Vim li cas cov pub Extruder yog li dav siv?

Lub pellet pub tsim tawm los ntawm cov khoom noj exudder ntev lub txee lub neej ntawm extruded pub, ua rau nws tau yooj yim rau khw thiab thauj nws dhau mus deb. Extruded pub tsis yog yooj yim rau khaws cia, tab sis kuj muaj qhov tseem ceeb hauv kev pub mis thiab kev tswj hwm. Nyob rau hauv aquaculture, extruded pub tuaj yeem faib ua peb hom: qeeb supling thiab nrawm nrawm nrawm, nyob ntawm cov txheej txheem kev pub khoom noj ntawm ntau hom khoom lag luam. Txoj kev kawm pub mis no tsis tsuas yog txuag tau ntau lub sijhawm, tab sis kuj txhim kho kev ua haujlwm tsim khoom.

Txawm hais tias extruded pub muaj ntau yam zoo hauv kev pub mis thiab kev tswj hwm, tseem muaj qee yam shortcomings. Piv txwv li, thaum lub sijhawm extrusion granulation txheej txheem, vim qhov kub ntawm 120 ~ 150 Degree, thiab feem ntau ntawm cov enzymes yuav poob lawv cov haujlwm. Ib qho ntxiv, ib puag ncig kub siab dua yuav txhawb nqa cov maitard cov tshuaj tiv thaiv ntawm kev txo cov suab thaj thiab cov amino acids dawb, yog li txo tus nqi ntawm cov protein. Nyob rau tib lub sijhawm, cov kub kub ua rau enzyme inactivation, muaj zog siv hluav taws xob thiab cov neeg luv luv, tab sis cov tsis muaj nqi feem ntau tuaj yeem them nyiaj rau qee yam los ntawm kev ua kom muaj kev zam.

Cov khoom lag luam los ntawm cov khoom lag luam xws li cov zaub mov noj ua noj, cov quav cab, thiab cov kua txob thiab cov kua ntses thiab cov nqaij qaib pub rau tsiaj. Txawm hais tias cov ntaub ntawv raw no muaj cov as-ham, lawv siv tau nyiaj tsawg thaum noj cov kab mob me me, thiab lawv tuaj yeem muaj qe qe, uas cuam tshuam rau kev noj qab haus huv. Cov txheej txheem puffing tuaj yeem txhim kho tus nqi ntawm kev siv khoom noj ntawm cov zaub mov pub mis los ntawm tsiaj txhu thiab nqaij qaib. Piv txwv li, pob kws ua pob kws yuav ua tiav los ntawm kev sib txuas los ntawm kev sib txuas nrog kev ua kom zoo rau kev noj roj ntsha kom zoo, txhim kho nws cov khoom noj muaj txiaj ntsig thiab kev noj haus.
