| Abstract | Periodic peristalsis is an effective intensification method in high solids enzymatic hydrolysis. But the change law of slurry physical properties was not fully understood in periodic peristalsis enzymatic hydrolysis (PPEH) at high solids. This leads to the limitation of its application. Therefore, we studied particle size, viscosity and yield stress changes under periodic peristalsis. The D50 decreased by 42.59% and the viscosity decreased from 290.5 to 0.63 Pa s within 2 h under periodic peristalsis. The yield stress decreased from 245.9 Pa to 8.6 Pa and the fluidity of slurry can be pumped. Furthermore, the relationship between its physical properties and enzymatic hydrolysis efficiency and energy consumption was analyzed. And a method of calculating periodic peristalsis energy consumption was proposed. The energy consumption of periodic peristalsis is one-ninth of the stirring by calculation. These results provided guidance for its industrial application. |
