Crystallization ntawm iav wine fwj yog nag lossis daus ntawm cov iav los ntawm iav lub cev, thiab cov tsos ntawm cov muaju hauv iav cawv fwj yog ib qho tsis xws luag hauv iav cawv fwj. Xws li qhov tsis xws luag tsis raug tso cai tshwm sim hauv kev tsim cov iav iav fwj. Yog li, dab tsi ua rau crystallization ntawm iav fwj thaum lub sijhawm tsim khoom?
Tus nqi ntawm cov iav nuclei daim ntawv. Hauv kev tsim cov iav fwj, tus naj npawb ntawm cov siv lead ua tshiab ntxiv rau hauv cov iav yaj hauv ib lub sijhawm yuav ua rau crystallization ntawm iav cawv fwj thaum lub sijhawm tsim khoom. Qhov hu ua nucleation kev loj hlob tus nqi yog hais txog cov kab ntawm cov siv lead ua kev loj hlob ib lub sij hawm, thiab cov siv lead ua kev loj hlob feem ntau yog qhia nyob rau hauv microns tsim ib feeb. Yog li ntawd, lub iav nucleus yog ib qho tseem ceeb cuam tshuam rau crystallization ntawm iav cawv fwj.
Txias tus nqi tswj cov iav yaj. Qee lub sij hawm hauv kev tsim cov iav fwj, yog tias qhov txias ntawm lub khob yaj yog tswj kom maj mam txo qhov kub thiab txias, thaum qhov kub thiab txias poob mus rau qee yam, lub khob cawv cawv yog qhov ua rau crystallization nyob rau lub sijhawm no. Feem ntau, qhov ntsuas kub no feem ntau yog hais txog qhov kub ntawm cov kua dej kom siab tshaj qhov kub thaum lub iav ua ib qho khoom, uas yuav tsum tau ua tib zoo saib xyuas qhov ntsuas kub kom tsim nyog thaum lub sij hawm tsim khoom kom txo tau qhov tshwm sim ntawm crystallization.
