Description

Technical Field

[0001] The utility model is a preparation device for nine-processed polygonatum sibiricum, specifically relating to a device for preparing traditional Chinese medicine that requires multiple repeated processes, and belongs to the field of biopharmaceuticals. Background Art

[0002] Polygonatum sibiricum is a perennial herb of the family Asparagaceae, commonly known as "chicken head ginseng". The roots, leaves, and flowers of polygonatum sibiricum can all be eaten, and its rhizome is used medicinally. However, its raw roots are spicy and irritating to the throat. Usually, the polygonatum sibiricum in traditional Chinese medicine is also called nine-processed polygonatum sibiricum, which is a cooked product prepared by the traditional nine-steaming and nine-sunning process from the rhizome of polygonatum sibiricum. Polygonatum kingianum, polygonatum sibiricum, or polygonatum cyrtonema are mostly used, and it has the effects of nourishing yin and promoting fluid production, nourishing the kidney and moistening the lungs, tonifying qi and strengthening the spleen, etc.

[0003] Although the traditional nine-steaming and nine-sunning process for making polygonatum sibiricum is not complicated, it requires nine repeated steaming and sunning processes, a total of 18 processes in 9 times, all of which are manually repeated operations. This not only wastes manpower but also has the problems of low efficiency and long time consumption. In addition, the traditional process mostly uses manual or semi-manual control of the time, temperature of the steaming process, and the sunshine time of the sunning process. Among them, the sunning process is most affected by the weather (sunshine conditions). In addition, due to the individual differences in the mastery of the production process by the production personnel, the quality instability of the produced nine-processed polygonatum sibiricum is likely to occur, directly affecting the final efficacy of the finished nine-processed polygonatum sibiricum.

[0004] Over the years, various pharmaceutical enterprises have conducted a large number of studies on the traditional nine-steaming and nine-sunning process of nine-processed polygonatum sibiricum and made more beneficial improvements. On the basis of the traditional steaming and sunning processes, two additional processes of soaking and moistening are added, so that the effects of the prepared nine-processed polygonatum sibiricum have different effects according to the different added adjuvants, showing different medicinal values and dietetic values. With the rapid development of technology, the production of nine-processed polygonatum sibiricum has gradually changed from manual operation to mechanical operation, which not only greatly improves the production efficiency of nine-processed polygonatum sibiricum but also realizes standardized production and improves the quality stability of the finished nine-processed polygonatum sibiricum.

[0005] In the prior art, the preparation methods related to the nine-steamed and nine-boiled process of Polygonatum sibiricum and the preparation devices of related preparation methods mostly focus on solving the related problems of the steaming and sun-drying processes. There has not yet been a device that can simultaneously meet the requirements of the four processes of soaking, steaming, stewing (moistening), and sun-drying (i.e., drying) in the same device. Therefore, manual participation is still required to complete the above four processes, resulting in low efficiency; or a method of stacking 9 sets of devices that can each complete three of the processes (steaming, moistening, and sun-drying) is adopted, that is, a method of sequentially connecting multiple devices with the functions of completing three different processes in series. Although it eliminates the disadvantages of manual operation and low efficiency, its structure is complex. Setting multiple devices with repeated functions requires a large amount of manufacturing materials, and the medicine needs to flow through multiple (at least 18) process devices, which also consumes a large amount of energy, resulting in waste of resources. In addition, whether it is the traditional preparation process or the modern preparation process, during the steaming and stewing stages of the preparation of nine-processed Polygonatum sibiricum, there has always been a problem of a large amount of medicinal juice flowing away with the steam. Although multiple technical solutions for medicinal juice recovery have emerged successively in the prior art, it is still impossible to ensure the full infiltration and complete recovery of Polygonatum sibiricum.

[0006] For example: The utility model patent with the application number 202223517923.3 discloses a Chinese medicine baking and steaming integrated device, which includes a baking and steaming box body at the lower part and a spraying and drying mechanism at the upper part. The baking and steaming box body and the spraying and drying mechanism are snap-connected; the baking and steaming box body includes a shell. A first motor is arranged at the center of the inner bottom of the shell. The output shaft end of the first motor is detachably installed with a medicinal material container. The center of the inner bottom of the medicinal material container is fixedly installed with a first support. The first support is a hollow circular tube. A placement tray is sleeved on the first support. A first heating wire is installed on one side inside the shell, and an air outlet is opened at the upper opening on the other side inside the shell. The spraying and drying mechanism includes a liquid recovery mechanism, a spraying mechanism, and a drying mechanism. By simultaneously operating the liquid recovery mechanism, the spraying mechanism, and the drying mechanism arranged on the bottom plate, the utility model solves the problem that the medicinal juice flowing out during the drying process cannot be sprayed onto the surface of the medicinal materials, and the medicinal juice can fully infiltrate the Polygonatum sibiricum medicinal materials and then be steamed again, and can continuously perform nine steaming and nine sun-drying on the medicinal materials, improving the steaming and sun-drying efficiency of the medicinal materials.

