[0002] Soy sauce is a common condiment in our life and is needed in many dishes. When producing soy sauce, the soy sauce needs to be fermented to obtain the taste we need.

[0003] The utility model patent with the application number CN202120763119.X discloses a soy sauce fermentation tank convenient for adjusting temperature, which includes a tank body. A sandwich cavity is provided inside the side wall of the tank body, and a heater is fixed in the sandwich cavity. It also includes a cooling device. The cooling device includes a heat dissipation pipe, which is spirally arranged in the sandwich cavity. An adjusting mechanism for adjusting the cooling effect of the heat dissipation pipe is provided on the heat dissipation pipe, so as to conveniently adjust the temperature inside the tank body and improve the quality of soy sauce fermentation.

[0004] However, the above fermentation tank cools the inside of the fermentation tank externally, and the cooling efficiency of the materials inside the fermentation tank is low, resulting in the inactivation of fermentation bacteria due to excessive temperature for a long time, which needs to be improved. Summary of the Utility Model

[0005] The technical problem to be solved by the utility model is to provide an automatic monitoring device for the soy sauce fermentation process, which can cool the materials from the inside of the fermentation tank to solve the problems in the prior art.

[0006] To solve the above technical problem, the technical solution of the utility model is: an automatic monitoring device for the soy sauce fermentation process, including a fermentation tank, and a heating mechanism is arranged on the outer side of the fermentation tank; a plurality of temperature sensors are fixedly installed in the fermentation tank at uniformly spaced intervals vertically; a water inlet pipe driven by a motor to rotate is arranged on the top wall of the fermentation tank. The water inlet pipe vertically penetrates the top wall of the fermentation tank. A support frame is fixedly installed on the water inlet pipe located inside the fermentation tank. A vertically extending liquid inlet pipe and a liquid outlet pipe are fixedly installed on the support frame. The lower end of the water inlet pipe is communicated with the liquid inlet pipe. A plurality of horizontally extending cooling pipes are fixedly connected between the liquid inlet pipe and the liquid outlet pipe. The cooling pipes correspond to the temperature sensors one by one. The plurality of cooling pipes are arranged at uniformly spaced intervals vertically. A solenoid valve is arranged at the liquid inlet end of the cooling pipe. The lower end of the support frame is fixedly installed with a transfer pipe coaxially arranged with the water inlet pipe. The upper end of the transfer pipe is communicated with the liquid outlet pipe. A water outlet pipe coaxially arranged with the water inlet pipe is fixedly installed on the bottom wall of the fermentation tank. The water outlet pipe vertically penetrates the bottom wall of the fermentation tank. The lower end of the transfer pipe is rotatably connected to the upper end of the water outlet pipe.

[0007] As a further improvement, the water inlet pipe and the water outlet pipe are coaxially arranged with the fermentation tank, and the liquid inlet pipe and the liquid outlet pipe are symmetrically arranged with respect to the axis of the fermentation tank.

[0008] As a preferred technical solution, the heating mechanism includes a jacket fixedly installed on the outer side of the lower end of the fermentation tank. The lower end of the water outlet pipe passes through the outer side of the jacket. A water bath cavity is provided between the jacket and the outer wall of the fermentation tank. A plurality of heating pipes are fixedly installed in the water bath cavity at uniformly spaced intervals in the vertical direction, and the heating pipes correspond to the temperature sensors one by one.

[0011] After adopting the above technical solutions, the beneficial effects of the present utility model are as follows:

[0012] (1) In this application, when the top temperature sensor or multiple upper temperature sensors detect that the material temperature at the corresponding depth exceeds the preset value, the controller drives the air charging and discharging pump to extract the gas in the air bag, so that the liquid level in the water bath cavity drops, and the material with a temperature exceeding the preset value in the upper layer is no longer heated by the water bath, thereby improving the efficiency of material cooling;

[0013] (2) During the fermentation process of this application, the motor drives the water inlet pipe to rotate, and then the water inlet pipe drives the support frame, the liquid inlet pipe, the liquid outlet pipe and multiple cooling pipes to rotate. The support frame, the liquid inlet pipe, the liquid outlet pipe and multiple cooling pipes can stir the materials in the fermentation tank, so that the materials in the fermentation tank are evenly heated;

[0014] (3) In this application, when the top temperature sensor or multiple upper temperature sensors detect that the material temperature at the corresponding depth exceeds the preset value, the controller opens the solenoid valves on the corresponding one or more cooling pipes, and then the cooling water flows through the cooling pipes to take away the heat of the material at the corresponding depth, thereby cooling the material inside the fermentation tank, and the cooling efficiency of the material is higher.

