Description

Technical Field

[0001] The utility model belongs to the technical field of fermentation tanks, and particularly relates to a liquid strain fermentation tank with a filtering function. Background Technique

[0002] Liquid strains are a kind of seed production process in which mother strains are cut into filaments and put into a fermentation tank together with a culture solution, and liquid edible mushroom strains are formed through reasonable and sufficient fermentation. Liquid strains are widely used because of their advantages such as good fluidity, easy dispersion, fast germination, and many germination points. The existing edible mushroom liquid strain fermentation tanks include a tank body, in which an air pipe is provided. The air pipe is connected to an air supply device to jet oxygen into the culture solution in the tank body. Generally, a temperature measuring module such as a temperature sensor or a thermometer is also provided in the tank body to detect the temperature of the culture solution. A heating module is also provided on the tank body. When the temperature measuring module detects that the temperature of the culture solution is too low, the culture solution is heated through the heating module to avoid affecting the culture effect of the strains due to too low temperature of the culture solution. However, due to different growth rates of the strains during the culture process, the sizes of the strains are different. For example, if smaller strains are sown in a solid medium, the sown strains are difficult to survive or grow poorly. Based on the fact that the existing fermentation tanks cannot screen out small strains and use large strains for sowing after culturing. Providing a liquid strain fermentation tank with a filtering function can facilitate screening out small strains and using large strains for sowing, and also facilitate continuous culturing of small strains, ensuring the sowing quality and avoiding waste of strains. Summary of the Utility Model

[0018] See Figures 1 to 2 , the present utility model provides a liquid spawn fermenter with a filtering function, including a support rod 3, a heating device and an oxygen supply device. A swing rod 16 and a base 1 are respectively provided at the upper and lower ends of the support rod 3. The support rod 3 is vertically and fixedly arranged at the middle of the upper surface of the base 1. The base 1 is used to fix the support rod 3. The middle part of the swing rod 16 is hinged to the upper end of the support rod 3. An electric push rod 15 is hinged to one side of the upper part of the support rod 3. The telescopic end of the electric push rod 15 is hinged to the swing rod 16. The electric push rod 15 can drive the swing rod 16 to swing at the upper end of the support rod 3. Fermenters 8 are hinged at both ends of the swing rod 16. The swing rod 16 can drive the two fermenters 8 to alternately rise and fall. When starting to cultivate liquid spawn, the left side is an empty tank, and the right side is used to cultivate liquid spawn. Coarse filters 17 and fine filters 7 in the shape of a lower-end open cylinder are respectively fixed at the bottoms of the two fermenters 8 on the right side and the left side. A flexible water pipe 4 is connected between the top of any one fermenter 8 and the bottom of the other fermenter 8. A valve 6 is provided on the flexible water pipe 4. During the process of cultivating liquid spawn, all valves 6 are in a closed state. The valve 6 can be a manual valve or an electromagnetic valve. If an electromagnetic valve is used, the switch can be controlled by a controller 2. The water inlet ends of the two flexible water pipes 4 are respectively arranged inside the coarse filter 17 and the fine filter 7. The bottom of the fermenter 8 is of a contraction structure, which is beneficial to fully discharge the culture solution and spawn into the flexible water pipe 4. The heating device is used to heat the inside of the fermenter 8, and the oxygen supply device is used to jet air into the fermenter 8 to increase oxygen;

[0019] During the screening process of the present invention, the electric push rod 15 shortens to drive the swing rod 16 to swing on the support rod 3. The swing rod 16 drives the fermentation tank 8 for cultivating bacteria on the right side to rise higher than the empty fermentation tank 8 on the left side. The valve 6 on the soft water pipe 4 at the bottom of the right fermentation tank 8 is opened. Under the action of gravity, the small bacteria in the right fermentation tank 8 are screened into the left fermentation tank 8 under the flushing of the culture solution, while the small bacteria are blocked in the right fermentation tank 8 by the coarse filter screen 17. When all the culture solution is drained, the above-mentioned valve 6 is closed. Then, the electric push rod 15 extends to drive the swing rod 16 to swing in the reverse direction, so that the large bacteria fermentation tank 8 on the right side is located below the small bacteria fermentation tank 8 on the left side. The valve 6 on the soft water pipe 4 at the bottom of the left small bacteria fermentation tank 8 is opened, so that the culture solution in the left small bacteria fermentation tank 8 is screened out and flows back into the large bacteria fermentation tank 8. The small bacteria are blocked in the left fermentation tank 8 by the fine filter screen 7. When all the culture solution in the left fermentation tank 8 flows back into the fermentation tank 8 on the right side, the above-mentioned valve 6 is closed. The screening is carried out multiple times according to the above operations, so that the bacteria in the right fermentation tank 8 are washed by the culture solution multiple times and flow into the fermentation tank 8 on the left side, which can improve the screening effect. Finally, new culture solution is put into the small bacteria fermentation tank 8 for continuous cultivation, and the liquid bacteria in the large bacteria fermentation tank 8 can be directly used for sowing, which is convenient for screening large and small bacteria and continuously cultivating small bacteria.
