Extruders yog ntau yam thiab siv dav hauv kev pub, khoom noj, thiab kev lag luam. Raws li cov extruders (qhuav, ntub dej, ib leeg- ntsia hlau, los yog ntxaib- ntsia hlau), peb qhia ib los yog ntau lub zog hauv cov txheej txheem extrusion:
agglomeration: Thaum lub sij hawm extrusion, cov khoom noj los yog cov khoom xyaw pub khi ua ke thiab sib sau ua ke rau hauv cov khoom me me.
Degassing: Cov npuas hauv cov zaub mov lossis cov khoom xyaw pub yog muab tshem tawm thaum lub sij hawm extrusion.
Lub cev qhuav dej: Hauv cov khoom noj lossis cov txheej txheem pub extrusion, cov ntsiab lus noo noo yog txo los ntawm 4% -7%.
Kev nthuav dav: Cov kev ua haujlwm thiab kev teeb tsa ntawm lub extruder tuaj yeem tswj tau qhov ntom ntom (piv txwv li, dab dej lossis ntab) ntawm cov zaub mov tsiaj thiab dej pub.
Gellination: Extrusion ua noj tuaj yeem gelatinize hmoov txhuv nplej siab (los ntawm ntau qhov chaw, xws li tubers lossis nplej) thaum ua zaub mov lossis tsiaj ua zaub mov.
Kev Sib Tsoo: Cov ntaub ntawv nyoos tuaj yeem ua rau hauv av rau qee qhov ntawm cov extruder thaum lub sijhawm ua zaub mov lossis khoom noj.
Homogenization: Cov txheej txheem homogenization ntawm ib qho extruder hloov cov qauv ntawm cov ntaub ntawv tsis zoo, hloov lawv mus rau hauv daim ntawv ntau dua.
Kev sib xyaw: Thaum lub sij hawm extrusion txheej txheem, ntau yam extruders muab ntau yam ntawm cov ntsia hlau los tsim cov kev sib xyaw sib xyaw.
Pasteurization thiab Sterilization: Nyob rau hauv cov khoom noj los yog pub extrusion txheej txheem, raw khoom yuav pasteurized los yog sterilized siv extrusion technology.
