Nthawi zambiri, pamakhala mitundu iwiri yowotchera moŵa, imodzi ndi yowotchera ma tubular, ina ndi mbale heatin exchanger.
Choyamba, Tubular exchanger ndi mtundu wa chosinthira kutentha chokhala ndi machubu ozunguliridwa ndi chipolopolo.Ndi chipangizo chofala kwambiri m'mafakitale omwe cholinga chake ndikubwezeretsa kutentha kwa gasi kapena zakumwa.
Mfundo ya chipolopolo ndi chubu kutentha exchanger zachokera mtolo wa machubu kuti anakonza vertically kapena horizontally mkati mwa otchedwa chipolopolo.
Zimagwira ntchito posinthanitsa kutentha pakati pa madzi awiri.Chimodzi ndi "kutentha" ndipo china ndi "kutentha" madzimadzi.
Madziwo amatha kukhala amitundu yosiyanasiyana ndipo chosinthira ma tubular chingagwiritsidwe ntchito posinthanitsa gasi / gasi, madzi / madzi, madzi / gasi, ndi zina.
Chowotcha chotenthetsera cha tubular chomwe chimagwiritsidwa ntchito popangira moŵa
-Tubular heat exchanger, Kulola kuti moŵa aziziziritsa wort asanawonjezere zowonjezera za whirlpool hop.Pali kunja kwa tubular kutentha exchanger kuziziritsa liziwawa kutuluka ndi kubwerera mu chombo.Kuziziritsa liziwawa posachedwa ndikupeza kutentha koyenera kuwonjezera hops.
- Monga momwe zimadziwikiratu, kutsitsa kutentha kwa sedimentation kufika pafupifupi madigiri 80 Celsius ndipo kuwonjezera ma hop ndikopindulitsa kusungitsa mafuta a hop.Pa kutentha uku, mlingo wa isomerization wa alpha valproic acid mu hops udzakhala wotsika kwambiri, choncho sichidzawonjezera kuwawa kwa mowa.Pakutentha uku, kuchuluka kwa zinthu zonunkhiritsa kuchokera ku ma hop kudzachepetsedwa kwambiri, ndipo pakutentha uku, wort amatha kusungunula mamolekyu onunkhira osasungunuka bwino.Chifukwa chake kutenthaku ndi gawo loyenera kwambiri pozungulira ma hop.
Komabe, wort yophika ikasamutsidwa ku thanki yoyimitsidwa, kutentha kwake kumakhala pafupifupi 98 ° C. Zimatenga nthawi yayitali kuti muchepetse kutentha kuchokera ku 98 ° C mpaka 80 ° C. kutentha kwa wort bwino, tawonjezera kutentha kuno.
- Idzagwiritsidwa ntchito kwambiri popanga moŵa waung'ono, popanga moŵa wamalonda kuti apange moŵa bwino.
Kachiwiri, mbale Kutentha exchanger
Heat Exchanger, chida chopangira moŵa chomwe chimapangidwira kukweza kapena kutsitsa kutentha kwa wort kapena moŵa.Zotenthetsera kutentha m'mafakitale nthawi zambiri zimatchedwa "zotentha za mbale" chifukwa zimamangidwa ngati mbale zotsatizana;madzi otentha amayenda mbali imodzi ya mbale ndipo madzi ozizira amayenda mbali inayo.Kusinthana kwa kutentha kumachitika pa mbale.
Chotenthetsera chofala kwambiri chimapezeka m'malo opangira mowa.Wort wotentha pafupifupi 95 ° C amayendetsedwa ndi chotenthetsera kutentha, komwe amaziziritsidwa ndi madzi ozizira ndi / kapena firiji yomwe imabwera kumbali yakumbuyo kwa mbaleyo kwina.Wort amakhala ozizira (mwachitsanzo, mpaka 12 ° C) ndikukonzekera kuwira, ndipo madzi ozizira amatenthedwa mpaka 80 ° C ndipo amabwezeretsedwa ku thanki lamadzi otentha, okonzeka kugwiritsidwa ntchito pophika motsatira kapena kwina kulikonse. .Pa avareji, zotenthetsera zidzakulitsidwa kotero kuti zonse zomwe zili mu ketulo zitha kukhazikika mpaka kutentha kwa 45 min kapena kuchepera.
Chotenthetsera kutentha chimakhala ndi mphamvu zambiri chifukwa kutentha komwe kunkagwiritsidwa ntchito kubweretsa wort kuwira kumagwiritsidwanso ntchito pang'ono kutenthetsa madzi ozizira omwe amalowa m'mowa.Pogwiritsa ntchito mafiriji monga glycol, zotenthetsera mbale zingagwiritsidwenso ntchito kuziziritsa mowa mpaka kutentha kochepa pambuyo powira, kunena kuti kuchokera pa 12 ° C mpaka -1 ° C, kuti akhwime.
Zotenthetsera zitha kugwiritsidwa ntchito m'njira zambiri zofukira kuti zitenthetse ndi kuziziziritsa moŵa komanso kutenthetsa kapena kuziziritsa zamadzimadzi monga madzi.Ngakhale zosinthira kutentha kwa mbale ndizofala kwambiri, njira zina zosinthira kutentha zitha kugwiritsidwa ntchito, monga “chigoba ndi chosinthira kutentha kwa chubu.”
Zotenthetsera kutentha zimagwiritsidwanso ntchito ngati gawo la mapangidwe a mayunitsi a pasteurization, omwe amatenthetsa mowa mwachangu kuti asawuke, kuugwira kwakanthawi kochepa pamene ukuyenda m'mipope, kenako ndikuchepetsanso kutentha mwachangu.
