Method for the continuous thermal hydrolysis of sludges containing organic matter, said method comprising the steps of: simultaneously injecting pressurized steam (100) into said sludges and mixing said sludges with said steam by means of a dynamic mixer-injector (4) so as to obtain a single-phase mixture, conveying said single-phase mixture towards a tube reactor (4) under pressure and bringing about the plug flow of this mixture into said reactor for a retention time that is sufficient and at a temperature that is sufficient to enable the thermal hydrolysis of the organic matter present in said sludges, cooling said single-phase mixture at its exit from said tube reactor to a temperature enabling the subsequent digestion of the hydrolyzed organic matter that it contains, depressurizing said cooled single-phase mixture. |
