DETAILED DESCRIPTION

[0029] 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 described embodiments 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 creative work are within the scope of protection of the present invention.

[0030] Unless otherwise specified, the technical means used in the embodiments are conventional means well known to those skilled in the art.

[0031] The invention discloses a preparation method of liver-benefiting tea. The liver-benefiting tea is placed in a medicine tank on a processing device according to its type, and each medicinal material is washed with water. The washing can be done manually or by increasing the water pressure of a water adding pipe. After the sewage after washing is discharged through a liquid discharge pipe, water is added again and added to a filter plate 2 in a tank body 1 of the processing device together with the medicinal materials. The tea is heated and boiled during stirring until 1 / 2 to 2 / 3 of the amount of water added is added. Water is added again and boiled until the water level is located in the middle of the filter plate 2 of the processing device. A stirring mechanism in the processing device squeezes the liver-benefiting tea in the filter plate 2. During the squeezing process, the tea is boiled until the water level is located below the filter plate 2 in the processing device. The boiled medicinal liquid is discharged and concentrated, and finally processed into tea paste or tea preparation. The condensation mechanism on the processing device can condense the volatilized water vapor and the active ingredients contained therein and flow them into the tank body again, thereby avoiding the volatilization or loss of the active ingredients in the medicine to the greatest extent. At the same time, the active ingredients are dissolved to the greatest extent through multiple boilings supplemented with squeezing.

[0032] As one embodiment, the liver-benefiting tea includes 270 parts of green leaf gall, 120 parts of wormwood, 110 parts of astragalus, 110 parts of verbena, 110 parts of ganoderma lucidum, 110 parts of selfheal, 80 parts of southern isatis root, 50 parts of bupleurum, 25 parts of scutellaria, and 15 parts of gentian. It has the effects of clearing away heat and detoxification, promoting blood circulation and dispersing blood stasis, soothing the liver and benefiting the body, and invigorating qi and raising yang. It is used for jaundice, bloating, abdominal distension, pain under the ribs, poor appetite and qi stagnation caused by qi and blood deficiency, damp-heat toxicity, and meridian stasis; acute and chronic liver diseases with the above symptoms. Oral. Take with warm water / boiled water. Adults take 10g at a time, twice a day. Children take half the amount, or follow the doctor's advice.

[0033] In the prior art, there is no disclosed equipment capable of implementing the above-mentioned preparation process. Figure 1-Figure 8 As shown, the present invention also discloses a processing device for preparing the above-mentioned liver-benefiting tea, including a tank body 1, a filter plate 2 is arranged in the tank body 1, and a plurality of filter holes are arranged on the filter plate, a liquid-filling plate 3 is arranged below the filter plate 2, and the liquid-filling plate is arranged at the inner bottom of the tank body, and a support platform 4 is arranged at the center of the liquid-filling plate 3, and the bottom of the support platform has a base, so that its cross section is T-shaped; the filter plate 2 is placed on the support platform 4, and in order to avoid the support platform from blocking the filter holes at the bottom of the filter plate, a plurality of guide grooves 42 are arranged on the table surface of the support platform, and the bottom of the guide groove is inclined, and is inclined from the center of the support platform toward its edge, so that the medicinal liquid flows into the liquid-filling plate through the guide groove. That is, the guide grooves are arranged radially on the support platform. When the medicinal material is squeezed, the support platform plays a supporting role, and assists the fan-shaped blades to complete the squeezing of the medicinal material. As one of the preferred schemes, the outer diameter of the support platform is greater than or equal to the bottom diameter of the filter plate to avoid the bottom edge of the filter plate from being suspended.

[0034] Furthermore, a stirring mechanism is vertically arranged above the filter disc 2 and in the tank body 1, and a flow guide 5 is arranged in the tank body 1 and above the filter disc 2. A condenser pipe 6 is connected to the flow guide 5, and the condenser pipe 6 extends out of the tank body 1 and communicates with the side wall of the tank body 1 in the area surrounded by the filter disc 2 and the flow guide 5. The flow guide 5 is in an arc shape, and when steam condenses in the flow guide, the formed droplets can flow into the bottom of the tank body along its inner arc surface, so as to avoid a large amount of condensed droplets hanging on the inner top of the tank body.

[0035] Furthermore, a water cooling jacket 7 is provided on the condenser tube 6 located outside the tank body 1. The water cooling jacket is an annular sleeve with a hollow interior. The water cooling jacket 7 is connected to a water inlet pipe 8 and a water outlet pipe. Specifically, the water inlet pipe is connected to the top of the water cooling jacket, and the water outlet pipe is connected to the bottom of the water cooling pipe. The water inlet pipe 8 and the water outlet pipe are connected to a water tank 9. A water pump 10 is provided on the water inlet pipe 8. Water is pumped into the water cooling jacket by the water pump and then discharged into the water tank through the water outlet pipe, thereby realizing the circulation of cooling water in the water cooling jacket, so that the steam entering the condenser tube condenses into droplets after passing through the water cooling jacket and flows into the tank body again. One end of the water cooling pipe connected to the side wall of the tank body is tilted downward to prevent droplets from being deposited at the bottom of the condenser tube.

