By rapidly adapting to sudden changes in liquid temperature, the culture liquid is always kept at a constant temperature, so that a more stable culture liquid of all fungal algae, including raw chlorella, can be obtained, and at the same time, in the culture tank. The atmosphere is forcibly introduced into the air, the atmosphere is converted into a gas containing a large amount of oxygen, and the air is exhausted to clean the surrounding air. By adopting this method, the pH was adjusted as desired, and heating and filtration were immediately performed by the combined use of a heating filtration system to complete a fungal algae culture apparatus for collecting a fungal algae culture solution.

Further, to explain the fungal algae culture device manufactured and tested by the applicant, a bottomed short cylinder having a diameter of 1400 mm made of reinforced plastics (FRP) with a bottom part made of a steel plate and having a heater 1 attached thereto. Inject 500 liters of water (tap water / natural water) into the container 7, and inject 30 liters of chlorella stock solution and sun crogen (mixture of chlorella breeding material that is a mixture of soy sauce and vinegar in a ratio of 3: 2) of 100 cc. To do.

Next, the forward / reverse reversible motor 12 is fixed to the horizontal holding plate 20, the horizontal holding plate 20 is fixed in the diameter direction of the opening of the container 7, and a polycarbonate umbrella-shaped transparent member is provided above the motor 12. The optical lid 8 is fixed so as to cover the opening 7'of the container 7, and the stirrer 6 (blades in the drawing) directly connected to the motor 12 is submerged in water. Stir the injection solution. At this time, the heater 1
Is 1200 W, and the cooler 10 installed in machine base b is 2150
The one having the performance of Kcal / h is adopted, and the temperature inside the culture tank a is controlled by the liquid temperature sensor 2.

Further, the culture tank a is placed on the machine base b, the cooler 10 and the air supply port 4 of the container 7 are connected by a duct 11 having a diameter of 100 mmφ, and a cord of a motor 12 for driving the agitator 6. 12 ', liquid temperature sensor 2 cord 2', cooler 10 power cord 10 ', cooler 10 blast cord 10 ", cooler 10

Configure to operate the drain valve of.

When the apparatus is operated, the air and the cold air are forcibly introduced into the culture tank a from the duct 11 under the condition of about 6 m ³ / min,
It is discharged to the outside from the exhaust port 5 on the opposite side. Agitator 6 at the same time
The mixture of water, the chlorella stock solution, and the sun crogen is stirred by the rotation of the. At this time, the motor 12 repeats normal rotation / reverse rotation every few minutes, and the continuous operation is performed under the condition that the arrival time from the rotation speed of 120 rpm to the maximum rotation speed of 1200 rpm is about 25 seconds.

Further, the compressor of the cooler 10 is operated by the power cord 10 'of the cooler 10, and by turning on / off the compressor, a cool air of a set temperature, for example, 28 ° C. is generated, and the blower code 10 "of the cooler 10 is used to cool the cooler 1.
Cold air is forcibly introduced into the culture tank a by the blower in 0, and the temperature of this cold air is controlled by the controller 9 by the cold temperature sensor 13.

The mixed solution in the culture tank a is constantly stirred and sunlight is taken in from the translucent lid 8 and atmospheric air is taken in from the duct 11 via the cooler 10 at a time of 100 cc once a day. Input port for sun crogen (mixed solution of soy sauce and vinegar)
Inject from 21. After continuous operation for one week, a raw chlorella beverage stock solution having a concentration of 97% water and 3% chlorella per 1 liter of liquid was obtained. After one month, 30 liters of the live chlorella culture solution in the culture tank a was left, and water 500 was added again.
The same result was obtained when liters were added and the same procedure as above was repeated.

In this culture tank a, since the mixed solution in the container 7 is constantly stirred by the stirrer 6 which is rotated in the normal and reverse directions, the mixed solution always comes in contact with the introduced air while being mixed up and down to mix. Chlorella in the liquid effectively absorbs carbon dioxide in the atmosphere, and at the same time, chlorella releases oxygen. Therefore, this culture tank a sucks carbon dioxide gas from the atmosphere introduced from the air supply port 4, converts it into a gas containing a large amount of oxygen, and discharges it from the exhaust port 5, so that it has an action of cleaning the surrounding atmosphere. Demonstrate.

It is possible to adjust so that a culture solution having a desired pH value can always be obtained. In this case, the ion concentration can be adjusted as desired by providing the ion measuring sensor 16 and the ion measuring meter 17 in the culture tank a and in the control device 9 and connecting them.

Further, a heating / filtering device c is provided side by side, and the raw culture liquid in the culture tank a is introduced from the liquid draining section 3 of the culture tank a into the liquid guiding tube 19
Introduced into the heating / filtering device c from the liquid introducing section 18 via the liquid, and immediately heated (heated at 100 ° C. or higher for sterilization, but instantaneous heating under high pressure is preferable), filtered and stabilized fungal algae culture liquid To collect.

In the figure, reference numeral 23 is a monitoring window provided on the operation door 22 of the control device 9, 24 is a liquid collecting section, and 25 is a filter.

[0022]

Since the present invention is configured as described above, by setting a desired liquid temperature in advance, when the temperature exceeds the set temperature due to the surrounding weather conditions, the cooler works to instantly set the temperature. When it is cooled to the temperature, and when it falls below the set temperature, the heater works to instantly warm it to the set temperature. Therefore, the liquidity during operation always has a small error with respect to the set temperature, and the culture solution is always stirred uniformly.
Furthermore, the translucent lid takes in the maximum amount of sunlight, which makes the culture activity even more active. Therefore, a uniform and stable fungal algae culture solution can always be obtained, and at the same time, a gas containing an extremely large amount of oxygen can be released, so that a contaminated air cleaning action can be exerted and various equipment can be related by a control device. The pH can be controlled as desired, and the pH can be adjusted as desired.

Moreover, the excellent fungal algae culture device can be immediately installed in parallel with the heating and filtration treatment device to collect a stable fungal algae culture solution.