[0007] For another example, a patent for invention with the application number 202210350764.8 discloses a medicinal herb steaming machine for preparing yellow-fleshed polygala root by the nine-steaming and nine-boiling process and its usage method, including: a circulating tunnel, which is annular and composed of 9 steaming and moistening sections and 9 drying sections distributed alternately and connected, and one of the drying sections is set as the access box; the steaming and moistening section, whose side wall is of a double-layer hollow structure and has steam holes arranged on its inner wall; the drying section, in which a number of first heat dissipation pipes are arranged at intervals, and both ends of the first heat dissipation pipes are respectively connected to the side walls of the adjacent steaming and moistening sections; a circular opening is arranged on the lower side of the circulating tunnel. In the present invention, once the yellow-fleshed polygala root enters the circulating tunnel, it needs to pass through nine steaming and moistening sections and nine drying sections, so that the yellow-fleshed polygala root must go through nine times of steaming and moistening and drying before being sent out, ensuring the integrity of the processing technology, avoiding the influence of skimping due to poor management, and ensuring the medicinal properties of the prepared yellow-fleshed polygala root.

[0008] In summary, the prior art has not provided a technical solution to solve the above or related problems. Summary of the Utility Model

[0009] The purpose of the present utility model is to provide a device for preparing nine-processed yellow-fleshed polygala root. Through the liftable first lifting mechanism arranged on the inner wall of the cabinet body, the height of the medicine storage part can be adjusted, and it is respectively coordinated with the dryer arranged in the drying part and the heater arranged in the liquid storage part to realize the arbitrary switching of the four processes of soaking, steaming, stewing, and drying in the closed space of the cabinet body, thereby solving the problem that the above four processes cannot be completed in the same device in the prior art and avoiding the waste of relevant resources.

[0010] The present utility model is realized through the following technical solutions:

[0011] A device for preparing nine-processed yellow-fleshed polygala root includes a cabinet body and a drying part and a liquid storage part arranged in the cabinet body. The drying part is arranged at the top of the cabinet body and is provided with a dryer, the liquid storage part is arranged at the bottom of the cabinet body and is provided with a heater, a movable medicine storage part is arranged in the liquid storage part, the medicine storage part is used for storing medicines, and it is provided with through holes. A first lifting mechanism for lifting the medicine storage part between the drying part and the liquid storage part is arranged on the inner wall of the cabinet body, and a second opening for the medicine storage part to enter and exit the cabinet body is arranged on the cabinet body corresponding to the position between the drying part and the liquid storage part.

[0012] Furthermore, a movable partition board is arranged between the drying part and the liquid storage part, and the partition board and the cabinet body above it, including the drying part, form a space for drying the medicine storage part.

[0013] Furthermore, the first lifting mechanism is a telescopic rod controlled by a driving motor. The driving motor is fixedly arranged on the outer wall of the top of the cabinet body. The fixed end of the telescopic rod is connected to the driving motor, and the telescopic end passes through the cabinet body and is connected to the medicine storage part, and drives the medicine storage part to lift in the cabinet body.

[0014] Further, a chute for cooperating with the lifting of the medicine storage part is also provided in the cabinet body. A slider is arranged in the chute, and the slider is fixedly connected to the side wall of the medicine storage part.

[0015] Further, a limiting device for limiting the stopping position of the medicine storage part is also provided on the inner wall of the cabinet body corresponding to the drying part.

[0016] Further, the cabinet body is also provided with a condenser. The air inlet of the condenser is arranged between the drying part and the liquid storage part, and an exhaust fan for sucking air into the condenser is provided. The air outlet of the condenser is arranged above its air inlet and is communicated with the drying part, and its liquid discharge port is arranged below its air inlet and is communicated with the liquid storage part.

[0017] Further, the condensate of the condenser is the medicinal liquid used for the preparation of polygonatum sibiricum, and the medicinal liquid is conveyed to the liquid storage part through the condensate pipe of the condenser.

