Culture apparatus
View Patent ↗A culture apparatus which is capable of shortening sterilization time includes a gas concentration measuring sensor, pipes connected to a gas concentration measuring device and every corner of a cultivating chamber, and a sterilizing gas generator that supplies sterilizing gas into a cultivating chamber and atomizes a sterilizer solution (oxygenated water) by means of an ultrasonic vibrator. The culture apparatus further includes an ultraviolet lamp that irradiates gas in the cultivating chamber, a freely opening/closing door, a door-locking device, and a controller for controlling the locking device to prevent the door from being opened from start of the sterilization process to end of the decomposition process.
1. A culture apparatus for cultivating cultures in a cultivating chamber, comprising
a sterilizing gas generator that supplies sterilizing gas into the cultivating chamber;
an ultraviolet generator that irradiates gas in the cultivating chamber with an ultraviolet ray; and
a controller that performs a sterilization process for filling the cultivating chamber with the sterilizing gas for a predetermined period of time and a decomposition process for decomposing the sterilizing gas by irradiating the gas in the cultivating chamber with the ultraviolet ray by means of the ultraviolet generator;
wherein the sterilizing gas generator atomizes a sterilizer solution by means of an ultrasonic vibrator; and
wherein the sterilizing gas generator is provided inside the cultivating chamber.
2. The culture apparatus according to claim 1 , wherein the sterilizing gas generator evaporates a sterilizer solution by dipping an absorbing member into the sterilizer solution.
3. The culture apparatus according to claim 2 , wherein the sterilizing gas concentration in the cultivating chamber is from 0.1 ppm to 100 ppm.
4. The culture apparatus according to claim 1 , further comprising
a door for blocking an opening of the cultivating chamber in a free-opening/closing manner and a locking device for prohibiting the door from being opened, wherein the controller controls the locking device to prevent the door from being opened from start of the sterilization process to end of the decomposition process.
5. The culture apparatus according to claim 2 , further comprising an ultraviolet generator that irradiates gas in the cultivating chamber with an ultraviolet ray.
6. The culture apparatus according to claim 1 , wherein the sterilizing gas concentration in the cultivating chamber is from 0.1 ppm to 100 ppm.
7. The culture apparatus according to claim 6 , further comprising an ultraviolet generator that irradiates gas in the cultivating chamber with an ultraviolet ray.
8. The culture apparatus according to claim 7 , further comprising
a controller that performs a sterilization process for filling the cultivating chamber with the sterilizing gas for a predetermined period of time and a decomposition process for decomposing the sterilizing gas by irradiating the gas in the cultivating chamber with the ultraviolet ray by means of the ultraviolet generator.
9. The culture apparatus according to claim 8 , further comprising
a door for blocking an opening of the cultivating chamber in a free-opening/closing manner and a locking device for prohibiting the door from being opened, wherein the controller controls the locking device to prevent the door from being opened from start of the sterilization process to end of the decomposition process.
10. The culture apparatus according to claim 1 , wherein the sterilizing gas concentration in the cultivating chamber is from 0.1 ppm to 100 ppm.
11. The culture apparatus according to claim 10 , further comprising an ultraviolet generator that irradiates gas in the cultivating chamber with an ultraviolet ray.
12. The culture apparatus according to claim 11 , further comprising
a controller that performs a sterilization process for filling the cultivating chamber with the sterilizing gas for a predetermined period of time and a decomposition process for decomposing the sterilizing gas by irradiating the gas in the cultivating chamber with the ultraviolet ray by means of the ultraviolet generator.
13. The culture apparatus according to claim 12 , further comprising
a door for blocking an opening of the cultivating chamber in a free-opening/closing manner and a locking device for prohibiting the door from being opened, wherein the controller controls the locking device to prevent the door from being opened from start of the sterilization process to end of the decomposition process.
14. The culture apparatus according to claim 1 , further comprising an ultraviolet generator that irradiates gas in the cultivating chamber with an ultraviolet ray.
15. The culture apparatus according to claim 14 , further comprising
a controller that performs a sterilization process for filling the cultivating chamber with the sterilizing gas for a predetermined period of time and a decomposition process for decomposing the sterilizing gas by irradiating the gas in the cultivating chamber with the ultraviolet ray by means of the ultraviolet generator.
16. The culture apparatus according to claim 15 , further comprising
a door for blocking an opening of the cultivating chamber in a free-opening/closing manner and a locking device for prohibiting the door from being opened, wherein the controller controls the locking device to prevent the door from being opened from start of the sterilization process to end of the decomposition process.
17. The culture apparatus according to claim 1 , further comprising an ultraviolet generator that irradiates gas in the cultivating chamber with an ultraviolet ray.
18. The culture apparatus according to claim 1 , wherein the sterilizing gas generator includes the ultrasonic vibrator and a vessel provided in a bottom of an inner box.
