PCM結晶監測系統在印度的全自動釜式蔗糖結晶生產線投入使用
1應用背景
mso-hansi-font-family:Arial;mso-bidi-font-family:Arial;font-size:10.5000pt;
mso-font-kerning:1.0000pt;">蔗糖作為食糖的主要成分,由一分子葡萄糖的半縮醛羥基與一分子果糖的半縮醛羥基縮合脫水而成,在食品及調味品等行業中有著十分重要的用途。蔗糖普遍存在于植物界的葉、花、莖、種子及果實中,甘蔗、甜菜及槭樹汁中的蔗糖含量尤為豐富。

mso-font-kerning:1.0000pt;">大多
font-size:10.5000pt;mso-font-kerning:1.0000pt;">采用蒸發結晶工藝。隨著結晶

mso-font-kerning:1.0000pt;">過程

mso-hansi-font-family:Arial;mso-bidi-font-family:Arial;font-size:10.5000pt;
mso-font-kerning:1.0000pt;">,
font-size:10.5000pt;mso-font-kerning:1.0000pt;">糖漿粘度不斷變大,使得結晶受擴散控制,
mso-hansi-font-family:Arial;mso-bidi-font-family:Arial;font-size:10.5000pt;
mso-font-kerning:1.0000pt;">從而
font-size:10.5000pt;mso-font-kerning:1.0000pt;">晶體生長緩慢
mso-hansi-font-family:Arial;mso-bidi-font-family:Arial;font-size:10.5000pt;
mso-font-kerning:1.0000pt;">;

mso-hansi-font-family:Arial;mso-bidi-font-family:Arial;font-size:10.5000pt;
mso-font-kerning:1.0000pt;">,
font-size:10.5000pt;mso-font-kerning:1.0000pt;">加之擴散
mso-hansi-font-family:Arial;mso-bidi-font-family:Arial;font-size:10.5000pt;

mso-hansi-font-family:Arial;mso-bidi-font-family:Arial;font-size:10.5000pt;
mso-font-kerning:1.0000pt;">,致使
font-size:10.5000pt;mso-font-kerning:1.0000pt;">體系中易發生二次成核
mso-hansi-font-family:Arial;mso-bidi-font-family:Arial;font-size:10.5000pt;
mso-font-kerning:1.0000pt;">現象
font-size:10.5000pt;mso-font-kerning:1.0000pt;">,導致終產品顆粒度分布大

mso-hansi-font-family:Arial;mso-bidi-font-family:Arial;font-size:10.5000pt;
mso-font-kerning:1.0000pt;">,
font-size:10.5000pt;mso-font-kerning:1.0000pt;">又導致體系粘度快速上升,進一步阻礙了結晶物料向晶面的擴散,使得體系小晶核進一步增加,粘度進一步增大,終導致產品收率降低。正是基于以上難點,
