Kuo skiriasi naminis ir baro ledas<\/h2>\n

Namuose \u0161aldiklyje su\u0161aldyti ledo kubeliai da\u017enai b\u016bna balk\u0161vu, drumstu viduriu, o g\u0117rime i\u0161tirpsta grei\u010diau nei bar\u0173 kokteiliuose naudojamas skaidrus ledas. Tai n\u0117ra vien estetikos klausimas: drumstumas rodo, kad ledo strukt\u016bra susiformavo netolygiai.<\/p>\n

Skirtum\u0105 labiausiai lemia tai, kaip vanduo u\u017e\u0161\u0105la formel\u0117je. Namuose vanduo paprastai \u0161\u0105la nuo kra\u0161t\u0173 \u012f centr\u0105, tod\u0117l viskas, kas vandenyje i\u0161tirp\u0119, stumiama \u012f vid\u0173.<\/p>\n

Kas \u201eslepiasi\u201c drumstame centre<\/h2>\n

Pirmiausia prie formel\u0117s sieneli\u0173 u\u017e\u0161\u0105la palyginti \u0161varesnis vanduo, o i\u0161tirpusios dujos, mineralai ir kitos priemai\u0161os susitelkia kubelio centre. Ten jos \u012fstringa kaip daugyb\u0117 mikroskopini\u0173 oro burbuliuk\u0173, tod\u0117l vidurys ir atrodo baltas.<\/p>\n

Tokie burbuliukai veikia kaip ma\u017eyt\u0117s tu\u0161tumos, kurios ma\u017eina ledo tank\u012f ir silpnina jo vientisum\u0105. Kadangi strukt\u016bra por\u0117tesn\u0117, jai suirti ir pereiti \u012f vanden\u012f reikia ma\u017eiau \u0161ilumos energijos, tod\u0117l naminis ledas tirpsta grei\u010diau.<\/p>\n

\u201eDrumstas ledo kubelio centras rei\u0161kia, kad jame \u012fkalinta daugiau oro ir priemai\u0161\u0173, o tai spartina tirpim\u0105\u201c, \u2013 ai\u0161kina ledo gamybos technologij\u0173 ap\u017evalgose cituojami maisto mokslo specialistai.<\/p>\n

Kod\u0117l baruose ledas ilgiau laikosi<\/h2>\n

Profesionaliose ledo gaminimo sistemose da\u017enai taikomas kryptinis \u0161aldymas ir vandens judinimas. Vietoje to, kad vanduo ramiai sustingt\u0173 formel\u0117je, jis nuolat cirkuliuoja prie \u0161aldymo pavir\u0161iaus, tod\u0117l i\u0161tirpusios dujos ir priemai\u0161os ma\u017eiau \u201e\u012f\u0161aldomos\u201c \u012f kubel\u012f.<\/p>\n

Rezultatas yra tankesnis, skaidresnis ledas be oro ki\u0161eni\u0173, kuris tirpsta l\u0117\u010diau ir ma\u017eiau praskied\u017eia g\u0117rim\u0105. B\u016btent tod\u0117l kokteili\u0173 baruose ledas da\u017enai atrodo tarsi stiklas ir i\u0161laiko form\u0105 ilgiau.<\/p>\n

Forma ir dydis: paprasta fizika<\/h2>\n

Tirpimo greit\u012f stipriai veikia ir ledo gabalo dydis bei pavir\u0161iaus plotas. Didesni kubai ar ledo rutuliai turi ma\u017eesn\u012f pavir\u0161iaus ploto ir t\u016brio santyk\u012f, tod\u0117l \u0161iluma i\u0161 g\u0117rimo \u012f led\u0105 perduodama l\u0117\u010diau.<\/p>\n

Ma\u017ei, ploni ar netaisyklingi gabaliukai, kuriuos da\u017enai pagamina buitiniai ledo dozatoriai, turi daugiau pavir\u0161iaus, tod\u0117l \u0161yla grei\u010diau. D\u0117l to didelis kubas ar rutulys g\u0117rim\u0105 at\u0161aldo efektyviau, pats i\u0161tirpdamas l\u0117\u010diau.<\/p>\n","protected":false},"excerpt":{"rendered":"
