Qhov zoo ntawm Extrusion Tsiaj Khoom Noj Ntses Pub

(1) Tshem tawm cov tshuaj tiv thaiv kev noj zaub mov zoo thiab txhim kho kev zom zaub mov thiab kev nqus ntawm cov khoom noj. Muaj ntau yam tshuaj tiv thaiv kev noj qab haus huv hauv cov khoom noj, xws li saponins, gossypol, trypsin inhibitors, thiab lwm yam hauv rapeseed noob, soybean ncuav mog qab zib thiab paj noob hlis ncuav mog qab zib. Nyob rau hauv qee qhov dej thiab qhov kub thiab txias, cov tshuaj tiv thaiv kev noj zaub mov no Hauv cov txheej txheem ntawm puffing, ib feem ntawm cov kev ua ub no maj mam ploj, yog li txo qhov kev puas tsuaj rau lub cev endogenous digestive enzymes ntawm tus tsiaj lub cev, txhim kho kev zom thiab nqus ntawm cov khoom noj, thiab txo excretion. tus
(2) Kub-kub tshuaj tua kab mob kom ntseeg tau tias muaj kev nyab xeeb thiab huv si ntawm cov khoom noj. Qhov siab tshaj plaws ntawm extrusion tuaj yeem ncav cuag li 150 degree, thiab lub sijhawm ua haujlwm ntawm cov khoom noj khoom haus ntawm qhov kub thiab txias yog luv heev, txog 8 vib nas this. Tom qab cov khoom siv raw yog extruded nyob rau hauv qhov kub thiab txias siab, ntau yam kab mob, kab qe thiab kab mob pathogenic nyob rau hauv cov khoom noj yuav raug tua, qhov zoo ntawm cov khoom noj tuaj yeem txhim kho, thiab cov kab mob plab hnyuv ntawm cov tsiaj tuaj yeem txo.
(3) Txhim kho lub palatability thiab tsw ntawm cov khoom. Cov khoom puffed muaj xoob, ntxeem tau, nkig qauv, zoo palatability thiab tsw. Cov qauv tuaj yeem ua rau cov duab sib txawv ntawm qhov tuag, yog li cov duab sib txawv ntawm extruded pellets uas tsiaj nyiam tuaj yeem nias. Nws tseem tuaj yeem tsim cov khoom noj muaj roj tshwj xeeb, xws li Atlantic salmon, zaj sawv trout thiab lwm hom kab lis kev cai, cov khoom noj muaj roj ntxiv yog siab heev, qee qhov siab li 30 feem pua.
(4) Txhim kho gelatinization degree ntawm cov hmoov txhuv nplej siab, uas muaj txiaj ntsig zoo rau kev zom thiab nqus cov hmoov txhuv nplej siab. Cov kev tshawb fawb tau pom tias qib ntawm gelatinization ntawm cov hmoov txhuv nplej siab hauv cov khoom noj tuaj yeem nce ntawm 13 mus rau 13 tom qab extrusion. 58 feem pua ​​​​nce mus rau 81.55 feem pua ​​​​, qhov siab dua ntawm puffing, qhov yooj yim dua nws yog siv los ntawm cov enzymes. Zaub raw cov ntaub ntawv tau ua tiav nyob rau hauv qhov kub thiab txias siab thaum lub sij hawm puffing txheej txheem los ua cov hmoov txhuv nplej siab gelatinization thiab protein lub koom haum, uas muaj txiaj ntsig zoo rau tsiaj zom thiab nqus, thiab txhim kho kev zom zaub mov thiab kev siv ntawm cov khoom siv raw. Kev zom cov khoom hauv dej tuaj yeem nce ntxiv los ntawm 10% ~ 35% tom qab puffing.

(5) Txhim kho kev zom zaub mov thiab kev nqus ntawm cov khoom siv lo lus. Lub plab zom mov ntawm cov ntses yog luv luv, thiab feem ntau ntawm lawv yog cov ntses tsis plab, yog li cov zaub mov zoo dua, qhov kev zom zaub mov ntau dua thiab nqus tau. Cov txheej txheem extruding yuav tsum tau finer crushing ntawm raw cov ntaub ntawv, yog li txhim kho lub plab zom mov thiab nqus cov ntses. Tam sim no, crushing fineness ntawm raw khoom rau high-qib extruded dej cov khoom xws li seawater ntses nyob rau hauv Tuam Tshoj tau mus txog 95 feem pua ​​​​ntawm 80 mesh, thaum lub crushing fineness ntawm raw cov ntaub ntawv rau extruded raw cov ntaub ntawv ntawm ntau hom xws li nyom carp, tilapia. thiab pomfret kuj tau mus txog 95 feem pua ​​​​60 mesh. tus
(6) Cov khoom siv puffed yog qhov zoo rau kev khaws cia thiab tswj kev yug me nyuam. Vim yog qhov kub thiab txias siab puffing thiab ziab qhuav, cov dej noo ntawm cov khoom tiav feem ntau yuav tsum tsawg dua 10.0 feem pua ​​. Lub ntim feem ntau siv txoj kev sib khi lub hnab sab hauv thiab sab nraud cais, yog li nyob rau hauv tib lub sijhawm, lub txee lub neej ntev dua thiab nws yooj yim rau khaws cia.
(7) Lub extruded pub muaj dej ruaj khov, tsis tawg hauv 16 mus rau 32 teev, thiab muaj kuab paug me me rau cov dej tsis zoo. Cov khoom xoob thiab ntxeem tau extruded ntab ntab ntab rau saum npoo dej, uas yooj yim rau kev saib xyuas kev noj zaub mov thiab kev loj hlob ntawm cov ntses, uas muaj txiaj ntsig zoo rau kev tswj hwm kev tshawb fawb; Thaum cov roj ntau thiab ntom nti extruded submerged cov khoom muaj qhov ruaj khov nyob rau hauv dej ntau dua 16 teev, ua kom muaj ntses pub kom txaus thiab txo cov pov tseg.
