Description

Technical Field

At present, most soy sauces are made from raw materials such as soybeans, wheat bran and salt through fermentation. The nutritional ingredients are relatively simple and the taste is single. In order to meet market demand, milk soy sauce was developed. Milk soy sauce is a condiment brewed with milk and soybeans as the main raw materials. It has the characteristics of high amino acid content, zero additives and unique flavor. It is suitable for a variety of cooking methods and is suitable for people of all ages. In the production process of milk soy sauce, the raw materials need to be fermented in a fermentation tank, and the raw materials need to be controlled to remain at the set temperature and humidity for a long time.

The soy sauce is heated by the heating coil arranged inside the tank body, so that the temperature of the soy sauce is within a suitable range for fermentation; and an air pipe is arranged at the bottom of the tank body of the fermentation tank, and clean air is output through the air pipe. When the air is discharged upward from the bottom of the tank body through the soy sauce, the soy sauce in the tank body is stirred to promote the flow of the soy sauce.

[0004] When the above scheme is implemented, it uses the gas input from the bottom to stir the raw materials, saving the installation cost of the stirring device. Since the flow direction of the gas is chaotic, the raw materials in the tank cannot be stirred in an orderly manner, resulting in uneven mixing.

[0018] Two implementation modes of the present application are described in detail below with reference to the accompanying drawings.

[0019] The first implementation method: Figure 1-Figure 5 A fermentation device for producing milk soy sauce is shown, comprising a fermentation tank body 1, a mixing auxiliary heat mechanism and a fermentation intelligent controller 4. The bottom of the fermentation tank body 1 is connected with a down-through pipe 2, and the top of the fermentation tank body 1 is connected with an up-through pipe 3 and an exhaust pipe 8. A temperature measuring rod 10 is vertically inserted in the middle of the fermentation tank body 1. The temperature measuring rod 10 is equipped with a plurality of temperature sensors along its axial direction. By installing a plurality of temperature sensors on the temperature measuring rod 10, when the temperature measuring rod 10 is vertically inserted into the fermentation tank body 1, the temperature of raw materials at different depths of the fermentation tank body 1 can be detected, the temperature state of the raw materials in the fermentation tank body 1 can be judged, and the quality of the produced soy sauce can be improved.

[0020] It is worth mentioning that see Figure 2-Figure 4 The mixed auxiliary heating mechanism includes a heating coil 11 arranged at the bottom of the inner cavity of the fermentation tank body 1, an air inlet pipe 5 connected to the heating coil 11, and a circulating mixing mechanism 12 arranged above the heating coil 11. A plurality of exhaust holes are provided on the top of the heating coil 11. The input end of the air inlet pipe 5 is externally connected to a circulating air pump. The circulating air pump inputs the gas into the heating coil 11 through the air inlet pipe 5 and discharges it through the exhaust holes. When the input gas is clean air, the oxygen content in the fermentation tank body 1 is adjusted. Hot air and cold air can also be input to adjust the temperature of the tank body in the fermentation tank body 1. The circulating air pump is used to input the gas into the heating coil 11 through the air inlet pipe 5 and discharge it through the exhaust holes. When the input gas is clean air, the oxygen content in the fermentation tank body 1 is adjusted. Hot air and cold air can also be input to adjust the temperature of the tank body in the fermentation tank body 1. The circular mixing mechanism 12 includes support rods 13 installed at the upper and lower ends of the inner cavity of the fermentation tank body 1, a circulation belt 14 sleeved on the two support rods 13, a plurality of stirring spoons 15 evenly fixed along the outer circle of the circulation belt 14, and a driving air pipe 16 connected to the heating coil 11. An open air storage cavity 20 is provided on one side of the stirring spoon 15, a stirring solenoid valve 18 is installed on the driving air pipe 16, and an output end of the driving air pipe 16 is connected to an elastic air pipe 17 corresponding to the stirring spoon 15. The stirring spoon 15 on the side close to the elastic air pipe 17 in the circular mixing mechanism 12 opens downward, and passes through The gas input from the air inlet pipe 5 is discharged through the exhaust hole on the heating coil 11. After the raw material is mixed with the gas, the oxygen content in the raw material is adjusted. The temperature of the raw material can also be adjusted by inputting gases of different temperatures, and the raw material is stirred while adjusting the temperature, so as to quickly and evenly adjust the temperature of the raw material. By controlling the switch of the stirring solenoid valve 18, the gas is discharged through the driving air pipe 16 and the elastic air pipe 17, and the discharged gas enters the gas storage chamber 20 in the stirring spoon 15. The stirring spoon 15 will gradually move upward due to the buoyancy of the gas, and drive the circulating belt 14 to rotate, and the ... the stirring spoon 15 will gradually move upward due to the buoyancy of the gas, and the stirring spoon 15 will gradually move upward due to the buoyancy of the gas, and the stirring spoon 15 will gradually move upward due to the The stirring spoon 15 is transferred to the output port of the elastic air pipe 17, and the gas is injected into the air storage cavity 20 of the stirring spoon 15 through the elastic air pipe 17, so that the other driving circulation belts 14 and the stirring spoon 15 discharged by the elastic air pipe 17 can move to stir the raw materials. The moving stirring spoon 15 has a certain blocking effect on the rising of the gas, and can also reduce the rising rate of the gas discharged through the elastic air pipe 17, thereby increasing the contact time between the gas and the raw materials, so that the raw materials can be evenly mixed with the gas, reducing the mixing dead corners of the raw materials in the fermentation tank body 1, and improving the mixing efficiency of the raw materials.

