Kuomesa michina chinhu chakakosha murabhoritari uye maindasitiri maapplication. Vacuum drying ovens uye general drying oveni zvese zvakajairika midziyo yekuomesa, asi inosiyana zvakanyanya. Ichi chinyorwa chichaenzanisa vacuum drying ovens uye general drying ovens zvakadzama maererano nemisimboti, mabasa, maapplication, zvakanakira, uye zvazvakaipira, kuitira kuti vaverengi vanzwisise zvirinani uye vasarudze michina yekuomesa inokodzera zvavanoda.
I. Nheyo Kuenzanisa
Vacuum drying oven chinhu chekuomesa chinoputika uye chinobvisa unyoro kubva kune zvinhu nekudziisa munzvimbo yakavharwa vacuum. Iyo yekushanda musimboti inonyanya kutsamira pane yakaderera kufashaira poindi yemvura pasi pevacuum mamiriro, achibvumira zvinhu kuti zviwane kuomeswa kwematembiricha. Iyi nzira yekuomesa inodzivirira iyo yakaipa mhedzisiro yekupisa kwakanyanya pane zvinhu uku uchivandudza kuomesa.
Ovheni yekuomesa, kune rumwe rutivi, inopisa mweya uye inoshandisa convection nemwaranzi yemhepo inopisa kuti ibude uye kubvisa hunyoro kubva kune zvinhu. Tembiricha iri mukati mehovhoni yekuomesa inowanzokwira, zvichiita kuti ive yakakodzera kuomesa zvinhu zvine tembiricha inoomesesa.
II. Basa Kuenzanisa
Vacuum drying ovens dzine mabasa akawanda, akadai sekuomesa-kutonhora kwakadzika, kukurumidza kuomesa, uye kusaomesa{1}oxidizing. Nekuda kwenzvimbo yakasarudzika yevacuum, maovheni ekuomesa vacuum anonyanya kukodzera kuomeswa zvinhu zvinonzwa oxidation, kunyungudika, kana kuparara nyore pakupisa kwakanyanya. Uye zvakare, vacuum yekuomesa oveni inogona kuderedza kurasikirwa kwemhando yezvinhu panguva yekuomeswa kune imwe nhanho uye kunatsiridza kuomeswa kwemhando.
General drying ovens anonyanya kushandiswa kuomesa zvinhu zvine tembiricha shoma inodiwa. Kupisa mukati mevheni kunogona kugadziridzwa sezvinodiwa, asi kazhinji kwakakwira, izvo zvinogona kukanganisa zvimwe zvinhu. Uyezve, oxidation inogona kuitika panguva yekuomesa, ichikanganisa kunaka kwezvinhu.
III. Kuenzanisa Kwekushandisa
Vacuum drying ovens vane hupamhi hwekushandisa mumaindasitiri emakemikari, emishonga, ezvekudya, uye zvemagetsi. Muindasitiri yemakemikari, vacuum yekuomesa oveni inogona kushandiswa kuomesa akasiyana organic solvents uye catalysts; muindasitiri yemishonga, inogona kushandiswa kuomesa mishonga mbishi zvinhu, zvepakati, uye zvigadzirwa zvakapedzwa; muindasitiri yezvokudya, zvinogona kushandiswa kuomesa michero, miriwo, uye nyama; uye muindasitiri yemagetsi, anogona kushandiswa kuomesa zvemagetsi zvikamu uye semiconductor zvinhu.
Maovheni ekuomesera anonyanya kushandiswa kuomesa zvinhu mumaindasitiri akadai sehuni, mapepa, uye machira. Nekuda kwekushisa kwakanyanya mukati mechoto, kushanda kwavo kune zvinhu kushoma, nekudaro huwandu hwavo hwekushandisa hwakatetepa.
IV. Kuenzanisa Zvakanakira uye Zvakaipa
Zvakanakira vacuum drying ovens zvinonyanya zvinosanganisira: kuomeswa kwakanyanya, kuwana mhedzisiro yekuomeswa munguva pfupi; kunaka kwekuomesa, kuchengetedza ruvara rwepakutanga, kunhuhwirira, uye kudya kwemidziyo; uye kushanda kwakafara, kwakakodzera kuomesa zvinhu zvakasiyana-siyana. Nekudaro, maoveni ekuomesa vacuum anewo zvimwe zvakaipira, senge mutengo wepamusoro wemidziyo, kushanda kwakaoma uye kugadzirisa, uye hunyanzvi hwepamusoro zvinodiwa kune vanoshanda.
Zvakanakira mahovhoni ekuomesa mahovhoni maumbirwo awo ari nyore, kushanda kuri nyore, uye kukwanirana ne-kugadzirwa kukuru. Zvisinei, oxidation inogona kuitika panguva yekuoma, inokanganisa kunaka kwezvinhu; panguva imwe chete, kupisa kwakanyanya mukati mevheni kunogona kukanganisa zvimwe zvinhu; uyezve, kuomeswa kwemahovhoni akaomeswa kwakadzikira, uye nguva yekuomesa yakati rebei.
V. Mhedziso
Muchidimbu, maovheni ekuomesa uye maovheni ekuomesa zvakazara anosiyana zvakanyanya mumusimboti, basa, kushandisa, uye zvakanakira nekuipira. Vacuum drying ovens, nemhoteredzo yadzo yevacuum yakasiyana uye -kupisa kwekushisa kwepasi, anoshandiswa zvakanyanya mumaindasitiri emakemikari, emishonga, uye ezvekudya; nepo mahovhoni ekuomesa, ane chimiro chakareruka uye kushanda kuri nyore, anoshandiswa zvakanyanya mumaindasitiri akadai sehuni, mapepa, uye machira. Paunenge uchisarudza midziyo yekuomesa, zvinhu zvakaita sezvimiro zvechigadzirwa, zvinodikanwa zvekuomesa, uye mutengo zvinofanirwa kutariswa zvakakwana kuti usarudze iyo yakanyatsokodzera michina kune zvaunoda.
