Technical Field
[0001] This utility model belongs to the field of medicine, and in particular relates to an integrated machine for concentrating and spray drying kudzu root extract. Background Technology
[0002] Kudzu root extract is a plant compound isolated from kudzu root, with its main active ingredient being isoflavone derivatives. Kudzu root extract has various medicinal uses, primarily for treating alcohol poisoning, retinal arteriovenous occlusion, hypertension, and hyperlipidemia. After extracting these active ingredients from kudzu root, it is converted into a powder form that is easy to store and use through concentration and drying processes.
[0003] However, in the existing kudzu root extract production process, the concentration and drying stages are usually carried out in a segmented operation mode. This operation mode not only prolongs the production cycle, but also increases production costs due to the need for more manpower to monitor the entire process. More seriously, since the concentration and drying processes are independent of each other, the extract will be exposed to the external environment for a long time during transportation and waiting, which not only increases the risk of contamination, but may also lead to the loss of effective ingredients, ultimately posing a serious threat to the purity and stability of the product. To address the above problems, there is a need for an integrated machine for the concentration and spray drying of kudzu root extract. Utility Model Content
[0004] In order to overcome the shortcomings of the existing kudzu root extract production process, which involves separate operations for concentration and drying, resulting in long production cycles, high costs, and increased risks of contamination and loss of effective ingredients, thus affecting product purity and stability, this utility model provides an integrated machine for kudzu root extract concentration and spray drying.
[0005] This utility model is achieved through the following technical approach: A kudzu root extract concentration and spray drying integrated machine, comprising a base, a first support, a concentration chamber, a first temperature control plate, a heating wire, a sealing plate, a stirring assembly, a feed pipe, an exhaust pipe, a vacuum pump, a discharge pipe, a material pump, a plate solenoid valve, and a control console. The first support is installed at the top of the base, and the concentration chamber is installed on the upper part of the first support in a sleeved manner. An annular cavity is formed in the inner wall of the concentration chamber, which is closed at the upper end and open at the lower end. The first temperature control plate is installed at the front of the concentration chamber, and the heating wire... The device is installed inside the annular cavity and electrically connected to the first temperature control plate. The sealing plate is installed at the lowest point of the annular cavity, with its bottom end flush with the bottom end of the annular cavity. The stirring assembly is located inside the concentration chamber. The feed pipe is fixed to the upper part of the concentration chamber, and the air outlet pipe is fixed to the upper part of the concentration chamber. The vacuum pump is installed on the air outlet pipe, and the discharge pipe is fixed to the bottom end of the concentration chamber. The material pump is installed at one end of the discharge pipe, and the plate solenoid valve is installed at the other end of the discharge pipe. The control console is installed on the top of the base and electrically connected to the vacuum pump, the material pump, and the plate solenoid valve.
[0006] In one embodiment, the drying assembly includes a second support, a heating ring, a second temperature control plate, a drying chamber, a discharge pipe, a discharge pump, and an atomizer. The second support is mounted on the top of the base and located to the right of the first support. The heating ring is mounted on the upper part of the second support. The second temperature control plate is mounted on the front of the heating ring and electrically connected to it. The drying chamber is mounted in the annular space of the heating ring in a sleeve-like manner. The discharge pipe is fixed to the bottom of the drying chamber. The discharge pump is mounted on the discharge pipe and electrically connected to the control console. The atomizer is mounted on the top of the drying chamber and electrically connected to the control console. One end of the discharge pipe is connected to the atomizer.
[0007] In one embodiment, the stirring assembly includes a motor, a drive gear, a driven gear, and stirring rods. The motor is mounted on the top of the concentration chamber via an L-shaped plate, with its output shaft facing downwards. The motor is electrically connected to the control console. A single drive gear is rotatably positioned at the top of the concentration chamber, with the motor's output shaft extending to the center of the drive gear. Multiple driven gears are arranged in a circular pattern around the motor's output shaft, rotatably positioned at the top of the concentration chamber, and uniformly distributed around the drive gear to mesh with it. Multiple stirring rods are distributed around the center of the drive gear, rotatably positioned inside the concentration chamber, with one end of each stirring rod extending to the outside of the concentration chamber and fixedly connected to a vertically aligned driven gear.
[0008] In one embodiment, the device further includes a limiting rod, a receiving box, locking blocks, and springs. The limiting rod is fixed to the top of the base and located below the drying chamber. The receiving box is slidably placed on the top of the base and located below the discharge pipe, slidingly engaging with the limiting rod. The receiving box and the discharge pipe are vertically aligned. Two locking blocks are arranged side by side and slidably disposed on the limiting rod. Two springs are arranged side by side inside the limiting rod, with each end of the spring fixedly connected to the limiting rod and the corresponding locking block, respectively.

[0012] 2. By adding a stirring component, the extract can be fully stirred and mixed during the concentration process, ensuring that the extract is heated evenly and avoiding local overheating that could lead to extract denaturation or loss of active ingredients. At the same time, it accelerates the evaporation of water in the extract, increases the concentration speed, and shortens the processing time.