[0018] Further, a pressure controller is arranged on the inner wall of the cabinet body corresponding to the drying part.

[0019] Further, a first temperature sensor, a humidity sensor and a pressure sensor are arranged in the drying part, and a liquid level sensor and a second temperature sensor are arranged in the liquid storage part.

[0020] Further, a cabinet door with a monitoring window is arranged at the second opening.

[0021] Compared with the prior art, the utility model has the following advantages and beneficial effects:

[0022] (1) By arranging a drying part and a liquid storage part in the cabinet body, arranging a first lifting mechanism between the drying part and the liquid storage part, and arranging a medicine storage part lifted by the lifting mechanism, the medicine storage part can be soaked in the liquid storage part, steamed and simmered between the liquid storage part and the drying part, and dried in the drying part, so that the four processes of preparing nine-processed polygonatum sibiricum are realized in the cabinet body. And the above four processes can be cycled through the lifting of the liquid storage part and the cooperation of the heater and the dryer, so that the liquid storage part can realize the cycle of the above four processes only in the cabinet body. At the same time, in the steaming and simmering link, the cabinet body is in a sealed state, effectively avoiding the loss of medicinal juice along with the steam caused by high-temperature steaming and simmering.

[0023] (2) By arranging a movable partition between the drying part and the liquid storage part, the partition plays a role of isolation, which can not only prevent the steam with medicinal juice from dissipating during steaming and simmering, but also avoid the influence of the steam generated by high temperature or natural evaporation on the drying effect of the medicine in the drying part when drying.

[0024] (3) By arranging the first lifting mechanism with a telescopic rod controlled by a driving motor, the working efficiency of the device is improved, and at the same time, the situation of scalding caused by high temperature or inconvenient manual operation is avoided.

[0025] (4) The utility model can make the lifting of the medicine storage part more stable by arranging a sliding groove in the cabinet body that cooperates with the lifting of the medicine storage part and a sliding block arranged therein and connected to the side wall of the medicine storage part. The sliding groove guides the lifting of the medicine storage part. Even if the first lifting mechanism fails, it can ensure that the medicine storage part will not overturn. At the same time, the medicine storage part can also be manually pulled up along the sliding groove to assist in the lifting of the medicine storage part.

[0026] (5) The utility model ensures that the medicine storage part can stay at the set position by arranging a limiting device on the inner wall of the cabinet body, thereby preventing the medicine storage part from sliding down into the liquid storage part during the steaming, simmering and drying stages, so as to ensure the realization of the functions in the above stages.

[0027] (6) The utility model arranges a condenser, sets the air inlet of the condenser between the drying part and the liquid storage part, and then arranges an exhaust fan that sucks air into the condenser at the air inlet of the condenser, which can promote the air flow speed in the cabinet body, thereby improving the drug drying efficiency. In addition, the high-temperature and high-humidity air in the cabinet body is condensed by the condenser to realize liquid-gas separation, and then the dried gas and the condensed liquid are respectively released to the drying part and the liquid storage part through the exhaust port arranged above the air inlet and the drain port arranged below the air inlet, realizing the gas circulation and liquid circulation in the cabinet body. In addition, using the principle that the liquid flows downward after condensation, not only can the part of the medicinal juice evaporated with the water vapor flow back to the liquid storage part for soaking the medicine, thus solving the problem of the loss of the medicinal juice with the steam, but also effectively avoiding the situation that the condensed liquid is blown out or carried out of the exhaust port by the rapidly circulating gas, further improving the drug drying efficiency.

[0028] (7) The utility model sets the condensate of the condenser as the medicinal liquid used for preparing polygonatum sibiricum, and transports the medicinal liquid to the liquid storage part through the condensate pipe of the condenser. On the one hand, it can supplement the liquid in the liquid storage part, and on the other hand, it realizes the preheating of the medicinal liquid through the heat exchange process of the condenser, realizing the recycling of energy and playing the role of energy conservation and environmental protection.

[0029] (8) The utility model fixes and arranges a pressure controller on the inner wall of the cabinet body corresponding to the drying part to adjust the pressure in the cabinet body.

[0030] (9) The utility model arranges a first temperature sensor, a humidity sensor and a pressure sensor in the drying part to monitor the temperature, humidity and pressure in the drying part, and arranges a liquid level sensor and a second temperature sensor in the liquid storage part to monitor the liquid level height and temperature in the liquid storage part.

