Description

Technical Field

[0001] This invention relates to the field of raw material crushing technology for Japanese raisin tree (Hovenia dulcis), specifically to a raw material crushing device and process based on the extraction of ultrafine powder from Japanese raisin tree. Background Technology

[0002] The raw material pulverizing device for the extraction of Hovenia dulcis (jujube) ultrafine powder is the core pretreatment equipment for achieving subsequent efficient extraction. Its working principle is based on high-temperature drying, pulverizing and sieving. Through the optimization of refined raw material pretreatment, multi-stage pulverization process, precise sieving system and coordinated supporting auxiliary system, a closed-loop control of the whole process is formed to ensure that the final ultrafine powder meets the requirements of particle size uniformity, component integrity and extraction adaptability.

[0003] Traditional crushing methods cause the jujubes to stick to the inside of the crushing equipment. As the crushing time increases, high temperatures are generated, resulting in a charred state that cannot be completely crushed. Due to the high sugar content, the ultrafine powder will also stick to the filter screen, leading to low ultrafine powder efficiency, low powder output, a strong charred taste, and the need for constant cleaning.

[0004] To address the aforementioned issues, there is an urgent need for innovative design of raw material pulverizing devices and processes based on the extraction of jujube ultrafine powder. Summary of the Invention

[0005] The present invention addresses the problem of overly simplistic solutions in existing technologies by providing a significantly different approach. Specifically, the present invention aims to provide a raw material pulverizing device and process based on the extraction of jujube ultrafine powder, thereby solving the aforementioned problems raised in the background section.

[0008] Preferably, the movable frame has a cavity that slides with the fixed rod, the outer wall of the movable frame is slidably connected to a base, the base is fixedly connected to the crushing barrel, and the base has a cavity that slides with the movable frame.

[0009] Preferably, the fixed column has a cavity that cooperates with the sliding of the lifting column. A spring is installed in the cavity, one end of the spring is fixedly connected to the inner wall of the cavity of the lifting column, and the other end of the spring is fixedly connected to the top of the lifting column.

[0010] Preferably, the cleaning assembly includes a rack fixed to one side of the movable frame, a gear meshing at the top of the rack, a disk fixedly connected to the gear via a connecting shaft, connecting plates fixed to both sides of the disk, and one side of the connecting plate fixedly connected to a scraper.

[0011] Preferably, the guiding assembly includes a lifting frame fixedly connected to an electric push rod. A limit plate is fixed to the inner wall of the conveying lifting frame. The limit plate has symmetrically opened sliding grooves. A first connecting post is slidably connected in one of the sliding grooves. A rotating disk is fixed to one end of the first connecting post. A fixed shaft is fixed to one end of the rotating disk. The outer wall of the fixed shaft is fixedly connected to the first guide plate. A second connecting post is slidably connected in the other sliding groove. A rotating ring is fixed to one end of the second connecting post. A sleeve is fixed to the inner wall of the rotating ring. A second guide plate is fixed to the outer wall of the sleeve.

[0012] Preferably, a sleeve is fitted onto the outer wall of the fixed shaft, the rotating ring is fitted onto the outer wall of the fixed shaft, and the limiting plate has a cavity that moves in conjunction with the sleeve.

[0013] Preferably, a lifting frame is fixed at the top of the lifting frame, and the conveying channel has a cavity that moves in conjunction with the lifting frame. A connecting ring is slidably connected to the top of the lifting frame, and the connecting ring is rotatably limited to the conveying channel. The inner wall of the connecting ring is fixedly connected to an elastic rope.

[0014] Preferably, the bottom end of the connecting ring is provided with a guide groove, the guide groove is slidably connected to the lifting frame, and the contact surface between the guide groove and the lifting frame is an inclined surface.

[0015] A raw material pulverization process based on the extraction of Hovenia dulcis ultrafine powder includes the following steps:

[0016] S1: Initial preparation: Based on the characteristics of the material to be crushed, the Japanese jujube is treated in a targeted manner to avoid blockage, adhesion or insufficient crushing during the crushing process. The processed Japanese jujube is put into the crushing barrel through the feeding port that is fixedly connected to the conveying channel.

