Description

Technical Field

[0001] This invention relates to the field of licorice processing equipment technology, and in particular to an integrated device for licorice emulsification and extract preparation. Background Technology

[0002] Licorice is a traditional Chinese medicinal herb. Its main active ingredients include triterpenoid saponins (glycyrrhizic acid, glycyrrhetinic acid, etc.) and flavonoids (glabridin, isoglycyrrhizin, glycyrrhizin, glycyrrhizin chalcone, etc.). Among them, glycyrrhizin flavonoids have excellent whitening, antioxidant, and anti-inflammatory effects and are widely used in cosmetics and skin care products. However, glycyrrhizin flavonoids are highly lipid-soluble and poorly water-soluble. When directly added to water-based skin care products, they are difficult to dissolve and are prone to precipitation, resulting in low bioavailability. Therefore, the industry usually prepares licorice extract into emulsion systems (such as phospholipid complexes, microemulsions, nanoemulsions, etc.) to improve its water solubility and transdermal absorption efficiency.

[0003] Existing licorice processing equipment suffers from problems such as a large number of devices, large floor space, and high investment costs. Furthermore, the materials need to be transferred multiple times, resulting in significant losses, susceptibility to contamination, long production cycles, and low efficiency. In addition, its filtration efficiency is low, the adsorption of medicinal residues causes significant component loss, and foaming problems are also quite serious.

[0004] Therefore, how to provide an integrated device for licorice emulsification and extract preparation is a problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

[0005] One objective of this invention is to provide an integrated device for licorice emulsification and extract preparation. This invention improves the traditional licorice processing technology by introducing a pre-soaking process and integrating multiple traditional independent devices, which greatly reduces the space occupied by the device and reduces the impact of transfer in different licorice processing steps on licorice extraction.

[0010] Furthermore, a discharge valve is fixedly installed at the bottom of the filter tank, and an inner lining groove is movably installed inside the filter tank. Several drainage holes are opened at the bottom of the inner lining groove. Several guide grooves are fixedly installed at the bottom inside the inner lining groove. The guide grooves are fan-shaped structures with openings on their sides. An extrusion block is movably installed inside the guide groove and is tightly fitted to the inner wall of the guide groove. The extrusion block is a fan-shaped plate structure with the same shape and size as the inside of the guide groove, and its bottom is tightly fitted to the bottom surface inside the inner lining groove. A connecting port is fixedly installed on one side of the top of the guide groove. Several connecting ports on the top of the guide grooves are connected to connecting pipes. An extension pipe is fixedly installed on the top of the connecting pipe and is connected to a pressure controller.

[0011] Furthermore, a top cover is fixedly installed on the top of the pre-impregnation tank, and a stirring motor is fixedly installed on the top of the top cover. The output shaft of the stirring motor extends into the interior of the pre-impregnation tank and a stirring paddle is fixedly installed thereon.

A flow channel is provided inside the pre-impregnation tank, and the flow channel is arranged in a spiral shape inside the pre-impregnation tank. A solenoid valve is fixedly installed at the bottom of the pre-impregnation tank.

[0012] Furthermore, the dual-shaft stirring assembly includes a drive shaft, and the inner wall of the drive shaft is provided with several grooves. The top end of the drive shaft extends into a first cover plate and a second cover plate, and the top end of the drive shaft is provided with a driven wheel.

[0015] The beneficial effects of this invention are: 1. This invention achieves a high degree of integration in its structural design.

[0016] 2. In the filtration process, this invention utilizes the inherent properties of licorice residue. During filtration, the licorice residue is preferentially allowed to settle, and then the residue at the bottom is squeezed to form a self-filtering layer. This achieves high-precision solid-liquid separation and impurity removal. The filter cake layer is naturally stacked from the licorice residue after extraction, and its filtration precision far exceeds that of traditional metal or fiber filters. It can effectively trap fine particles. The filter cake layer also has good adsorption properties, which can further remove various impurities such as colloids, proteins, and pigments from the filtrate, thereby obtaining a clearer and purer filtrate and improving the quality of the final product.

