Description

Technical Field

[0001] This invention relates to the field of fermentation engineering technology, and more specifically, to a spraying device for fermenting traditional Chinese medicine soy sauce. Background Technology

[0002] The fermentation process of soy sauce is a key step in solid-state fermentation of soy sauce (especially high-salt dilute-state fermentation). It involves spraying liquid (usually the fermented sauce or brine) onto the fermentation material (a mixture of starter and brine) to regulate the fermentation environment, promote microbial metabolism, and improve the quality of soy sauce.

[0003] In existing technologies, traditional sprinkling devices mostly use a single mode to supply fermentation liquid, which cannot be specifically adjusted according to the physical state and microbial metabolic needs of the koji material at different fermentation stages. In the early stage of fermentation, the koji material has a loose structure and is easily impacted. If a sprinkling method with a large impact force is used, it will damage the koji material's shape and affect the initial colonization of microorganisms. In the middle stage of fermentation, the koji material needs deep immersion to promote microbial metabolism, but a single sprinkling mode is difficult to achieve gradual water penetration, which easily leads to uneven problems such as excessive moisture on the surface and dryness inside. In the later stage of fermentation, the koji material gradually becomes dense, and traditional sprinkling methods are difficult to penetrate the surface to achieve deep penetration and cannot effectively promote the homogenization of the mash, resulting in unstable mash quality. Meanwhile, existing sprinkling devices are mostly exposed when the machine is stopped, making them susceptible to dust and impurities from the outside, which can cause blockages or contamination of the fermentation liquid, increasing the hygiene risks during the fermentation process and affecting the stability of the quality of the fermented mash. Summary of the Invention

[0004] The purpose of this invention is to solve the problems mentioned in the background art, and thus proposes a rinsing device for fermenting Chinese herbal soy sauce.

[0005] The technical solution adopted by this invention to solve its technical problem is: A spraying device for a traditional Chinese medicine soy sauce fermentation tank includes a positioning part disposed on one side of the fermentation tank, connected to an outer shell. The outer shell is located directly above the fermentation tank and can be adjusted in position along the length and height of the tank. Several through holes are spaced apart on the bottom surface of the outer shell. A telescopic rotating part is mounted on the outer shell and connected to a liquid injection part. The liquid injection part is connected to the discharge end of the fermentation tank and can receive the fermentation liquid discharged from the tank. The liquid injection part is movably disposed on the outer shell and is also connected to a spraying part, allowing the spraying part to be adjusted in position and angle under the action of the telescopic rotating part. This enables the spraying part to exhibit three different spraying methods—spraying, dripping, and jetting—depending on the different stages of fermentation. The system has several modes: In spray mode, the watering section is positioned 1-3 cm above the fermentation tank, forming a vertical micro-flow that sprays out through the through-holes; in drip irrigation mode, the watering section is positioned 3-6 cm above the fermentation tank, forming a vertical drip that drips out through the through-holes; in jet mode, the watering section is positioned >6 cm above the fermentation tank, forming a vertical jet that sprays out through the through-holes. The injection section is also connected to a baffle plate, which is attached to the bottom surface of the inner casing and can move horizontally. The baffle plate has openings that correspond one-to-one with the through-holes. In watering mode, the openings and through-holes overlap; in shutdown mode, the openings and through-holes are misaligned, and the baffle plate blocks the through-holes.

[0006] Furthermore, the above solution includes an upper guide rail and a lower guide rail mounted on the outer shell. An upper slider is slidably fitted on the upper guide rail. The upper slider is connected to a telescopic cylinder mounted on the outer shell. A drive motor is mounted on the upper slider. The drive motor is fixedly connected to a transmission component and rotatably connected to a moving plate via a rotating shaft. Both the transmission component and the moving plate are connected to the liquid injection part. The moving plate is connected to the lower slider slidably mounted on the lower guide rail.

[0007] Furthermore, the above solution includes two inner components symmetrically arranged on the outer shell. One inner component contains an injection component that is movably connected to the transmission component and the moving plate, and the other inner component contains a support component that is movably connected. The pouring part is located between the injection component and the support component.

