Isithombe: I-Modern Brewery Fermentation Tank

Isithombe sibonisa ukubuka okumangalisayo ngaphakathi kwendawo yokuphisa utshwala yesimanje, egxile ethangini lokuvutshelwa lensimbi ecwebezelayo. Ubuciko bethangi bubonakala ngokushesha, nendawo yalo eyinsimbi ebhulashiwe ebonisa okuvelele okuthambile futhi ibamba ukuhlangana okucashile kokukhanya nesithunzi. Umzimba oyisilinda wethangi uzizwa umkhulu futhi unembile, ubufakazi bomklamo wezimboni olungiselelwe ubuciko nesayensi yokuphisa. Okubusa ngaphambili iwindi elikhulu lokuhlola eliyindilinga, unqenqema lwalo lwensimbi olusindayo lwenza umbono okhangayo wobhiya ngaphakathi.

Ngaphakathi kwethangi, i-lager esagolide inyakaza namabhamuza ngamandla amakhulu. Uketshezi lubonakala luphila, ubuso balo bunamagwebu njengoba kuphuma isikhutha ngesikhathi sokuvutshelwa. Uketshezi olunyakazayo luyabenyezela emithunzini esukela kunhlaka ejulile kuya kuju olukhazimulayo olusagolide, okudala umphumela okhazimulayo ngokumelene nendawo epholile yensimbi. Ukukhanya kuza ngokumangalisayo ukusuka ohlangothini olulodwa, kusakaza okuvelele okufudumele kulo lonke uketshezi futhi kugcizelele isiphithiphithi esinamagwebu, kuyilapho izithunzi ezijulile zengeza ukuthungwa kanye nobukhulu. Lokhu kuhlangana kokukhanya nokunyakaza kudala umuzwa wokuqina nenqubekela phambili - ukuboniswa okubonakalayo kweyesti emsebenzini, kuguqula ushukela uwenze utshwala kanye ne-carbonation ngokungakhathali.

Amapayipi amabili aqinile ensimbi engagqwali, elinye lingena lisuka phezulu elinye lehle liye phansi, azungeze iwindi lokubuka. Lezi zinhlelo zigqamisa ubunkimbinkimbi bokusebenza kwezinto zokusebenza, zikhumbuza isibukeli buthule ngamasistimu akhiwe asekela ukuphisa ngaleli sikali. Umsebenzi wensimbi unenjongo kodwa unhle, uhlanganisa amandla ezimboni nomklamo ohlanzekile. Amabhawodi aphucuziwe kanye nokufakwa okuzungeze iwindi lokuhlola kugcizelela futhi ukuqina nokunemba okungangenisi umoya okudingekayo ekuvuthweni kochwepheshe.

Ingaphambili elingaphambili libekwe phezu kweplatifomu eqinile yokhuni noma unqenqema lwetafula, okusanhlamvu kwayo okuthulisiwe kugxilisa indawo yesehlakalo ngokufudumala kwemvelo, okungafani nensimbi ebandayo, ethambile yethangi. Lokhu kuhlangana kwezakhi zemvelo nezezimboni kwengeza ukujula ekwakhiweni, okubonisa imvelo embaxambili yokuphisa: kokubili isiko elingapheli elisekelwe izithako zemvelo kanye nenqubo yobuchwepheshe obuphezulu encike kubunjiniyela besimanje.

Ingemuva lesithombe lifiphalisiwe ngamabomu, okugcina ukunaka kombukeli kugxilile ethangini nomsebenzi osagolide ngaphakathi kwalo. Kodwa-ke, ngisho naphezu kokufiphala okuthambile, amacebo emikhumbi eyengeziwe yokuphisela kanye namathange amade okuvutshelwa angabonakala. Uhlaka lwazo olufiphele luphakamisa ubukhulu bendawo yokuphisa utshwala, ngezigaba eziningi zokukhiqiza ezenzeka ngesikhathi esisodwa. Ukukhanya okufiphele kwangemuva kuthuthukisa ngokwengeziwe ukukhazimula okumangalisayo kobhiya obilayo, bugqame njengenhliziyo yangempela yenqubo yokuphisa.

Iphalethi yombala iyonke yesithombe iwucwaningo ngokuqhathanisa: okumpunga okupholile namasiliva ensimbi engagqwali ngokumelene nokufudumala okukhazimulayo kwelager esagolide. Lawa mathoni ahambisanayo ahlanganiswe ngokusetshenziswa ngokucophelela kokukhanya, okudala kokubili ukusondelana nobukhulu emfanekisweni. Indawo idlulisa umuzwa onamandla wokusebenza kahle nokulawula. Akukho okuzwakala kunesiphithiphithi noma kungafaneleki; zonke izingxenye, kusukela emapayipini kuya efasiteleni kuya kubhiya obabazayo, kunomthelela ekubonakaleni kokunemba nenqubekela phambili.

Ngokomfanekiso, isithombe sihlanganisa ingqikithi yokuphisa kwesimanje. Ithwebula inyunyana yesiko nokuqanjwa okusha: ukuvutshelwa okuqhutshwa imvubelo, inqubo yebhayoloji yakudala, eyenzeka phakathi kwemikhumbi yensimbi engenasici eklanyelwe ukufana nekhwalithi. Isiphithiphithi esilawulwayo se-lager ephuphumayo sihlanganisa umsebenzi ongabonakali we-yeast, iguqula izithako ezingavuthiwe zibe isiphuzo esicolisisiwe. Ngaleso sikhathi, ithange lensimbi elizungezile, elinobunjiniyela obuphelele, ligcizelela umfutho womuntu wokucwenga, ukukala, kanye nokuphelelisa inqubo.

Kafushane, isithombe singaphezu nje kwerekhodi elibonakalayo lethangi lokuvutshelwa; iwukuvezwa okucacile kokwenza utshwala buhamba. I-golden lager ebabayo phakathi nendawo icwebezela ubungqabavu noshintsho, kuyilapho ingemuva elicwebezelayo, elilufifi likhumbuza umbukeli ngobunkimbinkimbi bezimboni obusekelayo. Ndawonye, adlulisa umbono onamandla wokwenza utshwala njengokubili ubuciko obusekelwe ezintweni zemvelo kanye nesayensi ehlanganiswe ngobuchwepheshe - umdanso olawulwayo kodwa onempilo weyeast, insimbi, nokukhanya.