[0017] 3. In terms of process flow, compared with traditional extraction and emulsification equipment, this invention adds parallel operation of the pre-soaking stage and the main extraction stage. Through staggered operation between batches and time optimization, it effectively improves the overall equipment utilization rate and capacity, shortens the production cycle, and improves production efficiency.

[0018] 4. This invention addresses the frequent foaming problem in licorice extraction and emulsification by equipping it with a defoaming device. Combined with a high-efficiency vacuum system, it can quickly respond and defoam under different working conditions, significantly improving the defoaming effect. This completely prevents overflow caused by excessive foam during production and ensures the smooth and continuous operation of the production process. Attached Figure Description

Detailed Implementation

[0029] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the invention, and therefore only show the components relevant to the invention.

[0030] refer to Figure 1 - Figure 10 As shown, an integrated device for licorice emulsification and extract preparation includes a reaction tank 1, with a temperature control tank 102 nested inside the reaction tank 1. The temperature control tank 102 has an inlet pipe and an outlet pipe on its bottom sides, respectively. An anti-corrosion tank 109 is fixedly installed inside the temperature control tank 102, and the bottom of the anti-corrosion tank 109 has a conical structure. A discharge valve 104 is fixedly installed at the bottom of the anti-corrosion tank 109. Support frames 105 are fixedly installed on both sides of the bottom of the reaction tank 1. A first cover plate 101 and a second cover plate 107 are hinged to the top of the reaction tank 1. The reaction tank 1 provides mounting positions for surrounding components and provides an integrated operating space for licorice extraction and emulsification. The temperature control tank 102 is made of insulating material. By connecting a mixing device to the inlet and outlet pipes, the temperature control tank can be... Hot and cold water are injected into the interior of the corrosion-resistant tank 109 to control the internal temperature, thereby providing a stable environment for licorice processing. The corrosion-resistant tank 109 provides a closed processing environment for licorice, ensuring stable processing and avoiding external environmental influences during processing. The conical bottom design guides the extracted mixture to naturally converge downwards, facilitating the material to be discharged through the discharge valve 104 into the filtration stage. The discharge valve 104 controls the flow of material discharge. The support frame 105 provides support and fixation for the entire equipment. The first cover plate 101 and the second cover plate 107 can be opened and closed separately, facilitating the operator's inspection and maintenance of the internal components. The auxiliary materials required for processing can also be added to the corrosion-resistant tank 109 while the pre-soaking process is in parallel. The top of the second cover plate 107 is fixedly installed with a pre-soaking tank 3, and the bottom of the pre-soaking tank 3 extends into the interior of the anti-corrosion tank 109. The pre-soaking tank 3 can pre-soak the next batch of licorice raw materials in advance, so as to realize the pre-soaking process and the extraction and emulsification process of this batch can be carried out in parallel, saving the overall processing time and improving production efficiency. A dual-shaft stirring assembly 4 is installed on the top of the first cover plate 101, and the dual-shaft stirring assembly 4 extends through the first cover plate 101 into the interior of the anti-corrosion tank 109. The dual-shaft stirring assembly 4 can simultaneously achieve two functions: wall scraping and defoaming, and high-speed emulsification and shearing, thereby improving the processing effect. A filter assembly 2 is installed below the reaction vessel 1. The filter assembly 2 can perform solid-liquid separation on the extracted mixture to obtain licorice extract with higher purity, which is convenient for subsequent emulsification treatment. In use, the licorice powder is first added to the pre-soaking tank 3, and the extraction solvent is injected before starting the pre-soaking process. After the previous batch is processed, the solenoid valve at the bottom of the pre-soaking tank 3 is opened to discharge the pre-soaked material into the anti-corrosion tank 109. Then, a new batch of raw materials to be pre-soaked can be added to the pre-soaking tank 3 to start a new round of pre-soaking. At the same time, the extraction process is carried out simultaneously in the anti-corrosion tank 109, realizing parallel processing. During the processing, water at the set temperature is circulated into the temperature control tank 102 through the inlet and outlet pipes to regulate the internal temperature of the anti-corrosion tank 109 to meet the temperature requirements for extraction and emulsification. The second motor 412 is started to drive the drive. The rotating wheel 401 drives the driven wheel 408 and the drive shaft 406 to rotate via the belt 407, which in turn drives the stirring rods 404 on both sides of the drive shaft 406 to rotate. The sides of the stirring rods 404 are in contact with the inner wall of the anti-corrosion tank 109, which can not only scrape off the material adhering to the inner wall, but also cut and crush the foam generated during the processing with the defoaming teeth. In conjunction with the vacuum pump 106 to extract the gas inside the anti-corrosion tank 109 to form a negative pressure, the foam can be further eliminated to prevent overflow. The inclined surface of the groove inside the stirring rod 404 can guide the foam to collect into the groove, improving the foam crushing efficiency of the defoaming teeth. After extraction, the first motor... 410 is energized and rotates, causing the emulsifying shaft 409 to rotate at high speed inside the drive shaft 406. The screw rod 403 guides the liquid material inside the corrosion-resistant tank 109 through the inlet 402 into the drive shaft 406. Under the pressure applied by the screw rod 403, the liquid material entering the drive shaft 406 is forced between the drive shaft 406 and the emulsifying shaft 409 for high-speed shearing emulsification. The emulsified liquid material is then discharged from the outlet 405 of the drive shaft 406 back into the corrosion-resistant tank 109 to complete emulsification. After the licorice extraction and emulsification are complete, the discharge valve 104 is opened, discharging the mixture into the inner lining tank 207 of the filter assembly 2. Inside, the liquid carrying residue settles in the liner tank 207. After the residue has settled, a high-pressure medium is introduced into the guide tank 206, pushing each extrusion block 205 to slide along the guide tank 206 and extruding the licorice residue settled at the bottom. This causes the residue to be tightly stacked to form a residue self-filtering layer, further squeezing out the extract adsorbed inside the residue. Then, the valve at the bottom of the filter tank 201 is opened to discharge the filtered liquid. At the same time, the residue self-filtering layer can trap fine impurities and improve the purity of the filtrate. The residue after filtration remains inside the filter tank 201. The residue can be discharged by lifting out the liner tank 207, completing the entire preparation process.

