Umahluko phakathi kwesikrufu esinye kunye nesikhupheli sesikrufu esiphindwe kabini

I-screw extruder enye: ifanelekile kwi-single material kunye nokutya okudibeneyo kwemfuyo kunye neenkukhu ngokubanzi.

I-extruder ye-twin screw: isetyenziswa ngokubanzi ekuveliseni ukutya okunexabiso eliphezulu kwamanzi kunye nezilwanyana zasekhaya, okufana ne-eel, i-turtle, kunye nokutya kweentlanzi ezincinci, kuba amaxabiso ezi mveliso zithengiswa kwimarike anele ukuhlawula iindleko zokuvelisa iimveliso kusetyenziswa ubuchwepheshe be-twin screw; Ukongeza, ukutya okukhethekileyo kwamanzi, okufana nokutya kwe-particulate emanzini (okunobubanzi obuyi-0.8 ~ 1.5mm), ukutya okunamafutha amaninzi emanzini, kunye nokutya okunomthamo omncinci wemveliso kodwa ifomula etshintsha rhoqo, kufuneka kuveliswe kusetyenziswa i-twin screw extruder.

Kufuneka kucaciswe ukuba umahluko ongentla awuqinisekanga. Umzekelo, sicebisa ukusebenzisa izikrufu ezimbini ukuvelisa ukutya kwasemanzini, kodwa ngoku iinkampani ezininzi zisebenzisa izikrufu esinye ukuvelisa ukutya kwasemanzini. Kukho umahluko ekusebenziseni ezi zimbini ukutya kwasemanzini. Ngamafutshane, xa kuthelekiswa nesikrufu esinye, isikrufu esiphindwe kabini sinezibonelelo ezilandelayo:

① Ukuguquguquka kwezinto ezikrwada kubanzi, nto leyo enokulungelelanisa ukucutshungulwa kwe-viscosity ephezulu, i-viscosity ephantsi, umxholo weoyile ophezulu, ukufuma okuphezulu okanye i-viscosity, izinto ezikrwada ezinamafutha, ezimanzi kakhulu, kunye nezinye izinto ezinokutyibilika kwi-screw enye (SSE).

② Kukho imiqathango embalwa ngobukhulu bamasuntswana ezinto ezikrwada, ezinokuziqhelanisa nokucutshungulwa kwezinto ezikrwada ukusuka kumgubo omncinci ukuya kumasuntswana empuphu erhabaxa kunye nokucutshungulwa kwesikrufu esinye sezinto ezinobukhulu bamasuntswana angaphandle koluhlu oluthile.

③ Ukuhamba kwezinto ngaphakathi kwibhereli kuyafana ngakumbi, kwaye umphunga, amanzi, njl. zingongezwa ukuze kufezekiswe isiphumo esifunekayo semveliso.

④ Umgangatho wangaphakathi nowangaphandle wemveliso ungcono, nto leyo enokufikelela kwimeko entle kakhulu efanayo kwaye yenze ulwakhiwo lweemolekyuli zezinto lulungelelaniswe ngokulinganayo. Umphezulu uthambile ngexesha lenkqubo yokukhupha. Amasuntswana emveliso anobunye obuphezulu kunye nobunye obuhle.

⑤ Isiphumo sokuvuthwa kunye nokuhlanganiswa kwe-homogenization singcono, ngesiqhelo xa i-starch ivuthwa ingaphezulu kwe-95%, nto leyo evumela ukutya kwasemanzini okucutshungulwayo ukuba kuhlale kuzinzile emanzini, kuthintele ukulahleka kwezondlo zemveliso, kwaye kube lula ukugaywa nokufunxwa.

⑥ Isivuno esiphezulu xa siphantsi kwamandla alinganayo. Ukusebenza kakuhle kokuxuba kwenza ukuba ubushushu obufunyenweyo bube semgangathweni ngexesha elifanelekileyo, kukhawulezise izinga lokuvuthwa kwezinto, kunciphisa ukuguquguquka kobushushu bezinto, kwaye kuphucula imveliso ekhutshweyo.

⑦ Ukwahluka kwemveliso kunye nokuguquguquka kwayo kubanzi, kwaye inokucubungula ukutya okuncinci kwamanzi, ifomula ephezulu yeoyile, umxholo ophezulu wokufuma, iimveliso ezinamathelayo kakhulu, kunye nemibala emininzi, uhlobo lwesandwich, kunye neemveliso ezimile ngokukodwa.

⑧ Ukusebenza kwenkqubo kulula ngakumbi, kwaye isantya se-spindle sinokulungiswa ngokweemfuno zemveliso ecutshungulwayo. Ngenxa yendlela yokuzicoca, ukucoca kulula kakhulu, kwaye akukho mfuneko yokuqhaqha izixhobo emva kokucubungula ngakunye.

⑨ Izinto ezisengozini ziguga kancinci. Ingcamango ephosakeleyo eqhelekileyo kukuba isikrufu esinye asigugi kangako. Enyanisweni, ngexesha lenkqubo yokukhupha izikrufu ezimbini, ngenxa yokuthuthwa kwezinto ezizinzileyo kunye neempawu zokuhamba kwezinto, ukuguga kwezinto ezikwiskrufu kunye nomkhono wangaphakathi webhereli kuncinci kunesikrufu esinye. Nangona inani lezikrufu lingaphezulu kwesinye iseti, ixabiso lezixhobo lisephantsi kunelesikrufu esinye.

