Reference numerals 10, 10a ... Are paddle type main stirring blades having the highest stirring efficiency, which are formed by obliquely providing two flat blades 11 and 11a having a centrifugal effect.
0, 10a ... are fixed in the fermenter 1 in three stages below the central portion of the main stirring shaft 7, and the main stirring blades 10a in the middle stage are attached 90 degrees in phase to the main stirring blades 10 in the upper stage. The main stirring blade 1 in the lower stage is different from the main stirring blade 10a in the middle stage.
Install 0b so that they are 90 degrees in phase and cross each other.
Has been.

In this embodiment, the main stirring blades 10 and 10a
The main stirring shaft 7 is fixed in three stages, but the main stirring blades 10, 10a fixed to the main stirring shaft 7 may be fixed in two or more stages.

Further, in the vicinity of the raw material inlet 4 on the inner side of the fermentation tank 1, a baffle plate 12 is directed toward the center of the fermentation tank 1 in order to prevent a vortex flow caused by stirring and to enhance stirring efficiency.
Moreover, a space is provided between the fermenter 1 and the side wall of the fermenter 1, and the fermenter 1 is vertically fixed to the side wall, and a gas blowing pipe 13 capable of blowing gas from the outside is vertically fixed.

Numeral 14 is a trump that makes it easy to move up and down from the raw material inlet 4 when the fermenter 1 is put in and out for the purpose of inspection or cleaning. The treads 15, 15a of the trump 14 are fixed to the side wall of the fermenter 1. At the same time, the ramp 14 is fixed to the baffle plate 12 and the gas injection pipe 13.

Reference numeral 16 is a coupling, and 17 is a sampling port.

Next, the operation of the fermentation apparatus for liquefying rice liquor and moromi according to the present invention will be described. The rice liquefied liquid , koji and liquor are put into the fermentation tank 1 through the raw material inlet, and the driving unit 8 is operated to operate the main unit. The stirring blades 10, 10a ... Are rotated, gas is blown from the gas blowing pipe 13, and the jacket portion 3
The fermentation temperature is maintained by passing hot and cold water through the heating / cooling nozzles 2, 2a.

The liquid mixture of rice liquefied liquid , koji and liquor is sheared and mixed by the centrifugal effect of the paddle type main stirring blades 10, 10a, and flows outward, and flows upward in the outer peripheral portion of the fermentation tank 1. Then, it is swirled as a whole and stirred and mixed,
The granular material and the mixed solution are sheared and efficiently flow in the fermentation tank 1 to carry out stirring and mixing while maintaining uniformity throughout the fermentation tank 1.

The flow of the mixed solution caused by the stirring is obstructed by the baffle plate 12 to cause convection, thereby preventing a vortex flow, and in the space between the baffle plate 12 and the side wall of the fermentation tank 1, the tread plate 15 of the trump 14 is provided. , 15a ... are laterally arranged, the flow around and behind the baffle plate 12 is improved, and the gas from the gas injection pipe 13 is supplied at the center of the convection stirring, so that the entire mixed liquid is made uniform.
The temperature is adjusted and the stirring efficiency is improved.

In addition to the above-mentioned function, the turret 14 saves the trouble of putting it in and out of the fermenter 1 at every inspection or cleaning.

Further , the main stirring blades 10, 10a ...
Since it is provided in a staggered shape, it provides stable water throughout.
Since the force balance is maintained and the tip portion of the main stirring shaft 7 is received by the bearing portion 9, runout due to rotation of the main stirring shaft 7 during stirring and mixing is prevented, and the bearing portion 9 is also supported.
Is detachably attached to the tip end of the main stirring shaft 7, so that the maintenance of the bearing 9 can be performed by removing the inspection port 6 in which the bearing 9 is fixed from the processing liquid outlet 5.
