Description

Technical Field

[0001] This utility model relates to the technical field of soy sauce production, and in particular to a soy sauce extraction device. Background Technology

[0002] Soy sauce is made primarily from plant protein and carbohydrates. Through the action of microbial enzymes, it is hydrolyzed into various amino acids and sugars. After complex biochemical changes, it develops a unique color, aroma, flavor, and texture, which helps to stimulate appetite. During the production process, soy sauce needs to be extracted. There are two methods for extracting soy sauce: one is to transfer the mash to another pool, rinse it with water, and collect the soy sauce; the other is to soak and extract the oil in the original pool, which involves adding water to the original pool and letting the mash soak.

[0003] However, the existing device is not convenient for staff to disassemble the filter screen, which can easily lead to clogging or even damage after prolonged use, thus affecting the normal use of the device. Utility Model Content

[0004] In order to improve the problem mentioned above that the existing device is inconvenient for workers to disassemble the filter screen, and the filter screen is prone to clogging or even damage after long-term use, thus affecting the normal use of the device, this utility model provides a soy sauce extraction device.

[0005] This utility model provides a soy sauce extraction device, which adopts the following technical solution:

[0006] A soy sauce extraction device includes a fermentation tank, a liquid outlet pipe connected to the bottom of the fermentation tank, a liquid outlet valve provided on the liquid outlet pipe, a filter screen installed at the bottom of the inner cavity of the fermentation tank, a locking block connected to the left end of the filter screen, a locking groove for inserting and engaging with the locking block on the left side wall of the inner cavity of the fermentation tank, a pull plate installed at the right end of the filter screen extending out of the fermentation tank, and a top cover installed on the top of the fermentation tank.

[0007] A lifting assembly is provided between the top cover and the fermentation tank. A liquid guide pipe is rotatably connected to the middle of the top cover. A driving assembly is provided between the liquid guide pipe and the top cover. The bottom of the liquid guide pipe extends into the interior of the fermentation tank and is equipped with a spray holder. Several nozzles are connected to the bottom of the spray holder. A heating box is installed at the top left end of the top of the top cover. A suction assembly is provided between the heating box and the liquid guide pipe. A salt replenishment pipe is connected to the top of the heating box. A water inlet pipe is connected to the upper left side of the heating box.

[0008] By adopting the above technical solution, after the fermented mash matures in the fermentation tank, hot brine is added to the inside of the liquid guide pipe through the suction component and sprayed downwards through the spray seat and nozzle. The mash is soaked in hot brine, and at the same time, the liquid outlet valve is opened to release oil. The opening degree of the liquid outlet valve is controlled at 1 / 3, the flow rate is 500-1000L / h, and the brine addition rate is slightly greater than the oil release rate to keep the mash from sinking. After the brine soaking is completed, the opening degree of the liquid outlet valve is controlled at 1 / 2, and hot water is added. The top cover is removed from the top of the fermentation tank through the lifting component. At this time, hot water is added to the inside of the fermentation tank. During the hot water heating process, the water level should not exceed 20cm above the surface of the mash. Soy sauce is discharged from the fermentation tank through the liquid outlet pipe. During the discharge process, the residue is intercepted by the filter screen. When there is a lot of residue on the filter screen, the worker pulls the pull plate to the right. The pull plate moves the filter screen to the right, thereby removing the filter screen from the inside of the fermentation tank and cleaning the residue.

[0009] Optionally, a locking assembly is provided between the pull plate and the fermentation tank. The locking assembly includes a fixed plate, which is installed at the lower right side of the fermentation tank.

A rectangular block is connected to the bottom of the movable plate, and a rectangular groove is opened on the top of the pull plate to engage with the rectangular block.

[0010] By adopting the above technical solution, when it is necessary to release the locking effect of the rectangular block on the pull plate, the rubber ball is pulled up. The rubber ball drives the movable plate to move upward through the movable rod and squeezes the positioning spring. The movable plate moves up and drives the rectangular block to move upward until the rectangular block separates from the rectangular groove.

