I-coffee stick iyithuluzi elisebenziseka kalula lokwenza ikhofi, ngokuvamile elenziwa ngokucindezela ingxube yempushana yekhofi esheshayo, ushukela, ukhilimu, nesithwali esincibilikayo (njenge-maltodextrin noma inhlaka). Umgomo wayo oyinhloko ukukhulula ngokushesha ukunambitheka kwekhofi ngokuncibilika emanzini abandayo noma ashisayo, kunikeze ukuphuza okusheshayo. Okulandelayo kuchaza umgomo wayo wokusebenza ngokwemibono yesayensi yezinto ezibonakalayo, indlela yokuqedwa, nezimo zokusetshenziswa.
I. Ukubunjwa Kwempahla kanye Nezakhiwo Zomzimba
Izithako eziyinhloko zenduku yekhofi zihlanganisa:
1.Impushana yekhofi esheshayo: Ihlinzeka ngokunambitheka okuyisisekelo kanye nephunga elimnandi lekhofi futhi livamise ukuba yiqhwa-lomisiwe noma lifuthwe{2}}lomisiwe ukuze lincibilike kakhulu.
2.Ama-sweeteners nama-emulsifiers: Okufana noshukela, izinto ezishintsha ushukela, noma{1}}okungezona izikhilimu zobisi, lungisa ukunambitheka futhi uthuthukise ukushelela ngemva kokuncibilika.
3.Ama-Binders: Okufana ne-maltodextrin noma i-hydroxypropyl methylcellulose (HPMC), qinisekisa ukuthi induku yekhofi yakheka ngesikhathi sokucindezela futhi ihlakazeka ngokulinganayo lapho ivezwe emanzini.
Lezi zithako zicindezelwa ngaphansi kwengcindezi ephezulu ukuze zenze induku eqinile. Ukuminyana kwayo kanye ne-porosity kunomthelela ngokuqondile izinga lokuqedwa kwayo. Isibonelo, isakhiwo esinezimbotshana sisheshisa ukungena kwamanzi, kuyilapho inani le-binder elisetshenzisiwe kufanele lilinganise ubulukhuni nokuncibilika.
II. Izimiso Zokuqedwa kanye Nenqubo
Ukuhlakazwa kwezinti zekhofi kuncike ekusakazweni nasekuhlakazweni:
1.Ukungena kwamanzi: Uma amanzi ashisayo noma abandayo ethinta indawo engaphezulu yenduku yekhofi, amanzi angena ezimbotsheni zangaphakathi ngokusebenzisa isenzo se-capillary, encibilikisa impushana yekhofi esheshayo nezinye izithako ezincibilikayo.
2.Ukusabalalisa kwamangqamuzana: Ama-molecule ekhofi ancibilikisiwe asakazeka ngenxa yokuhluka kokugxilisa ingqondo, enza isisombululo esifanayo. Amazinga okushisa aphezulu akhuphula amandla e-molecular kinetic futhi asheshise izinga lokuqedwa (isibonelo, amanzi ashisayo ngokuvamile ancibilikisa induku yekhofi ngokuphelele phakathi kwamasekhondi angu-5-10).
3.Ukumiswa kanye ne-emulsification: Uma izithako ezikhilimu noma zikawoyela zikhona, ama-emulsifiers avimbela ukuhlaliswa kwezinhlayiyana futhi aqinisekise ukunambitheka okubushelelezi.
Kuyaphawuleka ukuthi ama-coffee sticks abandayo-amanzi{1}}ancibilikayo angase aqukathe amanye ama-surfactants (afana ne-carrageenan) ukuze anciphise ukushuba kwamanzi futhi akhuthaze ukuncibilika kahle emazingeni okushisa aphansi.
III. Izimo zohlelo lokusebenza kanye nezinzuzo
Izinti zekhofi ekuqaleni zaziklanyelwe ukubhekana nezinhlungu zekhofi lendabuko elisheshayo, elithembele ezinkeni noma emaphaketheni. Izinzuzo zabo zihlanganisa:
Ukuphatheka: Zipakishwe ngazinye, zilungele ukusetshenziswa ngaphandle, umsebenzi, noma uhambo.
Ulungele-ukusebenzisa-ukusetshenziswa: Azikho izinkomishi zokulinganisa noma amathuluzi okunyakazisa adingekayo; mane ungeze kuketshezi nesiphuzo.
Ukunambitheka Okujwayelekile: Ukukhiqizwa okuthuthukisiwe kulawula izilinganiso zesithako, kuqinisekisa ukunambitheka okungaguquki kwenduku ngayinye.
Ukwengeza, eminye imikhiqizo emisha (efana nezinti zekhofi ezinama-probiotics noma ubuchwepheshe be-nitrogen cold Brew) iqhubekisele phambili yandise ukusebenza kwayo, njengokwelula impilo yeshelufu noma ukulingisa ukunotha kwekhofi eligayiwe.
IV. Imikhawulo kanye namathrendi okuthuthuka
Nakuba izinti zekhofi zilula futhi zisebenza kahle, inkimbinkimbi yazo yokunambitheka ngokuvamile incane kunaleyo yekhofi elisanda kufakwa, futhi eminye imikhiqizo iqukethe amazinga aphezulu kashukela nezithasiselo. Izikhombisi-ndlela zentuthuko yesikhathi esizayo zingabandakanya:
Izithako{0}}zoshukela/akukho{1}}ezinezengezo eziphansi: ukunakekela impilo-abathengi abaqaphelayo;
Ubuchwepheshe obukhethekile bokwenza utshwala obubandayo: ukwenza ngcono iphrofayili yokunambitheka kokuncibilika kwamanzi abandayo;
Izinto ezibolayo eziphilayo: ukunciphisa umthelela wendawo.
Kafushane, i-coffee stick ifinyelela isipiliyoni sokuphuza ikhofi esincane ngokuhlanganisa isayensi yezinto ezibonakalayo kanye namandla okuchithwa. Izimiso zayo nezikhombisi-ndlela zokuthuthukisa ziyaqhubeka nokuqhuba ukuqanjwa kabusha kobuchwepheshe bokudla obulula.
