Abstract
Description
TECHNICAL FIELD
[0001] The present application belongs to the technical field of enzymatic hydrolysis of Rhizoma Polygonati, and particularly relates to an enzymatic hydrolysis device for Rhizoma Polygonati. BACKGROUND
[0002] In the deep processing of Rhizoma Polygonati, enzymatic hydrolysis is a key step for effectively breaking the cell wall and extracting active ingredients. However, the existing industrial enzymatic hydrolysis equipment and process have several technical bottlenecks, which restrict the improvement of production efficiency and product quality.
[0003] Traditional Rhizoma Polygonati is made into Rhizoma Polygonati by nine times of steaming and drying, which produces toxic substances 5-hydroxymethyl furfural. When Rhizoma Polygonati decoction pieces are soaked in water for drinking, the dissolution rate of Rhizoma Polygonati polysaccharide is low, and long-term consumption is needed to achieve the effect. Modern enzymatic hydrolysis technology uses biological enzymes to catalytically decompose the structural components and biological macromolecules of Rhizoma Polygonati cell walls under mild conditions. Not only can it more effectively release active ingredients, but also can avoid the generation of harmful substances from the source, while better preserving the true flavor of medicinal materials.
[0004] The cell wall structure of Rhizoma Polygonati material itself is dense and rich in anti-degradation components such as cellulose and lignin. Conventional single enzyme treatment is difficult to achieve sufficient wall breaking, resulting in generally low dissolution rate of active ingredients such as Rhizoma Polygonati polysaccharide, causing resource waste.
[0005] Secondly, in the existing enzymatic hydrolysis tank, Rhizoma Polygonati is in a solid-liquid mixed state during enzymatic hydrolysis. Due to the lack of effective dynamic mixing and anti-deposition mechanism, Rhizoma Polygonati residues are prone to deposit on the bottom of the tank under the action of gravity, forming clumps, leading to uneven mass transfer. The utilization of enzymatic hydrolysis space is not sufficient, and the upper material in the same batch has completed enzymatic hydrolysis, while the bottom still has Rhizoma Polygonati residues that have not been fully treated, which seriously affects the uniformity and overall efficiency of enzymatic hydrolysis.
[0006] In addition, the existing equipment generally does not have the function of online monitoring and automatic control of key process parameters, mainly relying on manual experience for intermittent adjustment. Not only is the labor intensity large, but it is also difficult to guarantee the consistency and process stability between batches, and cannot meet the needs of continuous and standardized production.
[0007] Therefore, it is necessary to develop an efficient, stable and intelligent Rhizoma Polygonati enzymatic hydrolysis device to solve the above problems. SUMMARY
[0008] To solve the above problems in the prior art, the present application provides an enzymatic hydrolysis device for Rhizoma Polygonati, which solves the problem that the enzymatic hydrolysis space of the existing enzymatic hydrolysis tank is usually fixed, and Rhizoma Polygonati often deposits at the bottom of the enzymatic hydrolysis tank due to gravity, resulting in insufficient utilization of the enzymatic hydrolysis tank, Rhizoma Polygonati in the upper part has completed enzymatic hydrolysis, while Rhizoma Polygonati in the bottom still exists in the form of flakes, which further leads to uneven enzymatic hydrolysis and affects the efficiency of Rhizoma Polygonati enzymatic hydrolysis.
[0009] The object of the present application can be achieved by the following technical solutions: A rhizoma polygonati enzymatic hydrolysis device, comprising a tank body, a filter disc, a stirring assembly, a transmission assembly and a rotating shaft; the tank body is hollow inside and the rotating shaft is vertically arranged at the center of the inside of the tank body, the filter disc is fixedly connected with the transmission assembly and coaxially arranged with the rotating shaft; when the rotating shaft rotates counterclockwise, the transmission assembly drives the stirring assembly to move downward synchronously in a spiral manner, and the filter disc rotates relative to the rotating shaft; when the rotating shaft rotates clockwise, the filter disc is clamped with the rotating shaft through the transmission assembly, and the stirring assembly rotates relative to the rotating shaft to stir the rhizoma polygonati in the same horizontal plane.

