Yuav ua li cas txheeb xyuas thiab daws teeb meem kev tuag nyob rau hauv cov khoom noj ntses me me uas tshwm sim los ntawm cov teeb meem raw khoom? - Kev paub

cov ntsiab lus

Ua ntej, txheeb xyuas cov yam ntxwv ntawm pwm qhov thaiv los ntawm cov khoom siv raw khoom hauv cov khoom siv ntses tsis siv neeg ua kom tsis txhob muaj misdiagnosis. Cov tsos mob ntawm hom kev thaiv no muaj xws li: kev txhaws feem ntau tshwm sim ntawm qhov pib pib lossis tom qab kev hloov pauv ntawm cov khoom siv raw, thiab qhov chaw thaiv qhov chaw yog concentrated ntawm ntug ntawm lub qhov hluav taws xob tuag; cov khoom thaiv cov khoom pov tseg muaj cov impurities pom tseeb (xws li cov xuab zeb, cov hlau tawg) lossis cov ntaub ntawv loj, tsis tau crushed; tib lub sijhawm, cov nyhuv extrusion tsis ruaj khov, nrog cov khoom ua kom tsis zoo thiab tawg. Piv txwv li, thaum siv cov pob kws tshiab los ua cov npua noj, yog tias lub qhov hluav taws xob tuag lub taub hau yuav raug thaiv tsis pub dhau 10 feeb ntawm kev pib, thiab cov khoom siv blockage muaj ntau cov pob kws uas tsis tau tawg, nws tuaj yeem txiav txim siab tias qhov txhaws yog tshwm sim los ntawm cov khoom siv raw khoom me me. Tsis tas li ntawd, yog tias cov khoom siv raw khoom muaj cov dej noo ntau dhau, cov khoom siv thaiv yuav nplaum thiab ua raws li cov phab ntsa sab hauv ntawm lub qhov tuag, ua rau nws nyuaj rau kev ntxuav; yog tias cov ntsiab lus noo noo tsawg dhau, cov khoom thaiv yuav nyuaj, feem ntau cov pob tawv tawv tsim tom qab cov khoom siv raw yog compressed.

Cov phiaj xwm kev daws teeb meem yuav tsum tau muab coj los siv rau kev txhaws hauv cov khoom siv ntses pub khoom noj los ntawm cov teeb meem raw khoom sib txawv. Yog tias qhov thaiv tau tshwm sim los ntawm qhov tsis sib xws ntawm cov khoom siv raw khoom me me (nrog rau cov khoom loj), lub tshuab yuav tsum tau nres tam sim ntawd. Ntxuav lub taub hau tuag thiab puffing chamber ntawm cov khoom siv raw uas tseem tshuav, hloov lub vijtsam (siv lub vijtsam ntawm 80 mesh lossis siab dua), thiab rov- tsoo cov khoom nyoos kom ntseeg tau tias cov khoom me me ua ntej rov pib dua. Yog hais tias qhov blockage muaj impurities, xyuas cov khoom siv tu raw khoom (xws li lub vibrating npo lossis sib nqus sib nqus) rau kev ua haujlwm tsis zoo. Tom qab kho, ua ib tug thib ob tu ntawm raw khoom kom tshem tawm impurities. Yog tias qhov txhaws yog tshwm sim los ntawm cov dej noo ntau dhau ntawm cov khoom siv raw, cov khoom siv raw yuav tsum yog lub hnub- qhuav los yog qhuav siv lub tshuab ziab khaub ncaws kom txo cov dej noo mus rau 12% -15%. Ntxiv ib qho me me ntawm bran (5% -10%) los txhim kho cov khoom ntws. Yog tias cov dej noo tsawg dhau, txau cov dej sov kom tsim nyog rau hauv cov khoom siv raw, do zoo, thiab cia nws sawv ntsug li 30 feeb ua ntej ua. Piv txwv li, thaum ua cov khoom noj ntses uas muaj cov dej noo ntau dhau, ua ntej ziab cov ntses rau 13% cov ntsiab lus noo noo, ntxiv 8% bran thiab sib tov, ces muab tso rau hauv puffing extruder kom zoo tiv thaiv kom txhob lo thiab txhaws.

Txhim kho cov txheej txheem raw khoom pretreatment los tiv thaiv kev txhaws hauv cov ntses me me pub pellet ua tshuab los ntawm qhov chaw. Tsim cov qauv tshuaj ntsuam xyuas raw khoom. Ua ntej txhua batch ntawm raw cov ntaub ntawv nkag mus rau hauv lub warehouse, particle size, ya raws, thiab impurity cov ntsiab lus raug kuaj. Cov ntaub ntawv tsis tsim nyog raug txwv nruj kom nkag mus rau hauv lub tsev rau khoom. Ua tiav cov khoom siv raw khoom pretreatment yog teeb tsa, suav nrog plaub txheej txheem: tu (tshem tawm impurities), crushing (kom paub meej qhov loj me), sib tov (uniforming noo noo thiab muaj pes tsawg leeg), thiab txias (txhim kho cov khoom raw plasticity). Tshwj xeeb tshaj yog rau cov extruders, cov txheej txheem txias tuaj yeem nce qhov kub ntawm cov khoom siv rau 80{12}}90℃los ntawm kev ntxiv chav, cia cov hmoov txhuv nplej siab pib gelatinize, txhim kho cov khoom raw flowability thiab txo txoj kev pheej hmoo ntawm txhaws. Piv txwv li, thaum ua cov khoom noj tsiaj, tom qab txias, cov dej noo ntawm cov khoom raw yog tswj ntawm 14% thiab qhov kub ntawm 85 degrees. Tom qab nkag mus rau hauv lub extruder, nws tuaj yeem dhau los ntawm kev tuag sai, ua rau muaj kev ruaj khov extrusion thiab txo qis qhov txhaws. Tsis tas li ntawd, zam kev tsis sib haum xeeb ntawm cov khoom sib txawv thaum sib xyaw cov khoom sib txawv. Piv txwv li, thaum sib tov siab - cov khoom siv protein thiab cov hmoov txhuv nplej siab siab, qhov sib piv yuav tsum tau tswj xyuas kom muaj kev sib npaug.
