摘 要: 本文研究了超声促进胶体聚沉作用,选用了具有代表性的原糖溶液和老抽酱油为研究对象,研究结果表明:适宜的超声参数能十分显著加速胶体的聚沉,为物理场手段除去胶体提供一个新的途径. In this paper, two typical colloidal systems (raw sugar solution and dark soy sauce) are treated by ultrasound, and the effect of ultrasound in colloidal coagulation and precipitation is studied, the results indicate that with suitable ultrasonic parameters the effect can be obvious. New way is provided for removing colloidal by physical field.
