Description

Technical Field

[0001] The invention relates to the technical field of Chinese medicine extract spray drying equipment, in particular to an anti-caking Chinese medicine extract spray drying machine. Background Art

[0002] In the preparation process of Chinese patent medicine, it is necessary to extract the effective ingredients from Chinese medicinal materials. First, the Chinese medicinal materials need to be boiled into a medicinal soup, and then the medicinal soup is subjected to multi-stage treatment to form a viscous slurry flow, and then the slurry material is dried to form particles. In order to achieve rapid and thorough drying of the particles, the viscous slurry is usually atomized and then fully contacted with hot air to complete the drying.

[0003] The existing Chinese medicine spray drying device uses a high-speed centrifugal atomizer to atomize the viscous liquid material, and then fully contact with hot air to complete instant drying to form a powder or small granular finished product. However, in actual operation, the particles after the medicine mist is dried fall along the cavity wall, and the temperature drop is easy to cause the powder to absorb moisture and condense again, resulting in incomplete drying; A Chinese patent with publication number CN112403004B discloses an anti-caking Chinese medicine extract spray dryer, in which a partition separates the drying cylinder into a breathing chamber located above the partition and a drying chamber located below the partition, and a plurality of air ports connecting the breathing chamber and the drying chamber are provided on the partition, and the plurality of air ports are distributed along the side wall of the drying chamber, and a movably mounted filter plate is provided at each air port, and the filter plate is opened as air enters the air port and is closed as air is discharged from the exhaust port. This patent sets a breathing chamber in the drying cylinder, and drives the filter plate switch by exhaling and inhaling into the drying chamber through the air port. When the atomizing nozzle sprays, the atomized material is isolated from the cylinder wall by exhaling. When the atomizing nozzle stops, air is inhaled again through the air hole to extract the separated water vapor, thereby reducing the humidity in the drying cylinder, thereby preventing the dried powder from contacting the cylinder wall and absorbing moisture to form agglomerates. The patent uses the method of heating the medicine mist by exhaling into the drying chamber through the air port. In actual operation, the closer the medicine mist is to the bottom of the drying cylinder, the lower the heating efficiency will be. In addition, the method of blowing directly into the drying chamber through the air port will cause the heating time of the medicine mist in the drying cylinder to be too short, resulting in uneven heating of the medicine mist, and the work efficiency needs to be improved. Summary of the invention

[0004] The present invention discloses an anti-caking Chinese medicine extract spray dryer, which aims to solve the technical problems that in the above-mentioned comparative documents, the method of heating the medicine mist by exhaling into a drying chamber through an air port will result in lower heating efficiency of the medicine mist closer to the bottom in the drying cylinder during actual operation, and the method of directly blowing into the drying chamber through the air port will result in too short heating time of the medicine mist in the drying cylinder, thereby causing uneven heating of the medicine mist and the working efficiency needs to be improved.

[0005] In order to achieve the above object, the present invention adopts the following technical solutions: A traditional Chinese medicine extract spray dryer for preventing caking comprises a machine body, a medicine guide tube installed through the top of the machine body, an atomizing nozzle installed at the end of the medicine guide tube, the atomizing nozzle is distributed inside the machine body, and an air induction sleeve installed through the top of the machine body, and a drying mechanism for uniformly heating the medicine mist and preventing the medicine powder and medicine granules from caking is arranged inside the machine body; The drying mechanism includes a partition fixedly installed on the upper part of the body, and the bottom of the partition is connected with a plurality of air guides for introducing hot air, and the air guides are fixedly installed on the inner wall of the body; a plurality of dehumidification components for extracting water vapor are installed inside the partition.

[0006] A drying mechanism is provided inside the machine body to evenly heat the medicine mist and prevent the powder and granules from agglomerating. The hot air generated by the air induction sleeve is evenly introduced into the machine body by using partitions and air guides. At the same time, the air guides are used to make the hot air introduced into the machine body to be distributed in a spiral shape, thereby reducing the settling speed of the medicine mist. As a result, the medicine mist has more time to be heated and is heated evenly. At the same time, the additional dehumidification component is used to maintain the dryness inside the machine body, thereby preventing the medicine mist from agglomerating, thereby greatly improving the working efficiency and functionality of the traditional spray dryer.

[0007] In a preferred embodiment, the drying mechanism also includes the partition that divides the interior of the body into a heat conduction zone and a heating zone, the air induced sleeve is connected to the interior of the heat conduction zone, the atomizing nozzle introduces medicine mist into the interior of the heating zone, and the air guide is distributed inside the heating zone.