[0031] (10) The utility model arranges a cabinet door with a monitoring window at the second opening to enable the preparation state of polygonatum sibiricum to be viewed at any time.

[0032] The utility model has a simple structure and is easy to operate. Not only does the first lifting mechanism enable the medicine storage part to complete the four processes of soaking, steaming, stewing, and drying of polygonatum sibiricum preparation in a cycle through height adjustment within the space of the cabinet body, but also the gas circulation and liquid circulation within the cabinet body are realized through the condensation method, which speeds up the drug drying efficiency and effectively avoids the loss of medicinal juice (i.e., active ingredients) with water vapor during the steaming and stewing processes. In addition, the settings of the heater, dryer, and pressure controller enable the temperature, humidity, and pressure of each part within the cabinet body to meet the requirements of each stage during the polygonatum sibiricum preparation process, so that each process can be carried out as required, thereby further ensuring the quality of the prepared polygonatum sibiricum.

[0037] The following further describes the utility model in detail with reference to the embodiments, but the embodiments of the utility model are not limited thereto.

[0038] Embodiment:

[0039] As Figures 1 to 3 shown in the structure, this embodiment discloses a device for preparing nine-process polygonatum sibiricum, including a cabinet body 1 and a drying part 2 and a liquid storage part 3 arranged in the cabinet body 1;

[0040] Drying part 2: Arranged at the top of the cabinet body 1 and provided with a dryer, and a first temperature sensor, a temperature sensor, and a pressure sensor are arranged in the drying part 2;

[0041] Liquid storage part 3: Arranged at the bottom of the cabinet body 1 and provided with a heater, and a movable medicine storage part 4, a liquid level sensor, and a second temperature sensor are arranged in the liquid storage part 3;

[0042] Medicine storage part 4: Used for storing medicines, and is provided with through holes for enabling medicinal liquid (i.e., adjuvants) or steam to enter the medicine storage part 4. The medicine storage part 4 in this embodiment has a single-layer structure, and the preparation efficiency can also be improved by adopting a multi-layer structure;

[0043] The first lifting mechanism: It is used for lifting between the medicine storage part 4, the drying part 2 and the liquid storage part 3. It is arranged on the inner wall of the cabinet body 1, and the medicine storage part 4 is detachably connected to the first lifting mechanism;

[0044] The second opening: It is used for the medicine storage part 4 to enter and exit the cabinet body 1. It is set on the cabinet body 1 corresponding to the position between the drying part 2 and the liquid storage part 3. A cabinet door is provided at the second opening.

[0045] The monitoring window: It is set on the cabinet door and is used to view the status and changes during the preparation process of polygonatum sibiricum, so as to better control the quality of the prepared nine-processed polygonatum sibiricum;

[0046] The pressure controller: It is fixedly set on the inner wall of the cabinet body 1 corresponding to the drying part 2 and is used to adjust the pressure above the liquid storage part 3.

[0047] Preparatory work before use: Add a sufficient amount of liquid medicine (i.e., auxiliary materials) with a set concentration into the medicine storage part 4, and check the functional devices such as the first lifting mechanism, the dryer, and the heater to make them work properly.

[0048] Usage method:

[0049] Step 1: Place the polygonatum sibiricum in the medicine storage part 4;

[0050] Step 2: Open the cabinet door, put the medicine storage part 4 into the cabinet body 1 through the second opening, connect it to the first lifting mechanism, and then close the cabinet door;

[0051] Step 3: Start the first lifting mechanism to lower the medicine storage part 4 into the liquid storage part 3, and ensure that the polygonatum sibiricum in the medicine storage part 4 is completely immersed in the liquid medicine in the liquid storage part 3. Then, stop the first lifting mechanism;

[0052] Step 4: Turn on the heater to keep the liquid medicine in the liquid storage part 3 at an appropriate temperature, and at the same time, the polygonatum sibiricum should remain immersed in the liquid medicine. This is the soaking stage;

[0053] Step 5: After soaking, start the first lifting mechanism again to raise the medicine storage part 4 to a set height above the liquid storage part 3 and stop. Then adjust the heater to increase the heating temperature to keep the temperature in the cabinet body 1 above the liquid storage part 3 at the medicine steaming temperature. This is the medicine steaming stage;

[0054] Step 6: After medicine steaming, turn off the heater to keep the medicine in the cabinet body 1 in this moistening state. At this time, the temperature in the cabinet body 1 gradually decreases, which is the moistening stage;

[0055] Step 7: After moistening, start the first lifting mechanism again to raise the medicine storage part 4 to the drying part 2, stop the first lifting mechanism, and then turn on the dryer until the humidity in the cabinet body 1 reaches the set humidity. This is the drying stage;

[0056] Step 8: After drying is completed, close the dryer;

[0057] Step 9: Repeat Steps 3 to 8. After the eighth repetition of Steps 3 to 8, start the first lifting mechanism, lower the medicine storage part 4 to the second opening, then open the cabinet door, and take out the medicine storage part 4 and the prepared nine-processed polygonatum sibiricum inside.