[0017] S2: Start the equipment: First, turn on the main motor of the main body and crush the jujubes with the vibrating rod. After the vibration is stable, turn on the matching cooling mechanism and monitor the temperature inside the barrel in real time through the temperature measuring point on the outer wall of the crushing barrel or the infrared thermometer.

[0018] S3: Enhanced crushing effect and inner wall cleaning: The motor drives the rotating parts to rotate, which in turn drives the moving frame to drive the crushing roller to crush the jujube along the arc surface inside the crushing barrel, preventing the formation of uncrushed particles. At the same time, the moving frame drives the scraper to rotate, scraping off the jujube powder adhering to the inner wall of the crushing barrel.

[0019] S4: Screening and conveying process: The main motor is turned off, and the lifting frame is moved by the electric push rod, which in turn drives the connecting ring to rotate, increasing the gap between the elastic ropes. This allows the crushed jujube powder to pass through the conveying channel. The movement of the lifting frame drives the first guide plate and the second guide plate to rotate. The jujube powder passing through the elastic ropes falls onto the surface of the first guide plate and the second guide plate, and then slides into the storage box.

[0020] S5: Shutdown and Discharge: Turn off the main motor and wait for the equipment to completely stop vibrating before opening the discharge valve of the crushing barrel. The crushed mixed powder is then fed into the grading device or temporary storage tank by gravity.

[0021] Compared with the prior art, the beneficial effects of the present invention are:

[0022] 1. This invention uses a rotating component to drive a fixed rod to rotate. Because the moving frame has a cavity that slides with the fixed rod, it moves horizontally. As the moving frame moves, it causes the moving frame to slide within the base, which in turn causes the fixed column and lifting column, fixed at the bottom of the moving frame, to move along the arc surface of the crushing barrel. A spring is installed between the fixed column and the lifting column. When the fixed column and the lifting column move along the arc surface, the lifting column can adaptively extend and retract, ensuring that the crushing roller can fit against different areas such as the inner wall of the crushing barrel and the gaps between media. This effectively crushes uncrushed particles, such as fine jujube particles stuck in the gaps between the vibrating rods, compensating for the blind spots of simple vibrating rod crushing and significantly enhancing the uniformity of crushing. This not only makes the nutrients more easily absorbed by the human body, effectively improving product quality, but also makes the crushed jujube more space-efficient, requiring less space and facilitating storage and transportation. Furthermore, the powdered form makes it less prone to spoilage, extending the product's shelf life.

[0023] 2. This invention activates an electric push rod to move the lifting frame. Through the movement of the lifting frame, lifting frame, guide groove, connecting ring, and elastic rope, the elastic rope is stretched to adjust the spacing. The spacing can be flexibly controlled according to the degree of pulverization, which can screen powders of different coarseness and avoid the problem of easy clogging of traditional fixed screens. When the lifting frame moves, it simultaneously drives the limiting plate. Through the transmission of the limiting plate, the first connecting column, the second connecting column, the rotating disk, the rotating ring, the fixed shaft, and the sleeve, the tilt angle of the first guide plate and the second guide plate is adjusted. By changing the cross-sectional area of ​​the channel and guiding the airflow direction, the material conveying speed is precisely controlled, avoiding impact wear caused by excessive speed or sedimentation caused by excessive speed. Furthermore, through the collision and turbulence between the guide plate and the particles, the agglomerated particles are broken up, avoiding the problem of airflow dead zone clogging in traditional straight cylinder channels.

[0024] 3. In this invention, the moving frame drives the rack to move synchronously, and the moving rack drives the meshing gear to rotate. The gear is fixedly connected to the disc through a connecting shaft. The rotation of the gear drives the disc to rotate synchronously, and the disc is fixedly connected to the scraper through a connecting plate. When the disc rotates, the connecting plate drives the scraper to scrape the inner wall of the crushing barrel, preventing the jujube powder from forming an adhesive layer on the barrel wall due to static electricity and molecular attraction. This prevents the adhesive layer from falling off and mixing into the material to form lumpy impurities, ensuring the uniform particle size of the ultrafine powder and providing a quality foundation for the integrity of the components in the subsequent extraction process.