[0008] The interior of the machine body is divided into two sections by a partition; the interior of the induced draft sleeve and the heat transfer section are connected, the induced draft sleeve guides the hot air into the heat transfer section, and cooperates with the operation of the air guide member to guide the hot air into the heating section. With the backdraft of the induced draft sleeve, the moisture generated inside the machine body will be discharged out of the machine body through the heat transfer section by the induced draft sleeve, thereby ensuring the integrity of the operation of the equipment.

[0009] In a preferred embodiment, the air guide member includes a plurality of air guide ducts connected to the partition plate, the air guide ducts are fixedly installed on the inner wall of the body, a grid plate is fixedly installed on the side wall of each of the air guide ducts, a plurality of air inlets are evenly arranged inside the grid plate, and a type of flap is rotatably installed inside each of the air inlets.

[0010] By configuring the air guide component to consist of an air guide duct, a grid plate and a type of flap, when the air induced sleeve guides hot air into the interior of the heat transfer zone, the hot air can push the type of flap to rotate, thereby entering the interior of the machine body through the air guide duct, the grid plate and the air inlet, thereby drying the medicine mist. At the same time, accompanied by the reverse suction of the air by the air induced sleeve, the type of flap affected by the suction force will be in a closed state, thereby controlling the one-way flow of the air path inside the machine body, cooperating with the operation of the dehumidification component, and ensuring the integrity of the operation of the equipment. At the same time, the inclined air inlet can introduce hot air into the interior of the machine body, causing the hot air to be distributed in a vortex shape, thereby stirring the medicine mist inside the machine body, reducing the sedimentation rate of the medicine mist, and allowing the medicine mist to have more drying time.

[0011] In a preferred embodiment, the dehumidification element includes a plurality of frame members installed inside the partition, a second type flap is rotatably installed on the top of each frame member, and a filter is installed inside each frame member.

[0012] By configuring the dehumidification component to consist of a frame, two types of flaps and a filter, when the induced draft sleeve guides the hot air into the heat transfer zone, the hot air will push the two types of flaps to close, and along with the reverse suction of the induced draft sleeve, the two types of flaps affected by the suction force will be in an open and closed state, thereby controlling the one-way flow of the air path inside the machine body, and being filtered by the filter, the single moisture is filtered away, thereby ensuring the dryness inside the machine body, cooperating with the operation of the air guide component to ensure the integrity of the operation of this equipment.

[0013] In a preferred solution, the dehumidifying component further includes a plurality of moisture drainage ports on the top of each of the second type flaps, and a circle of moisture drainage holes is formed through the top of the body.

[0014] By providing a number of moisture drain ports and holes, part of the moisture inside the machine body can be discharged as soon as the equipment dries the medicine mist, thereby stabilizing the air pressure inside the machine body and ensuring the integrity of the equipment operation.

[0015] As can be seen from the above, the anti-caking Chinese medicine extract spray dryer provided by the present invention has the following improvements and advantages compared with the prior art: First, a drying mechanism is provided inside the machine body, and the interior of the machine body is divided into two sections by a partition. The interior of the induced draft sleeve and the heat transfer section are connected, and the induced draft sleeve can introduce hot air into the interior of the heat transfer section, and then evenly introduce the hot air into the interior of the heating section through the air guide, so that the medicine mist at the top and bottom of the heating section can be heated more evenly. At the same time, when the induced draft sleeve starts to reversely suck air, the smoke exhausted from the interior of the machine body is filtered in conjunction with an additional dehumidification component, and the single moisture is discharged from the interior of the machine body, thereby maintaining the dryness of the interior of the machine body, preventing the medicine mist from agglomerating, and greatly improving the working efficiency and functionality of the traditional spray dryer.

