Kutsanangurwa kweHunhu Hwemhando Yepamusoro uye Kuongororwa Kwezvinhu Zvinopesvedzera muHIGH SHEAR musanganiswa KUGADZIRA
Tekinoroji yeHigh Shear Mixer Granulation inoshandiswa zvakanyanya mumunda wekugadzira mishonga yakasimba. Iyi tekinoroji inowanzo sanganisa zvinhu zvisina kugadzirwa uye exChipuZvinoumba zvakaenzana kuti zvigadzire zvidimbu zve 180-2000 μ m, izvo zvinoshandiswa mumabasa ekudzika senge kudzvanya piritsi, kuzadza kapisi, uye kuisa zvidimbu mubhegi. Kuitwa kwemaitiro ekuisa granulation yakanyorova kwakakosha pakupa zvidimbu zvemhando yepamusoro uye zvakakodzera pasi. Hunhu hwezvidimbu hunokanganisa hunhu hwemhando yepamusoro hwezvigadzirwa, senge chiyero chekunyungudika, mutsauko muhuremu hwepiritsi (musiyano muhuwandu hwekurodha), nezvimwewo. Kazhinji, tinogona kuongorora zvidimbu zvichibva pane zviratidzo zvemuviri zvakaita sekugoverwa kwehukuru hwezvidimbu, porosity, huwandu hwehunyoro, uye kugona kuyerera. Kugohorera kwehukuru hwezvidimbu kunoreva huwandu hwezvidimbu zvinosangana nehuwandu hwehukuru hwezvidimbu hunotarisirwa muchigadzirwa chekupedzisira kusvika kuhuwandu hwezvikamu, izvo zvinogona kuyerwa nekuongorora, laser, uye nzira dzemifananidzo. Sekureva kwechiyero cheindasitiri JB/T 20015, chiyero chekuongorora mashandiro egranulators dzekusanganisa wet ndechekuti chiyero chezvikamu zvestarch yechibage, dextrin, uye shuga powder muchikamu che3:2:1 mushure mekuomeswa hachifanirwe kunge chiri pasi pe75% mukati mehuwandu hwe180-2000 μ m. Makambani anosimbisa saizi yezvikamu zvegranulation zvakanyorova zvichibva pane zvinodiwa zvemaitiro ekudzika, uye huwandu hwehukuru hwezvikamu uye mwero wezvikamu zvinoenderana nezvinodiwa zvechigadzirwa. Kugoverwa kwehukuru hwezvikamu kunotsanangura huwandu hwezvikamu zvehukuru hwakasiyana muhurongwa hwezvikamu, nepo dhigirii rekupararira richiyerwa nehupamhi hwekugoverwa kwehukuru hwezvikamu. Kugoverwa kwehukuru hwezvikamu kunowanikwa kuburikidza nenzira dzehuwandu zvichibva pamhedzisiro yekuona saizi yezvikamu. Kunyangwe kana goho rehukuru hwezvikamu rakanangwa rakafanana, panogona kunge paine misiyano yakakura mukupararira kwehukuru hwezvikamu. Kune mishonga mizhinji, tinosarudza kupararira kwehukuru hwezvikamu zvishoma mukati mehuwandu hwegoho rinotarisirwa rehukuru hwezvikamu zvakanangwa kuti tive nechokwadi chekuenderana kwemhedzisiro yekunyungudika kwemishonga. Upamhi hwekugoverwa kwehukuru hwezvikamu Span hunowanzoshandiswa kuyera huwandu hwekupararira kwekugoverwa kwehukuru hwezvikamu. Nzira yekuverenga ndeiyi inotevera: (1) Muequation: D90- dhayamita yezvikamu inoenderana nenhamba yezvikamu kubva padiki kusvika pakuru inosvika 90% yehuwandu hwese, μm； D10- dhayamita yezvikamu inoenderana nenhamba yezvikamu kubva padiki kusvika pakuru inosvika 10% yehuwandu hwese, μm； D50- dhayamita yezvikamu inoenderana nenhamba yezvikamu kubva padiki kusvika pakuru inosvika 50% yehuwandu hwese, μm。 Kana span yakakura, musiyano mukuru muhukuru hwezvikamu uye kufanana kwakashata; Kusiyana neizvi, inenge yakafanana zvakanyanya. Mufananidzo 1 unoratidza musiyano muhupamhi hwekugoverwa kwezvikamu zvakagadzirwa uchishandisa zvinhu zvakafanana uye ma process parameter akasiyana. Zvinogona kuonekwa kuti kunyangwe goho rehukuru hwezvikamu rakatarwa re180-2000 μ m rakafanana, musiyano muhupamhi hwekugoverwa kwezvikamu wakakosha (curve yebhuruu ine Span diki, curve yeyero ine Span iri pakati nepakati, uye curve yeorenji ine Span yakakura). Saka, kusarudza kukosha kweSpan kwakakodzera zvichienderana nezvinodiwa nemaitiro acho chinhu chakakosha pakuongorora kushanda kwegranulation yakanyorova.
