FIELD: chemistry.
SUBSTANCE: group of inventions relates to biochemistry. A method and an apparatus for producing biogas from organic substances are disclosed. The method includes feeding a substrate into a container with a mixing mechanism, measuring rheological properties of the fermentation substrate in the region near impellers of the mixing mechanism. The measurement result is compared with a given value which is the desired value for a specific apparatus. The apparatus for producing biogas from organic substances comprises a container, a feeding system, a mixing mechanism, a sensor for measuring rheological properties of the fermentation substrate and a control unit.
EFFECT: larger amount of the converted fermentation substrate and the generated amount of methane gas.
