Description

Technical Field

[0001] The present invention relates to the technical field of berry tea freeze-dried powder processing, and in particular to a continuous processing production line and method for berry tea freeze-dried powder. Background Art

[0002] Berry tea is a vine plant, and its leaves are rich in various nutrients, such as flavonoids, amino acids, vitamins, etc., and have the effects of clearing heat and detoxifying, anti-oxidation, and lowering blood pressure. In recent years, berry tea, as a natural health drink, has attracted more and more attention from consumers. In the production process of berry tea freeze-dried powder, in order to improve the processing efficiency of berry tea and the continuity of production and processing, it is generally necessary to feed the tea leaves through a conveyor belt. First, it is necessary to prepare the berry tea raw materials, and continuously convey the berry tea leaves to the cleaning pool through the conveyor belt for cleaning to remove dust and impurities on the surface. The cleaned berry tea leaves enter the drying link to remove moisture from the leaves. The next step is the extraction step. The dried berry tea leaves are mixed with water in a certain proportion and then The effective ingredients in the berry tea are extracted by heating and leaching. The extracted liquid is filtered to remove the residue to obtain a berry tea extract, and then vacuum concentration is used to remove excess water to increase the concentration of the extract. The concentrated berry tea extract enters the freezing stage, is poured into a freeze-drying tray, and placed in a quick-freezing bin or freezing equipment for freezing. The frozen berry tea extract enters the vacuum drying equipment through a feeding mechanism for drying. The vacuum-dried berry tea freeze-dried material is then discharged to the conveying mechanism through the discharge pipe at the bottom, and is conveyed to the crushing device through the conveying mechanism for crushing, and then sieving. Finally, the prepared berry tea freeze-dried powder is packaged and packed, and the packaged finished product is quality inspected to ensure that it meets relevant standards and quality requirements.

[0003] In the production process of freeze-dried berry tea powder, the whole block of berry tea is usually placed directly in a vacuum drying tank for drying. However, due to the large overall volume of the block of berry tea, the diffusion and evaporation path of its internal moisture is relatively long, resulting in the drying process taking a long time to complete.

[0004] In order to solve the above problems, the present application proposes a continuous processing production line and method for berry tea freeze-dried powder. Summary of the Invention

[0005] The present invention proposes a continuous processing production line and method for freeze-dried berry tea powder, which solves the problem in the related art of directly placing the entire block of berry tea in a vacuum drying tank for drying. Due to the large volume of the block of berry tea, the diffusion and evaporation path of the internal moisture is long, making the drying process time-consuming.

[0006] The present invention proposes a continuous processing production line for freeze-dried berry tea powder, comprising a vacuum drying tank, a filter cartridge, an elastic component and a drive component;

[0007] The filter cartridge is arranged in a vacuum drying tank, and the elastic component is installed on the filter cartridge;

[0008] A filter disc is installed in the filter cartridge, and the filter disc divides the filter cartridge into a first cavity and a second cavity. A plurality of first steel balls are arranged in the first cavity, and a plurality of second steel balls are arranged in the second cavity. The diameter of the first steel balls is larger than that of the second steel balls.

[0009] Both sides of the filter disc are equipped with spiral beating members that come into contact with the inner wall of the filter cartridge, and the two spiral beating members are respectively located in the first cavity and the second cavity;

[0010] The driving assembly is used to drive the filter cartridge to rotate and make it shake up and down under the action of the elastic assembly. When the filter cartridge shakes up and down, it drives the spiral beating member to follow the shaking and perform a beating action.

[0011] As a further optimization solution of the present invention, the elastic component includes a rotating disk and a rod-type elastic member, and the rotating disk is mounted on the filter cartridge via the rod-type elastic member;

[0012] The driving assembly includes a path guide, which is installed on the top of the vacuum drying tank. The rod-type elastic member is in conflict with the path guide. The driving assembly is used to drive the turntable to rotate, and the rod-type elastic member follows the rotation. Under the action of the path guide, the rod-type elastic member is elastically deformed to drive the filter cartridge to shake up and down.

[0013] As a further optimization scheme of the present invention, the rod-type elastic member includes a limit rod, and a plurality of circumferentially arranged limit rods are slidably connected to the turntable. A first ball that interferes with the path guide is rollingly installed on the limit rod, and a first spring is sleeved on the limit rod, and the two ends of the first spring are respectively connected to the turntable and the filter cartridge.

