Kutheni ufuna umatshini wokuthambisa ngetshokholethi?

Ibhotela ye-cocoa iqulethwe ngeentlobo ze-acids ezinamafutha, kwaye umlinganiselo wokubunjwa kwayo ubangela ngokuthe ngqo ukuhlukana kwamanye ama-oyile aqinileyo kunye namafutha.Ibhotolo yecocoa ikhona kwifom yecrystalline, kwaye iifom zecrystalline zinemilo eyahlukeneyo kunye nobukhulu obuhlukeneyo kumaqondo obushushu ahlukeneyo, uphawu olwaziwa ngokuba yipolymorph.thinaicrystallization.NaziIintlobo zekristale ezi-4ibhotolo yekoko:

I-γ-uhlobo lwekristale: Indawo yokunyibilika yi-16 ~ 18 ° C, kwaye iguqula ibe yi-α-uhlobo malunga nemizuzwana ye-3.Ayizinzanga kakhulu kwaye kunzima ukuyisebenzisa, ngoko ke ayihoywa ngokuthe ngqo.

I-crystals yohlobo lwe-α (uhlobo lwe-I kunye nohlobo lwe-II): Indawo yokuncibilika yi-17 ~ 23 ° C, kwaye iguqula ibe yi-crystals yohlobo lwe-β' ngeyure enye kwiqondo lokushisa.I-soft texture, i-crumbly, kulula ukuyinyibilika ayifanelekanga ukusetyenziswa.

I-crystal yodidi lwe-β (uhlobo lwe-III kunye nohlobo lwe-IV): indawo yokunyibilika yi-25 ~ 28 ° C, kwaye iguqula ibe yi-crystal yodidi lwe-crystal kwiqondo lokushisa kwinyanga enye.I-texture iqinile, ayi-brittle, kwaye inyibilika lula.

Iikristale zohlobo lwe-β (uhlobo lwe-V kunye nohlobo lwe-VI): Indawo yokunyibilika yi-33 ~ 36 ° C, kwaye ukuthungwa lukhuni kwaye kuncinci.Phakathi kwazo, i-crystal yohlobo lwe-V yeyona nto ifanelekileyo yomgangatho ophezulu wesakhiwo, ngenxa yokuba izinzile kwaye inembonakalo ekhanyayo;olona hlobo lwekristale oluzinzile lwe-VI kunye neyona ndawo iphezulu yokunyibilika inamasuntswana arhabaxa, incasa embi, kunye neendawo zeoyile ziya kubonakala phezu komhlaba.Emva kwexesha elide, i-chocolate surface iya kubonakalahi-oafrost.

Ukongeza kwiikristale zohlobo lwe-V, ezinye iikristale azifani ngokufanelekileyo, ziswele amandla okunxibelelana ngokufanelekileyo, zinezakhiwo zangaphakathi ezikhululekileyo nezibuthathaka kunye nenethiwekhi yamafutha angalinganiyo, engakwaziyo ukugcina imeko ezinzileyo, yenza itshokolethi egqityiweyo ibe brittle kwaye ibe buthuntu, kwaye kude kuqatsele.iyaqina, okanye inyibilike ngaphezu kobushushu begumbi.Ubume be-crystal ene-V yi-Hexagon ene-hexagonal, enokuthi ihlelwe ngokufanelekileyo kwaye idibaniswe ukuze yenze ulungelelwaniso oluqinileyo, ngaloo ndlela yenza isakhiwo setshokolethi sizinzile kwaye sinzima.Le yindima ephambili yolawulo lobushushu.

Injongo yokuthambisa itshokholethi kukuthambisa ibhotolo yekoko ngaphambili kwitshokholethi, nto leyo ibalulekileyo ekuqhubeni itshokolethi.Ngexesha lenkqubo yokufudumala, ibhotela ye-cocoa kwitshokolethi yenza i-polymorphous Crystallization ezinzileyo ye-polymorphous.Imveliso egqityiweyo ke ngoko iya kuba nombala oqaqambileyo kunye nobunzima obunzima.Ikwanceda itshokholethi ukuba inciphe ngexesha lokupholisa, nto leyo eyenza kube lula ukuyisusa.

Ukuba i-tshokoleta iqala ukupholisa kwiqondo lokushisa elisebenzayo emva nje kokunyibilika (40-45 ° C), umkhiqizo ogqityiweyo awuyi kuba nombala oqaqambileyo.Ukuba uthatha ixesha lokupholisa ngokufanelekileyo itshokolethi kwiqondo lokushisa elichanekileyo lokusebenza, uqinisekile ukuba uya kufumana ukugqiba okufunayo.

Oomatshini bokuthambisa ibhetshi ye-LST kunye noomatshini bobushushu obuqhubekayo bayilwe ngokwemeko yecrystallization yebhotolo yekoko.Impembelelo yokulungiswa kweqondo lokushisa ilungile, ulawulo lwe-PLC, kunye nobushushu bokulungelelaniswa kobushushu bunokusetwa ngokweemveliso ezahlukeneyo, umzekelo, itshokolethi emnyama 45-50 ° C ukuya kwi-28-29 ° C, ibuyele kwi-30-31 ° C, itshokolethi yobisi. 45-48 ° C ukuya 27- 28 ° C umva 29-30 ° C, itshokolethi emhlophe 45-48 ° C ukuya 26-27 ° C ubuyele kwi-28-29 ° C.Iindaba ezilandelayo zazisa ngoomatshini bokuthambisa ibhetshi kunye noomatshini bobushushu obuqhubekayo ngokweenkcukacha.
