Description

Technical Field

[0001] This invention relates to the field of traditional Chinese medicine decoction equipment, specifically to a fully enclosed vacuum centrifugal decoction equipment for decoction, filling, and packaging. Background Technology

[0002] Traditional Chinese medicine decoctions are one of the most widely used dosage forms in clinical practice. Their preparation process follows core theories such as decocting first and then adding ingredients, starting with high heat and then simmering, prolonged decoction, wrapping and decocting separately, and melting. It aims to retain volatile active ingredients while promoting the full dissolution of insoluble components. The quality of the decoction directly affects clinical efficacy. Traditional decoction methods primarily use clay pots, earthenware pots, and sandpots. While these provide even heating and stable properties, limitations in technology mean that volatile components easily escape with the steam, large amounts of water are added, resulting in high moisture content in the dregs, low utilization of active ingredients, and difficulty in consistently controlling the quality of the decoction.

[0003] With technological advancements, traditional manual decoction of Chinese medicine has gradually been upgraded to electrically heated, sealed decoction machines, evolving towards automation and intelligence. However, existing decoction equipment still has many shortcomings. For example, the decoction and filling processes cannot achieve a completely sealed vacuum, the space in containers and pipes is too large, resulting in significant loss of volatile and easily oxidized components; the water addition is still too high, the dregs have a high moisture content, and the insoluble components are not completely dissolved; the equipment often simply imitates traditional processes and fails to truly follow the core theories of Chinese medicine decoction, resulting in low utilization of effective components.

[0004] Currently, hospital decoction centers and smart pharmacies generally suffer from problems such as fixed decoction volumes, excessive use of medicinal slices, and serious waste of herbs. Their actual therapeutic effects are even inferior to those of traditional, precise decoctions prepared in clay pots. The industry generally lacks rapid and objective methods for evaluating the quality of decoctions. The Chinese Pharmacopoeia's requirements for decoction yield are too low, and quality control standards are inconsistent and unregulated, severely hindering the modernization and high-quality development of traditional Chinese medicine.

[0005] Meanwhile, both classic prescriptions from various dynasties and the clinical practices of renowned traditional Chinese medicine practitioners in modern times have shown that, through reasonable process improvements, the amount of medicinal materials used can be significantly reduced while ensuring efficacy. The amount of pills and powders used is usually only 1 / 3 to 1 / 10 of that used in decoctions, or even less, thus saving medicinal materials and reducing the burden on patients. However, existing equipment cannot meet the integrated decoction requirements of sealed vacuum, low temperature with minimal loss, efficient dissolution, low moisture content, and full process control. Summary of the Invention

[0006] This invention provides a fully enclosed vacuum centrifugal decoction equipment for decoction filling and packaging, which solves the problems of high loss of volatile components, low dissolution of insoluble components and high moisture content of dregs in existing decoction equipment.

[0007] The present invention provides a fully enclosed vacuum centrifugal decoction equipment for decoction filling and packaging, which adopts the following technical solution: A fully enclosed vacuum centrifugal decoction equipment for decoction, filling, and packaging includes a decoction pot, a filling assembly, a first compensation component, and a second compensation component.

[0008] At least two decoction pots are provided, one of which is used for decocting medicines resistant to high temperature and pressure, and the other is used for decoctions of medicines that require short decoction times, are easily oxidized, and are volatile. Each decoction pot has a drain outlet at its lower end and a drug inlet; the drug is added into the decoction pot through the inlet and then the inlet is sealed. The filling assembly includes a filling tank, and the drain outlets of both decoction pots are connected to the filling tank via liquid guide pipes. The filling tank is used for dispensing and filling the medicine solution into smaller packages. A first compensation component is used to transport volatile substances generated during the decoction process to the filling tank. The first compensation component can also expel volatile substances from the filling tank during the dispensing and filling process. A second compensation component is used to reduce the oxygen content inside the decoction pots and the filling tank.

[0009] Furthermore, the frying pan is equipped with a centrifugal component, which is used to stir the medicine to absorb water evenly after the medicine is put into the frying pan. The centrifugal component can also promote the effective components of the medicine to quickly separate from the dregs after the medicine is decocted in the frying pan.

[0010] Furthermore, the centrifugal assembly includes a centrifugal cylinder and a driving component. The centrifugal cylinder is coaxially rotatably disposed inside the frying pan. The centrifugal cylinder is hollowed out and is shaped like a frustum. The diameter of the upper end of the centrifugal cylinder is smaller than the diameter of the lower end. The driving component is used to drive the centrifugal cylinder to rotate around its own axis inside the frying pan. The driving component can change the rotation speed of the centrifugal cylinder.

