Ⅰ. Ukuxhuma ukoma
Emishini yokumisa, uhlobo olujwayelekile lwemishini yokumisa ingusomisi wokudlulisa ukushisa okushintshiwe. Ngokwesibonelo,ukoma komoya okushisayo, umoya oshisayo kanye nokuxhumana okubonakalayo kokushintshana kokushisa ukuze ukhiphe umswakama. Common types of convection drying equipment are air suspension dryers, such as fluidized bed dryers, flash dryers, air dryers, spray dryers, ventilation dryers, flow dryers, air flow rotary dryers, stirring dryers, parallel flow dryers,Ama-Rotary Dortarsnjalo njalo.
Ngohlelo lokusebenza olusebenzayo, kunemishini eyodwa esetshenzisiwe nemishini ehlanganisiwe esetshenzisiwe. I-Air Flow Dryer, owomile we-Flue Flued, i-Spray Dryer, njll. Basebenzisa umoya oshisayo njengomthombo wokushisa, futhi ukudluliswa kwezinto kuqediwe ngenkathi ukomisa, futhi amasomi anjalo abonakala ikakhulukazi ngokungabikho kwezingxenye zokuhambisa.
Ukomisa i-powder, izinto zokwakha i-granule kanye ne-flake, indlela ejwayelekile ukusebenzisa umoya oshisayo noma igesi ebusweni be-granule, bese udlulisela ukushisa entweni nge-airflow ukuhwamuka namanzi. Umphunga wamanzi ohanjiswa uhamba ngqo emoyeni futhi uyasuswa. Imithombo yokomisa esetshenziswa kakhulu ohlelweni lokuxhumanisa okomisa luyindiza, i-inert gesi, igesi eqondile yokuhlanganisa noma umusi oshubile.
Le ndlela yenza umoya oshisayo uxhumane ngqo nokuqukethwe futhi ususe umswakama ngenkathi ushisa. Isihluthulelo ukuthuthukisa indawo yokuxhumana phakathi kwezinto ezibonakalayo kanye nomoya oshisayo ukuvikela ukuqunjelwa komoya okushisayo. Ukushisa okubonakalayo ngesikhathi sokumiswa kwe-isokinetic kucishe kufane nokushisa kwe-bulb okushisayo komoya oshisayo, ngakho-ke ukusetshenziswa komoya oshisayo okushisa kakhulu kungaveza izinto ezibucayi zokushisa. Le ndlela yokomisa inezinga eliphakeme lokumisa kanye nezindleko eziphansi zemishini, kepha ukusebenza kahle okushisayo kuphansi, okulandelayo kuyisisekelo esiyisisekelo semishini yokuxhumanisa eminingana:
(1) owomisa umoya omncane
Yenza ingaphezulu lebhlokhi noma okuqukethwe okuye kwaba yilona lesimo sokuxhumana ngomoya oshisayo. Izinga lokumisa liphansi, kepha uhla lohlelo lubanzi.
(2) Dlulisa umbhede owomile
Vumela umoya oshisayo uvunguze ngokulinganayo kusuka ezansi kwesendlalelo se-powder nezinto zokwakha ama-granular futhi uzenze kuphumelele, ukuze izinto zokwakha zihlangane ngamandla futhi zihlakazeke. Izinga lokumisa liphezulu.
(3) owomile we-airflow
Le ndlela yenza i-powder ehlakazeke emoyeni okushisa kakhulu okushisayo futhi idlulisela lokho okuqukethwe ngenkathi yomiswa. Le modeli inesikhathi sokumisa esifushane futhi ilungele ukusingatha izinto ngobuningi. Uma impahla iye esomile ngaphambi kokusebenzisa izindlela zemishini ukususa iningi lamanzi ngaphambi kokungena komoya komoya kungokomnotho ngokwengeziwe.
(4) Spray Dryer
Ukuze isixazululo noma izinto ezibucayi ezishifuni eziphakeme zokushisa okushisayo air atomization, amaconsi awela ngasikhathi sinye somiswa ngaso leso sikhathi. Le ndlela yokumisa isikhathi imfushane, ilungele ukukhiqizwa kwabantu abaningi, kumakhemikhali, punch, ukomisa udayi.
(5) I-Rotary Cylinder Drser
Yenza i-powder, ibhulokhi, izinto ezibucayi ngokusebenzisa umoya ojikelezayo wesigubhu. Le ndlela ilungele ukukhiqizwa kwesisindo. Ngemuva kokumisa impahla kadaka kungadedelwa njengezinto ze-granular, kusetshenziswa amaminerali amaningi okushisa amaminerali amelana nale ndlela.
(6) I-Flash Dryer
Okuqukethwe kushukunyiswa i-speak-speed eshukumisayo evuthayo evuthayo, ukuze ihlakazeke ekuhambeni okujikelezayo kokusakazwa kwegesi ngasikhathi sinye somiswa. Ngokuvamile kusebenza ekomisweni kwezinto eziphakathi nendawo, ezisetshenziselwa kakhulu ukumisa izinto zokwakha.
