Ingabe ubhontshisi wekhofi othosiwe ungaphekwa ngokushesha? Yebo, kodwa hhayi ngempela ukuthi umnandi. Ubhontshisi wekhofi othosiwe osanda kuphekwa uzoba nesikhathi sokukhulisa ubhontshisi, okuwukukhipha i-carbon dioxide nokufeza isikhathi sokunambitheka okuhle kakhulu kwekhofi. Ngakho-ke sigcina kanjani ikhofi? Ukuze sigcine ubhontshisi wekhofi, sicabanga ukusebenzisa izikhwama zekhofi okokuqala, kodwa ingabe uke waqaphela ngokucophelela izikhwama zokupakisha ubhontshisi wekhofi? Wake waphawula ivalvu emhlophe noma ecacile ngemuva noma ngaphakathi kwesikhwama sekhofi? Noma ingabe ukubonile kodwa awuzange ukukhathalele? Ungacabangi ukuthi leli valve lingasuswa uma ubona ukuthi ivalvu incane. Eqinisweni, ivalvu encane iyimfihlo "yokuphila noma ukufa" kobhontshisi wekhofi.
Le valve yilokho esikubiza ngokuthi "i-coffee exhaust valve", futhi ibizwa ngokuthi i-one-way exhaust valve. I-one-way vent valve idlala indima ebalulekile ekusizeni ikhofi lakho elisha ukuthi lihlale lisha isikhathi eside. I-one-way vent valve ngaphakathi kwesikhwama sekhofi iyisengezo sesikhwama esivimbela ukugeleza komoya emuva. Ukubuka okufushane kwe-one-way exhaust valve kunemisebenzi emibili, omunye ukukhipha igesi esikhwameni, kanti omunye ukuhlukanisa umoya ongaphandle kwesikhwama sokupakisha ukuthi ungangeni. Okulandelayo, i-Wo intake valve izokwethula le misebenzi emibili nokuthi isebenza kanjani.
1. Ukukhipha ugesi,
Ubhontshisi wekhofi oluhlaza uqukethe ama-asidi, amaprotheni, ama-ester, ama-carbohydrate, amanzi kanye ne-caffeine. Ngemva kokuba ubhontshisi wekhofi oluhlaza ubhakiwe ekushiseni okuphezulu, i-carbon dioxide ikhiqizwa ngochungechunge lwezimo zamakhemikhali ezifana nokusabela kwe-Maillard. Ngokuvamile, i-carbon dioxide kanye namanye amagesi aguquguqukayo akhishwa ubhontshisi wekhofi obhakiwe abiza u-2% wesisindo sawo wonke ubhontshisi wekhofi. Futhi u-2% wegesi ukhishwa kancane kancane esakhiweni sefayibha yobhontshisi, futhi isikhathi sokukhishwa sizoncika endleleni yokosa. Ngenxa yokuthi ubhontshisi wekhofi ukhipha i-carbon dioxide ngokwawo, sizobona ubhontshisi wekhofi obhakiwe esikhwameni esivaliwe esizoqhuma ngokuhamba kwesikhathi. Lokhu kubizwa ngokuthi "isikhwama esifuthwe". Nge-valve yokukhipha umoya enendlela eyodwa, kuzosiza ukususa la magesi angangeni esikhwameni ngesikhathi, ukuze la magesi angangenisi ubhontshisi wekhofi futhi agcine isimo esihle sokusha kobhontshisi wekhofi.
2.hlukanisa umoya,
Ungawuhlukanisa kanjani umoya ngenkathi uwukhipha? I-valve yendlela eyodwa ihlukile kune-valve yomoya evamile. Uma kusetshenziswa i-valve yomoya evamile, ngenkathi igesi esesikhwameni sokupakisha ikhishwa, izovumela nomoya ongaphandle kwebhande lokupakisha ukuthi ungene esikhwameni, okuzolimaza ukusebenza kokuvala kwesikhwama sokupakisha futhi kubangele ukuthi ikhofi iqhubeke nokugcwala. Ukugcwala kwe-oxidation kwamabhontshisi ekhofi kuzobangela ukuguquguquka kwephunga kanye nokuwohloka kokwakheka. I-valve yokukhipha umoya yendlela eyodwa ayikwenzi lokho, ikhipha i-carbon dioxide esesikhwameni ngesikhathi, futhi ayivumeli umoya wangaphandle ukuthi ungene esikhwameni. Ngakho-ke, ikwazi kanjani ukungavumeli umoya wangaphandle ukuthi ungene ebhandeni? I-valve yokungenisa i-Wo ikutshela isimiso sayo sokusebenza: lapho umfutho womoya esikhwameni ufinyelela umkhawulo othile, i-valve ye-valve yokukhipha umoya yendlela eyodwa iyavuleka ukuze ikhulule igesi esikhwameni; kuze kube yilapho umfutho womoya wehla ngaphansi komkhawulo we-valve yendlela eyodwa. I-valve ye-valve yendlela eyodwa ivaliwe, futhi isikhwama sokupakisha sibuyela esimweni esivaliwe.
Ngakho-ke, siphethe ngokuthi ukuhambisana kwevalvu yokukhipha ikhofi kuyindlela eyisisekelo kakhulu, futhi futhi iyimfuneko ethuthukisiwe kakhulu. Uma ubhontshisi wekhofi ubhakwa kakhulu, umphumela wokukhipha uzoba namandla, futhi i-carbon dioxide izokhishwa ngokushesha.
