Drying midziyo yekuomeswa mwero inopesvedzera zvinhu uye kuomesa midziyo yemhando

Drying midziyo yekuomeswa mwero inopesvedzera zvinhu uye kuomesa midziyo yemhando

I. Drying equipment drying rate 1. Drying equipment drying rate

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

2. kuomesa nzira

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

(2) Nguva inogara ichimhanya: iyi ndiyo mwero wekuoma ^ nguva yenguva, kubuda kwemvura pamusoro pemvura, mukati inongokwana kuzadza, saka pamusoro pemvura.

(3) Kuderera kweimwe nguva yenguva: panguva ino yekubuda kwemvura, mukati haigoni kuzadzikiswa zvachose, saka pamusoro pemvura firimu yakatanga kuputika, kuoma kwemvura kwakatanga kuderera, zvinhu zvinonzi chikumbaridzo panzvimbo iyi, mvura iri panguva ino, inozivikanwa semvura inokosha.

(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, firimu remvura riri pamusoro penguva yechipiri rakapera zvachose, saka mvura inopararira kumusoro nenzira yemhute yemvura.

II. Zvinhu zvinokanganisa chiyero chekugara nekukurumidza kuomesa

1. Kupisa kwemhepo: Kana kutonhora kuchiwedzerwa, chiyero chekupararira uye chiyero chekubuda kwemvura chinowedzerwa. 2.

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

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

4. Shrinkage uye kuoma kwepamusoro: zvose zviitiko zvinokanganisa kuoma.

III. Kurongeka kwemidziyo yekuomesa

Mvura yakawandisa inofanira kubviswa zvakanyanya sezvinobvira zvinhu zvisati zvapinda mumudziyo.