[0031] refer to Figure 1 - Figure 3As shown, the temperature control tank 102 has a serpentine flow channel inside, with its two ends connected to an inlet pipe and an outlet pipe, respectively. Valves are fixedly installed on both the inlet and outlet pipes, and a mixing device is connected externally to both. The corrosion-resistant tank 109 has a level gauge, a temperature sensor, and a pressure sensor fixedly installed inside. A main controller is fixedly installed on the side of the reaction tank 1, and the main controller is electrically connected to other electronic components via cables. The main controller is a 6ES7215-1AG40-0XB0 model, and the level gauge is an FMR50 model. The level gauge can monitor the liquid level inside the corrosion-resistant tank 109 in real time. The temperature sensor adopts the TM411 type, which can accurately detect the actual temperature inside the tank, so that the main controller can adjust the inlet water temperature of the temperature-controlled tank 102 according to the processing requirements. The air pressure sensor adopts the SA-11 type, which can monitor the air pressure inside the tank in real time and adjust the negative pressure in time with the vacuum pump 106 to meet the air pressure requirements of different processing stages. The main controller can uniformly control the operation of various electronic components, making the processing flow of the equipment more precise and controllable, and realizing automated processing operation.

[0032] refer to Figure 1 - Figure 3 As shown, a ladder 103 is welded to the side of the reaction vessel 1. A vacuum pump 106 is fixedly installed on the top of the first cover plate 101, and the suction end of the vacuum pump 106 extends into the interior of the corrosion-resistant tank 109. A base 108 is fixedly installed at the bottom of the support frame 105. The base 108 can increase the contact area between the support frame 105 and the ground, improve the overall stability of the equipment, and prevent shaking and displacement during operation. The ladder 103 allows operators to climb to the top of the equipment to install and maintain the components above the first cover plate 101 and the second cover plate 107. The vacuum pump 106 is a 2BVA-2060 type. The vacuum pump 106 can stably extract the gas inside the corrosion-resistant tank 109 to form a negative pressure environment required for processing inside the tank. This can not only help eliminate foam in conjunction with defoaming operations, but also meet the process requirements of negative pressure extraction, thereby improving the extraction efficiency of licorice active ingredients.