[0021] To further illustrate the technical means and effects of the present invention in achieving its intended purpose, the following detailed description of the specific implementation methods, structures, features, and effects of the present invention, in conjunction with the accompanying drawings and preferred embodiments, is provided.
[0022] like Figures 1-4 As shown, a Polygonatum sibiricum enzymatic hydrolysis device includes a tank 1, a filter plate 2, a stirring assembly 3, a transmission assembly 4, and a rotating shaft 5. The tank 1 is hollow inside, and the rotating shaft 5 is vertically arranged at the center of the tank 1. The filter plate 2 is fixedly connected to the transmission assembly 4 and is coaxial with the rotating shaft 5. When the rotating shaft 5 rotates counterclockwise, the transmission assembly 4 drives the stirring assembly 3 to move downward in a synchronous spiral, and the filter plate 2 rotates relative to the rotating shaft 5. When the rotating shaft 5 rotates clockwise, the filter plate 2 is engaged with the rotating shaft 5 through the transmission assembly 4, and the stirring assembly 3 rotates relative to the rotating shaft 5, stirring Polygonatum sibiricum on the same horizontal plane. Specifically, the rotating shaft 5 is driven by a drive device (such as a motor) to rotate counterclockwise. At this time, the clamping block 41 in the transmission assembly 4 retracts radially under the drive of the linkage mechanism, so that its inner thread is firmly engaged with the outer thread of the rotating shaft 5. Since the clamping block 41 is fixedly connected to the filter disc 2 and the stirring assembly 3, the threaded pair converts the rotational motion of the rotating shaft 5 into the downward linear motion of the entire stirring assembly 3. Therefore, the stirring assembly 3 slowly rotates counterclockwise with the shaft while moving downward in a spiral motion, penetrating the material layer inside the tank. During this process, the filter disc 2 is disengaged from the rotating shaft 5 through the transmission assembly 4 on it, so the filter disc 2 moves synchronously with the stirring assembly 3.
[0023] When downward movement is not required, the drive unit drives the rotating shaft 5 to rotate clockwise. The instant the rotation of the rotating shaft 5 changes direction, the transmission assembly 4 engages with the rotating shaft 5, achieving a rigid connection. At this time, the filter disc 2 locks with the rotating shaft 5 and begins to rotate clockwise synchronously with the shaft at its current height. Simultaneously, the clamping block 41 in the transmission assembly 4 extends radially under the drive of the connecting rod, disengaging its internal thread from the external thread of the rotating shaft 5. The power connection between the stirring assembly 3 and the rotating shaft 5 is thus severed, causing the stirring component 3 to rotate with the filter disc 2 and stir the Polygonatum sibiricum, promoting the enzymatic hydrolysis reaction.
[0024] In summary, this embodiment achieves the dual functions of the stirring component 3—spiral downward movement to break up bottom deposits and horizontal rotation for mixing—through bidirectional rotation control, effectively solving the problem of uneven enzymatic hydrolysis caused by the deposition and agglomeration of Polygonatum odoratum materials. Its dynamic mixing mechanism significantly improves space utilization and mass transfer efficiency, promotes cell wall disruption and dissolution of active ingredients, while enhancing process controllability and batch stability, thus improving the overall enzymatic hydrolysis effect and product quality.
