{{01. Umshini wokufaka izinhlanzi ongezelwe ukwenziwa ngokuhlanganisa imiphumela yamanzi, ingcindezi, izinga lokukhishwa komshini lisezingeni le-20 ~ 30} I-gelatinization, i-protein denaturation, ama-enzyme, izingxenye ezinobuthi kanye nokungasebenzi kwama-microorganisms . Ukusebenza kwesitashi esikhiqizwayo kudinga ukufakwa kwesitashi esingu-20% 34 kuye kwangama-37 amosheres (33 kuye ku-36 kg / cm2), umswakama ongu-25 kuya ku-27%; Ngemuva kokukhishwa, ubuningi obuningi kufanele bube ngu-300 g / L, kanye nomswakama 21 ~ {{{22} lapho kukhishwe amaphesenti ama-4 ukusuka lapho kukhishwa khona isikhunta, lapho umswakama ulahlekelwe yi-Steate futhi umswakama we-extrudate uncishisiwe . abaningi Ama-Bubble akhiqizwa ukunciphisa ubuningi . Gcisha okuphakelayo ukuze uthele izinhlanzi ezisheshayo ({31}} Uma ubukhulu bomswakama buka-480g / l bungaphansi ukuntanta, futhi uma kuphakeme kunobukhulu obuningi, kuzocwila .
Izinhlobo 2. izinhlobo nezinhlaka zemishini yokusebenza kwezinhlanzi
Kunezinhlobo eziningi ze-extuders emakethe . ngokuyisisekelo, zingahlukaniswa zibe yi-single-screw extruder kanye ne-trin-screw extruder . okukodwa okukhishwe yi-extruder Ukusika insiza ye-extruder . Isikulufa sokudla okuguquguqukayo ohlelweni lokuphakelayo ludla izinsiza ezivuthiwe ku-pre-conditioner kanye nama-modulator agcwele ama-steam . Inqubo yonke yokushintshashintsha igcina 40-50% Ukwelapha . I-extruder boring ifaka ikhanda nesikulufa Isigaba esiphakathi sisongele futhi sixondele lokho okuqukethwe; Isigaba sokugcina sesikulungisa kancane ama-tapeters, ukuze impahla ibunjwe kumkhiqizo wokugcina .
