Qhov txawv ntawm puffing tshuab thiab extruder

1, Lub ntsiab lus thiab kev ua haujlwm ntawm puffing tshuab thiab extruder
Puffing tshuab thiab extruders feem ntau siv cov khoom siv hauv kev lag luam yas thiab kev lag luam ua zaub mov. Txawm hais tias muaj qhov sib xws ntawm ob, lawv qhov sib txawv tseem ceeb tseem ceeb heev.

Puffing tshuab siv qhov kub thiab txias siab kom tso tawm ntau cov dej vapor nyob rau hauv ib qho instant, ua rau cov khoom nthuav thiab deform, ua cov khoom noj puffed nrog loj ntim, xoob kev ntxhib los mos, crispy thiab kev sib tw saj, thiab yooj yim zom thiab nqus, xws li raws li pob kws flakes thiab paj kws, uas yog cov khoom noj uas muaj ntau tshaj plaws. Lub hauv paus ntsiab lus ntawm kev ua hauj lwm ntawm lub tshuab puffing yog kom sov cov khoom nyob rau hauv tej yam kev mob, ua rau nws saturated vapor siab mus tas li nce, tshaj cov khoom nws tus kheej structural tsis kam thiab ua rau decomposition. Tom qab ntawd, cov dej noo vapor nthuav tawm sai sai, ua rau cov khoom deform thiab nthuav tawm sai sai, yog li ua tiav cov nyhuv puffing.

Extruder yog txheej txheem cua sov thiab yaj cov yas, thiab tom qab ntawd extruding nws los ntawm cov pwm hlau nyob rau hauv siab siab los tsim ntau yam duab ntawm cov khoom yas thiab cov kav dej, xws li cov hniav nyiaj hniav kub, cov khoom ua si, thiab lwm yam. Lub hauv paus ntsiab lus ntawm kev ua haujlwm ntawm extruder yog: tom qab cua sov thiab melting, cov khoom siv thermoplastic yog extruded los ntawm lub taub hau pwm los ntawm kev yuam compression ntawm cov ntsia hlau. Vim lub siab extrusion siab, cov khoom extruded yog nyob rau hauv ib tug dispersed lub xeev, thiab ces tsis tu ncua stretched raws li cov pwm descends, tsim cov yam xav tau sawb los yog ncig txoj kab uas hla perforated yas khoom.

2, Qhov txawv ntawm puffing tshuab thiab extruder
Qhov sib txawv tseem ceeb ntawm cov tshuab puffing thiab extruders yog nyob rau hauv lawv cov qauv kev ua haujlwm, daim ntawv thov, thiab cov khoom siv.
1. Cov qauv kev ua haujlwm sib txawv
Lub tshuab puffing yog tsim los ntawm evaporating thiab puffing cov dej noo hauv cov khoom nyob rau hauv qhov kub thiab txias, thaum lub extruder yog tsim los ntawm kauv extrusion hauv cov yas.
2. Ntau yam kev thov
Puffing tshuab yog tshwj xeeb tshaj yog tsim rau cov khoom noj puffed xws li pob kws flakes, melon noob, thiab lwm yam. Thiab extruders belongs rau cov machinery, raws li ib tug tseem ceeb cov cuab yeej los tsim cov khoom yas, dav siv nyob rau hauv teb xws li kev tsim kho, khoom noj khoom haus, kev ua liaj ua teb, thiab lwm yam.
3. Cov khoom siv sib txawv
Puffing tshuab yog tsuas yog siv rau kev ua cov khoom ntuj xws li nplej, thaum extruders yog siv los ua cov ntaub ntawv polymer xws li PVC, PE, thiab lwm yam.
