Cov ice cream niaj hnub no feem ntau ua tiav thiab tsim los ntawm cov cuab yeej siv tshuab, uas cov tshuab hluav taws xob tau siv los ua homogenize cov khoom xyaw, sterilize thiab lwm yam txheej txheem.Ice cream yog tsim los ntawm cov khoom siv raw khoom zoo thiab kev ua haujlwm zoo.Cov ice cream uas tsim los kuj yog mos thiab qab, nrog ib tug ntxhiab tsw.Yog li, yuav ua li cas lub Hoobkas ua dej khov siv cov tshuab hluav taws xob los ua cov khoom khov nab kuab zoo thiab saj zoo?
1. Kev ua kom tsis muaj menyuam.
Tom qab peb tau nplawm tag nrho cov khoom xyaw sib npaug, peb yuav tsum siv lub tshuab hluav taws xob kom tsis muaj menyuam.Tau kawg, peb yuav tsum tswj qhov kub ntawm lub tshuab hluav taws xob lub tshuab hluav taws xob thaum lub sijhawm ua kom tsis muaj menyuam.Yog tias qhov kub thiab txias heev, nws yuav cuam tshuam rau qhov zoo ntawm cov ice cream.Saj, yog tias qhov kub thiab txias tsis dhau, kev ua kom tsis muaj menyuam yuav tsis meej, yog li yuav ua li cas tua cov kab mob tsis muaj kev cuam tshuam rau saj ntawm ice cream?
Qhov tseeb, lub Hoobkas dej khov siv lub tshuab hluav taws xob ua kom tsis muaj menyuam, uas yog pasteurized.Lub Hoobkas dej khov yuav siv lub tshuab hluav taws xob ua kom tsis muaj menyuam ntawm qhov kub thiab txias.Nws kav ntev li ib nrab teev kom tua cov kab mob thiab kab mob., pwm, thiab lwm yam raug tua tag nrho, uas tuaj yeem ua kom ntseeg tau tias kev tu cev thiab kev huv ntawm cov ice cream ncav cuag tus qauv.
Vim li cas thiaj siv lub tshuab hluav taws xob ua kom tsis muaj menyuam?Cov txiaj ntsig yog dab tsi?Qhov tseeb, lub Hoobkas dej khov tuaj yeem txo cov khoom noj khoom haus tsis zoo ntawm cov dej khov nab kuab thaum siv lub tshuab hluav taws xob rau pasteurization, yog li ua kom cov khoom noj khoom haus tsis zoo.Thiab cov chav uas tsim los ntawm lub tshuab hluav taws xob yog huv heev, ntsuab thiab tsis muaj kuab paug, thiab yuav tsis tsim cov khoom seem thaum lub sij hawm tsim khoom, uas yog tshwj xeeb yog ib puag ncig tus phooj ywg thiab noj qab nyob zoo.
2. Homogenization kev kho mob.
Txoj kev pasteurization kuj yuav tsum tau homogenize cov ntaub ntawv raw, thiab qhov kub thiab txias yuav tsum tau tswj thaum homogenization.Yog tias qhov ntsuas kub tsawg dhau, qhov viscosity ntawm cov hnoos qeev yuav nce, uas ua rau muaj teeb meem nrog cov nyhuv homogenization.Yog tias qhov kub thiab txias dhau lawm, cov rog yuav tshwm sim, thiab cov rog yuav txo tau.
Lub tshuab hluav taws xob yog siv rau hauv cov txheej txheem dej khov homogenization, feem ntau vim tias lub tshuab hluav taws xob muaj peev xwm tswj tau qhov kub thiab txias hauv qhov cuam tshuam, thiab tuaj yeem tsim qhov kub thiab txias tsis tu ncua, thiab cov khoom siv khov ua kom homogeneous muaj qhov zoo nkauj, Lubrication, ruaj khov. thiab cov duab ntev ntev, tuaj yeem txhim kho qhov nthuav dav, txo cov dej khov crystallization, thiab lwm yam, thiab thaum cov dej khov sib tov sib xyaw, nws tuaj yeem ua kom zoo dua qub nrog lub tshuab hluav taws xob.
Tau kawg, qhov kub thiab txias yog qhov tseem ceeb heev hauv cov txheej txheem homogenization, tab sis muaj lwm qhov tseem ceeb uas tseem ceeb heev, uas yog, siab.Nyob rau hauv cov txheej txheem homogenization, lub siab vapor siab yuav tsum tau tswj nyob rau hauv ib tug tej yam ntau yam, thiab lub siab yuav tsum tsis txhob qis heev los yog siab dhau.Lub tshuab hluav taws xob lub tshuab hluav taws xob kuj tseem yog lub tshuab hluav taws xob siab, thiab nws yuav tsim kom muaj qee qhov siab thaum cua sov, yog li thaum siv lub tshuab hluav taws xob kom nce qhov kub, nws yog qhov tsim nyog los kho lub siab rau lub siab xav tau rau homogeneity, thiab nce qhov kub thiab txias. thiab pressurize, kom cov nyhuv homogenization yuav zoo dua.
