Downflow type inoreva kuti mafambiro ekuyerera kwemhepo inopisa yakafanana neiyo yezvinhu, zvese zvichifamba kubva kumagumo ekudya kusvika kumagumo ekubuda. Kana izvo zvinyorwa zvinongopinda mudhiramu, iyo yekuomesa kutyaira ndiyo yakakura uye yemahara yemvura yemukati yakakwira. Iko kumhanya kwekuomesa kwechikamu chepamberi cherudzi rwekuyerera ndiyo inokurumidza, uyezve sezvo zvinhu zvinofamba kuenda kuchiteshi chekuburitsa, tembiricha yezvinhu inowedzera, simba rekuomesa rinoita diki, hunyoro hwemahara hunodzikira, uye kumhanya kwekuomesa. zvakare inononoka. Nokudaro, kuomeswa kwedhiramu rekudzikisa-kuyerera kunonyanya kusaenzana kupfuura rudzi rwe-counter-flow.

Iyo counter-yekuyerera mhando ndeyokuti kuyerera kwemhepo inopisa inoyerera yakatarisana nekufamba kwechinyorwa, uye tembiricha yedhiramu ndiyo yepamusoro-soro pamagumo ekubuda kwezvinhu, uye tembiricha yakadzikira panoperera zvinhu. . Tembiricha yemidziyo ndiyo yakadzikira painotanga kupinda mudhiramu, uye tembiricha ndiyo yakakwira pakupera kwekubuda, iyo iri munzira imwe chete neyepamusoro uye yakaderera tembiricha yedhiramu. Nekuti tembiricha yepamusoro yechigubhu iri padivi rakafanana netembiricha yepamusoro yechinhu, uye tembiricha yakaderera yedhiramu iri padivi rimwechete seyakadzika tembiricha yechinhu, saka simba rekutyaira rekuomesera kwakaringana rinowedzera kufanana. kupfuura iyo yekuomeswa kwemvura.

Kazhinji, kupisa kwedhiramu kunonyanya kuitwa nekupisa convection. Mhando yekudzika-kuyerera inoreva kuti kamuri yekupisa uye yekudyira inlet yakaiswa kune rimwe divi, uye mafambiro ekuyerera kwemhepo inopisa inoyerera yakafanana neyechinyorwa. Zvikasadaro, imhando yekupikisa-kuyerera.

Kana iyo counter-inoyerera dhiramu iri kuomesa uye kupisa, mukati meiyo dhiramu yekuomeswa inogona kukamurwa kuita nzvimbo nhatu zvichienderana nekushanduka kwekushisa kwezvinhu: dehumidification nzvimbo, nzvimbo yekuomesa uye yekudziya nzvimbo. Nekuti zvinhu zvacho zvine hunyoro pazvinotanga kupinda mudhiramu, hunyoro huri muzvinhu huchabviswa munzvimbo yekutanga, iyo yakaunganidzwa ichaomeswa munzvimbo yechipiri, uye dhiramu richange riri pakupisa kwepamusoro munzvimbo yechitatu Bata ne. iyo yakaomeswa zvinhu kusimudza tembiricha. Kazhinji, sezvo tembiricha yechinhu ichiwedzera mudhiramu re-counter-current, iyo yekuomesa yepakati inowedzerawo, saka simba rekuomesa rakafanana, avhareji yetembiricha musiyano pakati pekuyerera kwemhepo inopisa uye zvinhu zvakakura, uye kugona kwe iyo counter-current drying inenge yakatsetseka. kuyerera kumusoro.

Padrum-type asphalt mixing plant, ngoma ine mabasa maviri, kuomesa uye kusanganisa; apo pabatch asphalt kusanganisa chirimwauyeinoenderera mberi asphalt kusanganisa chirimwa, ngoma inongoridza basa rekudziya. Nokuti kusanganiswa mubatch uye kuenderera mberi kweasphalt kusanganiswa kwemiti kunoitwa kuburikidza nehari yekuvhenganisa, hapana chikonzero chekuwedzera asphalt kune dhiramu yekusanganiswa, saka iyo countercurrent drying drum ine high dryness effect inoshandiswa.