[0014] As a further optimized solution of the present invention, the path guide includes a fixed plate, the fixed plate is installed at the top of the vacuum drying tank, and a plurality of circumferentially distributed hemispheres are installed at the bottom of the fixed plate. The first balls are in contact with the bottom of the fixed plate, and the first balls correspond to the circumferential paths of the hemispheres.

[0015] The driving assembly further comprises a motor, which is mounted on the top of the vacuum drying tank. The output end of the motor is connected to a rotating rod, and the bottom end of the rotating rod rotates through the fixed disk and is connected to the rotating disk.

[0016] As a further optimization scheme of the present invention, the spiral beating member includes a spiral elastic tube, and spiral elastic tubes that interfere with the inner wall of the filter cartridge are installed on both sides of the filter disc. The two spiral elastic tubes are respectively located in the first cavity and the second cavity, and the inner wall of the spiral elastic tube is installed with several circumferentially arranged beating rods.

[0017] As a further optimization solution of the present invention, an elastic auxiliary component for supporting the bottom of the filter cartridge is installed in the vacuum drying tank;

[0018] The elastic auxiliary component includes an auxiliary cylinder. A plurality of circumferentially arranged auxiliary cylinders are installed at the bottom of the vacuum drying tank. Elastic support members are installed on the auxiliary cylinders, and the elastic support members support the edge of the bottom of the filter cylinder.

[0019] As a further optimization scheme of the present invention, the elastic support member includes a second spring and a support rod. The second spring is installed in the auxiliary tube. A support rod connected to the second spring is slidably passed through the auxiliary tube. A second ball is rollingly installed on the support rod, and the second ball rolls with the edge of the bottom of the filter tube.

[0020] As a further optimization scheme of the present invention, a second filter hole is provided on the filter disc, a first filter hole is provided at the bottom of the filter cartridge, the aperture of the second filter hole is larger than the aperture of the first filter hole, and a feed port connected to the first cavity is provided at the top of the filter cartridge.

[0021] As a further optimized solution of the present invention, an end cover is installed on the top of the vacuum drying canister, a discharge pipe is installed on the bottom of the vacuum drying canister, and a valve body is installed on the discharge pipe.

[0022] A method for continuously processing and producing berry tea freeze-dried powder, using the above-mentioned continuous processing production line for berry tea freeze-dried powder, comprises the following steps:

[0023] Step 1: Raw material pretreatment: The berry tea leaves are continuously transported to the cleaning pool through a conveyor belt for cleaning, and then dried, extracted, filtered, vacuum concentrated, and frozen in sequence;

[0024] Step 2: Vacuum drying: Open the end cover of the vacuum drying tank, put the frozen block berry tea into the first cavity through the feed port on the filter cartridge, start the vacuum drying tank, and vacuum dry the block berry tea in the filter cartridge;

[0025] Step 3: Primary crushing: The filter cartridge is driven to rotate by the driving component and vibrates up and down under the action of the elastic component. When the filter cartridge rotates and vibrates, the first steel balls in the first cavity collide with each other to crush the berry tea. The crushed berry tea powder is filtered into the second cavity through the filter disc. The first steel balls also absorb heat in the filter cartridge. When the first steel balls collide with and crush the berry tea blocks, the heat can be directly applied to the crushed berry tea powder.

[0026] Step 4: Secondary crushing: After the berry tea powder enters the second cavity, the filter cartridge rotates and shakes, causing the second steel balls in the second cavity to further impact and crush the berry tea powder. When the second steel balls collide with each other, they can grind the berry tea powder. After the berry tea powder is ground into specifications, it is discharged through the first filter hole at the bottom of the filter cartridge;

[0027] Step 5: Beating action: When the filter cartridge rotates and shakes, the spiral beating members on both sides of the filter disc can be driven to shake simultaneously. The spiral beating members located in the first cavity and the second cavity can beat the berry tea powder to loosen the berry tea powder. When the spiral beating member located in the second cavity shakes, it can beat the bottom of the filter cartridge to accelerate the discharge of the berry tea powder in the second cavity.

[0028] Step 6: Discharge: After the berry tea powder is crushed and dried, it is discharged through the discharge pipe and enters the next processing step.