[0033] refer to Figure 8 - Figure 10 As shown, the filter assembly 2 includes a filter tank 201. Four connecting brackets 202 are provided on the side of the filter tank 201, and the connecting brackets 202 are connected to the support frame 105. A pressure controller 209 is fixedly installed on the side of the filter tank 201. The filter tank 201 can be connected to the support frame 105 through the connecting brackets 202, thereby fixing the filter assembly 2 as a whole. The pressure controller 209 can be connected to the connecting pipe 203 and the inside of the guide groove 206 through the extension pipe 204, thereby controlling the movement state of the extrusion block 205 inside the guide groove 206 by injecting or extracting pressure medium inside the guide groove 206.

[0034] refer to Figure 8- Figure 10 As shown, a discharge valve is fixedly installed at the bottom of the filter tank 201, and an inner lining groove 207 is movably installed inside the filter tank 201. Several drainage holes 208 are opened at the bottom of the inner lining groove 207. Several guide grooves 206 are fixedly installed at the bottom inside the inner lining groove 207. The guide grooves 206 have a fan-shaped structure and openings on their sides. An extrusion block 205 is movably installed inside the guide groove 206, and the extrusion block 205 is tightly fitted to the inner wall of the guide groove 206. The extrusion block 205 is a fan-shaped plate structure with the same shape and size as the inside of the guide groove 206, and the bottom of the extrusion block 205 is tightly fitted to the bottom surface of the inner lining groove 207. A connecting port is fixedly installed on one side of the top of the guide groove 206. Several connecting ports on the top of the guide grooves 206 are connected to connecting pipes 203. An extension pipe 204 is fixedly installed on the top of the connecting pipe 203, and the extension pipe 204 is connected to the pressure controller 209. The discharge valve can control the bottom of the filter tank 201. The switch of the inner liner 207 facilitates the discharge of the filtered liquid. The inner liner 207 supports the material discharged from the corrosion-resistant tank 109 and uses internal components to separate the solid and liquid components. The drain hole 208 allows the liquid to pass through, while the solid residue is filtered and retained in the inner liner 207. The guide groove 206 provides a moving guide for the extrusion block 205, ensuring that the extrusion block 205 slides stably without deviating. When the pressure controller 209 injects pressure medium into the guide groove 206, it can push the extrusion block 205 to slide along the guide groove 206 towards the center, extruding the licorice residue that has settled at the bottom. This compacts the residue into a dense filtration layer, which can squeeze out the residual extract and form a more precise filtration layer to trap impurities. After filtration is completed, the pressure controller 209 removes the pressure medium from the guide groove 206, which can drive the extrusion block 205 back to its original position along the guide groove 206, making it easy to remove the residue and complete the slag discharge.

[0035] refer to Figure 1 - Figure 3As shown, a top cover 301 is fixedly installed on the top of the pre-soaking tank 3, and a stirring motor 302 is fixedly installed on the top of the top cover 301. The output shaft of the stirring motor 302 extends into the interior of the pre-soaking tank 3 and a stirring paddle is fixedly installed thereon. Two water pipes are fixedly installed on one side of the top of the pre-soaking tank 3, and a water mixer is connected to the outside of the water pipes. A flow channel is provided inside the pre-soaking tank 3, and the flow channel is arranged in a spiral shape inside the pre-soaking tank 3. A solenoid valve is fixedly installed at the bottom of the pre-soaking tank 3. The top cover 301 provides a position for the stirring motor 302 to be installed. The stirring motor 302 is a VFD007E43A type. After the stirring motor 302 is powered on, it can rotate, thereby driving the stirring paddle inside the pre-soaking tank 3 to rotate at a uniform speed, thereby improving the pre-soaking effect of licorice inside the pre-soaking tank 3 according to processing needs. The pre-soaking tank 3 is connected to the outside of the water pipes by a water mixer, which can inject appropriate warm water into the pre-soaking tank 3, thereby providing a stable environment for the pre-soaking treatment of licorice.

[0036] refer to Figure 4 - Figure 7As shown, the dual-shaft stirring assembly 4 includes a drive shaft 406, and several grooves are formed on the inner wall of the drive shaft 406. A first cover plate 101 and a second cover plate 107 extend from the top of the drive shaft 406, and a driven wheel 408 is provided at the top of the drive shaft 406. An outlet 405 and an inlet 402 are formed on the front of the drive shaft 406, and the outlet 405 is located above the inlet 402. The drive shaft 406 has a hollow tubular structure, and stirring rods 404 are welded to both sides of the drive shaft 406. The stirring rods 404 have a trapezoidal frame structure, and the sides of the stirring rods 404 are in contact with the inner wall of the anti-corrosion tank 109. Several defoaming teeth are provided at the contact points on the inner wall of tank 109, and the top surface of the groove inside the stirring rod 404 is an inclined surface that gradually increases from top to bottom. The inclined surface can guide the foam generated during processing to collect into the groove of the stirring rod 404, so that the foam can fully contact the defoaming teeth and improve the efficiency of foam breaking. The stirring rod 404, which is in close contact with the inner wall of the anti-corrosion tank 109, can also scrape off the material adhering to the inner wall, avoiding the material from adhering to the inner wall for a long time and causing uneven heating, which affects the extraction effect. This ensures that all materials can participate in the stirring and extraction process. An emulsifying shaft 409 is movably installed inside the drive shaft 406, and a spiral rod 4 is welded to the surface of the emulsifying shaft 409. 03, and the outer edge of the spiral rod 403 is in contact with the inner wall of the drive shaft 406. The top end of the emulsifying shaft 409 extends out of the drive shaft 406, and the top end of the emulsifying shaft 409 is connected to the first motor 410 through a coupling. The first motor 410 is fixedly mounted on the lifting seat 411, which is mounted on the top of the first cover plate 101. The top of the first cover plate 101 is fixedly mounted with a second motor 412. The output end of the second motor 412 is equipped with a drive wheel 401. The drive wheel 401 and the driven wheel 408 are connected by a belt 407. During the extraction stage, only the drive shaft 406 needs to drive the stirring rod 404 to rotate to complete the stirring and scraping. For wall defoaming, high-speed emulsification is not required. After extraction, the first motor 410 starts and drives the emulsification shaft 409 to rotate at high speed inside the drive shaft 406. As the emulsification shaft 409 rotates, the screw rod 403 can draw the liquid outside the drive shaft 406 from the inlet 402 into the drive shaft 406. Then, the screw rod 403 pushes the liquid into the groove on the inner wall of the drive shaft 406 between the emulsification shaft 409 and the emulsification shaft. The liquid is subjected to strong shearing and squeezing in the gap of high-speed relative rotation to complete the emulsification process. Finally, the emulsified liquid is discharged from the outlet 405 and returned to the corrosion protection tank 109. Repeating this process multiple times can complete the uniform emulsification operation.

[0037] refer to Figure 4 - Figure 7As shown, a belt 407 is fitted around the outer side of the driven wheel 408, and a drive wheel 401 is fitted around the inner side of the belt 407. The drive wheel 401 is rotatably connected to the first cover plate 101. A second motor 412 is fixedly connected to the top of the drive wheel 401, and the second motor 412 is fixedly connected to the first cover plate 101 through a motor frame. The second motor 412 is an MD380T3.7GB type. The second motor 412 can stably output torque, driving the drive wheel 401 to rotate at a uniform speed, and then transmitting torque through the belt 407 to drive the drive wheel 401 to rotate at a uniform speed. The driven wheel 408 rotates to provide stable rotational power to the drive shaft 406 and the stirring rod 404, ensuring continuous and stable operation of the stirring and scraping operation. The lifting seat 411 can adjust the overall installation height of the first motor 410 and the emulsifying shaft 409, making it convenient to adjust the position of the emulsifying shaft 409 within the drive shaft 406 during installation and maintenance, ensuring transmission matching accuracy. It also facilitates disassembly and maintenance of internal components. During the emulsification process, the emulsification effect of the emulsifying shaft 409 and the drive shaft 406 can be adjusted by adjusting the longitudinal position of the emulsifying shaft 409.