[0036] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0037] Please see Figures 1 to 10 This invention provides a technical solution: a raw material pulverizing device based on the extraction of jujube ultrafine powder, comprising a main body 1, a pulverizing barrel 2 inside the main body 1, a cooling mechanism 3 fixed on one side of the pulverizing barrel 2, and multiple vibrating rods 14 placed inside the pulverizing barrel 2, a pulverizing roller 5 inside the pulverizing barrel 2, a pulverizing component on one side of the pulverizing roller 5, and the pulverizing component driving the pulverizing roller 5 to crush the raw material at the bottom of the pulverizing barrel 2, scrapers 7 symmetrically arranged on the inner wall of the pulverizing barrel 2, a cleaning component on one side of the scraper 7, and the cleaning component driving the scraper 7 to remove the adhesive on the inner wall of the pulverizing barrel 2, a conveying channel 8 fixed at the bottom of the pulverizing barrel 2, multiple elastic ropes 13 equidistantly and crosswise arranged inside the conveying channel 8, an adjusting component outside the elastic ropes 13, and the adjusting component adjusting the distance between adjacent elastic ropes 13, a first guide plate 10 and a second guide plate 11 at the bottom of the elastic ropes 13, a guiding component on one side of the first guide plate 10 and the second guide plate 11, and the guiding component adjusting the tilt angle of the first guide plate 10 and the second guide plate 11.

[0038] In specific implementation, when the crushing barrel 2 inside the main body 1 is crushed by the vibrating rod 14, the cooling mechanism 3 works simultaneously (the cooling mechanism 3 is cooled by an external cold air conveying device and pipeline through a jacketed air supply). The cooling mechanism 3 cools the inside to prevent gelatinization. At the same time, the crushing component drives the crushing roller 5 to crush the raw material at the bottom of the crushing barrel 2 to enhance the crushing effect. The cleaning component drives the scraper 7 to remove the sticky material on the inner wall of the crushing barrel 2. The crushed powder is output through the bottom conveying channel 8. During this process, the adjusting component adjusts the spacing of the elastic rope 13 to screen powders of different coarseness. The guiding component adjusts the tilt angle of the first guide plate 10 and the second guide plate 11 to ensure smooth material conveying.

[0039] As a further embodiment of the present invention, the crushing assembly includes a rotating component 401 fixedly connected to the output end of the motor, a fixed rod 402 fixedly fixed on one side of the rotating component 401, a movable frame 403 slidably connected to the outer wall of the fixed rod 402, a movable frame 404 fixedly fixed on one side of the movable frame 403, fixed columns 406 symmetrically fixed at the bottom end of the movable frame 404, a lifting column 408 slidably connected inside the fixed column 406, and a side of the lifting column 408 fixedly connected to the crushing roller 5.

[0040] In practice, the motor drives the rotating part 401 to rotate, causing the fixed rod 402 fixed on one side of the rotating part 401 to rotate synchronously. Since the fixed rod 402 is slidably connected to the moving frame 403, it drives the moving frame 403 and the moving frame 404 fixed thereto to move. The fixed column 406 at the bottom of the moving frame 404 and the slidingly connected lifting column 408 move accordingly, ultimately driving the crushing roller 5 on one side of the lifting column 408 to perform the crushing action.

[0041] As a further embodiment of the present invention, the movable frame 403 has a cavity that slides with the fixed rod 402, and the outer wall of the movable frame 404 is slidably connected to the base 405. The base 405 is fixedly connected to the crushing barrel 2, and the base 405 has a cavity that slides with the movable frame 404.

[0042] In practice, the movable frame 403 slides with the fixed rod 402 through its own cavity, ensuring that the fixed rod 402 can stably drive the movable frame 403 to move horizontally when it rotates. At the same time, the movable frame 404, which is fixed to the movable frame 403, slides through the cavity on the base 405, providing guidance and support for the movement of the movable frame 404, ensuring that it drives the subsequent components to move stably to complete the crushing operation.

[0043] As a further embodiment of the present invention, the fixed column 406 has a cavity that cooperates with the sliding of the lifting column 408. A spring 407 is provided in the cavity. One end of the spring 407 is fixedly connected to the inner wall of the cavity of the lifting column 408, and the other end of the spring 407 is fixedly connected to the top end of the lifting column 408.

