Ⅰ. Ukomiswa kwe-convection
Emishinini yokomisa, uhlobo oluvame kakhulu lwemishini yokomisa isomisi esidlulisa ukushisa. Ngokwesibonelo,umoya oshisayo omiswe, umoya oshisayo kanye nokuthintana kwezinto zokushintshanisa ukushisa ukuze kuhwamuke umswakama. Izinhlobo ezijwayelekile zemishini yokomisa i-convection yizinto zokomisa umoya, njengezomiso zombhede ezinamanzi, okomisa umbhede, okomisa umoya, okomisa umoya, okomisa umoya, okomisa umoya, okomisa ukugeleza, okomisa komoya okujikelezayo, okomisa okomisa, okomisa ukugeleza okufanayo,okomisa ama-rotarynjalo njalo.
Ekusetshenzisweni okusebenzayo, kunemishini eyodwa esetshenziswa kanye nemishini ehlanganisiwe esetshenziswa. Isomisi sokugeleza komoya, isomisi sombhede esiwuketshezi, isomisi sesifutho, njll. sisebenzisa umoya oshisayo njengomthombo wokushisa, futhi ukudluliselwa kwezinto kuyaqedwa ngenkathi zomiswa, futhi ezomisi ezinjalo zibonakala kakhulu ngokungabi bikho kwezingxenye zokudlulisela.
I-powder yokomisa, i-granule kanye ne-flake materials, indlela evamile ukusebenzisa umoya oshisayo noma ukugeleza kwegesi ebusweni be-granule, nokudlulisa ukushisa ezintweni ngokusebenzisa ukugeleza komoya ukuze kuhwamuke amanzi. Umhwamuko wamanzi ohwamukile uya ngqo emoyeni futhi uthathwe. Imidiya yokomisa evame ukusetshenziswa ohlelweni lokomisa i-convection umoya, igesi engasebenzi, igesi evuthayo eqondile noma isitimu esishisa kakhulu.
Indlela yenza umoya oshisayo uthintane ngokuqondile nezinto futhi isuse umswakama ngenkathi ishisa. Isihluthulelo siwukuthuthukisa indawo yokuxhumana phakathi kwezinto kanye nomoya oshisayo ukuvimbela ukuphambuka komoya oshisayo. Izinga lokushisa lempahla ngesikhathi sokoma kwe-isokinetic licishe lifane nezinga lokushisa lebulb elimanzi lomoya oshisayo, ngakho-ke ukusetshenziswa komoya oshisayo osezingeni eliphezulu nakho kungamisa izinto ezingezwani nokushisa. Le ndlela yokomisa inezinga eliphezulu lokumisa kanye nezindleko eziphansi zemishini, kodwa ukusebenza kahle kokushisa kuphansi, okulandelayo yisimo esiyisisekelo semishini yokumisa i-convection eminingana:
(1)Isomisi sokungenisa umoya
Yenza ingaphezulu lebhulokhi noma impahla eseyishintshile ithintane nomoya oshisayo. Izinga lokumisa liphansi, kodwa ububanzi bohlelo lokusebenza lubanzi.
(2)Isomisi sombhede esiwuketshezi
Vumela umoya oshisayo uqhume ngokulinganayo kusukela phansi kwesendlalelo se-powder kanye nezinto ze-granular futhi uzenze zigeleze, ukuze izinto zizohlanganiswa ngamandla futhi zihlakazwe. Izinga lokomisa liphezulu.
(3)Isomisi somoya
Le ndlela yenza impushana ihlakazeke ekushiseni okuphezulu emoyeni oshisayo futhi idlulisele impahla ngenkathi yomiswa. Lo modeli unesikhathi esifushane sokumisa futhi ufanelekile ukuphatha izinto ngobuningi. Uma izinto zingene ekomisweni ngaphambi kokusebenzisa izindlela zemishini zokususa amanzi amaningi ngaphambi kokungena emshinini wokomisa umoya ziyonga kakhulu.
(4) Umshini wokomisa isifutho
Ukuze ikhambi noma izinto eziludaka izinga lokushisa eliphezulu hot air atomization, amaconsi falling ngesikhathi esifanayo omiswe kweso. Le ndlela yokomisa isikhathi sifushane, ilungele ukukhiqizwa ngobuningi, kwezemithi, i-punch, ukomisa udayi.
(5) Isomisi se-cylinder ejikelezayo
Yenza impushana, ibhulokhi, izinto eziludaka ngokusebenzisa isigubhu esijikelezayo esithinta umoya oshisayo. Le ndlela ilungele ukukhiqizwa ngobuningi. Ngemuva kokumisa izinto zodaka zingakhishwa njengezinto ze-granular, ukomiswa kwamaminerali amaningi okushisa aphezulu asetshenziswa ngale ndlela.
(6) i-flash dryer
Indaba ishukunyiswa yi-high-speed ejikelezayo ejikelezayo, ukuze ihlakazwe ekuhambeni okujikelezayo komfudlana wegesi ngesikhathi esifanayo ukomisa. Ngokujwayelekile kusebenza ekomisweni kwezinto ezinomthamo omaphakathi, ezisetshenziselwa kakhulu ukomisa izinto zokunamathisela.
