Yuav ua li cas los daws cov ntses me me pub pellet extruder Tuag Pluggging Teeb meem hauv Puff Feed Processing? - Kev paub

cov ntsiab lus

Nyob rau hauv extruded pub ntau lawm, txheeb xyuas qhov tuag qhov blockage hauv cov khoom siv ntses tsis siv neeg ua khoom noj yuav tsum tau saib xyuas cov teeb meem cuam tshuam nrog cov nyhuv extrusion. Dhau li ntawm qhov ib txwm txo qis hauv cov zis thiab qhov siab nce siab, qhov teeb meem tshwj xeeb tshaj plaws yog qhov txawv txav pellet buoyancy- ntses noj uas ib txwm yuav ntab 100% yuav ua rau muaj coob tus dab pellets tom qab thaiv. Qhov no yog vim ib feem ntawm qhov tuag qhov blockage ua rau cov khoom tsis sib xws, ua rau qee cov khoom siv raw nyob rau hauv lub extrusion chamber ntev dhau lawm thiab ua dhau lawm, thaum lwm tus nyob twj ywm rau ib lub sij hawm luv luv thiab tsis tag nrho extruded. Ib txhij, scorched me ntsis (overcooked) los yog ib tug ntxhib, npub nto (undercooked) yuav tshwm sim nyob rau hauv lub pellet nto, thiab ib tug me me ntawm txawv txav chav los ntawm lub qhov hluav taws xob tuag, nrog rau ib tug burnt tsw.

Kev tuav ceev ntawm qhov tuag qhov blockage nyob rau hauv extruded pub ntau lawm yuav tsum tau ib tug ua ke ntawm blockage tshem tawm thiab extrusion system tiv thaiv. Vim tias lub taub hau tuag ntawm cov ntses ntab ntab extruder yog nruj nreem txuas nrog lub tshuab extrusion, cov cua sov yuav tsum tau muab tua ua ntej disassembly, thiab cov cuab yeej yuav tsum tau tso cai kom txias kom qis dua 50℃kom tsis txhob kub hnyiab. Thaum ntxuav lub taub hau tuag, thawj zaug siv ib qho tshwj xeeb scraper tshem tawm cov khoom raw adhering rau saum npoo, ces siv ib tug hlau txhuam nrog ib tug sib xws aperture kom unclog lub tuag qhov. Rau cov tawv nqaij tawv tawv uas tshwm sim los ntawm ntau tshaj - ua noj, lub taub hau tuag tuaj yeem tsau rau hauv 5% citric acid tov rau 60 feeb kom mos ua ntej ntxuav, tsis txhob txhuam tawv uas tuaj yeem ua rau lub taub hau tuag. Tom qab ntxuav, yuav tsum tsis muaj -load test run. Kho cov txheej txheem extrusion kom qis qis dua li qhov qub (kub txo los ntawm 10 degree, siab txo los ntawm 0.5MPa), noj maj mam, saib xyuas cov txiaj ntsig thiab extrusion nyhuv, thiab rov ua dua qhov qub tsuas yog tom qab lees paub tias tsis muaj qhov txawv txav. Piv txwv li, tom qab ntxuav lub taub hau tuag ntawm cov ntses pub extruder, ua ntej teem qhov kub thiab txias rau 120℃thiab lub siab rau 3.5MPa, pub me me ntawm cov khoom, thiab tom qab lub buoyancy ntawm cov pellets rov qab mus rau qhov qub, kho rov qab mus rau qhov qub tsis yog 130℃thiab 4MPa.

Txhim kho qhov tsis zoo thiab tswj cov cuab yeej ntawm cov khoom noj me me ua tshuab kom tsis txhob muaj kev cuam tshuam. Lub hauv paus ntawm puffing parameter hloov yog qhov sib piv ntawm "kub- siab- nrawm": Qhov kub thiab txias (siab tshaj 160 degree) yuav ua rau cov khoom siv raw dhau -gelatinize thiab lo ua ke, thaum qhov kub tsis txaus yuav ua rau cov khoom tsis zoo. Nws yuav tsum tau tswj hwm ntawm 120-140℃raws li cov khoom siv raw; Lub siab yuav tsum ruaj khov ntawm 3-5MPa, nrog kev hloov pauv tsis tshaj 0.5MPa, uas tuaj yeem tswj tau los ntawm kev kho qhov ceev ceev thiab tuag orifice txoj kab uas hla; cov ntsia hlau ceev yuav tsum yog 300-350r / min los xyuas kom meej cov khoom raw nyob twj ywm rau hauv lub puffing chamber rau ib tug nruab nrab lub sij hawm (20-30 vib nas this). Rau kev txij nkawm ntawm cov ntses ntab ntses pub pellet extruder tshuab, disassemble tus tuag thiab ntsia hlau txhua lub limtiam los ntxuav cov khoom seem puffed raw khoom thiab xyuas cov xov xov hnav (hloov yog hnav tshaj 2 hli) kom tsis txhob muaj cov khoom tsis sib xws vim cov xov hlau hnav; calibrate lub ntsuas kub thiab ntsuas ntsuas txhua hli kom paub meej qhov ntsuas ntsuas qhov tseeb, yog li tiv thaiv kev thaiv ntawm ob qho khoom siv thiab qhov ntsuas qhov ntsuas.
