DIGESTER WITH BIOGAS CONFINEMENT MEANS

摘要

The invention relates to a digester (30) for implementing a methanization process of organic waste (36) in order to produce a biogas and a digestate, wherein said digester includes a portion defining a tank (31) for containing said organic waste (36), said tank-forming portion including a removable agitator (32), and a roof-defining portion (33) for closing said tank-forming portion (31), said roof-forming portion (33) including a first portion (331) having an opening (34) formed therethrough for the passage of the agitator (32). According to the invention, the agitator includes confinement means (332, 61) for said biogas in order to maintain the biogas inside the digester (30) during the extraction and after the extraction of the removable agitator (32).