[0036] Furthermore, the liquid-containing pan 3 is in an arc shape and is adapted to the interior of the tank body 1. The edge of the filter pan fits the inner wall of the tank body as closely as possible, and the edge of the liquid-containing pan can be fixed to the inner wall of the tank body according to actual conditions. The liquid-containing pan is fixed to the bottom of the tank body, and the filter pan is arranged close to the liquid-containing pan and supported by a support platform. The deflector 5 is arranged close to the top of the tank body 1 with an opening facing downward, the liquid-containing pan 3 is arranged at the inner bottom of the tank body 1 with an opening facing upward, the filter pan 2 is in an internally hollow truncated cone shape, and the opening of the large diameter end faces upward; the outer diameter of the small diameter end of the filter pan 2 (i.e., the bottom of the filter pan) is less than or equal to the outer diameter of the support platform 4, and the stirring mechanism extends into the filter pan 2.

[0037] Furthermore, in order to discharge the liquid medicine in the liquid-filling tray, a plurality of liquid medicine discharge pipes 11 connected to the bottom of the liquid-filling tray 3 are inserted into the bottom of the tank body 1, and the liquid medicine discharge pipes 11 are arranged around the base 30 of the support platform 4, and a sealing plug 13 is arranged on the liquid medicine discharge pipes 11. It should be noted that: the base of the support platform passes through the liquid-filling tray and is fixed to the inner bottom of the tank body, and the liquid medicine discharge pipes are arranged around the base, so as to discharge the liquid medicine, and at the same time, the stability of the support platform is not affected. The side of the liquid medicine discharge pipe close to the base is adapted to the shape of the side wall of the base.

[0038] Furthermore, a cavity 14 is provided at the bottom of the tank body 1 and on the side wall of the tank body 1 near the liquid filling tray 3, and a heating device is provided in the cavity 14. The heating device is a prior art device, such as a heating wire, a heating rod, etc., which heats the tank body; a switchable sealing door 15 is provided on the side wall of the tank body 1 corresponding to the filter tray 2, which is convenient for taking out the filter tray and pouring out the medicine residue.

[0039] Furthermore, the stirring mechanism includes a stirring shaft 29, one end of which extends out of the top of the tank body 1 and is driven by a motor 16, such as by a chain or gear transmission; a plurality of rotating shafts 17 are horizontally arranged on the bottom circumference of the stirring shaft 29, and fan-shaped blades 18 are sleeved on the rotating shaft 17. There is a certain gap between the fan-shaped blades and the stirring shaft, so that the fan-shaped blades can rotate around the rotating shaft at a certain angle. The rotating shaft 17 is connected along the radial direction of the blades. The rotating shaft 17 is provided with a torsion spring that resists the fan-shaped blades 18. In the initial state, the fan is tilted on the rotating shaft 17, and the angle and direction of rotation are the same. The two sides of each fan-shaped blade 18 are respectively provided with a slot 19 in opposite directions, that is, the slot is arranged along the radial direction of the fan-shaped blade. When the fan-shaped blade 18 rotates, the slot 19 on each fan-shaped blade 18 is buckled with the slot 19 on the fan-shaped blade 18 adjacent to the fan-shaped blade 18, so that all the fan-shaped blades 18 are combined to form a circle, thereby squeezing the medicinal materials in the filter disc. Although the upward movement of the support platform can also close the fan-shaped blades, because the medicinal materials are in the filter disc, when the support platform moves upward with the filter disc, there is a situation where the medicinal materials are sandwiched in the gap between the adjacent fan-shaped blades, which makes the fan-shaped blades unable to close. Therefore, the pressure plate is first driven to close the fan-shaped blades, and then the support platform is driven to move upward.

[0040] Further, the stirring shaft is provided with a sleeve 20, which is arranged in the tank body. A pressure plate 21 is arranged on the circumference of one end of the sleeve 20 close to the fan-shaped blade 18. A sealing ring 22 is arranged between the sleeve 20 and the stirring shaft 29 to prevent the liquid from entering the gap between the sleeve and the stirring shaft. The top of the sleeve 20 passes through the deflector 5 and is sleeved and fixed with a first bearing 23. The outer ring of the first bearing 23 is fixed with an annular plate 24. The top surface of the annular plate 24 extends out of the tank body 1 by setting a plurality of guide pillars 25 and is fixed with a connecting plate 26. The connecting plate 26 is driven to move up and down by a second telescopic member 27. The stirring shaft 29 passes through the connecting plate 26 and is fixed to the tank body 1 by a second bearing 28. The second telescopic member includes but is not limited to an electric telescopic rod, a hydraulic telescopic rod, and a cylinder.

