Description

Technical Field

[0001] The present application relates to the technical field of torch flower root processing, and specifically discloses a device for preparing alcohol precipitation liquid of torch flower root extract. Background Art

[0002] The main ingredient of Torch Flower Root is Malus kunmingensis, an herb used in traditional Chinese medicine to treat a variety of inflammatory and autoimmune diseases. The drug helps relieve symptoms of rheumatoid arthritis and lupus erythematosus through its anti-inflammatory and immunosuppressive effects.

[0003] Torch flower root extract is a product prepared from torch flower roots. Currently, the more common technology for preparing torch flower root extract is the water decoction and alcohol precipitation method. The water decoction and alcohol precipitation method is to cool the clear paste to about 60°C, add 95% ethanol, stir and mix to form an alcohol precipitate, let the alcohol precipitate stand, filter, and recover the ethanol to obtain the extract.

[0004] At present, a stirring tank is usually used for the preparation of alcohol precipitation liquid. First, the clear paste to be alcohol precipitated is passed into the stirring tank, and then ethanol with a volume fraction of 85-95% is continuously passed and stirred. In the production process, the greater the amount of ethanol added, the more effective substances in the clear paste can be extracted and the fewer impurities. However, when a large amount of ethanol is added to the stirring tank, the local ethanol concentration will be too high, and a large amount of inclusions will be formed to wrap the effective ingredients, causing the loss of effective ingredients. At the same time, it will also cause the precipitate to stick together and be difficult to filter and separate. The current solution to this problem is usually to increase the stirring speed to allow the ethanol to diffuse quickly and break up the formed inclusions, thereby promoting the extraction of the effective ingredients. However, too high a stirring speed will cause the impurities to be broken, resulting in a smaller particle size of the impurities generated subsequently, which not only increases the difficulty of subsequent filtration, but also easily causes part of the filtrate to be mixed in the impurities, causing the loss of effective ingredients. Therefore, in view of this, the inventor provides an alcohol precipitation liquid preparation device for the root extract of torch flower to solve the above problems. Summary of the invention

[0005] The invention aims to solve the problem that in the traditional alcohol precipitation liquid preparation process, the local ethanol concentration is too high to form a large number of wrappings to wrap the effective ingredients, resulting in the loss of the effective ingredients.

[0006] In order to achieve the above-mentioned object, the basic scheme of the present invention provides a device for preparing alcohol precipitation liquid of the root extract of torch flower, comprising:

[0007] A support assembly, the support assembly comprising a frame and end covers symmetrically arranged on the frame;

[0008] A mixing assembly, the mixing assembly comprising a drum rotatably connected between the end covers and an ethanol feeding cylinder disposed between the end covers and located inside the drum, the inner wall of the drum being evenly provided with a plurality of baffles, and the side walls of the end covers being provided with a clear paste feeding pipe and an alcohol precipitation liquid discharging pipe respectively connected to the drum and an ethanol feeding pipe connected to the ethanol feeding cylinder;

[0009] The driving assembly includes a power piece and a first transmission mechanism which is arranged between the power piece and the roller and drives the roller to rotate.

[0010] The principles and effects of this basic solution are:

[0011] Compared with the prior art, the present invention provides a drum and baffles on the inner wall of the drum, so that when the driving mechanism drives the drum to rotate, the baffles drive the clear paste in the drum to rotate, so that the ethanol flowing out of the ethanol supply cylinder contacts with the clear paste at different positions, thereby avoiding the problem of excessive local ethanol concentration forming a large amount of wrappings that wrap the effective ingredients and cause the loss of effective ingredients. At the same time, the present invention can maintain the uniformity of ethanol distribution at a relatively low rotation speed, and can effectively avoid the problem of increased difficulty in subsequent filtration due to the small impurity particle size caused by excessive stirring speed.

[0012] Furthermore, the mixing assembly further comprises:

[0013] A first partition disposed on the ethanol supply cylinder, wherein the first partition divides the interior of the ethanol supply cylinder into at least two supply chambers respectively connected to the ethanol feed pipe, and a side wall of each supply chamber is provided with a supply hole connected to the drum;

[0014] A rotating cover rotatably connected to the outer wall of the ethanol supply cylinder and capable of covering the supply hole;

[0015] A sleeve rotatably connected to the end cover, one end of the sleeve extending into the drum and connected to the end of the rotating cover;

[0016] The driving assembly further comprises a second transmission mechanism which is arranged between the power member and the sleeve and drives the sleeve to rotate intermittently.

