[0002] In the process of modern traditional Chinese medicine production, the production process of traditional Chinese medicine preparations includes extraction, concentration, purification, drying and other links. The concentration link is a key step in determining the quality and production efficiency of traditional Chinese medicine preparations. A large amount of steam is required in the traditional Chinese medicine extraction process, and the steam consumption in concentration accounts for a relatively large proportion, resulting in a high energy consumption cost. The existing multi-tank concentration systems of concentration devices rely on multiple pumps to achieve the flow of liquid medicine between tanks. Each concentration tank needs to be equipped with an independent pump, which leads to an increase in cost investment. Moreover, when multiple pumps operate simultaneously, the power consumption is superimposed, resulting in an increase in energy consumption cost. Summary of the Invention

Specific embodiments

[0019] In order to more clearly understand the above objects, features and advantages of the present application, the present application will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the embodiments of the present application and the features in the embodiments can be combined with each other.

[0020] Many specific details are set forth in the following description in order to fully understand the present application. However, the present application may be implemented in other ways different from those described herein. Therefore, the protection scope of the present application is not limited by the specific embodiments disclosed below.

[0021] The following refers to Figures 1 to 14 Describe an energy-saving traditional Chinese medicine concentration device according to some embodiments of the present application.

[0022] As Figure 1 Shown in Figure 4 As shown, the energy-saving traditional Chinese medicine concentration device according to some embodiments of the present application includes a double-effect concentration mechanism 100, a pressure accumulation mechanism 500 and a liquid infusion mechanism 600. Among them, the double-effect concentration mechanism 100 includes a first-effect concentration tank group and a second-effect concentration tank group. The first-effect concentration tank group and the second-effect concentration tank group are connected through a concentration pipeline 200. Each concentration tank group includes a heating tank and a separation tank; the first-effect concentration tank group completes the first-stage circulating concentration of the liquid medicine, and the second-effect concentration tank group completes the second-stage circulating concentration of the liquid medicine. The second-effect concentration tank group is connected to the first-effect concentration tank group, and the liquid medicine completes the third-stage circulating concentration between the second-effect concentration tank group and the first-effect concentration tank group; two pressure accumulation mechanisms 500 are provided in each separation tank, and each pressure accumulation mechanism 500 converts the steam pressure output by each heating tank into mechanical energy; two liquid infusion mechanisms 600 are provided in each separation tank, and each liquid infusion mechanism 600 is connected to the corresponding pressure accumulation mechanism 500, and each liquid infusion mechanism 600 drives the separated liquid medicine to flow back by using the mechanical energy of the corresponding pressure accumulation mechanism 500.

[0023] In this embodiment, in the first-effect concentration tank group, the heating tank heats the liquid medicine, and the generated liquid medicine vapor enters the separation tank through the concentration pipeline 200. Liquid medicine separation is achieved in the separation tank. The separated liquid traditional Chinese medicine flows back to the heating tank to complete the primary circulation of the liquid medicine. The heating tank of the second-effect concentration tank group receives the high-temperature vapor from the separation tank of the first-effect concentration tank group as a heat source to heat the liquid medicine. The generated liquid medicine vapor after heating enters the separation tank of the second-effect concentration tank group for gas-liquid separation. The separated liquid traditional Chinese medicine flows back to the second-effect heating tank to complete the secondary circulation concentration of the liquid medicine. Since the second-effect concentration tank group is connected to the first-effect concentration tank group, the liquid medicine further circulates between the second-effect concentration tank group and the first-effect concentration tank group to achieve a tertiary circulation concentration, enabling the liquid medicine to be more fully concentrated. The pressure accumulation mechanism 500 is arranged in the separation tank. Utilizing the vapor pressure output by the heating tank, the pressure accumulation mechanism 500 converts the vapor pressure into mechanical energy to drive the liquid infusion mechanism 600 to assist the liquid medicine to flow back to the heating tank through the concentration pipeline 200 for liquid medicine circulation. By utilizing the free energy of the vapor pressure to achieve liquid medicine transportation, additional power equipment is reduced, and the energy consumption and cost of the equipment are lowered.

