Technical Field

[0001] This utility model belongs to the field of traditional Chinese medicine decoction equipment, specifically, it relates to a concentrated decoction machine. Background Technology

[0002] Currently, traditional decoction machines have relatively limited functions, typically only capable of decocting. After decoction, additional equipment and procedures are required to concentrate the liquid, which is cumbersome, inefficient, and prone to contamination and loss during liquid transfer. This not only increases the workload of medical staff but also prolongs the time patients spend obtaining concentrated medicine, failing to adequately meet the demands of modern healthcare for efficiency and convenience.

[0003] Therefore, this application is hereby submitted. Summary of the Invention

[0004] In order to solve at least some of the above-mentioned problems, the purpose of this application is to provide a concentrated decoction machine that can improve decoction efficiency.

[0005] To solve the above-mentioned technical problems, the basic concept of the technical solution adopted in this application is as follows: A concentrated decoction machine includes a blower and a decoction pot and a concentration pot for decocting the medicinal liquid. The decoction pot and the concentration pot are independently heated by a heating system. The decoction pot and the concentration pot are connected or separated by a liquid exchange pipeline. The blower is connected to the decoction pot and the concentration pot through dual air supply pipes, which are used to pressurize and supply gas to the two pots respectively. Driven by the pressure difference, the medicinal liquid is transferred bidirectionally between the decoction pot and the concentration pot through the liquid exchange pipeline.

[0006] In some embodiments, the dual-supply pipe includes a first supply pipe connecting the decoction pot and the blower, and a second supply pipe connecting the concentration pot and the blower.

[0008] In some embodiments, a fluid exchange flow meter is provided on the fluid exchange pipeline.

[0009] In some embodiments, the heating system includes a first heater and a second heater that are independently controlled, the first heater being integrated into the decoction pot and the second heater being integrated into the concentration pot, and the rated power of the second heater being higher than that of the first heater.

[0010] Furthermore, the heating system also includes a temperature sensor connected to the first heater and the second heater.

[0011] In some embodiments, a water collection tank and a condenser are also included. The decoction pot is connected to the condenser through a first exhaust pipe and the concentration pot is connected to the condenser through a second exhaust pipe. A first exhaust valve and a second exhaust valve are respectively provided on the first exhaust pipe and the second exhaust pipe. The water collection tank is connected to a waste liquid pipe through a vacuum drain valve.

[0012] Furthermore, the decoction pot is equipped with a pressing mechanism, which is driven by a geared motor.

The following embodiments are used to illustrate this application, but are not intended to limit the scope of this application.

Therefore, they should not be construed as limitations on this application.

[0023] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium.

[0024] To improve the decoction efficiency when using a concentrated decoction machine, please refer to... Figures 1-2This application provides a concentrated decoction machine, including a blower 1 and a decoction pot 2 and a concentration pot 3 for decocting the medicine. The decoction pot 2 and the concentration pot 3 are independently heated by a heating system. The decoction pot 2 and the concentration pot 3 are connected or disconnected by a liquid exchange pipeline 5. The blower 1 is connected to the decoction pot 2 and the concentration pot 3 respectively through a dual air supply pipe 4, which is used to pressurize and supply gas to the two pots respectively. Driven by the air pressure difference, the medicine is transferred bidirectionally between the decoction pot 2 and the concentration pot 3 through the liquid exchange pipeline 5.

[0025] Furthermore, the decoction pot 2 and the concentration pot 3 are each equipped with an independent heating system (such as an electric heating device), which can control the temperature separately to achieve the functions of decoction and concentration. The bottoms of the two pots are connected by a liquid exchange pipeline 5, and a valve is installed in the pipeline to control the connection or disconnection state.

[0026] Blower 1 is connected to the top of decoction pot 2 and concentration pot 3 respectively through dual air supply pipes 4. Blower 1 can pressurize and supply air to decoction pot 2 or concentration pot 3 individually, or turn off at the same time.

[0027] The decoction machine of this application integrates the decoction pot 2 and the concentration pot 3 into the same device, forming a compact and efficient integrated decoction and concentration machine, which is different from the traditional separate decoction and concentration equipment.

[0028] The workflow during use includes the decoction stage, the initial transfer stage of the medicinal liquid, the concentration stage, and the reverse transfer stage of the medicinal liquid.

[0029] During the decoction stage, close the liquid exchange pipeline 5, add medicinal materials and water to the decoction pot 2, start its heating system for decoction, and keep the concentration pot 3 empty or preheated at a low temperature.