[0025] In one embodiment, the transmission assembly 4 includes a clamping block 41 that is radially retractable and extendable by a connecting rod. The clamping block 41 is machined with external threads on the rotating shaft 5. At least two radially retractable clamping blocks 41 are arranged circumferentially around the rotating shaft 5, typically two or three, to maintain force balance. The inner side of the clamping block 41 is machined with an internal thread that matches the external thread of the rotating shaft 5. The outer side of each clamping block 41 is connected to a linkage mechanism, which can be operated by a unified control ring or similar drive device. This is implemented using existing technology and will not be described in detail here. When it is necessary to stir the bottom sediment by lowering the stirring assembly 3, all clamping blocks 41 are driven by the linkage mechanism to retract radially towards the center (i.e. towards the rotating shaft 5) in sync, so that their internal threads are firmly engaged with the external threads of the rotating shaft 5. At this time, the rotating shaft 5 is started to rotate counterclockwise. Utilizing the transmission characteristics of the threaded pair, the clamping blocks 41 that are engaged together will drive the entire stirring assembly 3 fixed to them to move smoothly and uniformly downward in a spiral motion. After the downward movement is completed, when it is necessary to switch modes, the linkage mechanism pulls the clamping blocks 41 to extend radially outward, so that their internal threads are disengaged from the rotating shaft 5, thereby interrupting the power transmission. The retractable characteristics of the clamping blocks 41 enable the same rotating shaft 5 to transmit both rotational torque (for horizontal stirring) and linear displacement (for downward movement), realizing dual use of one shaft and greatly simplifying the transmission structure.
[0026] In one embodiment, the transmission assembly 4 includes a mounting groove 42, an elastic element 43, a snap-fit block 44, and a plurality of snap-fit grooves 45; on the shaft of the rotating shaft 5, a plurality of regularly shaped snap-fit grooves 45, such as rectangular grooves, are arranged in a circumferential or axial array; a mounting groove 42 is provided inside the hole in the center of the filter disc 2 that mates with the rotating shaft 5; an elastic element 43 and a snap-fit block 44 are placed in the mounting groove 42; the shape of the snap-fit groove 45 matches the snap-fit groove 45, such as spherical or wedge-shaped. In its natural state, the preload of the elastic element 43 continuously pushes the locking block 44 outward, causing a portion of it to protrude from the opening of the mounting groove 42. When the rotating shaft 5 rotates clockwise and needs to engage with the filter disc 2, the protruding portion of the locking block 44, guided by the surface of the rotating shaft 5, is pressed back into the mounting groove 42 until it moves to a position aligned with a certain locking groove 45. At this point, the elastic element 43 pushes the locking block 44 into the locking groove 45, producing a click sound, completing the mechanical interlock, thereby rigidly connecting the filter disc 2 and the rotating shaft 5. This causes the filter disc 2 to rotate at the height of the currently engaged locking groove 45, simultaneously driving the rotating shaft 5 to rotate counterclockwise. When the force acting on the inclined surface of the locking block 44 is applied, it will squeeze the locking block 44 out of the locking groove 45 and compress the spring, so that the locking block 44 continues to slide on the smooth surface of the shaft, thereby releasing the connection and achieving separation. Furthermore, the elastic element 43 can be understood as a spring sheet, and a torsion spring is installed at its connecting shaft. The abutting parts at both ends of the torsion spring abut against the spring sheet and the mounting groove 42 respectively, so as to realize the rotation and compression of the spring sheet. With the rotating shaft 5 as the center, the elastic element 43 is located outside the locking block 44, and the side wall of the mounting groove 42 is ninety degrees, which limits the maximum rotation angle of the locking block 44 to 90 degrees, so as to avoid the locking block 44 from rotating too much and causing unstable locking with the mounting groove 42.
[0027] In addition, the snap-fit block 44 is installed in the mounting slot 42 via an electrically driven rotating shaft. When the filter disc 2 needs to rise, the rotating shaft is driven to rotate, causing the snap-fit block 44 to rotate and be confined in the mounting slot 42. At this time, the rotating shaft 5 rotates clockwise, and the snap-fit block 44 will not interfere with or connect with the rotating shaft 5. At the same time, the two clamping blocks 41 are driven to extend and clamp the rotating shaft 5, so that the clamping blocks 41 are threadedly connected to the rotating shaft 5, and the clamping blocks 41 are driven to rotate and rise under the rotation of the rotating shaft 5.
