Description

Technical Field

[0001] The utility model relates to a supporting production device for agricultural products, in particular to a liquid strain fermentation tank. Background Art

[0002] With the development of strain production technology, liquid strains have become one of the important ways to inoculate edible fungi. They have fast inoculation speed and seed production speed. Fermentation tanks are indispensable devices in the cultivation of liquid strains. During the cultivation of liquid strains, in order to prevent the fermentation tanks from having foreign bacteria during the cultivation process, the fermentation tanks need to be fully cleaned and sterilized before cultivation. Conventional fermentation tanks are sterilized by high-temperature steam, but it takes a long time and consumes a lot of energy. For some strains that do not require a high sterilization rate, such as velvet antler mushrooms, seafood mushrooms and other strains, the time requirements are higher. At the same time, liquid strains require sufficient oxygen during the cultivation process. However, conventional fermentation tanks can only be cultivated by extending the stirring time of the stirring rod so that the strains on the surface of the culture solution are in contact with the oxygen in the tank body. The number of strains in contact with oxygen is small, which reduces the cultivation efficiency of liquid strains.

[0003] Therefore, there is an urgent need for a new type of liquid strain fermentation tank, which can quickly clean and sterilize the inside of the tank body, and at the same time, can provide sufficient oxygen for the growth of the strain during the strain cultivation process. Utility Model Content

[0004] In order to solve the above technical problems, the utility model provides a liquid strain fermentation tank, which can quickly clean and sterilize the inside of the tank body, and at the same time, can provide sufficient oxygen for the growth of the strain during the strain cultivation process.

[0005] The utility model adopts the following technical solutions:

[0006] A liquid strain fermentation tank comprises a tank body, wherein a stirring mechanism for stirring liquid is vertically arranged inside the tank body, and a flushing mechanism is arranged on the top of the tank body; the stirring mechanism comprises a motor, a rotating body arranged inside the tank body and connected to the motor power, and a plurality of stirring rods arranged around the side of the rotating body, wherein the rotating body and the stirring rods are both hollow structures, a plurality of air jet holes are penetrated through the side of the stirring rod, a swivel joint is fixedly arranged at the bottom of the rotating body, and a ventilation pipe for ventilation with the outside is fixedly connected to the swivel joint; the flushing mechanism comprises an annular tube with a hollow structure, a plurality of nozzles penetrated through the outer wall of the annular tube, and an infusion tube penetrated and connected with the annular tube for inputting cleaning and sterilizing liquid, and the nozzles are evenly arranged on the top surface, bottom surface and outer side surface of the annular tube.

[0007] Furthermore, in order to ensure the firmness of the swivel joint, a plurality of fixing columns for fixing the swivel joint are arranged around the inner side of the tank body. In order to ensure the pressure of the cleaning and sterilizing liquid in the annular tube, thereby ensuring the pressure and coverage of the spray head, a water pump is connected to the infusion tube.

[0008] Furthermore, in order to ensure that the jet holes on the stirring rod can continuously and effectively spray gas, an air pump is connected to the ventilation pipe. In order to further increase the contact density between the liquid bacteria and oxygen and improve the growth rate, the jet holes include a first jet hole with a vertical jet direction and a second jet hole located on the outside of the end of the stirring rod with a horizontal jet direction.

[0009] Preferably, in order to ensure smooth rotation of the rotating body, thereby smoothly driving the stirring rod to effectively stir the liquid containing the bacterial strain, the motor adopts a servo reduction motor.

[0010] From the above description of the structure of the utility model, it can be seen that compared with the prior art, the utility model has the following advantages: the utility model is provided with a flushing mechanism, and the external cleaning and sterilizing liquid is sprayed out from the nozzle through the infusion tube and the annular tube under the action of the water pump, which can not only sterilize the inside of the tank body through its own sterilization effect, but also the liquid sprayed out with high pressure can also flush away the pollutants inside the tank body under its own physical water pressure impact, thereby improving the cleaning and sterilization effect; at the same time, the utility model is provided with a jet hole for discharging oxygen on the rotating stirring rod, so that the stirring rod can realize the function of discharging oxygen to the bacterial culture solution while stirring, thereby increasing the number of bacteria in contact with oxygen, increasing the growth rate of the bacteria in the culture solution, and improving the culture efficiency of liquid bacteria.