[0013] 3. Through the cooperation of the limiting rod and the receiving box, the powder discharged from the discharge pipe can be collected in a concentrated manner, and through the action of the locking block and spring, the receiving box can be stably limited on the base and easily disassembled.

[0019] Example: An integrated machine for concentrating and spray drying kudzu root extract, such as... Figures 1-3As shown, the system includes a base 1, a first support 2, a concentration chamber 3, a first temperature control plate 31, a heating wire 32, a sealing plate 33, a stirring assembly, a feed pipe 4, a sealing plug 41, an air outlet pipe 5, a vacuum pump 51, a discharge pipe 6, a material pump 61, a plate-type solenoid valve 62, and a control console 13. The first support 2 is bolted to the top left of the base 1. The concentration chamber 3 is bolted to the upper part of the first support 2 in a sleeve-like manner. An annular cavity is formed in the inner wall of the concentration chamber. The upper end of this annular cavity is closed, and the lower end is open. The first temperature control plate 31 is bolted to the front of the concentration chamber 3 at a relatively high position. The heating wire 32 is bolted to the inside of the annular cavity and is electrically connected to the first temperature control plate 31. The sealing plate 33 is bolted to the lowest point of the annular cavity, and its bottom end is flush with the bottom end of the annular cavity, thus sealing the annular cavity. The stirring assembly is located inside the concentration chamber 3. The lower end of the feed pipe 4 is welded to the concentration chamber. At the upper left center position of the 3, the sealing plug 41 is attached to the upper end of the feed pipe 4, with its sealing surface tightly against the upper end of the feed pipe wall. The outer periphery of the sealing plug 41 has a semi-circular groove to provide a point of leverage for the operator's hand, facilitating insertion and removal. The left end of the vent pipe 5 is welded to the upper right center position of the concentration chamber 3. The vacuum pump 51 is bolted to the vent pipe 5. The left end of the discharge pipe 6 is welded to the bottom end of the concentration chamber 3. The feed pump 61 is bolted to the right end of the discharge pipe 6. The plate solenoid valve 62 is bolted to the left end of the discharge pipe 6. The lower part of the concentration chamber 3 has a conical structure with a slope that gradually tapers from the side wall to the center, which can concentrate the extract to the discharge pipe 6, helping to improve the discharge efficiency of the extract and reduce extract residue. The control console 13 is bolted to the top left front side of the base 1 and is electrically connected to the vacuum pump 51, the feed pump 61 and the plate solenoid valve 62.
[0020] like Figure 1 and Figure 3 As shown, the drying assembly includes a second support 7, a heating ring 8, a second temperature control plate 81, a drying chamber 9, a discharge pipe 91, a discharge pump 92, and an atomizer 10. The second support 7 is bolted to the top right side of the base 1 and is located to the right of the first support 2. The heating ring 8 is bolted to the upper part of the second support 7. The second temperature control plate 81 is bolted to the front of the heating ring 8 at a relatively high position and is electrically connected to the heating ring 8. The drying chamber 9 is bolted into the annular space of the heating ring 8 in a sleeve-like manner. The discharge pipe 91... The upper end is welded to the bottom of the drying chamber 9. The discharge pump 92 is bolted to the discharge pipe 91 and electrically connected to the control console 13. The drying chamber 9, like the concentration chamber 3, also has a conical structure at the bottom, with an inclined surface that gradually tapers from the side wall to the center. This allows the dried powder to be concentrated and guided to the discharge pipe 91, which helps to improve the powder discharge efficiency and reduce powder residue. The atomizer 10 is bolted to the top of the drying chamber 9 and electrically connected to the control console 13. The right end of the discharge pipe 6 is connected to the atomizer 10.
[0021] like Figure 1 and Figure 2 As shown, the stirring assembly includes a motor 34, a drive gear 35, driven gears 36, a stirring rod 37, and a protective shell 14. The motor 34 is bolted to the top of the concentration chamber 3, with its output shaft facing downwards. The motor 34 is electrically connected to the control console 13. A single drive gear 35 is rotatably mounted at the top of the concentration chamber 3. The output shaft of the motor 34 extends to the center of the drive gear 35, achieving precise power transmission. The three driven gears 36 are arranged in a circle around the output shaft of the motor 34, rotatably mounted at the top of the concentration chamber 3, and evenly distributed around the drive gear 35. The three stirring rods 37 are distributed around the center of the driving gear 35 and are rotatably set inside the concentration chamber 3. The upper end of each stirring rod 37 extends to the outside of the concentration chamber 3 and is fixedly connected to the vertically aligned driven gear 36. The protective shell 14 is welded to the top of the concentration chamber 3 and covers the motor 34, driving gear 35 and driven gear 36. By enclosing the driving gear 35 and driven gear 36 in the protective shell 14, the operator can be prevented from accidentally contacting the high-speed rotating driving gear 35 and driven gear 36, reducing the risk of accidental injury.
