Txheem siab -zoo Pregelatinized Cassava Starch cov ntaub ntawv sib xws, ruaj khov slurry yam tsis muaj delamination, dej los nag los yog sedimentation nyob rau hauv standardized stirring thiab dissolution tej yam kev mob. Qhov no yog ib qho tseem ceeb kom zoo dua uas txawv nws los ntawm cov hmoov txhuv nplej siab thiab cov hmoov txhuv nplej siab tsis zoo. Delamination feem ntau tshwm sim los ntawm cov hmoov txhuv nplej siab gelatinization tsis tiav, dej tsis txaus- molecule integration thiab tsis sib npaug particle ntom, uas ua rau qhuav hmoov sedimentation thiab supernatant sib cais. Ua nrog kev siv tshuab pregelatinization, Pregelatinized Cassava Starch hauv paus zam cov teeb meem no thiab xa cov slurry zoo tshaj plaws.
Nyob rau hauv cov ntsiab lus ntawm cov txheej txheem tsim khoom, Pregelatinized Cassava Starch raug siab -kub gelatinization, ziab thiab crushing thaum lub sij hawm tsim khoom. Nws thawj cov hmoov txhuv nplej siab siv lead ua tau raug puas tsuaj tag nrho, yielding tag nrho cov khoom siv nrog cov dej muaj zog - khi muaj peev xwm. Thaum stirring nyob rau hauv dej, hmoov txhuv nplej siab molecules integrate sai thiab meej nrog dej molecules tsim ib tug uniform, ntom thiab ruaj khov network colloid qauv. Cov qauv no muaj zog adhesion thiab siab compatibility nrog dej, tiv thaiv cov khoom -kua sib cais thiab tag nrho tshem tawm delamination, dej los nag thiab sedimentation txaus ntshai.
Raws li cov txheej txheem kev khiav hauj lwm, maj mam ntxiv cov hmoov rau hauv chav -kub dej huv thiab do sib npaug rau 2 mus rau 3 feeb kom txog thaum tag nrho cov hmoov yaj tag yam tsis muaj hmoov qhuav los yog agglomeration. Cov slurry npaj tau zoo ib yam kev ntxhib los mos thiab zoo ib yam thickness tom qab sawv rau 2 mus rau 4 teev nyob rau hauv chav tsev kub, tsis muaj supernatant sib cais nyob rau hauv lub sab sauv txheej thiab tsis muaj starch sediment nyob rau hauv qab, qhia tsis muaj cov tsos mob delamination. Lub sijhawm ntev tsuas yog ua rau me me, tsis muaj teeb meem thickening yam tsis muaj cov khoom tsis zoo-kua sib cais, ua kom tau raws li qhov yuav tsum tau ua, khaws cia thiab kev tsim kho ntawm ntau cov txheej txheem tsim khoom.
me ntsis delamination los yog sedimentation ntsib thaum lub sij hawm siv niaj hnub stems los ntawm kev ua hauj lwm tsis tsim nyog es tsis yog cov khoom tsis zoo hauv lub cev. Piv txwv li, ntau dhau ib qho -lub sij hawm hmoov ntxiv yam tsis muaj kev sib xyaw ua ke ua rau ungelatinized hmoov agglomeration, thiab ua tsis tiav siab heev - cov khoom ntom ntom nti maj mam. Overly dilute slurry nrog rau qhov sib piv dej siab heev yuav ua rau me ntsis dej nag. Cov teeb meem me no tuaj yeem daws tau tag nrho nrog 30 vib nas this ntawm kev nplawm yooj yim ua ntej siv, tsis muaj kev cuam tshuam rau daim ntawv thov kev ua haujlwm lossis cov khoom tiav tiav.
Hauv kev sib piv, cov hmoov txhuv nplej siab zoo tib yam inevitably delaminates tom qab dej soaking, nrog rau cov hmoov txhuv nplej siab ntau thiab supernatant sib cais tom qab luv luv, yuav tsum tau siv tam sim tom qab kev npaj tsis muaj kev cia siab rau. Pregelatinized Cassava Starch ua tau zoo heev txhim kho kev ruaj ntseg thiab kev ua haujlwm txhaum cai. Nws tuav lub xeev ruaj khov thaum npaj ua ntej slurry, kev ua haujlwm txuas ntxiv txuas ntxiv thiab kev tsim kho tsis tu ncua, tiv thaiv kev sib txuas tsis sib xws, kev ua haujlwm tsis zoo thiab qhov chaw tsis zoo los ntawm delamination. Rau kev lag luam xws li kev tsim khoom xyab, cov khoom siv hauv tsev thiab cov khoom noj khoom haus uas xav tau siab slurry stability, cov yam ntxwv no ua kom cov khoom lag luam du, zoo ib yam khoom tiav zoo thiab txo cov khoom siv pov tseg thiab kev ua haujlwm tsis zoo.