[0017] Through the above arrangement, ethanol can be temporarily stored in each feeding chamber, so that the uniformity of the distribution of ethanol along the axial direction of the ethanol feeding cylinder when mixing with the clear paste can be maintained at a lower ethanol flow rate, thereby avoiding the problem of impurities being dispersed due to excessive ethanol flow rate.

[0018] Further, the ethanol feed pipe comprises:

[0019] A first connecting section connected to the ethanol supply cylinder, the end of the first connecting section being rotatably sealed and connected to the inside of one end of the sleeve, a second partition corresponding to the position of the first partition being provided in the first connecting section, the second partition dividing the inside of the first connecting section into feed channels respectively connected to each feed cavity;

[0020] A second connecting section connected to the other end of the sleeve in a rotationally sealed manner;

[0021] The inner wall of the sleeve is provided with a protrusion which can block several feed channels therein.

[0022] With this arrangement, the sleeve is driven to rotate by the driving assembly to drive the protrusion to rotate, thereby facilitating adjustment of the ethanol feed pipe to communicate with different feed chambers, so that ethanol can be temporarily stored in each feed chamber, thereby improving the uniformity of ethanol distribution along the axial direction of the ethanol feed barrel.

[0023] Furthermore, the mixing assembly further includes a uniform distribution groove disposed between the end covers, the uniform distribution groove is located in the drum and below the ethanol feed cylinder, the uniform distribution groove is connected up and down and a flared opening is provided on the top of the uniform distribution groove, and ethanol is mixed with the clear paste through the ethanol feed pipe, the ethanol feed cylinder, and the uniform distribution groove. Providing the uniform distribution groove can further improve the uniformity of mixing ethanol and the clear paste.

[0024] Furthermore, the first transmission mechanism comprises:

[0025] A main shaft, drivingly connected to the output end of the power member;

[0026] A gear ring, sleeved on the outer wall of the drum;

[0027] The gear set comprises a plurality of gears meshing with the ring gear, wherein one of the gears is coaxially connected with the main shaft.

[0028] The main shaft drives one of the gears to rotate, so that the gear meshes with the ring gear, thereby driving the ring gear and the drum to rotate as a whole, thereby driving the drum to rotate compactly.

[0029] Furthermore, the support assembly further comprises limiting grooves symmetrically arranged on both sides of the drum and a plurality of rollers arranged on the frame and rollingly connected to the limiting grooves. The rollers cooperate with the limiting grooves to limit and guide the rotation of the drum, further improving the compactness of the drum rotation.

[0030] Furthermore, the second transmission mechanism comprises:

[0031] A transmission shaft, drivingly connected to the main shaft;

[0032] A fan gear, coaxially connected to the transmission shaft;

[0033] The sleeve gear is arranged on the outer wall of the sleeve and can mesh with the fan gear.

[0034] The cooperation between the fan gear and the sleeve gear is utilized to drive the sleeve gear to rotate intermittently, so that the ethanol feed pipe is connected with different feed chambers.

[0035] Furthermore, the ratio of the number of teeth of the sleeve gear to the number of teeth of the fan gear is the same as the number of feed chambers, so that the ethanol feed pipe is adjusted to communicate with different feed chambers, so that ethanol can be temporarily stored in each feed chamber, thereby improving the uniformity of ethanol distribution along the axial direction of the ethanol feed cylinder.

[0036] Furthermore, the support assembly further comprises a cylinder cover arranged between the end covers, and the roller is arranged below the cylinder cover, and the cylinder cover plays a protective role on the roller and the driving assembly.

[0037] Based on the same inventive concept, the present invention provides a method for preparing an alcohol precipitation liquid of a torch flower root extract, comprising using the above-mentioned alcohol precipitation liquid preparation device to prepare an alcohol precipitation liquid of the torch flower root extract, the steps being as follows:

[0038] Step S1, introducing a clear paste having a temperature of 30 to 50° C. and a relative density of 1.05 to 1.07 into the drum through a clear paste feeding pipe;

[0039] Step S2, driving the drum to rotate by the driving assembly, and simultaneously introducing ethanol with a volume fraction of 85-95% into the ethanol supply cylinder through the ethanol feed pipe, and the ethanol enters the drum through the ethanol feed pipe and the ethanol supply cylinder to mix with the clear paste until the alcohol precipitation liquid content in the drum reaches 70-80%;

[0040] Step S3, the alcohol precipitation liquid is discharged from the alcohol precipitation liquid discharge pipe, cooled to 2-10° C., and allowed to stand.