[0016] Second, the air guide component is composed of an air guide duct, a grid plate and a first-class flap. When the draft sleeve guides hot air into the interior of the heat transfer zone, the hot air can push the first-class flap to rotate, thereby entering the interior of the machine body to dry the medicine mist. At the same time, accompanied by the reverse suction of the draft sleeve, the first-class flap affected by the suction force will be in a closed state, and the dehumidification component is arranged to be composed of a frame member, a second-class flap and a filter. When the draft sleeve guides hot air into the interior of the heat transfer zone, the hot air will push the second-class flap to close, and accompanied by the reverse suction of the draft sleeve The second type of flap affected by the suction force will be in an open and closed state, thereby controlling the one-way flow of the air path inside the machine body, and being filtered by the filter disc, filtering out the single moisture, thereby maintaining the dryness inside the machine body, cooperating with the operation of the air guide to ensure the integrity of the operation of this equipment; at the same time, the inclined air inlet can introduce hot air into the machine body, causing the hot air entering the machine body to be distributed in a vortex shape, thereby stirring the medicine mist inside the machine body, reducing the sedimentation rate of the medicine mist, resulting in more drying time for the medicine mist, and improving the quality of the finished product.

DETAILED DESCRIPTION

[0028] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0029] The anti-caking Chinese medicine extract spray dryer disclosed by the invention is mainly used for drying the Chinese medicine extract mist to prepare medicine powder and medicine granules.

[0030] Reference Figures 1 to 10 A spray dryer for anti-caking Chinese medicine extract comprises a machine body 1, a drug guide tube 2 installed through the top of the machine body 1, an atomizing nozzle 3 installed at the end of the drug guide tube 2, the atomizing nozzle 3 is distributed inside the machine body 1, and an air induction sleeve 4 installed through the top of the machine body 1, and a drying mechanism 5 for uniformly heating the drug mist and preventing the drug powder and granules from agglomerating is arranged inside the machine body 1; The drying mechanism 5 includes a partition 501 fixedly installed on the upper part of the body 1, and a plurality of air guides 504 for introducing hot air are connected to the bottom of the partition 501, and the air guides 504 are fixedly installed on the inner wall of the body 1; a plurality of dehumidification components 505 for extracting water vapor are installed inside the partition 501.

[0031] In this embodiment: before use, the medicine guide tube 2 is connected to the external medicine tank and pump device, and the air-inducing sleeve 4 is connected to the external negative pressure fan device; the user starts the whole device, and introduces the medicine liquid into the interior of the atomizing nozzle 3 through the medicine guide tube 2. The atomizing nozzle 3 pressurizes the medicine liquid into medicine mist and sprays it into the interior of the body 1. At the same time, the negative pressure fan device connected to the air-inducing sleeve 4 is started, and hot air is introduced into the interior of the body 1 through the air-inducing sleeve 4. During this process, the dehumidification component 505 is closed, and the hot air entering the interior of the body 1 will be evenly dispersed in the interior of the body 1 through the air-inducing component 504, thereby heating and drying the medicine mist, drying the moisture in the medicine mist, causing the medicine mist to become medicine powder and medicine particles and be discharged from the bottom of the body 1. At the same time, when the body After the drying process of the medicine mist is completed, the operator controls the reverse rotation of the negative pressure fan device connected to the air-inducing sleeve 4, so that negative pressure is generated inside the air-inducing sleeve 4 and the inside of the machine body 1 is exhausted. In this process, the air guide 504 is closed, so that the moisture inside the machine body 1 is discharged through the open and closed dehumidification component 505. The dehumidification component 505 intercepts the fine medicine powder and particles in the moisture, and the moisture is discharged from the machine body 1. Among them, a heating pump 6 is fixedly installed in the middle of the air-inducing sleeve 4. When the air-inducing sleeve 4 is driven by the external negative pressure fan device to introduce air into the inside of the machine body 1, the heating pump 6 starts to heat the air flowing through the inside of the air-inducing sleeve 4, so that the hot air enters the inside of the machine body 1.

[0032] Further, it is supplemented that: a fan 8 is installed at the bottom of the body 1, and a cyclone separator 7 is installed through the bottom side of the body 1. The finished products of medicine particles and powders dried by hot air will float and accumulate at the bottom of the body 1. At this time, the fan 8 and the cyclone separator 7 are turned off and started synchronously to peel the medicine particles and powders from the inside of the body 1 to obtain the finished products.

[0033] In the above scheme, in order to prevent the powder and granules formed after the drug mist dries inside the body 1 from falling along the cavity wall of the body 1, the powder absorbs moisture and condenses again due to the temperature drop, resulting in incomplete drying, the specific operation is as follows.

[0034] Reference Figures 1 to 10 In a preferred embodiment, the drying mechanism 5 also includes a partition 501 that divides the interior of the body 1 into a heat conduction zone 502 and a heating zone 503, the air induced sleeve 4 is connected to the interior of the heat conduction zone 502, the atomizing nozzle 3 introduces the medicine mist into the interior of the heating zone 503, and the air guide 504 is distributed inside the heating zone 503.