[0024] In some possible embodiments, as Figures 2 - 6 shown, the double-effect concentration mechanism 100 includes: a support frame 110, and the support frame 110 includes a plurality of accommodation cavities; a control box 120 fixedly connected to the support frame 110; a first-effect heating tank 130 arranged on the accommodation cavity; a first-effect separation tank 140 arranged on the accommodation cavity, and the first-effect separation tank 140 is arranged on the side of the first-effect heating tank 130 away from the control box 120; a second-effect heating tank 150 arranged on the accommodation cavity, and the second-effect heating tank 150 is arranged on the side of the first-effect separation tank 140 away from the first-effect heating tank 130; a second-effect separation tank 160 arranged on the accommodation cavity, and the second-effect separation tank 160 is arranged on the side of the second-effect heating tank 150 away from the second-effect heating tank 150; the first-effect heating tank 130 and the second-effect heating tank 150 include a vapor channel and a liquid medicine channel.

[0025] In this embodiment, the control box 120, the first-effect heating tank 130, the first-effect separation tank 140, the second-effect heating tank 150, and the second-effect separation tank 160 are sequentially installed on the support frame 110. The liquid medicine is first input into the first-effect heating tank 130, and the steam is input into the steam channel of the first-effect heating tank 130, and the liquid medicine is input into the corresponding liquid medicine channel. The flow of the steam and the liquid medicine does not interfere with each other. The liquid medicine is initially heated and evaporated in the first-effect heating tank 130. A large amount of liquid medicine steam will be generated when the liquid medicine is affected by the high-temperature steam. These steams enter the first-effect separation tank 140. In the first-effect separation tank 140, the liquid medicine steam is condensed to realize the separation of the liquid medicine and the gas. The separated liquid medicine flows back into the first-effect heating tank 130 for secondary heating and concentration. At the same time, the gas containing a certain amount of heat separated in the first-effect separation tank 140 enters the second-effect heating tank 150 to heat the liquid medicine in the second-effect heating tank 150, so that the liquid medicine in the second-effect heating tank 150 generates liquid medicine steam. These steams enter the second-effect separation tank 160, and the gas and the liquid medicine are separated again in the second-effect separation tank 160. The separated liquid medicine flows back into the second-effect heating tank 150 for secondary concentration, and the liquid medicine will continuously circulate in the first-effect heating tank 130 and the second-effect heating tank 150 to realize the multiple-cycle concentration of the liquid medicine until the required concentration degree is reached.

[0026] In some possible embodiments, as Figure 4 shown, the double-effect concentration mechanism 100 further includes: a feed port 141 provided at the bottom of the first-effect separation tank 140; a discharge port 151 provided at the bottom of the second-effect heating tank 150.

[0027] In this embodiment, the feed port 141 provides an input channel for the liquid medicine, and the bottom-feed method enables the liquid medicine to directly enter the first-effect separation tank 140, reducing the residue of the liquid medicine in the pipeline or at the top of the tank; the discharge port 151 provides an output channel for the liquid medicine, and the discharge port 151 is provided at the bottom of the second-effect heating tank 150. The gravity effect can completely discharge the concentrated liquid medicine in the tank. During the concentration process, the viscosity of the liquid medicine gradually increases, reducing the residue of the liquid medicine and reducing the waste of the liquid medicine, thereby improving the production efficiency of traditional Chinese medicine.

[0028] In some possible embodiments, as Figure 4As shown, the concentration pipeline 200 includes: a first mixing pipe 210 disposed between the first-effect heating tank 130 and the first-effect separation tank 140; a first recovery pipe 220 disposed between the first-effect separation tank 140 and the second-effect heating tank 150; a second mixing pipe 230 disposed between the second-effect heating tank 150 and the second-effect separation tank 160; a first circulation pipe 240 disposed on a side away from the first mixing pipe 210 between the first-effect heating tank 130 and the first-effect separation tank 140; a second circulation pipe 250 disposed on a side away from the second mixing pipe 230 between the second-effect heating tank 150 and the second-effect separation tank 160; an infusion pipe 260 disposed between the first-effect heating tank 130 and the second-effect heating tank 150; and an infusion pump 270 disposed on the infusion pipe 260.

