Isithombe: Commercial Brewery Ukuvutshelwa

Enhliziyweni yelabhorethri yesimanje yotshwala, ingilazi enkulu ye-carboy iyala ukunakwa njengendawo okugxilwe kuyo yenqubo esebenzayo yokuvutshelwa. Iphumula ngokuvikelekile phezu kweplatifomu yensimbi engagqwali—okungenzeka isikali esinembayo noma isisekelo esizungezayo—i-carboy igcwele uketshezi olunenhlaka olucebile, ubuso bayo buthweswe umqhele wekrausen owugqinsi, onamagwebu okubonisa umsebenzi wemvubelo onamandla. Igwebu, elifakwe umbala o-tan ophaphathekile nama-cream okhilimu, linamathela ezindongeni zangaphakathi zomkhumbi, lenze indandatho eqoshiwe ephawula igagasi eliphezulu lokuvutshelwa. Ngaphakathi oketshezini, amabhamuza amahle akhuphuka esuka phansi, alandele izindlela ezithambile eziya phezulu njengoba isikhutha siphuma emsebenzini wokugaya imvubelo oguqula ushukela ube utshwala negesi. Umkhumbi uvalwe ngesivalo senjoloba esibomvu esiqinile, esifakwe isivalo se-airlock esisobala esimise okuka-S esiqhumisa ngobumnene igesi eningi kuyilapho siqapha ukungcola okuphuma emoyeni—indlela elula kodwa enhle egcizelela ibhalansi phakathi kokulawula nemvelo kwisayensi yokuphisa utshwala.

Ezizungeze i-carboy ebhentshini lokusebenza kukhona amathuluzi amaningana abalulekile wobuciko bomshini wokuphisa utshwala. Kwesokunxele, isilinda esincane esithweswe iziqu siphethe isampula yoketshezi lwenhlaka olufanayo, okungenzeka ukuthi ludwetshelwe ukufundwa kwamandla adonsela phansi noma ukuhlaziya izinzwa. Ukucaca nombala wayo kuphakamisa i-wort ekhule kahle, enothile ngezinhlamvu ze-malt futhi elungele ukuguqulwa. Eceleni kwayo, iflaski le-Erlenmeyer eliyindilinga liqukethe umthamo ofanayo woketshezi, okungenzeka ukuthi isiqalo semvubelo noma isixazululo sezakhi, esilungiselelwe ukuthuthukisa izimo zokuvutshelwa. Kwesokudla se-carboy, isitsha sengilazi esingashoni siphethe into eyimbudumbudu—yeast yotshwala eyomile, izinhlamvu zayo ezi-tan kanye ne-beige ezilindele ukuvuselelwa futhi zifakwe emanzini. Ukuhlelwa kwalezi zinto kokubili kuyasebenza futhi kungokomfanekiso, okumelela ukuhlangana kwebhayoloji, ikhemistri, nobuciko obuchaza inqubo yokuphisa.

Ingemuva elilufifi kancane, ama-fermenters ensimbi engagqwali amade aphakama njengabalindi, izindawo zawo ezipholishiwe zibenyezela ngaphansi kokukhanya, ngisho nokukhanya. Le mikhumbi yezimboni, exhunywe uxhaxha lwamapayipi namavalvu, ikhombisa izinga kanye nokuba yinkimbinkimbi komsebenzi. Zihluke kakhulu ekumisweni kwelabhorethri okusondele kakhulu ngaphambili, okuphakamisa ukuthi lesi sigcawu sithwebula umzuzu wokuhlolwa kwenqwaba encane noma ukulawulwa kwekhwalithi ngaphakathi komongo omkhulu wezohwebo. Ukukhanyisa kungokomtholampilo kodwa kufudumele, kukhanyisa yonke imininingwane ngaphandle kokukhipha izithunzi ezinokhahlo, futhi kunomthelela emuzweni wokuhlanzeka nokunemba okungena endaweni.

Lesi sithombe sihlanganisa amandla athule okuvutshelwa—inqubo eyakudala futhi ecwengisiswe ngokungapheli. Ikhuluma ngendima yomenzi wotshwala hhayi nje uchwepheshe, kodwa njengomphathi wezinguquko, eqondisa izithako ezingavuthiwe ohambweni oluyinkimbinkimbi lwe-biochemical oluya ekunambithekeni, iphunga, kanye nomlingiswa. Amathuluzi nezitsha, nakuba ziwusizo, zinomqondo wesiko nenjongo. Ibhamuza ngalinye, indandatho ngayinye eyigwebu, isampula ngayinye elinganiswe ngokucophelela iyiphoyinti ledatha ekuhlolweni okuphilayo, okwembuleka ngesikhathi sangempela. Kulo mzuzu, indawo yokuphisa utshwala iba yindawo yokucwaninga yokuphila, lapho isayensi nobuciko buhlangana khona siphishekela ipinti ephelele.