[0029] The above technical solution of the present invention has the following beneficial technical effects:

[0030] 1. The present invention sequentially cleans, dries, extracts, filters, vacuum concentrates, and freezes the berry tea raw materials, then opens the end cover on the vacuum drying tank, aligns the feeding mechanism with the feeding port on the filter cartridge, guides the block berry tea into the first cavity in the filter cartridge through the feeding mechanism, and then closes the end cover for vacuum drying. Since the overall volume of the block berry tea is large and the drying time is long, the turntable can be driven to rotate by the driving component. When the rod-type elastic member on the turntable passes through the hemispherical position at the bottom of the path guide member, the rod-type elastic member can be elastically deformed under the reaction force, forcing the filter cartridge to shake up and down. When the filter cartridge rotates and shakes, the first steel balls in the first cavity collide with each other to crush the berry tea. The crushed berry tea powder passes through the filter disc and is filtered into the second cavity. The first steel balls also absorb heat in the filter cartridge. When the first steel balls collide and crush the block berry tea, the heat can be directly applied to the block berry tea, thereby accelerating the diffusion and evaporation rate of water inside the berry tea, effectively shortening the drying time, and improving the drying efficiency.

[0031] 2. After the berry tea powder is filtered into the second cavity, the filter cartridge rotates and shakes, and the second steel balls in the second cavity further impact and crush the berry tea powder. Since the diameter of the second steel balls is smaller than that of the first steel balls, the second steel balls can grind the berry tea powder when they collide with each other. The present invention can double-crush the blocky berry tea, accelerate the drying of the berry tea powder, and reduce the time required for drying. After the berry tea powder is ground into specifications, it is discharged to the bottom of the vacuum drying tank through the first filter hole opened at the bottom of the filter cartridge. The berry tea powder is then discharged through the discharge pipe and conveyed to the next process for sub-packaging and packaging through the conveying mechanism. The above design can integrate drying, crushing, screening and grinding into one, making the device highly integrated and reducing equipment costs.

[0032] 3. When the filter cartridge is rotated and shaken by the present invention, the spiral beating members on both sides of the filter disc can be driven to shake simultaneously. The spiral beating members located in the first cavity and the second cavity can beat the berry tea, loosen the berry tea powder, enhance its fluidity, and effectively reduce the phenomenon of berry tea powder clogging in the filter cartridge. Since the spiral beating members contact the inner wall of the filter cartridge, the spiral beating members can scrape the inner wall of the filter cartridge when shaking, preventing the berry tea powder from adhering to the inner wall of the filter cartridge, further ensuring the smooth flow of the material. When the spiral beating members located in the second cavity are shaken, they can beat the bottom of the filter cartridge, accelerating the discharge of the berry tea powder in the second cavity, thereby improving the operating efficiency of the entire device.

[0033] 4. The present invention provides a structure for supporting the bottom of the filter cartridge at the bottom of the vacuum drying tank. When the filter cartridge rotates and shakes, the elastic auxiliary component can undergo corresponding elastic deformation to provide auxiliary support for the filter cartridge. This elastic auxiliary support structure can effectively buffer the impact force generated by the filter cartridge during the shaking process and reduce direct collision between the filter cartridge and the bottom of the vacuum drying tank.

[0045] To make the objectives, technical solutions, and advantages of the present invention more clearly understood, the present invention will be further described in detail below in conjunction with specific embodiments and with reference to the accompanying drawings. It should be understood that these descriptions are merely exemplary and are not intended to limit the scope of the present invention. In addition, in the following description, descriptions of well-known structures and technologies are omitted to avoid unnecessary confusion of the concepts of the present invention.

[0046] like Figure 1-10 As shown, the present invention proposes a continuous processing production line for freeze-dried berry tea powder, comprising a vacuum drying tank 1, a filter cartridge 2, an elastic component 3 and a driving component 4;

[0047] The filter cartridge 2 is arranged in the vacuum drying tank 1, and the elastic component 3 is installed on the filter cartridge 2;

[0048] A filter disc 21 is installed in the filter cartridge 2, and the filter disc 21 divides the filter cartridge 2 into a first cavity 22 and a second cavity 23. A plurality of first steel balls 221 are disposed in the first cavity 22, and a plurality of second steel balls 231 are disposed in the second cavity 23. The diameter of the first steel balls 221 is larger than that of the second steel balls 231.

