(2) inogara ichimhanya nguva: iyi ndiyo chiyero chekuomeswa ^ imwe nguva yenguva, iyo inoputika pamusoro pemvura, iyo yemukati inongokwana kuzadza, saka pamusoro pemvura firimu ichiri mukati, uye inochengetwa pakunyorova kwegirobhu tembiricha. .

I. Drying midziyo kuomesa mwero

1. nguva yeyuniti uye nzvimbo yechikwata, uremu hwezvinhu zvakarasika, inozivikanwa seyero yekuomesa.

2. Kuomesa nzira

(1) nguva yekutanga: nguva ipfupi, nekuti zvinhu zvichagadziriswa kumamiriro akafanana neanoomesa.

(2) inogara ichimhanya nguva: iyi ndiyo mwero wekuoma ^ nguva yakakura, iyo inoputika pamusoro pemvura, iyo yemukati inongokwana kuwedzera, saka pamusoro pemvura firimu ichiri mukati, uye inochengetedzwa pakunyorova kwegirobhu tembiricha.

(3) Kuderera kwenguva yenguva: panguva ino kubuda kwemvura, iyo yemukati haigoni kuzadzikiswa zvachose, saka firimu remvura repamusoro rakatanga kuputika, chiyero chekuoma chakatangawo kuderera, zvinhu panguva ino inonzi the critical point, mvura irimo panguva ino, inozivikanwa semvura yakaoma.

(4) Deceleration yechikamu chechipiri: chete dense zvinhu muchikamu ichi, nekuti mvura haisi nyore kuuya; asi iyo porous material haisi. Kubuda kwemvura munguva yekutanga kunowanzoitwa pamusoro, uye firimu remvura riri pamusoro rakapera zvachose munguva yechipiri, saka mvura inopararira kumusoro nenzira yemhute yemvura.

II. Zvinhu zvinokanganisa chiyero chekugara nekukurumidza kuomesa

1. tembiricha yemhepo: kana ichiwedzera tembiricha, kupararira kweyero yedikita mvura evaporation rate inowedzerwa. 2. hunyoro hwemhepo: pakunyorova kwepasi, chiyero chekubuda kwemvura chinova chikuru.

2. Humidity yemhepo: pakunyorova kwepasi, mwero wekubuda kwemvura unowedzera. 3.

3. Velocity yekuyerera kwemhepo: iyo inokurumidza kukurumidza, zviri nani mugumisiro wehuwandu uye kupisa kupisa.

4. Shrinkage uye kuoma kwepamusoro: izvi zviviri zviitiko zvichakanganisa kuoma.

III. Kurongeka kwemidziyo yekuomesa

Zvishandiso zvinofanirwa kubviswa zvakanyanya sezvinobvira kubva pamvura yakawandisa zvisati zvapinda mumidziyo.
