Description

Technical Field

[0001] This utility model relates to the field of dry agar culture technology, specifically to a nutrient agar culture medium filling device. Background Technology

[0002] Nutrient agar culture media typically contain agar and other gelling agents, which are difficult to dissolve at room temperature during mixing and tend to clump together. Traditional methods of heating and dissolving before dispensing require costly equipment and consume a lot of energy, which does not meet the requirements of low-carbon and environmental protection. Ordinary stirring devices that use stirring instead of heating have problems such as low stirring efficiency, easy leakage after long-term use, and cannot achieve integrated preparation, stirring and filling.

[0003] Traditional nutrient agar media is dispensed primarily by manual measurement and pouring. This method is not only inefficient and time-consuming, but also makes it difficult to precisely control the amount poured and the temperature during pouring, directly affecting the reliability of experimental results. Furthermore, during manual operation, the risk of contact for the experimenter and the maintenance of a sterile environment are difficult to control, easily leading to contamination of the media.

[0004] During the agar culture process, the culture tank needs to undergo an auxiliary venting process. When venting, workers need to wear heat-resistant gloves and manually rotate the blockage installed on the vent hole. This method can easily cause burns, seriously endangering the workers' health.

[0016] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0017] The present invention will be further described below with reference to the embodiments.

[0018] Example 1: Reference Figure 1-4This first embodiment of the present invention discloses a nutrient agar culture medium filling device, comprising: a circular ring support rod 1 and a culture tank 2. The culture tank 2 is installed at the inner ring of the circular ring support rod 1. A ventilation structure 3 is installed through the upper surface of the culture tank 2. The ventilation structure 3 includes: an arc-shaped mounting plate 4. A rectangular exhaust hole is opened through the upper surface of the culture tank 2. A pair of symmetrical arc-shaped mounting pieces 5 are provided on the arc surface of the arc-shaped mounting plate 4. The same rectangular movable base plate 6 is fixedly connected to the opposite vertical surfaces of the pair of arc-shaped mounting plates 4. A docking hole is opened through the upper surface of the rectangular movable base plate 6. A rectangular baffle 7 is slidably connected to the upper surface of the rectangular movable base plate 6.

[0019] A T-shaped moving block is installed on the lower surface of a pair of rectangular baffles 7. A rectangular moving groove 8 is provided at the intersection of the T-shaped moving block and the rectangular moving base plate 6. A guide rod 9 is provided on the upper surface of each pair of rectangular baffles 7. The same circular guide sleeve is fixedly installed on the upper surface of a pair of arc-shaped mounting plates 4. A circular rotating plate 10 is slidably connected to the inner ring of the circular guide sleeve. A pair of arc-shaped guide grooves 11 are provided on the upper surface of the circular rotating plate 10.

[0020] An arc-shaped hole 12 is provided on the upper surface of the annular rotating plate 10. An arc-shaped fixing plate 13 is provided on the upper surface of the annular rotating plate 10. An arc-shaped block 14 is fixedly connected to the outer ring of the arc-shaped fixing plate 13. Guide blocks are arranged in an array on the outer ring of the arc-shaped block 14. An L-shaped mounting block 15 is fixedly installed on the upper surface of the culture tank 2. A drive motor 16 is provided on the vertical surface of the L-shaped mounting block 15. A cylindrical rod 17 is rotatably connected to the inner ring of the L-shaped mounting block 15. A gear column 18 is fitted on the rod body of the cylindrical rod 17. The gear teeth of the gear column 18 mesh with the guide block. A control device 19 is provided on the vertical surface of the L-shaped mounting block 15.

