Pretzel khob noom cookie Extruder

Kev soj ntsuam ntawm cov zaub mov extruder:
Lub extruder muaj ib khub ntawm cov ntsia hlau thiab lub tes tsho, uas muaj cov haujlwm ntawm kev sib xyaw thiab kneading. Tom qab cov ntaub ntawv raw nkag mus rau hauv lub extrusion chamber, cov ntaub ntawv yog squeezed, rubbed, sheared, thiab lwm yam nyob rau hauv nruab nrab ntawm cov ntsia hlau tes tsho, thiab lub sab hauv siab tseem nce mus txog 4Mpa, thiab qhov kub thiab txias tseem nce mus txog 140 degrees. Qhov kub thiab siab siab nce siab nyob rau hauv 3-7s, thiab cov txheej txheem ntawm cov khoom hloov pauv, ua rau ntxiv gelatinization ntawm starch, denaturation ntawm cov protein, kev puas tsuaj ntawm crude fiber, thiab tua cov kab mob phem xws li Salmonella. Thaum cov khoom kub kub thiab cov khoom siv high-pressure tawm ntawm qhov chaw nres nkoj tawm, nws lub siab yog dheev tso tawm tam sim ntawd, thiab cov dej ib nrab flashes. Tom qab txias, cov khoom muaj ib tug xoob thiab ntxeem tau qauv, thiab nthuav cov khoom yog nyob rau hauv daim ntawv ntawm ib tug loj, flocculent los yog coarse crumbs.

Puff khoom noj txom ncauj extruder

Cov qauv ntawm extruder:
1. Lub feeder yog los xyuas kom meej cov khoom noj thiab ruaj khov, thiab kho tus nqi noj raws li tus nqi tam sim no ntawm lub tshuab extrusion. Feem ntau, electromagnetic ceev tswj lub cev muaj zog lossis lub zaus hloov pauv yog siv rau kev tswj ceev kom hloov pauv cov khoom noj ntawm lub feeder. Lub qhov hluav taws xob ntawm cov khoom noj hopper feem ntau siv cov spiral agitator los pub cov extrusion thiab extrusion seem.
2. Lub puffing chamber yog tsim los ntawm ib tug ntsia hlau, ib lub tes tsho, ib tug template, daim card pob txha, thiab lwm yam. Cov ntsia hlau thiab lub tes tsho lub tes tsho yog ob qho tib si segmented, thiab compression degree yuav tsum tau kho raws li hom thiab cov kev xav tau ntawm puffed. pub hloov lub puffing degree ntawm puffed pub.

Puffed pob kws extruder

Lub hauv paus ntsiab lus ntawm extrusion puffing:
Lub hauv paus ntsiab lus ntawm extrusion puffing yog: cov nplej raw cov ntaub ntawv uas muaj ib tug npaum li cas ntawm cov dej yog kaw nyob rau hauv lub puffing tshuab, rhuab, pressurized los yog mechanically ua rau cov khoom nyob rau hauv ib tug kub thiab kub siab lub xeev. Nyob rau hauv lub xeev no, tag nrho cov ntaub so ntswg Cheebtsam ntawm cov khoom tau sau ntau lub zog, thiab cov qauv ntawm cov khoom yuav mos. Cov dej yog nyob rau hauv lub xeev overheated. Thaum cov khoom siv raw tawm ntawm lub extruder, lub siab dheev poob, cov dej hauv cov khoom nyoos vaporizes tam sim ntawd, thiab lub ntim nthuav dav sai. Thaum cov qauv mus txog qhov txwv elastic, cov npuas tawg, cov pa kub khiav tawm, lub siab sab hauv poob, cov npuas maj mam tawg, thiab cov npuas phab ntsa txuas nrog, tab sis cov txheej txheem no nres ntev ua ntej nws rov qab mus rau qhov qub ntom. Qhov no yog vim hais tias lub khob noom cookie poob dej thiab qhov kub thiab txias, tag nrho cov qauv hardens, thiab cov ntxeem tau thiab xoob daim txhuam cev yog tsau.
Qhov kev hloov pauv hauv cov qauv macroscopic ntawm lub ntim ntim tuaj yeem qhia tau los ntawm puffing degree. Lub expansion degree yog hais txog ntau yam ntawm cov ntim nce ntawm cov khoom tom qab expansion, uas yog qhia los ntawm cov qauv hauv qab no: expansion degree=cross-sectional cheeb tsam ntawm cov khoom nthuav dav / cross-sectional cheeb tsam ntawm lub extruder tuag orifice.
Feem ntau, thaum lub expansion degree siab tshaj 5, cov khoom yog kuj xoob. Raws li cov txheej txheem sib txawv, qhov kev nthuav dav tuaj yeem tswj tau ntawm 10 thiab 20.