[0011] Furthermore, the driving component includes a drive motor, the power output shaft of which is coaxially and fixedly connected to the centrifuge drum.

[0012] Furthermore, the driving component includes an electromagnetic drive disk, and the bottom of the centrifuge tube is made of neodymium iron boron magnet. When the electromagnetic drive disk is energized, the centrifuge tube can rotate under the action of electromagnetic force.

[0013] Furthermore, the centrifuge tube is provided with a detachable mesh cover at its upper end.

[0014] Furthermore, the first compensation component includes an escape pipe that connects the upper end of the frying pan to the upper end of the filling can, and the escape pipe is equipped with a valve to obstruct gas flow.

[0015] Furthermore, the first compensation component also includes a compression airbag and a vacuum pump. The compression airbag is disposed inside the filling tank and can deform inside the filling tank. The vacuum pump is disposed outside the filling tank and is used to extract gas from inside the compression airbag. The vacuum pump can also deliver gas into the compression airbag.

[0016] Furthermore, the second compensation component includes a vacuum pump for extracting gas from the inside of the frying pan and the filling container; the vacuum pump is used to extract gas from the inside of the frying pan before the medicine is decocted.

[0017] Furthermore, pressure gauges are installed on the frying pan and the filling can, and a thermometer is also installed on the frying pan.

[0018] The beneficial effects of this invention are as follows: This invention provides a fully enclosed vacuum centrifugal decoction equipment for decoction, filling, and packaging, comprising a decoction pot, a filling assembly, a first compensation component, and a second compensation component. Two decoction pots are provided; one pot is used for decoction of drugs resistant to high temperatures and pressures, while the other pot is used for decoction of drugs with short decoction times, easy oxidation, and easy volatility. This classification of drugs by properties prevents under- or over-decoction. The decoction liquid from the two pots, after processing the drugs with different properties, is transported through a liquid guide pipe to the filling tank of the filling assembly. The filling tank can then package the decoction liquid into individual containers. Volatile substances are generated during the decoction process. The first compensation component can transport these volatile substances to the filling tank. It can also squeeze the volatile substances that have entered the filling tank out during the packaging process. In addition, during the decoction process, oxygen in the air can oxidize the medicine, thus affecting its efficacy. At this time, the second compensation component reduces the oxygen content inside the decoction pot and the filling tank, ensuring that the medicine after packaging can be less likely to be oxidized. This solves the problem of high loss of volatile components and low dissolution of poorly soluble components in existing decoction equipment.

[0019] Furthermore, by installing a centrifugal component inside the decoction pot, the centrifugal component can stir the medicine added to the pot before the medicine is decocted, ensuring that the medicine can fully absorb water in the early stage of decoction; after the medicine is decocted, in order to reduce the amount of medicine in the dregs, the centrifugal component can centrifuge the dregs, ensuring that the effective components in the medicine can be extracted, while reducing the water content in the dregs.

[0026] like Figure 1 As shown in the figure, the present invention provides a fully enclosed vacuum centrifugal decoction equipment for decoction, filling and packaging, which includes a decoction pot 1, a filling assembly, a first compensation component and a second compensation component.

[0027] The frying pot 1 has an upward-facing decoction chamber, which serves as the inlet for adding the herbs. The herbs to be decocted are added into the chamber through this inlet, as is the water required for decoction. A sealing lid is installed at the top of the frying pot 1 to seal the inlet after the water and herbs have been added. A heating wire is installed inside the frying pot 1 to heat the contents to a preset temperature, which can be customized by the operator according to actual needs.

[0028] At least two decocting pans 1 are provided. One decocting pan 1 is used for decocting medicines that are resistant to high temperature and pressure, and the other decocting pan 1 is used for medicines that require short decoction times, are easily oxidized, and are volatile. The medicines that are resistant to high temperature and pressure are minerals and some animal and plant medicinal slices that do not easily absorb water. The medicines that require short decoction times, are easily oxidized, and are volatile include ginseng, deer antler, and cordyceps. A drain port is provided at the lower end of the decocting pan 1, and a drain valve is provided at the drain port. The drain valve can control the conduction state of the drain port. When the medicine has not been decocted, the drain valve is in the state of sealing the drain port.