[0021] When the equipment is in use, the drive motor 16 is started. An L-shaped mounting block 15 is fixedly installed on the upper surface of the culture tank 2. The drive motor 16 is located on the vertical surface of the L-shaped mounting block 15. A cylindrical rod 17 is rotatably connected to the inner ring of the L-shaped mounting block 15. A gear column 18 is fitted onto the rod of the cylindrical rod 17. The gear teeth of the gear column 18 mesh with a guide block. A control device 19 is located on the vertical surface of the L-shaped mounting block 15. (The core of the motor control device is to realize the motor's start, stop, speed adjustment, forward and reverse rotation, and protection.) The motor's operating status can be precisely controlled through electrical or electronic means to adapt to the power requirements of different scenarios. The drive motor 16 can be started by the control device 19. When the drive motor 16 rotates, the cylindrical rod 17 will also rotate, thereby driving the circular rotating plate 10 to rotate through the gear column 18. Because a pair of arc-shaped guide grooves 11 are provided on the upper surface of the circular rotating plate 10, and the guide rod 9 is located in the inner ring of the arc-shaped guide grooves 11, the circular rotating plate 10 causes a pair of rectangular baffles 7 to open, thereby realizing the exhaust process.

[0022] Exhausting air during autoclaving: to prevent pressure imbalance and incomplete sterilization. During this stage, the pressure inside the tank and the sterilizer needs to be balanced, and the cold air inside the tank needs to be expelled at the same time (cold air will cause insufficient local temperature and incomplete sterilization). The key is to "expel the cold air first, and then maintain the pressure".

[0023] Before sterilization: Loosen the lid / open the valve to release cold air. Before placing the container containing liquid agar into the sterilizer, screw the lid to a "semi-sealed" position (or open the vent valve) to ensure that the inside of the container is open to the outside. In the initial stage of sterilization (from room temperature to about 100℃, about 5-10 minutes), cold air inside the can will be expelled as the temperature rises. If the can is completely sealed at this time, the cold air will be trapped at the bottom of the can, resulting in local sterilization temperatures below 121℃ and creating sterilization dead zones.

[0024] During sterilization: Keep it slightly open. After the pressure sterilizer reaches the set temperature (121℃) and starts timing, if there is too much steam in the can and the sealing cap tends to "bulge", you can slightly tighten the cap (or close the exhaust valve) to leave only a small gap for excess steam to escape, so as to avoid the can being deformed due to excessive pressure. Do not completely close the exhaust channel to prevent the pressure inside the can from exceeding the sterilizer pressure.

[0025] After sterilization: reduce the pressure before closing the valve to avoid negative pressure suction of bacteria. After sterilization, wait until the pressure in the sterilizer drops to "0MPa" and the temperature drops below 100℃ before closing the exhaust valve of the tank or tightening the sealing cap. If the container is sealed without depressurization, a negative pressure will form inside after the container cools down, which may draw in bacteria-laden air from the outside through the gaps in the container opening, leading to contamination after sterilization.

[0026] Example 2: Reference Figure 1 This is the second embodiment of the present invention. The difference between this embodiment and the first embodiment is that: a U-shaped mounting sleeve is provided on the bottom surface of the culture tank 2, a cylindrical loading rod 20 is rotatably connected to the upper surface of the U-shaped mounting sleeve, a circular mounting sleeve is fitted on the rod of the cylindrical loading rod 20, a stirring blade 21 is installed on the arc surface of the circular mounting sleeve, and a pair of symmetrical rectangular mounting strips 22 are provided on the outer ring of one of the circular mounting sleeves, and defoaming rods are arranged in an array on the lower surface of the rectangular mounting strips 22.

[0027] When using this equipment, first start the drive motor connected to the cylindrical loading rod 20. The cylindrical loading rod 20 has a circular mounting sleeve fitted onto its body, and the stirring blades 21 are mounted on the curved surface of the circular mounting sleeve. One of the circular mounting sleeves also has a pair of symmetrical rectangular mounting strips 22 on its outer ring. The lower surface of the rectangular mounting strips 22 is arrayed with defoaming rods (defoaming rods are a common term referring to smooth or finely textured round rods that break the surface tension of foam through stirring and scraping, causing bubbles to burst. Suitable for: laboratory culture medium stirring, industrial reactors, sewage treatment tanks, food processing such as soy milk and juice, etc., and also perfectly suited for foam treatment during nutrient agar stirring as you mentioned earlier). Once the cylindrical loading rod 20 starts rotating, the stirring blades 21 will ultimately perform the stirring function.

[0028] The remaining structure is the same as that in Example 1.

[0029] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of this utility model.