[0041] Compared with the prior art, the present invention provides a drum and baffles on the inner wall of the drum, so that when the driving mechanism drives the drum to rotate, the baffles drive the clear paste in the drum to rotate, so that the ethanol flowing out of the ethanol supply cylinder contacts with the clear paste at different positions, thereby avoiding the problem of excessive local ethanol concentration forming a large amount of inclusions that wrap the effective ingredients and cause the loss of effective ingredients. At the same time, the present invention can maintain the uniformity of ethanol distribution at a lower rotation speed, and can effectively avoid the problem of increased difficulty in subsequent filtration due to the small impurity particle size caused by excessive stirring speed.

[0051] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined invention purpose, the specific implementation mode, structure, characteristics and effects of the present invention are described in detail below in combination with the accompanying drawings and preferred embodiments.

[0052] The reference numerals in the drawings of the specification include: frame 1, cylinder cover 2, end cover 3, motor 4, driving pulley 5, driven pulley 6, transmission box 7, ethanol feed pipe 8, alcohol precipitation liquid discharge pipe 9, drum 10, ring gear 11, gear 12, limit groove 13, roller 14, main shaft 15, transmission shaft 16, driving gear 17, driven gear 18, fan gear 19, sleeve gear 20, sleeve 21, baffle 22, ethanol feed cylinder 23, rotating cover 24, first connecting section 25, protrusion 26, first partition 27, second partition 28, uniformly distributed groove 29, sealing ring 30.

[0053] A device for preparing alcohol precipitation liquid of torch flower root extract, for example Figure 1 As shown: It includes a support component, a mixing component and a driving component arranged on the support component, as follows:

[0054] Support components: such as Figure 1 As shown, the support assembly includes a frame 1, end covers 3 symmetrically arranged on the frame 1, a cylinder cover 2 arranged between the two end covers 3, and a transmission box 7 arranged on the side of one of the end covers 3. The frame 1 is welded and fixed with multiple channel steels, serving as the supporting basis of the entire alcohol precipitation liquid preparation device. The end covers 3, the cylinder cover 2 and the transmission box 7 are connected to each other or to the frame 1 by bolts or rivets, providing a relatively stable installation environment and operating environment for the mixing assembly.

[0055] Mixed components: e.g. Figure 2 As shown, the mixing assembly includes a roller 10 rotatably connected between the end covers 3, and the end covers 3 are each provided with a sealing ring 30 on one side close to the roller 10 and rotatably sealed with the end surface of the roller 10, as shown in FIG. Figure 4 , 6 As shown in FIG. 7 , a plurality of inclined baffles 22 are evenly arranged on the inner wall of the drum 10, and the inclination direction of the baffles 22 is the same as the rotation direction of the drum 10, so that the clear paste can be accumulated on the baffles 22, thereby facilitating the baffles 22 to drive the clear paste to move. The mixing assembly also includes an ethanol supply cylinder 23 and a uniform distribution groove 29 arranged between the end covers 3, wherein both ends of the ethanol supply cylinder 23 and the uniform distribution groove 29 are respectively fixed to the rotating covers 24 on both sides, the ethanol supply cylinder 23 is arranged coaxially with the drum 10, and the uniform distribution groove 29 is located below the ethanol supply cylinder 23.

[0056] like Figure 1As shown, the side walls of the right end cover 3 are respectively provided with an alcohol precipitate discharge pipe 9 connected to the bottom of the drum 10 and an ethanol feed pipe 8 connected to the ethanol feed barrel. Correspondingly, the side walls of the left end cover 3 are also provided with a clear paste feed pipe connected to the drum 10. The clear paste feed pipe, the ethanol feed pipe 8 and the alcohol precipitate discharge pipe 9 are all equipped with valves and pump bodies. Due to the wall thickness of the alcohol precipitate discharge pipe 9 itself and the assembly requirements, there may be a height difference between the lowest point of the end face of the alcohol precipitate discharge pipe 9 and the bottom of the barrel 10, resulting in the alcohol precipitate being unable to flow out completely or the cleaning liquid being unable to be completely discharged when cleaning the drum. In this embodiment, an alcohol precipitate discharge hole is opened on the side of the end cover 3, such as Figure 8 As shown, the right end surface of the drum 3 and the bottom surface of the alcohol precipitation liquid discharge hole are both arranged to be inclined downward to the right, and the bottom of the drum is connected to the alcohol precipitation liquid discharge pipe 9 through the alcohol precipitation liquid discharge hole, thereby avoiding the above-mentioned problem.