[0011] Optionally, a second heating plate is connected to both sides of the inner wall of the fermenter, a second temperature detector is installed at the upper end of the right side wall of the inner cavity of the fermenter, and a controller is installed at the lower end of the left side of the fermenter. The output end of the second temperature detector is electrically connected to the input end of the controller, and the output end of the controller is electrically connected to the input end of the second heating plate.

[0012] By adopting the above technical solution, the liquid inside the fermenter is heated by the second electric heating plate, and the temperature value is sensed and transmitted to the controller by the second temperature detector. When the temperature value reaches the set value, the controller turns off the second electric heating plate.

[0013] Optionally, a first heating plate is installed at the bottom of the inner wall of the heating box, and a first temperature detector is installed at the lower end of the left side wall of the inner cavity of the heating box. The output end of the first temperature detector is electrically connected to the input end of the controller, and the output end of the controller is electrically connected to the input end of the first heating plate.

[0014] By adopting the above technical solution, the liquid inside the first temperature detector is heated by the first heating plate, and the temperature value is sensed and transmitted to the controller by the first temperature detector. When the temperature value reaches the set value, the controller turns off the first heating plate.

[0015] Optionally, a sliding assembly is provided between the spray base and the top cover. The sliding assembly includes a slider, which is installed on the top of the spray base. An annular slide rail is provided at the bottom of the top cover, and the annular slide rail is slidably connected to the slider.

[0016] By adopting the above technical solution, when the spray holder rotates, it can drive the slider to slide inside the annular slide rail, thereby making the spray holder more stable during rotation.

[0017] Optionally, the bottom of the top cover and the top of the fermentation tank are provided with positioning components. The positioning components include positioning blocks, which are connected to the edge of the bottom of the top cover. The top of the fermentation tank is provided with a positioning groove that is inserted and matched with the positioning blocks.

[0018] By adopting the above technical solution, the positioning block and positioning groove are connected and matched, so that the fermentation tank and the top cover fit more closely.

[0019] Optionally, the lifting assembly includes two sets of support plates, which are respectively installed at the lower ends of both sides of the fermentation tank. A lifting cylinder is installed on the top of each set of support plates, and a connecting plate is installed on the top of each set of lifting cylinders. The two connecting plates are respectively fixedly connected to both ends of the top cover.

[0020] By adopting the above technical solution, the extension and retraction of the lifting cylinder can drive the connecting plate to move up and down.

[0022] By adopting the above technical solution, when the motor starts, it drives the small gear to rotate through the rotating shaft. The rotation of the small gear drives the large gear to rotate, and the rotation of the large gear drives the liquid guide tube to rotate, which in turn drives the spray base and the nozzle to rotate.

[0023] Optionally, the suction assembly includes a suction pump, which is installed at the right end of the top of the heating chamber. The input end of the suction pump is connected to a suction pipe, and the end of the suction pipe facing away from the suction pump extends into the bottom of the inner cavity of the heating chamber. The output end of the suction pump is connected to a delivery pipe, and the end of the delivery pipe facing away from the suction pump extends into the interior of the liquid guide pipe.

[0024] By adopting the above technical solution, when the suction pump starts, the suction pipe is raised to extract the brine inside the heating tank and transport it to the inside of the liquid guide pipe through the delivery pipe.

[0025] In summary, this utility model has at least one of the following beneficial effects:

[0026] By using a combination of a filter screen, slots, blocks, and a pull plate, the filter screen removes soy sauce residue from the soy sauce. The slots and blocks also allow for easy removal of the filter screen from the fermentation tank periodically to clean the residue, minimizing the accumulation of residue and preventing clogging. This improves the practicality of the device.

[0027] The system utilizes a combination of rubber balls, movable rods, fixed plates, positioning springs, movable plates, rectangular blocks, and rectangular grooves to lock the pull plate, ensuring a tighter connection between the pull plate and the fermentation tank and effectively preventing soy sauce leakage due to separation of the pull plate from the fermentation tank.

[0028] Through the coordinated setup of the water inlet pipe, fermentation tank, second temperature detector, nozzle, spray base, top cover, liquid guide pipe and suction assembly, and multiple soakings in brine and hot water, the effective components of soy sauce, namely amino acid nitrogen and salt, are extracted at a high rate.

