Pub puffing tshuab ua ntej-gelatinized starch ntau lawm txheej txheem

Pre-adjusted noo noo cov ntsiab lus ntawm 15-20% ntawm cov hmoov nplej ntub dej rau hauv lub tshuab extrusion, hmoov txhuv nplej siab los ntawm cov kauv ncej txhuam extrusion kub thiab muab tshuaj txhuam, thiab tom qab ntawd los ntawm qhov aperture ntawm 1-10 hli qhov siab-siab extrusion, Kev nkag mus rau hauv huab cua ntawm cov khoom yuav yog instantaneous expansion thiab ziab, crushed, tshuaj ntsuam uas yog, pre-gelatinized starch.

Vim lub siab siv ntawm shear, lub viscosity ntawm cov khoom txo qis, thiab solubility ntawm cov khoom yog ntau dua li cov txheej txheem ntawm cov menyuam. Raws li nyob rau hauv cov txheej txheem tsim khoom yeej tsis tas yuav tsum tau ntxiv dej, tuaj yeem siv qhov sib txhuam sab hauv los tswj qhov kub ntawm 120 - 160 degree, ziab tsis xav tau qhov cua sov. Cov txheej txheem no yog tus cwj pwm los ntawm kev nqis peev tsawg hauv cov khoom siv, kev siv hluav taws xob tsawg, viscosity los ntawm kev siv tshuab ntau lawm nrog rau cov qauv siv tau los ua kom tau raws li qhov yuav tsum tau ua thiab txo cov nqi tsim khoom.