[0057] Since ethanol will produce gas during the mixing process with the clear paste, in order to ensure the stability of the air pressure in the drum 10 and ensure the safe production of the alcohol precipitation liquid preparation process, a respirator connected to the drum is installed at the rear corner of the end cover 3 on one side for gas exhaust. Figure 6 It can be seen that when the paste or alcohol precipitate rotates to the top or back side along the inner wall of the drum 10 driven by the baffle 22, it will fall back to the bottom of the drum under the action of its own gravity, thereby preventing the paste or alcohol precipitate from being discharged from the respirator.

[0058] like Figure 6 and Figure 7 As shown, a first partition 27 is provided in the ethanol feed cylinder 23, and the first partition 27 divides the interior of the ethanol feed cylinder 23 into two feed chambers, namely a left feed chamber and a right feed chamber. The bottoms of the left feed chamber and the right feed chamber are provided with a plurality of feed holes connected to the drum 10, and the top of the first partition 27 is provided with an air guide hole that connects the left feed chamber and the right feed chamber, and the height of the air guide hole is higher than the height of the ethanol page of the left feed chamber or the right feed chamber, the uniformly distributed groove 29 is connected up and down and the top of the uniformly distributed groove 29 is provided with a flared opening, and all the feed holes are located above the flared opening.

[0059] like Figure 6 and Figure 7 As shown, a rotating cover 24 is provided on the outer wall of the ethanol supply cylinder 23, and the arc surface of the rotating cover 24 is half of the ethanol supply cylinder 23, covering the supply hole of the left supply cavity or the right supply cavity, so that the left supply cavity or the right supply cavity is only connected to the inside of the drum 10 separately.

[0060] Driving assembly: The driving assembly includes a power member installed on the frame 1, a first transmission mechanism provided at the output end of the power member and driving the roller 10 to rotate, and a second transmission mechanism provided at the output end of the power member and driving the rotating cover 24 to rotate intermittently.

[0061] like Figure 1 and Figure 2 As shown, the power part adopts a motor 4 which can be controlled by a PLC controller or a single-chip microcomputer controller, and the first transmission mechanism includes a main shaft 15 arranged at the lower rear side of the drum 10 and rotatably connected to the frame 1, a ring gear 11 sleeved on the middle part of the circumference of the drum 10, and two gears 12 meshing with the ring gear 11, wherein the main shaft 15 is connected to the output shaft of the motor 4 through a belt drive. In this embodiment, a driving pulley 5 with a smaller diameter is coaxially connected to the output shaft of the motor 4, and a driven pulley 6 with a larger diameter is coaxially connected to the main shaft 15, thereby achieving the purpose of speed reduction transmission, the rear gear 12 is coaxially connected to the main shaft 15 and meshes with the ring gear 11, and the front gear 12 is rotatably connected to the frame 1 and meshes with the ring gear 11.

[0062] In order to improve the rotation stability of the drum 10 , limiting grooves 13 are provided on both sides of the drum 10 , and rollers 14 rollingly connected to the limiting grooves 13 are symmetrically provided on the frame 1 , thereby limiting and guiding the rotation of the drum 10 .

[0063] like Figure 2 and 3 As shown, the second transmission mechanism includes a transmission shaft 16 rotatably connected in the transmission box 7, a fan gear 19 coaxially connected to the transmission shaft 16, and a sleeve gear 20 that can mesh with the fan gear 19, wherein the transmission shaft 16 is connected to the main shaft 15 through a pair of gears 12. In this embodiment, the driving gear 17 is coaxially connected to the main shaft 15, and the driven gear 18 is coaxially connected to the transmission shaft 16. A sleeve 21 is also rotatably connected in the transmission box 7, one end of the sleeve 21 extends into the drum 10 and is connected to the end of the rotating cover 24, the sleeve gear 20 is arranged on the sleeve 21, and the number of teeth of the fan gear 19 is half of the sleeve gear 20, so as to drive the sleeve 21 and the rotating cover 24 to perform 180° intermittent rotation.

[0064] like Figure 5 As shown, the ethanol feed pipe 8 is composed of two sections, including a first connecting section 25 and a second connecting section. One end of the first connecting section 25 is rotatably sealed and connected to the inner wall of the sleeve 21, and the other end of the first connecting section 25 extends into the drum 10 and is connected to the ethanol supply cylinder 23. The first connecting section 25 is provided with a second partition 28 corresponding to the position of the first partition 27. The second partition 28 divides the interior of the first connecting section 25 into two feed channels connected to the left feed cavity and the right feed cavity respectively, namely the left feed channel and the right feed channel. The second connecting section is rotatably sealed and connected to the inner wall of the other end of the sleeve 21. The inner wall of the sleeve 21 is provided with a protrusion 26 that can block the left feed channel or the right feed channel, and the position of the protrusion 26 is opposite to the rotating cover 24.

