Nyob rau hauv cov txheej txheem txiav, peb feem ntau ntsib ntau yam teeb meem, xws li qhov tseeb ntawm kev txiav, kev ruaj ntseg ntawm lub cev ntawm cov khoom kawg, qhov smoothness ntawm lub txiav nto, qhov nyuaj ntawm kev sib cais cutter los ntawm cov khoom, thiab kev sib cais ntawm cov cutter nto thiab cov khoom siv thaum lub sij hawm sib cais tus nqi ntawm cov khoom seem hauv cov khoom siv nyuaj. Thaum cov yam ntxwv ntawm cov ntaub ntawv tsis meej, nws nyuaj rau peb kom ua tau raws li cov kev xav tau saum toj no.
Piv txwv li, rau cov ntaub ntawv uas muaj siab hardness, muaj zog brittleness, thiab muaj zog viscosity, cov tsoos txiav txoj kev yog nyuaj ua kom tiav. Raws li qhov tsis paub meej ntawm cov khoom lag luam nce ntxiv, qhov nyuaj ntawm kev txiav ua haujlwm yuav nyuaj dua. Ultrasonic txiav zaub mov yog kev ua kom zoo ntawm cov tsoos txiav. Ultrasonic zaub mov slitting tsis tsuas yog tsub kom qhov txiav ceev, tab sis kuj ua rau kev loj hlob ntawm kev txhim kho cov qauv, cov duab thiab kev ua tau zoo ntawm cov zaub mov.
Txawm hais tias rau feem ntau cov khoom, txiav cov zaub mov ultrasonic tuaj yeem txo qhov txiav quab yuam uas yuav tsum tau ua rau cov txheej txheem txiav, tab sis rau qee yam khoom, cov khoom siv kuj suav nrog. Feem ntau qhov txiav txiav yog nruab nrab ntawm 0.1-1.0. Yog tias koj kawm txog cov qauv macro thiab cov khoom siv tshuab ntawm cov khoom noj hauv cov txheej txheem txiav, xav txog cov khoom siv rau kev txiav cov zaub mov. Yog li ntawd, paub qhov txawv ntawm peb hom khoom siv hauv qab no.
1. For uniform and dense materials, such as high-fat foods, cheese, etc. These foods are characterized by a non-porous and compact structure. Hauv cov txheej txheem txiav ib txwm, ntau qhov kev sib txhuam feem ntau tsim tawm, thiab qhov loj ntawm kev sib txhuam yog cuam tshuam nrog viscosity ntawm cov khoom. Ultrasonic txiav tuaj yeem txo qhov kev sib cuam tshuam ntawm lub tshuab txiav thiab cov khoom siv thaum lub sijhawm txiav, yog li tsis txhob muaj cov yas deformation. Ntawm qhov tod tes, lub zog noj ntawm cov qauv compact thiab tsis ntxeem tau thaum lub sij hawm txiav cov txheej txheem kuj nce ho.
2. Rau cov khoom noj ntxeem tau, xws li qhob cij, ncuav mog qab zib, marshmallows thiab lwm yam khoom noj uas muaj cov qauv zoo sib xws, lawv cov yam ntxwv zoo ib yam yog ntau qhov zoo li daim txhuam cev. Tsis tas li ntawd, nws yooj yim heev rau compressed thiab deformed. Yog tias cov cuab yeej txiav tsoos siv, nws tsuas tuaj yeem ncav cuag ib feem ntawm qhov tawg. Yog hais tias nws raug txiav ntxiv, nws yuav twisted los yog tawg. Tab sis yog tias koj siv ultrasonic txiav, koj yuav ua tiav cov txiaj ntsig zoo. Vim tias ultrasonic txiav tuaj yeem txo qhov kev sib txhuam tsim tawm thaum lub sijhawm txiav, kev txiav ua haujlwm tuaj yeem ua tiav nrog lub zog txiav me me. Thaum kawg, qhov zoo nkauj thiab du nto yog tiav. Piv nrog rau kev txiav cov ntaub ntawv ntom ntom, qhov cuam tshuam ntawm kev sib txhuam ntawm cov txheej txheem txiav thaum txiav cov khoom ntxeem tau me me. Vim tias qhov chaw sib cuag tiag tiag ntawm lub tshuab txiav thiab cov khoom siv thaum lub sij hawm txiav yog tsawg dua qhov geometric cheeb tsam ntawm cov khoom. Tsis tas li ntawd, nyob rau hauv cov txheej txheem ntawm cov cuab yeej nkag mus rau hauv cov khoom, cov khoom ntxeem tau yuav tsum muaj zog ntau dua li cov khoom siv ntom ntom.
3. Cov tsiaj thiab cov ntaub so ntswg yog tag nrho cov cell-zoo li tus, muaj ntau qhov sib txawv los yog muaj pes tsawg leeg. Vim yog tsim cov zaj duab xis lubricating thiab nws cov ntsiab lus dej siab, kev sib txhuam tsis zoo tsis tseem ceeb thaum txiav. Lub rigidity ntawm cov ntaub ntawv nruj txiav txim siab txiav quab yuam. Rau feem ntau cov ntaub so ntswg, qhov yuav tsum tau txiav quab yuam yog txo los ntawm ultrasonic excitation. Tab sis rau cov qauv tawv filamentary (xws li nqaij nqaij), qee qhov teeb meem yuav tshwm sim. Qhov no yuav tsum tau frosting, pre-stressing los yog ua noj ua haus kom kho cov qauv. Nrog rau cov kev kho mob no, lub hom phiaj ntawm kev txo cov txiav tsis kam tuaj yeem ua tiav.