[0041] Furthermore, in order to achieve the squeezing of medicinal materials by the fan-shaped blades, the support platform 4 is separated from the base 30. The base 30 is in the shape of a tube with openings at both ends. A sealing pad 31 is provided at the top thereof and contacts the top surface of the support platform 4. When the medicinal materials are boiled, water is prevented from entering the gap between the base and the output shaft of the first telescopic member. The bottom of the tank body 10 is provided with a first telescopic member 12. The output shaft of the first telescopic member 12 passes through the bottom of the tank body 1 and extends into the base 30, and is fixed at the center of the bottom surface of the support platform 4. The first telescopic member includes but is not limited to an electric telescopic rod, a hydraulic telescopic rod, and a cylinder. When necessary, a sealing sleeve is provided on the side wall of the output shaft or on the inner wall of the base to increase the sealing of the base and avoid leakage. When it is necessary to squeeze the medicinal materials, the first telescopic member is started to move the support platform toward the fan-shaped blades until the medicinal materials in the filter disc are pressed against the fan-shaped blades, thereby completing the squeezing work.

[0042] Furthermore, in order to add medicinal materials into the tank body, an arc groove 34 with a bottom inclined downward toward the tank body 1 is provided on the side wall of the tank body 1, and a plurality of partitions 35 are provided in the arc groove 34 to divide the arc groove 34 into a plurality of medicine grooves. A discharge port 36 communicating with the tank body 1 is provided on the side wall of each medicine groove, and a baffle 37 that can move up and down is provided on the discharge port 36. A drainage pipe 38 is provided at the bottom of the medicine groove, and a valve is provided on the drainage pipe. A filter screen 39 is provided at the bottom of the medicine groove at the pipe mouth of the drainage pipe 38, and a water supply pipe 40 is provided above each medicine groove, and the water supply pipe 40 is connected to a water supply main pipe 41, and the water supply main pipe 41 is connected to a water tank 9, and a pump is provided on the water supply main pipe 41, and a valve is provided on each water supply pipe 40. It should be noted that: a third telescopic member 32 is provided at the top center of the baffle, and the third telescopic member is fixed on the outer wall of the tank body. The third telescopic member includes but is not limited to an electric telescopic rod, a hydraulic telescopic rod, and a cylinder. In order to increase the stability of the baffle when it moves up and down, limit plates 33 are respectively provided on both sides of the medicine groove. The two ends of the baffle are inserted into the gap between the limit plate and the inner wall of the arc groove. When the baffle is raised or lowered, it is raised or lowered along the gap to prevent the baffle from tilting or detaching from the discharge port. The drain pipe is arranged close to the discharge port, that is, as close as possible to the lowest point of the bottom of the arc groove, so as to filter out the sewage used to wash the medicinal materials as much as possible. When it is necessary to add water to the medicine groove, it is only necessary to pump the water to the water adding main pipe through a water pump, and then enter the water adding pipes respectively, and decide which medicine grooves need to be added with water by controlling the valves on the water adding pipes.

[0043] In the present invention, the number and layout of the arc grooves, condensing pipes and water tanks can be set according to actual conditions.

[0044] When using the present invention, the medicinal materials of larger volume can be crushed according to the actual situation, and added to the medicine tank according to the dosage requirements. Then, the water pump is turned on to let water flow into the water tank to flush the medicinal materials, and then the drainage pipe is opened to discharge the sewage; the valve of the drainage pipe is closed, and the water pump is turned on again to add water to the medicine tank. After adding to the appropriate water level, the third telescopic member 32 is started, and the discharge port is opened. Under the action of the water and the inclined surface of the bottom of the medicine tank, the water and the medicinal materials enter the filter plate in the tank body (directly placing the medicinal materials can also make them enter the tank body); the water level in the tank body can be added to the tank body through the medicine tank to the appropriate water level as needed. After the medicinal materials are added as needed, the tank body is heated and boiled. It should be noted that the order and timing of adding the medicinal materials can be operated according to the above process according to the boiling requirements. The medicinal materials are boiled according to the preparation method of the present invention. When boiled to a certain extent, the second telescopic member is started to move the pressing plate downward until the fan-shaped blades are merged. Then, the first telescopic member is activated to move the support table upward until the fan-shaped blades press the medicinal materials. This process can be adjusted according to actual conditions. For example, when the water level is boiled below the support table, the liquid medicine in the medicinal materials is squeezed out. After the extrusion is completed, the pressing plate and the support plate are reset, and the liquid medicine can be concentrated by continuing to boil until it becomes thick and can be discharged through the liquid medicine discharge pipe. Of course, after the boiling of the medicinal materials is completed, the liquid medicine can also be directly discharged and concentrated by another device to make tea paste or tea preparation.

[0045] In the description of the present invention, it should be understood that the terms "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside" and "outside" etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.

[0046] The embodiments described above are only descriptions of the preferred modes of the present invention, and are not intended to limit the scope of the present invention. Without departing from the design spirit of the present invention, various modifications and improvements made to the technical solutions of the present invention by ordinary technicians in this field should all fall within the protection scope determined by the claims of the present invention.