Ⅱ. Ukoma ukumboza
Ukomisa ukukhishwa kuvumelana kakhulu nezinhlayiya ezinomswakama, kanye nemishini yokumisa yokwakha inokusebenza kahle okushisayo. Umphunga wamanzi ohanjiswa ukhishwe nge-vacuum noma ekhishwe yi-airflow, okuyinkampani ephathina ephambili yomswakama, futhi ukusebenza kwe-vacuum kunconyelwe izinto ezibucayi zokushisa. Emishini yokumisa yokuthobela, i-Paddle Dryer isetshenziselwa ukumisa izinto zokwelula. Ama-rotary owomisa amashubhu wokugeleza kwangaphakathi aseklanyelwe, njengokucwilisa umhlwenga umbhede owomile wokomisa ama-polymers abucayi bokushisa noma ama-pellets amafutha, okungukuphela kwengxenye eyodwa kwezintathu yosayizi ojwayelekile we-flualized fluidalized dryer.
Ukomisa we-Vacuum inqubo yokushisa okuphansi kanye nengcindezi ephansi yokomisa ngokushisa impahla ngaphansi kwezimo ze-vacuum ukwenza umswakama usebenzise umswakama ngaphakathi, okuvulekeleni ngaphakathi, futhi uvele ebusweni. Inezinzuzo zokushisa okuphansi kokushisa, ukusebenza okuhle kwe-antioxidant, umfaniswano womkhiqizo womswakama, ikhwalithi ephezulu kanye nesicelo. Ukusoma kwe-Vacuum kuyabiza kakhulu ukusebenza, futhi ukomisa i-vacuum kunconywa kuphela lapho okuqukethwe kufanele komiswe ngaphansi kokushisa okuphansi noma ukuntuleka komoya-mpilo, noma lapho kuzokondlakala ngokomiswa ngaphansi kokushisa okuphakathi nokushisa okuphezulu. Ngokusebenza kahle kokuhwamuka okuthile, ukusebenza okuphezulu kokushisa kusetshenziswa ukuze kuncishiswe izinga lokugeleza kwegesi futhi umthamo wemishini ungancishiswa. Ngokusebenza kokushisa okushisa okuphansi, ukushisa okushisa okuphansi okuphansi noma umqoqi welanga kungakhethwa njengomthombo wokushisa, kepha umthamo wesomisi ukhulu.
Ⅲ. Inhlanganisela yokomiswa
Kusetshenziswa izindlela ezahlukene zokumisa, inhlanganisela yomigomo ehlukile, ingadlala amakhono abo futhi ikwenzele ukushiyeka kwabo kwemishini yokomisa. Isibonelo, indlela eqondile yokumisa kanye nendlela yokumisa engaqondile futhi usebenzise indlela yokumisa engaqondile ukuhlinzeka ukomisa iningi lokushisa okudingekayo. Ngale ndlela, izinga lokumisa lingathuthukiswa, kanye nendlela yokumisa eqondile nengaqondile yokomisa nemishini yokomisa ngevolumu encane yemishini nokusebenza kahle okushisayo okuphezulu kungatholakala.
Imishini yokumisa ehlanganisiwe isetshenziswa futhi ngaphezulu, njenge-Spray Dryer Fluemer Fluer Dryer inhlanganisela, inhlanganisela yokuxuba umbhede ephefumule kanye ne-dryer yokuxuba uketshezi, inhlanganisela yokomisa yomoya evulekile, inhlanganisela yombhede yokomisa uketshezi kanye nenhlanganisela ye-flued dryer ye-flued. Inhlanganisela yenhloso ukuthola umswakama ophansi, njenge-sorsor eyodwa yesipifaza ingatholakala 1% -3% umswakama wokuqukethwe komkhiqizo, njengokuqukethwe komswakama okungu-0.3% noma ngaphezulu, ukulahleka kwamandla okushisa kukhulu kakhulu. Ngokufanayo, uma kunezidingo ezengeziwe zomswakama, okuqukethwe umswakama ongaphansi kwe-0,1%, izinga lokushisa eliphumayo liyadingeka ngaphezulu kwe-130 ℃. Ukuze usindise amandla afudumele, ekwakhiweni kokusetshenziswa okujwayelekile kwamazinga okushisa okushisa angama-90 ℃ akhishwe ngo-20
Kwezinye izimo, lapho umkhiqizo womile noma ucutshungulwa, ukuzwela kokushisa komkhiqizo kukhiqiza ushintsho, noma izici zoshintsho lomkhiqizo. Ngokusobala, kulokhu ukusetshenziswa kwezindlela ezimbili noma ezingaphezu kwezimbili ezahlukahlukene zokuhlanganiswa kwemishini yomiswa komiswa kuhle.
Ngemuva kwalokho, ungayikhetha kanjani ukomisa ofanele kwezinto zakho zokwakha? Uyemukelwa ukuxhumana!