[0008] Furthermore, the above solution includes a circular tube disposed on the outer shell, with both ends of the circular tube open and a plurality of ball bearings installed inside it to form a rolling channel inside the circular tube, and the liquid injection component and the support component are each connected to the corresponding rolling channel.

[0009] Furthermore, the above solution includes a liquid injection component that is connected to a rolling channel. The liquid injection component is fixedly connected to a transmission component and rotatably connected to a moving plate. The outer end of the liquid injection component extends to the outside of the moving plate and is connected to an inlet pipe for connecting to the discharge end of the fermentation tank via a rotary joint. The inner end of the liquid injection component extends into the outer shell and is connected to a U-shaped tube for communicating with the sprinkling section. A first spring is provided between the U-shaped tube and the round tube. The first spring is sleeved on the outside of the liquid injection component to play a buffering role during the horizontal position adjustment of the sprinkling section. A solenoid valve is installed on each of the two passages of the U-shaped tube to realize the injection of fermentation liquid into the sprinkling section.

[0010] Furthermore, the above solution includes a mounting rod that is connected to the rolling channel. The inner end of the mounting rod extends into the housing and is fixedly connected to the pouring section. A second spring is sleeved on the outside of the mounting rod. The second spring is located between the round tube and the pouring section. The outer end of the mounting rod extends into the housing and is rotatably connected to a connecting plate. A sliding rod is provided on the connecting plate. The sliding rod is horizontally slidably disposed on the housing. The inner end of the sliding rod extends into the housing and is fixedly connected to a baffle.

[0011] Furthermore, the above solution includes a watering pipe connected to a U-shaped tube and a mounting rod. Inside the watering pipe, a spray chamber and a jet chamber, each connected to two passages of the U-shaped tube, are formed by a partition. The spray chamber is equipped with atomizing nozzles matching the number of through holes. In spray mode, the atomizing nozzles are positioned one-to-one with the through holes, and their corresponding solenoid valves open, allowing the fermentation liquid to be injected into the spray chamber. The jet chamber is equipped with jet nozzles matching the number of atomizing nozzles and oriented in the same direction. In jet mode, the jet nozzles are positioned one-to-one with the through holes, and their corresponding solenoid valves open, allowing the fermentation liquid to be injected into the jet chamber. In drip irrigation mode, the atomizing nozzles and jet nozzles are aligned with the side wall of the outer casing, and both solenoid valves open simultaneously, allowing the fermentation liquid to be injected into the outer casing and drip through the through holes.

[0012] Furthermore, in the above scheme, in the spray mode, the atomizing nozzle is set vertically in the initial state; in the drip irrigation mode, the irrigation pipe is rotated 90° and the atomizing nozzle and the jet nozzle are set horizontally; in the jet mode, the irrigation pipe is rotated 180° and the jet nozzle is set vertically.

[0013] Furthermore, the outer end of the mounting rod extends to the outside of the connecting plate and is connected to an auxiliary part. In drip irrigation mode, the auxiliary part is located below the outer shell to disperse the fermentation liquid dripping through the through hole.

[0014] Furthermore, the above solution includes a support rod connected to the mounting rod, a distribution plate on the support rod, the distribution plate being located below the outer casing in drip irrigation mode, and the distribution plate having several drip holes.

[0015] Compared with the prior art, the beneficial effects of the present invention are: This invention employs three irrigation modes—spraying, dripping, and jetting—and applies them in stages corresponding to the early, middle, and late stages of fermentation. This precisely matches the physical state (loose → semi-dense → dense) and microbial metabolic needs (surface colonization → internal growth → homogenization) of the fermenting material at different stages of fermentation. The spraying mode in the early stage provides a mild environment for initial microbial colonization; the dripping mode in the middle stage solves the problem of uneven deep wetting of the fermenting material; and the jetting mode in the later stage achieves deep penetration of the fermenting material and promotes homogenization of the fermented mash, significantly improving fermentation efficiency. The staged irrigation modes directly target the characteristics of the fermenting material at different stages, avoiding problems such as fermenting material damage, uneven wetting, and insufficient deep penetration caused by traditional single irrigation methods, effectively improving the stability of the fermented mash quality. Simultaneously, the baffle design completely blocks the orifices when the machine is stopped, preventing external dust and impurities from entering, avoiding blockage of the orifices and contamination of the fermentation liquid, cutting off the source of contamination, reducing hygiene risks, and further ensuring the quality of the fermented mash.