[0044] In practice, when the crushing component drives the crushing roller 5 to work, the fixed column 406 provides sliding space for the lifting column 408 through its own cavity. One end of the spring 407 in the cavity is fixed to the inner wall of the cavity of the fixed column 406, and the other end is fixed to the top of the lifting column 408. When the lifting column 408 moves along the arc surface of the crushing barrel 2 with the moving frame 404, the spring 407 can adaptively extend and retract to ensure that the lifting column 408 can drive the crushing roller 5 to fit into different areas and achieve stable crushing.

[0045] As a further embodiment of the present invention, the cleaning component includes a rack 601 fixed to one side of the movable frame 404, a gear 602 meshing at the top of the rack 601, a disc 603 fixedly connected to the gear 602 via a connecting shaft, and connecting plates 604 fixed on both sides of the disc 603, with one side of the connecting plate 604 fixedly connected to the scraper 7.

[0046] In practice, when the moving frame 404 moves, it drives the rack 601 fixed on one side to move synchronously. The rack 601 meshes with the gear 602 at the top, causing the gear 602 to drive the disc 603 to rotate through the connecting shaft. The connecting plates 604 on both sides of the disc 603 move in tandem, thereby driving the scraper 7 fixed to the connecting plate 604 to clean the inner wall of the crushing barrel 2.

[0047] As a further embodiment of the present invention, the guide assembly includes a lifting frame 901 fixedly connected to an electric push rod. A limit plate 902 is fixedly fixed to the inner wall of the conveying lifting frame 901. The limit plate 902 is symmetrically provided with sliding grooves 903. A first connecting post 905 is slidably connected in one of the sliding grooves 903. A rotating disk 904 is fixed to one end of the first connecting post 905. A fixed shaft 906 is fixed to one end of the rotating disk 904. The outer wall of the fixed shaft 906 is fixedly connected to the first guide plate 10. A second connecting post 908 is slidably connected in the other sliding groove 903. A rotating ring 907 is fixed to one end of the second connecting post 908. A sleeve 909 is fixed to the inner wall of the rotating ring 907. A second guide plate 11 is fixed to the outer wall of the sleeve 909.

[0048] In practice, the electric push rod drives the lifting frame 901 to move, causing the limiting plate 902 fixed on the inner wall of the lifting frame 901 to move synchronously. In the sliding groove 903 symmetrically opened in the limiting plate 902, the first connecting column 905 and the second connecting column 908 slide respectively, thereby driving the first connecting column 905 to drive the rotating disk 904 and the fixed shaft 906 to rotate, causing the first guide plate 10 on the outer wall of the fixed shaft 906 to adjust its angle. At the same time, the second connecting column 908 drives the rotating ring 907 and the sleeve 909 to rotate, causing the second guide plate 11 on the outer wall of the sleeve 909 to adjust its angle.

[0049] As a further embodiment of the present invention, a sleeve 909 is sleeved on the outer wall of the fixed shaft 906, a rotating ring 907 is sleeved on the outer wall of the fixed shaft 906, and a limiting plate 902 has a cavity that moves in coordination with the sleeve 909.

[0050] In practice, the sleeve 909 fitted on the outer wall of the fixed shaft 906 cooperates with the rotating ring 907 also fitted on the outer wall of the fixed shaft 906. At the same time, the limiting plate 902 provides the sleeve 909 with the space for movement through its own cavity, ensuring that the rotating ring 907 drives the sleeve 909 to rotate stably as the second connecting column 908 slides, thereby ensuring that the second guide plate 11 can smoothly complete the tilt angle adjustment.

[0051] As a further embodiment of the present invention, a lifting frame 121 is fixed at the top of the lifting frame 901, and the conveying channel 8 is provided with a cavity that moves in coordination with the lifting frame 121. A connecting ring 123 is slidably connected to the top of the lifting frame 121. The connecting ring 123 is rotatably limited to the conveying channel 8, and the inner wall of the connecting ring 123 is fixedly connected to the elastic rope 13.

[0052] In practice, the lifting frame 121 at the top of the lifting frame 901 can move within the cavity opened in the conveying channel 8. The top of the lifting frame 121 is slidably connected to the connecting ring 123, and the connecting ring 123 is rotatably limited connected to the conveying channel 8. Its inner wall is fixed to the elastic rope 13. When the lifting frame 901 moves the lifting frame 121, it can cause the connecting ring 123 to rotate, thereby adjusting the elastic rope 13.

