ABSTRACT:
A possible counterflow of a fermenting solution (8) from a fermentation tank (1) into a heating medium supply pipe (2), which counterflow may be caused by a pressure difference arising between the inner space (7) of the tank (1) and the pipe (2) after the supply of a heating medium is finished, is prevented by making the pressure difference disappear with a check valve (6) connected to the pipe (2) in the direction from the inner space (7) of the tank (1) to the pipe (2).
