PROBLEM TO BE SOLVED: To provide a mixing vessel being a cylindrical vessel capable of storing a large amount of powder and also capable of mixing the whole powder at a time. SOLUTION: A corner shielding wall 2 covering the circumferential corner part 11 of a cylindrical vessel 1 opens part of a cylindrical vessel 1 from the bottom to a certain height. A rotating bearing wheel 3 revolving through a ring having a triangular cross section formed by the circumferential corner part 11 and the corner shielding wall 2 and a rotating driving part 4 mounted at the center of the upper cover downward are connected by a flexible rotary shaft 5 provided with a ribbon-shaped blade 6. By the rotation of the flexible rotary shaft 5, the rotating bearing wheel 3 also revolves along the wall surface of the vessel wall and causes three basic motions of rise, horizontal movement and gravity falling to a powder to mix the whole powder. Time, processes and a place are saved since the temp. of the vessel is regulated and fermentation, aging, reaction, drying, etc., are executed during storage by properly injecting water, air or chemical through the flexible rotary shaft 5.