Ⅱ. Ukomiswa kokwenziwa
I-conduction drying ivumelana kakhulu nezinhlayiya ezimanzi, futhi imishini yokomisa i-conduction inokusebenza kahle okuphezulu kokushisa. Umhwamuko wamanzi ohwamukile ukhishwa nge-vacuum noma ukhishwe ukugeleza komoya, okuwumthwalo oyinhloko womswakamo, futhi ukusebenza kwe-vacuum kunconyelwa ezintweni ezibunjiwe ezizwela ukushisa. Emishinini yokomisa, i-paddle dryer isetshenziselwa ukomisa izinto zokunamathisela. Izomiso ezijikelezayo ezinamashubhu okugeleza kwangaphakathi manje seziklanyelwe, njengesomiso sombhede esicwiliswa emanzini sokumisa ama-polymer angezwani nokushisa noma ama-pellets amafutha, okuyingxenye eyodwa kwezintathu kuphela yosayizi wesomiso sombhede esimanzi.
Ukomisa nge-vacuum inqubo yokushisa okuphansi nokomisa komfutho ophansi ngokufudumeza impahla ngaphansi kwezimo ze-vacuum ukuze wenze umswakama usabalele ngaphakathi, uhwamuke ngaphakathi, u-sublimate, futhi uhwamuke phezulu. Inezinzuzo zokushisa okuphansi kokushisa, ukusebenza okuhle kwe-antioxidant, okuqukethwe komswakama womkhiqizo ofanayo, ikhwalithi ephezulu kanye nokusetshenziswa. Ukomisa i-vacuum kuyabiza ukusebenza, futhi ukomiswa kwe-vacuum kunconywa kuphela lapho impahla kufanele yomiswe ngaphansi kwezinga lokushisa eliphansi noma ukuntuleka komoya-mpilo, noma lapho izokonakala ngokumiswa ngaphansi kokushisa okuphakathi nendawo nokushisa okuphezulu. Ukuze kusebenze kahle ukuhwamuka okuthile, ukusebenza kokushisa okuphezulu kusetshenziswa ukuze izinga lokugeleza kwegesi lincishiswe futhi umthamo wemishini ungancishiswa. Ngomsebenzi wokumisa izinga lokushisa eliphansi, ukushisa kwemfucuza okunezinga eliphansi lokushisa okufanelekile noma umqoqi welanga kungakhethwa njengomthombo wokushisa, kodwa umthamo wesomiso mkhulu kakhulu.
Ⅲ. Ukomisa inhlanganisela
Ngokusebenzisa izindlela zokomisa ezihlukene, inhlanganisela yezimiso zokomisa ehlukene, ingadlala amandla azo futhi ilungise ukushiyeka kwayo kwemishini yokomisa. Isibonelo, indlela yokomisa eqondile kanye nendlela yokomisa engaqondile futhi usebenzise indlela yokomisa engaqondile ukuze unikeze ukomisa okuningi kokushisa okudingekayo. Ngale ndlela, izinga lokumisa lingathuthukiswa, futhi indlela yokomisa eqondile nengaqondile kanye nemishini yokumisa enomthamo omncane wemishini kanye nokusebenza kahle okuphezulu kokushisa kungatholakala.
Imishini yokomisa ehlanganisiwe ibuye isetshenziswe kakhulu nangokwengeziwe, njengenhlanganisela yokomisa umbhede onyakaziswayo kanye nenhlanganisela yokomisa umbhede onyakaziswayo, umshini wokomisa umbhede onyakaziswayo kanye nenhlanganisela yokomisa umbhede onyakaziswayo, umshini wokomisa ojikelezayo, umshini wokomisa i-conductive, umshini wokomisa umoya kanye nenhlanganisela yokomisa umbhede owuketshezi. Inhlanganisela inhloso ukuthola umswakama ophansi, ezifana single spray dryer ingatholakala 1% -3% okuqukethwe umswakama umkhiqizo, ezifana nokuqukethwe umswakama 0.3% noma ngaphansi, izinga lokushisa qeda ngokuvamile kudingeka 120 ℃ noma ngaphezulu, ukulahlekelwa amandla okushisa kukhulu kakhulu. Ngokufanayo, uma kunezinye izidingo zomswakama, umswakama ongaphansi kuka-0.1%, izinga lokushisa lokukhipha umoya liyadingeka ngaphezu kuka-130 ℃. Ukuze ulondoloze amandla ashisayo, ekuklanyeni ukusetshenziswa okujwayelekile kwezinga lokushisa elingu-90 ℃ lokuqeda ukushisa kwe-spray dryer, ukuze umswakama ube ngu-2%, ukubuyiswa kokushisa okukhiqizwe umoya oshisayo ongu-60 ℃ kungasetshenziswa ochungechungeni ukuze omiswe umbhede ovundlile owenziwe ngamanzi, ukuphela komswakama kungafinyelela ku-0.1% noma ngaphansi, futhi amandla ashisayo angasindisa ama-20%.
Kwezinye izimo, lapho umkhiqizo usomisiwe noma ucutshungulwa, ukuzwela kokushisa komkhiqizo kukhiqiza ushintsho, noma izici zomkhiqizo zishintsha. Ngokusobala, kulokhu ukusetshenziswa kwezinhlobo ezimbili noma ezingaphezu kwezimbili ezihlukene zokuhlanganiswa kwemishini yokomisa kuhle.
Khona-ke, ungakhetha kanjani ama-dryer afanelekile wezinto zakho zokwakha? Siyakwamukela ukuxhumana!
