白酒瓶内沉淀物的分析与解决措施

摘要

在白酒生产过程中随着温度和酒度的变化导致难溶性物质出现过饱和状态析出沉淀,沉淀形状呈针状、片状、粉状、絮状等不同形貌,颜色有乳白色、灰白色、淡黄色、棕色、蓝黑色、绿色等。我们通过对成品白酒中晶体状沉淀的成因探析,定性分析了白酒中晶状沉淀的产生是由于加浆水硬度过大,所含的Ca2+和SO2-4形成白色晶体状沉淀CaSO4·2H2 O,并提出了相应的预防措施,改进生产工艺,防止白酒中沉淀物的析出以提高白酒质量。%The reason of crystalline precipitate in liquor was discovered through investigation. A crystal precipitation was the formation of CaSO4 ·2H2 O when the concentrations of Ca2+and SO2-4 exceeded the concentration plot constant. In view of the properties and the formation mechanism of precipitate, the relative prevention measures were applied to eliminate the precipitate and to improve liquor quality.
