Hauv cov txheej txheem pub noj niaj hnub no, lub tshuab hluav taws xob me me ntses noj mov extruder yog ib qho tseem ceeb ntawm cov khoom siv rau kev hloov cov ntaub ntawv raw. Los ntawm kev ua haujlwm tshwj xeeb, nws ua cov hmoov nplej thiab cov khoom siv raw rau hauv cov qauv ruaj khov thiab cov khoom noj muaj txiaj ntsig zoo noj pellets, dav siv hauv kev tsim khoom noj rau tsiaj txhu, nqaij qaib, aquaculture, thiab tsiaj. Los ntawm kev txhais, lub tshuab pub extruder yog cov cuab yeej siv tshuab uas siv cov kev sib hloov extrusion ntawm cov ntsia hlau, ua ke nrog cov cua sov ua haujlwm ntawm lub thoob, ua kom tiav cov txheej txheem ua haujlwm hauv lub tshuab, suav nrog kev sib xyaw, gelatinization, thiab kev tsim cov khoom xyaw pub. Nws tus nqi tseem ceeb nyob rau hauv kev txhim kho kev noj zaub mov zoo thiab digestibility.

Lub hauv paus ntsiab lus ua haujlwm ntawm qhuav- hom ntses pluas noj extruder tuaj yeem ua tiav raws li kev kaw- txheej txheem ntawm "extrusion- cua sov-shaping." Ua ntej, ua ntej -kho cov ntaub ntawv raw (xws li cov pob kws crushed, soybean pluas mov, thiab straw) nkag mus rau hauv lub thoob extruder los ntawm kev pub noj mov thiab txav mus rau qhov chaw nres nkoj tawm hauv qab kev sib hloov ntawm cov ntsia hlau. Thaum lub sijhawm txheej txheem no, qhov sib txawv ntawm cov ntsia hlau thiab lub thoob maj mam nqaim, thiab cov khoom siv raw tau raug mob siab heev extrusion, nrog lub siab tsis tu ncua nce mus txog 3-10 MPa. Tib lub sijhawm, cov khoom siv cua sov sab nraud (feem ntau yog hluav taws xob lossis chav cua sov) ua kom cov khoom siv raw rau 80-120 degree, ua rau cov hmoov txhuv nplej siab hauv cov khoom siv raw kom tag nrho cov gelatinize thiab cov proteins kom denature, tsim cov khoom sib xws. Thaum kawg, nyob rau hauv lub siab, cov khoom homogeneous dhau los ntawm ib tug tuag (pwm lub taub hau) nyob rau hauv lub kawg ntawm lub chim thiab txiav mus rau hauv pellets ntawm ib tug ntev lub sij hawm, ua kom tiav tag nrho cov extrusion molding txheej txheem. Qhov kev kub siab no - kub, high-pressure processing method tsis tsuas yog tua cov kab mob tsis zoo hauv cov ntaub ntawv raw tab sis kuj ua rau cov khoom noj khoom haus tsis zoo, txhim kho kev nyab xeeb thiab palatability ntawm cov khoom noj.

Los ntawm ib qho kev xav, cov ntses noj pellet extruder feem ntau muaj tsib lub tshuab tseem ceeb. Lub tshuab pub extruder muaj tsib lub ntsiab lus tseem ceeb: 1) lub tshuab pub mis, nrog rau lub hopper, feeder, thiab tov khoom, lub luag hauj lwm rau uniformly thiab stably pub raw khoom rau hauv lub thoob, tiv thaiv tsub zuj zuj los yog cuam tshuam ntawm pub. Lub feeder feem ntau siv kev hloov pauv zaus, tso cai rau kev hloov pauv ntawm kev pub noj ceev raws li kev xav tau ntau lawm . 2) lub tshuab extrusion, uas muaj cov ntsia hlau thiab lub thoob, yog lub hauv paus ua haujlwm. Cov ntsia hlau lub helical qauv thiab lub thoob lub puab phab ntsa kev ntxhib los mos ua hauj lwm ua ke kom xa thiab extrude cov ntaub ntawv raw. Cov ntsia hlau feem ntau yog ua los ntawm siab -lub zog alloy steel kom tiv taus siab loj thiab hnav. 3) lub tshuab cua sov thiab cua txias, nrog rau cov cuab yeej cua sov sab nraud ntawm lub thoob kom nce qhov kub thiab txias. Qee lub tshuab kuj muaj cov cuab yeej ua kom txias kom tsim nyog cov khoom siv txias tom qab gelatinization, tiv thaiv cov gelatinization ntau dhau uas tuaj yeem cuam tshuam rau qhov zoo . 4) txoj kev tsim, suav nrog kev tuag thiab txiav. Txoj kab uas hla ntawm qhov tuag txiav txiav qhov loj ntawm cov khoom noj pellets, thiab lub cutter txoj kev sib hloov ceev tswj cov pellet ntev, uas tuaj yeem hloov kho raws li qhov xav tau ntawm cov tsiaj sib txawv . 5) lub tshuab kis tau tus mob, muaj lub cev muaj zog, reducer, thiab coupling, muab lub zog rau cov ntsia hlau tig, kom ruaj khov cov khoom siv.

Muab piv rau cov khoom siv ua khoom noj ib txwm muaj, cov txiaj ntsig tseem ceeb ntawm kev pub extruder yog kev ua haujlwm siab thiab kev noj zaub mov zoo. Ib qho nruab nrab - qhov loj pub extruder tuaj yeem tsim tau 1-3 tons ntawm pub rau ib teev, uas yog 2-3 npaug ntawm cov tsoos pellet zeb. The feed pellets it processes have a dense structure and strong foam resistance. Lub sij hawm ua npuas dej ntawm cov dej pub tuaj yeem ncav cuag ntau dua 40 feeb, thiab cov khoom seem seem raug txo kom tsawg dua 5%, uas txhim kho kev siv cov khoom noj thiab txo cov pa phem hauv av.