[0021] In the present embodiment, the fermentation intelligent controller 4 is installed on the outer wall of the fermentation tank body 1. The fermentation intelligent controller 4 includes an auxiliary heating module and a circulation module. The auxiliary heating module is electrically connected to the circulation module, the temperature sensor and the circulation air pump respectively. The circulation module is electrically connected to the stirring solenoid valve 18. The gas is input into the air inlet pipe 5 through the circulation air pump. The oxygen content and temperature of the raw material can be adjusted by inputting air or gas at different temperatures. When the temperature of the raw material needs to be adjusted, the temperature sensor installed on the temperature measuring rod 10 will detect the temperature data of different depths of the raw material and send it to the auxiliary heating module. The auxiliary heating module determines the temperature of different depths of the raw material according to the temperature data. When the temperature of the raw material needs to be adjusted, the auxiliary heating module controls the circulation air pump to work, and the circulation air pump inputs the gas of the specified temperature into the air inlet pipe 5. The gas passes through the heating coil 1 1, the gas moves from the raw material from bottom to top, and is discharged through the exhaust pipe 8 for recycling. During the upward movement of the gas, the thick raw material will be initially stirred. At this time, the raw material contains gas, so the thickness of the raw material will be reduced, which is convenient for the stirring spoon 15 and the circulation belt 14 to circulate and stir. The auxiliary heating module sends a circulation signal to the circulation module, and the circulation module controls the stirring solenoid valve 18 to open. The gas in the heating coil 11 will enter the driving air pipe 16 and be discharged through the elastic air pipe 17. The gas discharged through the elastic air pipe 17 drives the stirring spoon 15 to move up in turn, thereby driving multiple stirring spoons 15 to stir the raw material, improving the mixing uniformity of the raw material and the temperature-adjusting gas, quickly adjusting the raw material to the set temperature, reducing the use of stirring equipment, and reducing energy consumption and installation costs.

