Abstract: The system (100) comprises a heating element (2) and a cooling element (3) to heat and/or cool the organic mass, a pump to convey a medium such as a fluid into a circuit between the heating element and the cooling element, a throttle (9) functionally provided between the heating and cooling elements, and a relaxation tank (10) provided below the throttle, where heat exchangers, in which the heat is exchanged between the organic mass and the medium, are provided as the heating element and cooling element. The organic mass and the medium in the heat exchanger are separated from each other. The system (100) comprises a heating element (2) and a cooling element (3) to heat and/or cool the organic mass, a pump to convey a medium such as a fluid into a circuit between the heating element and the cooling element, a throttle (9) functionally provided between the heating element and the cooling element, and a relaxation tank (10) provided below the throttle, where heat exchangers, in which the heat is exchanged between the organic mass and the medium, are provided as the heating element and cooling element. The organic mass and the medium in the heat exchanger are separated from each other. A relaxation tank valve connects itself to the relaxation tank and is designed to regulate the pressure in the relaxation tank. A hydrolysis reactor for the organic mass is functionally provided between the heating element and the throttle, and is an indirect heat exchanger, which is flowed through by an externally heated warming agent. A storage unit for the organic mass is functionally provided between the hydrolysis reactor and the throttle. An additional cooling element is functionally provided between the hydrolysis reactor and the throttle and is thermally coupled with the circuit of the medium using a first additional branch. An additional heating element is functionally provided between the heating element and the hydrolysis reactor and is thermally coupled with the circuit of the medium using the first additional branch. The passage through the first additional branch is regulated using a heating mixer valve. A further pump for the organic mass is functionally provided above the heating element. A condensation tank for the organic mass is functionally provided below the cooling element, where a condensation tank gas valve is provided to regulate the discharge of the gaseous phase of the organic mass from the condensation tank, so that the gaseous phase and the flowable components of the organic mass are separately discharged. A condensate cooling element is provided below the condensation tank, is designed to cool the organic mass and is coupled with the heating element and the cooling element using a second additional branch of the circuit of the medium, where a cooling mixer valve is provided and designed to regulate the distribution of the medium to the cooling element and the condensate cooling element. A relaxation tank gas valve is provided to discharge the gas from the relaxation tank and to supply the gas to the condensation tank. A recirculation passage for the organic mass is provided with a return valve, which is designed to regulate the flow-rate of the recirculation passage. An independent claim is included for a method for the thermal hydrolysis of organic mass.
