Extruders muab faib ua ib leeg-ntsia hlau extruders, ntxaib-ntsia hlau extruders, thiab triple-ntsia hlau extruders. Peb hom extruders no tuaj yeem tsim khoom noj thiab pub, nrog rau qee cov khoom siv raw tshwj xeeb.
Peb hom extruders no tau muab faib ua cov txheej txheem qhuav thiab ntub txheej txheem extruders. Dry-process extruders siv kev sib txhuam thiab shear ntawm lub hau ntsia hlau thiab cov ntsia hlau los tsim kom muaj cua sov, ntxiv los ntawm cov cua sov qhwv ib ncig ntawm sab nraud ntawm lub hau ntsia hlau. Cov cua sov sab nraud ntawm lub nplhaib heats thiab extrudes cov khoom, thiab cov txheej txheem ntawm puffing yog ntau dua nyob rau hauv cov khoom noj me me. Cov khoom noj puffed ua yog crispy thiab muaj ib tug muaj zog tsw. Tsis tas li ntawd, cov chaw ua khoom noj me me kuj tseem siv cov khoom qhuav qhuav, uas muaj cov nqi peev tsawg thiab cov peev nyiaj rov qab sai.
Cov khoom ntub dej extruder siv chav (feem ntau lub siab yog 0.3-0.4mpa thiab qhov kub thiab txias yog 140-150 degree ) kom preheat cov khoom nyob rau hauv lub txias rau 70-100 degree , supplemented los ntawm extruder tus kheej lub tshav kub tiam thiab ntsia hlau chim Cov txheej txheem ntawm cov cua sov sab nraud (nws tuaj yeem yog cov kav dej los yog cov ntawv hluav taws xob hluav taws xob) feem ntau yog siv rau hauv kev tsim cov dej pub, tsiaj noj, extruded. corn feed, soybean feed, etc.
Dab tsi yog qhov txawv ntawm peb cov extruders, thiab lawv qhov zoo yog dab tsi?
1. Ib leeg-ntsia hlau extruder muaj ib tug ntsia hlau los tsim lub extruding chamber. Ib leeg-ntsia hlau feem ntau tsis muaj cua sov sab nraud, thiab tsuas yog nyob rau hauv cov cheeb tsam txias heev los yog thaum cov taum pauv tau tsim los ntawm txoj kev qhuav, cov cua sov sab nraud ntawm cov ntsia hlau yuav ua tiav. Yog li ntawd, nyob rau hauv ib leeg-ntsia hlau extrusion, lub shear tshav kub yog guaranteed los ntawm kev sib hloov ceev, thiab qhov dav ib leeg-ntsia hlau tig ceev yog 480-600 rpm. Nws yog qhov tsim nyog rau puffing nplej nrog ib qho duab thiab tsis yog ib qho duab kheej kheej, rau ripening, thiab tus nqi pheej yig.
2. Lub ntxaib-ntsia hlau extruder yog tsim los ntawm ob lub hau ntswj nyob rau hauv lub puffing chamber, thiab ob lub hau ntswj tau muab sib xyaw ua ke los tsim ib qho chaw meshing. Thaum cov ntaub ntawv tseem tab tom ua haujlwm nyob rau hauv tib lub chamber puffing, cov nyhuv ntawm kev sib xyaw thiab shearing yog nce, yog li nws muaj txiaj ntsig zoo dua li ib leeg-ntsia hlau. Nws yog tsim rau zus tau tej cov mis nyuj sib xyaw. Nws qhov zoo yog: 1. Tsawg ceev, feem ntau 200-300 rpm; 2. Ob lub screws nce kev sib nrig sib shear, yog li cov khoom muaj qib siab ntawm homogenization thiab ruaj khov zoo; 3. Ua kom tag nrho cov cua sov sab nraud thiab kho cov ntsia hlau chim 4. Siv cov kev hloov pauv ceev ceev, kev ua haujlwm ruaj khov thiab txhim khu kev qha; 5. Cov ntsia hlau muaj qhov ua haujlwm ntawm tus kheej, thiab tsis tas yuav tsum tau disassemble lub hau ntsia hlau rau kev ntxuav tom qab nres.
3. Lub peb-ntsia hlau extruder yog tsim los ntawm peb cov ntsia hlau nyob rau hauv lub puffing chamber, thiab peb cov ntsia hlau shear ib leeg, uas yog sib npaug rau peb txheej ntawm twin screws ua hauj lwm ib txhij nyob rau hauv ib tug puffing chamber, nrog peb meshing cov ntsiab lus, yog li lub shearing efficiency. yog siab thiab cov khoom yog yooj yim rau plasticize, tib lub sij hawm, lub siab generated ua ntej puffing yog ntau dua, lub degree ntawm ripening yog qhov zoo dua, thiab cov khoom noj xws li cov protein thiab cov nqaij tshiab ntxiv ntxiv. Kev siv hluav taws xob yog 30% qis dua li ntawm ntxaib-ntsia hlau extruders nrog tib cov zis.