⑩ Iindleko zemveliso ziphantsi. Ngenxa yokuzinza okuhle kokusebenza kwemodeli yezikrufu ezimbini, zimbalwa iindleko zokuqala, zincinci inkunkuma yamanzi negesi, zincinci iindleko zabasebenzi, ukusebenza kakuhle kokudlulisa ubushushu, isivuno esiphezulu, kunye neempawu zokukhupha umbane ophezulu kwinkqubo yokucubungula ukutya. Ukongeza, iindleko zezixhobo nazo ziphantsi, kwaye iindleko zokugqibela zemveliso zisephantsi kakhulu xa kuthelekiswa nesikrufu esinye.

Kungenxa yeenzuzo ezininzi zee-screw ezimbini xa kuthelekiswa ne-screw enye ekuveliseni ukutya kwasemanzini, ngoko ke sikhuthaza ukuba kukhethwe i-extruder ezimbini zee-screw xa iimeko zivuma kuzo zonke iinkalo.

Nazi iindlela zokukhusela ekufuneka zithathwe xa usebenzisa i-twin screw extruder:

1. Ukhuseleko lokusebenza:

-Ngaphambi kokuba usebenzise i-twin screw extruder, kubalulekile ukuba uqhelane neenkqubo zokusebenza kwezixhobo, amanyathelo okhuseleko, kunye nokusetyenziswa kwezixhobo zokuvala xa kukho ingxaki.

-Abaqhubi kufuneka banxibe izixhobo zokuzikhusela ezifanelekileyo ukuze baphephe iingozi kunye nokwenzakala okunokwenzeka ngexesha lokusebenza.

-Qinisekisa ukhuseleko lwendawo yokusebenza ejikeleze izixhobo kwaye uthintele iingozi ezifana nokutyibilika nokungqubana.

2. Ukugcinwa kwezixhobo:

-Qho gcina kwaye ulondoloze isixhobo sokukhupha izikrufu ezimbini rhoqo, kuquka ukucoca, ukuthambisa, ukuqinisa iibholiti, njl. Qinisekisa ukuba izixhobo zikwimeko entle yokusebenza.

-Hlola rhoqo izinto ezigugileyo ezinje ngezikrufu, iiwasher, kunye neendibano, uze uzitshintshe ngexesha elifanelekileyo ukuqinisekisa ukusebenza okuqhelekileyo kwezixhobo.

-Yila izicwangciso zolondolozo ezihambelanayo ngokusekelwe kwinani lokusetyenziswa kwezixhobo kunye nendawo yokusebenza ukuqinisekisa ukusebenza okuzinzileyo kwexesha elide kwezixhobo.

3. Ukuziqhelanisa nezinto ezikrwada:

-Oomatshini bokupusha izikrufu ezimbini baneemfuno eziphezulu zezinto ezikrwada, kwaye izinto ezahlukeneyo ezikrwada zinokufuna iiparameter ezahlukeneyo zenkqubo yokupusha kunye neendlela zokusebenza.

-Xa ukhetha izixhobo, kuyimfuneko ukuqinisekisa ukuba imodeli kunye neenkcukacha zezixhobo zifanelekile kwitekhnoloji yokucubungula efunekayo ngokusekelwe kwiimpawu zezinto eziluhlaza kunye neemfuno zokucubungula.

4. Ulawulo lobushushu kunye nesantya:

-Ubushushu kunye nesantya sokujikeleza zizinto ezibalulekileyo ezichaphazela isiphumo sokucubungula i-twin screw extruder, kwaye zifuna ukulungiswa nolawulo olufanelekileyo.

-Ulawulo lobushushu kufuneka luhlengahlengiswe ngokwezinto ezahlukeneyo eziluhlaza kunye neemfuno zokucubungula. Ubushushu obugqithisileyo bunokukhokelela ekuvuthweni okanye ekutshisweni kwezinto eziluhlaza kakhulu, nto leyo echaphazela umgangatho wemveliso.

-Ulawulo lwesantya sokujikeleza kufuneka luhlengahlengiswe ngokufanelekileyo ngokusekelwe kwizixhobo eziluhlaza kunye neemfuno zokucubungula. Isantya sokujikeleza esiphezulu okanye esiphantsi sinokuchaphazela isiphumo sokucubungula kunye nomgangatho wemveliso.

5. Ubungakanani bezinto kunye nolawulo lwenkqubo:

-Ulawulo lobungakanani bezinto ezisetyenziswayo kufuneka luhlengahlengiswe ngokweenkcukacha zezixhobo kunye neempawu zezinto ezisetyenziswayo. Ubuninzi bezinto ezisetyenziswayo bunokubangela ukuvaleka kwezixhobo, ngelixa ubunzima bezinto ezisetyenziswayo buphantsi kakhulu bunokunciphisa ukusebenza kakuhle kokusetyenzwa.

-Ulawulo lwenkqubo lufuna ulungiselelo olufanelekileyo lolandelelwano lokondla nokukhupha izinto ezikrwada, ukuqinisekisa ukusasazwa okufanayo kwezinto ezikrwada kunye nokukhutshwa okuqhelekileyo kwemveliso, kunye nokuthintela ukuvaleka kunye nokuxubana kweziganeko.

6. Ukucoca kunye nococeko:

-Xa usebenzisa i-twin screw extruder, kufuneka kuqwalaselwe ucoceko kunye nolawulo lococeko lwezixhobo, kwaye kufuneka kucocwe rhoqo iintsalela kunye nothuli ngaphakathi kwezixhobo ukuze kuthintelwe ukungcola okunqamlezileyo kunye nokukhula kweebhaktheriya.
