Dab tsi yog qee qhov teeb meem tshwm sim thaum siv lub tshuab nqus ntses pub extruder los tsim cov pellets ntab? - Kev paub

cov ntsiab lus

Cov teeb meem 1: Pellet buoyancy tsis zoo, qee qhov los yog tag nrho lawv tog rau hauv qab. Ua rau muaj xws li: extrusion kub tsawg dhau (tsis txaus cov hmoov txhuv nplej siab gelatinization), tsis txaus siab (ob peb npuas formations), thiab cov khoom raw cov hmoov txhuv nplej siab tsawg (hauv qab 25%). Kev daws: Ua kom qhov kub ntawm cov khoom siv ntses tsis siv neeg ua zaub mov rau 130-140℃thiab pib tsim khoom tom qab qhov kub thiab txias; nce lub extrusion siab mus rau 3-5MPa los ntawm kev hloov cov tuag nrog ib tug me me aperture (xws li, hloov ib tug 4 hli tuag nrog ib tug 3 hli tuag) los yog ua kom lub feed ceev; ntxiv cov hmoov txhuv nplej siab xws li pob kws lossis nplej rau cov khoom siv raw kom nce cov hmoov txhuv nplej siab rau 25% -40%. Piv txwv li, thaum tsim cov khoom noj khoom haus floating, cov hmoov txhuv nplej siab tsis txaus ua rau cov pellets hauv dej; ntxiv 20% pob kws hmoov nce lub buoyancy tus nqi ntawm 60% mus rau ntau tshaj 95%.

Cov teeb meem 2: Pellet hardness tsis txaus, yooj yim disintegrating hauv dej. Ua rau: Kub extrusion ntau dhau (tshaj -expansion), siab ceev ceev heev (lub sij hawm luv luv ntawm cov khoom nyob hauv), thiab cov khoom siv raw cov ntaub ntawv noo noo ntau dhau (tshaj 15%). Cov kev daws teeb meem: 1. Txo qhov kub ntawm lub ntab ntses pub pellet extruder tshuab los ntawm 5-10 degree, tswj nws ntawm 120-130 degree; txo cov ntsia hlau ceev mus rau 300-350 r / min kom nce cov khoom siv raw khoom nyob rau lub sijhawm; qhuav cov ntaub ntawv raw noo noo mus rau 12% -15%. Tsis tas li ntawd, cov ntsiab lus ntawm cov protein nyob rau hauv cov khoom siv raw tuaj yeem tsim kom tsim nyog (xws li, los ntawm kev ntxiv cov ntses los yog taum mog) los txhim kho pellet binding zog. Piv txwv li, thaum cov ntses me me pub extruder ua rau cov khoom noj rau crucian carp, qhov kub thiab txias heev ua rau cov pellets ua nkig. Txo qhov kub ntawm 145℃mus rau 135℃ho txhim kho pellet hardness, thiab dej stability mus txog 8 teev.

Cov Teeb Meem 3: Qhov loj me pellet tsis sib xws thiab qhov sib txawv loj hauv buoyancy. Ua rau: Tsis sib luag tuag lub taub hau hnav, kev hloov pauv loj hauv kev pub noj ceev, thiab cov khoom siv raw khoom tsis sib xws. Cov kev daws teeb meem: Hloov lub taub hau tuag ntawm qhov zoo tshaj plaws ntses pub pellet extruder tshuab kom ntseeg tau tias cov aperture zoo ib yam; tshawb xyuas lub extruder cov khoom noj khoom haus, ceev cov khoom sib kis, thiab tsis txhob noj tsis sib xws; re- tsoo thiab tshuaj xyuas cov khoom siv raw kom ntseeg tau tias qhov loj me me (80-100 mesh). Tsis tas li ntawd, cov ntsuas ntsuas siab yuav tsum tau saib xyuas hauv lub sijhawm tiag tiag thaum lub sijhawm tsim khoom. Yog tias qhov hloov pauv siab tshaj ± 0.5MPa, tus nqi pub yuav tsum tau kho tam sim ntawd kom ntseeg tau tias muaj kev ruaj ntseg. Rau ntxaib-ntsia hlau ntses pub extruders, lub meshing clearance ntawm ob lub hau kuj yuav tsum tau kuaj xyuas. Kev tshem tawm ntau dhau tuaj yeem ua rau tsis sib xws ntawm cov khoom siv raw thiab cuam tshuam qhov sib xws ntawm buoyancy.

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 kev tsim cov 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!