[0053] As a further embodiment of the present invention, a guide groove 122 is provided at the bottom end of the connecting ring 123. The guide groove 122 is slidably connected to the lifting frame 121, and the contact surface between the guide groove 122 and the lifting frame 121 is an inclined surface.

[0054] In specific implementation, the guide groove 122 at the bottom of the connecting ring 123 is slidably connected to the lifting frame 121, and the contact surface between the two is inclined. When the lifting frame 901 drives the lifting frame 121 to move, the lifting frame 121 slides along the inclined surface of the guide groove 122, and the inclined surface transmission is converted into the rotation of the connecting ring 123, which in turn drives the elastic rope 13 fixed on the inner wall of the connecting ring 123 to adjust the spacing.

[0055] A raw material pulverization process based on the extraction of Hovenia dulcis ultrafine powder includes the following steps:

[0056] S1: Initial preparation: Based on the characteristics of the material to be crushed, the jujube is treated in a targeted manner to avoid blockage, adhesion or insufficient crushing during the crushing process. The processed jujube is then put into the crushing barrel 2 through the feeding port that is fixedly connected to the conveying channel 8.

[0057] S2: Start the equipment: First, turn on the main motor of the main body 1 and crush the jujubes through the vibrating rod 14. After the vibration is stable, turn on the matching cooling mechanism 3 and monitor the temperature inside the barrel in real time through the temperature measuring point on the outer wall of the crushing barrel 2 or the infrared thermometer.

[0058] S3: Enhance the crushing effect and clean the inner wall: The motor drives the rotating part 401 to rotate, which in turn drives the moving frame 403 to drive the crushing roller 5 to crush the jujube along the arc surface in the crushing barrel 2, preventing the formation of uncrushed particles. At the same time, the moving frame 403 drives the scraper 7 to rotate, scraping off the jujube powder adhering to the inner wall of the crushing barrel 2.

[0059] S4: Screening and conveying process: The main motor is turned off, and the lifting frame 901 is moved by the electric push rod, which in turn drives the connecting ring 123 to rotate, thereby increasing the gap between the elastic ropes 13. This allows the crushed jujube powder to pass through the conveying channel 8. The movement of the lifting frame 901 drives the first guide plate 10 and the second guide plate 11 to rotate. The jujube powder passing through the elastic ropes 13 falls onto the surface of the first guide plate 10 and the second guide plate 11, and then slides into the storage box.

[0060] S5: Shutdown and Discharge: Turn off the main motor and wait for the equipment to stop vibrating completely. Then, open the discharge valve of the crushing tank 2 and discharge the crushed mixed powder by gravity into the grading device or temporary storage tank.

[0061] Working principle: When using the raw material pulverizing device based on the extraction of jujube ultrafine powder, open the opening and closing door of the main body 1, rotate the pulverizing barrel 2, put the jujube into the pulverizing barrel 2 through the storage box fixedly connected to the conveying channel 8, rotate the pulverizing barrel 2 again, fix the position when the conveying channel 8 is at the top of the pulverizing barrel 2, start the vibration motor of the main body 1, drive the multiple vibrating rods 14 in the pulverizing barrel 2 to pulverize the jujube, and at the same time start the cooling mechanism 3. The low temperature closed pulverizing chamber vibration impact mill fully crushes the jujube and directly forms ultrafine powder.

[0062] At the same time, the motor is started, which drives the rotating part 401 to rotate. The rotation of the rotating part 401 also drives the fixed rod 402 fixedly connected to one side to rotate. Since the moving frame 403 has a cavity that slides with the fixed rod 402, the moving frame 403 moves horizontally. When the moving frame 403 moves, it drives the moving frame 404 fixed on one side to slide in the base 405. This causes the fixed column 406 and the lifting column 408 fixed at the bottom of the moving frame 404 to move along the arc surface in the crushing barrel 2. A spring 407 is provided between the fixed column 406 and the lifting column 408. When the fixed column 406 and the lifting column 408 move along the arc surface, the lifting column 408 can extend and retract adaptively, so as to drive the crushing roller 5 to move along the arc surface and crush the uncrushed particles of jujube, thus enhancing the crushing effect.