[0029] In this embodiment, after the liquid medicine enters the first-effect separation tank 140 through the feed port 141, it enters the liquid medicine channel of the first-effect heating tank 130 via the first circulation pipe 240. And high-temperature steam is input into the steam channel of the first-effect heating tank 130. The liquid medicine contacts the high-temperature steam to generate liquid medicine steam. The liquid medicine steam generated by heating and evaporation is transported from the first-effect heating tank 130 to the first-effect separation tank 140 via the first mixing pipe 210. The function of the first mixing pipe 210 is to guide the liquid medicine steam generated in the first-effect heating tank 130 into the first-effect separation tank 140 to ensure that the steam can smoothly enter the separation process. In the first-effect separation tank 140, the liquid medicine steam is condensed, so the liquid medicine is separated from the gas. The separated liquid medicine flows back to the first-effect heating tank 130 through the first circulation pipe 240 for secondary heating and concentration. The first circulation pipe 240 forms a circulation path for the liquid medicine, enabling the separated liquid medicine to return to the first-effect heating tank 130 again to achieve the cyclic concentration of the liquid medicine. At the same time, the gas separated in the first-effect separation tank 140 containing a certain amount of heat is transported to the second-effect heating tank 150 via the first recovery pipe 220. The first recovery pipe 220 plays the role of transporting the heat transfer medium, transporting the gas with a certain amount of heat separated in the first-effect separation tank 140 to the second-effect heating tank 150 to achieve the preliminary utilization of heat. After the gas containing heat enters the second-effect heating tank 150, it heats the liquid medicine in the second-effect heating tank 150, contacts the liquid medicine in the second-effect heating tank 150 to generate liquid medicine steam, and the generated liquid medicine steam is transported from the second-effect heating tank 150 to the second-effect separation tank 160 via the second mixing pipe 230. The function of the second mixing pipe 230 is to be responsible for transporting the liquid medicine steam generated in the second-effect heating tank 150 to the second-effect separation tank 160 for separation. In the second-effect separation tank 160, the gas and the liquid medicine are separated again. The separated liquid medicine flows back into the second-effect heating tank 150 through the second circulation pipe 250 for secondary concentration. The second circulation pipe 250 constructs a liquid medicine circulation path between the second-effect heating tank 150 and the second-effect separation tank 160 to ensure that the liquid medicine can be fully concentrated in the second-effect heating tank 150. At the same time, the infusion pipe 260 is arranged between the first-effect heating tank 130 and the second-effect heating tank 150, and the infusion pump 270 is arranged on the infusion pipe 260 to realize the cyclic flow of the liquid medicine between the first-effect heating tank 130 and the second-effect heating tank 150. Promote the liquid medicine circulation between the two heating tanks, enable the liquid medicine to fully contact the heat source, and achieve the effect of multiple cyclic concentration.

[0030] In this design, through the reasonable setting of the pipes of the concentration pipeline 200, such as the first mixing pipe 210, the second mixing pipe 230, the first circulation pipe 240 and the second circulation pipe 250, a clear circulation path for the liquid medicine and the steam is formed. The liquid medicine can flow quickly and orderly between multiple heating tanks and separation tanks, enabling the liquid medicine to fully contact the heat source, greatly improving the heating and evaporation efficiency, thereby shortening the concentration time of the liquid medicine and improving the overall production efficiency.

[0031] In some possible embodiments, such as Figures 6 - 9 shown, the heat recovery mechanism 300 includes: an evaporator 310 disposed on one side of the accommodation cavity of the support frame 110 close to the second-effect separation tank 160; a compressor 320 disposed on one side of the accommodation cavity of the support frame 110 close to the first-effect heating tank 130; a subcooler 330 disposed on one side of the accommodation cavity of the support frame 110 away from the first-effect heating tank 130; a throttle valve 340 disposed between the evaporator 310 and the subcooler 330; and a liquid collection tank 350 disposed on one side of the accommodation cavity of the support frame 110 away from the second-effect separation tank 160.

[0032] In this embodiment, the gas separated by the second-effect separation tank 160 contains a certain amount of heat. These gases with heat are transported to the evaporator 310, where the refrigerant exchanges heat with the gas. The refrigerant absorbs the heat in the gas, thereby realizing the preliminary recovery of the heat in the gas separated by the second-effect separation tank 160. At this time, the refrigerant changes from a liquid state to a medium-temperature and low-pressure gaseous state and becomes a medium carrying heat. The medium-temperature and low-pressure refrigerant vapor is then transported to the compressor 320, where the compressor 320 compresses it, significantly increasing the pressure and temperature of the refrigerant vapor and turning it into a high-temperature and high-pressure gaseous refrigerant. The high-temperature and high-pressure gaseous refrigerant output by the compressor 320 is input into the first-effect heating tank 130. In the first-effect heating tank 130, the high-temperature and high-pressure refrigerant vapor exchanges heat with the liquid medicine, transferring the heat it carries to the liquid medicine, increasing the temperature of the liquid medicine, and thereby promoting the evaporation and concentration process of the liquid medicine. After the heat exchange, the refrigerant vapor is converted into a gas-liquid mixture state and is output from the first-effect heating tank 130 to the subcooler 330. In the subcooler 330, the refrigerant further releases heat, and its state gradually changes from a gas-liquid mixture state to a liquid state. The liquid refrigerant is discharged from the subcooler 330 and undergoes a throttling and pressure-reducing process through the throttle valve 340. The throttle valve 340 reduces the pressure and temperature of the refrigerant, turning it into a low-temperature and low-pressure liquid refrigerant, and then enters the evaporator 310 to start a new round of cycle. During the heat recovery process, the vapor gradually cools down and is converted into a liquid, which is collected by the liquid collection tank 350, and these liquids can provide a low-temperature medium for the heat exchange process of the subcooler 330, helping to improve the heat exchange efficiency of the subcooler 330.

[0033] In this design, the heat recovery mechanism 300 can utilize the heat in the gas separated by the second-effect separation tank 160, transfer the heat in the gas to the refrigerant through the evaporator 310, then improve the heat quality through the compression of the compressor 320, and finally input the high-temperature and high-pressure refrigerant into the first-effect heating tank 130 to realize the heat supplement for the heating and concentration process of the liquid medicine, reintroducing the heat that might otherwise be wasted into the system for utilization, greatly improving the energy utilization efficiency and reducing the overall energy consumption of the system.

[0034] In some possible embodiments, such as Figures 6 - 9 As shown, the heat recovery pipeline 400 includes: a second recovery pipe 410 disposed between the second-effect separation tank 160 and the evaporator 310; a heat transfer pipe 420 disposed between the first-effect heating tank 130 and the compressor 320; a liquid return pipe 430 disposed between the first-effect heating tank 130 and the subcooler 330; and a waste liquid pipe 440 disposed between the second-effect heating tank 150 and the liquid collection tank 350.

[0035] In this embodiment, the second recovery pipe 410 is used to transport the gas separated by the second-effect separation tank 160 to the evaporator 310; the heat transfer pipe 420 is used to transport the high-temperature and high-pressure gaseous refrigerant generated by the compressor 320 into the first-effect heating tank 130; the liquid return pipe 430 is used to transport the refrigerant vapor that has completed heat exchange in the first-effect heating tank 130 into the subcooler 330; the waste liquid pipe 440 is used to transport the liquid generated by the heat release and condensation of the vapor in the second-effect heating tank 150 to the liquid collection tank 350; the heat recovery pipeline 400 ensures the smooth flow of the medium during the heat recovery process.

[0036] In some possible embodiments, such as Figures 10 - 13 As shown, each pressure accumulation mechanism 500 includes: a clamping seat 510 disposed inside the second-effect separation tank 160, and the clamping seat 510 is connected to the first mixing pipe 210; a piston cylinder 520 disposed on the clamping seat 510, and the piston cylinder 520 has a through hole; a first piston 530 disposed inside the piston cylinder 520; a control member 540 connected to the first piston 530, and the control member 540 includes a first boss; a first spring 550 disposed on the first piston 530, and the first spring 550 is disposed between the piston cylinder 520 and the control key 540; a blocking ring 560 disposed outside the through hole of the piston cylinder 520; a push rod 570 fixedly connected to the blocking ring 560, and the push rod 570 includes a second boss, and the second boss cooperates with the first boss of the control member 540.

