Ⅰ. Convection drying
Mukuomesa midziyo, iyo yakajairika mhando yemidziyo yekuomesa ndeye convection kupisa kupisa kuomesa. Semuyenzaniso,kupisa mhepo kuomesa, mhepo inopisa uye kubata kwezvinhu zvekuchinjana kwekupisa kuitira kuti unyoro uwedzere. Mhando dzakajairwa dzemidziyo yekuomesa mhepo ndeyekumisa mhepo, senge fluidized bed dryer, flash dryer, air dryer, spray dryer, ventilation dryer, flow dryer, air flow rotary dryer, zvinokuchidzira dryer, parallel flow dryers,rotary dryerzvichingoenda zvakadaro.
Mukushanda kwekushandisa, kune michina imwe chete inoshandiswa uye yakasanganiswa michina inoshandiswa. Air flow dryer, fluidized bed dryer, spray dryer, etc. vari kushandisa mhepo inopisa sesosi yekupisa, uye kuendesa zvinhu kunopedzwa uchiomesa, uye maomeseji akadaro anonyanya kuzivikanwa nekusavapo kwezvikamu zvekutapurirana.
Kuomesa poda, granule uye flake zvinhu, yakajairika kushandisa mhepo inopisa kana gasi kuyerera pamusoro pegranule, uye kuendesa kupisa kune izvo zvinhu kuburikidza nekuyerera kwemhepo kuti iputse mvura. Mupfunga wemvura wakabuda mumhepo unoenda zvakananga mumhepo uye wotorwa. Iyo yekuomesa midhiya inowanzoshandiswa mu convection drying system imhepo, inert gasi, yakananga gasi rinopisa kana superheated steam.
Iyo nzira inoita kuti mhepo inopisa ibatane zvakananga nezvinhu uye inobvisa hunyoro paunenge uchipisa. Chinokosha ndechekuvandudza nzvimbo yekubatana pakati pezvinhu uye nemhepo inopisa kudzivirira kupisa kwemhepo. Iyo tembiricha yemidziyo panguva yekuomeswa kweisokinetic yakada kufanana neyakanyorova tembiricha yegirobhu yemhepo inopisa, saka kushandiswa kwemhepo inopisa inopisa kunogonawo kuomesa zvinhu zvinopisa kupisa. Iyi nzira yekuomesa ine yakanyanya kuomeswa mwero uye yakaderera mutengo wemidziyo, asi kushanda kwemafuta kwakadzikira, inotevera ndiyo mamiriro ekutanga eakawanda convection drying michina:
(1) Ventilation dryer
Ita pamusoro pechivharo kana zvinhu zvave zvakagadziriswa chimiro kusangana nemhepo inopisa. Chiyero chekuomesa chakaderera, asi huwandu hwekushandisa hwakakura.
(2)Fluidized bed dryer
Rega mhepo inopisa ivhuvhute zvakaenzana kubva pasi pehupfu hwehupfu uye granular zvinhu uye uite kuti ienderere, kuitira kuti zvinhu zvive zvakasanganiswa zvakasimba uye zvakapararira. Mwero wekuomesa wakakwira.
(3) Airflow dryer
Iyi nzira inoita kuti hupfu hupararire mumhepo inopisa inopisa uye inoendesa zvinhu panguva yekuomesa. Iyi modhi ine nguva shoma yekuomesa uye yakakodzera kubata zvinhu muhuwandu hukuru. Kana zvinhu kupinda muomesi usati washandisa michina nzira kubvisa yakawanda mvura asati apinda mhepo dryer zvikuru mari.
(4) Spray dryer
Saka kuti mhinduro kana slurry zvinhu mune yakakwirira tembiricha inopisa mhepo atomization, madonhwe anodonha panguva imwe pakarepo kuomesa. Iyi nzira yekuomesa nguva ipfupi, yakakodzera kugadzirwa kwakawanda, yemishonga, punch, dhayi kuomeswa.
(5) Rotary cylinder dryer
Gadzira hupfu, block, slurry zvinhu kuburikidza nedhiramu rinotenderera rinosangana nemhepo inopisa. Iyi nzira yakakodzera kugadzirwa kwehuwandu. Mushure mekuomesa zvinhu zvedhaka zvinogona kuburitswa senge granular zvinhu, akawanda akakwira tembiricha anodzivirira mineral drying anoshandiswa nenzira iyi.
(6) flash dryer
Nyaya yacho inokurudzirwa nepamusoro-soro inotenderera inotenderera inokonzera, kuitira kuti iparadzirwe mukufamba kunotenderera kwemhepo yegesi panguva imwechete yekuoma. Kazhinji inoshanda pakuomeswa kwezvinhu zvepakati-vhoriyamu, zvinonyanya kushandiswa kuomesa paste zvinhu.
