Kev cuam tshuam ntawm cov khoom siv raw
Ua ntej nkag mus rau hauv lub extruder, tshem tawm impurities hauv cov khoom los tiv thaiv pob zeb thiab av nkos los ntawm kev hnav thiab rhuav tshem lub extruder lub kauv conveyor thiab ntsia hlau, thiab tib lub sijhawm txhim kho cov khoom zoo. Thaum cov dej noo nyob rau hauv cov khoom siv raw yog siab dhau, nws yooj yim rau choke lub tshuab thaum pub mis. Cov dej noo tsis tuaj yeem tawm hauv lub sijhawm luv luv, thiab nws tsis tuaj yeem extruded. Nws ua mos thiab tsis crispy. Cov ntsiab lus siab noo noo shortens lub txee lub neej ntawm cov khoom noj dev. Thaum cov ntsiab lus noo noo tsawg dhau, nws tseem yuav txo qis extrusion degree ntawm cov khoom noj dev, noj ntau lub zog, thiab cuam tshuam rau cov zis.

Kev pub mis tsis sib npaug
Yuav kom tswj tau qhov zoo ntawm cov khoom extruded thiab kev ua haujlwm tsis tu ncua ntawm extruder, kev pub mis yuav tsum muaj peev xwm ua tau raws li qhov xav tau ntawm extruder. Kev pub mis tsis txaus yuav ua rau tsis txaus siab extrusion nyhuv. Kev pub mis ntau dhau yuav yooj yim thaiv lub tshuab thiab txo qis ntau lawm.
Tempering kub
Lub puffing ntawm cov zaub mov dev tuaj yeem muab faib ua cov txheej txheem qhuav thiab txheej txheem ntub. Cov txheej txheem ntub dej zoo heev txhim kho cov txiaj ntsig thiab palatability ntawm cov khoom noj dev los ntawm kev siv tshuab tempering, thiab tseem siv thiab xaiv. Tempering thev naus laus zis yog qhov txuas tseem ceeb heev hauv kev tsim cov khoom noj dev, yog li yog tias cov tshuab tempering tau zoo, qhov zoo thiab cov txiaj ntsig ntawm cov khoom noj dev yuav ntau dua. Raws li kev tshawb fawb, ob tus neeg laus dev thiab menyuam dev muaj qhov nyiam rau dev noj zaub mov nrog qhov kub thiab txias ntawm 96 degree, yog li qhov kub thiab txias ntawm cov pa ntxiv ncaj qha cuam tshuam rau qib puffing thiab hardness ntawm cov zaub mov dev. Yog tias qhov kub thiab txias dhau los yog qis dhau, lub zog extrusion ntawm extruder tsis txaus, thiab cov hmoov txhuv nplej siab gelatinization degree hauv cov ntaub ntawv raw tsis txaus, uas cuam tshuam ncaj qha rau palatability ntawm cov khoom noj dev.
