一种浓醪发酵酒精糟液固液分离方法

2016-03-27 22:57:16 杭州沃腾膜工程有限公司 已读
本发明涉及酒精、环保等领域,具体地说是将浓醪发酵酒精后产生的酒糟经膜过滤技术一次性固液分离,并将滤液全部作为投料水循环多次使用,从而解决酒糟污染的问题,将被动的处理变为主动有效的综合利用,达到降低酒精生产成本,保护环境的目的。本发明的优点在于:基本可以实现酒糟的零排放,有效的保护环境,并且大大减少了生产用水;采用膜过滤技术一次性固液分离成功,减少了设备投资,节约成本;滤液中本身含可利用成分,可以促进发酵,最终提高发酵醪酒精度,提高淀粉利用率,节约酒精生产成本。
权利要求(2)
1.一种浓醪发酵酒精糟液固液分离方法,其特征在于将浓醪发酵酒精后产生的酒糟直接经膜过滤技术一次性固液分离,并将滤液全部回用作为投料水使用,所用的膜过滤设备为陶瓷膜过滤设备,膜过滤的操作条件为:过滤孔径:0.2~2微米,过滤温度为30~98℃,工作压力0.08~0.2兆帕。
2.根据权利要求1所述的方法,其特征在于膜过滤的操作条件为:过滤孔径:0.2~2微米,过滤温度为60~90℃,工作压力0.1兆帕。
