I-Tempering iyisinyathelo sokugcina ekukhiqizeni futhi inomthelela omkhulu ekuhlangenwe nakho kokugcina kukashokoledi kubathengi.Uke waba nebha kashokoledi eyayibhidlika futhi inefilimu emhlophe opaque ngaphandle?Kungenzeka ukuthi ukuthambisa akwenziwanga kahle noma kukhona okungalungile ngezithako
Ukuze uqonde umsuka wale nkinga, udinga ukwazi kancane ngamafutha kushokoledi.Ibhotela le-cocoa libalelwa ku-48% -57% wesisindo sikabhontshisi we-cocoa.Yinto eyenza ushokoledi ungancibiliki esandleni (uqinile ekamelweni lokushisa) uncibilike kuphela emlonyeni (uqala ukuncibilika ekushiseni komzimba).Ukubeka ucezu lukashokoledi olimini lwakho futhi uzizwe uncibilika kancane kancane emlonyeni wakho kungenye yezimfanelo eziyenga kakhulu zikashokoledi, konke sibonga ibhotela likakhokho.
Ibhotela likakhokho liyi-polymorphic, okusho ukuthi, ngaphansi kwezimo ezihlukene zokuqiniswa, lakha izinhlobo ezahlukene zamakristalu, okungenzeka azinzile noma angazinzile.Amakristalu azinzile apakishwe eduze futhi anamaphuzu ancibilikayo aphezulu kunamakristalu angazinzile.Ushokoledi kufanele siwufumise kahle ukuze kuthi uma usuwunambitha usabushelelezi ngaphandle futhi uthambe ngaphakathi njengoba siwenza.
Ibhotela likakhokho i-polymorph, ekhonjwa njengenamafomu amakristalu angu-5 ahlukene 1, y (Gamma) uhlobo, olwakhiwe ukupholisa okusheshayo ezingeni lokushisa eliphansi.Iwuhlobo lwecrystal olungazinzile ngokwedlulele, futhi indawo yalo yokuncibilika icishe ibe ngu-17°C2, uhlobo (Alpha), uhlobo lwe-y lungashintsha ngokushesha lube uhlobo, indawo yalo yokuncibilika iphakathi kuka-21~24°C, kodwa kancane kancane ishintsha ibe ngu-B. I-'crystal form 3, B' (Beta-prime), inezinhlobo ezimbili ze-crystal B'1 kanye ne-B'2, indawo yokuncibilika ye-B'2 crystal form iphakathi kuka-27 no-29°C.
4. I-Bi crystal form, indawo yayo yokuncibilika icishe ibe ngu-33C.IFomu B' lishintsha kancane libe yiFomu B
Ifomu B liwuhlobo lwekristalu oluzinzile kakhulu, futhi indawo yalo yokuncibilika icishe ibe ngu-34 ~ 35°C.
Ngaphezu kwalokho, abanye abantu bakholelwa ukuthi amakristalu cocoa bhotela babe 6 amafomu crystal, emelelwa izinombolo 1 ~ 6, futhi amaphuzu ukuncibilika kulezi zinhlobo 6 yilezi: 173 23 3% 25 5% 265% 33 836.4 °.Amafomu ekristalu 1 kuya ku-4 ngokuyisisekelo afana no-1 kuya ku-4 kumafomu ekristalu amahlanu angenhla, futhi wonke angamafomu ekristalu angazinzile.Umehluko wukuthi ifomu lesihlanu le-crystal B liyifomu lekristalu elizinzile kakhulu elinomthethonqubo ojwayelekile wokushisa.izoshintsha kancane kancane ibe yikristalu yesithupha ezinzile.
I-Tempering iwukuqinisekisa ukuthi ibhotela le-cocoa nebhotela le-cocoa-like lakha ifomu lekristalu elizinzile kakhulu, bese lipholile ngendlela efanele ukuze ushokoledi ube nokucwebezela okuhle futhi ungabi mhlophe isikhathi eside.
Ngokuvamile indlela yokushisa ushokoledi ihlanganisa izinyathelo ezilandelayo
1. Ncibilikisa ushokoledi ngokuphelele
2. Kuphole endaweni yezinga lokushisa elicwebezelayo
3. Khiqiza i-crystallization
4. Ncibilikisa amakristalu angazinzile
I-Melanger
Esigabeni sokushisa, ushokoledi uyashiswa, upholiswe bese ushiswa kabusha ngobumnene ekushiseni okunembile ukuze uthole amakristalu azinzile ebhotela likakhokho.Ngale ndlela, ungathola ukubukeka okubushelelezi nokucwebezelayo lapho kuqina, futhi umlomo ulungile, futhi usengakwazi ukuzwa umsindo opholile lapho uphula ibha kashokoledi.
Emkhiqizweni wangempela, izinga lokushisa likashokoledi ocolisisiwe livame ukuba ngaphezu kwama-45, futhi izinga lokushisa likashokoledi ogcinwe lifudumele ethangini lokufakelwa liphakathi kuka-40 no-45, futhi akukho crystallization yanoma yimaphi amafutha.Ngakho-ke, isigaba sokuqala sokushisa ukukhipha ukushisa okubucayi okuthinta i-crystallization yamafutha, okungukuthi, ukupholisa ushokoledi mass kusuka ku-40 kuya ku-50 kuya ku-32 ngokupholisa.Esigabeni sesibili sokulawulwa kwezinga lokushisa, izinto ziyaqhubeka nokuphola kusukela ku-32 ° kuya cishe ku-27 ° C, futhi uwoyela uqala ukwakha ifomu lekristalu le-B elizinzile kanye nefomu lekristalu elithi B "elingazinzile. Isigaba sesithathu sokulawulwa kwezinga lokushisa yisigaba sokugcina ukulawulwa kwezinga lokushisa, owaziwa nangokuthi Esigabeni sokubuyiselwa kwezinga lokushisa, izinga lokushisa lempahla likhuphuka lisuka ku-27 liye ku-30 ~ 32. Inhloso yokubuyisela ukuncibilikisa ifomu le-crystal B elingazinzile ngokuphindaphindiwe ngokushisa, lishiya ifomu le-crystal B elizinzile kakhulu.
Izinga lokushisa lingalungiswa ngesandla, kodwa izinga lokushisa kufanele libe elinembile.Ukukhethaumshini wokushisa ushokolediokulawula ngokunembile izinga lokushisa kuya kumehluko wezinga lokushisa ongaphansi kuka-±0.2 kungakusiza kahle kakhulu.Ukushisa kwamashokoledi ahlukene nakho akuhambelani ngokuphelele:
