Description

Technical Field

[0001] The utility model relates to the technical field of traditional Chinese medicine processing, in particular to a concentrating device for producing traditional Chinese medicine formula granules. Background Art

[0002] Concentration of traditional Chinese medicine granules is a key step in the pharmaceutical manufacturing process. It involves physically removing some of the water from the extract to increase the concentration of the active ingredients and facilitate subsequent drying and granulation. Modern Chinese medicine concentration technologies primarily include evaporation, membrane concentration, freeze concentration, and adsorption separation.

[0003] During concentration, the density of the concentrate must be constantly monitored to achieve the density specified by the process. Different varieties require different densities, and each variety has different paste yields and material viscosities. This density cannot be estimated during production, requiring constant measurement, which can be cumbersome. Therefore, we propose a concentrating device for the production of traditional Chinese medicine granules. Utility Model Content

[0004] The purpose of the utility model is to provide a concentration device for the production of traditional Chinese medicine formula granules, which has the advantages of constantly monitoring the density of traditional Chinese medicine and calculating the actual density based on the collected data, thereby solving the problem that different varieties of traditional Chinese medicine require different concentration densities, which leads to troublesome measurement operations.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solution: a concentrating device for producing Chinese medicine formula granules, comprising an inner tank body and an outer tank body, wherein the top of the inner tank body is connected to an air outlet pipe, the bottom is connected to a liquid outlet pipe, and the side is provided with a feed pipe;

[0006] The outer tank body is provided with an air inlet, and the air outlet pipe of the inner tank body is connected to a vacuum pump, and the vacuum pump is used to reduce the pressure of the inner tank body during the concentration process. The inner tank body is installed with a vacuum sensor and a density meter, and the vacuum sensor is used to monitor the pressure change inside the inner tank body, and the density meter is used to detect the density of the liquid medicine;

[0007] A controller is installed outside the outer tank body, and the controller is used to calculate the actual density of the liquid medicine according to the data of the vacuum sensor and the density meter.

[0008] Preferably, a condenser is connected to the gas outlet pipe of the inner tank body, and the condenser is used to liquefy the evaporated gas.

[0009] Preferably, a liquid level gauge is provided in the inner tank body, and the liquid level gauge is used to detect the volume of the medicinal liquid.

[0010] Preferably, a stirring motor is installed on the outer tank body, an output shaft of the stirring motor is connected to a stirring rod in the inner tank body, and a stirring frame is provided on the stirring rod.

[0011] Preferably, a circulation pump and a circulation pipe are provided on the outer tank body, and the circulation pump is used to pump the gas in the outer tank body from one end to the other end of the circulation pipe. One end of the circulation pipe is connected to the bottom of the outer tank body, and the other end is connected to the top of the outer tank body.

[0012] Preferably, the circulation pump is connected to a discharge pipe, the discharge pipe is provided with a discharge valve, and the circulation pipe is provided with a circulation valve.

[0013] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0014] The utility model includes a densitometer that measures density based on the principle that the static pressure of a liquid column of a certain height is proportional to the liquid's density. The static pressure value measured by the pressure measuring instrument can be used to calculate the liquid's density. However, since vacuuming is required in both reduced-pressure concentration and freeze-concentration to improve concentration efficiency and reduce concentration costs, and the density after vacuuming decreases compared to the actual density, a controller calculates the actual density of the concentrated Chinese medicine based on data from the densitometer and vacuum sensor. This solves the problem of different Chinese medicine varieties requiring different concentration densities, which can lead to cumbersome measurement operations. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0019] like Figure 1and 2 As shown, a concentrating device for producing Chinese medicine formula granules includes an inner tank body 2 and an outer tank body 1. The top of the inner tank body 2 is connected to an air outlet pipe 3 for discharging evaporated water vapor, and the bottom is connected to a liquid outlet pipe 4 for discharging concentrated Chinese medicine liquid. A feed pipe 5 is provided on the side for adding the liquid medicine to be concentrated.