[0058] After use: It is necessary to detect the liquid level and concentration of the liquid medicine in the liquid storage part 3 to adjust it to the set liquid level and concentration, and check whether there are any faults in the functional devices such as the first lifting mechanism, dryer, and heater for subsequent use.

[0059] If there is a fault in the functional device, it should be repaired. Before repair, the liquid medicine in the liquid storage part 3 should be transferred and recycled first to prevent impurities from falling into the liquid medicine during the troubleshooting of the functional device, which may affect the efficacy of the prepared nine-processed polygonatum sibiricum; after the repair is completed, the inside of the cabinet body 1 should be cleaned before use.

[0060] This embodiment has a simple structure and is convenient to use in the preparation process of nine-processed polygonatum sibiricum. However, some deficiencies that can be further optimized are still found during the use process. Therefore, to ensure the quality and preparation efficiency of the prepared nine-processed polygonatum sibiricum, a series of targeted improvements have been made to address these deficiencies.

[0061] As Figures 1 to 3 shown, in this embodiment, soaking, steaming, stewing, and drying are completed in the common space of the cabinet body 1. The medicine storage part 4 needs to move back and forth between the drying part 2 and the liquid storage part 3 in the cabinet body 1. Thus, it can be seen that the drying part 2 and the liquid storage part 3 must be connected, that is, the integrated design inside the cabinet body 1.

[0062] In this embodiment, there are still problems affecting the drying efficiency:

[0063] 1. The steam formed during the medicine steaming stage will enter the drying part 2 and condense on the inner wall of the cabinet body 1 corresponding to the drying part 2 when it cools during the stewing (moistening) stage, which will increase the drying time and thus reduce the drying efficiency.

[0064] The liquid medicine in the liquid storage part 3 will partially evaporate and turn into steam and disperse into the cabinet body 1 (including the drying space) during the drying process due to the integrated design, and there is no barrier between the drying part and the liquid storage part, thus reducing the drying efficiency.

[0065] Furthermore, as Figure 2 and Figure 3As shown in the figure, to solve the above problem of affecting the drying efficiency, a movable partition 6 is provided between the drying section 2 and the liquid storage section 3. The partition 6 and the cabinet 1 above it, including the drying section 2, form a space for drying the medicine storage section 4, which blocks the steam of the liquid medicine from entering the drying space, thereby improving the drying efficiency of this embodiment. Among them, the installation height of the partition 6 is preferably such that the space below it can meet the requirements of the three stages of soaking, steaming, and stewing as a whole, so as to reduce the number (or frequency) of times the medicine storage section 4 is lifted and lowered, thereby achieving the purpose of reducing energy consumption. Of course, the above purpose can also be achieved by setting two movable partitions. However, for the purpose of improving efficiency and saving energy, in this embodiment, the best setting method is to set only one partition 6, that is, the cabinet 1 is divided into upper and lower two spaces by the partition 6. The upper space is only used for drying the medicine, and the lower space is used for the three processes of soaking, steaming, and stewing. This not only improves the drying efficiency but also effectively reduces the energy consumption of the first lifting mechanism by reducing the number of times the medicine storage section 4 is lifted and lowered.

[0066] After adopting this optimized solution, the initial state of the partition 6 is the open state, and the operation of the partition 6 is added during the use of this embodiment, which involves steps three and seven in the usage method. The specific situation is as follows

[0067] 1. The changed step three: Start the first lifting mechanism to lower the medicine storage section 4 into the liquid storage section 3, and ensure that all the polygonatum sibiricum in the medicine storage section 4 is soaked in the liquid medicine in the liquid storage section 3. Then, stop the first lifting mechanism and close the partition 6.

[0068] 2. The changed step seven: After the stewing is completed, open the partition 6, start the first lifting mechanism again to raise the medicine storage section 4 to the drying space above the partition 6, then stop the first lifting mechanism, close the partition 6, and then turn on the dryer until the humidity in the cabinet 1 reaches the set humidity. At this time, it is the drying stage.

