Cov txheej txheem ntawm kev txo cov roj nqus tus nqi ntawm fryer

1. Tswj cov concentration ntawm surfactant nyob rau hauv cov roj kib ntawm fryer
Cov xwm txheej rau cov khoom noj kib nrog cov roj tsawg tuav tus nqi thiab cov khoom zoo yog raws li hauv qab no:
A. Cov ntsiab lus ntawm cov polar nto active Cheebtsam (phospholipids, saponifiers, monoglycerides, diglycerides, polar polymers, thiab lwm yam) nyob rau hauv kib roj yog 15 feem pua ​​- 25 feem pua ​​(cov ntsiab lus ntawm polymers yuav tsum tau tswj ntawm 5 feem pua ​​{{3. }} feem pua ​​, thiab cov ntsiab lus ntawm alkaline saponifiers yuav tsum yog 35 - 75 mg).
B. Cov ntsiab lus ntawm cov roj nruab nrab (triglyceride) yog 75 feem pua ​​- 85 feem pua ​​. Yuav kom ua tau raws li qhov yuav tsum tau ua, cov roj tshiab yuav tsum tau muab ntxiv tas li thaum lub sij hawm kib (cov roj hauv lub lauj kaub yuav tsum tau rov ua dua txhua 10 teev), thiab cov khoom noj uas tsis muaj kuab lom thiab cov dej soluble saum npoo av hauv cov roj kib yuav tsum raug tshem tawm los ntawm kev lim roj. Cov khoom siv lim roj tuaj yeem yog silica gel, alum, cellulose thiab activated carbon.
2. Tswj qhov kub ntawm lub fryer thiab cov ntsiab lus dej ntawm cov khoom noj
Thaum cov zaub mov kib ntawm cov roj kub ntawm 150 - 190 degrees, cov roj tuav tus nqi yog linearly thiab zoo correlated nrog lub hauv paus square ntawm lub sij hawm kib.
Kev paub dhau los tau ua pov thawj tias txawm tias qhov ntsuas kub npaum li cas ntawm cov khoom noj uas muaj dej ntau yog kib, nws cov roj tuav tau ntau dua li cov ntsiab lus dej tsawg. "High pressure frying" muaj txiaj ntsig zoo rau cov khoom noj muaj dej noo vim tias nws tuaj yeem ua rau cov roj kub thiab ua kom lub sij hawm luv luv, txo cov dej poob thiab roj nqus, thiab ua rau cov khoom muaj kua thiab mos. Txawm li cas los xij, txoj kev no yuav tsum tsis txhob siv rau sizing (hmoov), vim tias nws saj tsis yog nkig li "ib txwm siab frying". Cov khoom noj no yuav tsum yog "nqus kib" txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhuam nws nws nws yuav tsum tau ua cov khoom lag luam nrog cov roj tsawg thiab nkig saj.
3. Tswj lub cev thiab tshuaj lom neeg ntawm cov zaub mov
A. Kho cov qauv zaub mov
Ntau cov khoom noj kib yog tsim los ntawm ntau yam khoom xyaw. Ntawm cov khoom xyaw no, ntxiv cov hmoov nplej hmoov nplej tuaj yeem tsis tsuas yog ua kom muaj txiaj ntsig zoo ntawm cov zaub mov, tab sis kuj txo cov roj nqus cov nqi; Tsis tas li ntawd, qhov sib ntxiv ntawm cov hmoov cellulose thiab carboxymethyl cellulose muaj cov nyhuv tib yam. Nws kuj yog ib qho zoo rau kev nce cov neeg noj cov fiber ntau, uas tuaj yeem hais tias tua ob tus noog nrog ib lub pob zeb.
B. Kev kho deg
Ntev npaum li qhov saum npoo ntawm cov khoom noj kib yog tiaj thiab du, cov roj nqus dej yuav qis dua li cov uas muaj qhov ntxhib thiab tsis sib xws, yog li qhov kev txiav yuav tsum du thiab tiaj tus. Cov zaub mov saum npoo yog coated nrog muab tshuaj txhuam thiab tom qab ntawd kib, uas tuaj yeem txo cov evaporation ntawm cov dej, txo cov roj nqus tus nqi thiab tau txais kev saj zoo.
C. Tswj qhov "surface area/quality" value of food
Qhov "surface area/mass" tus nqi ntawm cov zaub mov yog zoo correlated nrog cov roj nqus tus nqi. Ntawm qhov chaw tsis cuam tshuam rau cov khoom zoo, thaj chaw ntawm cov zaub mov yuav tsum yog me me es tsis yog loj, uas yog, qhov ntau dua qhov tuab ntawm cov khoom, qhov qis dua cov roj nqus.
D. Tswj cov kev sib tshuam ntawm cov khoom noj thiab roj kib
Nyob rau hauv kev tsim khoom, kev siv roj txuas ntxiv siv thev naus laus zis tuaj yeem siv los tswj kom muaj qhov sib npaug ntawm cov dej sib txuas ntawm cov khoom siv hauv cov roj kib thaum lub sij hawm kib, kom tswj cov roj nqus cov khoom noj kom zoo.
Txhawm rau kom ntseeg tau tias cov khoom noj kib kib los ntawm lub fryer khaws nws cov khoom qub, cov neeg yuav txo cov roj nqus ntawm txhua yam. Kev txo qis ntawm cov roj nqus dej tuaj yeem tsis tsuas yog ua kom cov khoom noj khoom haus zoo xwb, tab sis kuj txuas ntxiv lub neej kev pab cuam ntawm cov khoom thiab txo cov roj noj.