[0030] During the initial transfer of the medicinal liquid, i.e., after the decoction stage is completed, the liquid exchange pipeline 5 is opened, and the blower 1 is started to pressurize and supply air to the decoction pot 2. The air pressure inside the decoction pot 2 increases, and the medicinal liquid flows into the concentration pot 3 through the liquid exchange pipeline 5 under the drive of the air pressure difference. Integrating the decoction and concentration functions into one device reduces intermediate transfer steps, greatly improves work efficiency, and saves time and labor costs. Medical staff only need to operate one device to complete the entire decoction and concentration work. The transfer of the medicinal liquid through the blower 1 reduces the manual transfer process, lowers the risk of contamination and loss of the medicinal liquid, and ensures the purity and efficacy of the medicinal liquid.

[0031] During the concentration stage, the liquid exchange pipeline 5 is closed, and the heating system of the concentration pot 3 is started to concentrate the medicinal liquid at high temperature, while the decoction pot 2 stops heating. Of course, during the concentration stage, the decoction pot 2 can also decoct the medicinal materials. In this case, the heating system heats the decoction pot 2 and the concentration pot 3 independently, and no transfer of medicinal liquid occurs between the two pots, thus achieving isolated decoction and achieving isolated operation of the decoction and concentration processes for different prescriptions.

[0032] During the reverse transfer stage of the decoction, the concentrated decoction is returned to the decoction pot 2 (e.g., for secondary decoction). The blower 1 is activated to pressurize the concentration pot 3, increasing the pressure inside. Driven by the pressure difference, the decoction flows back to the decoction pot 2 via the liquid exchange pipe 5. Addressing the drawback of traditional decoction machines where the secondary decoction (i.e., the decoction in the concentration pot 3) cannot be co-decocted with the decoction in the decoction pot 2, this equipment utilizes a unique blower power transmission design to allow the secondary decoction pot to replace the secondary decoction vessel, enabling the co-decocting of multiple decoctions. This co-decocting method optimizes the mixing and reaction of the decoction components during the decoction process, helping to improve the dissolution rate and interaction effects of active ingredients, thus enhancing the quality of traditional Chinese medicine decoction.

[0033] This application solves the problem of difficult liquid transfer between the concentration pot 3 and the decoction pot 2 in the prior art by using the combination of dual gas supply and independent heating system and gas pressure difference to achieve bidirectional transfer of medicine liquid. It simplifies the operation process and improves the decoction efficiency.

[0034] In some embodiments, the decoction pot is made of high-temperature and corrosion-resistant stainless steel and has a heating system at the bottom to ensure even heating during the decoction process. The top of the decoction pot has an openable feeding port for adding medicinal materials and water, and the feeding port is equipped with a sealing device to prevent steam leakage during the decoction process.

[0035] The concentrator 3 consists of a graduated glass container and a stainless steel pot body with a heating system. The concentrator 3 is connected to the decoction pot 2 through a liquid exchange pipe 5. The concentrator 3 adopts the principle of blowing air to quickly remove the heat in the pot by blowing air, thereby increasing the concentration of the medicine and reducing the amount of medicine.

[0036] In some implementations, see Figure 1 The dual-supply pipe 4 includes a first supply pipe 41 connecting the decoction pot 2 and the blower 1, and a second supply pipe 42 connecting the concentration pot 3 and the blower 1. The first supply pipe 41 is equipped with a first air valve 43, and the second supply pipe 42 is equipped with a second air valve 44.

[0037] The first air supply pipe 41 connects the blower 1 to the top of the decoction pot 2, and the second air supply pipe 42 connects the blower 1 to the top of the concentration pot 3. By controlling the opening and closing states of the first air valve 43 and the second air valve 44, air can be supplied to the decoction pot 2 or the concentration pot 3 separately, or the air supply can be turned off at the same time.

[0038] Specifically, in the initial transfer stage of the medicinal liquid, after the decoction is completed, the valve of the liquid exchange pipeline 5 is opened, the first air valve 43 on the first air supply pipeline 41 is opened, the second air valve 44 on the second air supply pipeline 42 is closed, the blower 1 is started to pressurize and supply air to the decoction pot 2, the air pressure in the decoction pot 2 increases, and the medicinal liquid flows into the concentration pot 3 through the liquid exchange pipeline 5 under the drive of the air pressure difference.