[0069] Furthermore, as Figure 2 and Figure 3 shown, to solve the problem of low work efficiency caused by manual operation of the first lifting mechanism, the first lifting mechanism is set as a telescopic rod 10 controlled by a driving motor 9. The driving motor 9 of the telescopic rod 10 is fixedly arranged on the outer wall of the top of the cabinet 1. After the telescopic rod 10 is connected to the driving motor 9, it is fixed on the top of the cabinet 1. The telescopic end of the telescopic rod 10 passes through the cabinet 1 and is connected to the medicine storage section 4. The telescopic end of the telescopic rod 10 drives the medicine storage section 4 to lift and lower in the cabinet 1. The connection between the driving motor 9 and the telescopic rod 10 and the driving of its telescopic are all conventional settings and belong to the prior art, so they will not be elaborated here.

[0070] Furthermore, as Figure 2 and Figure 3As shown in the figure, in order to make the lifting of the medicine storage part 4 more stable, a sliding groove 7 for cooperating with the lifting of the medicine storage part 4 is further provided in the cabinet body 1. A sliding block 8 is arranged in the sliding groove 7, and the sliding block 8 is fixedly connected to the side wall of the medicine storage part 4. The arrangement of the sliding groove 7 not only plays a guiding role in the lifting of the medicine storage part 4, but also ensures that the medicine storage part 4 can still lift along the sliding groove 7 when the first lifting mechanism fails, playing an auxiliary lifting role.

[0071] Usage method:

[0072] Step 1: Place the polygonatum sibiricum in the medicine storage part 4;

[0073] Step 2: Open the cabinet door, put the medicine storage part 4 into the cabinet body 1 through the second opening, and connect it to the telescopic end of the telescopic rod 10, and then close the cabinet door;

[0074] Step 3: Start the driving motor 9 to lower the telescopic end of the telescopic rod 10, and drive the medicine storage part 4 to descend into the liquid storage part 3, and ensure that the polygonatum sibiricum in the medicine storage part 4 should be completely immersed in the liquid medicine in the liquid storage part 3. Then, stop the first lifting mechanism;

[0075] Step 4: Turn on the heater to keep the temperature of the liquid medicine in the liquid storage part 3 at an appropriate temperature. At the same time, the polygonatum sibiricum should remain immersed in the liquid medicine. This is the soaking stage;

[0076] Step 5: After soaking is completed, start the driving motor 9 again to drive the medicine storage part 4 to rise by the telescopic rod 10 to a set height above the liquid storage part 3 and stop. Then adjust the heater to increase the heating temperature to keep the temperature in the cabinet body 1 above the liquid storage part 3 at the medicine steaming temperature. This is the medicine steaming stage;

[0077] Step 6: After the medicine steaming is completed, turn off the heater to keep the medicine in the cabinet body 1 in this moistening state. At this time, the temperature in the cabinet body 1 gradually decreases, which is the moistening stage;

[0078] Step 7: After the moistening is completed, start the driving motor 9 again to drive the medicine storage part 4 to rise by the telescopic rod 10 until it stops at the drying part 2. Then turn on the dryer until the humidity in the cabinet body 1 reaches the set humidity. This is the drying stage.

[0079] Step 8: After drying is completed, turn off the dryer;

[0080] Step 9: Repeat steps 3 to 8. After repeating steps 3 to 8 for the eighth time, start the driving motor 9 to drive the medicine storage part 4 to descend to the second opening by the telescopic rod 10. Then open the cabinet door and take out the medicine storage part 4 and the prepared nine-processed polygonatum sibiricum in it.

[0081] Further, in this embodiment, except that the soaking needs to be completed in the liquid storage part 3, the remaining three processes of steaming, stewing, and drying can all be completed at the same height in the space of the cabinet body 1 above the liquid storage part 3, thereby reducing the energy consumption required for the lifting of the medicine storage part 4 and achieving the purpose of saving energy. However, completing the three processes of steaming, stewing, and drying in the same space will result in a problem of low drying efficiency. Therefore, as Figure 3 shown, in order to increase the gas flow rate in the cabinet body 1 and improve the drying efficiency of the medicine, a condenser 11 is provided inside or outside the cabinet body 1. The installation method of the condenser 11 includes: 1. Internal condenser 11: The condenser 11 is fixedly installed on the inner wall of the cabinet body 1, with the air inlet of the condenser 11 arranged between the drying part 2 and the liquid storage part 3, and an air suction fan for sucking air into it is arranged at the air inlet of the condenser 11. The upper end of the condenser 11 is provided with an exhaust port, and the exhaust port is located above the air inlet and communicates with the space for drying the medicine; the lower end of the condenser 11 is provided with a liquid discharge port, and the liquid discharge port is located below the air inlet and communicates with the liquid storage part 3.

