如何处理酒精生产过程中结垢问题的探讨

Investigation on the Treatment of Mash Deposition in Alcohol Production

发酵成熟醪在输送、换热、蒸馏过程中,尤其在蒸馏时微溶或可溶物质浓度不断增加,其浓度超过其溶解度达到过饱和状态后,便会在设备内表面析出而形成醪垢,会造成换热器、蒸馏塔(醪塔)结垢堵塞,影响生产。对发酵过程醪垢成分、醪垢的成因进行分析,提出醪垢防治的措施和清洗办法。

Mash deposition usually formed on the inner surfase of the equipments during the transportation, heating exchange and distillation of fermented mash especially when soluable substances concentration kept increasing in the distillation and their concentration finally excessed their solubility and became oversaturated and finally formed precipitation. Mash deposition would block heating exchanger and distilling tower and seriously damage normal production. In this paper, the compositions and the formation of mash deposition were analyzed and the relative prevention measures of mash deposition formation and cleaning methods of mash deposition were put forward. （Tran. by YUE Yang ）
