Abstract
Description
Technical Field
[0001] This utility model relates to the field of spray drying technology, and in particular to a spray drying device for traditional Chinese medicine extracts. Background Technology
[0002] Traditional Chinese medicine extracts are semi-solid or solid preparations made from Chinese medicinal materials through extraction and concentration. They are one of the common forms of modern processing of Chinese medicine. They extract the effective components from medicinal materials and remove ineffective impurities through specific processes. They are characterized by small volume, high concentration of effective components, and ease of storage and further processing. Spray drying is a process that uses atomization and hot air to quickly dry materials. Its core principle is to atomize liquid or slurry materials into fine droplets. After contact with hot air, the water in the droplets evaporates rapidly, and finally, dry solid powder or granules are obtained.
[0003] Existing spray drying devices for traditional Chinese medicine extracts suffer from uneven particle distribution during drying. When the spray particles come into contact with the inner wall of the drying chamber, they are not completely dehydrated and quickly adhere to the inner wall, forming wet clumps. These clumps gradually accumulate and thicken, eventually charring and deteriorating, affecting the quality of subsequent batches of products. Furthermore, the clumps of powder tend to accumulate during collection, causing obstructed material flow and impacting machine efficiency. Therefore, a new spray drying device for traditional Chinese medicine extracts needs to be designed to address these issues. Utility Model Content
[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a spray drying device for traditional Chinese medicine extracts.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] A spray drying device for traditional Chinese medicine extract includes a housing. Multiple support legs are fixedly mounted on the upper surface of the housing. An air heater is fixedly mounted at the end of each support leg. The outlet end of the air heater communicates with the interior of the housing. A water pump is fixedly mounted on the upper surface of the housing. The water pump outlet pipe extends into the interior of the housing. An installation sleeve is rotatably mounted on the outer wall of the outlet pipe. A sprayer is fixedly mounted on the inner wall of the installation sleeve. A first motor is fixedly mounted on the upper surface of the housing. A pulley is fixedly mounted on both the output shaft of the first motor and the outer wall of the installation sleeve. The two pulleys are connected by a belt for transmission. A sieve plate is slidably mounted on the inner wall of the housing via an installation mechanism. Two first connecting rods are fixedly mounted on the lower surface of the sieve plate. Cranks are rotatably mounted at the ends of the two first connecting rods via a rotating mechanism. A second connecting rod is fixedly mounted between the two cranks. A second motor is fixedly mounted on the outer wall of the housing, and the second motor is fixedly connected to the outer wall of the crank on the same side.
[0007] Preferably, the installation mechanism includes support plates fixedly installed on the inner walls of both sides of the box, and the sieve plate is slidably installed on the upper surface of the two support plates.
[0008] Preferably, the rotating mechanism includes a rotating shaft fixedly installed at the end of the first connecting rod, and the end of the rotating shaft is rotatably connected to the inside of the crank.
[0009] Preferably, a drying sleeve communicating with the interior is fixedly installed on the outer wall of the air heater, and multiple drying plates are fixedly installed inside the drying sleeve.
[0010] Preferably, a vibrating motor is fixedly installed on each of the two outer side walls of the housing, and the two vibrating motors are arranged symmetrically.
[0011] Preferably, an air outlet pipe communicating with the interior is fixedly installed on the side wall of the housing, and an air outlet valve is fixedly installed at the end of the air outlet pipe.
[0012] The beneficial effects of this utility model are:
[0013] 1. By setting up components such as a first motor, pulley, mounting sleeve, and sprayer, the output shaft of the first motor drives the pulley to rotate, and the pulley drives the mounting sleeve on the inner wall of another pulley to rotate through the belt transmission, which can make the sprayer rotate at a uniform speed, thereby making the spray more uniform and reducing the adhesion of particles to the inner wall.