[0022] It is worth mentioning that see Figure 4 The side of the stirring spoon 15 away from the opening is in an arc-shaped structure, and the opening of the stirring spoon 15 is flush with the opening of the stirring spoon 15. The cross-section of the cavity of the air storage chamber 20 is in an arc-shaped structure. When the stirring spoon 15 passes through the end of the elastic air tube 17, since the elastic air tube 17 is an elastic structure, the stirring spoon 15 will move the end of the elastic air tube 17. After the elastic air tube 17 is separated from the stirring spoon 15, it will rebound into the air storage chamber 20 of the stirring spoon 15. Since the elastic air tube 17 will be inserted into the air storage chamber 20 and discharge the gas, the raw materials in the air storage chamber 20 will be discharged, so that the gas can be better injected into the air storage chamber 20. The arc-shaped air storage chamber 20 can better store the gas, and the buoyancy of the gas is used to drive the stirring spoon 15 to move upward. In addition, the stirring spoon 15 with a top arc structure reduces the resistance of the raw materials to the movement of the stirring spoon 15 during the movement process, improves the smoothness of the movement of the stirring spoon 15 and the circulating belt 14, better stirs the raw materials, and reduces the mixing dead angle of the raw materials in the fermentation tank body 1.

[0023] In addition, a plurality of circulating mixing mechanisms 12 are provided, and the plurality of circulating mixing mechanisms 12 are symmetrically arranged in the fermentation tank body 1. The elastic air pipe 17 is located on one side of the circulating mixing mechanism 12 away from the middle of the fermentation tank body 1. The output end of the elastic air pipe 17 extends to the opening of the stirring spoon 15 at the bottom of the circulating mixing mechanism 12. When the gas discharged from the elastic air pipe 17 drives the stirring spoon 15 to move, the stirring spoon 15 close to the side wall of the fermentation tank body 1 stirs and transports the raw materials to the middle of the fermentation tank body 1, thereby achieving the purpose of circulating stirring, so that the raw materials in the middle and outer wall of the fermentation tank body 1 can be evenly temperature-controlled, so that the temperature of the raw materials at different positions is kept as consistent as possible. A plurality of heating coils 11 are correspondingly provided in correspondence with the circulating mixing mechanism 12, and the plurality of heating coils 11 are all connected to the air inlet pipe 5. The gas discharged from the plurality of heating coils 11 can better control the temperature of the raw materials, thereby improving the uniformity of temperature control.

[0024] The second implementation method: Figure 6-Figure 9 The fermentation device for producing milk and soy sauce shown in the figure is different from the first embodiment in that the fermentation device also includes an auxiliary discharge mechanism, which includes a discharge stopper rod 28 plugged into the inner cavity of the down pipe 2, a driving cylinder 21 arranged parallel to the down pipe 2, a driving rod 22 plugged into the driving cylinder 21, and a discharge air pipe 6 connected to the input end of the driving cylinder 21. The driving rod 22 is fixed to the discharge stopper rod 28. The discharge stopper rod 28 is located at a discharge port 26 connected to the inner cavity of the down pipe 2 and the fermentation tank body 1. The input end of the discharge air pipe 6 is connected to the air inlet. The pipes 5 are connected, a discharge air pipe 6 is provided with a discharge solenoid valve 7, and an exhaust solenoid valve 9 is provided on the exhaust pipe 8. When the mixed raw materials need to be discharged through the bottom, gas is injected into the heating coil 11 through the air inlet pipe 5 to increase the air pressure in the inner cavity of the fermentation tank body 1, and the mixed raw materials are quickly discharged through the discharge port 26 and the down pipe 2 at the bottom. At the same time, the gas is controlled to enter the discharge air pipe 6 and the driving cylinder 21, the driving rod 22 is pushed to move, and the discharge blocking rod 28 is synchronously driven to move to connect the discharge port 26 with the inner cavity of the down pipe 2, so as to control the discharge of the mixed raw materials.