[0035] In this embodiment: the user starts the whole device, introduces the medicine liquid into the interior of the atomizing nozzle 3 through the medicine guiding tube 2, and the atomizing nozzle 3 pressurizes the medicine liquid into medicine mist and sprays it into the heating zone 503 inside the machine body 1. At the same time, the negative pressure fan device connected to the air induction sleeve 4 is started, and hot air is introduced into the interior of the machine body 1 through the air induction sleeve 4. The hot air will be pre-stored in the interior of the heat conduction zone 502. During this process, the dehumidification component 505 is closed, and then uniformly dispersed in the heating zone 503 inside the machine body 1 through the air guide component 504, so as to heat and dry the medicine mist and dry the moisture in the medicine mist. The medicine mist is turned into powder and particles and discharged from the bottom of the machine body 1. At the same time, when the machine body 1 completes the drying process of the medicine mist, the operator controls the negative pressure fan device connected to the draft sleeve 4 to reverse, so that negative pressure is generated inside the draft sleeve 4 and the interior of the machine body 1 is exhausted. During this process, the air guide member 504 is closed, so that the moisture inside the machine body 1 flows into the heat transfer zone 502 through the opened and closed dehumidification member 505. The dehumidification member 505 intercepts the fine powder and particles in the moisture, while the moisture is discharged from the draft sleeve 4 through the heat transfer zone 502 to the outside of the machine body 1.

[0036] Reference Figures 3 to 5 , Figures 8 to 10 In a preferred embodiment, the air guide member 504 includes a plurality of air guide ducts 5041 connected to the partition 501, the air guide ducts 5041 are fixedly installed on the inner wall of the body 1, and a grid plate 5042 is fixedly installed on the side wall of each air guide duct 5041, and a plurality of air inlets 5043 are evenly opened inside the grid plate 5042, and a type of flap 5044 is rotatably installed inside each air inlet 5043.

[0037] In this embodiment: the negative pressure fan device connected to the induced draft sleeve 4 is started, and hot air is introduced into the interior of the body 1 through the induced draft sleeve 4. The hot air will be pre-stored in the heat transfer zone 502. During this process, the dehumidification component 505 is closed, and the hot air in the heat transfer zone 502 will enter the interior of the air guide duct 5041 and push the first flap 5044, causing the first flap 5044 to rotate around the grid plate 5042, exposing the air inlet 5043, so that the hot air is evenly dispersed in the heating zone 503 inside the body 1 through the air inlet 5043, heating and drying the medicine mist, drying the moisture in the medicine mist, causing the medicine mist to become medicine powder and medicine particles and be discharged from the bottom of the body 1, and Several rows of air inlets 5043 are tilted, causing the hot air entering the heating zone 503 to flow in a vortex shape, thereby preventing the agglomeration of powder and granules while reducing the speed of drug mist settling, thereby improving the efficiency of drug mist drying. At the same time, when the machine body 1 completes the drying process of the drug mist, the operator controls the negative pressure fan device connected to the air induced sleeve 4 to reverse, causing negative pressure to be generated inside the air induced sleeve 4 and exhausting air into the machine body 1. In this process, a type of flap 5044 loses the wind pressure push in the direction of the air duct 5041 and will reset and rotate, thereby covering the air inlet 5043, causing the moisture inside the machine body 1 to flow into the heat transfer zone 502 through the opened and closed dehumidification component 505.

[0038] Further, it is supplemented that a plurality of evenly distributed slots 506 are provided through the interior of the partition 501 , each slot 506 corresponds to the top of an air guide 504 , and the air guide 504 is connected to the heat conduction zone 502 through the slot 506 .

[0039] In the above scheme, in order to maintain the dryness inside the body 1 and prevent the powder and granules from agglomerating, the specific operation is as follows.

[0040] Reference Figures 3 to 7 In a preferred embodiment, the dehumidification element 505 includes a plurality of frame members 5051 installed inside the partition 501, and a second-class flap 5052 is rotatably installed on the top of each frame member 5051, and a filter 5053 is installed inside each frame member 5051.

