Experimental Design and Study of Shear Technology for Biomass Comminuting

To increase the security of energy supply, it is essential to search for utilization alternatives of renewable energy sources. The fermentation of organic material is more effective if the substrate is subjected to pre-treatment. In order to avoid toxic byproduct in the course of pre-treatment, a mechanical method was preferred. In this paper, the behavior of agricultural raw materials subjected to mechanical disintegration is examined. The pre-treatment of substrate was carried out with a comminuting machine which is normally used in industrial sewage fermenters in Hungary, but in agricultural biogas plants it has not been built in the technological process yet.