[0017] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention. The present invention will be further described with reference to the accompanying drawings and embodiments: A spraying device for fermenting Chinese herbal soy sauce, as shown in the attached document. Figure 1 and attached Figure 2 As shown, the device includes a positioning part 1 located on one side of the fermentation tank. The positioning part 1 is connected to a housing 2, which is positioned directly above the fermentation tank and can be adjusted in position along the length and height of the fermentation tank. The positioning part 1 can employ common movement methods such as existing lead screw movement structures and linear slide rail structures. This movement method is mainly used to adjust the position of the device in the Y-axis and Z-axis coordinate directions in the pouring mode, ensuring that the pouring range covers the target area. This device will not be described in detail here. The bottom surface of the housing 2 has several through holes 21 distributed at intervals. These through holes 21 are the key channels for the fermentation liquid to be poured into the fermentation tank. A telescopic rotating part 3 is installed on the housing 2. The telescopic rotating part 3 is connected to an injection part 4, which is connected to the discharge end of the fermentation tank and can receive the fermentation liquid discharged from the fermentation tank. The injection part 4 is movably mounted on the housing 2.

[0018] The injection unit 4 is also connected to the rinsing unit 5, so that the position and angle of the rinsing unit 5 can be adjusted under the drive of the telescopic rotating unit 3. This allows the rinsing unit 5 to present three different rinsing modes—spraying, dripping, and jetting—according to different stages of fermentation, in order to meet the needs of the koji material at different fermentation stages. In spray mode, the sprinkling section 5 is positioned 1-3 cm above the fermentation tank. At this time, the fermentation liquid introduced by the injection section 4 is sprayed out through the through hole 21, forming a vertical microflow. This microflow can ensure that the surface of the fermented material inside the fermentation tank is evenly moistened, while effectively avoiding impact and damage to the fermented material due to excessive impact force.

[0019] In drip irrigation mode, the sprinkling section 5 is positioned 3-6 cm above the fermentation tank. At this time, the fermentation liquid introduced by the injection section 4 falls through the through hole 21 in a dripping manner, forming a vertical drip. This sprinkling method can slowly and continuously supply water to the koji material, meet the wetting needs of the koji material, and promote the growth and metabolism of microorganisms inside the koji material.

[0020] In the jetting mode, the sprinkling section 5 is positioned >6cm above the fermentation tank. At this time, the fermentation liquid introduced by the injection section 4 is ejected through the through hole 21 in the form of a vertical jet. The jet has a strong impact force and can penetrate deep into the koji material to meet the deep penetration requirements of the koji material. At the same time, the jet can also form turbulence in the koji material, promote the homogenization of the mash, and make the quality of the mash more uniform and stable.

[0021] In addition, the liquid injection section 4 is also connected to a baffle 6. The baffle 6 is attached to the bottom surface of the inner shell 2 and can move horizontally. The baffle 6 has openings 61 that match the through holes 21 one by one. In the rinsing mode, the openings 61 correspond perfectly with the through holes 21 to ensure that the fermentation liquid can pass smoothly through the through holes 21 for rinsing and to ensure the normal operation of the rinsing mode. In the shutdown mode, the openings 61 and the through holes 21 are misaligned, and the baffle 6 can completely block the through holes 21.

[0022] During implementation, this device, through its graded design of the pouring mode, can precisely match the characteristics of the starter culture at each stage of soy sauce fermentation. In the early stage of fermentation (1-7 days): a spray mode (height 1-3cm) is adopted. The fermentation liquid forms a vertical microflow through the through hole 21. At this time, the structure of the koji material is loose and easily impacted. The microflow can evenly moisten the surface layer and avoid damaging the shape of the koji material, providing a mild environment for the initial colonization of microorganisms.

[0023] Mid-fermentation stage (8-21 days): Switch to drip irrigation mode (height 3-6cm). The fermentation liquid falls slowly in the form of drips. At this stage, the koji material needs to be deeply soaked to promote microbial metabolism. The "continuous low volume" characteristic of dripping can ensure that water gradually penetrates into the interior of the koji material, avoiding the problem of uneven drying of the surface and the interior.