[0049] Both sides of the filter disc 21 are equipped with spiral beating members 24 that come into contact with the inner wall of the filter cartridge 2. The two spiral beating members 24 are located in the first cavity 22 and the second cavity 23 respectively.

[0050] The driving assembly 4 is used to drive the filter cartridge 2 to rotate and vibrate up and down under the action of the elastic assembly 3. When the filter cartridge 2 vibrates up and down, it drives the spiral flapping member 24 to follow the vibration and perform a flapping action.

[0051] During actual work, the berry tea raw materials are sequentially cleaned, dried, extracted, filtered, vacuum concentrated, and frozen, and then the end cover 101 on the vacuum drying tank 1 is opened, and the feeding mechanism is aligned with the feeding port 201 on the filter cartridge 2 (the feeding mechanism is not shown in the figure), and the block berry tea is guided into the first cavity 22 in the filter cartridge 2 through the feeding mechanism, and then the end cover 101 is closed for vacuum drying. It should be noted that the feeding mechanism is an elevator, and the discharge pipe of the elevator is connected to the telescopic guide pipe, which is inserted into the feeding port 201 for guiding the material. After the guiding is completed, the telescopic pipe is pulled out of the vacuum drying tank 1, and then the filter cartridge 2 is driven to rotate by the driving component 4. At the same time, the elastic component 3 causes the filter cartridge 2 to shake up and down under the action of the driving component 4. During the rotation and shaking of the filter cartridge 2, the filter cartridge 2 is pulled out of the vacuum drying tank 1. During the drying process, the first steel balls 221 in the first cavity 22 will collide with each other due to the movement of the filter cartridge 2. The mutual collision of the first steel balls 221 will generate an impact force on the block berry tea, thereby breaking the block berry tea into powder to accelerate the drying of the berry tea. The broken berry tea powder is filtered through the filter disc 21 and enters the second cavity 23. Since the first steel balls 221 absorb heat in the filter cartridge 2, they can directly transfer the heat to the broken berry tea powder when colliding and breaking the block berry tea, thereby accelerating the diffusion and evaporation rate of the moisture inside the berry tea and improving the drying efficiency. Moreover, the up and down shaking of the filter cartridge 2 drives the spiral flapping member 24 to vibrate. The spiral flapping member 24 located in the first cavity 22 has the effect of flapping and loosening the block berry tea and the powder in the crushing process, thereby enhancing its fluidity and reducing blockage.

[0052] like Figure 3 and Figure 4 As shown, in this embodiment, the elastic component 3 includes a rotating disk 31 and a rod-type elastic member 32, and the rotating disk 31 is installed on the filter cartridge 2 through the rod-type elastic member 32;

[0053] The driving assembly 4 includes a path guide 43, which is installed at the top of the vacuum drying tank 1. The rod-type elastic member 32 conflicts with the path guide 43. The driving assembly 4 is used to drive the turntable 31 to rotate, and the rod-type elastic member 32 rotates accordingly. Under the action of the path guide 43, the rod-type elastic member 32 elastically deforms to drive the filter cartridge 2 to shake up and down.

[0054] The driving assembly 4 drives the turntable 31 to rotate. When the turntable 31 rotates, the rod-type elastic member 32 installed thereon also rotates. During the rotation process, the rod-type elastic member 32 will conflict with the path guide member 43 installed at the top of the vacuum drying tank 1. Under the action of the path guide member 43, the rod-type elastic member 32 will be elastically deformed. Since the rod-type elastic member 32 is connected to the filter cartridge 2, this elastic deformation will drive the filter cartridge 2 to shake up and down, which can ensure that the first steel ball 221 and the second steel ball 231 have a more uniform crushing and grinding effect on the berry tea. At the same time, the stable shaking also makes the beating action of the spiral beating member 24 more regular, better loosens the material, and prevents the material from accumulating and clogging in the filter cartridge 2.

[0055] like Figure 4 and Figure 5 As shown, in this embodiment, the rod-type elastic member 32 includes a limiting rod 321, and a plurality of circumferentially arranged limiting rods 321 are slidably connected to the turntable 31. A first ball 323 that contacts the path guide member 43 is rollingly mounted on the limiting rod 321. A first spring 322 is sleeved on the limiting rod 321, and the two ends of the first spring 322 are respectively connected to the turntable 31 and the filter cartridge 2.

