Imvamisa, kunezinhlobo ezimbili zokushintshanisa ukushisa endaweni yokuphisa utshwala, enye i-tubular heat exchanger, enye i-plate heatin exchanger.
Okokuqala, I-exchanger ye-tubular iwuhlobo lwesishintshi sokushisa esinamashubhu ahlanganiswe egobolondweni.Kuyidivayisi evame kakhulu ezimbonini lapho okugxilwe khona kuwukuthola ukushisa okuvela kugesi noma uketshezi.
Isimiso segobolondo nesishintshi sokushisa seshubhu sisekelwe kunqwaba yamashubhu ahlelwe ngokuqondile noma avundlile ngaphakathi kwegobolondo okuthiwa.
Isebenza ngokushintshanisa ukushisa phakathi koketshezi olubili.Enye "i-heater" kanti enye iwuketshezi "olushisayo".
Uketshezi lungaba ngokwezimo ezihlukahlukene futhi i-exchanger yamashubhu ingasetshenziswa ukushintshanisa igesi/igesi, uketshezi/uketshezi, uketshezi/igesi, njll.
Isishintshi sokushisisa amashubhu esisetshenziswa endaweni yokuphisa utshwala
-I-Tubular heat exchanger, Ukuvumela indawo yokuphisa utshwala ukuthi ipholise i-wort ngaphambi kokwengeza izengezo ze-whirlpool hop.Kukhona isishintshi sokushisa se-tubula sangaphandle sokupholisa i-wort ephumayo bese sibuyela emkhunjini.Ukupholisa i-wort ngokushesha futhi uthole izinga lokushisa elifanele lokwengeza ama-hops.
- Njengoba kwaziwa kahle, ukwehlisa izinga lokushisa lenhlabathi lifinyelele kuma-degree Celsius angama-80 futhi ukwengeza ama-hops kunenzuzo ekulondolozeni uwoyela we-hop.Kuleli zinga lokushisa, izinga le-isomerization ye-alpha valproic acid kuma-hops lizoba phansi kakhulu, ngakho-ke ngeke likhulise ukubaba kukabhiya.Kuleli zinga lokushisa, inani lezinto ezinephunga elimnandi elihwamukile ku-hops nalo lizoncishiswa kakhulu, futhi kulokhu kushisa, i-wort ingancibilikisa ngempumelelo ama-molecule anamakha angancibiliki kahle.Ngakho-ke leli zinga lokushisa yisigaba esifanele sokuzungeza ama-hops.
Kodwa-ke, lapho i-wort ebilisiwe idluliselwa ku-tank yokumiswa, izinga lokushisa layo lizoba ngu-98 ° C. Kuthatha isikhathi eside ukwehlisa izinga lokushisa lisuka ku-98 ° C liye ku-80 ° C. Ngakho-ke, ukuze kuthuthukiswe ukusebenza kahle nokulawula ukuphisa. izinga lokushisa le-wort kahle, sengeze isishintshi sokushisa lapha.
- Izosetshenziswa kabanzi endaweni yokuphisa utshwala ukuze kuthuthukiswe ukusebenza kahle kotshwala.
Okwesibili, i-plate heat exchanger
I-Heat Exchanger, ucezu lwesisetshenziswa sokuphisa utshwala esiklanyelwe ukukhuphula noma ukwehlisa ngokushesha izinga lokushisa le-wort noma likabhiya.Ukushintshanisa ukushisa ezindaweni zokuphuza utshwala kuvame ukubizwa ngokuthi “amapuleti okushisa amapuleti” ngoba akhiwe njengochungechunge lwamapuleti;uketshezi olushisayo lugeleza ohlangothini olulodwa lwepuleti bese uketshezi olubandayo lugeleza ngakolunye uhlangothi.Ukushintshana kokushisa kwenzeka kuwo wonke amapuleti.
Isishintshi sokushisa esivame kakhulu sitholakala ku-brewhouse.I-hot wort ecishe ibe ngu-95°C isetshenziswa endaweni yokushintshisana ukushisa, lapho ipholiswa khona ngamanzi abandayo kanye/noma isiqandisi esiza ngokuhlehla kwepuleti ngakolunye uhlangothi.I-wort iphola (isb., iye ku-12°C) futhi ilungele ukuvutshelwa, futhi amanzi abandayo afudunyezwe mhlawumbe afike ku-80°C futhi abuyiselwe ethangini lamanzi ashisayo, alungele ukusetshenziswa lapho kuphuzwa utshwala noma kwenye indawo endaweni yokuphisa utshwala. .Ngokwesilinganiso, izishintshisi zokushisa zizolinganiswa ukuze konke okuqukethwe kweketela kupholiswe kumazinga okushisa okuvutshelwa emizuzwini engama-45 noma ngaphansi.
Isishintshi sokushisa siwonga kakhulu amandla ngoba ukushisa okwase kusetshenziswe ekuqaleni ukubilisa kuphinda kusetshenziswe ingxenye ukushisisa amanzi abandayo angena endaweni yokuphisa utshwala.Ngokusebenzisa iziqandisi ezifana ne-glycol, izinto zokushisa amapuleti zingasetshenziswa futhi ukupholisa ubhiya emazingeni okushisa aphansi ngemva kokuvutshelwa, ukusho kusuka ku-12°C kuya ku-1°C, ukuze kukhule amakhaza.
Izinto ezishintsha ukushisa zingasetshenziswa ezicini eziningi zenqubo yokuphisa ukushisa nokupholisa ubhiya kanye nokushisa noma ukupholisa uketshezi olunjengamanzi.Nakuba izishintshi zokushisa zamapuleti zivame kakhulu, ezinye imiklamo yesishintshi sokushisa zingasetshenziswa, “njengegobolondo nesishintshi sokushisa seshubhu.”
Izishintshisi zokushisa nazo zisetshenziswa njengengxenye yokwakheka kwamayunithi e-flash pasteurization, ashisisa ubhiya ngokushesha ukuze uwuphuze, uwubambe isikhathi esifushane njengoba ugeleza ngamapayipi, bese wehlisa ngokushesha izinga lokushisa futhi.
