Chikafu chinowanzova nehunyoro hunosvika 30% kusvika 97%, uye kushandiswa kwekuomeswa nemicrowave kana microwave-kuwomeswa kwakawedzerwa kwechikafu kune tarisiro huru yekushandisa.
(1) Microwave inokurumidza kuomesa chikafu: Semuenzaniso, kushandisa microwave kudziyisa miriwo kusvika kune hunyoro huri pasi pe20% ("muriwo wakaomeswa") kunogona kuita zvakapetwa kagumi kupfuura nzira dzechinyakare. Iyi nzira haina kukodzera kuomesa muriwo chete asiwo yakakodzera kuomesa chikafu chegungwa-chinobva pakudya. Pasi pemaikorosikopu, nyama yemicrowave-muriwo wakaomeswa unoonekwa uri padyo kune wemuriwo mutsva pane imwe nzira yese kunze kwekuomeswa nechando-, asi nguva yekuomesa ipfupi pane kuomeswa nechando{7}}. Microwaves inogona zvakare kushandiswa pakuomeswa kwekupedzisira kwezvinhu zvakakangwa, kuchengetedza mafuta uye zvichikonzera chikafu chakareruka, chinonaka chine mafuta mashoma.
Kupisa mhepo kuomesa mukanyiwa kunotora maawa 5-8 kuti urege kuputika kana kuputika, nepo microwave kuomeswa kunongotora maawa 1-2 kuti iome kubva kune yekutanga mwando kusvika ku20%, nemhepo inopisa ichibvisa mwando, ichichengetedza 25% simba. Microwave drying inogonawo kuderedza kusvibiswa kwebhakitiriya; semuenzaniso, mumhepo inopisa yakasanganiswa uye microwave kuomeswa kwegariki, mhepo inopisa inoomesa mwando kubva pa80% kusvika 10% (yakanyorova hwaro), uye ipapo kuomeswa kwe microwave kunoderedza kusvika ku5%, zvichikonzera kuderedzwa kwe90% kwese mabhakitiriya uye 30% kuchengetedza simba.
Mumamiriro ezvinhu evacuum, ma microwave anogona kugadzira zvinhu zvinogona kukanganisa kana kudzikisira patembiricha iri pamusoro pe40 degrees (dzimwe nguva kunyange pa15 degree). Vacuum drying oveni dzinongoshandisa kupisa conduction, kazhinji pasina convective kudziyisa, zvichikonzera nguva refu yekuomesa. Zvigadzirwa zvakaomeswa uchishandisa microwave vacuum drying zvinosanganisira muchero concentrate, tii poda, enzymes, uye miriwo (howa, gariki, soya beans, nezvimwewo). Mutengo wekushandisa uri pakati pekupfapfaidza nekuomesa nechando-kuomesa. Mumasisitimu aya, chinhu chinowanzoita kunamira-sechinhu, chinowaridzwa pabhandi rekutakura, uye kupfuura nemugero wakanyatsogadzirwa (vacuum℃re133.3-2666 Pa), kugadzira furo rine zvinhu zvakanaka zvekudzorera mvura mumuviri.
