Cov txheej txheem Twin Screw Extrusion (DT), tsim los ntawm Clextral rau ntau tshaj 50 xyoo, ua kom cov khoom lag luam txuas ntxiv ntawm cov khoom lag luam zoo nkauj thiab cov qauv tsim kom zoo, siv cov khoom siv xyoob ntoo lossis khoom siv raw. Nws yog siv los tsim ntau yam ntawm Khoom Noj & Khoom Noj Khoom Noj, Cellulose pulps, Bio-sourced plastics thiab tshuaj lom neeg.
YUAV UA LI CAS THIAJ UA LI CAS?
Extrusion ua lub hom phiaj rau physico-chemically hloov txuas ntxiv cov xov paj polymeric khov kho thiab tsim cov khoom lag luam zoo tsim txiaj ntsig ua tsaug rau qhov tseeb raug tswj ntawm kev ua haujlwm.
Clextral ntxaib ntsia hlau extruders suav nrog ob qhov sib txuas, co-tig ntsia hlau tau ntsia rau ntawm kev tuaj txiav rau hauv cov thawv kaw. Vim tias ntau ntawm cov ntsia hlau thiab cov ntsia hlau tsim, ntau cov ntsia hlau txuas ntxiv thiab cov txheej txheem ua haujlwm tuaj yeem tsim raws li cov txheej txheem xav tau. Li no, ntxaib ntsia hlau txuas ntxiv tuaj yeem ua kom thauj khoom, ua haujlwm, sib xyaw, ua noj ua haus, txiab txiav, ua kom sov, ua kom txias, ua kom zoo, ua kom tawv, thiab lwm yam muaj qhov yooj. Qhov loj kom zoo ntawm intermeshing co-rotating ntxaib ntsia hlau extruders yog lawv cov peev xwm zoo sib xws uas muaj cov yam ntxwv tshwj xeeb rau cov khoom extruded thiab ntxiv tus nqi tseem ceeb rau kev ua haujlwm.
Nyob rau hauv ntxaib ntsia hlau extrusion ua, cov ntaub ntawv raw tej zaum yuav khib nyiab (hmoov, granulates, hmoov), kua, slurries, thiab tej zaum muaj roj. Cov khoom rho tawm yog cov tebchaw plastics, hloov tshuaj ua cov tshuaj pleev, cov khoom lag luam rau zaub mov thiab cov khoom lag luam pub zaub mov, cellulose pulps, thiab lwm yam
LUB TXUJ CI NTAWM TWIN NTSIA HLAU EXTRUSION
Ntxaib ntsia hlau extrusion tau dhau los ua tus qauv hauv lub sijhawm hauv ntau lub lag luam vim nws muaj ntau qhov zoo dua ib qho ntsia hlau extrusion:
Ntau cov xwm txheej hauv kev tsim khoom thiab tswj cov khoom zoo
Cov khoom lag luam nce ntxiv vim kev ua tiav, kev ua haujlwm nrawm dua thiab kaw ntawm cov khoom pauv, hloov ceev thiab kev siv tshuab ua kom tiav
Kev ua tau zoo dua, nrog lub peev xwm txheej txheem ntawm ntau hom khoom siv raw
Tshaj tawm hneev taw ua tsaug rau lub zog thiab dej txuag
Yooj yim thiab yooj yim rau kev tswj thiab huv
KOJ PUAS PAUB?
Nws muaj ntau yam txheej txheem txheej txheem txheej txheem
Kev txias txias yog siv los maj mam muab sib xyaw thiab zoo li lub khob noom cookie, tsis muaj qhov ua cua sov lossis ua kom tsis pub dhau lub tshuab extruder. Hauv kev ua zaub mov noj, nws yog siv tsuas yog tsim cov nplej zom thiab khob noom cookie. Cov khoom no tuaj yeem ua cov txheej txheem txuas ntxiv tom qab: qhuav, ci, ntim hauv tshuab nqus, khov, thiab lwm yam.
Kub extrusion muaj cov thermomechanically hloov ua raw cov ntaub ntawv nyob rau lub sijhawm luv luv thiab qhov kub thiab txias hauv qab qhov siab. Hauv kev ua zaub mov noj, feem ntau yog siv los ua biopolymer-raws cov khoom nyoos los tsim cov zaub mov thiab cov khoom lag luam pub zaub mov, xws li npaj cov khoom noj tshais npaj, noj khoom txom ncauj (savory thiab qab zib), cov khoom noj tsiaj, pub pellets, thiab lwm yam.
Ncu tsim kev nthuav tawm, txhais tau tias yaj nthuav tawm ntawm lub qhov rooj tawm tuag vim yog dej ntws tawm, vim li no ua rau cov khoom lag luam nthuav dav ntxiv. Tom qab ua tiav tom qab ntawd txiav txim siab cov cim txheej txheem ntawm cov khoom extruded xws li crispness, crunchiness, hardness, thiab lwm yam. Cov txheej txheem no yog siv los tsim cov khoom noj ncaj qha nthuav tshais, khoom noj txom ncauj thiab cov qhob cij crispy.
Kev sib tshooj co-extrusion sib xyaw nrog kev tsim cov pa thiab nthuav tawm kev txhaj tshuaj, yog li ua rau cov khoom lag luam nthuav dav nrog dual textures. Nws yog tsuas yog siv hauv pluas tshais cov khoom noj thiab khoom noj txom ncauj.