[0037] In this embodiment, in the initial state, the first spring 550 is in its natural state, and the blocking ring 560 blocks the outside of the through hole of the piston cylinder 520. When the liquid medicine in the first-stage heating tank 130 is heated to generate liquid medicine vapor, the vapor enters the piston cylinder 520 connected to the clamping seat 510 through the first mixing pipe 210. As the vapor continuously enters, the first piston 530 is subjected to a thrust force, causing the first spring 550 to be compressed. The first piston 530 moves horizontally, and the control member 540 also moves accordingly. At the same time, the position of the first convex platform changes. When the first piston 530 moves to a certain position, the first convex platform of the control member 540 contacts the second convex platform of the push rod 570 and pushes the push rod 570. Thus, the push rod 570 moves with the control member 540. Since the push rod 570 is fixedly connected to the blocking ring 560, the blocking ring 560 moves accordingly, leaving the outside of the through hole of the piston cylinder 520, opening the through hole. Thus, the vapor is input into the first-stage separation tank 140 through the through hole. As the vapor is continuously discharged, the vapor pressure in the piston cylinder 520 gradually decreases. When the vapor pressure is not sufficient to overcome the elastic force of the first spring 550, the first spring 550 resumes its elasticity, causing the first piston 530 to move towards the clamping seat 510. The reset of the first piston 530 drives the control member to move, and the first convex platform separates from the second convex platform of the push rod 570. The push rod 570 drives the blocking ring 560 back to the outside of the through hole of the piston cylinder 520, and the pressure accumulation mechanism 500 returns to the initial state, waiting for the action of the vapor pressure next time.

[0038] In this design, by converting the vapor pressure into mechanical energy to control the liquid medicine delivery, the effective conversion and utilization of energy are achieved, energy waste is avoided, and the energy utilization rate of the entire system is improved.

[0039] It should be noted that the mechanical structures and working principles of the pressure accumulation mechanisms 500 inside the second-stage separation tank 160 and the first-stage separation tank 140 are the same, and will not be elaborated here.

[0040] In some possible embodiments, as Figure 12 shown, each pressure accumulation mechanism 500 further includes: two limit blocks 521, respectively arranged on both sides of the piston cylinder 520; the clamping seat 510 has a limit slot for accommodating the limit blocks 521.

[0041] In this embodiment, the piston cylinder 520 is installed on the limit slot of the clamping seat 510 through the limit blocks 521. The limit slot allows the limit blocks 521 to move, and the limit blocks 521 are detachably installed on the limit slot. Then, the piston cylinder 520 is a detachable design, and it is possible to choose whether to use the pressure accumulation mechanism 500 according to actual usage requirements, improving the convenience of the equipment.

[0042] In some possible embodiments, as Figure 13 、 Figure 14As shown in the figure, the liquid infusion mechanism 600 includes: a squeezing frame 610, fixedly connected to the control member 540, and the squeezing frame 610 is in a ramp shape; a fixed seat 620, arranged on one side of the second-effect separation tank 160 close to the clamping seat 510; a fixed frame 630, detachably connected to the fixed seat 620, and the fixed frame 630 includes a circular support block; a lifting rod 640, arranged on the circular support block of the fixed frame 630; a convex ring 641, fixed on the side of the lifting rod 640 close to the circular support block; a contact wheel group 650, arranged at one end of the lifting rod 640 close to the squeezing frame 610, and the contact wheel group 650 is in contact with the squeezing frame 610; a second spring 660, arranged on the lifting rod 640, and the second spring 660 is distributed between the circular support block and the convex ring 641; a return port, arranged at the bottom end of the second-effect separation tank 160; a second piston 670, arranged at one end of the lifting rod 640 away from the contact wheel group 650, and the return port has a cavity, and the cavity provides movement for the second piston 670.

[0043] In this embodiment, in the initial state, the second spring 660 is in a natural state, and the second piston 670 is located at the top end of the cavity in the return port. When the control member 540 of the pressure accumulation mechanism 500 moves, the squeezing frame 610 connected to the control member 540 moves accordingly. Since the squeezing frame 610 is in a ramp shape, during the movement, a downward pressure is applied to the contact wheel group 650, pushing the lifting rod 640 and the second piston 670 to move downward. The convex ring 641 on the lifting rod 640 moves downward accordingly, and the second spring 660 is stretched. Then, the second piston 670 generates a downward force to assist the separated liquid medicine to be discharged through the return port and be transported back to the heating tank via the concentration pipeline 200, realizing the circulation of the liquid medicine. As the vapor is continuously discharged, the control member 540 drives the squeezing frame 610 to reset, and the second spring 660 restores its elasticity, and then the second piston 670 resets accordingly.

[0044] In this design, the liquid infusion mechanism 600 does not need to additionally set up power equipment to transport the liquid medicine, makes full use of the free energy in the system, and effectively reduces the energy consumption and operation cost of the equipment.