[0041] In this embodiment, the negative pressure fan device connected to the induced draft sleeve 4 is started, and hot air is introduced into the interior of the machine body 1 through the induced draft sleeve 4. The hot air is first stored in the interior of the heat transfer section 502. During this process, the hot air in the heat transfer section 502 cannot push the second type flap 5052 to flow through the frame opening 5051, so that the hot air in the heat transfer section 502 enters the interior of the air guide duct 5041 and pushes the first type flap 5044, causing the first type flap 5044 to flow around the grid plate. 5042 rotates to expose the air inlet 5043, so that the hot air is uniformly dispersed in the heating zone 503 inside the body 1 through the air inlet 5043, thereby heating and drying the medicine mist, drying the moisture in the medicine mist, causing the medicine mist to become medicine powder and medicine particles and be discharged from the bottom of the body 1, and several rows of air inlets 5043 are inclined, so that the hot air entering the heating zone 503 flows in a vortex shape, thereby preventing the powder and medicine particles from agglomerating and reducing the speed of the medicine mist settling, thereby improving the medicine mist The drying efficiency is affected. At the same time, when the machine body 1 completes the drying process of the medicine mist, the operator controls the reverse direction of the negative pressure fan device connected to the induced draft sleeve 4, so that negative pressure is generated inside the induced draft sleeve 4 and the inside of the machine body 1 is exhausted. In this process, the first type of flap 5044 loses the wind pressure push from the direction of the air guide duct 5041 and will reset and rotate, thereby covering the air inlet 5043, and the second type of flap 5052 will rotate around the frame opening 5051 due to the negative pressure adsorption, causing the frame opening 5051 to Expose, allowing the moisture inside the body 1 to flow into the heat conduction zone 502 through the open and closed frame member 5051. In this process, the powder and particles in the moisture will be intercepted by the filter 5053. Among them, the dehumidification component 505 also includes a plurality of dehumidification ports 5054 on the top of each second-class flap 5052, and a circle of dehumidification holes 9 is opened on the top of the body 1. When the equipment is running, moisture will also be generated inside the body 1. At this time, part of the moisture can be discharged through the dehumidification ports 5054 and the dehumidification holes 9.

[0042] Working principle: when in use, the medicine guide tube 2 is connected to the external medicine tank and pump device, and the air-inducing sleeve 4 is connected to the external negative pressure fan device; the user starts the whole device, and introduces the medicine liquid into the interior of the atomizing nozzle 3 through the medicine guide tube 2. The atomizing nozzle 3 pressurizes the medicine liquid into medicine mist and sprays it into the heating zone 503 inside the body 1. At the same time, the negative pressure fan device connected to the air-inducing sleeve 4 is started, and hot air is introduced into the interior of the body 1 through the air-inducing sleeve 4. The hot air will be pre-stored in the interior of the heat conduction zone 502. During this process, the hot air inside the heat conduction zone 502 cannot push the second type The flap 5052 flows through the frame opening 5051, so that the hot air in the heat conduction zone 502 enters the air duct 5041 and pushes the flap 5044, so that the flap 5044 rotates around the grid plate 5042, exposing the air inlet 5043, and the hot air is evenly dispersed in the heating zone 503 inside the body 1 through the air inlet 5043, so as to heat and dry the medicine mist and dry the moisture in the medicine mist, and several rows of air inlets 5043 are inclined, so that the hot air entering the heating zone 503 flows in a vortex shape (such as Figure 4 As shown), the medicine powder and granules are prevented from agglomerating and the speed of the medicine mist settling is reduced, and the medicine mist is prevented from contacting the inner wall of the machine body 1. The spiral airflow makes the medicine mist concentrate at the high temperature position in the center of the machine body 1 for drying, thereby improving the drying efficiency of the medicine mist. The finished products dried into granules and powders by the hot air will float and accumulate at the bottom of the machine body 1. At this time, the fan 8 and the cyclone separator 7 are started synchronously to peel the granules and powders from the inside of the machine body 1 to obtain the finished products. At the same time, when the machine body 1 completes the drying process of the medicine mist, the operator controls the negative pressure air connected to the air induction sleeve 4. The machine device is reversed, causing negative pressure to be generated inside the air induced sleeve 4 and exhausting air into the body 1. During this process, the first type of flap 5044 loses the wind pressure push from the direction of the air duct 5041 and will reset and rotate, thereby covering the air inlet 5043, and the second type of flap 5052 will rotate around the frame mouth piece 5051 due to the influence of negative pressure adsorption, causing the frame mouth piece 5051 to be exposed, allowing the moisture inside the body 1 to flow into the heat conduction zone 502 through the opened and closed frame mouth piece 5051. During this process, the powder and particles in the moisture will be intercepted by the filter 5053.
