Ua cov hauv paus ntsiab lus ntawm ntab ntses pub tshuab

1. Raw Material Combination: Add 20%-30% corn flour and wheat flour (high starch content) to the starch formula. Cov hmoov txhuv nplej siab no ua "roj av {{{5 5}} goldating cov neeg sawv cev" -Lawv gelatinize thaum kub, npaj rau cov roj av txuas ntxiv. Ib txhij, ntxiv 5% -10% hmoov nplej (rau viscosity) rau "xauv" pa "pa" pa "huab cua npuas, tiv thaiv lawv kom tsis txhob khiav tawm.

2. High {{- kub sov nyob rau hauv cov ntses pub extruder tshuab: tom qab lub caij nyoog raw rau 110-160℃(zoo ib yam li ua noj mov porridge). Cov hmoov txhuv nplej siab gelatinizes, ua ib lub vircous "pastry." Ib txhij, noo noo nyob rau hauv cov ntaub ntawv raw (12% -14%) hloov mus rau supersaturated vapor, uas yog khov kho encaporulated los ntawm gelatinized encapsulated los ntawm cov hmoov txhuv nplej siab.

3. Lub siab nrawm txo: Chav nthuav tawm mus rau hauv npuas. Thaum lub siab - kub, high- pa cov khoom siv tsis txaus ntseeg lawm, lub siab} Kuv nyiam qhib ib lub taub dej Lub chav nyob rau hauv cov khoom siv raw kuj nthuav tawm sai sai, tsim ntau me me npuas (0.1-0.5 mm hauv lub taub) sab hauv lub granules. Tom qab txias, npuas sollify, thiab particle ntom ua 0.8-0.9 g / cm³ (tsawg dua dej), cia nws ntab.

Ntses Pellet Zeb

Yuav ua li cas ua kom puffed pellets?

1. Thawj kauj ruam yog "cov khoom siv raw sib tsoo." Thawj ntu ntawm cov ntses noj ua cov kab ntau lawm yog "grinder." Cov khoom siv raw xws li pob kws, taum pauv rau hauv lub grinder, uas muaj siab} nrawm nrawm nrawm rau hauv cov hmoov zoo. Feem ntau, nws yuav tsum tau ua av rau 0.8-1.2 millimeters (txog qhov loj ntawm hmoov). Tus nplua cov hmoov, qhov yooj yim nws yog los sib tov tusyees thiab extrudude rau hauv pellets tom qab. Tom qab sib tsoo, cov hmoov yog piped rau "raw khoom lag luam silo" rau kev cia cia ib ntus, tos rau theem tom ntej.

2. Qhov thib ob kauj ruam yog "precision sib xyaw." Cov hmoov nkag mus rau "Tov khoom" los ntawm cov khoom siv raw txhab, thaum cov vitamins, minerals, thiab palatability enhancers ntxiv raws li cov mis. Lub dual - NCEJ NCEJ ROOJ RAU HAUV LUB CAIJ NTUJ TIM THIAB NYEEM RAU NIAM MOV, "Ntau npaum li txhua yam ntawm pub muaj cov khoom noj muaj txiaj ntsig tib yam. Nws lub sijhawm sib xyaw yog feem ntau 5-8 feeb. Kev sib xyaw tsis txaus yuav ua rau qee cov pellets tau muaj txiaj ntsig zoo dua li lwm tus, cuam tshuam rau tsiaj kev loj hlob.

3. Qhov thib peb thib peb yog "siab - kub extrusion," uas yog qhov tseem ceeb tshaj plaws. Cov hmoov sib xyaw ces tau nkag mus rau "Extruder" - Cov khoom siv tseem ceeb ntawm cov zaub mov ntau lawm. Cov ntsia hlau sab hauv extruder rotates nrawm nrawm, thawb cov hmoov sib xyaw rau pem hauv ntej thaum ib txhij cua kub thiab thov siab ntawm 3-5 MPa. Nyob rau hauv cov kub kub thiab siab, cov hmoov txhuv nplej siab hauv cov hmoov sib xyaw cov hmoov gelatinizes, tsim roj. Thaum muab cov qhov tuag ntawm cov extruder, lub siab poob, cov roj nthuav dav, thiab cov hmoov sib xyaw ua cov nplaim hluavtaws ua ke, zoo li Mini paj kws.

4. Cov kauj ruam plaub yog "cua txias thiab kom qhuav." Cov granules freshly yog 80-90℃thiab tseem muag heev, yog li lawv tau xa mus rau "lub tshuab txias." Tus kiv cua nyob rau hauv lub tshuab cua txias tawg, txo qis qhov kub ntawm cov granules mus rau chav sov, ua rau cov granules nyuaj thiab tiv thaiv ntau dua. Lub sijhawm txias yog feem ntau 10-15 feeb; Yog tias txias ua tsis tiav, cov granules yog nquag mus pwm.

5. Lub kauj ruam thib tsib yog "kev tshuaj ntsuam thiab ntim khoom." Cov noob txiv ntoo txias nkag mus rau "kev ntsuam xyuas lub tshuab" kom tshem tawm cov ntaub tawg thiab tsis tsim nyog rau cov granules me me, tawm ntawm cov granules unized, tsim nyog granules. Thaum kawg, cov pellets yog ntim los ntawm qhov hnyav siv lub tshuab "," piv txwv, hauv 20-kilogram hnab, thiab kaw kom ua tiav extruded pub muag hauv khw. Tag nrho cov ntses cov zaub mov pellet kev ua cov kab ntau dua, los ntawm cov khoom lag luam cov khoom tiav, tuaj yeem tsim ob peb puas phaus ntxiv li kev siv zog ntawm kev siv zog.