[0024] Late fermentation stage (over 22 days): A jetting mode (height > 6cm) is adopted, and the fermentation liquid forms a high-impact jet. In the later stage, the koji material is dense, and the jet can penetrate the surface and go deep into the interior. At the same time, turbulence is formed to promote the homogenization of the mash and solve the problems of insufficient deep penetration and uneven quality of mash.

[0025] This "stage-customized" sprinkling method directly targets the physical state (loose → semi-dense → dense) and microbial metabolic needs (surface colonization → internal growth → homogenization) of the koji material at different fermentation stages, significantly improving fermentation efficiency and the stability of the sauce mash quality.

[0026] Furthermore, through the design of the baffle 6, the opening 61 on the baffle 6 corresponds perfectly with the through hole 21 of the outer shell 2 during operation, ensuring smooth passage of the fermentation liquid without affecting the rinsing efficiency. In the shutdown state, the baffle 6 moves horizontally to misalign the opening 61 with the through hole 21, completely blocking the through hole 21. This effectively prevents external dust and impurities from entering the interior of the outer shell 2, avoiding blockage of the through hole 21 or contamination of the fermentation liquid, cutting off the source of contamination, reducing the hygiene risks during the fermentation process, and ensuring the stability of the quality of the fermented mash.

[0027] For the above scheme, please refer to the appendix for details. Figure 3 As shown, the telescopic rotating part 3 includes an upper guide rail 31 and a lower guide rail 32 disposed on the outer shell 2. An upper slider 33 is slidably fitted on the upper guide rail 31. The upper slider 33 is connected to a telescopic cylinder 34 disposed on the outer shell 2, so that the telescopic cylinder 34 operates to drive the upper slider 33 to move linearly along the upper guide rail 31. A drive motor 35 is mounted on the upper slider 33. The drive motor 35 is fixedly connected to a transmission component 37 and rotatably connected to a moving plate 38 through a rotating shaft 36. The transmission component 37 adopts one of the existing technologies of belt drive, gear drive or chain drive. This invention will not elaborate further on this. In addition, both the transmission component 37 and the moving plate 38 are connected to the liquid injection part 4, and the moving plate 38 is connected to the lower slider 39 slidably disposed on the lower guide rail 32.

[0028] In this design, the telescopic rotating part 3 achieves the telescopic movement and angular rotation of the spraying part 5 through the coordinated operation of the mechanical structure, thereby precisely adjusting the position and angle of the spraying part 5 to complete different stages of spraying operations. When it is necessary to adjust the telescopic position of the injection part 4, the telescopic cylinder 34 on the outer shell 2 is activated. The operation of the telescopic cylinder 34 will drive the upper slider 33 connected to it to move linearly along the upper guide rail 31. Since the upper slider 33 is connected to the injection part 4 through the drive motor 35, transmission component 37, etc., and the moving plate 38 is connected to the lower slider 39 on the lower guide rail 32, the movement of the upper slider 33 will synchronously drive the spraying part 5 to telescopically extend and retract in the linear direction, realizing the horizontal position adjustment of the spraying part 5 to adapt to the needs of the spraying mode. To adjust the angle of the spraying part 5, the drive on the upper slider 33 is activated. The motor 35 drives the transmission component 37 to rotate via the rotating shaft 36. The transmission component 37 then drives the liquid injection section 4 to rotate. The moving plate 38, being rotatably connected to the rotating shaft 36, does not rotate and only serves a supporting function, ensuring that the fermentation liquid can be poured through the through hole 21 on the outer shell 2 at a suitable angle to meet the pouring needs of different koji material areas. In actual use, the telescopic movement driven by the telescopic cylinder 34 and the rotational movement driven by the drive motor 35 can be coordinated. By precisely controlling the operation of both, the pouring section 5 can be adjusted to a preset position and angle, allowing the fermentation liquid introduced by the pouring section 5 to smoothly enter the outer shell 2 and then be precisely poured onto the koji material in the fermentation tank through the through hole 21 in a spray, drip, or jet mode, ensuring the smooth progress of the pouring operation at each fermentation stage.

