Therefore, it is necessary to activate the activity of microorganisms, but if fermentation progresses, the heat generated by fermentation may slow down the activity of microorganisms or even kill them. To prevent this, the medium must be cooled.

（考案が解決しようとする問題点）
ところが、上述の様に構成され作用する従来の
醗酵装置用温度制御装置に於いては、次に述べる
様な不都合を生じる。(Problems to be Solved by the Invention) However, in the conventional temperature control device for fermentation equipment constructed and operated as described above, the following disadvantages occur.
即ち、醗酵装置を使用するのに先立つて、醗酵

けられない。この為、滅菌状態時に、伝熱管内に
残留する水が加熱されて、この水の一部が蒸発す

熱損失が大きくなるだけでなく、水（水道水）中
に含まれる物質が次第に濃縮されてしまう。 That is, prior to using the fermentation device, the inside of the fermentation tank 2 is heated to a temperature of 120° C., for example, by a heating device (not shown).
The inside of this fermenter 2 must be kept in a sterile state by heating to about It is difficult to completely drain the water inside the heat transfer tube, and it is inevitable that water remains inside the heat transfer tube. For this reason, during sterilization, the water remaining in the heat transfer tube is heated and some of this water inevitably evaporates, which not only increases heat loss due to the loss of latent heat of evaporation, but also causes the water to evaporate. The substances contained in (tap water) gradually become concentrated.
水中に含まれる塩素イオンが濃縮された場合、
各管３，４，１０，１１を内面から腐食させる原
因となるだけでなく、その他の不純物がスケール

熱伝達が不良となつてしまう。 When chlorine ions in water become concentrated,
Not only does it cause corrosion of each tube 3, 4, 10, 11 from the inside, but if other impurities adhere to the inside of the heat exchanger tube 3 as scale, the water flowing inside the heat exchanger tube 3 and the outside of the heat exchanger tube 3 will be damaged. Heat transfer with the existing medium will be poor.
本考案の醗酵装置用温度制御装置は、上述の様
な不都合を何れも解消するものである。 The temperature control device for fermentation equipment of the present invention eliminates all of the above-mentioned disadvantages.