[0022] like Figure 1 and Figure 4 As shown, it also includes a limiting rod 11, a receiving box 12, a locking block 111, and a spring 112. The limiting rod 11 is welded to the top right side of the base 1 and located below the drying chamber 9. The receiving box 12 is slidably placed on the top right side of the base 1 and located below the discharge pipe 91, slidingly engaging with the limiting rod 11. This sliding engagement design allows the receiving box 12 to move easily on the limiting rod 11, facilitating the operator to remove or replace the receiving box 12 as needed. Furthermore, the receiving box 12 and the discharge pipe 91 are vertically aligned, ensuring that the powder discharged from the discharge pipe 91 can... The material falls accurately into the receiving box 12. Two locking blocks 111 are arranged side by side and slidably mounted on the limiting rod 11. Two springs 112 are arranged side by side inside the limiting rod 11. The two ends of each spring 112 are fixedly connected to the limiting rod 11 and the corresponding locking block 111, respectively. Two locking holes 121 are arranged side by side at the lower part of the receiving box 12 and are engaged with the two locking blocks 111 one by one. Through the engagement relationship between the locking holes 121 and the locking blocks 111, the receiving box 12 is limited on the limiting rod 11, ensuring that the receiving box 12 is always aligned with the discharge pipe 91.
[0023] When the extract needs to be processed, the operator first starts the vacuum pump 51 through the control panel 13. After the vacuum pump 51 is running, it draws the gas inside the concentration chamber 3 through the left end of the exhaust pipe 5 and discharges the drawn gas through the right end of the exhaust pipe 5, so that the inside of the concentration chamber 3 gradually forms a low-pressure state, which helps the water in the extract to evaporate quickly during the subsequent heating process. After the vacuuming is completed, the vacuum pump 51 is turned off, then the sealing plug 41 is removed, the feed pipe 4 is opened, and then the extract to be concentrated is added into the concentration chamber 3 through the feed pipe 4. During the addition process, attention should be paid to controlling the flow rate and speed to avoid the extract overflowing. After the addition is completed, the sealing plug 41 is closed in time and the feed pipe 4 is closed to ensure the airtightness of the concentration chamber 3.
[0024] Subsequently, the operator activates the heating wire 32 via the first temperature control plate 31 and controls the temperature of the heating wire 32 according to the characteristics of the extract and the concentration requirements. As the heating wire 32 continues to heat up, the internal temperature of the concentration chamber 3 gradually increases, and the water in the extract begins to evaporate, thereby achieving the concentration of the extract. At the same time, the motor 34 is activated, and the output shaft of the motor 34 drives the drive gear 35 to rotate clockwise. The drive gear 35 meshes with three driven gears 36, driving the three driven gears 36 to drive the three stirring rods 37 to rotate counterclockwise. During the rotation, the stirring rods 37 thoroughly stir and mix the extract to ensure that the extract is heated evenly and to avoid local overheating or uneven concentration.
[0025] During the concentration process, the operator starts the heating ring 8 through the second temperature control plate 81 and controls the temperature of the heating ring 8 according to the characteristics of the extract and the requirements of the subsequent drying process. As the heating ring 8 continues to heat up, the temperature inside the drying chamber 9 gradually rises and the preheating operation begins.
[0026] After concentration, the operator turns off the heating wire 32 and the motor 34 to stop the heating and stirring of the extract. Then, the operator controls the plate solenoid valve 62 to open the discharge pipe 6 and starts the pump 61 and atomizer 10. After the pump 61 starts running, it draws the extract from the concentration chamber 3 through the left end of the discharge pipe 6 and sends the drawn extract into the atomizer 10 through the right end of the discharge pipe 6. At this time, the atomizer 10 starts running and uses high-speed airflow to atomize the extract into fine mist and spray it into the drying chamber 9. The sprayed fine mist comes into full contact with the preheated hot air in the drying chamber 9. Under the action of the hot air, the moisture in the extract evaporates rapidly, and the extract gradually dries and becomes powder.
[0027] After drying is completed, the operator turns off the heating ring 8, the material pump 61 and the atomizer 10, and finally starts the discharge pump 92. After the discharge pump 92 is running, it draws the powder inside the drying chamber 9 through the upper end of the discharge pipe 91 and discharges the drawn powder through the lower end of the discharge pipe 91 to the receiving box 12 for centralized collection.
[0028] After collection is completed, the operator turns off the discharge pump 92 and pulls out the receiving box 12 to the right. During the pulling process, the receiving box 12 interacts with the locking block 111 and squeezes the locking block 111 into the limiting rod 11 to disengage from the locking hole 121. At the same time, the locking block 111 compresses the spring 112. After the receiving box 12 is pulled out, the collected powder is poured out. The receiving box 12 is pushed back to the left so that the locking hole 121 is aligned with the locking block 111. The spring 112 returns to its original state and pushes the locking block 111 out from the limiting rod 11 and into the locking hole 121, thus repositioning the receiving box 12 on the limiting rod 11.
