cov ntsiab lus

Lub luag haujlwm tseem ceeb ntawm cov khoom noj tsiaj extrusion yog "tsim kom muaj qhov kub thiab txias los ntawm cov ntsia hlau extrusion kom ua tiav cov khoom siv raw maturation thiab puffing." Kev ua haujlwm tiav tuaj yeem muab faib ua plaub theem tseem ceeb: pub thiab xa tawm, extrusion maturation, puffing, thiab txiav thiab trimming. Nyob rau hauv thawj theem, pub thiab conveying, uniformly tov raw khoom (pob kws hmoov, soybean pluas noj, nqaij noj, thiab lwm yam) nkag mus rau hauv lub extruder los ntawm kev pub hopper. Cov ntsia hlau pub mis thawb cov ntaub ntawv raw mus rau lub extrusion chamber ntawm qhov ceev ruaj khov. The core function of this stage is to ensure a continuous and uniform supply of raw materials, avoiding sudden pressure changes in the extrusion chamber due to interrupted feeding, which would affect the maturation effect. Cov tsiaj me me extruders feem ntau siv phau ntawv lossis me me tsis siv neeg pub khoom noj, thaum cov kab ntau lawm tau nruab nrog cov tshuab pub mis ntse uas tuaj yeem kho cov kev pub noj ceev hauv lub sijhawm raws li lub siab nyob rau hauv lub extrusion chamber.

Qhov thib ob theem, extrusion maturation, yog lub hauv paus ntawm cov khoom noj miv extrusion tshuab ua haujlwm. Tom qab nkag mus rau hauv lub extrusion chamber, cov ntaub ntawv raw yog raug rau muaj zog kev sib txhuam thiab shearing quab yuam ntawm cov ntsia hlau thiab lub puab phab ntsa ntawm lub extrusion chamber nyob rau hauv lub siab - ceev tig ntawm cov ntsia hlau (300-600 r / min). Nyob rau tib lub sijhawm, cov ntaub ntawv raw tau txuas ntxiv mus rau hauv qhov chaw kaw, maj mam txo lawv cov ntim. Thaum tshav kub kub tsim los ntawm kev sib txhuam thiab compression sai nce qhov kub ntawm lub extrusion chamber mus rau 120-160 degree, nrog rau siab mus txog 3-8 MPa, tsim ib tug high-temperature, high-pressure ib puag ncig. Nyob rau hauv ib puag ncig no, cov hmoov txhuv nplej siab hauv cov khoom siv raw nqus dej, o, thiab gelatinize (gelatinization tus nqi siab tshaj 85%), thaum cov protein molecular qauv denatures, ua rau nws yooj yim rau cov tsiaj zom thiab nqus. Tib lub sijhawm, qhov kub thiab txias tua ntau dua 99% ntawm cov kab mob phem xws li Salmonella thiab E. coli, ua kom cov tsiaj muaj kev nyab xeeb los ntawm qhov chaw.

Nyob rau hauv lub thib peb theem, extrusion molding, cov khoom nyoos siav, tsis tu ncua thawb los ntawm cov ntsia hlau, mus txog qhov tuag ntawm qhov kawg ntawm lub extrusion chamber thiab yog extruded ntawm kev kub ceev los ntawm cov me me orifices ntawm cov tuag. Cov khoom siv raw yog dheev tso tawm los ntawm qhov siab - kub, siab - siab, kaw ib puag ncig mus rau ib puag ncig ib puag ncig- siab, ua rau cov dej sab hauv mus rau tam sim vaporize thiab nthuav, tsim cov ntxeem tau, xoob granular qauv. Txoj kab uas hla ntawm lub cev tuag tuaj yeem hloov pauv (2-8 hli) kom haum rau kev pub mis rau cov tsiaj ntawm ntau qhov sib txawv.

Qib plaub yog txiav thiab txiav. Cov pellets extruded, tshiab los ntawm cov tuag, yog nyob rau ntawm qhov kub thiab txias (60{7}}80 degree) thiab sib txawv nyob rau hauv ntev, yuav tsum tau txiav los ntawm ib tug teb cutter配套 nrog lub me me tsiaj extrusion tshuab. Lub cutter ceev tuaj yeem hloov kho raws li kev tsim khoom ceev kom paub meej tias qhov ntev ntev (feem ntau 3-5mm). Tom qab txiav, cov pellets nkag mus rau hauv cov txheej txheem txias thiab ziab kom tshem tawm cov dej noo ntau dhau (txo cov dej noo kom qis dua 12%), thaum kawg tsim cov khoom noj khoom haus uas muaj kuab heev. Thoob plaws hauv tag nrho cov txheej txheem, tus extruder ua tiav "ua noj, ua kom tsis muaj menyuam, thiab ua kom zoo" hauv ib qho kev sib xyaw ua ke, tshem tawm qhov xav tau ntawm cov khoom noj khoom haus ntxiv thiab ua rau nws yog ib qho tseem ceeb ntawm cov khoom siv los ua cov khoom noj khoom haus zoo qhuav.

txog Peb

MIKIM cov ntses pub pellet cov kab ntau lawm thiab cov tshuab txhawb nqa muaj txiaj ntsig zoo rau cov nyiaj. Tsis yog lawv pheej yig xwb, tshem tawm cov neeg lag luam nruab nrab thiab tso cai rau me thiab nruab nrab- cov lag luam me (SMEs) thiab cov neeg ua liaj ua teb ntses los yuav cov khoom ua tiav ntawm tus nqi tsim nyog, tab sis lawv kuj khav theeb tshwj xeeb. Cov txheej txheem automated tag nrho, los ntawm cov khoom siv raw crushing thiab meej cov khoom sib xyaw rau extrusion pelleting thiab maturation, yog ua tiav nyob rau hauv ib tug nruam ntws. Qhov no ua rau muaj cov hmoov txhuv nplej siab gelatinization thiab cov txheej txheem pellet zoo, txhim kho kev tsim khoom thiab kev noj zaub mov zoo, ua tiav "tus nqi qis, siab tso zis." Xaiv MIKIM ntses pub pellet ntau lawm kab txhais tau hais tias muaj kev txaus siab ua ntej- muag thiab tom qab- kev muag khoom, suav nrog 24-teev kev txhawb nqa cov neeg siv khoom hauv online, ib qho - xyoo lav ntawm tag nrho lub tshuab, kev txhim kho ntawm qhov chaw, commissioning, thiab kev saib xyuas, thiab ruaj khov ntawm cov khoom seem. Cov neeg siv khoom tuaj yeem yuav nrog kev ntseeg siab thiab siv nrog kev thaj yeeb ntawm lub siab, nrog rau cov nqi zoo thiab kev pabcuam zoo !!!
