摘要: 电渗透脱水在豆制品加工中,特别是豆腐皮加工中的应用,正处在研究阶段。本文在传统的重力压榨的基础上,又分别采用直流电场电渗透以及不等占空比电场电渗透来研究豆凝乳的脱水效果。结果发现,与另外两者相比,不等占空比电场电渗透方法效果明显,而且,在一定范围内,电压越高,脱水效果越好。

Abstract: The electroosmotic dewatering method is a new typical technology in soybean productions , especially in bean curd skin.In this paper, we study the dewatering efficiency of tofu by using DC electroosmotic dewatering, different pulse-time electric fieldelectroosmotic dewatering and weight pressure. We found that compared to the others,the method of different pulse-time electric fieldelectroosmotic dewatering is the best. And what’s more,the dewatering efficiency will increase if we increase the voltage.

Key words: electroosmosis, dewatering, different pulse-time electric field, bean curd skin