[0056] When the turntable 31 rotates under the drive assembly 4, the first ball 323 on the limit rod 321 will roll along the path guide 43. During the rolling process, it will be subjected to a reaction force. This reaction force is transmitted to the limit rod 321 through the first ball 323, causing the limit rod 321 to slide on the turntable 31 and stretch the first spring 322. The first spring 322 undergoes elastic deformation. Since its two ends are respectively connected to the turntable 31 and the filter cartridge 2, the elastic force generated by the elastic deformation will drive the filter cartridge 2 to move up and down. The setting of the limit rod 321 and the first ball 323 makes the rod-type elastic member 32 smoother during the movement, reduces the influence of friction, and improves the working efficiency of the elastic assembly 3. The first spring 322 not only provides the elastic force to make the filter cartridge 2 shake up and down, but also plays a buffering role to prevent the filter cartridge 2 from being damaged by excessive impact force during the shaking process.

[0057] like Figure 4 As shown, in this embodiment, the path guide 43 includes a fixed plate 431, which is installed on the top of the vacuum drying tank 1. A plurality of circumferentially distributed hemispherical bodies 432 are installed on the bottom of the fixed plate 431. The first rolling ball 323 contacts the bottom of the fixed plate 431, and the first rolling ball 323 corresponds to the circumferential path of the hemispherical body 432.

[0058] The driving assembly 4 further includes a motor 41 , which is mounted on the top of the vacuum drying tank 1 . The output end of the motor 41 is connected to a rotating rod 42 , and the bottom end of the rotating rod 42 rotates through the fixed disk 431 and is connected to the rotating disk 31 .

[0059] After the motor 41 is started, its output end drives the rotating rod 42 to rotate. The rotating rod 42 passes through the fixed plate 431 and is connected to the turntable 31, thereby driving the turntable 31 to rotate. When the turntable 31 rotates, the first ball 323 on the rod-type elastic member 32 rolls at the bottom of the fixed plate 431. When the first ball 323 passes through the hemispheres 432 distributed circumferentially at the bottom of the fixed plate 431, the hemispheres 432 will change the movement direction of the first ball 323, so that the first ball 323 generates a vertical force on the limiting rod 321. This force causes the limiting rod 321 to stretch the first spring 322, thereby driving the filter cartridge 2 to shake up and down. The circumferential distribution design of the hemispheres 432 can ensure that the filter cartridge 2 can shake up and down multiple times during the process of the turntable 31 rotating one circle, thereby increasing the crushing and beating effect of the berry tea.

[0060] like Figure 6 、 Figure 7 and Figure 8 As shown, in this embodiment, the spiral beating member 24 includes a spiral elastic tube 241, and spiral elastic tubes 241 that interfere with the inner wall of the filter cartridge 2 are installed on both sides of the filter disc 21. The two spiral elastic tubes 241 are respectively located in the first cavity 22 and the second cavity 23, and the inner wall of the spiral elastic tube 241 is installed with several circumferentially arranged beating rods 242.

[0061] During the rotation and shaking of the filter cartridge 2, the spiral elastic tube 241 will move with the filter cartridge 2. Since the spiral elastic tube 241 is elastic, it will undergo elastic deformation during shaking. This deformation will cause the beating rod 242 installed on its inner wall to move in different directions. The spiral elastic tube 241 and the beating rod 242 located in the first cavity 22 will beat the blocky berry tea and the powder in the crushing process at multiple angles when the filter cartridge 2 rotates and shakes, further loosening the material and preventing agglomeration. The spiral elastic tube 241 and the beating rod 242 located in the second cavity 23 will not only beat and loosen the berry tea powder, but also beat the bottom of the filter cartridge 2 during shaking, accelerating the discharge of the berry tea powder in the second cavity 23 through the first filter hole 202, thereby improving the efficiency of the entire processing process. The design of the spiral elastic tube 241 and the beating rod 242 increases the diversity and strength of the beating effect, which can better meet the needs of material processing at different stages.