[0063] When the moving frame 404 moves, it drives the rack 601 fixed on one side to move synchronously. When the rack 601 moves, it drives the gear 602 meshing on one side to rotate. The gear 602 is fixedly connected to the disc 603 through the connecting shaft. The rotation of the gear 602 drives the disc 603 to rotate synchronously. The disc 603 is fixedly connected to the scraper 7 through the connecting plate 604. When the disc 603 rotates, the connecting plate 604 drives the scraper 7 to scrape the inner wall of the crushing barrel 2 to prevent the jujube powder from sticking to the inner wall.

[0064] After crushing is complete, rotate the crushing drum 2 until the conveying channel 8 is at the bottom of the crushing drum 2. After rotation, fix the position and start the electric push rod. The electric push rod drives the lifting frame 901 to move. When the lifting frame 901 moves, it drives the lifting frame 121 fixed at its top to move synchronously. The movement of the lifting frame 121 causes it to slide in the guide groove 122. Since the contact surface between the guide groove 122 and the lifting frame 121 is inclined, the connecting ring 123 is limited to the conveying channel 8, so that the lifting frame 121 drives the connecting ring 123 to rotate. The rotation of the connecting ring 123 causes... The elastic ropes 13 fixed to the inner wall are stretched, thereby increasing the distance between adjacent elastic ropes 13. At this time, the jujube powder can enter the conveying channel 8 through the barrier formed by the elastic ropes 13. The degree of rotation of the connecting ring 123 corresponds to the degree of stretching of the elastic ropes 13, so that the spacing of the elastic ropes 13 can be adjusted according to the degree of crushing. Different coarse jujube powders can be screened. The spacing can be flexibly controlled according to the degree of crushing. It can screen powders of different coarseness (ensuring that the powder entering the conveying channel 8 meets the requirements of ultrafine powder) and avoid the problem of easy clogging of traditional fixed screens.

[0065] As the lifting frame 901 moves, the limiting plate 902 fixed to its inner wall moves synchronously. When the limiting plate 902 moves, the first connecting column 905 and the second connecting column 908 slide in the groove 903, thereby driving the rotating disk 904 and the rotating ring 907 to rotate. When the rotating disk 904 and the rotating ring 907 rotate, the fixed shaft 906 and the sleeve 909 fixed to them rotate, thereby driving the first guide plate 10 and the second guide plate 11 fixed to the fixed shaft 906 and the sleeve 909 to rotate. The tilt angle of the first guide plate 10 and the second guide plate 11 is adjusted. The guide plates with different tilt angles can precisely control the material speed by changing the channel cross-sectional area and guiding the airflow direction. When the agglomerated particles flow through the guide plates with different tilt angles with the airflow, they will collide and rub against the guide plate surface multiple times, and the agglomerated structure will be destroyed. At the same time, the guide plates with different angles will change the local airflow direction, forming a small-scale turbulence, further dispersing the agglomerated particles, ensuring that the ultrafine powder entering the subsequent stage has a uniform particle size and meets the requirements of extraction or classification.

[0066] When the conveying channel 8 is at the top of the crushing barrel 2, during feeding, the lifting frame 901 moves, causing the elastic rope 13 to increase the gap and the first guide plate 10 and the second guide plate 11 to change their tilt angle, facilitating the feeding of the jujube. After feeding, the elastic rope 13 returns to its initial position. At this time, the gap of the elastic rope 13 is very small, which can form a barrier. If the floating fine powder comes into contact with the inner wall of the crushing barrel 2 for a long time (especially the upper part of the barrel that is not touched by the medium), it will adhere to the wall surface due to static electricity, molecular attraction, etc., and gradually accumulate to form an adhesion layer. During subsequent vibration, these adhesion layers may fall off and mix with the unpowdered powder. When fine materials are mixed, they form lumpy impurities, which disrupt the uniformity of the ultrafine powder's particle size. The barrier can physically intercept and reduce ineffective contact between the fine powder and the barrel wall, while simultaneously guiding the fine powder back to the medium area. Through this raw material pulverizing device based on the extraction of jujube ultrafine powder, the jujube ultrafine powder reaches a mesh size of 1000-3000 mesh. This not only makes the nutrients in the powder more easily absorbed by the human body, effectively improving product quality, but also gives the jujube powdered form an advantage in terms of space preservation, occupying less space and facilitating storage and transportation. At the same time, the powdered form makes it less prone to spoilage, extending the product's shelf life.