[0014] 2. By setting up components such as a sieve plate, a first connecting rod, a second connecting rod, a crank, and a second motor, the second motor can drive the two cranks to rotate through the second connecting rod when it is running. This causes the rotating shaft to drive the first connecting rod to move up and down. The two first connecting rods can drive the sieve plate to shake up and down repeatedly, which can prevent the accumulation of powder clumps during feeding and avoid affecting the feeding effect.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0022] Reference Figure 1-5A spray drying device for traditional Chinese medicine extract includes a housing 1. Multiple support legs 2 are fixedly installed on the upper surface of the housing 1. An air heater 3 is fixedly installed at the end of each support leg 2. The heater 3 serves as the core heat source during the drying process, integrating an electric heating wire and an intelligent temperature control system to rapidly heat the air to a set temperature. The outlet of the air heater 3 is connected to the interior of the housing 1, continuously supplying hot air for the drying process. A drying sleeve 4, connected to the interior, is fixedly installed on the outer wall of the air heater 3. Multiple drying plates are fixedly installed inside the drying sleeve 4 to ensure the hot air entering the housing 1 is properly cooled. In a dry state, a water pump 5 is fixedly installed on the upper surface of the chamber 1. The outlet pipe of the water pump 5 extends into the interior of the chamber 1. A mounting sleeve 6 is rotatably installed on the outer wall of the outlet pipe. A sprayer 7 is fixedly installed on the inner wall of the mounting sleeve 6, which greatly increases the contact area between the extract and the hot air, accelerating the drying process. A first motor 8 is fixedly installed on the upper surface of the chamber 1. Both the output shaft of the first motor 8 and the outer wall of the mounting sleeve 6 are fixedly installed with pulleys 9. The two pulleys 9 are connected by a belt, which allows the droplets to spread evenly in all directions under the action of centrifugal force, avoiding local accumulation and effectively reducing the adhesion phenomenon on the inner wall of the chamber 1. A sieve plate 11 is slidably mounted on the inner wall of the housing 1 via an installation mechanism. The installation mechanism includes support plates 10 fixedly mounted on the inner walls of both sides of the housing 1. The sieve plate 11 is slidably mounted on the upper surfaces of the two support plates 10. Two first connecting rods 12 are fixedly mounted on the lower surface of the sieve plate 11. Cranks 13 are rotatably mounted on the ends of the two first connecting rods 12 via a rotating mechanism. The rotating mechanism includes a rotating shaft fixedly mounted on the end of the first connecting rod 12. The end of the rotating shaft is rotatably connected to the inside of the crank 13. A second connecting rod 14 is fixedly mounted between the two cranks 13. The eccentric structure of the crank 13 pushes the first connecting rod 14. The connecting rod 12 moves up and down, which in turn causes the sieve plate 11 to sieve up and down repeatedly to prevent powder from clumping. A second motor 15 is fixedly installed on the outer wall of the box 1. The second motor 15 is fixedly connected to the outer wall of the crank 13 on the same side. Vibrating motors 16 are fixedly installed on both outer walls of the box 1. The two vibrating motors 16 are symmetrically arranged. The symmetrically installed vibrating motors 16 can counteract the horizontal force, prevent the box 1 from shifting and shaking, and reduce mechanical wear and local stress, so as to extend the service life of the equipment. An air outlet pipe communicating with the interior is fixedly installed on the side wall of the box 1. An air outlet valve 17 is fixedly installed at the end of the air outlet pipe.
[0023] When this utility model is in use, the air is dried by the drying sleeve 4 and then enters the air heater 3. After being heated by the air heater 3, it is introduced into the box 1. Then, the first motor 8 is started to drive the pulley 9 to rotate. Through the belt drive, the mounting sleeve 6 is rotated. The sprayer 7 at the end of the mounting sleeve 6 rotates accordingly. At the same time, the material pumped by the water pump 5 flows into the sprayer 7 through the outlet pipe. The material is evenly atomized and sprayed out as the sprayer 7 rotates. Under the action of hot air, the moisture in the droplets evaporates rapidly and is discharged through the air outlet valve 17. After drying, the material becomes powder and falls onto the upper surface of the sieve plate 11.
[0024] When sieving is required, the second motor 15 is started. The second motor 15 drives the two cranks 13 to rotate through the second connecting rod 14. The first connecting rod 12 can move up and down through the rotating shaft inside the crank 13. The screen plate 11 can be shaken up and down under the action of the first connecting rod 12 to prevent the dried material from accumulating on the upper surface of the screen plate 11. When material adheres to the inner wall of the box 1, the vibrating motor 16 can be started to knock off the adhered material through vibration.
[0025] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
