Atomizer: siab {- Ceev rotating disk rau cov kua ua kom zoo.

2. Siab Nozzle: Kev siab siab yuam cov kua kom ua kom mist los ntawm lub qhov me me.

3. Airflow nozzle: Siv siab siab- Ceev maj mathflow los rhuav rau cov kua rau mob.

• Kom qhuav: huab cua kub (feem ntau ntawm 160-220℃ntawm qhov inlet kub, nyob ntawm cov khoom siv kub heev, nyob ntawm qhov chaw qhuav lossis cov chaw ntawm cov dej ntws zoo ib yam. Cov dej nyob hauv cov dej ntws yog evaporated nyob rau hauv lub sij hawm luv luv (ob peb feeb mus rau kaum ntawm vib nas this).
• Cov hmoov txheej txheem: Tom qab cov dej yaj ua kom sai, cov khoom siv phab ntsa nrawm nrawm nrawm, uas qhwv cov roj sab hauv los ua cov microcapsule qhuav (hmoov roj).
• Txias thiab sau khoom: Cov hmoov nplej qhuav ntog rau hauv qab ntawm cov pej thuam thiab sib cais thiab sau los ntawm cov pa roj cua los ntawm kev sib cais los ntawm cov lim dej. Cov hmoov uas tau sau tseem nyob ntawm qhov kub thiab txias thiab xav tau txias sai sai (xws li lub txaj ci txias) los tiv thaiv agglomeration thiab thermal puas.

Tshaj tawm - kev thiab ntim

• Kev Ntsuam Xyuas: Kev Ntsuam Xyuas lossis agglomerated hais yuav raug tshem tawm los ntawm cov ntxaij vibrating kom ntseeg tau tias hmoov hmoov.
• Anti - Caking Kev Kho Mob: Qee zaum ib qho me me ntawm anti-
• Ntim: hauv qhov chaw noo ib puag ncig (tswj kev nqus dej noo thiab khaws cia rau hauv cov ntaub ntawv noo (xws li cov hnab ntim khoom sib xyaw (xws li Aluminium NTAWV CO hnab).

• Emulsion stability: qhov ruaj khov ntawm emulsion ua ntej homogenization ncaj qha cuam tshuam cov khoom zoo thiab kos duab ntawm cov hmoov kawg.
• Cov nyhogenization nyhuv: qhov loj me thiab faib cov roj mob yog cov tseem ceeb uas txiav txim siab qhov teeb tsa ua haujlwm.
• Cov ntsiab lus ruaj khov: Cov ntsiab lus ruaj khov ntawm cov emulsion (tag nrho cov khoom siv hluav taws xob yooj yim, ziab cov khoom ntawm cov hmoov (ntom, hauv qab). Nws feem ntau yog optimized ntawm 30% -50%.
• Inlet huab cua kub thiab offlet huab cua kub: inlet pa taws kub cuam tshuam thiab ua hauj lwm zoo; Qhov hluav taws xob huab cua kub yog qhov taw qhia tseem ceeb rau kev tswj hwm cov ntsiab lus noo noo, uas yuav tsum muaj kev sib npaug ntawm cov cua sov {}}}, cov protein). Qhov hluav taws xob huab cua sov yog tswj tau ntawm ib ncig 80-100 degree.
• Cov nyhuv atomization: lub droplet loj cuam tshuam rau cov kev ziab khaub ncaws thiab qhov loj me thiab cov yam ntxwv ntawm cov hmoov kawg.

Txau kom qhuav yog lub thev naus laus zis rau kev tsim cov roj hmoov. Los ntawm kev ua tib zoo tsim cov mis (cov roj, cov khoom siv phab ntsa, tso kua dej khov kho kom hloov mus rau hauv qhov ruaj khov, zoo {}}} ntws, Yooj yim - rau -}}- lub neej thiab dav siv hmoov hmoov. Lub hom phiaj tseem ceeb ntawm tag nrho cov txheej txheem yog kom ua tiav cov roj microencapsulation ntawm cov roj kom ua tiav lub hom phiaj ntawm kev tiv thaiv thiab kev ua haujlwm.