[0025] In this embodiment, a proximity switch 25 corresponding to the driving rod 22 is installed at the bottom of the fermentation tank body 1, and an auxiliary discharge module and a discharge button are also provided on the fermentation intelligent controller 4. The auxiliary discharge module is electrically connected to the auxiliary heating module, the discharge button, the discharge solenoid valve 7, the exhaust solenoid valve 9 and the proximity switch 25 respectively. When discharge is required, a discharge signal is sent to the auxiliary discharge module by pressing the discharge button, and the auxiliary discharge module sends a control signal to the auxiliary heating module. The auxiliary heating module controls the circulation air pump to inject high-pressure gas into the inner cavity of the fermentation tank body 1 through the air inlet pipe 5 and the heating coil 11. At the same time, the exhaust solenoid valve 9 is controlled to be closed so that the inner cavity of the fermentation tank body 1 maintains a certain high pressure, and the discharge solenoid valve 7 is controlled to be opened to inject gas into the driving cylinder 21. During the movement of the driving rod 22 and the discharge stop rod 28, they contact the proximity switch 25. After receiving the position signal, the proximity switch 25 sends it to the auxiliary discharge module. The auxiliary discharge module controls the discharge solenoid valve 7 to be closed. At this time, the raw materials are discharged smoothly through the discharge port 26 and the down pipe 2.

[0026] It is worth mentioning that the end of the driving cylinder 21 away from the discharge air pipe 6 is connected to the end of the lower pipe 2 away from the discharge port through the pressurized air pipe 23, and an auxiliary solenoid valve 24 is installed on the pressurized air pipe 23. The discharge stopper rod 28 is located at one end of the inner cavity of the lower pipe 2 and is provided with a pressurized through hole 27. One end opening of the pressurized through hole 27 is connected to the inner cavity of the lower pipe 2, and the other end opening of the pressurized through hole 27 corresponds to the pressurized air pipe 23. When the driving rod 22 moves to the position close to the switch 25, the inner cavity of the driving cylinder 21 is connected to the pressurized air pipe 23, and the other end of the pressurized air pipe 23 is connected to the pressurized air pipe 23. It is connected with the pressurized through hole 27, and is connected with the inner cavity of the down pipe 2 through the pressurized through hole 27. Since the mixed raw materials discharged through the down pipe 2 are relatively thick, in order to reduce the blockage, the auxiliary solenoid valve 24 can be used to control the gas in the driving cylinder 21 to be quickly filled into the down pipe 2 through the pressurized air pipe 23 and the pressurized through hole 27, and the blocked down pipe 2 is opened by high-pressure gas to reduce the blockage of the down pipe 2 during the discharge process. The driving rod 22 is located at one end of the inner cavity of the driving cylinder 21 and is equipped with an air pressure sensor 19, and the inner cavity of the down pipe 2 is equipped with a flow sensor 2 9, the auxiliary discharge module is electrically connected to the air pressure sensor 19, the flow sensor 29 and the auxiliary solenoid valve 24 respectively. When discharging through the down pipe 2, the air pressure sensor 19 detects the pressure of the gas injected into the driving cylinder 21 and feeds it back to the auxiliary discharge module. When the pressure reaches the air pressure threshold (the auxiliary discharge module is preset with the maximum air pressure in the driving cylinder 21), the discharge solenoid valve 7 is controlled to close, and the flow rate of the raw material discharged through the down pipe 2 is detected by the flow sensor 29 and fed back to the auxiliary discharge module. The auxiliary discharge module compares the flow rate of the raw material discharge with the preset flow rate (auxiliary discharge module). The discharge module is preset with a normal flow rate for raw material discharge) for comparison. When the flow rate is less than the preset flow rate, it is determined that a blockage has occurred. At this time, the auxiliary solenoid valve 24 is controlled to open, and the high-pressure gas in the driving cylinder 21 is quickly introduced into the down pipe 2, to impact the raw materials blocked in the down pipe 2 and reduce the blockage of the down pipe 2. When the air pressure in the driving cylinder 21 is reduced, the auxiliary discharge module controls the discharge solenoid valve 7 to open and the auxiliary solenoid valve 24 to close, to re-accumulate air pressure in the inner cavity of the driving cylinder 21, to prepare for the next anti-blocking operation, and to alleviate the blockage when the raw material is discharged.

[0027] In view of current practical needs, the above-mentioned implementation mode adopted in this application is not limited to the scope of protection. Various changes made within the knowledge scope of technical personnel in this field without departing from the concept of this application still fall within the scope of protection of the present invention.