Detailed implementation manners

[0020] As Figures 1 to 3 shown, an automatic monitoring device for the soy sauce fermentation process includes a cylindrical fermentation tank 1. A feeding port 2 is provided at the top of the fermentation tank 1, and a discharge pipe 3 is provided at the bottom of the fermentation tank 1.

[0021] As Figure 2 shown, a heating mechanism is provided outside the fermentation tank 1. The heating mechanism includes a jacket 4 fixedly installed on the outer side of the lower end of the fermentation tank 1. The jacket 4 is fixed or welded to the outer side of the fermentation tank 1 by bolts. A water bath cavity 5 is provided between the jacket 4 and the outer wall of the fermentation tank 1. A plurality of heating pipes 6 are fixedly installed in the water bath cavity 5 at uniformly spaced intervals in the vertical direction. The heating pipes 6 are arranged in a ring shape. The heating pipes 6 are fixedly installed on the inner wall of the jacket 4 through support rods. A plurality of temperature sensors 7 are fixedly installed on the inner wall of the fermentation tank 1 at uniformly spaced intervals in the vertical direction. The heating pipes 6 and the temperature sensors 7 are in one-to-one correspondence. Water is provided in the water bath cavity 5, and the water in the water bath cavity 5 is heated through the heating pipes 6, and then the fermentation tank 1 is heated by the water bath method. The heating pipes 6 and the temperature sensors 7 are both connected to the controller.

[0022] During the fermentation process, the temperatures of the materials at different depths in the fermentation tank 1 are detected by multiple temperature sensors 7. When the temperature of the material at a corresponding depth detected by a certain temperature sensor 7 exceeds the preset value, the corresponding heating tube 6 is closed through the controller, thereby stopping heating the water at the corresponding depth in the water bath chamber 5.

[0023] As Figure 1 and Figure 3 shown, the heating mechanism further includes a heat preservation box 8. A return water pipe 9 is connected between the bottom of the jacket 4 and one side of the bottom of the heat preservation box 8. A water pump 10 is provided on the return water pipe 9. An overflow pipe 11 is connected between the top of the heat preservation box 8 and one side of the top of the jacket 4. When the water pump 10 works, the hot water in the water bath chamber 5 is pumped out through the return water pipe 9 into the heat preservation box 8; when the heat preservation box 8 is full of water, the water pump 10 continues to work so that the water in the heat preservation box 8 overflows back into the water bath chamber 5 through the overflow pipe 11.

[0024] An air bag 12 is provided in the heat preservation box 8. An air charging and discharging pipe 13 is fixedly installed on one side wall of the heat preservation box 8. One end of the air charging and discharging pipe 13 is connected to the air bag 12 and the other end extends outside the heat preservation box 8 and is connected to an air charging and discharging pump 14. When the air bag 12 is fully inflated, when the water in the heat preservation box 8 overflows back into the water bath chamber 5 through the overflow pipe 11, the liquid level in the water bath chamber 5 will be higher than the height of the uppermost temperature sensor 7. The air charging and discharging pump 14 is connected to the controller.

[0025] During the heating process of the materials in the fermentation tank 1, when the materials are heated and flow upward, the temperature of the materials in the upper layer will be higher than that of the materials in the lower layer. When the uppermost temperature sensor 7 or multiple temperature sensors 7 above detect that the temperature of the materials at the corresponding depth exceeds the preset value, the controller drives the air charging and discharging pump 14 to extract the gas in the air bag 12, so that more water can be accommodated in the heat preservation box 8 and the liquid level in the water bath chamber 5 drops until the liquid level in the water bath chamber 5 drops below the corresponding one or more temperature sensors 7, so that the liquid level in the water bath chamber 5 only submerges the temperature sensors 7 whose temperatures do not exceed the preset value, and the materials in the upper layer whose temperatures exceed the preset value are no longer heated by the water bath, thereby improving the efficiency of material cooling.

[0026] In order to evacuate the air in the heat preservation box 8, an exhaust port 15 is provided on one side of the top of the jacket 4.

