Dab tsi yog ib qho ntsia hlau ntab ntses extruder tshuab ua? - Kev paub

cov ntsiab lus

Core Parameter Control: Kev sib koom ua ke ntawm kev ceev, kub, thiab siab. Cov ntsia hlau ceev ntawm ib qho - ntsia hlau tsiaj cov khoom noj extrusion tshuab yog ib qho tseem ceeb tswj qhov ntsuas, ncaj qha txiav txim siab lub sij hawm nyob rau hauv cov khoom thiab cov nyiaj ntawm kev sib txhuam thaum tshav kub kub generated. Kev nrawm dua (200-400 rpm) ua rau cov khoom siv nyob hauv lub sijhawm luv dua, kev sib txhuam ntau dua, thiab kev siv zog ntau dua. Thaum tsim cov ntses kib, qhov ceev yuav tsum tau txo (200-250 rpm) kom tsis txhob muaj kev nthuav dav thiab cov pellets nyuaj heev. Thaum tsim cov ntses pub rau cov neeg laus, qhov ceev tuaj yeem nce ntxiv (300-350 rpm) txhawm rau txhim kho cov nyhuv extrusion. Extrusion kub yuav tsum tau hloov kho raws li raw khoom formula. Rau cov qauv nrog cov hmoov txhuv nplej siab siab, tswj qhov kub ntawm 120-140 degree; rau cov qauv nrog cov ntsiab lus muaj protein ntau, tswj qhov kub ntawm 100-120 degree. Qhov kub ntau dhau tuaj yeem ua rau cov khoom siv scorch, thaum kub tsis txaus yuav ua rau tsis tiav melting. Qhov ntau yam rau extrusion siab yog 3-6 MPa. Yog hais tias lub siab tsis txaus, txo qhov tuag orifice txoj kab uas hla los yog nce qhov ceev; yog tias qhov siab dhau lawm, txo qhov nrawm lossis nce tus nqi pub.

Cov txheej txheem kev khiav hauj lwm: Raw Material Pretreatment and Maintenance of the Single -Screw Fish Feed Making Machine. Raw khoom pretreatment yuav tsum ua tau raws li ob qho tseem ceeb: cov ntsiab lus noo noo yuav tsum tau tswj ntawm 10% thiab 14%; Cov dej noo ntau dhau tuaj yeem ua rau cov ntsia hlau lo, thaum tsis txaus noo noo yuav ua rau tsis txaus extrusion. Particle loj yuav tsum yog av rau 80-120 mesh; Qhov loj me me tsis sib xws yuav ua rau muaj kev hloov pauv siab thiab cuam tshuam rau extrusion uniformity. Piv txwv li, hauv kev tsim cov ntses noj, pob kws thiab taum mog yuav tsum tau muab tso rau hauv av rau 100 mesh, thiab cov dej noo ntawm cov khoom siv raw yuav tsum tau sim nrog lub ntsuas dej kom ntseeg tau tias nws ua tau raws li qhov yuav tsum tau ua. Thaum lub sijhawm ua haujlwm ntawm cov cuab yeej siv, kev noj zaub mov tsis tu ncua yuav tsum tau tswj xyuas, uas tuaj yeem pab tau los ntawm cov khoom noj vibrating. Lub siab thiab kub yuav tsum tau saib xyuas nyob rau lub sijhawm; Yog tias qhov hloov pauv ntau dua ± 0.5MPa lossis ± 10 degree, qhov ntsuas yuav tsum tau kho tam sim. Tom qab kaw, cov khoom seem seem nyob rau hauv cov ntsia hlau, extrusion chamber, thiab tuag yuav tsum tau ntxuav tam sim ntawd kom tsis txhob ziab thiab txhaws. Cov ntsia hlau hnav yuav tsum tau kuaj tsis tu ncua; hnav-resistant bushings yuav tsum tau hloov txhua 1000 teev ntawm kev ua haujlwm, thiab cov ntsia hlau yuav tsum tau hloov txhua 2000 teev.

Kev daws teeb meem: Cov phiaj xwm ua kom zoo dua qub thiab hloov kho. Yog tias tsis txaus qhov nthuav dav tshwm sim, lub hau ntswj ceev tuaj yeem nce ntxiv, qhov kub ntawm qhov extrusion tuaj yeem raug tsa, lossis txoj kab uas hla ntawm qhov tuag tuaj yeem raug txo. Yog hais tias qhov particle breakage tus nqi siab dhau lawm, qhov ceev tuaj yeem txo qis, qhov kub thiab txias tuaj yeem txo qis, lossis cov kab uas hla ntawm qhov tuag tuaj yeem nce ntxiv. Yog tias cov khoom siv raw tsis raug xa mus zoo, cov ntsiab lus noo noo thiab qhov loj me ntawm cov khoom siv raw yuav tsum tau kuaj xyuas, lossis cov khoom seem nyob hauv cov ntsia hlau zawj yuav tsum tau ntxuav. Yog hais tias ib qho ntsia hlau ntses pub extruder tshuab ua suab nrov txawv txav, nws yuav tsum tau nres tam sim ntawd los xyuas qhov hnav ntawm cov ntsia hlau thiab extrusion chamber kom tsis txhob muaj kev puas tsuaj rau cov khoom. Piv txwv li, yog tias cov dej tsis kam ntawm cov khoom tau pom tias tsis txaus (tsawg dua 6 teev) thaum lub sijhawm tsim khoom, cov ntsia hlau ceev tuaj yeem nce mus rau 350 r / min kom nce lub siab extrusion, ua rau cov qauv particle ntau dua thiab txhim kho cov dej tsis kam mus rau 8-12 teev.