[0039] During the reverse transfer stage of the medicine liquid, the second air valve 44 on the second air supply pipe 42 is opened, the first air valve 43 on the first air supply pipe 41 is closed, the blower 1 is started to pressurize and supply air to the concentration pot 3, the air pressure in the concentration pot 3 increases, and the medicine liquid flows back to the decoction pot 2 through the liquid exchange pipe 5 under the drive of the air pressure difference.

[0040] Through the coordinated control of dual-supply pipes 4 and independent first and second air valves 43 and 44, the pressure difference between the decoction pot 2 and the concentration pot 3 is precisely adjusted to ensure the reliability of bidirectional transfer of the medicine liquid and simplify the operation process.

[0041] In some implementations, see Figure 1 The liquid exchange pipeline 5 is equipped with a first drain valve 51 near the decoction pot 2 and a second drain valve 52 near the concentration pot 3. The liquid exchange pipeline 5 is connected to a medicine discharge pipeline located between the first drain valve 51 and the second drain valve 52 and is equipped with a medicine discharge valve 53.

[0042] The first drain valve 51 and the second drain valve 52 are used to control or isolate the flow of the medicinal liquid between the decoction pot 2 and the concentration pot 3, and the drain pipe, together with the drain valve 53, is used to discharge the medicinal liquid outward.

[0043] Specifically, during the decoction stage, the first drain valve 51, the second drain valve 52, and the medicine drain valve 53 of the liquid exchange pipeline 5 are closed, medicinal materials and water are added to the decoction pot 2, and its heating system is started for decoction.

[0044] During the initial transfer of the medicinal liquid, the first drain valve 51 and the second drain valve 52 of the liquid exchange pipeline 5 are opened, and the blower 1 is started to pressurize and supply air to the decoction pot 2. Driven by the air pressure difference, the medicinal liquid flows into the concentration pot 3 through the liquid exchange pipeline 5.

[0045] During the concentration stage, the first drain valve 51 and the second drain valve 52 are closed, the heating system of the concentration pot 3 is started to concentrate the medicine at high temperature, and the decoction pot 2 stops heating.

[0046] During the reverse transfer stage of the medicinal liquid, the blower 1 is started to pressurize and supply air to the concentration pot 3, and the first drain valve 51 and the second drain valve 52 are opened. The air pressure in the concentration pot 3 increases, and the medicinal liquid flows back to the decoction pot 2 through the liquid exchange pipeline 5.

[0047] During the liquid discharge stage, when only the liquid in the decoction pot 2 needs to be discharged, the second drain valve 52 is closed, and the first drain valve 51 and the discharge valve 53 are opened, and the liquid in the decoction pot 2 is discharged outward through the discharge pipe; when only the liquid in the concentration pot 3 needs to be discharged, the first drain valve 51 is closed, and the second drain valve 52 and the discharge valve 53 are opened, and the liquid in the concentration pot 3 is discharged outward through the discharge pipe; when it is necessary to discharge the liquid in both the decoction pot 2 and the concentration pot 3 at the same time, the first drain valve 51, the second drain valve 52, and the discharge valve 53 are opened simultaneously, and the liquid in both the decoction pot 2 and the concentration pot 3 is discharged outward at the same time.

[0048] This application achieves flexible switching between the transfer of liquid between the two boilers and external discharge by using segmented valve control (first drain valve 51, second drain valve 52) in the liquid exchange pipeline 5 and the independent setting of the drug discharge pipeline. This avoids the problem of residual drug in traditional pipeline designs, while simplifying the operation process and improving the convenience of equipment cleaning. In some implementations, see Figure 1 A liquid exchange flow meter 54 is installed on the liquid exchange pipeline 5. The liquid exchange flow meter 54 is used to monitor the flow rate of the medicine liquid transferred between the decoction pot 2 and the concentration pot 3 in real time.

[0049] During the initial transfer of the medicinal liquid, the flow rate of the medicinal liquid is monitored in real time by the liquid exchange flow meter 54. When all the medicinal liquid is transferred to the concentration pot 3 or the target amount is reached, the first air valve 43 and the drain valve are closed. During the reverse transfer of the medicinal liquid, the reverse flow rate is monitored by the liquid exchange flow meter 54 until the medicinal liquid flows back to the decoction pot 2. When the medicinal liquid is discharged, the liquid exchange flow meter 54 can assist in monitoring the discharge flow rate to ensure that the liquid is completely discharged.