[0027] As Figure 2As shown in the figure, a vertically extending water inlet pipe 16 is rotatably installed on the top wall of the fermentation tank 1 through a bearing. The water inlet pipe 16 is coaxially arranged with the fermentation tank 1. The water inlet pipe 16 vertically penetrates the top wall of the fermentation tank 1. The upper end of the water inlet pipe 16 is connected with a water inlet connecting pipe 17 through a rotary joint, and the water inlet connecting pipe 17 is connected to a cooling water source. A motor 18 is installed on the top of the fermentation tank 1 through a bracket, and the rotating shaft of the motor 18 is connected to the water inlet pipe 16 through a belt. A support frame 19 is fixedly installed on the water inlet pipe 16 located inside the fermentation tank 1. The support frame 19 is rectangular. The water inlet pipe 16 is welded to the top wall of the support frame 19 and the lower end of the water inlet pipe 16 penetrates the top wall of the support frame 19. A vertically extending liquid inlet pipe 20 and a liquid outlet pipe 21 are fixedly installed between the top wall and the bottom wall of the support frame 19 through bolts. The liquid inlet pipe 20 and the liquid outlet pipe 21 are symmetrically arranged with respect to the axis of the fermentation tank 1. The lower end of the water inlet pipe 16 is connected to one side of the top of the liquid inlet pipe 20 through a first elbow 22. A plurality of horizontally extending cooling pipes 23 are fixedly connected between the liquid inlet pipe 20 and the liquid outlet pipe 21. The cooling pipes 23 correspond to the temperature sensors 7 one by one. The plurality of cooling pipes 23 are vertically and evenly spaced. The end of the cooling pipe 23 close to the liquid inlet pipe 20 is the liquid inlet end. A solenoid valve 24 is provided at the liquid inlet end of the cooling pipe 23. The solenoid valve 24 is connected to the controller. A one-way valve for conducting from the cooling pipe 23 to the liquid outlet pipe 21 is provided inside the liquid outlet end of the cooling pipe 23 to prevent the cooling water in the liquid outlet pipe 21 from flowing back into the cooling pipe 23. A transfer pipe 25 coaxially arranged with the water inlet pipe 16 is welded to the bottom wall of the support frame 19. The transfer pipe 25 vertically penetrates the bottom wall of the support frame 19. The upper end of the transfer pipe 25 is connected to one side of the lower end of the liquid outlet pipe 21 through a second elbow 26. A water outlet pipe 27 coaxially arranged with the water inlet pipe 16 is fixedly installed or welded to the bottom wall of the fermentation tank 1 through bolts. The water outlet pipe 27 vertically penetrates the bottom wall of the fermentation tank 1. The lower end of the water outlet pipe 27 penetrates outside the jacket 4. The lower end of the transfer pipe 25 is rotatably connected to the upper end of the water outlet pipe 27 through a rotary joint. Heat insulation layers are provided inside the water inlet pipe 16, the first elbow 22, the liquid inlet pipe 20, the liquid outlet pipe 21, the second elbow 26, the transfer pipe 25 and the water outlet pipe 27. The cooling pipe 23 is made of a heat-conducting metal material.

[0028] During the fermentation process, the water inlet pipe 16 is driven to rotate by the motor 18. Subsequently, the water inlet pipe 16 drives the support frame 19, the liquid inlet pipe 20, the liquid outlet pipe 21, and multiple cooling pipes 23 to rotate. Through the support frame 19, the liquid inlet pipe 20, the liquid outlet pipe 21, and multiple cooling pipes 23, the materials in the fermentation tank 1 can be stirred, so that the materials in the fermentation tank 1 are evenly heated. When the temperature sensor 7 detects that the temperature of the materials in the fermentation tank 1 is within the preset range, the solenoid valve 24 is in the closed state, and the cooling water cannot flow through the cooling pipes 23 to cool the materials in the fermentation tank 1. When the top temperature sensor 7 or multiple temperature sensors 7 located above detect that the temperature of the materials at the corresponding depth exceeds the preset value, the controller is used to open the solenoid valve 24 on the corresponding one or more cooling pipes 23. Then, the cooling water flows through the water inlet pipe 16, the first elbow 22, the liquid inlet pipe 20, the cooling pipes 23, the liquid outlet pipe 21, the second elbow 26, the adapter pipe 25, and the water outlet pipe 27 in sequence and is discharged. When the cooling water flows through the cooling pipes 23, the heat of the materials at the corresponding depth is carried away, so as to cool the materials inside the fermentation tank 1, and the cooling efficiency of the materials is higher.