[0029] For the above scheme, please refer to the appendix for details. Figure 3 As shown, the injection section 4 includes two inner members 41 symmetrically arranged on the outer shell 2. One inner member 41 is movably disposed in which an injection member 42 connected to the transmission member 37 and the moving plate 38 is movably disposed. The other inner member 41 is movably connected in which a support member 43 is connected. The pouring section 5 is disposed between the injection member 42 and the support member 43.

[0030] Specifically, refer to the appendix Figure 4 As shown, the inner connector 41 includes a circular tube 411 disposed on the outer shell 2. The circular tube 411 is open at both ends and has a plurality of balls 412 installed inside it to form a rolling channel inside the circular tube 411. The liquid injection component 42 and the support component 43 are each connected to the corresponding rolling channel.

[0031] Specifically, refer to the appendix Figure 3As shown, the liquid injection component 42 includes a liquid guide tube 421 connected to the rolling channel. The liquid guide tube 421 is fixedly connected to the transmission component 37 and rotatably connected to the moving plate 38. The outer end of the liquid guide tube 421 extends to the outside of the moving plate 38 and is connected to an inlet tube 423 for connecting to the liquid discharge end of the fermentation tank through a rotary joint 422. The inner end of the liquid guide tube 421 extends into the outer shell 2 and is connected to a U-shaped tube 424 for communicating with the sprinkling section 5. A first spring 425 is provided between the U-shaped tube 424 and the round tube 411. The first spring 425 is sleeved on the outside of the liquid guide tube 421 to play a buffering role during the horizontal position adjustment of the sprinkling section 5. A solenoid valve 426 is installed on each of the two passages of the U-shaped tube 424 to realize the injection of fermentation liquid into the sprinkling section 5.

[0032] Specifically, refer to the appendix Figure 3 As shown, the support member 43 includes a mounting rod 431 that is connected to the rolling channel. The inner end of the mounting rod 431 extends into the housing 2 and is fixedly connected to the pouring part 5. A second spring 432 is sleeved on the outside of the mounting rod 431. The second spring 432 is located between the round tube 411 and the pouring part 5. The outer end of the mounting rod 431 extends into the outside of the housing 2 and is rotatably connected to a connecting plate 433. A sliding rod 434 is provided on the connecting plate 433. The sliding rod 434 is horizontally slidably disposed on the housing 2. The inner end of the sliding rod 434 extends into the housing 2 and is fixedly connected to the baffle 6.

[0033] In this design, the injection unit 4, through the coordinated operation of the inner connector 41, the injection component 42, and the support component 43, achieves stable transmission of the fermentation liquid, flexible adjustment of the sprinkling unit 5, and linkage control of the baffle 6. During use, the inner connector 41 is composed of a round tube 411 with ball bearings 412, forming a rolling channel for the liquid guide tube 421 of the injection component 42 and the mounting rod 431 of the support component 43 to connect. The ball bearings 412 convert sliding friction into rolling friction, reducing component wear and ensuring smooth movement of the injection component 42 and the support component 43 during linear horizontal movement and rotation angle adjustment. In the injection component 42, the liquid guide tube 421 is connected to the inlet tube 423 through a rotary joint 422 to receive the fermentation liquid, which is then transported to the sprinkling unit 5 through the U-shaped tube 424. When the drive motor 35 drives the transmission component 37 to rotate, the liquid guide tube 421 rotates synchronously within the rolling channel, cooperating with the rotary joint. 422 avoids pipe entanglement and enables adjustment of the rinsing angle; when the telescopic cylinder 34 moves the moving plate 38, the liquid guide pipe 421 moves linearly along the rolling channel to complete the horizontal movement adjustment; the solenoid valve 426 on the U-shaped pipe 424 can control the injection of fermentation liquid; the first spring 425 buffers the impact during the movement and protects the components, ensuring stable liquid transmission, precise control and compatibility with compound motion; the mounting rod 431 of the support member 43 symmetrically supports the rinsing part 5 with the liquid guide pipe 421 to prevent it from tilting; when it moves synchronously with the rinsing part 5, the connecting plate 433 drives the sliding rod 434 to slide, thereby linking the baffle 6 to open and close the through hole 21; the second spring 432 and the first spring 425 form a double buffer to enhance stability; its symmetrical support design improves the structural stability; the mechanical linkage does not require additional drive, simplifying the structure and ensuring consistent operation.

