Isithombe: Ukuvutshelwa kwe-Lager Yeast ku-Lab Vessel

Lesi sithombe sithwebula umzuzwana wenguquko eguquguqukayo ngaphakathi kwendawo eyingxube ehlanganisa umhlaba wesayensi nokuphindwa kwemisebenzi yezandla. Okubusa ngaphambili umkhumbi omkhulu wengilazi obilayo, izindonga zawo ezibonisa ngale ziveza uketshezi lwenhlaka oluphilayo phakathi kokuvutshelwa okusebenzayo. Ingaphezulu loketshezi lithweswe umqhele wegwebu eliwugqinsi, elinamagwebu, kuyilapho imifudlana yamabhamuza amahle ikhuphuka ngokuqhubekayo ukusuka ekujuleni, okuwubufakazi obubonakalayo bokuqina komzimba wemvubelo yelager emsebenzini. Ukucaca komkhumbi kuvumela umbono oseduze wenqubo yokuvutshelwa, okubonisa ukunyakaza kwamangqamuzana emvubelo amisiwe kanye namaprotheni njengoba esebenzisana ne-wort, ekhulula i-carbon dioxide futhi alolonge iphrofayili ye-flavour kabhiya.

Ukukhanyisa kufudumele kodwa kuphansi, kuveza ukukhanya kwegolide kuwo wonke umkhumbi futhi kugqamisa i-effervescence ngaphakathi. Lokhu kukhanya akugcini nje ngokuthuthukisa ukukhanga okubonakalayo koketshezi olubilayo kodwa futhi kuvusa umuzwa wokufudumala nokunakekela, okuphakamisa ukuthi lesi indawo lapho isiko nokunemba kuhlangana khona. Umkhumbi ngokwawo uhlanzekile futhi unakekelwa kahle, izinsimbi zawo kanye nezimpawu zawo ziyabenyezela ngaphansi kokukhanya okuzungezile, okuqinisa ukubaluleka kokukhucululwa kwendle nokulawula enqubweni yokuphisa.

Phakathi nendawo, indawo yesehlakalo iyakhula ukuze ifake izinsimbi ezihlukahlukene zesayensi namathuluzi okuphisa. Ama-Hydrometer aphumula kumasilinda aneziqu, alungele ukukala amandla adonsela phansi athile futhi alandelele ukuncishiswa kukashukela. Ama-thermometer anqunywa eceleni komkhumbi, aqaphe izinga lokushisa ngokunemba okukhulu—okubalulekile imvubelo ye-lager, echuma ngaphansi kwezimo ezipholile futhi ekhiqiza ukunambitheka okuhlanzekile, okucwebezelayo lapho ilawulwa kahle. Amashubhu amasampula namapayipi alele eduze, okuphakamisa ukuthi ukuhlola okuvamile kuyingxenye yokuhamba komsebenzi, kungakhathaliseki ukuthi ngokwamazinga e-pH, ukusebenza kwamaseli, noma ukuthuthukiswa kokunambitheka. Lawa mathuluzi ahlelwa ngenjongo, abonisa indlela yokwenza uphuzo oludakayo eyazisa idatha nokungaguquguquki njengokusungula.

Ingemuva liyanyamalala libe endaweni ekhanyiswe kalufifi, ye-atmospheric brewery. Imiphongolo yokhuni ikleliswe ezindongeni, amafomu ayo agobile abonisa izinqubo zokuguga noma ezinye izindlela zokuvutshelwa. Izinyoka zamapayipi ensimbi kusilingi nasezindongeni, zakha inethiwekhi esekela ukudluliswa koketshezi, ukulawulwa kwezinga lokushisa, nokulawula ingcindezi. Ukukhanyisa lapha kuyamangalisa kakhulu—kuphansi futhi kuyaqondisa, izithunzi eziphonsayo ezengeza ukujula nokuthungwa kwesigcawu. Le ndawo yezimboni iphambene nengaphambili ehlanzekile, yomtholampilo, idala ukwakheka okunezingqimba okukhuluma nobunkimbinkimbi bokwenza utshwala besimanje.

Sekukonke, isithombe sidlulisa isimo sokubuza okugxilile kanye nekhono lobuciko. Ibungaza ibhalansi ethambile edingekayo ukuze kubiliswe i-lager yesitayela saseJalimane, lapho konke okuguquguqukayo—uhlobo lwemvubelo, izinga lokushisa, okuqukethwe ushukela, nesikhathi—kumele kulinganiswe ngokucophelela ukuze kuzuzwe umphumela oyifunayo. Ngokwakheka kwaso, ukukhanya, kanye nemininingwane, isithombe sixoxa indaba yokwenziwa kotshwala njengesayensi nobuciko, lapho umsebenzi ongabonakali wemvubelo uqondiswa izandla nezingqondo zomuntu ubheke emkhiqizweni wokugcina onoguquguqukayo, omnandi, nowanelisa ngokujulile. Imema umbukeli ukuthi athokozele ubuhle bokuvutshelwa hhayi nje njengenqubo, kodwa njengendlela yokuphila, ukubambisana okuthuthukayo phakathi kwesayensi yezinto eziphilayo kanye nenhloso.