[0082] 2. External condenser 11: An exhaust pipe is provided on the inner wall of the cabinet body 1 between the drying part 2 and the liquid storage part 3, and the exhaust pipe passes through the cabinet body 1 and is connected to the externally installed condenser 11. The exhaust pipe is connected to the air inlet of the condenser 11 through an air suction fan for sucking air outside the cabinet body 1. The upper end of the condenser 11 is provided with an exhaust port, and the exhaust port is arranged above its air inlet and is connected to the drying part 2 through an air delivery pipe passing through the cabinet body 1 (the best position for the installation of the air delivery pipe is close to the top of the cabinet body 1). The lower end of the condenser 11 is provided with a liquid discharge port, and the liquid discharge port is arranged below its air inlet and is connected to the liquid storage part 3 through a liquid delivery pipe passing through the cabinet body 1.

[0083] Of course, there are many ways to set the condenser 11. As long as it can achieve the purpose of increasing the gas flow rate in the cabinet body 1 and improving the drying efficiency of the medicine, any condenser, condensation structure, or condensation device can be applied to this embodiment.

[0084] In this embodiment, the installation method of the condenser 11 adopted is the external condenser 11, and its air inlet communicates with the cabinet body 1 corresponding to the space between the drying part 2 and the liquid storage part 3. To accelerate the gas flow rate, an air suction fan for sucking air outside the cabinet body 1 is arranged at the air inlet. The exhaust port of the condenser 11 communicates with the drying part 2, and the liquid discharge port communicates with the liquid storage part 3. The air suction fan extracts the high-humidity gas in the cabinet body 1, and the high-humidity gas is sent into the condenser 11 through the air inlet of the condenser 11, and is converted into condensed liquid and dry gas, and enters the drying part 2 and the liquid storage part 3 through the exhaust port and the liquid discharge port respectively, thereby realizing liquid circulation (i.e., medicine juice recovery) and gas circulation (i.e., accelerating the gas flow rate).

[0085] In this embodiment, the gas-liquid circulation mode is as follows:

[0086] (1) Gas circulation mode: The gas with high humidity is drawn from the cabinet 1 (corresponding to between the drying section 2 and the liquid storage section 3) into the condenser 11. The dried gas after being condensed by the condenser 11 is then discharged from the condenser 11 back to the cabinet 1 (corresponding to the drying section 2), thus realizing the air flow circulation. During the gas circulation, the exhaust fan plays a role in accelerating the gas circulation speed, thereby accelerating the gas flow rate inside the cabinet 1.

[0087] (2) Liquid circulation mode: The liquid medicine (originally stored in the liquid storage section 3) evaporated from the gas with high humidity is drawn into the condenser 11 along with the gas from the cabinet 1. The liquid after being condensed by the condenser 11 is then discharged from the condenser 11 and returned to the cabinet (corresponding to the liquid storage section 3), thus realizing the liquid circulation. The liquid contains the liquid medicine components described in this embodiment. Therefore, the process of liquid circulation is also the process of liquid medicine recovery.

[0088] In this embodiment, the dryer provided in the drying section 2 is an air dryer. With the exhaust fan provided, it further improves the air flow speed and drying effect, thereby more effectively improving the drying efficiency.

[0089] In this embodiment, the liquid discharge port of the condenser 11 is arranged in the liquid storage section 3, which is more conducive to the recovery of the medicinal juice. Of course, to prevent the medicinal juice from splashing during the reflux process, a drainage pipe for guiding the reflux of the medicinal juice can also be added at the liquid discharge port, so as to ensure the complete recovery of the medicinal juice.

[0090] In this embodiment, the condenser 11 is a spiral tube heat exchanger. Its purpose is to quickly condense the steam generated during the steaming and simmering stages, thereby further accelerating the air flow speed inside the cabinet 1 and then accelerating the drying process. It can be seen that as long as the condensing device capable of condensing the steam is applicable to this embodiment.

