Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] See also Figure 1-6 , the utility model provides a technical solution:

[0023] A deep fermentation container for bacterial strains includes an electric control box 6, which is installed on the side of a heat-insulating protective shell 1. A fermentation bin 2 for fermentation is arranged inside the heat-insulating protective shell 1. A stirring structure 3 capable of stirring the inside of the fermentation bin 2 is installed between the heat-insulating protective shell 1 and the fermentation bin 2. A temperature control system 5 for controlling the temperature inside the fermentation bin 2 is also arranged inside the heat-insulating protective shell 1. The fermentation bin 2 is driven to shake by the stirring structure 3, thereby replacing the traditional built-in stirring structure, so that there is basically no dead corner for cleaning inside the fermentation bin 2, and the fermentation bin 2 is isolated from the external environment by the heat-insulating protective shell 1, so that the external environment basically has no effect on the temperature of the fermentation bin 2.

[0024] Inspection openings 7 are provided on both sides of the thermal insulation and protective shell 1, and a cover plate 8 is installed on the outside of the thermal insulation and protective shell 1 at the position corresponding to the inspection opening 7, which not only facilitates the inspection of the interior of the thermal insulation and protective shell 1, but also enables the thermal insulation and protective shell 1 to be sealed through the cover plate 8, so that the external environment basically does not contact the fermentation bin 2, thereby ensuring the temperature stability inside the fermentation bin 2.

[0025] A connecting port 9 for material input and output is provided at the end of the fermentation bin 2, and a valve 10 is installed on the connecting port 9. The material input and output operations are carried out by opening the valve 10, while reducing the number of openings and the risk of leakage. A mounting hole 13 is provided on the fermentation bin 2 on the side of the connecting port 9, and a sealing plug 14 is connected to the internal thread of the mounting hole 13. A temperature sensor 15 is installed at the bottom end of the sealing plug 14, thereby facilitating the measurement of the temperature inside the fermentation bin 2. A pressure relief pipe 11 is installed on the fermentation bin 2 on the side of the mounting hole 13, and a pressure relief valve 12 is installed on the pressure relief pipe 11, thereby facilitating pressure relief operations.

[0026] Support shafts 19 are symmetrically installed on both sides of the fermentation bin 2, and a bearing seat 20 is installed on the inner wall of the heat-insulating protective shell 1 at the position corresponding to the support shaft 19. A temperature control channel 4 is opened in the wall of the fermentation bin 2, so that the fermentation bin 2 can rotate with the support shaft 19 as the axis.

[0027] The temperature control channel 4 includes annular holes 17 distributed in the wall of the fermentation bin 2, and a connecting hole 21 is opened inside the support shaft 19. The connecting hole 21 is connected to the annular hole 17 through the connecting hole 18, thereby making the interior of the temperature control channel 4 connected, thereby facilitating the temperature control of the interior of the fermentation bin 2.

[0028] Two sets of stirring structures 3 are provided, and both sets of stirring structures 3 include a U-shaped seat 1 22 and a U-shaped seat 24. The U-shaped seat 1 22 is installed on the inner wall of the heat-insulating protective shell 1, and the U-shaped seat 24 is installed on the fermentation bin 2. A sleeve ring 23 is installed for rotation inside the U-shaped seat 22, and a sleeve ring 25 is installed for rotation inside the U-shaped seat 24. An electric push rod 26 is installed between the sleeve ring 1 23 and the sleeve ring 25.

[0029] The temperature control system 5 includes air chambers 27 and water tanks 31 which are sequentially opened from the inside to the outside in the shell walls on both sides of the heat-insulating protective shell 1, and the air chambers 27 on both sides of the heat-insulating protective shell 1 are connected through air supply channels 29, and a blower 30 is installed inside the air supply channels 29. The air chamber 27 is connected with the connecting hole 21, and a guide plate 28 is distributed inside the air chamber 27. The blower 30 works to drive the airflow in the air chamber 27 on one side of the heat-insulating protective shell 1 along the air supply channel 29 to enter the air chamber 27 on the other side of the heat-insulating protective shell 1, and then enter the temperature control channel 4 through the connecting hole 21 on one side, and finally flow back to the initial air chamber 27 from the connecting hole 21 on the other side, so as to circulate, thereby ensuring that the airflow entering the temperature control channel 4 can fully contact the wall of the water tank 31, so that the airflow temperature is basically the same as the internal temperature of the water tank 31, so that the temperature inside the fermentation bin 2 can be heated to the required temperature.

[0030] The water tanks 31 on both sides of the thermal insulation protective shell 1 are connected by two interactive channels 32, and a water pump 33 is installed inside one of the interactive channels 32, so that the water inside the water tank 31 is in a flowing state, thereby ensuring the consistency of water temperature. An installation port 34 and a fixing hole 37 are opened at the top of the thermal insulation protective shell 1 corresponding to the position of the water tank 31, and a sealing plate 35 is fixed to the inside of the installation port 34 by threads. The bottom end of the sealing plate 35 is installed with an electric heating pipe 36 that penetrates into the water tank 31, thereby facilitating the removal, maintenance and replacement of the electric heating pipe 36. The internal thread of the fixing hole 37 is connected with a fixing column 38, and a connecting rod 39 is installed at the bottom end of the fixing column 38. A temperature sensor 40 is installed at the bottom end of the connecting rod 39, thereby facilitating the detection of the temperature inside the water tank 31.
