甘蔗糖蜜酒精生产污垢控制最佳工艺点及污垢控制方法

选择甘蔗糖蜜酒精生产中蒸馏前多个工艺位点，采用重力分离法(稀释糖液静置、发酵醪底排污、机械离心)与添加化学助剂重力分离法对甘蔗糖蜜酒精生产物料进行除垢处理。测定除垢实验中物料及污垢的理化参数，以表观污垢、钙镁总量、硫酸盐总量为依据评价除垢效果，分析除垢特点。通过各工艺点各种控制方法的表观污垢去除率，进行甘蔗糖蜜酒精生产蒸馏前除垢最佳工艺点和方法的分析，提出甘蔗糖蜜酒精生产污垢控制除垢技术方案。

Optimal Process Points and Methods for Fouling Control in Alcohol Production from Sugarcane Molasses

This paper describes the selection of multiple process points before the distillation stage in alcohol production from sugarcane molasses,use of gravity separation methods(diluted molasses standing settlement,fouling removal at the bottom of the fermentation tank,mechanical centrifugationl) and gravity separation methods with the addition of chemical additives to perform antifouling processing on materials in alcohol production from sugarcane molasses.Physical and chemical parameters such as apparent fouling,total calcium magnesium and total sulfate were measured on materials and fouling to assess fouling removal effectiveness and characteristics.Based on apparent fouling removal rate by various control methods at various process points,optimal process points and methods for fouling removal were analyzed and technical protocols for fouling control and removal in alcohol production from sugarcane molasses were proposed.