[0065] In implementation, first, a clear paste with a temperature of 40-60° C. and a relative density of 1.05-1.07 is introduced into the drum 10 through the clear paste feeding pipe, and then the motor 4 is started. The motor 4 drives the main shaft 15 to rotate through the belt transmission, and the engagement of the gear 12 and the ring gear 11 drives the drum 10 to rotate. At the same time, ethanol with a volume fraction of 85-95% is continuously introduced into the ethanol feeding cylinder 23 through the ethanol feeding pipe 8. Driven by the second transmission mechanism, ethanol intermittently enters each feeding cavity and is mixed with the clear paste through the uniformly distributed groove 29. When the alcohol precipitate content in the drum reaches 70-80%, the alcohol precipitate is discharged from the alcohol precipitate discharge pipe 9, and the alcohol precipitate is cooled to 2-10° C. and then left to stand, and solid-liquid separation is performed.

[0066] Since the drum 10 and the ethanol feeding cylinder 23 have a certain axial length, in order to make the ethanol evenly distributed along the axial direction, the pump body needs to increase the pressure on the ethanol and increase its flow rate. However, excessive ethanol flow rate and flow pressure will cause the impurities in the clear paste to be dispersed, resulting in a smaller particle size of impurities generated subsequently, which increases the difficulty of subsequent filtration. To this end, in this embodiment, while the main shaft 15 rotates, the transmission shaft 16 is driven to rotate through the gear pair 12. The transmission shaft 16 drives the sleeve gear 20 to engage through the engagement of the fan gear 19 and the sleeve gear 20, so that the sleeve 21 and the rotating cover 24 rotate intermittently, that is, when the feed hole of the left feed chamber is connected to the drum 10, the feed hole of the right feed chamber is covered and blocked by the rotating cover 24, and the protrusion 26 blocks the left feed channel. Ethanol enters the right feed chamber through the second connecting section, the sleeve 21, and the right feed channel for storage, and the ethanol in the left feed chamber falls into the uniform distribution groove 29 through the corresponding feed hole, and passes through the uniform distribution groove 29 to mix with the clear paste. Thereby, ethanol can be temporarily stored in each feeding cavity, and the uniformity of the distribution of ethanol along the axial direction of the ethanol feeding cylinder 23 when the ethanol and the clear paste are mixed can still be maintained at a lower ethanol flow rate, so as to avoid the problem of impurities being dispersed due to excessive ethanol flow rate.

[0067] Based on the same inventive concept, the present invention provides a method for preparing an alcohol precipitation liquid of a torch flower root extract, comprising using the above-mentioned alcohol precipitation liquid preparation device to prepare an alcohol precipitation liquid of the torch flower root extract, the steps being as follows:

[0068] Step S1, passing a paste having a temperature of 30 to 50° C. and a relative density of 1.05 to 1.07 into the drum 10 through a paste feeding pipe;

[0069] Step S2, starting the motor 4, the motor 4 drives the main shaft 15 to rotate through the belt drive, and drives the drum 10 to rotate by the meshing of the gear 12 and the gear ring 11, and at the same time, ethanol with a volume fraction of 85-95% is introduced into the ethanol feeding cylinder 23 through the ethanol feeding pipe 8. Driven by the second transmission mechanism, the ethanol intermittently enters each feeding cavity and is mixed with the clear paste through the uniform distribution groove 29 until the alcohol precipitation liquid content in the drum 10 reaches 80%;

[0070] Step S3, the alcohol precipitation liquid is discharged from the alcohol precipitation liquid discharge pipe 9, cooled to 2-10° C., and allowed to stand.

[0071] This method can avoid the problem of excessive local ethanol concentration forming a large amount of inclusions that wrap the effective ingredients and cause the loss of effective ingredients. At the same time, the present invention can maintain the uniformity of ethanol distribution at a lower rotation speed and a lower ethanol flow rate, and can effectively avoid the problem of increased difficulty in subsequent filtration due to the small impurity particle size caused by excessive stirring speed.

[0072] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any form. Although the present invention has been disclosed as a preferred embodiment as above, it is not used to limit the present invention. Any technical personnel in this field can make some changes or modify the technical contents disclosed above into equivalent embodiments without departing from the scope of the technical solution of the present invention. However, any brief modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention are still within the scope of the technical solution of the present invention.