[0045] In some possible embodiments, as Figure 14 shown, the liquid infusion mechanism 600 further includes: a first one-way valve 680, arranged on the second piston 670; a second one-way valve 690, arranged on the return port.

[0046] In this embodiment, the main functions of the first one-way valve 680 and the second one-way valve 690 are to prevent the liquid medicine in the heating tank from flowing back into the return port under the vapor pressure, reduce system failures and abnormal conditions caused by the backflow or leakage of the liquid medicine, and improve the stability and reliability of the entire equipment system.

[0047] When the energy-saving traditional Chinese medicine concentration equipment is operating, first, the liquid medicine enters the first-effect separation tank 140 through the feed port 141 and enters the liquid medicine channel of the first-effect heating tank 130 via the first circulation pipe 240. At the same time, the compressor 320 inputs high-temperature and high-pressure refrigerant into the steam channel of the first-effect heating tank 130 through the heat transfer pipe 420. The liquid medicine contacts the high-temperature steam to generate liquid medicine steam. The liquid medicine steam generated by heating and evaporation is transported from the first-effect heating tank 130 to the first-effect separation tank 140 through the first mixing pipe 210. The steam enters the piston cylinder 520 connected to the clamping seat 510 through the first mixing pipe 210, pushing the first piston 530 to move, and the control part 540 also moves accordingly. When the first piston 530 moves to a certain position, the control part 540 pushes the push rod 570, causing the blocking ring 560 to leave the outside of the through hole of the piston cylinder 520, and the steam is input into the first-effect separation tank 140 through the through hole. In the first-effect separation tank 140, the liquid medicine and gas in the liquid medicine steam are separated. The extrusion frame 610 connected to the control part 540 moves accordingly, applying a downward pressure on the contact wheel group 650, pushing the lifting rod 640 and the second piston 670 to move downward. The second spring 660 is stretched, and the second piston 670 generates a downward force to assist the separated liquid medicine to be discharged through the reflux port and transported back to the first-effect heating tank 130 via the first circulation pipe 240, forming a cycle of the liquid medicine between the first-effect heating tank 130 and the first-effect separation tank 140. The gas containing a certain amount of heat separated in the first-effect separation tank 140 is transported to the second-effect heating tank 150 through the first recovery pipe 220 to heat the liquid medicine in the second-effect heating tank 150, causing the liquid medicine in the second-effect heating tank 150 to generate liquid medicine steam. The generated liquid medicine steam is transported from the second-effect heating tank 150 to the second-effect separation tank 160 through the second mixing pipe 230. In the second-effect separation tank 160, the gas and liquid medicine are separated again. The separated liquid medicine flows back to the second-effect heating tank 150 through the second circulation pipe 250 for secondary concentration, forming a cycle of the liquid medicine between the second-effect heating tank 150 and the second-effect separation tank 160. At the same time, the liquid delivery pipe 260 and the liquid delivery pump 270 realize the circulating flow of the liquid medicine between the first-effect heating tank 130 and the second-effect heating tank 150, promoting the multiple-cycle concentration of the liquid medicine. The gas with heat separated by the second-effect separation tank 160 is transported to the evaporator 310. In the evaporator 310, the refrigerant exchanges heat with the gas. The refrigerant absorbs the heat in the gas. The low-temperature and low-pressure refrigerant vapor is then transported to the compressor 320 for compression treatment, transformed into high-temperature and high-pressure gaseous refrigerant, and input into the first-effect heating tank 130 to exchange heat with the liquid medicine, transferring the heat to the liquid medicine and promoting the evaporation and concentration process of the liquid medicine. After the heat exchange, the refrigerant vapor is converted into a gas-liquid mixture state, transported to the subcooler 330 to be converted into a liquid state, and further releases heat. Thus, after passing through the throttle valve 340 for throttling and pressure reduction treatment, it is transformed into low-temperature and low-pressure liquid refrigerant, and then enters the evaporator 310 to start a new round of cycle.The liquid collecting tank 350 is used to collect the liquid generated during the exothermic condensation of the refrigerant and provide a low-temperature medium for the heat exchange process of the subcooler 330. When the liquid medicine reaches the required concentration, it is discharged through the discharge port 151 provided at the bottom of the second-effect heating tank 150.,