[0091] Regarding the selection of the condensing liquid used in the condenser 11:

[0092] In this embodiment, in addition to using conventional condensate in the condenser 11 (the conventional condensate needs to be discharged outside the cabinet 1 through the condensate pipe passing through the cabinet 1), the medicinal liquid (i.e., auxiliary material) used for soaking the medicine in this embodiment can also be used to replace the conventional condensate. Then, the outlet of the condensate pipe of the condenser 11 is connected to the liquid storage part 3, which can not only ensure the condensation effect of the condenser 11, but also synchronously preheat the medicinal liquid, thereby further reducing the energy consumption required for heating the medicinal liquid. In addition, by using the medicinal liquid to replace the conventional condensate, the medicinal liquid in the liquid storage part 3 can be supplemented, which can effectively avoid affecting the efficacy of the nine-processed polygonatum sibiricum prepared due to insufficient medicinal liquid during the nine-steaming and nine-sunning process of polygonatum sibiricum preparation. Therefore, in this embodiment, the condenser 11 selects the medicinal liquid for soaking the medicine as the condensate to realize the supplement and preheating of the medicinal liquid, and can also reduce the space occupation of the liquid storage part 3 in the cabinet 1 to a certain extent, so as to leave more space in the cabinet 1 for steaming, stewing and drying the medicine, thereby obtaining a better preparation effect and improving the quality of the nine-processed polygonatum sibiricum prepared.

[0093] In this optimization scheme, the use of the condenser is increased. Therefore, in the usage method, only the usage method of the condenser needs to be added in steps seven and eight. The specific modification content is as follows:

[0094] The modified step seven: After the moistening is completed, start the first lifting mechanism again to raise the medicine storage part 4 to the drying part 2, stop the first lifting mechanism, and then turn on the condenser and the dryer until the humidity in the cabinet 1 reaches the set humidity. At this time, it is the drying stage;

[0095] The modified step eight: After the drying is completed, turn off the dryer and the condenser;

[0096] Further, as Figure 2 shown, to ensure that the medicine storage part 4 can stay at the set position, a limiting device 5 is provided on the inner wall of the cabinet 1. The limiting device 5 can be set to multiple according to the height where it needs to stay. If only one limiting device 5 is set, it is preferably set on the inner wall of the cabinet 1 corresponding to the drying part 2 to limit the medicine storage part 4 to stay in the space for drying, that is, the setting height of the limiting device 5 in the cabinet 1 should not be lower than the height of the liquid storage part 3. The limiting device 5 can be set according to the height where it needs to stay.

[0097] In this embodiment, only one limiting device 5 is provided on the inner wall of the cabinet 1 between the liquid storage part 3 and the drying part 2, that is, steaming, stewing and drying the medicine are all completed at the same height. The limiting device 5 used is a limiting structure with a plug and a jack in cooperation. In the prior art, there are also limiting devices such as a snap structure, etc., which can all achieve the purpose of making the medicine storage part 4 stay at the set height. Therefore, as long as the limiting structure or limiting device that can achieve the above purpose can be applied to the embodiment.

[0098] On the basis of this embodiment, electrically controlled functional components can also be set for each functional component, such as an electric air dryer, an electric heater, a cabinet door with electrically controlled opening and closing, an electric pressure controller, etc. By setting a main control computer, an intelligent terminal, an intelligent controller, and a router, the above-mentioned electrically controlled components can be remotely controlled to realize the automation and remote operation of the above processes, further reducing human participation, improving the efficiency of polygonatum preparation. At the same time, it is also easier to control the quality of the prepared nine-processed polygonatum.

[0099] Working principle of this embodiment:

[0100] By adjusting the height of the medicine storage part 4 in the cabinet body 1, the medicine is cycled in turn according to the set four processes of soaking, steaming, stewing, and drying, so as to realize the preparation of nine-processed polygonatum. At the same time, the pressure, temperature, humidity, and liquid level in the set space are controlled by the pressure controller, temperature sensor, humidity sensor, pressure sensor, and liquid level sensor arranged in the cabinet body 1, so as to effectively control each process, and further ensure the quality of the prepared nine-processed polygonatum. Therefore, the utility model has the advantages of simple and efficient working principle, simple structure, convenient operation, low manufacturing cost, and lower working energy consumption.

[0101] In this embodiment, the pressure controller, temperature sensor, humidity sensor, pressure sensor, liquid level sensor, etc. used are all set conventionally and belong to the prior art, so they will not be elaborated here.

[0102] The above is only a preferred embodiment of the present invention, and does not impose any form of limitation on the present invention. Any simple modification or equivalent change made to the above embodiments according to the technical essence of the present invention falls within the protection scope of the present invention.