[0042] Please refer to the attached diagram in the instruction manual. Figure 1 and Figure 3A suction assembly 21 is provided between the heating chamber 23 and the liquid guide pipe 20. The suction assembly 21 includes a suction pump 2102, which is fixedly installed at the right end of the top of the heating chamber 23. The input end of the suction pump 2102 is fixedly connected to a suction pipe 2103, and the end of the suction pipe 2103 facing away from the suction pump 2102 extends into the bottom of the inner cavity of the heating chamber 23. The output end of the suction pump 2102 is fixedly connected to a delivery pipe 2101, and the end of the delivery pipe 2101 facing away from the suction pump 2102 extends into the interior of the liquid guide pipe 20. When the suction pump 2102 is started, it raises the suction pipe 2103 to extract brine from inside the heating chamber 23 and delivers it to the interior of the liquid guide pipe 20 through the delivery pipe 2101. A salt replenishment pipe 22 is fixedly connected to the top of the heating chamber 23, and a water inlet pipe 1 is fixedly connected to the upper left side of the heating chamber 23.

[0043] Working principle: During use, after the fermented mash matures in the fermentation tank 9, water and salt are added to the interior of the heating box 23 through the water inlet pipe 1 and the salt replenishment pipe 22. The first electric heating plate 3 is turned on to heat the interior of the heating box 23. The temperature value inside the heating box 23 is sensed by the first temperature detector 2. The sensed temperature value signal is transmitted to the controller. When the temperature value inside the heating box 23 reaches the set value, that is, the liquid inside the heating box 23 is heated to above 95°C, the controller turns off the first electric heating plate 3.

[0044] Then, the suction pump 2102 is started. The suction pump 2102 draws brine through the suction pipe 2103 and delivers it to the inside of the liquid guide pipe 20 through the delivery pipe 2101. At the same time, the motor 1901 is started. When the motor 1901 is working, it drives the small gear 1903 to rotate through the rotating shaft 1902. The rotation of the small gear 1903 drives the large gear 1904 to rotate. The rotation of the large gear 1904 drives the liquid guide pipe 20 to rotate. The hot brine is sprayed downward through the spray seat 16 and the nozzle 15 to soak the mash. At the same time, the liquid outlet valve 11 is opened to release oil. The opening degree of the liquid outlet valve 11 is controlled at 1 / 3, the flow rate is 500-1000L / h, and the brine addition speed is slightly greater than the oil release speed to keep the mash from sinking.

[0045] When heating the brine, oil is added to the bottom of fermentation tank 9, and the heating of the brine is stopped. The oil is then stopped being added to the bottom to ensure that the mash is soaked between the brine heating and the brine heating. This process is repeated. After the brine soaking is completed, the liquid outlet valve 11 is opened to 1 / 2 and hot water above 95°C is added. At this time, the lifting cylinder 502 is extended. The extension of the lifting cylinder 502 drives the connecting plate 501 to move upward. The upward movement of the connecting plate 501 drives the top cover 18 to move upward, so that the top cover 18 is removed from the top of fermentation tank 9. At this time, hot water is added to the inside of fermentation tank 9. During the heating process, the water level should not exceed 20cm above the surface of the mash. If it exceeds this level, no more hot water should be added. Otherwise, the excessive water pressure will compress the mash and slow down the oil dripping speed until it is finally dried out.

[0046] Soy sauce is discharged from fermentation tank 9 through outlet pipe 10. During the discharge process, soy sauce residue is intercepted by filter screen 6. When a large amount of soy sauce residue accumulates on filter screen 6, the worker pulls up rubber ball 2401. Rubber ball 2401 drives movable plate 2405 upward through movable rod 2402 and squeezes positioning spring 2404. Movable plate 2405 moves upward, driving rectangular block 2406 upward until rectangular block 2406 separates from rectangular groove 2407. At this time, the locking effect of rectangular block 2406 on pull plate 12 is released. Then, pull plate 12 is pulled to the right. Pull plate 12 drives filter screen 6 to move to the right, so that filter screen 6 can be removed from the inside of fermentation tank 9 and the soy sauce residue can be cleaned.

[0047] The above are all preferred embodiments of this utility model, and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape and principle of this utility model should be covered within the scope of protection of this utility model.
