Hloov cov hmoov txhuv nplej siab yog ua raws cov khoom muaj txiaj ntsig ntawm cov hmoov txhuv nplej siab ntuj. Txhawm rau txhim kho cov hmoov txhuv nplej siab thiab nthuav dav nws cov ntawv thov, nws raug kho lub cev, tshuaj, lossis enzymatically los qhia cov pab pawg tshiab ua haujlwm rau cov hmoov txhuv nplej siab lossis hloov qhov loj ntawm cov hmoov txhuv nplej siab thiab granules. Qhov no hloov cov khoom ntuj ntawm cov hmoov txhuv nplej siab (xws li gelatinization kub, thermal viscosity thiab stability, khov -thaw stability, gel zog, zaj duab xis- tsim cov khoom, pob tshab, thiab lwm yam) kom zoo dua rau qee yam kev thov. Cov hmoov txhuv nplej siab uas nws cov khoom hloov pauv los ntawm kev ua haujlwm thib ob yog sib sau ua ke hu ua cov hmoov txhuv nplej siab hloov.
Hloov cov hmoov txhuv nplej siab yog tsim los ua kom tau raws li cov kev xav tau ntawm ntau yam kev lag luam. Piv txwv li, high-kub technology (sterilization ntawm cov kaus poom zaub mov) yuav tsum starch nrog siab -kub viscosity stability; Cov khoom noj khov khov yuav tsum tau cov hmoov txhuv nplej siab nrog khov zoo -thaw stability; thiab cov khoom noj jelly xav tau cov pob tshab zoo thiab zaj duab xis- tsim cov khoom. Qhov thib ob, nws tshawb nrhiav kev siv tshiab rau cov hmoov txhuv nplej siab thiab nthuav nws cov ntawv thov ntau yam. Piv txwv li: kev siv cov hmoov txhuv nplej siab hauv textiles; hydroxyethyl starch thiab hydroxypropyl hmoov txhuv nplej siab los hloov cov ntshav plasma; thiab heev hla-txuas cov hmoov txhuv nplej siab ua ib qho kev hloov pauv rau talc hauv hnab looj tes phais.
Kev txhim kho cov hmoov txhuv nplej siab hauv kuv lub tebchaws tau pib lig, pib thaum xyoo 1980s. Nws tau siv rau hauv ntau lub teb xws li textiles, papermaking, zaub mov, pub, casting, pharmaceuticals, kev tsim kho, thiab roj av. Daim ntawv thov cov hmoov txhuv nplej siab hloov hauv kuv lub teb chaws tseem yog ib qho kev lag luam tawm tshiab, nrog kev sib txawv tseem ceeb ntawm Tuam Tshoj thiab txawv teb chaws nyob rau hauv cov nqe lus ntawm hom, zoo, thiab kev siv ntau yam ntawm cov hmoov txhuv nplej siab hloov. Piv txwv li, muaj ntau tshaj 200 hom ntawm cov hmoov txhuv nplej siab hloov ua los ntawm cov hmoov txhuv nplej siab, thaum Tuam Tshoj mainland tsuas yog tsim ib lub kaum os.
Peb cov hmoov txhuv nplej siab pregelatinized / hloov cov hmoov txhuv nplej siab yog tsim tshwj xeeb rau kev tsim cov hmoov txhuv nplej siab ntau yam, suav nrog cov hmoov txhuv nplej siab pregelatinized. Cov kab ntau lawm no tau tsim los ntawm peb lub tuam txhab raws li kev tshawb fawb thiab kev tshawb fawb ntawm cov thev naus laus zis txawv teb chaws, thiab nws cov kev ua tau zoo thiab cov khoom lag luam tau mus txog hauv ntiaj teb- qib. Nws yog ib qho kev extruder siab heev nrog kev hloov pauv tau yooj yim, ntau yam khoom siv raw, thiab kev ua haujlwm yooj yim, haum rau ntau lub tsev me me.
