Temperature parameter control: Precise temperature control nyob rau txhua ntu. Lub tshuab extrusion ntawm lub tshuab ziab khaub ncaws ntub dej yog feem ntau muab faib ua peb qhov kub thiab txias -tswj seem: pub, compression, thiab puffing. Cov kev teeb tsa no yuav tsum raug teeb tsa raws li cov yam ntxwv ntawm cov khoom siv raw thiab hom ntses pub. Qhov ntsuas kub ntawm qhov pub mis yog tswj ntawm 60-80℃kom preheat cov ntaub ntawv raw, txhim kho dej nqus, thiab npaj rau kev rov ua dua tom ntej. Qhov kub ntawm qhov compression yog nce mus rau 100{18}}120℃kom cia cov ntaub ntawv nyoos los pib yaj thiab cov hmoov txhuv nplej siab pib gelatinization. Lub puffing seem kub ncav cuag 120-160 degree, qhov twg cov ntaub ntawv raw yog tag nrho puffed nyob rau hauv siab kub thiab siab, thaum tib lub sij hawm tua cov kab mob phem (xws li E. coli thiab Salmonella). Piv txwv li, thaum tsim cov khoom noj muaj protein ntau hauv hiav txwv bass thaj tsam pub, ntu pub mis yog 70 degree, ntu compression 110 degree, thiab puffing seem 150 degree. Kub kub txhawb cov protein denaturation thiab txhim kho digestibility. Thaum tsim cov khoom noj rau cov ntses kib, qhov puffing seem kub yuav tsum tau txo mus rau 120-130℃kom tsis txhob poob ntawm cov as-ham-rhiab heev (xws li cov vitamins) vim qhov kub thiab txias. Kev tswj qhov kub thiab txias yog ua tiav los ntawm kev sib koom ua haujlwm ntawm cov khoom siv cua sov thiab chav dej. Kev saib xyuas lub sijhawm ntawm qhov ntsuas kub yog qhov tsim nyog los xyuas kom meej qhov ua yuam kev hauv ± 5 degree.

Lub tshuab ua khoom noj dev ntub dej yuav tsum muaj kev sib koom tes siab thiab kev tswj ceev kom ntseeg tau tias qhov zoo tshaj plaws puffing thiab tsim cov teebmeem. Qhov siab npaum li cas rau lub extrusion chamber yog 4-6 MPa. Lub siab ntau dhau tuaj yeem ua rau kev nthuav dav thiab nkig pellets; Tsis txaus siab ua rau tsis txaus puffing thiab tsis zoo pellet compaction. Kev tswj lub siab tuaj yeem ua tiav los ntawm kev kho cov ntsia hlau ceev thiab txoj kab uas hla ntawm qhov tuag: ua kom cov ntsia hlau ceev (250-350 r / min) ua kom lub sijhawm nyob ntawm cov khoom siv raw hauv lub extrusion chamber, txo qhov siab; txo qhov ceev (200-250 r / min) ncua lub sijhawm nyob, nce siab. Txoj kab uas hla ntawm qhov tuag yuav tsum raug xaiv raws li cov khoom noj ntses (1-2 hli rau kib, 3-5 hli rau cov neeg laus noj ntses). Cov orifices me me ua rau muaj kev ntxhov siab ntau dua. Nyob rau tib lub sijhawm, kev pub mis yuav tsum tau sib koom ua ke nrog kev ceev. Rau 100 kg / h qauv, kev pub mis ceev yuav tsum tau tswj ntawm 80-100 kg / h kom ntseeg tau tias cov khoom siv raw ruaj khov thiab tsis txhob muaj qhov hloov pauv siab.

Cov ntses ntub dej pub extruder tshuab yuav tsum muaj qhov sib npaug ntawm qhov ntsuas kom ntseeg tau tias muaj dej noo thiab kub. Chav siab yuav tsum tau tswj ntawm 0.3-0.5 MPa thiab chav kub ntawm 130-150℃kom ntseeg tau tias kev sib xyaw sai ntawm chav nrog cov khoom siv raw thiab cov dej tsis sib xws thiab cua sov. Yog tias lub zog siab dhau lawm, cov dej rov ua kom zoo dua yuav qis, thiab cov khoom siv raw kub yuav nce qeeb; yog tias qhov siab dhau lawm, nws tuaj yeem yooj yim ua rau cov dej noo ntau dhau hauv qee qhov chaw, ua rau muaj qhov tsis sib xws. Hauv kev xyaum, lub tshuab lim dej yuav tsum tau kuaj xyuas tsis tu ncua kom tshem tawm cov condensate thiab impurities kom tsis txhob cuam tshuam rau chav dej. Lub chav regulating valve yuav tsum tau rhiab heev thiab txhim khu kev qha, thiab cov dej ntxiv yuav tsum tau kho kom zoo nyob rau hauv lub sij hawm raws li lub extrusion chamber kub thiab siab. For example, if the extrusion chamber temperature is found to be low (below 120℃) during production, the steam pressure can be appropriately increased to 0.45 MPa to increase the water replenishment amount, while simultaneously reducing the screw speed and extending the raw material residence time to ensure the temperature reaches the target.

txog Peb

MIKIM cov ntses pub pellet cov kab ntau lawm thiab cov tshuab txhawb nqa muaj txiaj ntsig zoo rau cov nyiaj. Tsis yog lawv pheej yig xwb, tshem tawm cov neeg lag luam nruab nrab thiab tso cai rau me thiab nruab nrab- cov lag luam me (SMEs) thiab cov neeg ua liaj ua teb ntses los yuav cov khoom ua tiav ntawm tus nqi tsim nyog, tab sis lawv kuj khav theeb tshwj xeeb. Cov txheej txheem automated tag nrho, los ntawm cov khoom siv raw crushing thiab meej cov khoom sib xyaw rau extrusion pelleting thiab maturation, yog ua tiav nyob rau hauv ib tug nruam ntws. Qhov no ua rau muaj cov hmoov txhuv nplej siab gelatinization thiab cov txheej txheem pellet zoo, txhim kho kev tsim khoom thiab kev noj zaub mov zoo, ua tiav "tus nqi qis, siab tso zis."
