Single screw extruder: yoyenera kupangira chinthu chimodzi komanso ziweto wamba ndi nkhuku zodyera limodzi.
Twin screw extruder: yomwe imagwiritsidwa ntchito popanga zakudya zam'madzi ndi zoweta zamtengo wapatali, monga eel, kamba, ndi chakudya cha nsomba zazing'ono, chifukwa mitengo yazinthuzi zomwe zimagulitsidwa pamsika ndizokwanira kubweza mtengo wopangira zinthu pogwiritsa ntchito. teknoloji yamapasa awiri; Kuphatikiza apo, chakudya cham'madzi chapadera, monga chakudya cham'madzi (chokhala ndi m'mimba mwake 0.8 ~ 1.5mm), chakudya chamafuta ambiri cham'madzi, ndi chakudya chokhala ndi voliyumu yaying'ono yopangira koma chikusintha mosalekeza, chimafunikanso kupangidwa pogwiritsa ntchito mapasa wononga extruder. .
Ziyenera kufotokozedwa kuti kusiyana kumeneku sikuli kotsimikizika. Mwachitsanzo, tikuganiza kuti tigwiritse ntchito zomangira ziwiri kuti apange chakudya cham'madzi, koma tsopano makampani ambiri amagwiritsa ntchito zomangira imodzi kuti apange chakudya cham'madzi. Pali kusiyana pakugwiritsa ntchito ziwirizi pazakudya zam'madzi. Mwachidule, poyerekeza ndi screw single, wononga pawiri ali ndi ubwino zotsatirazi:
① Kusinthika kwa zinthu zopangira ndikukula, komwe kumatha kutengera kukhathamiritsa kwamphamvu kwambiri, kukhuthala pang'ono, mafuta ochulukirapo, chinyezi chambiri kapena mamasukidwe, mafuta, zonyowa kwambiri, ndi zida zina zomwe zimatha kutsetsereka mu screw imodzi (SSE) .
② Pali zoletsa zochepa pa kukula kwa tinthu tating'onoting'ono, zomwe zimatha kutengera kusinthidwa kwa zinthu zopangira kuchokera ku ufa wang'ono kupita ku tinthu tating'onoting'ono tating'onoting'ono komanso phula limodzi lopangira zida zokhala ndi tinthu tosiyanasiyana.
③ Zomwe zimatuluka mkati mwa mbiya zimakhala zofananira, ndipo nthunzi, madzi, ndi zina zotere zitha kuwonjezeredwa kuti mukwaniritse zomwe mukufuna.
④ Ubwino wamkati ndi wakunja wa chinthucho ndi wabwinoko, womwe ungathe kukhala wabwino kwambiri wofanana ndi kupanga mamolekyu azinthuzo molingana. Pamwamba ndi yosalala pa ndondomeko extrusion. Tinthu tating'onoting'ono tating'onoting'ono timakhala ndi zofanana kwambiri komanso zofanana.
⑤ Kucha ndi homogenization kumakhala bwino, nthawi zambiri kumakhala ndi digiri ya wowuma yopitilira 95%, yomwe imathandizira kuti chakudya cham'madzi chokonzedwa kuti chisasunthike m'madzi, kupewa kutaya kwa michere yazakudya, komanso kukhala kosavuta kugaya ndi kuyamwa.
⑥ Zokolola zapamwamba pansi pa mphamvu zofanana. Good kusanganikirana ntchito chimathandiza yake homogenization kutentha analandira ndi zakuthupi, Iyamba Kuthamanga digiri kusasitsa zinthu, amachepetsa kusinthasintha kwa kutentha zinthu, ndi bwino linanena bungwe extruded mankhwala.
⑦ Kusiyanasiyana kwazinthu komanso kusinthasintha kwake ndikwambiri, ndipo imatha kukonza chakudya cham'madzi pang'ono, mafuta ochulukirapo, chinyezi chambiri, zomatira kwambiri, mitundu ingapo, masangweji, ndi zinthu zowoneka bwino.
⑧ Ntchitoyi ndiyosavuta, ndipo liwiro la spindle limatha kusinthidwa malinga ndi zosowa zazomwe zakonzedwa. Chifukwa chodzitchinjiriza, kuyeretsa ndikosavuta kwambiri, ndipo palibe chifukwa chosokoneza zida pambuyo pokonza.
⑨ Ziwalo zomwe zili pachiwopsezo zimavala zochepa. Lingaliro lolakwika lodziwika bwino ndiloti screw imodzi imakhala yochepa kwambiri. M'malo mwake, pamayendedwe amapasa wononga extrusion, chifukwa cha kukhazikika kwa zinthu zoyendera ndi mawonekedwe amtundu wa zinthu, kuvala kwa zinthu pa screw ndi malaya amkati a mbiya ndizocheperako kuposa screw imodzi. Ngakhale kuchuluka kwa zomangira ndi seti imodzi yowonjezereka, mtengo wazowonjezera udakali wotsika kuposa wa screw imodzi.
