Single screw extruder: yakakodzera kune imwechete zvinhu uye zvipfuyo zvakajairika uye huku yekudyidzana feed.
Twin screw extruder: inowanzo shandiswa mukugadzira yakakwira kukosha-yakawedzerwa yemvura uye chikafu chemhuka, senge eel, turtle, uye chikafu chehove dzechidiki, nekuti mitengo yezvinhu izvi zvinotengeswa pamusika inokwana kubhadhara mutengo wekugadzira zvigadzirwa uchishandisa. twin screw technology; Pamusoro pezvo, kumwe kudya kwakakosha kwemumvura, senge chikafu chemumvura (chine dhayamita ye0.8 ~ 1.5mm), chikafu chine mafuta akawanda emumvura, uye chikafu chine huwandu hudiki hwekugadzira asi chinogara chichichinja fomula, inodawo kugadzirwa uchishandisa twin screw extruder. .
Zvinofanira kujekeswa kuti misiyano iri pamusoro haina chokwadi. Semuyenzaniso, tinokurudzira kushandisa masiruuru maviri kugadzira chikafu chemumvura, asi iko zvino makambani mazhinji anoshandisa masiruuru ega kugadzira chikafu chemumvura. Pane misiyano pakushandiswa kwezviviri izvi pakudya kwemvura. Muchidimbu, zvichienzaniswa ne screw imwe, kaviri screw ine zvinotevera zvakanakira:
① Iko kuchinjika kwezvinhu zvakakura, izvo zvinogona kuenderana nekugadziriswa kwepamusoro viscosity, yakaderera viscosity, yakakwira mafuta, yakakwira mwando kana viscosity, ine mafuta, yakanyorova zvakanyanya, uye zvimwe zvinhu zvinogona kutsvedza mune imwe screw (SSE) .
② Pane zvishoma zvirambidzo pahukuru hwezvinhu zvakabikwa, izvo zvinogona kuchinjika kune kugadzirwa kwezvinhu kubva kuhupfu kusvika kune yakaomarara poda particles uye imwe screw processing yemidziyo ine particle size kunze kweiyo yakatarwa.
③ Kuyerera kwezvinhu mukati medhiramu kwakawedzera yunifomu, uye chiutsi, mvura, nezvimwe zvinogona kuwedzerwa kuti zvizadzise zvinodiwa zvechigadzirwa.
④ Hunhu hwemukati uye hwekunze hwechigadzirwa huri nani, hunogona kuwana yakanaka kwazvo homogeneous mamiriro uye kuita kuti mamolecular chimiro chechinhu chakarongeka zvakaenzana. Iyo yepamusoro inotsvedza panguva ye extrusion process. Zvigadzirwa zvechigadzirwa zvine yakakwirira kufanana uye yakanaka kufanana.
⑤ Iko kuibva uye homogenization mhedzisiro iri nani, kazhinji ine starch yekuibva dhigirii inopfuura 95%, iyo inogonesa yakagadziriswa chikafu chemumvura kuchengetedza kugadzikana mumvura, kudzivirira kurasikirwa kwechigadzirwa chinovaka muviri, uye kuve nyore kugaya nekunwa.
⑥ Goho repamusoro pasi pesimba rakaenzana. Kuita kwakanaka kwekusanganisa kunogonesa homogenization yenguva yekupisa inogamuchirwa nezvinhu, inomhanyisa dhigirii rekukura kwezvinhu, inoderedza kushanduka kwekushisa kwezvinhu, uye inovandudza kubuda kwezvigadzirwa zvakaburitswa.
⑦ Kusiyana-siyana kwechigadzirwa uye kuchinjika kwakakura, uye inokwanisa kugadzira chikafu chemvura chemumvura, fomula yemafuta yakakwira, hunyoro hwakanyanya, zvigadzirwa zvekunamatira, uye mavara mazhinji, rudzi rwesangweji, uye zvigadzirwa zvine chimiro chakakosha.
⑧ Kushanda kwekuita kuri nyore, uye kumhanya kwespindle kunogona kugadziridzwa zvinoenderana nezvinodiwa zvechigadzirwa chakagadziriswa. Nekuda kweiyo yekuzvichenesa ficha, kuchenesa kuri nyore kwazvo, uye hapana chikonzero chekuparadzanisa michina mushure mekugadzirisa kwega kwega.
⑨ Mativi ari munjodzi anopfeka zvishoma. Mafungiro akajairika ndeekuti screw imwe chete ine shoma shoma. Muchokwadi, panguva yemapatya screw extrusion process, nekuda kweiyo yakagadzikana yekufambisa zvinhu uye hunhu hwekuyerera kwezvinhu, kupfeka kwezvinhu zviri pascrew uye mukati memukati sleeve yedhiramu idiki pane iyo imwe screw. Kunyangwe iyo nhamba yescrews iri imwezve set, mutengo wezvishongedzo uchiri wakaderera pane weiyo screw imwe chete.
