Khoom noj khoom haus extruders tau siv dav hauv kev lag luam khoom noj rau kev tsim khoom noj ntau yam, xws li noodles, biscuits, chocolates, thiab cheeses. Ib leeg-ntsia hlau thiab ntxaib-ntsia hlau extruders yog ob hom khoom siv extrusion uas siv rau lub hom phiaj no. Thaum ib leeg-ntsia hlau extruders tsuas muaj ib tug ntsia hlau, ntxaib-ntsia hlau extruders muaj ob tug ntsia hlau. Lawv kuj txawv ntawm lawv cov qauv kev ua haujlwm, kev tsim khoom thiab kev ua haujlwm, thiab kev siv ntau yam.
Thaum xaiv ntawm ob hom extruders, ntau yam yuav tsum tau xav txog. Piv txwv li, kev tsim khoom thiab kev ua haujlwm ntawm kev lag luam yuav txiav txim siab hom extruder uas tsim nyog tshaj plaws. Twin-screw extruders feem ntau ua tau zoo dua li ib leeg-ntsia hlau extruders, ua rau lawv zoo tagnrho rau cov lag luam uas xav tau ntau lawm. Cov yam ntxwv ntawm cov khoom noj khoom haus kuj ua lub luag haujlwm hauv kev xaiv ntawm extruder, nrog rau ib leeg-ntsia hlau extruders yog tsim nyog rau cov khoom noj khoom haus qis dua xws li biscuits thiab noodles, thaum ntxaib-ntsia hlau extruders zoo dua rau cov khoom noj khoom haus viscosity siab dua xws li chocolate thiab cheese. .
Cov peev nyiaj thiab tus nqi yog lwm yam tseem ceeb uas yuav tsum xav txog thaum xaiv ntawm ob hom extruders. Twin-screw extruders feem ntau kim dua ib leeg-ntsia hlau extruders, yog li cov lag luam yuav tsum xav txog lawv cov peev nyiaj thiab cov nqi cuam tshuam ntawm kev xaiv ib hom extruder dua lwm tus. Cov kev cai tseem ceeb kuj tseem ceeb, vim tias cov ntsia hlau ntxaib extruders zoo dua tuaj yeem tswj cov txheej txheem extrusion ntawm cov khoom noj khoom haus.
Thaum ib leeg-ntsia hlau extruders muab kev yooj yim thiab cov nqi qis dua, ntxaib-ntsia hlau extruders muab ntau yam thiab cov khoom zoo dua. Raws li kev lag luam hloov zuj zus thiab xav tau ntau dua, ntau yam, zoo, thiab hloov tau yooj yim, cov neeg ua haujlwm ntawm ib leeg-ntsia hlau extruders feem ntau ntsib teeb meem ntawm seb puas yuav ntxiv cov cav tov ib leeg lossis hloov mus rau ntxaib-ntsia hlau extruders. Feem ntau, cov tuam txhab xaiv hloov mus rau kev ua ntxaib-ntsia hlau vim nws muaj ntau yam txiaj ntsig, suav nrog ntau yam kev xaiv ntawm cov khoom siv, kev nce qib, kev txhim kho zoo, ntxiv kev yooj yim, kev tswj cov txheej txheem zoo dua, thiab cov nqi khiav qis dua.
Twin-screw extruders tuaj yeem ua tiav ntau qhov dav thiab ntau yam ntawm cov khoom xyaw, suav nrog oat hmoov, starches, thiab cov khoom loj me me. Lawv muab cov peev txheej ntau dua thiab kev txuag nyiaj hauv kev pib thiab nres cov txheej txheem, ntxuav, thiab hnav. Twin-ntsia hlau extruders tseem tuaj yeem tsim cov khoom noj txom ncauj uas muaj txiaj ntsig zoo nrog ntau hom duab, textures, thiab nto tiav, ua rau lawv zoo tagnrho rau cov tuam txhab loj hlob, uas yuav tsum tau ua kom tau raws li qhov kev thov rau cov khoom zoo nkauj, cov khoom lag luam uas muaj kev sib txawv hauv kev lag luam coob. . Hauv kev xaus, cov lag luam yuav tsum xaiv ib leeg-ntsia hlau los yog ntxaib-ntsia hlau extruder raws li lawv tus kheej xav tau, khaws cia rau hauv lub siab ntev ntawm lawv qhov kev txiav txim siab.