[0028] During the enzymatic hydrolysis of Polygonatum, the Polygonatum residue deposited at the bottom of the tank tends to stick together, forming a dense, sheet-like agglomerated layer. Traditional rigid stirring paddles, when rotating, primarily exert macroscopic shearing and pushing forces on the material, but their force is holistic and cannot effectively penetrate and pry open the bottommost agglomerated layer. A gap usually exists between the stirrer and the tank bottom, easily creating a stirring "dead zone," preventing the bottommost material from being turned over and the enzymatic hydrolysate from being fully mixed. In one embodiment, the stirring assembly 3 includes several stirring rods 31. At the bottom of each stirring rod 31, multiple tendrils 32 are flexibly connected via hinges or ball joints. These tendrils 32 can be made of corrosion-resistant and wear-resistant flexible materials such as food-grade silicone or special engineering plastics. Their length is designed to ensure that when the stirring rod 31 descends to its lowest point, the tendrils 32 can cover the tank bottom area. When the stirring assembly 3 spirals downwards under the drive of the transmission assembly 4, these tendrils 32 will first contact and insert into the bottom Polygonatum sediment layer. As the stirring rod 31 continues to move downwards and rotate, the tendrils 32 will randomly and irregularly bend, swing, and whip under the resistance of the material. This dynamic and flexible disturbance, like "fingers," can cleverly insert into the gaps of the flaky Polygonatum sibiricum, prying, breaking, and tearing it apart, thereby completely destroying the agglomerated structure and ensuring that the deposited Polygonatum sibiricum residue is fully mixed with the enzymatic hydrolysate. The effective destruction of the bottom agglomerates by the tendrils 32 ensures that all materials in the tank, including the bottommost Polygonatum sibiricum, are exposed and fully contacted with the enzyme. This fundamentally solves the problem of uneven enzymatic hydrolysis caused by deposition, improving product yield and quality consistency. Compared to simply increasing the overall stirring power to try to agitate the bottom, this highly targeted and flexible disturbance method achieves better agitation with less energy consumption. In traditional enzymatic hydrolysis equipment, operators often rely on fixed time intervals or experience to determine whether enzymatic hydrolysis is complete, making it impossible to perceive the actual state of the sediment at the bottom of the tank in real time. If the process ends too early, the bottom Polygonatum will not be completely hydrolyzed, affecting the yield; if the bottom is left to fully hydrolyze, the upper material will have been over-hydrolyzed, affecting product quality and wasting time and energy. Furthermore, the space of the hydrolysis tank is fixed, making it impossible to dynamically optimize the reaction area based on the real-time reduction of material. In one embodiment, a control system is also included, with the rotating shaft 5 connected to the control system. At least one density sensor is installed on each of the several tentacles 32, used to detect the density of the Polygonatum residue and upload the data to the control system. A filter disc 2 divides the tank 1 into an upper dissolution space and a lower enzymatic hydrolysis space, and the filter disc 2 is electrically connected to the control system. Specifically, the sensor monitors the density changes of the surrounding Polygonatum material in real time and uploads the data to the central control system. When the detected density value is continuously lower than the set threshold, it is determined that the solid Polygonatum in that area has been basically enzymatically hydrolyzed. The control system will issue a command to drive the filter plate 2 to slowly move down, thereby actively reducing the volume of the lower enzymatic hydrolysis space. This makes the remaining, incompletely enzymatically hydrolyzed Polygonatum solids more concentrated, and the concentration of the enzymatic hydrolysate relatively increases, thereby accelerating the final reaction rate until it is completely completed.
[0029] By monitoring and adjusting in real time, we ensured that every batch of Polygonatum could be enzymatically hydrolyzed, avoiding batch-to-batch differences caused by human error or process fluctuations, and significantly improving product quality. Secondly, we greatly improved production efficiency and equipment utilization. By reducing the enzymatic hydrolysis space to concentrate the treatment of residual solids, we accelerated the completion of the reaction and shortened the overall production cycle of a single batch. More batches can be produced in the same amount of time, thus increasing production capacity.
[0030] In a conventional enzymatic hydrolysis tank, the interior of the tank 1 is a uniform space where the hydrolyzed solution and the incompletely hydrolyzed solid material are mixed together. If the solution needs to be removed, it can only be discharged as a whole through the outlet. This results in the incompletely hydrolyzed solid being discharged as well, either causing waste or requiring additional filtration equipment for post-processing, increasing the process and cost. At the same time, this mixed state makes it impossible for the equipment to process materials with different degrees of hydrolysis separately. In one embodiment, the filter plate 2 is provided with several through holes that penetrate the main body. The through holes are used to filter the hydrolyzed Polygonatum solution to the upper dissolution space.