[0029] The filling assembly includes a filling tank 11. The drain ports of the two decoction pots 1 are connected to the filling tank 11 through the liquid guide pipe 9. When the decoction is completed, the drain valve is opened, and the liquid in the decoction pots 1 can flow into the filling tank 11 through the liquid guide pipe 9. The filling tank 11 is used to fill the liquid into packets. Furthermore, the filling tank 11 can adjust the amount of filling according to the dosage taken by the patient each time, so as to facilitate the patient's drinking.

[0030] When the medicine is decocted in the decoction pot 1, the medicine will produce volatile substances when heated. These volatile substances can escape and reduce the efficacy of the decoction. The first compensation component can transport the volatile substances generated during the decoction process into the filling tank 11, reducing their escape. Furthermore, after the volatile substances enter the filling tank 11, the first compensation component can also squeeze them out of the filling tank 11 during the packaging process, ensuring that the volatile substances enter each package of medicine, thereby reducing the loss of effective substances.

[0031] When the medicine is decocted in the decoction pot 1, and when the medicine is packaged and filled, the medicine will undergo an oxidation reaction when it comes into contact with oxygen. The oxidized medicine will reduce its efficacy. At this time, the second compensation component reduces the oxygen content inside the decoction pot 1 and the filling tank 11, thereby reducing the probability of the medicine being oxidized.

[0032] This invention discloses a fully enclosed vacuum centrifugal decoction equipment for decoction, filling, and packaging. Two decoction pots (1) are provided. One pot is used for decocting drugs resistant to high temperatures and pressures, while the other pot is used for decocting drugs that require short decoction times, are easily oxidized, or are highly volatile. This classification of drugs by properties prevents under- or over-decoction. The decoction liquid from both pots is then transported via a liquid guide pipe (9) to a filling tank (11) in the filling assembly, where the liquid is packaged and filled. Volatile substances are generated during the decoction process in the pots. The first compensation component can transport volatile substances into the filling tank 11. The first compensation component can also squeeze the volatile substances that have entered the filling tank 11 out of the filling tank 11 during the sub-packaging process. In addition, during the decoction process in the decoction pot 1, the oxygen in the air will oxidize the medicine, thereby affecting the efficacy of the medicine. At this time, the second compensation component reduces the oxygen content inside the decoction pot 1 and the filling tank 11, ensuring that the medicine after sub-packaging can reduce the probability of oxidation, thereby solving the problem of high loss of volatile components and low dissolution of poorly soluble components in the existing decoction equipment during the decoction process.

[0033] In one embodiment, the decoction pot 1 is equipped with a centrifugal component. This component is used to stir the medicine evenly after it is added to the decoction pot 1 to ensure it absorbs water. Specifically, initially, the centrifugal component stirs the medicine to ensure it is evenly exposed to water, then soaks it. The centrifugal component is then used again to stir the medicine, changing its position in contact with the water to ensure it absorbs water fully and evenly. Furthermore, after the decoction is complete, the centrifugal component rapidly centrifuges the medicine to remove residual water, ensuring the complete extraction of active ingredients and reducing the water content in the dregs.

[0034] In one embodiment, the centrifugation assembly includes a centrifuge cylinder 2 and a drive component 3. The centrifuge cylinder 2 is coaxially rotatably disposed inside the frying pan 1. The centrifuge cylinder 2 is hollowed out and is shaped like a frustum. The diameter of the upper end of the centrifuge cylinder 2 is smaller than the diameter of the lower end. When decocting the medicine, the medicine is put into the centrifuge cylinder 2. By defining the outline of the centrifuge cylinder 2, the probability of the medicine being thrown outside the centrifuge cylinder 2 is reduced during the rotation of the centrifuge cylinder 2.

[0035] Furthermore, the driving component 3 is used to drive the centrifuge cylinder 2 to rotate around its own axis inside the decoction pot 1. The driving component 3 can change the rotation speed of the centrifuge cylinder 2. Specifically, in the initial stage when the medicine is added into the centrifuge cylinder 2, the driving component 3 first drives the centrifuge cylinder 2 to rotate at a speed of 600 rpm for half a minute to promote full contact between the medicine and water; then the medicine is soaked in water for half an hour, and the driving component 3 drives the centrifuge cylinder 2 to rotate at a speed of 600 rpm for half a minute again to ensure that the medicine can fully absorb water; at this time, the medicine is decocted. After the decoction is completed, the driving component 3 drives the centrifuge cylinder 2 to rotate at a speed of 600 rpm for half a minute again, which can accelerate the release of volatile substances in the decoction; during the discharge of the decoction, the driving component 3 drives the centrifuge cylinder 2 to rotate again, first at 600 rpm for 2-3 minutes, then at 1000 rpm for 2-3 minutes, and then at 1400 rpm for 4-6 minutes, until no more decoction is discharged from the decoction pot 1.

