Cov dev muaj lub plab zom mov tshwj xeeb nrog lub plab acid siab ntau thiab cov hnyuv luv, txhais tau tias cov zaub mov nyob hauv lawv lub cev tsuas yog 8-12 teev, xav tau kev zom zaub mov zoo. Extruded aub zaub mov tau ua tiav los ua cov khoom xyaw yooj yim rau cov dev zom thiab nqus, thaum txo kev ua xua rau plab hnyuv mucosa, muab kev saib xyuas rau lawv txoj kev noj qab haus huv.

Ua ntej, cov txheej txheem extrusion ua rau dev cov khoom xyaw yooj yim rau zom thiab zom. Raws li tau hais ua ntej, qhov kub thiab txias ib puag ncig siab gelatinizes cov hmoov txhuv nplej siab hauv cov khoom xyaw. Gelatinized starch molecules muaj cov qauv xoob, tso cai rau amylase hauv tus dev txoj hnyuv kom sai sai rau lawv, ua kom cov txheej txheem tawg. Rau cov khoom xyaw protein, qhov kub siab denatures cov proteins, cuam tshuam lawv cov qauv spatial, ua rau nws yooj yim dua rau digestive enzymes nkag mus rau cov protein ntau qhov chaw, yog li ua rau cov protein ntau digestibility thiab nqus tau. Cov kev sim qhia tau hais tias cov khoom noj dev extruded muaj protein ntau dua 85%, thaum cov zaub mov qhuav dog dig tsuas muaj cov protein digestibility ntawm ib ncig ntawm 70%. Qhov kev zom zaub mov siab no txhais tau hais tias cov zaub mov nyob hauv tus dev cov hnyuv rau lub sijhawm luv, txo qhov kev khaus ntawm cov zaub mov seem thiab txo qis kev pheej hmoo ntawm plab hnyuv thiab cem quav.

Thib ob, cov txheej txheem extrusion tshem tawm cov khoom ua kom khaus los ntawm cov khoom siv raw, tiv thaiv lub plab hnyuv mucosa. Ntau cov khoom xyaw ntuj muaj cov tshuaj uas ua rau tus dev lub plab zom mov, xws li trypsin inhibitors hauv cov taum pauv thiab ntxhib fiber ntau hauv cov nroj tsuag - cov khoom xyaw. Qhov kub thiab txias thaum lub sij hawm extrusion zoo rhuav tshem cov irritants, nrog ib tug trypsin inhibitor tshem tawm tus nqi ntawm ntau tshaj 98%. Coarse fiber impurities kuj yog hauv av rau hauv cov fibers zoo, uas tsis tsuas yog tsis ua rau lub plab zom mov, tab sis kuj txhawb txoj hnyuv peristalsis thiab pab zom zaub mov. Rau cov dev uas muaj lub plab rhiab los yog enteritis, cov khoom zoo ntawm cov khoom noj dev extruded txo kev sib txhuam thiab kev ua xua rau lub plab hnyuv mucosa, tiv thaiv kev mob los yog ua rau mob hnyav.

Cov qauv pellet ntawm cov khoom noj dev extruded kuj muaj txiaj ntsig zoo rau kev noj qab haus huv ntawm plab hnyuv. Cov qauv microporous nyob rau saum npoo ntawm cov pellets tso cai rau cov qaub ncaug thiab cov kua txiv digestive kom nkag mus rau hauv cov pellet sai sai, ua kom cov dej ntub thiab tawg ntawm cov zaub mov thiab txo kev puas tsuaj rau cov hlab pas thiab lub plab phab ntsa los ntawm nqos cov zaub mov qhuav. Ib txhij, lub pellet hardness thiab loj yog precisely tswj kom haum tus dev lub peev xwm zom. Cov khoom noj uas zom tau zoo sib xyaw nrog cov qaub ncaug, pib ua cov txheej txheem digestive thiab txo cov plab zom mov ntawm lub plab. Rau cov dev laus lossis cov dev uas muaj cov hniav uas ploj lawm, extruded mos mos cov khoom noj yuav tsum tau zom tsawg dua, ua kom nws nqos tau yooj yim thiab zom, yog li zam kom tsis txhob muaj cov khoom noj tsawg thiab cov teeb meem hauv plab hnyuv los ntawm kev zom zaub mov.
