Okokuqala, kufuneka siqonde inkqubo eyisiseko ye-coffee latte art. Ukuzoba ikomityi egqibeleleyo yobugcisa bekofu yekofu, kufuneka ubambe izinto ezimbini eziphambili: ubuhle be-emulsion kunye nokwahlula.
Ubuhle be-emulsion bubhekisela kwi-foam egudileyo, ecebileyo yobisi, ngelixa ukwahlukana kubhekisela kwimeko yobisi kunye nekhofi. Ukudityaniswa kwezi zinto zimbini kunokudala i-coffee latte art emangalisayo. Ngoko, kutheni ubisi lwenze igwebu? Oku kubandakanya imigaqo yokuxinana komphezulu kunye nokwakheka kweqamza kwifiziksi
Amafutha kunye neprotheyini ebisi zizithako eziphambili ekwenzeni ugwebu. Xa ubisi lufudunyezwa, amanqatha ayanyibilika kwaye iiproteni ziyaguquka. Ngaloo ndlela, abantu abaqhelana nemigaqo ye-foam baya kukwazi ukuba ukubunjwa kwe-foam akunakuhlukaniswa noxinzelelo oluphezulu. Ukuxinana komphezulu sisiphumo sokudibana phakathi kweemolekyuli zolwelo kwaye yipropathi ebangela umphezulu wolwelo ukuba uthande ukunciphisa amandla. Amanqatha kunye neeprotheyini zeprotheyini ebisi ziqokelela phezu kolwelo, zenza ifilimu encinci njengesakhiwo. Kule inwebu ibhityileyo, umoya uvaleleke ngaphakathi, wenze amaqamza amancinane. Xa ubisi lufudunyezwa, la maqamza ayanda kwaye agcine imilo ethile kunye nokuzinza.
Okulandelayo, makhe sijonge ukwahlulwa kobisi. Xa ubisi luxutywe nekhofi, ubisi kunye nekhofi ziya kuhlukana ngenxa yokungafani kobuninzi kunye ne-viscosity. Ngethuba le nkqubo, iipateni ezininzi ezintle zinokuqulunqwa kwindebe ngokusebenzisa imisebenzi ehlakaniphile. Enyanisweni, kukho imigaqo yenyama emva kwale nto yokubeka. Ukwahlula phakathi kobisi kunye nekofu kubangelwa ukuhlukana kobuninzi. Ubisi luxinene kunekofu, ngoko luya kutshona ngelixa ikofu iya kudada ngaphezulu. Ukuze wenze iipatheni ezahlukeneyo, ubisi kufuneka lugalelwe kwindebe kwiindawo ezahlukeneyo ukuze kufezekiswe umphumo oyifunayo.
Ukongeza kubudlelwane phakathi kwegwebu kunye nokwahlula, kukho enye ingcamango yefiziksi ebalulekileyo ekufuneka ikhankanyiwe, kwaye leyo yinombolo yeReynolds. Inombolo yeReynolds linani elingenamlinganiselo elisetyenziselwa ukuchaza ukuhamba kolwelo ngezantya ezahlukeneyo kunye noxinzelelo. Kwi-coffee latte art, ngokutshintsha isantya kunye ne-angle yokuthulula ubisi, ukuhlukana kobisi kunye nekhofi kunokuchaphazeleka. Xa isantya sihamba ngokukhawuleza, i-fluid iyahlukana ngokupheleleyo, kwaye xa isantya sihamba kancinci, imigca emihle kunye nepateni ecacileyo yenziwa.
I-coffee latte art idibanisa ukubunjwa kwe-foam kunye nokuhlukana kobisi kunye nekhofi ngokusetyenziswa kwemigaqo yomzimba. Ngokusebenza kakuhle, iipateni ezahlukeneyo ezintle zinokuqulunqwa kumphezulu wekofu, ukubonelela abantu ngokuzonwabisa okubonakalayo. Ngokuqonda imigaqo, sinokuyixabisa ngakumbi kwaye siqonde ubugcisa be-coffee latte art, kwaye sizame ukudala imisebenzi emangalisayo ngakumbi xa sisebenza ngezandla zethu. Nangona eli nqaku lichaza ngokufutshane imigaqo ye-coffee latte art, siyathemba ukuba abafundi banokuqonda obu bugcisa ngokwembono yefiziksi. Ubugcisa beCoffee latte bubuchule obukhethekileyo obudibanisa imigaqo yenzululwazi kunye nobuchule bobugcisa, busizisela ulonwabo oluhle. Nokuba senza eyethu okanye incasa umsebenzi wabanye abantu, sinokuba namava anzulu omtsalane wekofu.
