なかつた。 Such fermentation generally involves inoculating fermentation bacteria that produce the target product into a medium containing a carbon source such as molasses or sugar, a nitrogen source such as ammonium sulfate, an inorganic salt such as monopotassium phosphate or sulfuric acid, and other organic nutrients. This is done in a fermentation tank with aeration and stirring. In order to check the properties of this fermented liquid one after another, various sensors such as a PH meter, dissolved oxygen electrode, and ammonia concentration meter are inserted into the fermentation tank. These sensors operate continuously or at predetermined time intervals to record or display each item to notify workers of abnormalities in order to facilitate fermentation, but these sensors are used only during the final stage of fermentation. Since the sensor is inserted into the fermentation tank until the fermentation process is complete, there is a marked tendency for bacterial cells and precipitated denatured proteins to adhere to the sensor during fermentation. Functionality was impaired. In addition, in order to remove such attached bacterial bodies, it is difficult to pull out the sensor from the fermentation tank during fermentation and clean it because the sensor is attached to the side wall of the fermentation tank so that it is immersed in the fermentation liquid. This is not possible, and is also undesirable as it may contaminate bacteria. Therefore, once bacterial cells etc. have adhered, there is no other countermeasure than to continue fermentation in the adhered state.

ている。 The present invention aims to maintain the normal functions of various sensors and to ensure smooth progress of the fermentation process by removing bacterial cells, denatured proteins, etc. attached to such sensors during fermentation and washing them. It is an object.

ることにより、上記目的を達成したものである。 In the present invention, a nozzle is provided facing and close to the tip of a sensor inserted into a fermentation tank, and a brush body that can be rotated by the flow pressure caused by the stirring flow of the fermentation liquid is attached to the tip of the sensor. During fermentation, the tip of the sensor is constantly rubbed with the brush body, and when there is deposits on the tip of the sensor, a nozzle is used to inject steam onto the tip of the sensor. The above objectives have been achieved.
以上、図面を参照して本発明の一実施例を具体
的に説明する。 Hereinafter, one embodiment of the present invention will be specifically described with reference to the drawings.

を消泡せしめるものである。 In Fig. 1, the fermentation tank consists of a main body 2 and a lid 3 screwed together by a flange 1, and various pipes such as a gas outlet, a culture medium supply pipe, an alkali or acid supply pipe are installed on the top of the lid 3. An opening 4 is provided for introduction, and a motor 5 is mounted on the upper central surface of the opening 4, and a main shaft 5a of the motor 5 is suspended within the main body 2. On the other hand, a cooling jacket 6 is attached to the outer wall of the main body 2, and a ring spargeer 7 for supplying air is provided at the lower end of the inside, and is attached to the main shaft 5a suspended from the motor 5 at appropriate intervals. An attached stirring blade 5b, such as a paddle-shaped stirring blade, is immersed in the fermentation liquid, and a foam cutting blade 5c installed above the main shaft 5a is provided above the fermentation liquid. The agitating blade 5b rotates to flow and stir the fermented liquid to make the fermented liquid uniform, and the foam cutting blade 5c defoams the foam generated by fermentation.

酵中におけるセンサの洗浄が可能となる。 In such a fermentation tank, a sensor 8 such as a PH meter or a dissolved oxygen electrode is appropriately attached to the middle part of the side wall of the main body 2, and the tip of the sensor 8 is inserted through an opening penetrating the side wall of the main body. Immersed in fermentation liquid. A nozzle 9 for steam injection is provided in the main body 2 adjacent to the sensor 8. That is, this nozzle 9 is provided close to the tip of the sensor 8 with its opening facing the tip of the sensor 8, and is fed into a pipe 9a attached to the side wall of the main body 2. The steam is injected from the opening of the nozzle 9 toward the tip of the sensor. Therefore, the tissues of bacterial cells, denatured proteins, etc. attached to the sensor are destroyed by the heat and jet flow of the steam, and are simultaneously scattered, thereby making it possible to clean the sensor during fermentation.

る。 Such injection of steam does not need to be carried out continuously, but may be carried out at any time depending on the time when bacterial cells etc. have attached. If carried out continuously, it often has adverse effects on the fermentation liquid such as temperature rise and dilution, and fermentation may not take place due to changes in its properties. This is due to the fact that it is possible to suppress the change in the amount to an extremely low level, and furthermore, its removal can be sufficiently achieved by carrying out the removal at any time during the period of adhesion. The injection amount, injection speed, etc. of the steam are selected according to the attached bacterial cells and the like to the minimum extent necessary to remove the attached matter.
さらに、ノズル９とセンサ８の先端部との間隔
も、蒸気噴射による除去が可能な範囲内で設定さ
れる。 Furthermore, the distance between the nozzle 9 and the tip of the sensor 8 is also set within a range that allows removal by steam injection.

するものである。 Further, as shown in detail in FIG. 2, the brush 11 of the brush body 10 is provided so as to rub against the tip of the sensor 8. That is, this brush body 10 has a brush 1 implanted on the upper surface of the rotating shaft 12.
1, a blade 14 attached to the tip of a connecting rod 13 extending laterally from the rotating shaft 12, and a support part 15 that supports the rotating shaft 12 and is attached to the bottom or side wall of the main body 2, and as appropriate. Or preferably, a stirring blade 5b immersed in the fermentation liquid in the main body 2
With the brush 11 in contact with the tip of the sensor 8, the blades 14 are rotated by the fluid pressure of the agitated fermentation liquid, thereby causing the brush 11 to rotate.
The brush 11 also rotates and the brush 11 scrapes the tip of the sensor 8.

であればよく、その形状は問わず、例えば、第３
図イに示すように輪状板１６の上面に植設された
ものでも、同図ロのように筒体１７上に植設され
たものであつてもよい。 Therefore, in the case of this embodiment, the brush 11 constantly rubs the tip of the sensor 8 during fermentation, making it difficult for bacterial cells to adhere. Furthermore, even if bacterial cells or the like adhere to the surface, they can be dissolved by injecting steam from the nozzle 9, so that cleaning is possible. Furthermore, the brush body can be rotated without using external driving force.
It also has the advantage of being economical because it utilizes the fluid pressure caused by the stirring flow of the fermentation liquid inside the tank.
Any device may be used as long as it rotates due to the fluid pressure of the brush fermentation liquid, and its shape does not matter.
It may be implanted on the upper surface of the annular plate 16 as shown in Figure A, or it may be implanted on the cylindrical body 17 as shown in Figure B.

することができる。 Furthermore, since the sensor can be cleaned with steam at any time, cleaning during fermentation is possible without having to remove the sensor, which is efficient. Further, since steam is used for washing, there is no possibility that bacteria will be mixed into the fermentation liquid, and a decrease in yield due to the contamination of bacteria can be prevented.

る。 As described above in detail, according to the present invention, by providing a brush body and a nozzle that injects steam, it is possible to prevent bacteria, denatured proteins, etc. attached to various sensors from adhering to the sensors, and Even if it adheres, it can be easily removed, so the sensor can be used with good sensitivity at all times without interrupting fermentation.