[0031] In one embodiment, the stirring rod 31 is vertically arranged with the filter plate 2 and is located at the lower part of the filter plate 2. The filter plate 2 is a disc-shaped component horizontally arranged inside the tank 1. Its outer edge is sealed to the inner wall of the tank 1 and can slide relative to it. Specifically, the filter holes of the filter plate 2 allow the solution formed after enzymatic hydrolysis to pass freely, while effectively blocking un-hydrolyzed or hydrolyzed solid substances such as Polygonatum residue and particles. When the stirring component 3 is working below and Polygonatum is hydrolyzed, the resulting solution will pass through these through holes and be naturally filtered into the upper dissolution space under the action of gravity or slight pressure difference, thereby realizing automatic and continuous solid-liquid separation in the tank. Unlike the traditional one-time separation after the reaction is completed, the through holes designed in this way allow the enzymatic reaction and solution separation to proceed simultaneously. The products of the completed reaction can leave the reaction zone at any time. This avoids the product inhibition effect and frees up space for continuous reaction, improving the overall efficiency.
[0032] The activity of enzymes (such as amylase and protease) is highly dependent on the pH of the reaction environment, and their optimal pH range is usually very narrow. Traditional methods mainly rely on manual timed sampling and offline detection, or only installing sensors at a fixed position in tank 1. Sampling and detection have a huge time delay and cannot reflect real-time changes, which may lead to missing the optimal time to add regulators. Secondly, sensors at fixed positions cannot effectively monitor the true pH environment of the high-concentration material zone at the bottom, where the pH value may differ greatly from that of the supernatant. Manual operation cannot achieve precise continuous control, which can easily cause pH fluctuations, deviating from the optimal activity range of the enzyme, resulting in low enzymatic hydrolysis efficiency, prolonged reaction time, increased enzyme dosage, and even affecting the quality and yield of the final product.
[0033] In one embodiment, at least one pH concentration detection sensor is provided among the plurality of tentacles 32; the pH concentration detection sensor is communicatively connected to the control system and is used to detect the pH value of the material in the enzymatic hydrolysis space in real time; the control system compares the real-time data with the set value, and once the pH value is detected to deviate from the optimal range, it will immediately generate a control command to automatically start the acid or alkali solution addition system connected to the enzymatic hydrolysis space of the tank 1. By precisely controlling the start and stop and flow rate of the addition pump, the system can dynamically and accurately adjust and stably maintain the pH value of the reaction environment within the preset optimal range, creating the best conditions for the efficient action of the enzyme.
[0034] In one embodiment, at least one of the tentacles 32 is further provided with a viscosity detection sensor; the viscosity detection sensor is communicatively connected to the control system; when the viscosity detection sensor detects that the real-time viscosity of the material continuously exceeds a first preset threshold, the rotating shaft 5 is controlled to rotate alternately clockwise and counterclockwise, driving the stirring assembly 3 to perform reciprocating shearing disturbance on the bottom deposition area; based on the data fed back by the density detection sensor, the filter plate 2 is controlled to move downward to dynamically reduce the operating volume of the lower enzymatic hydrolysis space; when the received viscosity data continuously exceeds the first preset threshold, the system determines that a high viscosity phenomenon has occurred in the bottom deposition area. At this time, the control system no longer executes a single rotation mode, but issues a command to control the drive motor to make the rotating shaft 5 rotate alternately clockwise and counterclockwise. This alternating rotation drives the stirring assembly 3 and its tentacles 32 to perform a strong reciprocating shearing disturbance on the high viscosity deposition area. This dynamic, reversed shearing force can more effectively destroy the gel structure and reduce the local viscosity.

Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present invention. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present invention without departing from the scope of the present invention shall still fall within the scope of the present invention.
