Cocoa batala amapangidwa ndi mitundu yosiyanasiyana yamafuta acid, ndipo kuchuluka kwake komwe kumayambitsa mwachindunji kumapangitsa kusiyana ndi mafuta ena olimba ndi mafuta.Batala wa Cocoa amapezeka mu mawonekedwe a crystalline, ndipo mawonekedwe a crystalline amakhala ndi maonekedwe ndi makulidwe osiyanasiyana pa kutentha kosiyana, khalidwe lotchedwa polymorph.ifecrystallization.Pali4 mitundu ya kristalomafuta a cocoa:

γ-mtundu wa kristalo: Malo osungunuka ndi 16 ~ 18 ° C, ndipo amasandulika kukhala α-mtundu pafupifupi 3 masekondi.Ndi yosakhazikika kwambiri komanso yovuta kuigwiritsa ntchito, chifukwa chake imanyalanyazidwa mwachindunji.

Makristasi amtundu wa α (mtundu wa I-mtundu ndi II): Malo osungunuka ndi 17 ~ 23 ° C, ndipo amasintha kukhala makhiristo amtundu wa β' mu ola limodzi kutentha.Maonekedwe ofewa, opunduka, osavuta kusungunuka si oyenera kugwiritsidwa ntchito.

β' mtundu wa krustalo (mtundu wa III ndi mtundu wa IV): malo osungunuka ndi 25 ~ 28 ° C, ndipo amasandulika kukhala kristalo wamtundu wa β kutentha kwa mwezi umodzi.Maonekedwe ake ndi olimba, osagwedezeka, ndipo amasungunuka mosavuta.

Makhiristo amtundu wa β (mtundu wa V ndi mtundu wa VI): Malo osungunuka ndi 33 ~ 36 ° C, ndipo mawonekedwe ake ndi ovuta komanso osasunthika.Pakati pawo, kristalo wa V-mtundu ndiye mawonekedwe abwino kwambiri apamwamba, chifukwa ndi okhazikika komanso owoneka bwino;kristalo wokhazikika kwambiri wa mtundu wa VI wokhala ndi malo osungunuka kwambiri amakhala ndi tinthu tating'onoting'ono, kukoma koyipa, ndi mawanga amafuta adzawonekera pamwamba.Patapita nthawi yaitali, chokoleti pamwamba adzaonekahchisanu.

Kuphatikiza pa makhiristo amtundu wa V, makhiristo ena amakhala osakhazikika, alibe mphamvu yolumikizirana bwino, amakhala ndi zida zotayirira komanso zofooka zamkati ndi netiweki yamafuta osagwirizana, omwe sangathe kukhalabe okhazikika, kupangitsa chokoleti chomalizidwa kukhala chosavuta komanso chopepuka, choyipa kwambiri.umalimba, kapena umasungunuka pamwamba pa kutentha kwa chipinda.Maonekedwe a kristalo wopangidwa ndi V ndi Hexagon ya hexagonal, yomwe imatha kukonzedwa bwino ndikuphatikizidwa kuti ikhale yolimba, motero kupanga mapangidwe a chokoleti kukhala olimba komanso olimba.Ili ndiye gawo lofunikira pakuwongolera kutentha.

Cholinga cha kutenthetsa kwa chokoleti ndikuyika batala wa cocoa mu chokoleti, zomwe ndizofunikira kwambiri pokonza chokoleti.Pa tempering ndondomeko, koko batala mu chokoleti ndipamene khola polymorphous Polymorphous Crystallization.Chotsirizidwa choterocho chidzakhala ndi mtundu wowala komanso mawonekedwe ovuta.Zimathandizanso kuchepa kwa chokoleti panthawi yozizira, zomwe zimapangitsa kuti zikhale zosavuta kuzisintha.

Ngati chokoleti iyamba kuzizira kutentha koyenera kugwira ntchito itangosungunuka (40-45 ° C), chomaliza sichidzakhala ndi mtundu wowala.Ngati mutenga nthawi kuti muziziritsa bwino chokoleti kutentha koyenera, ndiye kuti mukutsimikiza kuti mumaliza.

Makina otenthetsera a LST batch ndi makina osalekeza osalekeza amapangidwa molingana ndi mawonekedwe a batala wa koko.Kusintha kwa kutentha kumakhala bwino, kuwongolera kwa PLC, ndi kutentha kwa kutentha kumatha kukhazikitsidwa malinga ndi zinthu zosiyanasiyana, mwachitsanzo, chokoleti chakuda 45-50 ° C mpaka 28-29 ° C, kubwerera ku 30-31 ° C, chokoleti cha mkaka. 45-48 ° C mpaka 27- 28 ° C kubwerera ku 29-30 ° C, chokoleti choyera 45-48 ° C mpaka 26-27 ° C kutentha kwa 28-29 ° C.Nkhani yotsatira ikuwonetsa makina otenthetsera batch ndi makina otenthetsera mosalekeza mwatsatanetsatane.
