Therefore, it is suitable for accommodating and stirring a large amount of marine products such as purple shellfish removed from the water intake and the drain in the power plant.

Further, the apparatus main body forming the accommodation space is formed by a peripheral wall formed in a U-shaped cross section and opened upward, and a pair of side surfaces provided at both ends of the peripheral wall. Therefore, by setting the length of the peripheral wall portion in the lateral direction to be long, the volume in the housing space can be increased. For this reason, in order to enlarge the accommodation space, the height dimension had to be set high, and like the conventional mixer in which the accommodation space is reduced in diameter as the accommodation space goes downward, The accommodation space can be easily expanded without increasing the pressure. Furthermore, since the surface area with respect to the accommodation volume is smaller than in the case where the accommodation space is formed in a triangular pyramid shape, the amount of heat radiation from the surface can be suppressed, and the heat retention can be improved. Therefore, it is possible to improve the survival environment of the microorganisms that decompose the organic matter, and it is possible to provide an agitator for treating the organic matter suitable for the decomposition treatment of the organic matter by the microorganisms.