[0062] like Figure 3 、 Figure 9 and Figure 10 As shown, in this embodiment, an elastic auxiliary component 5 for supporting the bottom of the filter cartridge 2 is installed in the vacuum drying tank 1;

[0063] The elastic auxiliary component 5 includes an auxiliary cylinder 51 . A plurality of circumferentially arranged auxiliary cylinders 51 are installed at the bottom of the vacuum drying tank 1 . Elastic support members 52 are installed on the auxiliary cylinders 51 , and the elastic support members 52 support the edge of the bottom of the filter cartridge 2 .

[0064] When the filter cartridge 2 rotates and shakes under the action of the drive assembly 4 and the elastic assembly 3, the bottom of the filter cartridge 2 will generate pressure on the elastic auxiliary assembly 5. The elastic support member 52 in the elastic auxiliary assembly 5 is installed on the auxiliary cylinder 51. Multiple circumferentially arranged auxiliary cylinders 51 can evenly support the bottom edge of the filter cartridge 2. During the shaking process of the filter cartridge 2, the elastic support member 52 will undergo elastic deformation to adapt to the movement of the filter cartridge 2. This elastic deformation acts as a buffer, reducing the direct collision between the filter cartridge 2 and the bottom of the vacuum drying tank 1, protecting the filter cartridge 2 and the vacuum drying tank 1, and extending the service life of the equipment.

[0065] like Figure 10 As shown, in this embodiment, the elastic support member 52 includes a second spring 521 and a support rod 522. The second spring 521 is installed in the auxiliary tube 51. The auxiliary tube 51 is slidably connected with a support rod 522 connected to the second spring 521. A second ball 523 is rollingly installed on the support rod 522, and the second ball 523 rolls with the edge of the bottom of the filter cartridge 2.

[0066] When the filter cartridge 2 shakes and applies pressure to the elastic support 52, the support rod 522 will slide on the auxiliary cylinder 51, squeezing the second spring 521. The second spring 521 undergoes elastic deformation, and the generated elastic force is transmitted to the filter cartridge 2 through the support rod 522, playing a role of buffering and supporting. The second ball 523 rollingly installed on the support rod 522 rolls with the bottom edge of the filter cartridge 2. This can reduce the friction between the support rod 522 and the filter cartridge 2, making the filter cartridge 2 smoother during the shaking process and reducing energy loss. At the same time, the rolling of the second ball 523 can better adapt to the slight displacement changes of the bottom edge of the filter cartridge 2 during the shaking process, thereby ensuring the stability of the elastic support and further improving the reliability of the equipment operation.

[0067] like Figure 6 As shown, in this embodiment, a second filter hole 211 is provided on the filter disc 21, a first filter hole 202 is provided at the bottom of the filter cartridge 2, the aperture of the second filter hole 211 is larger than the aperture of the first filter hole 202, and a feed port 201 connected to the first cavity 22 is provided at the top of the filter cartridge 2.

[0068] During the processing, the berry tea powder crushed by the first steel ball 221 in the first cavity 22 enters the second cavity 23 through the second filter hole 211 on the filter disc 21. The larger aperture of the second filter hole 211 can ensure that the crushed powder passes smoothly to avoid blockage. The powder entering the second cavity 23 is further impacted, crushed and ground by the second steel ball 231, and the berry tea powder that meets the specifications is discharged through the first filter hole 202 at the bottom of the filter cartridge 2. The smaller aperture of the first filter hole 202 can screen the powder, and only powder that reaches a certain fineness can be discharged, ensuring the quality of the discharged berry tea powder. The feed port 201 is used to feed the frozen block berry tea into the first cavity 22, providing a raw material entrance for the entire processing process, and ensuring the continuous operation of the production line.

[0069] like Figure 1 and Figure 2 As shown, in this embodiment, an end cover 101 is installed on the top of the vacuum drying tank 1 , a discharge pipe 102 is installed on the bottom of the vacuum drying tank 1 , and a valve body 103 is installed on the discharge pipe 102 .

[0070] Before processing, the end cover 101 is opened to facilitate the placement of the frozen block berry tea into the filter cartridge 2 through the feed port 201. During processing, the end cover 101 is closed to ensure the vacuum environment in the vacuum drying tank 1, which is conducive to the drying of the berry tea. When the berry tea powder has completed the drying, crushing, and screening processes, the valve body 103 is opened, and the berry tea powder is discharged through the discharge pipe 102 and transported to the next process by the conveying mechanism, which uses a conveyor belt (not shown in the figure) to enter the next process. The configuration of the end cover 101 and valve body 103 makes the operation of the equipment more convenient, can effectively control the entry and exit of materials, ensure the smooth progress of the processing process and the stability of the environment in the vacuum drying tank 1.