[0020] The outer tank body 1 is provided with an air inlet 6 for introducing cold or hot air. The cold air can be liquid nitrogen or other cryogenic gases, while the hot air can be heated air or other gases. Cold air is used for freeze concentration, while hot air is used for reduced pressure concentration. Both methods can be selected based on the needs. Both methods require a vacuum pump 7 to evacuate the liquid. Therefore, a vacuum pump 7 is connected to the outlet pipe 3 of the inner tank body 2. The vacuum pump 7 is used to reduce the pressure of the inner tank body 2 during the concentration process. A vacuum sensor 8 and a density meter 9 are installed in the inner tank body 2. The vacuum sensor 8 is used to monitor the pressure changes inside the inner tank body 2, and the density meter 9 is used to detect the density of the liquid medicine.

[0021] A controller 10 is mounted on the exterior of the outer tank 1. This controller is used to calculate the actual density of the liquid based on data from the vacuum sensor 8 and the density meter 9. Utilizing a PLC control system, the controller 10 primarily calculates the change in density due to reduced pressure, thereby determining the actual density of the liquid. Data on the effects of varying pressures on density can also be input into the controller 10 in advance.

[0022] Density meter 9 measures density based on the principle that the static pressure of a liquid column of a certain height is proportional to the liquid's density. The static pressure value measured by the pressure measuring instrument can be used to calculate the liquid's density. However, since vacuuming is required in both reduced-pressure concentration and freeze-concentration to improve concentration efficiency and reduce costs, and the density after vacuuming decreases compared to the actual value, controller 10 calculates the actual density of the concentrated traditional Chinese medicine based on the data from density meter 9 and vacuum sensor 8.

[0023] The outlet pipe 3 of the inner tank 2 is connected to a condenser 11, which is used to liquefy evaporated gases. When using reduced pressure concentration, reducing the boiling point of the liquid medicine by lowering the pressure makes it easier for water to evaporate. This is suitable for concentrating liquid medicines containing heat-sensitive ingredients to minimize their destruction. Evaporated water vapor from the liquid medicine passes through the condenser 11 and is collected before being discharged, thus preventing excessive water from being drawn into the vacuum pump 7.

[0024] A liquid level gauge 12 is provided in the inner tank 2, which can detect the volume of the medicinal liquid and help determine the density of the Chinese medicinal liquid.

[0025] The outer tank body 1 is provided with a stirring motor 13, the output shaft of which is connected to a stirring rod 14 in the inner tank body 2, and a stirring frame 15 is provided on the stirring rod 14. By providing the stirring motor 13, the heating or cooling of the liquid medicine can be facilitated, the temperature of the liquid medicine can be uniformed, agglomeration can be avoided, and the liquid discharge efficiency can be improved.

[0026] The outer tank 1 is provided with a circulation pump 16 and a circulation pipe 17. The circulation pump 16 is used to pump the gas within the outer tank 1 from one end to the other end of the circulation pipe 17. One end of the circulation pipe 17 is connected to the bottom of the outer tank 1, and the other end is connected to the top of the outer tank 1. When using evaporative vacuum concentration, hot air is injected into the outer tank 1 through the air inlet 6 to heat and evaporate the water in the liquid. When using freeze concentration, the water is removed by freezing, and the water in the ice crystals is removed by decompression. Whether hot or cold air is introduced, the gas can be circulated through the circulation pump 16 and circulation pipe 17 to achieve a uniform temperature.

[0027] Circulation pump 16 is connected to a discharge pipe 18, which is equipped with a discharge valve 19. Circulation pipe 17 is also equipped with a circulation valve 20. To circulate gas, discharge valve 19 in discharge pipe 18 is closed, circulation valve 20 in circulation pipe 17 is opened, and circulation pump 16 drives the gas to circulate. When concentration is complete, discharge valve 19 in discharge pipe 18 is opened, circulation valve 20 in circulation pipe 17 is closed, and circulation pump 16 drives the gas to be discharged.

[0028] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