[0050] By adding a liquid exchange flow meter 54, the flow rate of the medicine liquid transfer and discharge can be monitored in real time, so as to achieve precise control of the decoction, concentration and discharge process, avoid the problem of medicine liquid residue or excessive transfer, and further improve the efficiency and quality consistency of decoction.

[0051] In some embodiments, the concentrator 3 includes a graduated glass container. Since the concentrator is a graduated glass container, after all the medicinal liquid from the decoction pot 2 has entered the concentrator, the initial medicinal liquid can be clearly seen in the concentrator 3. After setting the heating time according to the concentration efficiency formula, accurate dispensing of medicine can be achieved.

[0052] In some implementations, see Figure 1 The heating system includes a first heater 6 and a second heater 61, both controlled independently. The first heater 6 is integrated into the decoction pot 2, and the second heater 61 is integrated into the concentration pot 3. The rated power of the second heater 61 is higher than that of the first heater 6. The first heater 6 and the second heater 61 are controlled independently and do not interfere with each other. The rated power of the second heater 61 is higher than that of the first heater 6 to meet the higher heating requirements of the concentration stage.

[0053] During the decoction stage, the first heater 6 is activated to heat the decoction pot 2 separately, and the temperature is controlled for decoction. The second heater 61 of the concentration pot 3 is turned off or maintained at a low temperature for preheating.

[0054] During the concentration stage, the second heater 61 is activated to heat the concentration pot 3 separately, using its higher rated power to quickly increase the temperature and accelerate the concentration of the medicinal liquid, while the first heater 6 of the decoction pot 2 is turned off.

[0055] This embodiment achieves precise temperature control during the decocting and concentration stages through the differentiated design of an independently controlled first heater 6 (dedicated to decocting) and a second heater 61 (dedicated to high-power concentration), avoiding conflicts in heating requirements between the two stages. Furthermore, the higher rated power of the second heater 61 significantly improves concentration efficiency and shortens the processing cycle, while the independent control system ensures operational flexibility and optimized energy consumption.

[0056] In some embodiments, the heating system further includes a temperature sensor 62 connected to the first heater 6 and the second heater 61.

[0057] Furthermore, the first heater 6 and the second heater 61 are respectively connected to independent temperature sensors 62 for real-time monitoring of the temperature of the medicinal liquid in the decoction pot 2 and the concentration pot 3.

[0058] During the decoction stage, the temperature inside the decoction pot 2 is monitored in real time by the temperature sensor 62 connected to the first heater 6, and the heating power is adjusted according to the preset decoction temperature to maintain constant temperature decoction.

[0059] During the concentration stage, the temperature inside the concentration pot 3 is monitored in real time by the temperature sensor 62 connected to the second heater 61, and the heating power is adjusted according to the preset concentration temperature (higher than the decoction temperature) to accelerate the evaporation of the medicinal liquid.

[0060] By equipping the first heater 6 and the second heater 61 with temperature sensors 62 respectively, precise closed-loop temperature control is achieved during the decoction and concentration stages. The temperature sensors 62 provide real-time feedback of the temperature data inside the pots, dynamically adjusting the heating power to avoid efficacy loss or over-concentration caused by temperature fluctuations. At the same time, it ensures the stability and reliability of independent temperature control for the two pots, further improving the quality and efficiency of decoction.

[0061] In some embodiments, the concentrated decoction machine also includes a water collection tank 7 and a condenser 71 connected together. The decoction pot is connected to the condenser 71 through a first exhaust pipe 21 and a second exhaust pipe 31. A first exhaust valve 22 and a second exhaust valve 32 are respectively provided on the first exhaust pipe 21 and the second exhaust pipe 31. The water collection tank 7 is connected to a waste liquid pipe 73 through a vacuum drain valve 72.

[0062] The first exhaust pipe 21 and the second exhaust pipe 31 are used to guide the steam generated during the decoction or concentration process into the condenser 71 for cooling and liquefaction. The outlet of the condenser 71 is connected to the water collection tank 7 to collect the condensed liquid. The bottom of the water collection tank 7 is connected to the waste liquid pipe 73 through the vacuum drain valve 72 to discharge the waste liquid. The first exhaust valve 22 and the second exhaust valve 32 are used to control the steam discharge path of the decoction pot 2 or the concentration pot 3. When the condensate in the water collection tank 7 needs to be cleaned, the vacuum drain valve 72 is opened and the waste liquid is discharged through the waste liquid pipe 73.