[0071] A method for continuously processing and producing berry tea freeze-dried powder, using the above-mentioned continuous processing production line for berry tea freeze-dried powder, comprises the following steps:

[0072] Step 1: Raw material pretreatment: The berry tea leaves are continuously transported to the cleaning pool through a conveyor belt for cleaning, and then dried, extracted, filtered, vacuum concentrated, and frozen in sequence;

[0073] Step 2: Vacuum drying: Open the end cover 101 on the vacuum drying tank 1, put the frozen block berry tea into the first cavity 22 through the feed port 201 on the filter cartridge 2, start the vacuum drying tank 1, and vacuum dry the block berry tea in the filter cartridge 2;

[0074] Step 3: Primary crushing: The filter cartridge 2 is rotated by the driving component 4 and vibrates up and down under the action of the elastic component 3. When the filter cartridge 2 rotates and vibrates, the first steel balls 221 in the first cavity 22 collide with each other to crush the berry tea. The crushed berry tea powder passes through the filter disc 21 and is filtered into the second cavity 23. The first steel balls 221 also absorb heat in the filter cartridge 2. When the first steel balls 221 collide with and crush the berry tea blocks, the heat can be directly applied to the crushed berry tea powder.

[0075] Step 4: Secondary crushing: After the berry tea powder enters the second cavity 23, the filter cartridge 2 rotates and shakes, causing the second steel balls 231 in the second cavity 23 to further impact and crush the berry tea powder. When the second steel balls 231 collide with each other, they grind the berry tea powder. After the berry tea powder is ground to specifications, it is discharged through the first filter hole 202 at the bottom of the filter cartridge 2.

[0076] Step 5: Beating action: When the filter cartridge 2 rotates and shakes, the spiral beating members 24 on both sides of the filter disc 21 can be driven to shake simultaneously. The spiral beating members 24 located in the first cavity 22 and the second cavity 23 can beat the berry tea powder to loosen the berry tea powder. When the spiral beating members 24 located in the second cavity 23 shake, they can beat the bottom of the filter cartridge 2 to accelerate the discharge of the berry tea powder in the second cavity 23.

[0077] Step 6: Discharge: After the berry tea powder is crushed and dried, it is discharged through the discharge pipe 102 and enters the next processing step.

[0078] The specific working principle of the present invention is as follows:

[0079] First, the berry tea raw materials are pretreated to prepare for subsequent processing. The pretreated frozen block berry tea is placed into the first cavity 22 of the filter cartridge 2 from the feed port 201. The end cover 101 is closed and the vacuum drying tank 1 is started for vacuum drying. The motor 41 of the driving component 4 drives the rotating rod 42 to rotate, driving the turntable 31 to rotate, so that the rod-type elastic member 32 interacts with the path guide member 43, prompting the filter cartridge 2 to rotate and shake up and down. The first steel balls 221 in the first cavity 22 collide with each other when the filter cartridge 2 shakes, breaking the block berry tea. The heat transfer accelerates the evaporation of water, and the broken powder passes through the filter disc 21. Entering the second cavity 23, in the second cavity 23, the second steel ball 231 further crushes and grinds the powder, and the qualified powder is discharged from the first filter hole 202. At the same time, the shaking of the filter cartridge 2 drives the spiral beating member 24 to beat and loosen the berry tea powder to prevent clogging. The spiral beating member 24 in the second cavity 23 also accelerates the discharge of the powder. Finally, the valve body 103 is opened, and the processed berry tea powder is discharged through the discharge pipe 102 to enter the next process. The whole process realizes the continuous processing of berry tea freeze-dried powder, integrating drying, crushing, screening and grinding, thereby improving production efficiency and product quality.

[0080] It should be understood that the above-described specific embodiments of the present invention are merely illustrative of or explanation of the principles of the present invention and are not intended to limit the present invention. Therefore, any modifications, equivalent substitutions, improvements, etc. made without departing from the spirit and scope of the present invention shall be included within the scope of protection of the present invention.