[0038] refer to Figure 4 - Figure 7 As shown, an emulsifying shaft 409 is movably installed inside the drive shaft 406, and the emulsifying shaft 409 is tightly fitted to the inner wall of the drive shaft 406. A first motor 410 is installed on the top of the drive shaft 406, and the first motor 410 is connected to the first cover plate 101 through a lifting seat 411. The bottom end of the emulsifying shaft 409 is a spiral rod 403, and the position of the spiral rod 403 matches the position of the water inlet 402. The first motor 410 is an MD380T7.5GB type. The spiral rod 403 can rotate synchronously at high speed with the emulsifying shaft 409, stably guiding the liquid material in the anti-corrosion tank 109 from the water inlet 402 into the drive shaft 406, ensuring that the liquid can continuously enter the emulsification shear gap, maintaining the continuous emulsification operation, and preventing the problem of interruption of material supply affecting the emulsification uniformity.

[0039] Working principle: After the equipment is assembled, the processing parameters are preset through the main controller before use. First, the licorice powder raw material is added into the pre-soaking tank 3. After the extraction solvent is injected, the stirring motor 302 is controlled to drive the stirring paddle to rotate to complete the pre-soaking treatment according to the actual production needs. At the same time, temperature-controlled water is introduced into the spiral flow channel of the pre-soaking tank 3 to ensure the stability of the pre-soaking temperature. After pre-impregnation is completed, the solenoid valve at the bottom of the pre-impregnation tank 3 is opened to discharge the material into the corrosion-resistant tank 109. Then, a new batch of raw materials to be pre-impregnated can be added to the pre-impregnation tank 3 to begin a new round of pre-impregnation. Simultaneously, extraction and processing are carried out in the corrosion-resistant tank 109, achieving parallel processing. During processing, water at a set temperature is circulated through the inlet and outlet pipes of the temperature-controlled tank 102 to regulate the internal temperature of the corrosion-resistant tank 109, meeting the temperature requirements for extraction and emulsification. The second motor 412 starts, driving the drive wheel 401 to rotate, which in turn drives the driven wheel via the belt 407. The rotation of wheel 408 and drive shaft 406 drives the rotation of stirring rods 404 on both sides of drive shaft 406. The sides of stirring rods 404 are attached to the inner wall of anti-corrosion tank 109 to scrape off the material adhering to the inner wall. The defoaming teeth cut and crush the foam generated during the processing. The inclined surface of the groove inside stirring rod 404 guides the foam to collect into the groove, improving the defoaming efficiency of the defoaming teeth. At the same time, vacuum pump 106 draws gas from inside anti-corrosion tank 109 to form negative pressure, further eliminating foam and preventing overflow. It can also meet the process requirements of negative pressure extraction and improve extraction efficiency. After extraction, the first motor 410 is energized and rotates to drive the emulsifying shaft 409 to rotate at high speed inside the drive shaft 406. The screw rod 403 guides the liquid material inside the corrosion-resistant tank 109 into the drive shaft 406 through the inlet 402. Under the pressure applied by the screw rod 403, the liquid material entering the drive shaft 406 is squeezed into the groove between the drive shaft 406 and the emulsifying shaft 409 for high-speed shear emulsification. The liquid material that has undergone high-speed shear emulsification is then discharged from the outlet 405 of the drive shaft 406 and returned to the corrosion-resistant tank 109. The emulsification operation is completed by repeating this cycle multiple times. After the licorice has been extracted and emulsified, the discharge valve 104 is opened to discharge the mixture into the inner lining tank 207 of the filter assembly 2, allowing the liquid carrying the residue to settle in the inner lining tank 207. After the residue has settled, the pressure controller 209 introduces a high-pressure medium into the guide tank 206, pushing each extrusion block 205 to slide along the guide tank 206, extruding the licorice residue settled at the bottom, making the residue tightly stacked, forming a residue self-filtering layer above several drainage holes 208, further squeezing out the extract adsorbed inside the residue. Then, the discharge valve at the bottom of the filter tank 201 is opened to discharge the filtered liquid. At the same time, the residue self-filtering layer traps fine impurities, improving the purity of the filtrate. The filtered residue remains inside the filter tank 201. The residue can be discharged by lifting out the inner lining tank 207, completing the entire preparation process.