[0034] For the above scheme, please refer to the appendix for details. Figure 3 As shown, the sprinkling section 5 includes a sprinkling pipe 51 connected to the U-shaped tube 424 and the mounting rod 431. Inside the sprinkling pipe 51, a spray chamber 53 and a jet chamber 54, each communicating with two passages of the U-shaped tube 424, are formed by a partition 52. Each spray chamber 53 is equipped with an atomizing nozzle 55, the number of which matches the number of through holes 21. In spray mode, the atomizing nozzle 55 corresponds one-to-one with each through hole 21, and the corresponding solenoid valve 426 opens, injecting the fermentation liquid into the spray chamber 5. 3. Inside; wherein, the jet chamber 54 is provided with jet nozzles 56 in the same number and direction as the atomizing nozzles 55. In jet mode, the jet nozzles 56 are arranged one-to-one with the through holes 21, and the corresponding solenoid valves 426 are opened to realize the injection of fermentation liquid into the jet chamber 54; wherein, in drip irrigation mode, the atomizing nozzles 55 and jet nozzles 56 are aligned with the side wall of the outer shell 2, and the two solenoid valves 426 are opened simultaneously to realize the injection of fermentation liquid into the outer shell 2 and dripping through the through holes 21.

[0035] It is worth noting that in spray mode, the atomizing nozzle 55 is set to the initial vertical position; in drip irrigation mode, the irrigation pipe 51 is rotated 90°, and the atomizing nozzle 55 and the jet nozzle 56 are set to the horizontal position; in jet mode, the irrigation pipe 51 is rotated 180°, and the jet nozzle 56 is set to the vertical position.

[0036] In this design, the irrigation section 5 is centered around a rotatable (0° / 90° / 180°) irrigation pipe 51. Inside, a partition 52 separates an independent spray chamber 53 and a jet chamber 54, which are connected to two passages of a U-shaped pipe 424 and equipped with atomizing nozzles 55 and jet nozzles 56 respectively. The mode switching is achieved by the rotation angle and the linkage with the solenoid valve 426. When the rotation angle is 0°, the atomizing nozzle 55 is aligned with the through hole 21, and the spray chamber 53 supplies liquid to form a microflow (spray mode). When the rotation angle is 90°, the two nozzles are aligned with the side wall of the outer shell 2, and the liquid is supplied to both chambers at the same time and buffered by the side wall to form a drip (drip irrigation mode). When the rotation angle is 180°, the jet nozzle 56 is aligned with the through hole 21, and the jet chamber 54 supplies liquid to form a jet (jet mode).

[0037] In the above scheme, considering that the opening of the through hole 21 is relatively large in the drip irrigation mode, in order to improve the drip irrigation effect, therefore, refer to 5 and Appendix Figure 6 As shown, the outer end of the mounting rod 431 extends to the outside of the connecting plate 433 and is connected to an auxiliary part 7. In drip irrigation mode, the auxiliary part 7 is located below the outer shell 2 to disperse the fermentation liquid dripping through the through hole 21.

[0038] Specifically, the auxiliary part 7 includes a support rod 71 connected to the mounting rod 431. The support rod 71 is provided with a distribution plate 72. In drip irrigation mode, the distribution plate 72 is located below the outer casing 2, and the distribution plate 72 is provided with a plurality of drip holes 731.

[0039] In the solution, under drip irrigation mode, the support rod 71 moves in conjunction with the mounting rod 431 to position the distribution plate 72 below the outer shell 2, receiving the fermentation liquid dripping through the through hole 21 and dispersing it through the drip hole 731. This solution can specifically address the problem of concentrated drip irrigation caused by the large opening of the through hole 21, improve the uniformity of drip irrigation, and require no additional drive to move in conjunction with the mounting rod 431. The simple structure effectively enhances the wetting effect of the fermentation material under drip irrigation mode. The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of protection claimed by the present invention.
