Isithombe: I-Fermentation Tank ene-Temperature Control

Lesi sithombe sithwebula ukushuba okuthulile kwendawo yokuphisa utshwala, lapho idizayini yezimboni ihlangabezana nokunemba kwebhayoloji emzamweni wokwenza ubhiya okhethekile. Enkabeni yokwakheka kukhona ithangi lokubilisa lensimbi engenasici, indawo yalo epholishiwe ibenyezela ngokucashile ngaphansi kokukhanya okuthambile, okuzungezile okungena endaweni ekhanyiswe kalufifi. Ifomu le-cylindrical yethangi liyasebenza futhi lihle, libonisa ubuhle obusetshenziswayo bemishini yokuphisa yesimanje. Okuboniswa kahle ngaphambili kwayo izinga lokushisa ledijithali elifundwayo, elikhazimulayo ngokucaca okucacile okudonsa iso lesibukeli. Ukufundwa—20.7°C—kubonisa indawo yangaphakathi enakekelwa ngokucophelela, eklanyelwe izidingo ezithile zohlobo lwemvubelo ebilayo ngaphakathi.

Ukubonisa izinga lokushisa kungaphezu kwemininingwane yobuchwepheshe; kuwuphawu lokulawula nokunaka. Ekuvubeleni, izinga lokushisa liyinguquko ebalulekile—ifudumele kakhulu, futhi imvubelo ingase ikhiqize ama-ester angafuneki noma ama-alcohol e-fusel; kubanda kakhulu, futhi inqubo ihamba kancane, ibeka engcupheni yokuncipha okungaphelele. Ukunemba kwalesi siqapha sedijithali kuphakamisa umenzi wotshwala oqonda ibhalansi ethambile edingekayo ukuze axube ukunambitheka okungcono kakhulu kweyeast, aqinisekise ukuthi ubhiya uthuthukisa uhlamvu oluhlosiwe ngalo ngokuvumelana nangokucophelela. Insimbi ezungezile ibushelelezi futhi ayinamathekisthi, ikhombisa izimiso eziqinile zokukhucululwa kwendle kanye nokuzibophezela kwikhwalithi.

Ngaphezulu kwesibonisi sezinga lokushisa, i-valve ne-pressure fitting iphuma endaweni yethangi, okungenzeka isetshenziselwa ukudlulisa uketshezi, ukusampula, noma ukulawula ukucindezela. Lezi zingxenye zibalulekile ekulawuleni ukuguquguquka kwangaphakathi kokuvutshelwa, okuvumela ukukhululwa okuphephile kwe-carbon dioxide noma ukwethulwa kwezithasiselo ngaphandle kokufaka engozini indawo eyinyumba. I-hatch yokufinyelela eyindilinga, evikelwe ngomshini wokukhiya, yengeza olunye ungqimba lokusebenza, okuvumela ukuhlanzwa noma ukuhlola kuyilapho kugcinwa ubuqotho bomkhumbi ngesikhathi sokuvutshelwa okusebenzayo.

Ingemuva lesithombe lifiphaliswe kancane, liveza izinkulumo zamathangi engeziwe namapayipi akha ingqalasizinda yendawo yokuphisa utshwala. Lokhu kujula okucashile kuphakamisa isistimu enkulu emsebenzini, lapho amaqoqwana amaningi angase abilayo ngesikhathi esisodwa, ngalinye liqashwe ngokunakekelwa okulinganayo. Ukukhanyisa kuyo yonke indawo kuyafudumala futhi kuyaqondisa, kuveza izithunzi ezithambile ezithuthukisa amakhonto ethangi futhi zidale umuzwa wokusondelana. Ivusa umuzwa wokungena ebusuku kakhulu, lapho umenzi wotshwala ehamba khona phansi, elalela umsindo othulile wemishini futhi ebuka izinombolo zicwayiza ezibukweni.

Sekukonke, isithombe sidlulisa umoya wokunemba ozolile nokuzinikela okuthule. Ibungaza ukuphambana kwesayensi nemisebenzi yezandla, lapho ubuchwepheshe busekela khona isiko nalapho yonke imininingwane—kusukela ekugobeni kwethangi kuya ekukhanyeni kwesibonisi sezinga lokushisa—idlala indima ekulondolozweni komkhiqizo wokugcina. Ngokubunjwa kwaso, ukukhanya, nokugxila, isithombe sixoxa indaba yokuvutshelwa hhayi njengenqubo yesiphithiphithi, kodwa njengenguquko elawulwayo eqondiswa ubungcweti nokunakekelwa. Imema umbukeli ukuthi ajabulele umsebenzi ongabonakali ngemuva kwephayinti ngalinye likabhiya, futhi abone ithangi hhayi nje njengomkhumbi, kodwa njengesitsha sokunambitha, isiyalo, kanye nenhloso.
