Cov kauj ruam ntau lawm

Thawj kauj ruam hauv kev ua zaub mov dev nrog lub tshuab tsis siv neeg dog dig khoom noj yog raw khoom pretreatment, uas yog ib qho tseem ceeb los xyuas kom meej lub uniformity ntawm cov khoom tiav.

Ua ntej, cov khoom siv tseem ceeb xws li pob kws, taum noj mov, thiab cov nqaij noj yuav tsum tau kuaj xyuas kom tshem tawm cov impurities thiab cov khoom lwj. Tom qab ntawd, cov khoom siv raw yog pulverized mus rau 80-120 mesh siv lub ultra-zoo grinder. Cov dej noo ntawm cov khoom siv pulverized yuav tsum tau tswj ntawm 10% thiab 15%, ib qho tseem ceeb ntawm cov txheej txheem qhuav-yog tias cov ntsiab lus noo noo siab dhau lawm, nws yuav ua rau cov khoom siv raw los lo ua ke thiab txhaws lub tshuab me me pub extruder; yog tias cov ntsiab lus noo noo tsawg dhau, nws yuav tsis tsim kom muaj cua sov txaus, cuam tshuam rau kev ua noj. Thaum lub sij hawm pretreatment, ib tug sib nqus separator kuj yog siv los tshem tawm cov hlau impurities los ntawm raw cov ntaub ntawv los tiv thaiv hnav ntawm extruder ntsia hlau thiab tuag.

Cov kauj ruam thib ob yog kev sib tov meej. Raws li cov qauv, cov hmoov nplej pulverized, nqaij noj, zaub hmoov, thiab vitamin thiab mineral premix yog poured rau hauv ib tug ntxaib -shaft paddle tov khoom thiab stirred rau 5-10 feeb kom ntseeg tau tias ib tug sib tov ntawm ntau tshaj 95%. Kev sib xyaw tsis sib xws yuav ua rau poob ntawm qee cov as-ham hauv cov zaub mov dev, cuam tshuam rau tus dev noj qab haus huv. Tom qab sib tov, cov khoom siv raw nkag mus rau hauv lub tshuab ua zaub mov noj khoom noj khoom haus los ntawm cov yeeb nkab kaw kaw kom tsis txhob muaj kev sib kis.

Qhov thib peb kauj ruam yog lub hauv paus extrusion thiab maturation txheej txheem, tus ntsuj plig ntawm cov txheej txheem qhuav. Cov extruder qhuav yuav tsum tsis muaj dej ntxiv lossis chav; nws tso siab rau qhov siab -kev sib hloov ceev ntawm cov ntsia hlau (300-600 rpm) thiab kev sib txhuam hnyav ntawm cov ntsia hlau thiab lub tshuab extrusion chamber los tsim kom muaj qhov kub thiab txias, tso cai rau cov khoom siv raw kom paub tab ntawm 120-160℃thiab 3-8 MPa. Qhov kub kub tua ntau tshaj 99% ntawm cov kab mob uas muaj teeb meem xws li Salmonella, thaum lub siab siab siab siab gelatinizes cov hmoov txhuv nplej siab (gelatinization tus nqi ntau dua 85%) thiab nruab nrab denatures cov protein, txhim kho cov khoom noj dev digestibility thiab nqus tus nqi. Nyob rau tib lub sijhawm, cov khoom siv raw yog ejected los ntawm qhov me me ntawm Aub Khoom noj khoom haus Extruder tuag, tam sim ntawd tso siab rau daim ntawv ntxeem tau, nkig granules. Txoj kab uas hla ntawm qhov tuag tuaj yeem hloov kho raws li qhov xav tau (2-8mm) los tsim cov khoom noj dev uas haum rau cov dev ntawm ntau qhov sib txawv.

Kauj ruam plaub yog ziab thiab txias. Cov khoom noj dev extruded muaj cov dej noo ntawm kwv yees li 20% -25%, thiab yuav tsum tau nkag mus rau lub tshuab ziab khaub ncaws mesh. Lawv qhuav nyob rau hauv ib puag ncig huab cua kub ntawm 80-100℃rau 15-20 feeb kom txo cov dej noo kom qis dua 12%, ncua lub neej txee. Cov granules kub kub (siab tshaj 60 degree) tom qab ziab yuav tsum tam sim ntawd nkag mus rau hauv lub tshuab cua txias, qhov uas yuam cua khiav kom txias rau hauv chav sov kom tsis txhob muaj cua sov los ntawm qhov ua rau cov granules ua ntub thiab pwm. Cov kauj ruam kawg yog kev tshuaj xyuas, muab qhab nia, thiab ntim khoom. Tsis tsim nyog granules tawg thiab loj granules raug tshem tawm, thiab cov khoom noj dev tsim nyog tau ntim rau hauv lub hnab kaw, ua tiav tag nrho cov txheej txheem qhuav qhuav.

Cov ntsiab lus

Thoob plaws hauv cov txheej txheem, qhov kev ua tau zoo ntawm Tsiaj khoom noj khoom haus tshuab rau hauv tsev ncaj qha txiav txim siab qhov zoo ntawm cov khoom tiav. Lub siab -zoo qhuav extruder muaj ntau- cheeb tsam kub tswj, uas tuaj yeem kho qhov kub ntawm lub extrusion chamber kom tsis txhob scorching lossis undercooking ntawm raw cov ntaub ntawv; qhov hnav- cov hlau nplaum tiv taus ua kom ntev- lub sijhawm ua haujlwm ruaj khov thiab txo cov nqi kho khoom siv.