⑩ Mtengo wopangira ndi wotsika. Chifukwa cha kukhazikika kwa magwiridwe antchito amtundu wa screw model, pali ndalama zoyambira zoyambira, kuchepa kwa madzi ndi gasi, kutsika mtengo kwa ogwira ntchito, kutentha kwapang'onopang'ono, zokolola zambiri, komanso zisonyezo zamphamvu zamagetsi pakukonza chakudya. Kuphatikiza apo, mtengo wazinthu zowonjezera ndi wotsika, ndipo mtengo womaliza wopanga udakali wotsika kwambiri poyerekeza ndi screw imodzi.
Ndi chifukwa cha ubwino wambiri wa wononga mapasa kuyerekeza ndi wononga imodzi popanga chakudya cham'madzi chomwe timalimbikitsa kuti kusankha kwa screw extruder kukhale patsogolo pamene zinthu ziloleza m'mbali zonse.
Izi ndizomwe muyenera kusamala mukamagwiritsa ntchito mapasa screw extruder:
1. Chitetezo pantchito:
-Musanayambe kugwiritsa ntchito mapasa wononga extruder, m'pofunika kudziwa njira ntchito zipangizo, kusamala chitetezo, ndi kugwiritsa ntchito zipangizo shutdown mwadzidzidzi.
-Ogwira ntchito akuyenera kuvala zida zodzitetezera zomwe zimayenderana kuti apewe ngozi ndi kuvulala komwe kungachitike panthawi yogwira ntchito.
-Kuonetsetsa chitetezo cha malo ogwirira ntchito mozungulira zida ndikupewa ngozi monga kutsetsereka ndi kugundana.
2. Kukonza zida:
-Nthawi zonse sungani ndi kusamalira mapasa opangira ma screw extruder, kuphatikiza kuyeretsa, kuthira mafuta, kumangirira mabawuti, ndi zina. Onetsetsani kuti zida zikuyenda bwino.
-Yang'anani nthawi zonse zida zomwe zimavalidwa mosavuta monga zomangira, zochapira, ndi zomangira, ndikuzisintha munthawi yake kuti zida ziwoneke bwino.
-Kupanga mapulani ofananirako potengera kuchuluka kwa zida zomwe zimagwiritsidwa ntchito komanso malo ogwirira ntchito kuti zitsimikizire kuti zidazo zikugwira ntchito kwanthawi yayitali.
3. Kusintha kwazinthu zopangira:
-Makina opukutira a Twin ali ndi zofunika kwambiri pazida zopangira, ndipo zida zosiyanasiyana zimafunikira magawo osiyanasiyana opangira zinthu komanso njira zogwirira ntchito.
-Posankha zida, m'pofunika kuwonetsetsa kuti chitsanzo ndi ndondomeko ya zipangizozi ndizoyenera kugwiritsira ntchito zipangizo zamakono zogwiritsira ntchito potengera maonekedwe a zipangizo ndi zofunikira zopangira.
4. Kutentha ndi liwiro:
-Kutentha ndi liwiro lozungulira ndi magawo ofunikira omwe amakhudza kusinthika kwa mapasa wononga extruder, ndipo amafunikira kusintha koyenera ndi kuwongolera.
-Kuwongolera kutentha kuyenera kusinthidwa malinga ndi zida zosiyanasiyana komanso zofunikira pakukonza. Kutentha kwambiri kungayambitse kukhwima kwambiri kapena kuyaka kwa zipangizo zomwe zingawononge khalidwe lazogulitsa.
-Kuwongolera liwiro lozungulira kumafunikanso kusinthidwa molingana ndi zida zopangira komanso zofunikira pakukonza. Kuthamanga kwambiri kapena kutsika kozungulira kungakhudze momwe ntchitoyo imagwirira ntchito komanso mtundu wazinthu.
5. Kuchuluka kwazinthu ndi kayendetsedwe ka kayendetsedwe kake:
-Kuwongolera kuchuluka kwa zinthu kumafunika kusinthidwa malinga ndi momwe zida zimakhalira komanso mawonekedwe azinthu zopangira. Kuchulukirachulukira kwazinthu kungayambitse kutsekeka kwa zida, pomwe kutsika kwambiri kwazinthu kumatha kuchepetsa kukonza bwino.
-Kuwongolera ndondomekoyi kumafuna dongosolo loyenera la kudyetsa ndi kutulutsa kwazinthu zopangira, kuonetsetsa kugawidwa kwa yunifolomu ya zopangira ndi kutulutsa kwachibadwa, ndikupewa kutsekeka ndi kusakaniza zochitika.
6. Kuyeretsa ndi ukhondo:
-Pogwiritsa ntchito mapasa wononga extruder, chidwi chiyenera kuperekedwa ku ukhondo ndi kasamalidwe kaukhondo wa zida, ndi kuyeretsa nthawi zonse zotsalira ndi fumbi mkati mwa zipangizo ayenera kuchitidwa kupewa kuipitsidwa mtanda ndi kukula bakiteriya.
