cov ntsiab lus
Kev tsom xam ntawm cov laj thawj tseem ceeb ntawm kev ua tsis zoo hauv cov khoom noj tsiaj extruders. Lub buoyancy ntawm buoyant pub nyob ntawm tus qauv ntxeem tau tsim nyob rau hauv qhov kub thiab txias ntawm lub extruder. Yog tias qhov kub ntawm cov khoom noj tsiaj extruder tsis txaus (qis dua 120 degree), starch gelatinization tsis tiav (gelatinization degree<75%), failing to form a stable network support structure. This results in fewer internal pores and higher density in the pellets, making them prone to rapid sinking. Imbalanced pressure control (below 3MPa) leads to insufficient water vapor expansion during extrusion, resulting in insufficient porosity and decreased buoyancy. Excessive screw speed (above 400r/min) causes insufficient residence time of the raw material in the extrusion chamber, resulting in incomplete extrusion and a pellet buoyancy rate potentially below 80%, far below the industry standard (≥95%). Furthermore, excessively low starch content (<30%) and excessively high moisture content (>14%) nyob rau hauv cov khoom siv raw kuj cuam tshuam rau extrusion nyhuv ntawm extruder, indirectly ua rau tsis zoo buoyancy.
Cov ntsiab lus daws teeb meem. Hais txog kev tswj tsis tau, qhov kub ntawm lub tshuab Dog Food Extruder yuav tsum tau nce mus rau 130-160 degree, thiab lub siab ruaj khov ntawm 4-6MPa. Cov ntsia hlau ceev yuav tsum tau hloov kho raws li cov yam ntxwv ntawm cov khoom siv raw (250-350 r / min) kom ntev lub sij hawm nyob hauv cov khoom siv raw, kom ntseeg tau tias cov hmoov txhuv nplej siab txaus thiab noo noo nthuav dav. Qhov sib piv ntawm cov khoom siv raw yuav tsum tau ua kom zoo dua qub, nce qhov feem pua ntawm cov hmoov txhuv nplej siab xws li pob kws thiab cov hmoov nplej rau 35% -50% los pab txhawb rau extrusion molding. Nyob rau tib lub sijhawm, cov dej noo ntawm cov ntaub ntawv raw yuav tsum nruj me ntsis tswj ntawm 12% -14% kom tsis txhob muaj cov dej noo ntau dhau ua rau adhesion lossis tsis txaus frictional tshav kub tsim. Rau kev tshuaj xyuas cov cuab yeej, tsis tu ncua ntxuav lub taub hau tuag ntawm lub tshuab ntses mini kom tshem tawm cov khoom siv hluav taws kub, tiv thaiv qhov pore los yog hnav, ua kom lub siab poob qis thaum lub sij hawm extrusion, thiab guaranteeing uniform pore tsim.
Kev Tiv Thaiv thiab Kev Tswj Txhua Hnub Cov Ntsiab Lus Ua kom sov lub tshuab ua zaub mov qhuav rau qhov kub thiab txias ua ntej txhua qhov pib kom tsis txhob qis - kub noj; Saib xyuas tus nqi buoyancy hauv lub sijhawm tiag tiag thaum lub sijhawm tsim khoom, kuaj thiab kuaj txhua 30 feeb, thiab ua kom zoo -tune tsis tau sai yog tias qhov buoyancy txo qis; tsis tu ncua calibrate qhov kub thiab siab sensors ntawm lub extruder los xyuas kom meej qhov parameter zaub thiab tsis txhob muaj kev tswj tsis raug vim sensor yuam kev. Lub caij no, cov ntaub ntawv raw yuav tsum tau crushed mus rau 80-100 mesh kom paub meej cov khoom me me, tso lub hauv paus rau kev ua haujlwm zoo ntawm extruder.
