Abstract

(57) [Summary] [Purpose] To prevent unreliable culture work from being performed without your knowledge. [Structure] The culture device body 3 is a culture tank 1 for storing a culture solution.
And adjusting device 2. The controller 4 controls the adjusting device 2 so that the culture device main body 3 performs a culture operation according to a predetermined program. The power failure recovery device 5 has a storage unit for storing the progress status of the program executed by the controller 4, and based on the progress status stored at the moment of occurrence of the power failure, the controller 4 after the power failure is recovered.
Thus, the culturing apparatus main body 3 is made to continue the culturing work. The cancel switch 6 stops the operation of the power failure recovery device 5.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The culture device according to the present invention is used to culture various microorganisms or plant cells.

[0002]

[Prior Art]

 In recent years, it has been widely practiced to culture various microorganisms and plant cells by using a culture device called a jar fermenter, a bioreactor or the like. When performing the culturing work, the above-mentioned microorganisms and plant cells are put together with the culture solution into the culture tank constituting the culture apparatus, and the temperature, oxygen concentration, nutrient concentration, PH value, etc. of the culture solution are maintained at desired values. At the same time, the above culture solution is stirred.

Since the culturing work often lasts for a long time (several days to several weeks), the work of maintaining the temperature, oxygen concentration, nutrient concentration, PH value, etc. of the culture solution at desired values is performed by a micro computer. Automatically by the built-in controller. That is, the culture device comprises a culture tank for storing the culture liquid, a culture device main body having an adjusting device for adjusting the culture liquid in the culture liquid to a desired culture condition, and the culture device main body is set in advance. A controller for controlling the above-mentioned adjusting device is provided in order to perform the culturing work according to the programmed program.

The adjusting device is provided in the culture tank, and controls the heater and the cooler based on signals from various sensors that detect the temperature, oxygen concentration, nutrient concentration, PH value, etc. of the culture solution. Control the sparger for blowing gas into the culture solution, control the amount of nutrients injected, and control the amount of acid and alkaline solution injected.

Since the culture device main body including the adjusting device and the controller operate based on electricity supplied from the commercial power source, the desired culture work cannot be performed in the event of a power failure, but the culture work remains the same even after a short power failure. In order to prevent the work that was interrupted and wasted until then being wasted, the culture device has been equipped with a power failure recovery device.

[0006] The power failure recovery device of the culture device has a storage unit for storing the progress status of the program executed by the controller, and based on the progress status stored at the moment of occurrence of the power failure, The controller causes the main body of the culture apparatus to continue the culture work.

[0007]

[Problems to be solved by the device]

 However, in the case of a power failure recovery device built into a conventional culture device, if a power failure occurs and then recovers, the remaining programs will be executed after the recovery regardless of the time (length) of the power failure. It was restarting as it was.

On the other hand, if the power failure time is long and the temperature, oxygen concentration, nutrient concentration, PH value, etc. of the culture solution in the culture tank deviate greatly from the desired values during that period, the culture work is restarted. However, not only will it not be possible to obtain satisfactory culture results, but it will also cause erroneous experimental data.

If a power failure occurs during the day when there are researchers, it can be judged whether or not reliable culture work can be performed when the culture work is restarted. If it occurs and the time is long, the culturing work leading to unreliable data may be performed unknowingly as described above.

The culture device of the present invention has been devised in view of such circumstances.

[0011]

[Means for Solving the Problems]

 The culture apparatus of the present invention is configured as shown in FIG. 1, like the conventional culture apparatus described above. The culture device body 3 has a culture tank 1 for storing the culture liquid, and an adjusting device 2 for adjusting the culture liquid in the culture liquid 1 to a desired culture condition. Further, the controller 4 controls the adjusting device 2 so that the culture device main body 3 can perform the culture work according to a predetermined program. Further, the power failure recovery device 5 has a storage unit for storing the progress status of the program executed by the controller 4, and based on the progress status memorized at the moment when the power failure occurs, the controller after the power failure is recovered. 4, the culture apparatus main body 3 is caused to continue the culture work.

Further, the culture device of the present invention is characterized in that a cancel switch 6 for stopping the operation of the power failure recovery device 5 is provided. It is needless to say that the switch for selecting whether to operate the power failure recovery device 5 is a kind of the cancel switch 6.

[0013]

[Action]

 The culture device of the present invention configured as described above operates as shown in FIG. That is, when the cancel switch 6 is not turned on (is not operated) depending on the situation such as the presence of researchers during the daytime, the power failure recovery device 5 is activated and the power is restored like the conventional device. In this case, based on the progress status stored at the moment of the power failure, the controller 4 causes the culture apparatus body 3 to continue the culture work after the power failure is restored.

On the contrary, when a power failure occurs when the cancel switch 6 is turned on (operated) at night, depending on the situation where there are no researchers, the power failure recovery device 5 does not operate and the power failure is recovered. Even in this case, the culturing work by the culturing apparatus body 3 is not continued.

[0015]

[Effect of the device]

 Since the culture device of the present invention is configured and operates as described above, unreliable culture work will not be performed without knowing it, and erroneous data will be confused without knowing it. Can be prevented.
