MUMBAI, India, Oct. 26 -- Intellectual Property India has published a patent application (202611113260 A) filed by Chandigarh University on September 22, 2026, for Stabilized Anaerobic Digestion Reactor With Intermittent Low-Shear Mixing.
Inventors include Aldrin Kudakwashe Shayamano; and Gurpreet Singh Sokhal.
The application for the patent was published on October 23, 2026, under issue no. 43/2026.
Abstract: The present invention relates to a stabilized anaerobic digestion reactor configured for conversion of organic biomass into methane-rich biogas, particularly rapidly fermentable and high-sugar biomass. The reactor comprises a sealed anaerobic digestion vessel having a feed inlet, digestate outlet, low-shear mixing mechanism, temperature regulation system, and gas collection assembly. The low-shear mixing mechanism comprises an agitator coupled to a geared drive motor and is configured to promote bulk movement of biomass while minimizing turbulence and mechanical shear. The agitator operates in intermittent on-off cycles comprising mixing intervals and quiescent digestion intervals, thereby reducing continuous mechanical agitation and associated energy consumption while supporting stable methanogenic activity. In certain embodiments, the reactor further comprises internal baffles or partitions for providing flow zoning within the digestion vessel. The reactor provides improved digestion stability, reduced acidification and scum formation, consistent methane production, and suitability for small-scale and decentralized biogas applications