Ⅱ. Conduction drying
Conduction drying inochinjika zvakanyanya kune zvinyoro zvimedu, uye conduction yekuomesa michina ine yakanyanya kupisa kunyatsoshanda. Iyo evaporated mvura mhute inoburitswa ne vacuum kana kuburitswa nemhepo, inova ndiyo inotakura hunyoro, uye vacuum mashandiro anokurudzirwa kune kupisa-sensitive granular zvinhu. Mune conduction yekuomesa michina, paddle dryer inoshandiswa kuomesa paste zvinhu. Rotary dryer ane machubhu ekuyerera emukati zvave kugadzirwa, senge yekunyudza yakanyungudutswa mubhedha yekuomesa yekuomesa kupisa-sensitive mapolymers kana mafuta pellets, inongori chikamu chimwe chete muzvitatu chehukuru hweyakajairwa mubhedha wakaomeswa.
Vacuum drying inzira yekudzikira tembiricha uye yakaderera kuomeswa nekudziisa zvinhu pasi pevacuum mamiriro ekuita kuti hunyoro hupararire nechomukati, hunyunguruke mukati, sublimate, uye kubuda pamusoro. Iyo ine mabhenefiti eyakadzika kupisa tembiricha, yakanaka antioxidant performance, yunifomu chigadzirwa mwando wemukati, yepamusoro mhando uye kushandisa. Kuomesa vacuum kunodhura kushanda, uye kuomesa vacuum kunokurudzirwa chete kana zvinhu zvacho zvichifanira kuomeswa pasi petembiricha yakaderera kana kushomeka kweokisijeni, kana kuti painozodzikiswa nekuoma pasi pekudziya kwepakati uye tembiricha yakakwira. Kune imwe evaporation inoshanda, yakakwira tembiricha mashandiro anoshandiswa kuitira kuti gasi rekuyerera rideredzwe uye huwandu hwemidziyo hugone kudzikiswa. Kune yakaderera-tembiricha yekuomesa mashandiro, yakakodzera yakaderera-tembiricha tsvina kupisa kana solar muunganidzi anogona kusarudzwa senzvimbo yekupisa, asi huwandu hweiyo dryer yakakura.
Ⅲ. Combination drying
Uchishandisa nzira dzakasiyana dzekuomesa, dzakasiyana dzekuomesa musimboti musanganiswa, unogona kutamba masimba avo uye kugadzirisa kukanganisa kwavo kwemidziyo yekuomesa. Semuenzaniso, nzira yekuomesa yakananga uye nzira yekuomesa isina kunanga uye shandisa nzira yekuomesa isina kunanga kupa kuomesa ruzhinji rwekupisa kunodiwa. Nenzira iyi, chiyero chekuomeswa chinogona kuvandudzwa, uye nzira yakananga uye isina kunanga yekuomesesa uye yekuomesa michina ine diki midziyo vhoriyamu uye yakakwirira yekupisa inoshanda inogona kuwanikwa.
Yakasanganiswa yekuomesera michina inoshandiswawo zvakanyanya uye zvakanyanya, senge spray dryer uye vibration fluidized bed dryer musanganiswa, rake dryer uye vibration fluidized bed dryer musanganiswa, rotary kusanganisa dryer, conduction mixing dryer, air dryer uye fluidized bed dryer musanganiswa. Musanganiswa wechinangwa ndechekuwana hunyoro hwakaderera, senge single spray dryer inogona kuwanikwa 1% -3% hunyoro hwechigadzirwa, senge hunyoro hwe 0.3% kana pasi, tembiricha yekubuda inowanzodiwa kusvika 120 ℃ kana zvakanyanya, kurasikirwa kwesimba rekupisa kwakakura kwazvo. Saizvozvo, kana paine zvimwe zvinodiwa kuti hunyoro, hunyoro husingasviki 0.1%, tembiricha yekubuda inodiwa pamusoro pe130 ℃. Kuti uchengetedze simba rekupisa, mukugadzirwa kwekushandiswa kwakawanda kwe90 ℃ yekupedza tembiricha yespray dryer, kuitira kuti hunyoro hunosvika 2%, kudzoreredza kupisa kunogadzirwa ne60 ℃ mhepo inopisa inogona kushandiswa munhevedzano pakuomesa. iyo yakatwasuka fluidized mubhedha, kupera kwemwando kunogona kusvika 0.1% kana zvishoma, uye kupisa simba kunogona kuchengetedza 20%.
Mune zvimwe zviitiko, kana chigadzirwa chakaomeswa kana kugadziriswa, kupisa kwekunzwa kwechigadzirwa kunobudisa shanduko, kana maitiro echigadzirwa kuchinja. Zviripachena, muchiitiko ichi kushandiswa kwemaviri kana anopfuura maviri akasiyana mafomu ekuomesa midziyo kusanganiswa kwekuomeswa kwakanaka.
Zvadaro, ungasarudza sei maomesi akakodzera emidziyo yako? Kugamuchirwa kutaurirana!