[0036] In one embodiment, the drive unit 3 includes a drive motor, the power output shaft of which is coaxially fixedly connected to the centrifuge tube 2, and the speed at which the drive motor drives the centrifuge tube 2 to rotate can be manually adjusted.

[0037] In one embodiment, the driving component 3 includes an electromagnetic driving disk, and the bottom of the centrifuge cylinder 2 is made of neodymium iron boron magnet. When the electromagnetic driving disk is energized, the centrifuge cylinder 2 can rotate under the action of electromagnetic force. During the rotation of the centrifuge cylinder 2, the centrifuge cylinder 2 is in a suspended state inside the frying pan 1. Compared with the direct drive method of the drive motor, the magnetic levitation rotation method can reduce the probability of the medicine liquid coming into contact with other materials, thereby avoiding interference with the efficacy of the medicine.

[0038] In one embodiment, a removable mesh cover is provided at the upper end of the centrifuge tube 2. By providing a removable mesh cover, the situation of drug escaping to the outside of the centrifuge tube 2 during the rotation of the centrifuge tube 2 is further prevented.

[0039] In one embodiment, the first compensation component includes an escape pipe 4 that connects the upper end of the decocting pan 1 to the upper end of the filling tank 11. The escape pipe 4 is equipped with a valve to impede gas flow. Initially, the valve on the escape pipe 4 is closed. When the decocting pan 1 begins heating to decoct the medicine, the valve on the escape pipe 4 opens, allowing volatile substances generated during heating to enter the filling tank 11 through the escape pipe. After the decoction pan 1 has finished decocting the medicine and begins discharging the medicine from the decocting pan 1, the valve on the escape pipe 4 is sealed.

[0040] In one embodiment, the first compensation component further includes a compression airbag and a vacuum pump 5. The compression airbag is disposed inside the filling tank 11, specifically at the upper part of the filling tank 11, and can deform inside the filling tank 11. The vacuum pump 5 is disposed outside the filling tank 11 and is used to extract gas from inside the compression airbag. The vacuum pump 5 can also deliver gas into the compression airbag.

[0041] To make it easy to understand, when the liquid medicine has completely entered the filling tank 11, the squeezing air bladder is at its smallest state. When the liquid medicine is being packaged and filled, the amount of liquid medicine gradually decreases. At this time, the space above the inside of the filling tank 11 gradually increases. At this time, the air pump 5 gradually supplies air into the squeezing air bladder, causing the squeezing air bladder to gradually expand, thus avoiding the occurrence of negative pressure above the inside of the filling tank 11, and thus preventing the situation where the liquid medicine cannot be completely filled.

[0042] In one embodiment, the second compensation component includes a vacuum pump 6, which is used to extract gas from the inside of the frying pan 1 and the filling tank 11; the vacuum pump 6 is used to extract gas from the inside of the frying pan 1 before the medicine is decocted. Specifically, the vacuum pump 6 can independently extract the gas inside the decocting pot 1 and the filling tank 11. After the medicine is put into the decocting pot 1, both the inside of the decocting pot 1 and the filling tank 11 are in a sealed state. At this time, the gas inside the decocting pot 1 and the filling tank 11 is extracted to reduce the oxygen content inside the decocting pot 1 and the filling tank 11 and to extract the negative pressure inside the decocting pot 1 and the filling tank 11 to the same state. Then the vacuum pump 6 is turned off. During the decoction process, the escaping pipe 4 connects the upper end of the filling tank 11 with the upper end of the decocting pot 1. Volatile substances are continuously generated in the decocting pot 1, which causes the negative pressure inside the decocting pot 1 and the filling tank 11 to gradually decrease, and the volatile substances gradually enter the filling tank 11. After the medicine is decocted, the valve on the escaping pipe 4 is closed. At this time, the medicine liquid gradually enters the filling tank 11 through the liquid guide pipe 9.

[0043] In one embodiment, pressure gauges 7 are provided on both the frying pan 1 and the filling tank 11, and thermometers 8 are also provided on the frying pan 1. By providing pressure gauges 7 and thermometers 8, it is convenient for staff to observe the relevant temperature and pressure during the decoction process, so as to ensure that the effective components in the decoction can be fully extracted into the liquid.

[0044] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