⑩ Mari yekugadzira yakaderera. Nekuda kwekugadzikana kwakanaka kwekushanda kweiyo twin screw modhi, kune mashoma emitengo yekutanga, kushomeka kwemvura uye gasi tsvina, kushomeka kwemari yevashandi, kukwirira kwekutamisa kupisa kwakanaka, goho rakawanda, uye yakakwira magetsi ekuburitsa zviratidzo mukugadzirisa chikafu. Pamusoro pezvo, mutengo wezvishandiso zvakare wakaderera, uye mutengo wekupedzisira wekugadzira uchiri wakaderera zvakanyanya kana uchienzaniswa ne screw imwe.
Imhaka yekuti mabhenefiti mazhinji epatwin screw kana achienzaniswa nescrew imwe mukugadzira chikafu chemumvura chatinosimudzira kusarudzwa kwetwin screw extruder kana mamiriro achibvumidza mune zvese.
Aya anotevera matanho anotorwa kana uchishandisa twin screw extruder:
1. Kuchengetedzwa kwebasa:
-Usati washandisa twin screw extruder, zvinofanirwa kujairana nemashandisirwo emidziyo, matanho ekuchengetedza, uye mashandisiro echimbichimbi ekuvhara maturusi.
-Vashandi vanofanirwa kupfeka midziyo yekudzivirira inoenderana kuti vadzivise tsaona uye kukuvara kunogona kuitika panguva yekushanda.
-Iva nechokwadi chekuchengetedzwa kwenzvimbo yekushanda yakatenderedza midziyo uye kudzivirira njodzi dzakadai sekutsvedza uye kudhumhana.
2. Kugadziriswa kwemidziyo:
-Kugara uchichengetedza uye chengetedza twin screw extruder, kusanganisira kuchenesa, lubrication, kusimbisa mabhoti, etc. Iva nechokwadi chokuti michina iri mumamiriro ekushanda akanaka.
-Gara uchiongorora zvinhu zvinopfekwa zviri nyore senge screws, washers, uye maassemblies, uye wozvitsiva panguva yakakodzera kuti uone kushanda kwakajairika kwemidziyo.
-Gadzira zvirongwa zvekugadzirisa zvinoenderana zvichienderana nehuwandu hwekushandisa kwemidziyo uye nharaunda yekushanda kuti ive nechokwadi chekushanda kwakasimba kwenguva refu kwemidziyo.
3. Kuchinja kwezvinhu:
-Twin screw puffing machines ine zvakakwirira zvinodikanwa zvezvinhu zvakasvibirira, uye zvakasiyana mbishi zvinhu zvingada akasiyana puffing process paramita uye nzira dzekushandisa.
-Pakusarudza michina, zvinodikanwa kuve nechokwadi chekuti modhi uye maratidziro emidziyo akakodzera tekinoroji inodiwa yekugadzirisa zvichienderana nehunhu hwezvigadzirwa uye zvinodiwa zvekugadzirisa.
4. Tembiricha uye kumhanya kudzora:
-Tembiricha uye kutenderera kumhanya kwakakosha paramita inokanganisa kugadzirisa kwetwin screw extruder, uye inoda kurongeka uye kutonga.
-Kudzora kwekushisa kunofanirwa kugadziridzwa zvinoenderana neyakasiyana mbishi zvinhu uye kugadzirisa zvinodiwa. Tembiricha yakawandisa inogona kukonzeresa kukwirisa kana kupisa kwezvinhu zvakabikwa, zvichikanganisa kunaka kwechigadzirwa.
-Kudzora kwekutenderera kumhanya kunodawo kugadziridzwa zvine musoro zvichibva pane mbishi zvinhu uye kugadzirisa zvinodiwa. Yakakwira kana yakaderera kutenderera kumhanya inogona kukanganisa kugadzirisa maitiro uye mhando yechigadzirwa.
5. Huwandu hwezvinhu uye maitiro ekudzora:
-Kudzora kwehuwandu hwezvinhu hunoda kugadziridzwa zvinoenderana nezvinodiwa zvemidziyo uye maitiro ezvakagadzirwa. Kuwedzeredza vhoriyamu yemidziyo kunogona kukonzera kuvharika kwemidziyo, nepo yakawandisa yakaderera zvinhu vhoriyamu inogona kuderedza kushanda zvakanaka.
-Kudzora kwemaitiro kunoda kurongeka kwakarongeka kwekudya uye kuburitsa kutevedzana kwezvinhu zvakabikwa, kuve nechokwadi chekugovera yunifomu yezvinhu zvakabikwa uye kuburitswa kwakajairika kwekubuda, uye kudzivirira kuvhara uye kusanganisa zviitiko.
6. Kuchenesa uye utsanana:
-Paunenge uchishandisa twin screw extruder, kutarisisa kunofanirwa kubhadharwa kune hutsanana uye hutsanana manejimendi emidziyo, uye kugara kucheneswa kwemasara uye guruva mukati memidziyo kunofanirwa kuitwa kudzivirira kusvibiswa kwemuchinjikwa uye kukura kwebhakitiriya.