[0063] By adding a condenser 71, a water collection tank 7, and separate controlled first and second exhaust pipes 21 and 31, the steam generated during the decoction and concentration stages is directionally condensed and recovered, reducing the impact of steam emissions on the operating environment. Simultaneously, waste liquid is centrally treated through waste liquid pipe 73, improving the equipment's environmental friendliness and safety. Separate first and second exhaust valves 22 and 32 ensure independent and controllable steam emission paths for the two boilers, preventing pressure interference during the liquid transfer process.

[0064] In some embodiments, the decoction pot 2 is equipped with a pressing mechanism, which is driven by a geared motor. The rotational motion of the geared motor is converted into a linear thrust in the vertical direction through a linked screw and nut transmission pair to press the dregs in the decoction pot 2 up and down.

[0065] In some embodiments, the geared motor is fixed to the top outer side of the decoction pot 2, and the output shaft extends into the pot through a sealed bearing; the lead screw and nut drive pair is vertically installed and coaxially linked with the output shaft of the geared motor, and the nut is fixed to the extrusion plate; the extrusion plate is horizontally set inside the decoction pot 2, and the surface is provided with a filter screen or through holes to allow the medicinal liquid to pass through while blocking the medicinal residue; when the geared motor drives the lead screw to rotate, the nut drives the extrusion plate to move up and down in the vertical direction, applying linear extrusion force to the decoction residue.

[0066] The decoction pot 2 integrates an extrusion mechanism that mechanically extrudes the dregs after decoction, significantly improving the extraction rate of the medicinal liquid and reducing the residue of effective ingredients. The vertical linear movement of the extrusion plate and the filtration design ensure efficient separation of the medicinal liquid and dregs, while avoiding the risk of contamination of the medicinal liquid by traditional stirring or centrifugal structures. It also seamlessly integrates with existing heating, liquid exchange, and blower systems to improve the overall efficiency and quality of decoction.

[0067] In some implementations, see Figure 1 The decoction pot 2 is connected to a first inlet pipe 23, and the concentration pot 3 is connected to a second inlet pipe 33. The first inlet pipe 23 and the second inlet pipe 33 are respectively equipped with a first inlet valve 24, a second inlet valve 34 and an inlet flow meter 8.

[0068] The first inlet pipe 23 is connected to the top or side wall of the decoction pot 2 and is used to inject liquid (such as water or solvent) into the decoction pot 2. The pipe is equipped with a first inlet valve 24 and an inlet flow meter 8 in sequence to control the liquid inlet and monitor the flow rate. The second inlet pipe 33 is connected to the top or side wall of the concentration pot 3 and is used to inject liquid into the concentration pot 3. The pipe is equipped with a second inlet valve 34 and an inlet flow meter 8 in sequence, and has the same function as the first inlet pipe 23.

[0069] By separating the first inlet pipe 23 and the second inlet pipe 33, and equipping them with independent inlet valves and flow meters, precise and independent liquid addition control is achieved between the decoction pot 2 and the concentration pot 3. The inlet flow meter 8 ensures consistent liquid addition.

[0070] In some implementations, see Figure 1 and Figure 2 It also includes a controller 9, which is electrically connected to the heating system and the liquid exchange flow meter 54. The controller 9 is a microprocessor or PLC module, which is electrically connected to and controls the opening and closing of the first heater 6 and the second heater 61 and their power output, and at the same time receives real-time flow data from the liquid exchange flow meter 54.

[0071] Specifically, the controller 9 monitors the operating status of the first heater 6 in real time and dynamically adjusts the heating power according to the preset temperature; the liquid exchange flow meter 54 transmits the flow data to the controller 9 in real time. When the flow reaches the preset value, the controller 9 automatically shuts off the blower 1 and the valve of the liquid exchange pipeline 5, terminating the transfer; if the concentrate needs to be replenished, the controller 9 controls the secondary transfer operation based on the flow data fed back by the liquid exchange flow meter 54; during reverse transfer, the controller 9 simultaneously controls the blower 1 to pressurize and monitors the liquid exchange flow meter 54 to ensure that the concentrate is returned as needed. The integrated controller 9 enables precise temperature control of the heating system and data linkage with the liquid exchange flow meter 54. The controller 9 automatically terminates the transfer of medicinal liquid based on flow feedback, avoiding over- or under-treatment caused by human error; at the same time, by dynamically adjusting the heating power, it optimizes energy consumption and ensures the stability of decoction and concentration temperatures, significantly improving decoction efficiency and product consistency.
